Notwithstanding the foregoing, the following sales of a Licensed Product shall be excluded from Net Sales calculations for all purposes: (i) transfer or dispositions of reasonable quantities of samples of such Licensed Product at no cost for promotional or educational purposes; (ii) transfers or dispositions of reasonable and customary quantities of such Licensed Product as free samples or donations, or for patient assistance, testing marketing programs or other similar programs at no cost; and (iii) use or sale of such Licensed Product for Clinical Trial or other scientific testing purposes, early access programs (such as to provide patients with such Licensed Product prior to Marketing Approval pursuant to treatment INDs or protocols, named patient programs or compassionate use programs) or any similar use.

In the event a Licensed Product is sold as part of a Combination Product in a country, the Net Sales with respect to the Combination Product in such country (for all financial terms pursuant to Article 7) shall be determined by multiplying the Net Sales amount for the Combination Product during the applicable reporting period, calculated as set forth above, by the fraction A/(A+B), where A is the weighted average sale price (by sales volume) of the Licensed Product in such country when sold separately, and B is the weighted average sales price of the other active ingredient(s) or product(s) in the Combination Product in such country when sold separately, in each case in the same dosage and dosage form and in the same country as the Combination Product during the applicable reporting period. If the other active ingredient(s) or product(s) in the Combination Product is not sold separately in such country during the applicable reporting period, Net Sales shall be calculated by multiplying actual Net Sales of such Combination Product by a fraction A/C where A is the weighted average sale price (by sales volume) of the Licensed Product in such country when sold separately, and C is the weighted average sale price

(by sales volume) of the Combination Product in such country. If neither the Licensed Product nor the other active ingredient(s) or product(s) were sold separately in such country during the applicable reporting period, then the respective average sales prices during the most recent reporting period in which sales of both occurred in the same country as the Combination Product shall be used. In the event that the weighted average sale price (by sales volume) of the Licensed Product is not available in a given country for any reporting period, then the average sales prices (weighted by sales volume) of the respective products described above (in the same dosage and dosage form as the Combination Product) in a proxy country to be agreed upon by both Parties will be used (such agreement not be unreasonably withheld, delayed or conditioned), and if the Parties cannot agree upon such proxy country, or no such comparable sales figures are available in an appropriate proxy country, Net Sales for the applicable Combination Product shall be allocated based on the relative value contributed by each component (such relative value to be agreed upon by the Parties or, if the Parties cannot agree, to be determined by the dispute resolution procedures set forth in Article 13).

Article 2
GOVERNANCE

2.1. Joint Steering Committee.

2.1.1. Formation, Composition and Term of JSC.

(a) Within [ * ] after the Effective Date, the Parties will establish a joint steering committee (the “JSC”) to oversee and coordinate the Parties’ activities during the Development Term and, following the Opt-In Effective Date (except as described in Section 2.1.4(c)(4)), to serve solely as an information-sharing body in accordance with Section 5.3.2.

(b) The JSC initially shall be composed of [ * ] members, [ * ] of whom shall be representatives appointed by Protagonist and [ * ] of whom shall be representatives appointed by Janssen, each with the requisite experience and seniority to enable such representative to make decisions on behalf of the Parties with respect to the issues falling within the jurisdiction of the JSC. Neither Party shall appoint any representative to the JSC that is not an employee of such Party or one of its Affiliates without the prior written consent of the other Party, which consent shall not be unreasonably withheld. Each Party shall appoint one (1) of its representatives as co-chairperson of the JSC. The size of the JSC may be changed from time to time by written agreement of the Parties, provided that the JSC shall at all times include an equal number of representatives of each Party. Each Party may replace its JSC representatives at any time upon written notice to the other Party.

(c) After the Development Term, the JSC shall have no oversight or decision-making authority and shall serve solely as an information-sharing body in accordance with Section 5.3.2. The JSC shall automatically dissolve when Janssen has no further reporting obligations under Section 5.3.2 (or such later time as agreed by the Parties).

2.1.2. Subcommittees.

(a) The Parties shall establish a Joint Manufacturing Committee (“JMC”) promptly after establishing the JSC. The purpose of the JMC will be to oversee and coordinate the Parties’ performance of the Collaboration CMC Activities during the Development Term, to share information and facilitate the performance and execution of such activities, and to review and discuss potential changes to the CMC Development Plan and to Third Party manufacturers of clinical supplies for the Phase 1 Activities and Phase 2 Activities.

(b) The JSC may, as necessary or appropriate and agreed to by the JSC, establish other subcommittees and delegate tasks within its authority as expressly provided for hereunder to such subcommittees (the JMC and each other subcommittee, a “Subcommittee”). Each Subcommittee shall operate in the same manner as the JSC, as described in Section 2.1.4, provided that no Subcommittee shall have any decision-making authority, but shall instead make recommendations to the JSC with respect to such matters within its authority.

(c) All Subcommittees shall automatically dissolve upon the end of the Development Term (or such later time as agreed by the Parties).

2.1.3. Responsibilities of the JSC During Development Term. The JSC shall oversee the Collaboration Activities during the Development Term. In particular, the JSC shall:

(a) review and approve proposed amendments to the Clinical Development Plan (including the Phase 2 Development Budget) and CMC Development Plan (including the Phase 2 CMC Development Budget) in accordance with Section 3.2.2;

(b) review and discuss the results of the Collaboration Activities;

(c) decide matters presented to it by any Subcommittee, in each case, that is within the scope of responsibilities delegated to the respective Subcommittee under this Agreement or by the JSC; and

(d) perform such other functions as expressly set forth in this Agreement or as mutually agreed upon by the Parties in writing.

2.1.4. JSC Operations.

(a) Meetings. During the Development Term, the JSC shall hold meetings at least [ * ] or as often as its members may determine. Thereafter, the JSC shall hold meetings at least [ * ]. JSC meetings may be held in person or by any means of telecommunications as the members deem necessary or appropriate, including telephone, video conference or similar means in which each participant can hear what is said, and be heard, by the other participants, provided that, unless otherwise agreed by the Parties the location of any in-person meetings shall alternate between a location chosen by Protagonist and a location chosen by Janssen. A quorum of the JSC shall exist whenever there is present at a meeting at least one (1) representative appointed by each Party. Employees or consultants of either Party who are performing Collaboration Activities or other Development or Manufacturing activities hereunder but are not members of JSC may attend meetings of the JSC relating to such activities, provided that (i) such attendees shall not vote or otherwise participate in the decision-making process of the JSC, (ii) such attendees shall be bound in writing by obligations of confidentiality and non-use equivalent to those set forth in Article 9 and (iii) a consultant of a Party

may attend a meeting only with prior notice to and consent of the other Party, which shall not be unreasonably withheld. Except as provided in the prior sentence, individuals who are not members of the JSC may not attend a meeting of the JSC without the prior consent of both Parties, except that each Party’s Alliance Manager may attend without such consent. Each Party shall be responsible for its own expenses of participating in the JSC and in any Subcommittee.

(b) Agenda and Minutes. Each Party shall have the right to propose agenda items and shall provide all appropriate information with respect to such proposed agenda items in advance of each JSC meeting. Each co-chairperson of the JSC, on an alternating basis, shall prepare and circulate to all members of the JSC for review draft minutes of each JSC meeting within thirty (30) days after such meeting. The Parties shall agree on the minutes of each meeting promptly, but in no event later than the next meeting of the JSC, provided that, if the Parties cannot agree as to the content of the minutes by the time of the next JSC meeting, such minutes shall be finalized to reflect any areas of disagreement. The minutes of each meeting of the JSC shall be Collaboration Information.

(1) The JSC shall make decisions and take action (A) by consensus of the members present at a meeting at which a quorum exists, with each Party ensuring that its representatives make such decisions in good faith, and having a single vote irrespective of the number of representatives of such Party in attendance, or (B) by a written resolution signed by at least both co-chairpersons appointed by each Party.

(2) If the JSC does not reach consensus on any matter within its authority (a “Deadlocked Matter”) within a period of [ * ] (or such other period as the Parties may agree in writing) after it has met and attempted to reach such consensus, then either Party may, by written notice to the other Party, refer the Deadlocked Matter to the Executive Officers; provided, however, that, if the Executive Officers do not reach agreement on such Deadlocked Matter within [ * ] after such Deadlocked Matter is referred to the Executive Officers, then, subject to Sections 2.1.4(c)(3) and 2.1.4(c)(4):

(i) Protagonist shall have the final decision-making right with respect to any Deadlocked Matter to the extent it relates to Phase 1 Activities or to Collaboration CMC Activities for the Phase 1 Activities, which decision shall be final and binding on the Parties;

(ii) During the period prior to the date when the JSC determines pursuant to Section 3.3.3 (or Protagonist determines pursuant to 2.1.4(c)(2)(iii) below) that the results from the Phase 1 Activities support continuation of preparation and conduct of the CD Phase 2 Clinical Trial, Protagonist shall have the final decision-making right with respect to any Deadlocked Matter to the extent it relates to Phase 2 Activities (but not Collaboration CMC Activities for the Phase 2 Activities), which decision shall be final and binding on the Parties; provided, however, that Protagonist may not exercise its final decision-making authority under this Section 2.1.4(c)(2)(ii) to make any Fundamental Development Plan Change or to approve or amend the Phase 2 Development Budget without Janssen’s consent, which shall not be unreasonably withheld, delayed or conditioned;

(iii) Protagonist shall have the final decision-making right with respect to any Deadlocked Matter to the extent it relates to whether the results from the Phase 1 Activities support continuation of preparation and conduct of the CD Phase 2 Clinical Trial, which decision shall be final and binding on the Parties; provided, however, that Protagonist may not exercise its final decision-making authority under this Section 2.1.4(c)(2)(iii) to make any Fundamental Development Plan Change or to approve or amend the Phase 2 Development Budget without Janssen’s consent, which shall not be unreasonably withheld, conditioned or delayed;

(iv) Janssen shall have the final decision-making right with respect to any Deadlocked Matter to the extent it relates to Collaboration CMC Activities for any Phase 3 Clinical Trial, which decision shall be final and binding on the Parties except that Janssen may not exercise its final decision-making authority under this Section 2.1.4(c)(2)(iv) to assign to Protagonist

any such Collaboration CMC Activities that are not already assigned to Protagonist under the then-current CMC Development Plan having last been approved by both Parties, without Protagonist’s consent; and

(v) Neither Party shall have the final decision-making right with respect to any Deadlocked Matter which is other than as described in Sections 2.1.4(c)(2)(i) through (iv), including for example and without limitation, whether to effect any Fundamental Development Plan Change, and in such event the matter shall remain deadlocked and the status quo shall persist unless and until the Parties reach agreement on such matter; provided, however, that, to the extent the Deadlocked Matter is with respect to a Fundamental Development Plan Change, the Parties shall proceed under the then-current Clinical Development Plan (including the then-current Phase 2 Development Budget) having last been approved by both Parties.

