For each Hit Program conducted by Kronos, if, at any point from delivery of the ESR Data Package of the applicable Discovery Hit until the later of expiration of the applicable ESR Term or LSR Term, Genentech [***] related to the foregoing, then, within [***] of such determination, Genentech may elect to either [***]. If Genentech [***].

3.3.4    Kronos [***]. Unless the Parties agree otherwise, Kronos shall be obligated to conduct no more than [***], provided that Genentech shall [***] (each such selection by Genentech, a “Kronos Program Election”). The activities under each such Kronos Program Election shall consist of either [***]. Notwithstanding the foregoing, if the Parties mutually agree to conduct activities under an additional Discovery Research Program for an additional transcription factor pursuant to Section 3.2.9 (Option for Additional Designated TF), then Kronos shall be obligated to conduct no more than [***] total across all Designated TFs. In general, [***] and provided that:

3.3.4.1    if Genentech does not nominate any Discovery Hits as Modulator Compounds from [***] Discovery Research Program for a Designated TF, Genentech may

[***];

3.3.4.2    if Genentech nominates [***] as a Modulator Compound from the first-to-complete Discovery Research Program for Designated TF, Genentech shall [***]; and

3.3.4.3    if Genentech provides notice that it desires to nominate [***] Discovery Hits as Modulator Compounds from the [***] Discovery Research Program for a Designated TF (the “Earlier Designated TF”) (a) Genentech shall actually nominate [***], and (b) if Genentech did not actually nominate under clause (a) [***] (the “Later Designated TF”). If Genentech does not nominate any Discovery Hits as Modulator Compounds from such subsequent Discovery Research Program for the Later Designated TF, then Genentech [***] for such Earlier Designated TF. In the event that the Parties agree to an additional Discovery Research Program pursuant to Section 3.2.9 (Option for Additional Designated TF), [***]. For clarity, in the event Genentech nominates [***] Discovery Hits from a Discovery Research Program at different points in time as set forth in this Section 3.3.4, the total Discovery Hit nomination fees shall nevertheless be as set forth in Section 6.3.1 (Discovery Hit Nomination Fee).  For example, if [***], then in the event a [***]. Nothing in this Section 3.3.4.3 shall prevent Genentech from nominating [***] Discovery Hits for the Earlier Designated TF during the [***] Qualified Hit Evaluation Period, electing its Kronos Program Election for one (1) such Discovery Hit, and, in the event Kronos does not exercise its right to conduct the Hit Program for such Discovery Hit(s) as set forth below, initiating Program Transition of the other nominated Discovery Hits.

In the event a [***]. The foregoing provisions in this Section 3.3.4 are collectively the “Kronos [***].”

Kronos shall have the right, in its discretion but [***] to conduct Hit Programs for Discovery Hits as Modulator Compounds that are in excess of the Kronos [***]. If Kronos declines to perform ESR Activities for a Discovery Hit because [***], Kronos shall notify Genentech within [***] days and then Genentech may, within [***] of Kronos’s notice of its decision to so decline to Genentech, elect to conduct lead identification and optimization activities itself (or through a Third Party). For the avoidance of doubt, in the event that the Kronos [***] is exceeded, and Genentech conducts [***].

For any Hit Program for which Genentech elects to conduct lead identification or optimization activities that are [***], (i) a Program Transition pursuant to Section 4.1 (Program Transition) for such Hit Program shall initiate, (ii) [***].

3.3.5    Failure to Meet Lead Series Criteria or Development Candidate Criteria. For each Hit Program conducted by Kronos for which Kronos is unable to deliver (a) a series of Compounds [***], in each case (a) or (b), Genentech may elect to (A) terminate such Hit Program or (B) initiate a Program Transition of such Hit Program.

For any Hit Program for which Genentech elects to initiate a Program Transition under this Section 3.3.5, (A) a Program Transition pursuant to Section 4.1 (Program Transition) for such Hit Program shall initiate, (B) until Genentech identifies a Development Candidate or terminates such Hit Program, Genentech shall [***]. For clarity, under no circumstances shall Genentech be obligated to include structural information from such Hit Program in any such summary update.