5.6.2. Protagonist Co-Detailing Option.

(a) Definitions.

(1) “Detail” means one (1) Primary Call or two (2) Secondary Calls. E-details, sample drops (if applicable) and reminder details shall not constitute a Detail. With regard to presentations made at conventions or similar gatherings, Details shall include that number of Details represented by the members of the target audience in attendance. For the avoidance of doubt, Details may occur in group situations if the definition of a Detail is met.

(2) “Primary Call” means a one-on-one in-person contact in which a sales representative makes a presentation, including selling message and features and benefits of a pharmaceutical or biologic product to a healthcare professional having prescribing authority within the target audience, during which contact such product is [ * ].

(3) “Restricted Change of Control” means, with respect to Protagonist, a Change of Control in which the Acquirer: (A) has, as of the time of such Change of Control a field sales force in the United States that promotes any pharmaceutical product for any IBD Indication (as defined in Section 6.7.2), (B) has entered into or become the subject of a corporate integrity agreement, settlement or order with or of the Office of Inspector General, U.S. Department of Health and Human Services, or another Governmental Authority, relating to marketing or commercialization of pharmaceutical products, (C) is the subject of a bona fide investigation or proceeding with the Office of Inspector General, U.S. Department of Health and Human Services, or another Governmental Authority, with respect to the marketing or commercialization of pharmaceutical products or (D) is engaged in significant litigation or other significant legal dispute with Janssen or any of its Affiliates, as evidenced by written

correspondence outlining the issues in such dispute, ongoing alternative dispute resolution proceedings or an active court case.

(4) “Secondary Call” means a one-on-one in-person contact in which a sales representative makes a presentation, including selling message and features and benefits of a pharmaceutical or biologic product to a healthcare professional having prescribing authority within the target audience, in which such product is [ * ].

(b) Co-Detailing Option. Janssen hereby grants Protagonist an option to provide, at Protagonist’s election, up to thirty percent (30%) of the Details for each Licensed Product (other than Combination Products) in the U.S. for all approved Indications, as further described in this Section 5.6.2 (the “Co-Detailing Option”). Notwithstanding the foregoing, if Protagonist does not exercise the Co-Detailing Option with respect to the first Licensed Product for which Janssen delivers top-line results in accordance with Section 5.6.2(c), then the Co-Detailing Option shall not apply to any future Licensed Products and this Section 5.6.2 shall become null and void. If Protagonist exercises the Co-Detailing Option with respect to two or more Licensed Products, Protagonist shall not have the right to provide more than thirty percent (30%) of the aggregate number of Details for all such Licensed Products nor more than thirty percent (30%) of the Details for any such Licensed Product. Notwithstanding the foregoing, Janssen shall have the right, upon [ * ] written notice where such Co-Detailing Option has not as of such time been exercised, or upon [ * ] written notice where such option has as of such time been exercised by Protagonist, to terminate the Co-Detailing Option and Protagonist’s rights under this Section 5.6.2 in the event of the occurrence of a Restricted Change of Control of Protagonist or an assignment of this Agreement in its entirety by Protagonist (other than an assignment to an Affiliate of Protagonist), unless Janssen otherwise consents, which consent may be withheld in Janssen’s sole discretion.

(c) Exercise of Option. Protagonist may, in its sole discretion, exercise the Co-Detailing Option with respect to a Licensed Product by delivering written notice thereof to Janssen (the “Co-Detailing Option Exercise Notice”) within [ * ] after receipt of written notice from Janssen that the top-line results of the second Phase 3 Clinical Trial of such Licensed Product for the initial Indication for which such event occurs have become available to Janssen if two Phase 3 Clinical Trials of such Licensed Product are conducted, and within [ * ] after receipt of written notice from Janssen that the top-line results of the first Phase 3 Clinical Trial of such Licensed Product have become available to Janssen if following the conduct of the first Phase 3 Clinical Trial Janssen determines in its reasonable discretion that a second Phase 3 Clinical Trial is not necessary to proceed with filing of a Drug Approval Application for such Licensed Product. Janssen shall provide such results to Protagonist promptly following the occurrence thereof.

(d) Co-Detailing Plan. If Protagonist provides a Co-Detailing Option Exercise Notice with respect to a Licensed Product, Janssen shall prepare and provide to Protagonist for its review and comment Janssen’s initial written plan for the Detailing of and allocation of calls for such Licensed Product in the U.S. (the “Initial Co-Detailing Plan”) in the ordinary course of its U.S. Commercialization planning process. The Parties shall discuss, and Janssen shall consider in good faith Protagonist’s comments on, the Initial Co-Detailing Plan before Janssen finalizes such plan. For clarity, this Section 5.6.2(d) does not limit or modify Janssen’s sole authority to Commercialize such Licensed Product pursuant to Section 5.6.1.

(e) Terms of Co-Detailing. Promptly following Janssen’s receipt of the Co-Detailing Option Exercise Notice for the first Licensed Product, the Parties shall negotiate in good faith to enter into a separate co-detailing agreement with respect to the co-detailing of such Licensed Product (and any additional Licensed Products for which Protagonist exercises the Co-Detailing Option) in the U.S. on commercially reasonable terms (the “Co-Detailing Agreement”), which would provide for a working group or other administrative body to be established by the Parties to serve solely as an information-sharing body with respect to each Party’s detailing activities, and not as an oversight or decision-making body. In addition to such usual and customary terms that are typically found within contract sales force agreements, the Co-Detailing Agreement shall include the terms set forth below in this Section 5.6.2(e).

(1) Protagonist would contribute a mutually agreed percentage of Janssen’s planned Details for each such Licensed Product in the U.S. for each Calendar Year (provided that such percentage shall not be less than [ * ] and shall not exceed thirty percent (30%) without Protagonist’s written consent), as set forth in Janssen’s call plan for such Calendar Year. Protagonist would employ a number of sales representatives sufficient to provide the agreed percentage of Details for each such Licensed Product in the U.S. for each Calendar Year.

(2) Following consultation through the working group or other administrative body established under the Co-Detailing Agreement, Janssen would have the right to allocate the planned Details for each such Licensed Product in the U.S. for each Calendar Year between the Parties in a manner consistent with the allocation described in clause (1) of this Section 5.6.2(e), provided that, unless the Parties agree otherwise, Protagonist would be allocated Details to healthcare professionals [ * ] for such Licensed Product in the U.S. The Parties would coordinate their detailing activities for such Licensed Products in the U.S. in accordance with mutually agreed procedures.

(3) Janssen would reimburse Protagonist for the Details of each such Licensed Product in the U.S. performed by Protagonist at a mutually agreed cost per primary detailing equivalent, which shall be agreed between the Parties acting reasonably and in good faith and [ * ].

(4) All Protagonist sales representatives who would Detail any Licensed Product in the U.S. would be required to [ * ] such Licensed Product in the U.S.

(5) Protagonist would compensate its sales representatives who detail each such Licensed Product in the U.S. using a sales compensation structure [ * ] such Licensed Product in the U.S.

(6) Each sales representative who details any Licensed Product in the U.S. on behalf of Protagonist would be required to [ * ].

(7) Protagonist’s sales representatives performing Details of a Licensed Product in the U.S. would be required to comply with Applicable Law and all of Janssen’s reasonable instructions, quality standards, policies and guidelines which relate to the Commercialization of such Licensed Product and of which Protagonist has been given sufficient written notice. Protagonist would establish a compliance program and appoint a compliance officer to ensure that Protagonist’s detailing of such Licensed Product is in compliance with Applicable Law and such Janssen instructions, quality standards, policies and guidelines. Janssen would have the right to audit Protagonist’s records regarding performance under the Co-Detailing Agreement, solely for the purpose of determining Protagonist’s compliance with the Co-Detailing Agreement.

(8) Janssen would have the right to terminate the Co-Detailing Agreement immediately by written notice if (i) Protagonist fails to contribute at least [ * ] percent ([ * ]%) of the Details for such Licensed Products in the U.S. for a Calendar Quarter that Protagonist is obligated to provide under the Co-Detailing Agreement and fails to remedy such shortfall within [ * ] after receiving written notice of such shortfall from Janssen or (ii) Protagonist materially breaches the Co-Detailing Agreement and fails to cure such breach within [ * ] after receiving written notice of such breach from Janssen. The Co-Detailing Agreement would be subordinate to and coterminous with this Agreement.

(9) The Co-Detailing Agreement would not be assignable by Protagonist without the consent of Janssen, which consent shall not be unreasonably withheld, conditioned, or delayed with respect to assignment to an Affiliate of Protagonist. The Co-Detailing Agreement would terminate in the event of the occurrence of a Restricted Change of Control

of Protagonist if Janssen terminates Protagonist’s rights as set forth in Section 5.6.2(b).

(10) Protagonist would have the right to terminate its obligations under the Co-Detailing Agreement on a Licensed Product-by-Licensed Product basis upon [ * ] prior written notice (or sooner, at Janssen’s election).

7.5. Royalties.

7.5.1. Royalty Rates. In partial consideration of the licenses and rights granted by Protagonist to Janssen under this Agreement, Janssen shall pay to Protagonist royalties on the aggregate Net Sales of each Licensed Product by Janssen, its Affiliates and sublicensees in each country in the Territory during each Calendar Year of the Royalty Term for such Licensed Product in such country at the rates set forth in the table below.

Annual Aggregate Net Sales of such Licensed Product in the Territory	Royalty Rate
For that portion of annual Net Sales of such Licensed Product in the Territory in such Calendar Year less than [ * ] Dollars (US$[ * ])	10	%
For that portion of annual Net Sales of such Licensed Product in the Territory in such Calendar Year greater than or equal to [ * ] Dollars (US$[ * ]) and less than [ * ] Dollars (US$[ * ])	[ * ]	%
For that portion of annual Net Sales of such Licensed Product in the Territory in such Calendar Year greater than or equal to [ * ] Dollars (US$[ * ])	[ * ]	%

By way of example, if annual Net Sales of a Licensed Product in the Territory during such Calendar Year were $[ * ], the royalties due with respect to such Licensed Product would equal the sum of (a) 10% of [ * ], (b) [ * ] and (c) [ * ].

7.5.2. Royalty Reductions.

(a) Janssen shall have the right to deduct, from the royalties due to Protagonist pursuant to Section 7.5.1 with respect to a Licensed Product during a Calendar Quarter, [ * ] percent ([ * ]%) of the aggregate payments made by Janssen or its Affiliate or sublicensee to such Third Party(ies) that are specifically made as consideration for a license under Third Party Blocking Intellectual Property Rights with respect to such Licensed Product during such Calendar Quarter, provided that if any agreement with such Third Party includes rights to additional intellectual property other than such intellectual property rights or covers products other than such Licensed Product, any such payment shall be equitably allocated by Janssen in good faith among all products and programs to which such agreement applies. Janssen shall provide documentation of such allocation to Protagonist, and any dispute regarding such allocation shall be subject to resolution under Article 13.

(b) On a country-by-country and Licensed Product-by-Licensed Product basis, the royalties due to Protagonist pursuant to Section 7.5.1 shall be reduced during the Royalty Term for such Licensed Product in such country to [ * ] percent ([ * ]%) of the amount otherwise payable from and after the date that there is no Valid Claim of any Protagonist Patent Right that Covers the composition of matter of such Licensed Product in such country. Such reduced royalty rate will be applied to the sales of the applicable Licensed Product beginning with the Calendar Quarter immediately following the Calendar Quarter during which such event first

occurs and will remain in effect unless and until the event set forth in Section 7.5.2(c).

(c) If, after the date upon which there is no Valid Claim of any Protagonist Patent Right that Covers the composition of matter of a Licensed Product sold by Janssen (directly or through an Affiliate or Third Party sublicensee) in a particular country, one or more Generic Products is sold by a Third Party in such country, the royalty rates provided in Section 7.5.1 for such Licensed Product shall be reduced in such country by [ * ] percent ([ * ]%) for the remainder of the Royalty Term for such Licensed Product in such country.

(d) Notwithstanding the foregoing, in no event shall the total deductions under Sections 7.5.2(a), 7.5.2(b), and 7.5.2(c) reduce the royalties payable to Protagonist under Section 7.5.1 with respect to a given Licensed Product in a given country in any Calendar Quarter by more than [ * ] percent ([ * ]%); provided, however, that to the extent Janssen cannot deduct any amounts because of this Section 7.5.2(d), Janssen may deduct such amounts from royalties payable in future Calendar Quarters, subject to this Section 7.5.2(d).

7.5.3. Royalty Term Expiration. Upon the expiration of the Royalty Term with respect to a Licensed Product in a country in the Territory, Protagonist hereby grants to Janssen a perpetual, irrevocable, non-exclusive, fully-paid and royalty-free right and license, with the right to grant sublicenses, under the Protagonist Intellectual Property to Develop, make, have made, use, have used, sell, have sold, offer for sale, have offered for sale, import, have imported, and otherwise exploit, Manufacture and Commercialize such Licensed Product in the Field in such country. For clarity, after the Royalty Term expires with respect to a Licensed Product in a country, the calculation of annual Net Sales of such Licensed Product in the Territory shall exclude sales of such Licensed Product in such country.

7.5.4. Royalty Reports and Payments. Commencing with the First Commercial Sale of a Licensed Product by Janssen or its Affiliates or sublicensees, (a) within [ * ] after the end of each Calendar Quarter, Janssen shall make preliminary written reports to Protagonist stating in each such report, by Licensed Product, the estimated aggregate Net Sales in U.S. Dollars of Licensed Products sold in the Territory during such Calendar Quarter by Janssen and its Affiliates and sublicensees, and (b) within [ * ] after the end of each Calendar Quarter Janssen shall make final written reports to Protagonist stating in each such report, by Licensed Product and by region (which regions shall be the U.S., Canada, Japan, the Major European Countries and all other countries in the Territory), the aggregate Net Sales in U.S. Dollars of Licensed Products sold during such Calendar Quarter by Janssen and its Affiliates and sublicensees. The final report shall also show (a) the calculation of the royalty payments due to Protagonist on such Net Sales ([ * ]), (b) the amount of taxes, if any, withheld to comply with Applicable Laws, and (c) the exchange rates used in calculating the payments due Protagonist, which exchange rates shall comply with Section 7.6.2. Simultaneously with the delivery of each such final

report, Janssen shall pay to Protagonist the total royalties, if any, due to Protagonist for the period of such report. If no royalties are due, Janssen shall so report. All preliminary and final reports delivered by Janssen under this Section 7.5.4 shall be Confidential Information of Janssen.

7.5.5. Royalty Conditions. All royalties due to Protagonist pursuant to Section 7.5.1 are subject to the following conditions: (a) only one royalty shall be due with respect to the same unit of Licensed Product; (b) no royalties shall be due upon the sale or other transfer among Janssen or its Affiliates, but in such cases the royalty shall be due and calculated upon Janssen’s or its Affiliate’s Net Sales to the first independent Third Party, and distributors of Janssen selling Licensed Product that are not Affiliates of Janssen will not, for this purpose, be deemed to be sublicensees of Janssen and shall instead be considered as independent Third Parties; and (c) no royalties shall be due upon free samples, donations, patient assistance, test marketing programs or other similar programs or studies.

7.6. Payment Terms.

7.6.1. Payments. All payments due under this Agreement shall be made in U.S. Dollars by wire transfer in immediately available funds to an account designated by the receiving Party or by other mutually acceptable means.

7.7.2. Each Party shall retain its Cost Records and Royalty Records for at least [ * ] following the end of the Calendar Year to which they pertain. Each Party shall, and shall cause its Affiliates and (sub)licensees to, make the Cost Records and Royalty Records available for inspection by an independent public accounting firm of national prominence

selected by the other Party, and reasonably acceptable to the audited Party, during normal business hours, as may be reasonably necessary for the sole purpose of verifying the cost and royalty reports and payments delivered by the Parties pursuant to Sections 7.2, 7.4 and 7.5 during the preceding [ * ]. The records for a given Calendar Year shall be subject to audit no more than [ * ]. Such independent public accounting firm shall execute a reasonable confidentiality agreement with the audited Party prior to commencing any such inspection. Such inspections shall be made no more than [ * ] at reasonable times and on reasonable notice.

7.7.3. Following completion of an inspection pursuant to Section 7.7.2, the independent public accounting firm shall, prior to distribution to the auditing Party, share its report with the audited Party. If the audited Party provides the independent public accounting firm with justifying remarks for inclusion in the report, the independent public accounting firm shall incorporate such remarks into its report prior to sharing the conclusions of such independent public accounting firm with the auditing Party. The final audit report shall be shared with both Parties at the same time and shall specify (a) whether any royalties paid by the audited Party during the audited period were correct and, if incorrect, the amount of any underpayment or overpayment and (b) whether any Phase 2 Development Costs or Collaboration CMC Costs reported by the audited Party during the audited period were correct and, if incorrect, the difference between the reported amounts and the amounts actually incurred. The audit report shall only contain the information relevant to support the statement as to whether the royalties paid or costs reported to the auditing Party were calculated accurately and shall not include any confidential information (or additional information that is ordinarily not included in the royalty or cost reports delivered pursuant to this Agreement) disclosed to the independent public accounting firm during the course of the audit.

7.7.4. The auditing Party shall bear the costs and expenses of any inspection conducted under this Section 7.7 unless such inspection reveals (a) an over-reporting of Phase 2 Development Costs and/or Collaboration CMC Costs by the audited Party of more than [ * ] percent ([ * ]%) of the actual Phase 2 Development Costs or Collaboration CMC Costs, as applicable, incurred by the audited Party during the audited period or (b) an underpayment of royalties payable pursuant to Section 7.5 by the audited Party of more than [ * ] percent ([ * ]%) of the amount payable for the audited period, in which case ((a) or (b)) the audited Party shall bear the costs and expenses of such inspection.