3.4    Heterobifunctional Compound Hit Programs. For each Hit Program where a Discovery Hit or a Nominated Lead Series is advanced as a Heterobifunctional Compound pursuant to Section 3.2.8 (Discovery Hit Nomination), (a) a Program Transition pursuant to Section 4.1 (Program Transition) for such Hit Program shall initiate, (b) Genentech shall undertake the applicable hit-to-lead activities or optimization activities for such Discovery Hit or Nominated Lead Series, (c) until Genentech identifies a Development Candidate or terminates such Hit Program, Genentech shall [***].

3.5    Kronos Deliverables. Without limiting the obligations set forth in Section 8.1.1 (Disclosure), Kronos shall provide [***] in the Discovery Research Plan or agreed to by the JPT.

3.6    Materials. Genentech shall provide Kronos with the data and tangible materials specified under the applicable Discovery Research Plan and any additional materials as agreed by the JPT, which may include knockout cells, constructs, RNA-seq data, proteomics data, and any unmodified progeny or copies of such materials (collectively, the “Materials”).

In the event that the IP assignments, ownership, or license grants to a Party contain conflicting assignments or grants to such Party with respect to any specific time period, the Parties agree that any terms specifying ownership of IP by, or assignment of IP, to such Party shall take precedence over any terms specifying a license grant to such Party for such time period, and any terms specifying exclusive license rights shall take precedence over any terms specifying non-exclusive license rights for such time period.

5.2    Exclusivity.

5.2.1    Initiation of Discovery Research Program Until Commencement of Hit Program. For each Designated TRN of a Designated TF, from the Effective Date (or the date a Designated TF is designated if occurring after the Effective Date) until (a) commencement of a Hit Program for such Designated TRN, or (b) if no Discovery Hits for such Designated TRN are nominated by Genentech, the expiration of the Qualified Hit Evaluation Period, Kronos shall not itself, or with or for any Affiliate or Third Party, [***] (collectively “Designated TRN Components”), including [***]. If a Designated TF is [***], as of the effective date of [***], the foregoing restriction shall not apply to the [***], but shall apply to the Designated TRN of the Designated TF that is [***].

5.2.2    Hit Program – General. For each Designated TRN for which Genentech has elected to nominate one or more Discovery Hit(s), Kronos shall not itself, or with or for any Affiliate or Third Party, [***].

5.2.3    MOA-C Cool Off Period. Notwithstanding Section 5.2.2 (Hit Program – General), if [***], nothing in Section 5.2.2 (Hit Program – General) shall prevent Kronos (itself or with or through a Third Party or Affiliate) from [***]. For clarity, the foregoing sentence of this Section 5.2.3 shall not apply with respect to any Qualified Hit from any other Designated TRN to which the exclusivity obligations set forth in Section 5.2.2 (Hit Program – General) apply.

5.2.4    Hit Program – Target. Without limiting Section 5.2.2 (Hit Program – General), with respect to any Target to which a Discovery Hit of a Hit Program is directed [***], Kronos shall not itself, or with or for any Affiliate or Third Party, [***] until the earlier of [***] for Discovery Hits directed to such Target.

5.2.5    Change of Control of Kronos. During the Term, if Kronos undergoes a Change of Control, and on the date of the closing of such Change of Control or at any time thereafter, the Acquirer is engaged in the discovery, research, development, manufacture, or commercialization activities for any molecule that would be subject to the restrictions described in Section 5.2.1 through Section 5.2.4 above if conducted by Kronos (each, a “Competing Program”), then [***].