7.7.5. If such inspection reveals an over-reporting of Phase 2 Development Costs and/or Collaboration CMC Costs by the audited Party pursuant to Section 7.2, then the auditing Party shall conduct the applicable calculation pursuant to Section 7.2.3 and invoice the audited Party for the difference between the amount paid pursuant to Section 7.2.3 and the amount due as a result of the corrected calculation. The audited Party shall pay such invoice within [ * ] after receipt thereof.

7.7.6. If such inspection reveals an overpayment of royalties by the audited Party pursuant to Section 7.5, then the audited Party shall invoice the auditing Party for the

amount of the overpayment and the auditing Party shall pay such invoice within [ * ] after receipt thereof, provided that the auditing Party may elect to offset such amounts against future royalties payable by the audited Party. If such inspection reveals an underpayment of royalties by the audited Party pursuant to Section 7.5, then the auditing Party shall invoice the audited Party for the amount of the underpayment and the audited Party shall pay such invoice within [ * ] after receipt thereof.

7.7.7. If the audited Party disagrees with the findings of the audit report, the Parties will meet to attempt to mutually agree upon a resolution to the dispute. If such resolution cannot be reached, such disagreement shall be subject to the dispute resolution procedures set forth in Article 13.

7.8. Taxes.

7.8.1. Each Party shall make all payments under this Agreement without deduction or withholding for Taxes except to the extent that any such deduction or withholding is required by law in effect at the time of payment; provided, however, that the paying Party shall use reasonable, good faith efforts to give the recipient Party advance notice of its intention to make such deduction or withholding. Any Tax required to be withheld on amounts payable under this Agreement will be timely paid by the paying Party on behalf of the recipient Party to the appropriate Governmental Authority, and the paying Party will furnish the recipient Party with proof of payment of such Tax as well as any official receipts issued by the applicable Governmental Authority or other evidence as is reasonably requested to establish that such Taxes have been paid.

The Parties shall cooperate with each other in any defense of any such suit, action or proceeding. The Parties shall give each other prompt written notice of the commencement of any such suit, action or proceeding, or receipt of any claim of infringement, and shall furnish each other a copy of each communication relating to the alleged infringement.

8.7.2. Neither Party shall compromise, litigate, settle or otherwise dispose of any such suit, action or proceeding without the other Party’s advice and prior consent, provided

that the Party not having the right to defend the suit shall not unreasonably withhold or delay its consent to any settlement which does not have a material adverse effect on its rights, obligations or benefits, either under this Agreement or otherwise. Notwithstanding the foregoing, Janssen may seek to obtain a license from the applicable Third Party at its sole cost and expense (subject to the provisions of Section 8.10), provided that the terms and conditions of such license do not include an admission of invalidity of any Protagonist Patent Rights or Joint Collaboration Patent Rights, or restrict the other Party’s ability to challenge or litigate the validity or applicability of any intellectual property to which the license relates.

8.10. Third Party In-Licenses.

8.10.1.

In the event Janssen makes any such payment to a Third Party, Protagonist shall reimburse Janssen for such amount.

8.10.2. Prior to the Opt-In Effective Date, neither Party shall obtain a license from a Third Party under any Third Party Blocking Intellectual Property Rights without first (i) discussing the proposed license with the other Party, (ii) obtaining the consent of the other Party, (such consent not to be unreasonably withheld, conditioned, or delayed), and (iii) if applicable, agreeing upon the allocation of any royalties or other consideration payable to such Third Party between those related to the use of such Third Party Blocking Intellectual Property Rights for Licensed Compounds or Licensed Products under this Agreement and those related to the use of such Third Party Blocking Intellectual Property

Rights for any other products covered by such license. Such royalties and other consideration allocable to Licensed Compounds and Licensed Products will, unless otherwise agreed by the Parties, be shared in accordance with the principles set forth in Section 7.2 during the Development Term and be subject to the royalty reduction provisions set forth in Section 7.5.2(a) during the License Term. For the avoidance of doubt, any rights or licenses which a Party obtains under Third Party Blocking Intellectual Property Rights as a result of a merger with or acquisition of a Third Party who had prior to such transaction obtained such Third Party Blocking Intellectual Property Rights shall not be deemed a violation of this Section 8.10.2.

8.10.3. On and after the Opt-In Effective Date, if Janssen or its Affiliate or sublicensee is required, or [ * ] it necessary for Janssen or one of its Affiliates or sublicensees, to obtain a license from a Third Party under any Third Party Blocking Intellectual Property Rights in a country, Janssen (or its Affiliate or sublicensee) shall have the sole right to obtain such license. Such royalties and other consideration allocable to Licensed Compounds and Licensed Products will, unless otherwise agreed by the Parties, be subject to the royalty reduction provisions set forth in Section 7.5.2(a) during the License Term. On and after the Opt-In Effective Date, Protagonist shall not obtain a license from a Third Party under any Third Party Blocking Intellectual Property Rights without Janssen’s prior written consent. For the avoidance of doubt, any rights or licenses which Protagonist obtains under Third Party Blocking Intellectual Property Rights as a result of a merger with or acquisition of a Third Party who had prior to such transaction obtained such Third Party Blocking Intellectual Property Rights shall not be deemed a violation of this Section 8.10.3.

8.10.4. To the extent (a) Protagonist obtains a license from a Third Party after the Execution Date under any Know-How or Patent Rights that (i) fall within the definition of Protagonist Know-How or Protagonist Patent Rights and (ii) are not Third Party Blocking Intellectual Property Rights and (b) the sublicensing of such Know-How or Patent Rights hereunder to Janssen triggers payments to such Third Party under such license agreement, they shall not be automatically sublicensed to Janssen hereunder as Protagonist Know-How or Protagonist Patent Patents unless and until Janssen and Protagonist agree on the appropriate allocation of any royalties or other consideration payable to such Third Party between those related to the use of such Know-How or Patent Rights for Licensed Compounds or Licensed Products under this Agreement and those related to the use of such Know-How or Patent Rights for any other products covered by such license. Such royalties and other consideration allocable to Licensed Compounds and Licensed Products will, unless otherwise agreed by the Parties, be shared in accordance with the principles set forth in Section 7.2 during the Development Term.

To the extent either Party discloses to the other Party any Confidential Information which is a fact, result or event relating to the Development or Commercialization of any Licensed Compound or Licensed Product or the Collaboration Activities that the receiving Party in good faith reasonably believes is insufficient to allow the receiving Party to fully understand the materiality of such Confidential Information for purposes of determining whether the receiving Party is required to disclose, to any Governmental Authority or publicly, any such Confidential Information in order to comply with Applicable Law (including securities laws or regulations and the applicable rules of any public stock exchange), the Disclosing Party agrees to discuss such Confidential Information with the Receiving Party to enable the Receiving Party to assess the materiality of such information for such public disclosure purposes.

9.8. Equitable Relief.

Either Party may make oral or written publications (such as any abstracts, manuscripts, posters, slide presentations or other materials) of any activities or results relating to a Licensed Compound or Licensed Product, provided that (a) Janssen shall not have such right until after the Opt-In Effective Date, except with Protagonist’s prior written consent, which consent will not be unreasonably withheld, (b) the other Party shall first have the right to review and comment on a draft of any such material proposed for publication by such Party, including for purposes of ensuring that none of its Confidential Information is disclosed without its consent, and (c) such Party may not include any Confidential Information of the other Party in such publication without the other Party’s prior written consent, which consent will not be unreasonably withheld. The publishing Party shall deliver a complete draft to the other Party at least [ * ] ([ * ] in the case of abstracts) prior to submitting the material to a publisher or initiating any other release. The non-publishing Party shall review any such material and give its comments to the publishing Party within [ * ] ([ * ] in the case of abstracts) after the delivery of such draft to the non-publishing Party, and the publishing Party shall consider such comments in good faith. The publishing Party shall comply with the non-publishing Party’s request to: delete from any such proposed publication material prior to its submission or release any references to the non-publishing Party or any of its Confidential Information; or delay any submission or release for a period of up to an additional [ * ] to permit the non-publishing Party to prepare and file, or have prepared and filed, any patent applications for any Collaboration Inventions as contemplated hereunder.

disclosures required by Applicable Laws or the rules of the United States Securities and Exchange Commission or the Nasdaq Stock Market or similar security regulatory authorities or stock markets in other countries, as applicable, which are governed by Sections 9.4 and 9.5.

9.10. Attorney-Client Privilege. Neither Party is waiving, nor shall be deemed to have waived or diminished, any of its attorney work product protections, attorney-client privileges or similar protections and privileges as a result of disclosing information pursuant to this Agreement (including Confidential Information related to pending or threatened litigation) to the Receiving Party, regardless of whether the Disclosing Party has asserted, or is or may be entitled to assert, such privileges and protections. The Parties: (a) share a common legal and commercial interest in such disclosure that is subject to such privileges and protections; (b) are or may become joint defendants in proceedings to which the information covered by such protections and privileges relates; (c) intend that such privileges and protections remain intact should either Party become subject to any actual or threatened proceeding to which the Disclosing Party’s Confidential Information covered by such protections and privileges relates; and (d) intend that after the Execution Date both the Receiving Party and the Disclosing Party shall have the right to assert such protections and privileges.

Subject to Section 11.2, Janssen shall defend, indemnify and hold harmless Protagonist and each of its Affiliates, and each of its and their directors, officers, employees and agents (each, a “Protagonist Indemnified Party”) from and against any and all damages, losses, liabilities, judgments, fines, amounts paid in settlement, costs and expenses (including the reasonable costs and expenses of attorneys and other professionals) (collectively, “Losses”) incurred by any Protagonist Indemnified Party resulting from any claim, action or proceeding brought or initiated by a Third Party (“Third Party Claim”) against a Protagonist Indemnified Party, to the extent that such Losses arise out of or relate to, directly or indirectly:

(a) the breach by Janssen of any of its representations, warranties, covenants, or obligations set forth herein;

(b) the negligence, recklessness or wrongful intentional acts or omissions of any Janssen Indemnified Party; or

(c) the Development, Manufacture or Commercialization of any Licensed Compound or Licensed Product by or on behalf of Janssen or any of its Affiliates on or after the Effective Date and during the Term (or any post-termination or post-expiration period pursuant to Section 12.6);

except, in each case ((a) through (c)), to the extent such Losses arise directly or indirectly from (i) the breach by Protagonist of any of its representations, warranties, covenants, or obligations set forth herein, (ii) the negligence, recklessness or wrongful intentional acts or omissions of any Protagonist Indemnified Party, or (iii) the Development, Manufacture or Commercialization of any Licensed Compound or Licensed Product by or on behalf of Protagonist or any of its Affiliates prior to the Effective Date or during any post-termination or post-expiration period pursuant to Section 12.6.

11.1.2. Indemnification by Protagonist. Subject to Section 11.2, Protagonist shall defend, indemnify and hold harmless Janssen and each of its Affiliates, and each of its and their directors, officers, employees and agents (each, a “Janssen Indemnified Party”), from and against any and all Losses incurred by any Janssen Indemnified Party resulting from any Third Party Claim against a Janssen Indemnified Party, to the extent that such Losses arise out of or relate to, directly or indirectly:

(a) the breach by Protagonist of any of its representations, warranties, or covenants or obligations set forth herein; and

(c) the Development, Manufacture or Commercialization of any Licensed Compound or Licensed Product by or on behalf of Protagonist or any of its Affiliates prior to the Effective Date or during any post-termination or post-expiration period pursuant to Section 12.6, or the Development or Manufacture of any Licensed Compound or Licensed Product by or on behalf of Protagonist or any of its Affiliates during the Development Term; or

(d) the research, development, manufacture or commercialization of any Retained Compound by or on behalf of Protagonist or any of its Affiliates.

except, in each case ((a) through (d)), to the extent such Losses arise directly or indirectly from (i) the breach by Janssen of any of its representations, warranties, covenants, or obligations set forth herein, (ii) the negligence, recklessness or wrongful intentional acts or omissions of any Janssen Indemnified Party, or (iii) the Development, Manufacture or Commercialization of any Licensed Compound or Licensed Product by or on behalf of Janssen or any of its Affiliates on or after the Effective Date and during the Term (or any post-termination or post-expiration period pursuant to Section 12.6).

11.2. Conditions to Indemnification. If either a Janssen Indemnified Party or a Protagonist Indemnified Party (each, an “Indemnified Party”) intends to seek indemnification under Section 11.1, the Indemnified Party must: (a) give the other Party (the “Indemnifying Party”) reasonably prompt written notice upon becoming aware of any Third Party Claim with respect to which such Indemnified Party intends to seek indemnification; (b) reasonably cooperate with the Indemnifying Party at the Indemnifying Party’s request and expense, in the defense or settlement of the claim; and (c) give the Indemnifying Party the right to control the defense or settlement of the claim, provided that the Indemnifying Party will not enter into any settlement that adversely affects the Indemnified Party’s rights or obligations without the Indemnified Party’s prior express written consent, which will not be unreasonably withheld, conditioned or delayed. The Indemnified Party may participate in the defense or settlement of any such claim at its own expense with counsel of its choosing. Notwithstanding the foregoing, any failure of the Indemnified Party to comply with the provisions of clause (a) of this Section 11.2 will not relieve the Indemnifying Party of any defense or indemnity obligations under this Agreement except to the extent that the Indemnifying Party is prejudiced by such failure. So long as the Indemnifying Party is actively defending such Third Party Claim in good faith, the Indemnified Party shall not settle any such claim without the prior written consent of the Indemnifying Party. If the Indemnifying Party does not assume and conduct the defense of the claim as provided above, (i) the Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to the claim in any manner the Indemnified Party may deem reasonably appropriate (and the Indemnified Party need not consult with, or obtain any consent from, the Indemnifying Party in connection therewith), and (ii) the Indemnifying Party will remain responsible to indemnify the Indemnified Party as provided in this Article 11.

11.3. LIMITATIONS OF LIABILITY. EXCEPT TO THE EXTENT INCLUDED IN LOSSES RESULTING FROM A THIRD PARTY CLAIM FOR WHICH ONE PARTY IS OBLIGATED TO INDEMNIFY THE OTHER PARTY (OR AN INDEMNIFIED PARTY OF

SUCH OTHER PARTY) PURSUANT TO THIS Article 11 OR ANY BREACH OF Article 9 (CONFIDENTIALITY), IN NO EVENT WILL EITHER PARTY BE LIABLE TO THE OTHER PARTY (OR THE OTHER PARTY’S AFFILIATES OR (SUB)LICENSEES) IN CONNECTION WITH THIS AGREEMENT FOR ANY CONSEQUENTIAL, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE OR INDIRECT DAMAGES UNDER ANY THEORY (INCLUDING FOR LOST PROFITS, LOST REVENUE, LOST SAVINGS, LOSS OF USE OR DAMAGE TO GOODWILL TO THE EXTENT THEY CONSTITUTE CONSEQUENTIAL, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE OR INDIRECT DAMAGES DAMAGES), INCLUDING CONTRACT, NEGLIGENCE, OR STRICT LIABILITY, EVEN IF THAT PARTY HAS BEEN PLACED ON NOTICE OF THE POSSIBILITY OF SUCH DAMAGES.

11.4. Insurance. Each Party shall, at its own expense, procure and maintain during the Term and for a period of five (5) years thereafter, insurance policies, including product liability insurance, adequate to cover the activities to be conducted by it and its obligations under this Agreement and which are consistent with normal business practices of prudent companies similarly situated; provided, however, that in no event shall such product liability insurance be written in amounts less than USD $[ * ] per claim or per occurrence and annual aggregate. All such insurance shall include worldwide coverage. Prior to the initiation of any clinical trial of a Licensed Compound or Licensed Product, the Party responsible for such clinical trial shall secure, and maintain in full force and effect, clinical trial insurance as required by applicable Law in those territories where such clinical trial shall be conducted. Upon request, each Party shall provide the other Party with a certificate of insurance evidencing the coverage required under this Section 11.4. Such insurance shall not be construed to create a limit of a Party’s liability with respect to its obligations under this Agreement. Each Party shall provide the other Party with prompt written notice of cancellation, non-renewal or material change in such insurance that could materially adversely affect the rights of such other Party hereunder, and shall provide such notice within [ * ] after any such cancellation, non-renewal or material change. Notwithstanding the foregoing, either Party’s failure to maintain adequate insurance shall not relieve that Party of its obligations set forth in this Agreement. The Parties acknowledge and agree that Janssen may meet its obligations under this Section 11.4 through self-insurance consistent with the levels set forth herein with prior written notice to Protagonist. In such event, Janssen shall provide a written certification of such self-insurance to Protagonist from upon request.

Article 12
TERM AND TERMINATION

12.1. Term. The term of this Agreement (the “Term”) will commence on the Execution Date and, unless this Agreement is terminated earlier in accordance with Section 4.1.4, Section 4.2.4 or this Article 12, will expire upon expiration of all of the payment obligations under Article 7 with respect to Licensed Products Developed and/or Commercialized by Janssen pursuant to this Agreement. The provisions of Article 1 (Definitions), Article 9 (Confidentiality; Publicity), Article 10 (Representations and Warranties), Article 13 (Dispute Resolution), and Article 14 (Miscellaneous), and Section 12.3 (Termination for Material Breach) and Section 12.5 (HSR

Filing; Termination Upon HSR Denial), shall become effective on the Execution Date; the other provisions of this Agreement shall not become effective until the Effective Date.

12.2. Termination by Janssen Without Cause. Janssen may terminate this Agreement in its entirety at any time without cause by providing [ * ] prior written notice to Protagonist.

12.3. Termination for Material Breach.

12.3.1. A Party (the “Terminating Party”) may terminate this Agreement in its entirety if the other Party (the “Breaching Party”) has materially breached this Agreement and such material breach has not been cured within [ * ] (or, if the basis of such material breach is failure to make payment, [ * ], other than payment of the Opt-In Maintenance Fee, which shall be addressed as set forth in Section 4.1.4(b), and other than payment of the Opt-In Exercise Fee, which shall be addressed as set forth in Section 4.2.4(b)) after written notice of such breach is given by the Terminating Party to the Breaching Party (the “Cure Period”). The written notice describing the alleged material breach shall provide sufficient detail to put the Breaching Party on notice of such material breach. Any termination of this Agreement pursuant to this Section 12.3.1 shall become effective at the end of the Cure Period unless the Breaching Party has cured any such material breach prior to the expiration of such Cure Period. Notwithstanding the foregoing, if such breach (other than a breach of payment obligations) is capable of being cured but is not reasonably able to be cured within the Cure Period, such termination shall not become effective until the earlier of the date such breach is cured or [ * ] after notice of termination is given pursuant to this Section 12.3.1, provided that (a) the Breaching Party notifies the other Party of its plan for curing such breach during the Cure Period, (b) the Breaching Party commences such plan during the Cure Period and (c) the Breaching Party uses diligent efforts to perform such plan and cure such breach as soon as reasonably practicable). The right of either Party to terminate this Agreement as provided in this Section 12.3.1 shall not be affected in any way by such Party’s waiver of or failure to take action with respect to any previous breach under this Agreement.