5.2.6    Existing Programs. Genentech understands and acknowledges that as of the Effective Date, Kronos has conducted internal research and discovery efforts with respect to transcription factors that are other than the initial Designated TFs, and in the mapping of such transcription factors has identified molecules (some of which are other transcription factors) as Critical Node Components of the TRNs for such other transcription factors, all as and to the extent set forth in Exhibit 5.2.6 (each such molecule, an “Unrestricted Critical Node Component”). Accordingly, notwithstanding the foregoing provisions of Section 5.2 (Exclusivity), Kronos, itself or with or through an Affiliate or Third Party, shall have the right to conduct (a) research and discovery activities with respect to any such Unrestricted Critical Node, even if it is also identified as a Critical Node Component or Downstream Target of a Designated TRN, including (i) the mapping of the TRN for any Unrestricted Critical Node that is a transcription factor and (ii) the screening of any such Unrestricted Critical Node, and (b) activities otherwise designed to identify or optimize, develop or commercialize molecules that bind or modulate such Unrestricted Critical Node, provided that such molecule is not also intended to modulate any Designated TF (including by disrupting or facilitating a protein-protein interaction between the Designated TF and such Unrestricted Critical Node), or its associated Designated TRN Components, during the period in which any exclusivity with respect to such Designated TRN Component exists pursuant to Section 5.2.1 or 5.2.2. For clarity, should an Unrestricted Critical Node be identified as the Target of a Discovery Hit, the Target exclusivity set forth in Section 5.2.4 (Hit Program – Target) would not apply to such Unrestricted Critical Node.

5.3    Summary. Genentech understands that, as of the Effective Date, Kronos’s research and discovery organization is centered around the mapping of TRNs for transcription factors arising in different tumor types, and the research and discovery of molecules that modulate, directly or indirectly, the oncogenic activity of such transcription factors. The Parties also acknowledge that the nature of cancer biology is such that certain molecules (including Co-Factors and Upstream Regulators) may be expressed broadly across multiple tumor types. It is therefore possible that a protein or gene that is identified as a Critical Node Component in the context of the mapping of a given transcription factor in a given tumor type may well be identified as a Critical

Node Component in the context of the mapping of a different transcription factor in a the same or a different tumor type. Accordingly, Kronos, itself or with or through an Affiliate or Third Party, shall have the right to conduct (a) research and discovery activities with respect to any transcription factor that is not a Designated TF, including (i) the mapping of the TRN for such transcription factor (a “Reserved TRN”), and (ii) the screening of any Critical Node Components of such Reserved TRN, and (b) activities otherwise designed to identify or optimize, develop or commercialize molecules that bind or modulate any such Critical Node Components of such Reserved TRN, provided that Kronos’s right to conduct the activities described in subclauses (a) and (b) above shall not include doing so (A) in connection with any Target of a Hit Program or Critical Node Component of a Designated TRN (including any Critical Node Component that is common between such Designated TRN and a Reserved TRN); or (B) with the intent to modulate such Designated TRN, in each case of (A) and (B), during any period that is subject to exclusivity under Section 5.2 (Exclusivity).

5.4    Right to Perform Obligations Under Agreement. Notwithstanding anything to the contrary in Section 5.2 (Exclusivity), Kronos shall have the right to perform its obligations under any Discovery Research Plan during the applicable Discovery Research Term, ESR Plan during the applicable ESR Term, or LSR Plan during the applicable LSR Term.

6.1    Upfront Fee. In consideration for the rights and licenses set forth herein, no later than [***] following the Effective Date, Genentech shall pay Kronos a one-time, non-creditable, non-refundable upfront payment in the amount of twenty million US Dollars ($20,000,000).

6.2    Expansion Fees.

6.2.1    [***]. For each Discovery Research Program for which Genentech elects to exercise its option to have Kronos conduct [***], Genentech shall pay Kronos, in accordance with Section 7.1.1 (Expansion Fees, Nomination Fees), a [***].

6.2.2    [***]. For each Discovery Research Program for which Genentech elects to exercise its option to have Kronos conduct [***], Genentech shall pay Kronos, in accordance with Section 7.1.1 (Expansion Fees, Nomination Fees), [***].

6.2.3    [***]. For each Discovery Research Program for which Genentech elects to exercise its option to have Kronos conduct [***], Genentech shall pay Kronos, in accordance with Section 7.1.1 (Expansion Fees, Nomination Fees), [***].

6.2.4    [***]. For each Discovery Research Program for which Genentech elects to exercise its option to have Kronos conduct [***], Genentech shall pay Kronos, in accordance with Section 7.1.1 (Expansion Fees, Nomination Fees), [***].

6.2.5    [***]. If Genentech elects to exercise its option to designate [***] as a Designated TF and commence a new Discovery Research Program for such Designated TF [***], Genentech shall pay Kronos, in accordance with Section 7.1.1 (Expansion Fees, Nomination Fees), [***].

6.3    Nomination Fees.

6.3.1    Discovery Hit Nomination Fee.

[***]

6.3.2    Lead Series Nomination Fee. For each Lead Series that Genentech nominates to be advanced as a Nominated Lead Series pursuant to Section 3.3.1.1 (ESR Activities), subject to Section 6.7.1.1 (Program Transition of Hit Program During ESR Term or Before ESR Activities), on a Nominated Lead Series-by-Nominated Lead Series basis, Genentech shall pay Kronos, in accordance with Section 7.1.1 (Expansion Fees; Nomination Fees; [***]), a one-time, non-creditable, non-refundable Lead Series nomination fee in the amount of [***] (“Lead Series Nomination Fee”).

6.3.3    Development Candidate Nomination Fee. For each Hit Program where Genentech nominates a potential Development Candidate to be advanced as a Development Candidate pursuant to Section 3.3.2.1 (LSR Activities), 3.3.2.2(a) (General), 3.3.2.2(b) ([***]), 3.3.3 (Capabilities Requirements), 3.3.4 (Kronos [***]), 3.3.5 (Failure to Meet Lead Series Criteria or Development Candidate Criteria) or 3.4 (Heterobifunctional Compound Hit Programs), subject to Section 6.7.1 (Payment Reduction for [***]), Genentech shall pay Kronos, in accordance with Section 7.1.1 (Expansion Fees; Nomination Fees; [***]), a one-time, non-creditable, non-refundable Development Candidate nomination fee in the amount of [***] (“Development Candidate Nomination Fee”). Genentech shall notify Kronos promptly following its nomination of the Development Candidate, which shall be the [***], in order for Kronos to issue an invoice for payment in accordance with Section 7.1.1 (Expansion Fees; Nomination Fees; [***]). For clarity, no more than one (1) Compound shall be designated a Development Candidate per Hit Program and therefore no more than one (1) Development Candidate Nomination Fee shall be paid per Hit Program.

6.4    [***] Fees.

6.4.1    [***] Fee. If Genentech elects to [***], and Kronos [***], then [***] (the “[***] Fee”).

For illustration purposes only, [***].

6.4.3    [***] Fee. If, for a given Hit Program, (a) Genentech elects to [***], (b) Kronos has [***], and (c) Kronos [***], then Genentech shall [***] as follows for such Hit Program: (i) [***] (each of (i) or (ii), an “[***] Fee”). For clarity, if Genentech [***].

For illustration purposes only, [***].

6.5    Milestones.

6.5.1    Development and Regulatory Milestones. On a Hit Program-by-Hit Program basis, following the first achievement of each milestone event by the first Development Candidate or Licensed Product, as applicable, from such Hit Program, Genentech shall pay Kronos, in accordance with Section 7.1.2 (Milestone Payments), the corresponding non-creditable, non-refundable milestone payment set forth in the following table:

Each milestone payment specified in this Section 6.5.1 is payable one-time only for all Licensed Products arising from a given Hit Program regardless of the number of times such milestone events are reached and by how many Licensed Products arising from such Hit Program. For the avoidance of doubt, Genentech’s cumulative obligation under this Section 6.5.1 shall in no event exceed one hundred fifty million US Dollars ($150,000,000) for a given Hit Program.

For illustration purposes only, [***] .

If a clinical development or regulatory milestone event under this Section 6.5.1 for a given Hit Program is skipped in the development of a particular Licensed Product for a particular Indication or country, then such skipped milestone shall be payable upon achievement of the next clinical development or regulatory milestone event for the development of such Licensed Product for such Indication or such country.

For illustration purposes only, [***].

In addition, if a clinical trial for an Indication [***] in such clinical trial, then, such clinical trial [***] as applicable, shall be deemed achieved (to the extent not previously achieved) on the earlier of [***].