12.3.2. If the Parties reasonably and in good faith disagree as to whether there has been a material breach or a cure thereof, the Party that disputes whether there has been a material breach or a cure may contest the allegation in accordance with Article 13. Notwithstanding anything to the contrary contained in Section 12.3.1, the Cure Period for any material breach that is the subject of a Dispute will run from the date that written notice was first given to the Breaching Party by the Terminating Party through the resolution of such Dispute pursuant to Article 13 and for [ * ] thereafter, and no termination pursuant to Section 12.3.1 shall become effective during such period. During the pendency of such Dispute, all of the terms and conditions of this Agreement shall remain in effect and the Parties shall continue to perform all of their respective obligations hereunder; provided that the Parties’ performance of their respective obligations and exercise of their respective rights hereunder that specify a date by which such obligations must be performed or such rights must be exercised shall be tolled through the resolution of such Dispute pursuant to Article 13 and for 10 days thereafter.

12.4. Termination for Bankruptcy.

12.4.1. Right to Terminate. A Party may terminate this Agreement in its entirety upon providing written notice to the other Party on or after the time that such other Party makes a general assignment for the benefit of creditors, files a voluntary petition in bankruptcy, consents to an order for relief in connection with an involuntary petition in bankruptcy filed against such Party (or an involuntary petition in bankruptcy filed against such Party remains un-dismissed or un-stayed for a period of more than [ * ]), petitions for or acquiesces in the appointment of any receiver, trustee or similar officer to liquidate or conserve its business or any substantial part of its assets, commences under the laws of any jurisdiction any proceeding involving its insolvency, bankruptcy, reorganization, adjustment of debt, dissolution, liquidation or any other similar proceeding for the release of financially distressed debtors, or becomes a party to any proceeding or action of the type described above (each, an “Insolvency Event”).

12.4.2. Provisions for Insolvency.

(a) All rights and licenses now or hereafter granted by either Party to the other Party under or pursuant to this Agreement, including, for the avoidance of doubt, the licenses granted to Janssen pursuant to Section 6.1 are, for all purposes of Section 365(n) of Title 11 of the United States Code, as amended (such Title 11, the “Bankruptcy Code”)), licenses of rights to “intellectual property” as defined in the Bankruptcy Code. Upon the occurrence of any Insolvency Event with respect to a Party, such Party agrees that the other Party, as licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under the Bankruptcy Code.

(b) Without limiting the generality of the foregoing, Protagonist and Janssen intend and agree that any sale of the Protagonist Intellectual Property licensed hereunder under Section 363 of the Bankruptcy Code shall be subject to Janssen’s rights under Section 365(n), that Janssen cannot be compelled to accept a money satisfaction of its interests in the intellectual property licensed pursuant to this Agreement, and that any such sale therefore may not be made to a purchaser “free and clear” of Janssen’s rights under this Agreement and Section 365(n) without the express, contemporaneous consent of Janssen. Further, each Party agrees and acknowledges that all payments by Janssen to Protagonist hereunder, other than the Opt-In Maintenance Fee, Opt-In Exercise Fee, the royalty payments pursuant to Section 7.5, the Milestone Payments pursuant to Section 7.3 and the Sales Milestone Payments pursuant to Section 7.4, the allocation of recoveries under Section 8.5.6 and reimbursements for amounts paid under Third Party Blocking Intellectual Property Rights licenses pursuant to Section 8.10, do not constitute royalties within the meaning of Section 365(n) of the Bankruptcy Code or relate to licenses of intellectual property hereunder.

(c) Protagonist shall, during the Term, create and maintain current copies or, if not amenable to copying, detailed descriptions or other appropriate

embodiments, to the extent feasible, of all Protagonist Intellectual Property licensed hereunder, in accordance with Section 3.6.3. Protagonist and Janssen acknowledge and agree that “embodiments” of intellectual property within the meaning of Section 365(n) include [ * ]. The Parties further agree that, in the event of the commencement of a bankruptcy proceeding by or against Protagonist under the Bankruptcy Code and any similar laws in any other country in the Territory, Janssen will be entitled to a complete duplicate of (or complete access to, as appropriate) any such intellectual property and all embodiments of such intellectual property, and the same, if not already in Janssen’s or its Affiliates’ possession, will be promptly delivered to it (i) upon any such commencement of a bankruptcy proceeding upon its written request therefor, unless Protagonist elects to continue to perform all of its obligations under this Agreement, or (ii) if not delivered under (i) above, following the rejection of this Agreement by or on behalf of Protagonist upon written request therefor by Janssen. Whenever Protagonist or any of its successors or assigns provides to Janssen any of the intellectual property licensed hereunder (or any embodiment thereof) pursuant to this Section 12.4.2, Janssen shall have the right to perform Protagonist’s obligations hereunder with respect to such intellectual property, but neither such provision nor such performance by Janssen shall release Protagonist from liability resulting from rejection of the license or the failure to perform such obligations. Protagonist (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee) shall not interfere with Janssen’s rights under this Agreement, or any agreement supplemental hereto, to such intellectual property (including such embodiments), including any right to obtain such intellectual property (or such embodiments) from another entity, to the extent provided in Section 365(n) of the Bankruptcy Code.

(d) All rights, powers and remedies of Janssen provided herein are in addition to and not in substitution for any and all other rights, powers and remedies now or hereafter existing at law or in equity (including the Bankruptcy Code) in the event of the commencement of a case under the Bankruptcy Code with respect to Protagonist. The Parties agree that they intend the following rights to extend to the maximum extent permitted by law, and to be enforceable under Bankruptcy Code Section 365(n):

(1) the right of access to any intellectual property (including all embodiments thereof) of Protagonist licensed to Janssen pursuant to Section 6.1, or any Third Party with whom Protagonist contracts to perform an obligation of Protagonist under this Agreement, and, in the case of the Third Party, which is necessary for the manufacture, use, sale, import or export of Licensed Compounds and Licensed Products; and

(2) the right to contract directly with any Third Party to complete the contracted work.

12.5. HSR Filing; Termination upon HSR Denial. If Janssen and Protagonist determine that an HSR Filing is necessary, each Party shall, within ten (10) Business Days of the Execution Date (or such later time as may be agreed to in writing by the Parties), file with the United States Federal Trade Commission and the Antitrust Division of the United States Department of Justice, and/or with equivalent foreign authorities, any HSR Filing required of it under the HSR Act or applicable antitrust or competition Laws of other jurisdictions in the reasonable opinion of either Party with respect to the transactions contemplated hereby. Neither Party shall seek expedited treatment of any HSR Filing without the other Party’s prior written consent. Each Party will use reasonable efforts to do, or cause to be done, all things necessary, proper and advisable to, as promptly as practicable, take all actions necessary to make the filings required of such Party or its Affiliates under the HSR Act. The Parties shall cooperate with one another to the extent necessary in the preparation of any such HSR Filing. Each Party shall be responsible for its own costs, expenses, and filing fees associated with any HSR Filing; provided, however, that Janssen shall be solely responsible for any fees (other than penalties that may be incurred as a result of actions or omissions on the part of Protagonist) required to be paid to any governmental agency in connection with making any such HSR Filing. If the Parties make an HSR Filing hereunder, then this Agreement shall terminate (a) at the election of either Party, immediately upon written notice to the other Party, if the U.S. Federal Trade Commission or the U.S. Department of Justice, or an equivalent authority in the European Union, seeks a preliminary injunction under the applicable Antitrust Laws against Janssen and Protagonist to enjoin the transactions contemplated by this Agreement; or (b) at the election of either Party, immediately upon written notice to the other Party, in the event that the HSR Clearance Date shall not have occurred on or prior to [ * ] after the effective date of the HSR Filing. In the event of such termination, this Agreement shall be of no further force and effect.

12.6. Effects of Termination or Expiration.

12.6.1. Effects of Termination. If this Agreement is terminated for any reason, then the provisions of this Section 12.6.1 shall apply.

(a) The licenses and other rights granted to Janssen under this Agreement, other than those that expressly survive termination of this Agreement (including the license granted pursuant to Section 6.1.3), shall terminate on the effective date of termination, except as expressly provided in Section 7.5.3 or to the extent necessary to enable Janssen to perform any of its obligations that survive termination.

(b) Janssen shall have no further obligation to commence new Development activities with respect to a Licensed Compound or Licensed Product after the date of notice of termination.

(c) If this Agreement is terminated by Janssen during the conduct of any Phase 2 Activities or Collaboration CMC Activities for the Phase 2 Activities, Protagonist shall have [ * ] after the date that Janssen notifies Protagonist of termination (or, in the event of termination pursuant to Section 4.1.4 or Section 4.2.4, the date of termination under Section 4.1.4 or Section 4.2.4, as applicable)

to notify Janssen (i) whether Protagonist elects to have Janssen complete or wind down any such on-going Phase 2 Activities and (ii) whether Protagonist elects to have Janssen wind down or transfer to Protagonist any such ongoing Collaboration CMC Activities. Notwithstanding the foregoing, if Janssen terminates this Agreement pursuant to Section 12.3 or 12.4, then Protagonist shall not have the right to make the election described in this paragraph and Janssen shall wind down any ongoing activities as soon as practicable after the date of notice of termination. The following provisions of this Section 12.6.1(c) shall apply after Protagonist makes such elections.

(1) If Protagonist elects to have Janssen wind down on-going Phase 2 Activities or Collaboration CMC Activities, then Janssen shall wind-down such Phase 2 Activities or Collaboration CMC Activities as soon as practicable, subject to compliance with ethical and legal requirements, and the Parties shall continue to share the costs of such activities in accordance with Section 7.2 until such wind-down is complete.

(2) If Protagonist elects to have Janssen complete on-going Phase 2 Activities, then (x) Janssen shall continue to conduct such Phase 2 Activities in accordance with Article 3, (y) the Parties shall continue to share the Phase 2 Development Costs for such activities in accordance with Section 7.2, except that [ * ] with respect to any Phase 2 Development Costs incurred after the effective date of termination and (z) Article 2, Article 3 (other than Sections 3.4.5 and 3.4.6), Section 4.2.1, Article 6 and Section 10.5 shall survive to the extent applicable to, or necessary to conduct, such Phase 2 Activities, until the Phase 2 Data Package is delivered by Janssen to Protagonist in accordance with Section 4.2.1.

(3) If Protagonist elects to have Janssen transfer to Protagonist on-going Collaboration CMC Activities, then Janssen shall use Commercially Reasonable Efforts to transfer, and Protagonist shall use Commercially Reasonable Efforts to assume, such activities as promptly as practicable (and, in any event, within [ * ] after the effective date of termination). The Parties shall continue to share the costs of such activities in accordance with Section 7.2 until the effective date of termination and, thereafter, the costs of such activities shall be borne solely by Protagonist; provided, however, that each Party shall bear its own costs associated with the transfer of such Collaboration CMC Activities from Janssen to Protagonist. Protagonist shall reimburse Janssen for any such costs for which Protagonist is solely responsible incurred by Janssen and its Affiliates after the effective date of termination.

(d) If this Agreement is terminated for any reason (other than by Janssen during the conduct of any Phase 2 Activities or Collaboration CMC Activities for

the Phase 2 Activities, in which case Section 12.6.1(c) shall apply) and Janssen is conducting any Development activity with respect to a Licensed Compound or Licensed Product on the date of notice of termination, then Protagonist shall notify Janssen within [ * ] after the notice of termination: (i) with regard to any Clinical Trial, whether Protagonist elects to have Janssen (A) complete such Clinical Trial on behalf of Protagonist (unless Janssen has material safety concerns regarding continuation of such Clinical Trial of which it has notified Protagonist in writing), (B) wind down such Clinical Trial as soon as practicable, subject to compliance with ethical and legal requirements or (C) transfer such Clinical Trial to Protagonist as soon as practicable; and (ii) with regard to any other Development activity, whether Protagonist elects to have Janssen wind down or transfer such activity to Protagonist. Notwithstanding the foregoing, if Janssen terminates this Agreement pursuant to Section 12.3 or 12.4, then Protagonist shall not have the right to make the election described in this paragraph and Janssen shall wind down any ongoing Development activities as soon as practicable after the date of notice of termination.

(1) If Protagonist notifies Janssen of its election to have Janssen complete a Clinical Trial on behalf of Protagonist, Janssen and Protagonist will negotiate in good faith a separate agreement pursuant to which Janssen would complete such Clinical Trial. If the Parties fail to reach agreement within [ * ] after Protagonist makes such election, Janssen may wind down such Clinical Trial.

(2) If Protagonist notifies Janssen of its election to have Janssen wind down such Clinical Trial or other Development activity (or fails to provide notice within such [ * ] period), then Janssen shall wind-down such Clinical Trial or Development activity as soon as practicable, subject to compliance with ethical and legal requirements.

(3) If Protagonist notifies Janssen of its election to have Janssen transfer such Clinical Trial or other Development activity to Protagonist, then Janssen shall use Commercially Reasonable Efforts to transfer, and Protagonist shall use Commercially Reasonable Efforts to assume, such Clinical Trial or other Development activity as promptly as practicable (and, in any event, within [ * ]) after the effective date of termination.

(4) The costs of any such Development activity (other than a Clinical Trial with respect to which the Parties enter into a separate agreement pursuant to Section 12.6.1(d)(1)) shall be borne solely by Janssen until the effective date of termination (or, with respect to the wind-down of a Clinical Trial, through the completion of such Clinical Trial), and thereafter shall be borne solely by Protagonist.

(5) Each Party shall bear its own costs associated with the transfer of any such Development activity from Janssen to Protagonist.

(e) Janssen shall, within [ * ] after the effective date of termination and at Janssen’s expense, return or destroy, at Protagonist’s election, all Protagonist Know-How and other Confidential Information of Protagonist (provided that (i) Janssen may keep one copy of such Confidential Information subject to an ongoing obligation of confidentiality for archival purposes only, (ii) it is acknowledged that, with regard to any such Confidential Information disclosed to subcontractors, consultants, agents, advisors and other Third Parties as permitted by Section 9.3, Janssen’s use of Commercially Reasonable Efforts to return or destroy such Confidential Information shall satisfy its obligation under this Section 12.6.1(e), and (iii) Janssen may retain and continue to use Protagonist Know-How and other Confidential Information of Protagonist solely to practice any licenses and other rights granted to Janssen under this Agreement that expressly survive expiration of this Agreement.

(f) Janssen shall, and hereby does, assign to Protagonist, as of the effective date of termination, all its right, title and interest in, to and under all of Janssen’s and its Affiliates’ ownership interest in any Regulatory Documentation solely related to the Licensed Compounds and Licensed Products, including any Regulatory Approvals for the Licensed Compounds and Licensed Products, and Janssen shall transfer all such Regulatory Documentation to Protagonist promptly after the effective date of termination.

(g) Janssen shall, and hereby does, grant to Protagonist, as of the effective date of termination, an exclusive, perpetual, royalty-free (except to the extent set forth in Section 12.6.2), freely sublicensable, transferable license under the Janssen Collaboration Know-How, Janssen Collaboration Patent Rights and Janssen’s interest in the Joint Collaboration Patent Rights solely to the extent necessary to Develop, make, have made, use, have used, sell, have sold, offer for sale, have offered for sale, import, have imported, and otherwise exploit, Manufacture and Commercialize Licensed Compounds and Licensed Products in the Field in the Territory.

(h) At Protagonist’s request, Janssen shall assign and transfer to Protagonist any inventory of Licensed Compounds or Licensed Products then in Janssen’s or any of its Affiliate’s possession or control subject to Protagonist’s reimbursement of Janssen’s reasonable, documented costs incurred in acquiring such inventory and with respect to shipping thereof.

(i) Subject to Section 6.1.3, all Collaboration Information as defined in subsections (a)-(d) of Section 1.20 that is licensed, assigned or transferred to Protagonist pursuant to this Section 12.6.1 shall be deemed to be Confidential Information of Protagonist for the purposes of Article 9 and Protagonist shall be deemed the Disclosing Party and Janssen shall be deemed the Receiving Party with respect to such information.

12.6.2. Post-Termination Royalties to Janssen. If Janssen delivers the Phase 2 Data Package in accordance with Section 4.2.1, and either (i) Janssen does not make the Second Opt-In Election or (ii) at any time after the Second Opt-In Election, Janssen terminates this Agreement pursuant to Section 12.2, Section 12.3 or Section 12.4, then, in exchange for the license granted by Janssen to Protagonist pursuant to Section 12.6.1(g), Protagonist shall be obligated to pay Janssen royalties in accordance with the rates set forth in the table below on Net Sales of Licensed Products containing the Initial Compound sold on or after the effective date of termination by Protagonist or any of its Affiliates or (sub)licensees.

For purposes of this Section 12.6.2, “Net Sales” shall have the meaning given to it in Section 1.69, as if the references to Janssen in such definition were to Protagonist.

12.6.3. Janssen Confidential Information. Protagonist shall, within [ * ] after the effective date of expiration or termination of this Agreement, and at Protagonist’s expense, return or destroy, at Janssen’s election, all Confidential Information of Janssen (provided that (i) Protagonist may keep one copy of such Confidential Information subject to an ongoing obligation of confidentiality for archival purposes only, (ii) it is acknowledged that, with regard to any such Confidential Information disclosed to subcontractors, consultants, agents, advisors and other Third Parties as permitted by Section 9.3, Protagonist’s use of Commercially Reasonable Efforts to return or destroy such Confidential Information shall satisfy its obligation under this Section 12.6.3, and

(iii) Protagonist may retain and continue to use Confidential Information of Janssen to practice any licenses and other rights granted to Protagonist under this Agreement that expressly survive expiration or termination of this Agreement).

12.6.4. Additional Effects of Expiration or Termination for any Reason. Termination or expiration of this Agreement will not relieve the Parties of any obligations accruing prior to such expiration or termination, and any such expiration or termination will be without prejudice to the rights of either Party accruing prior to such expiration or termination. The Parties acknowledge and agree that termination of this Agreement is not the sole remedy under this Agreement and, whether or not termination is effected, all other remedies will remain available except as expressly agreed to otherwise herein. The provisions of Sections 3.6.3(a), 6.1.3, 6.3.2 (3rd sentence only), 6.6, 7.2 (solely with respect to Phase 2 Development Costs and Phase 2 CMC Development Costs incurred prior to the effective date of expiration or termination), 7.5 (solely with respect to Net Sales occurring prior to the effective date of such expiration or termination), 7.6, 7.7, 7.8, 8.1, 8.2, 12.4.2(a) (solely with respect to the license granted pursuant to Section 6.1.3) and 12.6, and Articles 9, 11, 13, and 14 shall survive expiration or termination of this Agreement for any reason.