6.5.2    Net Sales Milestones. On a Hit Program-by-Hit Program basis, following the first achievement of each milestone event by the first Licensed Product from such Hit Program, Genentech shall pay Kronos, in accordance with Section 7.1.2 (Milestone Payments), the corresponding non-creditable, non-refundable milestone payment set forth in the following table:

The milestone event thresholds in this Section 6.5.2 shall be calculated based on aggregating the Net Sales of a Licensed Product made in each country in the Territory [***]. With respect to each Licensed Product in each country in the Territory, [***].

Each milestone payment specified in this Section 6.5.2 is payable one-time only for all Licensed Products from the same Hit Program regardless of the number of times such milestone events are reached and by how many Licensed Products in such Hit Program. For clarity, if two (2) or more milestone events in this Section 6.5.2 are first achieved in the same Calendar Year, then all such milestone payments corresponding to such milestone events achieved will be paid for such Calendar Year. For the avoidance of doubt, Genentech’s cumulative obligation under this Section 6.5.2 shall in no event exceed one hundred million US Dollars ($100,000,000) for a given Hit Program.

6.6    Royalties.

6.6.1    Royalties for Licensed Products. During the applicable Royalty Term, Genentech shall pay Kronos, in accordance with Section 7.1.3 (Royalty Payments), on a Licensed Product-by-Licensed Product and country-by-country basis, and subject to Section 6.7 (Payment Reductions and Offsets), a royalty on worldwide annual Net Sales of such Licensed Product, as follows:

The worldwide annual Net Sales thresholds in this Section 6.6.1 shall be calculated based on aggregating the Net Sales made in each country in the Territory in which the Royalty Term [***].

Genentech may make credit or debit adjustments for royalty-related payments made for a particular reporting period in a following period to reflect additional information that Genentech’s accounting department becomes aware of after such reporting period.

6.6.2    Royalty Term. The royalty obligations set forth in Section 6.6.1 (Royalties for Licensed Products) will commence on a Licensed Product-by-Licensed Product

and country-by-country basis upon the First Commercial Sale of a Licensed Product in a country, and expire on a country-by-country basis upon the later of: [***] (the “Royalty Term”).

6.6.3    Rights Following Expiration of Royalty Term. Upon expiration of its payment obligation hereunder with respect to a Licensed Product in a country, the license in Section 5.1.2.5 (Exclusive Commercial License) shall be fully paid-up, perpetual, and irrevocable in respect of that Licensed Product in that country.

6.6.4    Single Royalty. No more than one stream of royalty payments shall be due under Section 6.6.1 (Royalties for Licensed Products) with respect to sales of any one particular Licensed Product. For the avoidance of doubt, multiple royalties shall not be payable because the sale of a particular Licensed Product is Covered by more than one (1) Valid Claim in the country in which such Licensed Product is sold.

6.7    Payment Reductions and Offsets.

6.7.1    Payment Reduction for [***].

6.7.1.1    [***]. For each Discovery Hit nominated by Genentech for which [***],

12.1    Indemnification. Subject to Section 12.2 (Procedure), each Party shall indemnify, defend and hold each of the other Party, its Affiliates and their respective directors, officers, and employees and the successors and assigns of any of the foregoing harmless from and against any and all liabilities, damages, settlements, penalties, fines, costs or expenses (including, without limitation, reasonable attorneys’ fees and other expenses of litigation) (collectively, “Loss” or “Losses”) arising, directly or indirectly out of or in connection with any Third Party claims, suits, actions, demands or judgments (“Third Party Claims”) relating to (a) the negligence or willful misconduct of such Party, its Affiliates and their respective directors, officers, employees and subcontractors in the course of activities performed by or on behalf of such Party under this Agreement, (b) the activities performed by or on behalf of such Party in connection with the exercise of its licenses and rights and performance of its obligations hereunder, including, in the case of Genentech and its Affiliates and its and their Sublicensees hereunder, the making, developing, using, selling, importing, exporting or other exploitation of the Licensed Compounds and Licensed Products, or (c) breach by such Party of the representations and warranties under SECTION 11 (Representations and Warranties), except, in each case, to the extent caused by the negligence or willful misconduct of the other Party.

12.2    Procedure. If a Party intends to claim indemnification under this Agreement (the “Indemnitee”), it shall promptly notify the other Party (the “Indemnitor”) in writing of such alleged Loss. The Indemnitor shall have the right to control the defense thereof with counsel of its choice as long as such counsel is reasonably acceptable to Indemnitee. Any Indemnitee shall have the right to retain its own counsel at its own expense for any reason, provided, however, that if the Indemnitee shall have reasonably concluded, based upon a written opinion from outside legal counsel, that there is a conflict of interest between the Indemnitor and the Indemnitee in the defense of such action, the Indemnitor shall pay the fees and expenses of one law firm serving as counsel for the Indemnitee. The Indemnitee, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any Third Party Claims covered by this Agreement. The obligations of this SECTION 12 (Indemnification) shall not apply to any settlement of any Third Party Claims if such settlement is effected without the consent of both Parties, which shall not be unreasonably withheld or delayed. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, to the

extent prejudicial to its ability to defend such action, shall relieve the Indemnitor of any obligation to the Indemnitee under this Section 12.2 (Procedure). It is understood that only Genentech and Kronos may claim indemnity under this Agreement (on its own behalf or on behalf of its Indemnitees), and other Indemnitees may not directly claim indemnity hereunder.

Each Party shall maintain general liability insurance coverage at its own cost; provided, however, Genentech has the right, in its sole discretion, to self-insure, in part or in whole, for any such coverage. The insurance policies for such coverage shall be an occurrence form, but if only a claims made form is available to a Party, such Party shall maintain such coverage for at least [***] after the later of (a) termination or expiration of this Agreement or (b) such Party has no further obligations under this Agreement. Insurance coverage shall be primary insurance with respect to each Party’s own participation under this Agreement and shall be maintained [***]. On written request, each Party shall provide to the other Party certificates of insurance evidencing the insurance coverage required under this Section 12.3. Each Party shall provide to the other Party at least [***] notice of any cancellation, nonrenewal or material change in any of the required insurance coverages.

12.3.2    Commercial General Liability. During the Term of this Agreement and for three (3) years thereafter, each Party shall maintain commercial general liability insurance (a) combined single limit for bodily injury and property damage liability, in the minimum amount per occurrence of [***], all commencing as of the Effective Date.

12.4    Limitation of Damages.

13.2    Termination by Either Party for Material Breach. Either Party may terminate this Agreement in its entirety, or with respect to a particular Discovery Research Program or Hit Program, by written notice to the other Party for any material breach of this Agreement by the other Party if, in the case of remediable breach, such material breach is not cured within ninety (90) days (forty-five (45) days for a payment breach with respect to any undisputed amounts) after the breaching Party receives written notice of such breach from the non-breaching Party; provided that if such breach [***] is not capable of being cured within such 90-day period, [***] to cure such breach, so long as (a) [***], and (b) [***]. Notwithstanding anything to the contrary herein, if the allegedly breaching Party in good faith either disputes (i) whether a breach is material or has occurred or (ii) the alleged failure to cure or remedy (or non-remediable nature of) such material breach, and provides written notice of that dispute to the other Party within the above time periods, then the matter will be addressed under the dispute resolution provisions in SECTION 14 (Dispute Resolution), and the notifying Party may not terminate this Agreement until it has been determined under SECTION 14 (Dispute Resolution) that the allegedly breaching Party is in material breach of this Agreement, and such breaching Party further fails to cure such breach within ninety (90) days (forty-five (45) days for a payment breach with respect to any undisputed amounts) (or such [***]) after the conclusion of that dispute resolution procedure. For the avoidance of doubt, where the material breach is with respect to a particular Discovery Research Program or Hit Program, any termination shall be limited to that Discovery Research Program or Hit Program and not to this Agreement in its entirety.