JANSSEN ENTERS INTO WORLDWIDE EXCLUSIVE LICENSE AND COLLABORATION AGREEMENT

WITH PROTAGONIST THERAPEUTICS INC. FOR ORAL INTERLEUKIN-23 RECEPTOR ANTAGONIST DRUG CANDIDATE FOR THE TREATMENT OF INFLAMMATORY BOWEL DISEASE

Long-standing relationship between Johnson & Johnson Innovation, Janssen and Protagonist Therapeutics leads to advancement of promising oral drug candidate for Crohn’s disease and ulcerative colitis

Horsham, Pa., May 30, 2017 –– Janssen Biotech, Inc., one of the Janssen Pharmaceutical Companies of Johnson & Johnson, announced today it has entered into a worldwide exclusive license and collaboration agreement with Protagonist Therapeutics, Inc. (Protagonist) to develop, manufacture and commercialize PTG-200, a first-in-class, oral interleukin (IL)-23 receptor antagonist drug candidate in development for the treatment of Crohn’s disease and ulcerative colitis (UC). Under the terms of the agreement and subject to the termination or expiration of any applicable waiting periods under the Hart-Scott-Rodino Act, Protagonist will receive an upfront payment and is eligible to receive development and commercialization milestone payments. If PTG-200 is commercialized, Protagonist would be eligible to receive royalties on net sales, and will also have the option to co-detail in the US. The agreement stems from a long-standing collaboration fostered through a series of equity investments by Johnson & Johnson Innovation — JJDC, Inc. in Protagonist to study and advance oral peptide-based therapeutics.

Inflammatory bowel disease (IBD), which includes Crohn’s disease and UC, affects five million people globally, and the incidence is growing with almost a three-time increase in the U.S. as recently reported by the Centers for Disease Control and Prevention12. In addition, many patients who receive treatment today do not achieve remission and approximately 80 percent of patients with Crohn’s disease and 30 percent of patients with UC will progress to surgery.3

“The addition of PTG-200 to the Janssen Immunology portfolio builds upon our expertise and leadership in the IL-23 pathway, and we look forward to advancing this novel oral IL-23 receptor antagonist into clinical development,” said Susan B.Dillon, PhD, Global Therapeutic Area Head, Immunology, Janssen. “Together with Johnson & Johnson Innovation, we have forged a strong relationship with the Protagonist Therapeutics team over the course of several years. We look forward to continuing a strong and productive collaboration in progressing this novel oral candidate for the treatment of inflammatory bowel disease.”

PTG-200, a potential first-in-class oral IL-23R antagonist, is currently in Investigational New Drug (IND) enabling studies and the initiation of a Phase 1 clinical trial is planned in 2017.

“We look to continue to pioneer the science of inflammatory bowel disease and advance novel therapeutics like PTG-200, an oral therapy that targets a validated pathway and acts locally in the gut at the site of disease,” said Scott E. Plevy, MD, Disease Area Leader, Inflammatory Bowel Disease, Immunology Therapeutic Area, Janssen. “We’re particularly excited to add an oral, peptide-based therapy to our robust portfolio as we aim to address the increasing incidence of inflammatory bowel disease and the growing needs of people living with Crohn’s disease and ulcerative colitis around the world.”

The transaction is expected to close in the third quarter of 2017.

PROTAGONIST PRESS RELEASE

Protagonist Therapeutics Enters into Worldwide Agreement with Janssen to Co-Develop and Commercialize PTG-200 for Inflammatory Bowel Disease

· Protagonist grants Janssen exclusive, worldwide rights to PTG-200, a first-in-class oral peptide IL-23 receptor antagonist currently in pre-clinical development

· Protagonist to receive a $50 million upfront payment and potentially up to an additional $940 million in development and sales milestones; double-digit tiered royalties on net sales

· Protagonist and Janssen to co-fund development through Phase 2; Protagonist retains option to co-detail U.S. prescribers

· Protagonist to host conference call and webcast today, May 30, at 8:00 a.m. Eastern Daylight Time

Newark, California (May 30, 2017): Protagonist Therapeutics, Inc. (Nasdaq: PTGX) today announced that the company has entered into a worldwide license and collaboration agreement with Janssen Biotech, Inc., one of the Janssen Pharmaceutical Companies of Johnson & Johnson, for the co-development and commercialization of PTG-200, Protagonist’s first-in-class, oral peptide IL-23 receptor antagonist for all indications including inflammatory bowel disease (IBD). PTG-200 is expected to enter Phase 1 clinical testing in normal healthy volunteers in the second half of 2017. The agreement builds upon a Johnson & Johnson Innovation — JJDC, Inc. Series B venture financing from 2013 in support of the discovery and development of Protagonist’s pipeline of oral peptide therapeutics.

“We are very pleased to partner with Janssen, a world-leader in the development of innovative therapies for patients suffering with chronic inflammatory and immunomodulatory diseases. As an oral IL-23 receptor antagonist, PTG-200 nicely complements Janssen’s current IBD portfolio,” said Dinesh V. Patel, Ph.D., Protagonist’s President and Chief Executive Officer. “The funding provided by this transaction enables us to advance our platform and clinical pipeline of innovative peptide drugs, including our lead oral peptide alpha-4-beta-7 integrin antagonist, PTG-100, which is currently in a Phase 2b clinical trial as a potential treatment for ulcerative colitis.”

“Our oral peptide PTG-200 works by blocking the IL-23 pathway, a mechanism which has been proven by injectable antibodies, including an approved drug and others in different stages of clinical development,” said David Y. Liu, Ph.D., Protagonist’s Chief Scientific Officer and Head of R&D. “As evidenced by PTG-200, we believe our technology platform is validated in its ability to generate potential first-in-class oral peptides as the next generation of targeted therapy drugs for IBD.”

Terms of the Collaboration

Under the terms of the license and collaboration agreement, Protagonist will receive an upfront payment of $50 million from Janssen, and will also be eligible to receive up to an additional $940 million in development, regulatory, and sales milestones. The development milestones represent significant payments that Protagonist would receive upon completion of each component of the Phase 2a/2b clinical trial in Crohn’s disease if Janssen elects to retain its license following each of those events. Janssen will receive exclusive, worldwide rights to develop and commercialize PTG-200, and Protagonist will receive double-digit tiered royalties on net product sales.

Protagonist Therapeutics and Janssen will jointly conduct the development of PTG-200 through Phase 2 clinical proof-of-concept in Crohn’s disease, after which time Janssen will be responsible for development and commercialization. Per the terms of the agreement, Protagonist will have the right to co-detail PTG-200 in the United States.

The transaction is expected to close in the third quarter of 2017, subject to customary closing conditions.

Additional details regarding the collaboration can be found in Protagonist’s Form 8-K filed today with the Securities and Exchange Commission.

Conference Call and Webcast Information

Protagonist Therapeutics will host a conference call to discuss this transaction at 8:00 a.m. EDT today, May 30, 2017. The live webcast can be accessed under “Calendar of Events” in the Investors section of the company’s website at www.protagonist-inc.com. The webcast will be available for replay for 30 days on the company website. Alternatively, investors may listen to the call by dialing toll-free ###-###-#### from locations in the United States or via toll call ###-###-#### from outside the United States.

About PTG-200

PTG-200 is a first-in-class oral Interleukin-23 receptor (IL-23R) antagonist being co-developed with Janssen initially for the treatment of Crohn’s disease. PTG-200 is currently in pre-clinical development studies, and is expected to enter Phase 1 clinical testing in the second half of 2017.

PTG-200 may have the potential to transform the existing IBD treatment paradigm because it is designed to offer significant advantages over injectable antibody drugs, including improved convenience, patient compliance, and the potential for improved safety and tolerability compared to currently approved injectable antibody drugs.

About Protagonist Therapeutics

Protagonist Therapeutics is a clinical-stage biopharmaceutical company with a proprietary technology platform which is utilized to discover and develop novel peptide-based drugs to address significant

unmet medical needs. Its primary focus is on developing potential first-in-class oral targeted therapy-based peptide drugs that work by blocking biological pathways that are currently targeted by marketed injectable antibody drugs. Protagonist’s initial lead peptide product candidates, PTG-100 and PTG-200, are based on this approach, and the company believes these candidates have the potential to transform the existing treatment paradigm for inflammatory bowel disease (IBD), chronic gastrointestinal diseases consisting primarily of ulcerative colitis and Crohn’s disease.

PTG-100, a potential first-in-class oral peptide alpha-4-beta-7 integrin antagonist, is currently in a global Phase 2b clinical trial for treatment of moderate-to-severe ulcerative colitis. PTG-200, a first-in-class oral Interleukin-23 receptor antagonist for potential treatment of IBD, initially Crohn’s disease, is currently in pre-clinical development and is expected to enter a Phase 1 clinical study in the second half of 2017.

In addition to PTG-100 and PTG-200, the company is developing an injectable hepcidin mimetic PTG-300 as a potential orphan drug for the treatment of rare diseases such as beta-thalassemia. PTG-300 is currently being studied in a Phase 1 clinical trial.

Protagonist is headquartered in Newark, California with its pre-clinical and clinical staff in California, and discovery operations both in California and in Brisbane, Queensland, Australia. For further information, please visit http://www.protagonist-inc.com.