13.3    Termination by Either Party for Insolvency or Bankruptcy. Either Party may terminate this Agreement effective on written notice to the other Party upon the liquidation, dissolution, winding-up, insolvency, bankruptcy, or filing of any petition therefor, appointment of a receiver, custodian or trustee, or any other similar proceeding, by or of the other Party where such petition, appointment or similar proceeding is not dismissed or vacated within ninety (90) days.

13.4    Elective Termination. Genentech shall have the right to permissively terminate this Agreement in its entirety, or with respect to a particular Discovery Research Program or Hit

Program, in its sole discretion, at any time by providing written notice to Kronos; such termination to be effective [***] days after such notice.

13.5    Effects of Termination.

13.5.1    Accrued Rights and Obligations. Upon expiration or termination of this Agreement for any reason all rights and obligations of the Parties hereunder shall terminate as of the date of a termination except as expressly set forth herein; provided however that such expiration or termination shall not release either Party hereto from any liability which, as of the effective date of such expiration or termination, had already accrued to the other Party or which is attributable to a period prior to such termination, nor preclude either Party from pursuing any rights and remedies it may have hereunder or at law or in equity which accrued or are based upon any event occurring prior to the effective date of such expiration or termination.

San Mateo, Calif., and Cambridge, Mass., January X, 2023 – Kronos Bio, Inc. (Nasdaq: KRON), a company dedicated to transforming the lives of those affected by cancer, announced today that it has entered into a discovery collaboration in the field of oncology with Genentech, a member of the Roche Group, focused on discovering and developing small-molecule drugs that modulate transcription factor targets selected by Genentech.

The partnership will allow Genentech to leverage Kronos Bio’s expertise to identify protein-protein interactions, genetic dependencies and gene expression signatures to better understand and target the oncogenic activity of transcription factors in cancer types of interest. Under the collaboration, researchers at the two companies will collaborate using Kronos Bio’s proprietary drug discovery platform, including the small molecule microarray (SMM) for hit finding, to build upon research conducted to date by Genentech.

“This, our first collaboration, brings together expertise from both companies with the goal of answering fundamental scientific questions about the biology of cancer that we hope will one day lead to the advancement of new clinical candidates,” said Norbert Bischofberger, Ph.D., president and chief executive officer of Kronos Bio. “We are pleased to be able to leverage our unique platform to collaborate with Genentech to further Kronos Bio’s understanding of transcription-driven oncogenesis and ability to identify novel targets involved.”

Kronos Bio will lead discovery and research activities to a defined preclinical point when Genentech will have the exclusive right to pursue further preclinical and clinical development and commercialization. Under the terms of the agreement, Kronos Bio will receive an upfront payment of $20 million and be eligible for additional payments, which could total up to $554 million, based on reaching certain milestones, including discovery, preclinical, clinical and commercial milestones, as well as tiered royalties on any potential products that are commercialized as a result of the collaboration.

“We are excited about the possibilities that this collaboration with Kronos Bio brings to further our understanding of complex scientific networks with the goal of bringing highly effective medicines to patients,” said James Sabry, Global Head of Roche Pharma Partnering.

Kronos Bio is focused on targeting the activity of oncogenic transcription factors that have a well-defined and central role in driving particular types of cancer. The company leverages its expertise to map transcription regulatory networks, enabling the identification of protein-protein interactions, genetic dependencies and gene expression signatures of specific oncogenic transcription factors in cancers of

interest. Utilizing these transcription regulatory network maps, the company relies on a number of tools, including its proprietary Small Molecule Microarray (SMM) to screen for new drug starting points.

Kronos Bio is a biopharmaceutical company that is advancing two investigational compounds in clinical trials for patients with cancer. The company is developing the CDK9 inhibitor, KB-0742, as a treatment for MYC-amplified solid tumors, and lanraplenib, a next-generation SYK inhibitor, for patients with relapsed/refractory FLT3-mutated acute myeloid leukemia. The company’s scientific focus is on developing medicines that target the dysregulated transcription that is the hallmark of cancer and other serious diseases.

Kronos Bio is based in San Mateo, Calif., and has a research facility in Cambridge, Mass. For more information, visit www.kronosbio.com or follow the company on LinkedIn.
