Records and Audit Rights. Day One shall keep complete, true and accurate books and records for the purpose of determining the amounts payable under this Agreement. Such books and records shall be kept by Day One [*]. Day One shall make such accounting records available, on reasonable notice sent by MabCare, for inspection [*], by an independent certified public accounting firm nominated by MabCare and reasonably acceptable to Day One, for the purpose of verifying the accuracy of any statement or report given by Day One and to verify the accuracy of the payments due hereunder for any Calendar Year. Such auditor shall advise the Parties simultaneously promptly upon its completion of its audit whether or not the payments due hereunder have been accurately recorded, calculated, and reported, and, if not, the amount of such discrepancy. Except in the case of willful misconduct or fraud, [*]. The auditor shall be required to keep confidential all information learned during any such inspection, and to disclose to MabCare only such details as may be necessary to report the accuracy of Day One’s statement or report. MabCare shall be responsible for the auditor’s costs, unless the auditor certifies an underpayment by Day One that resulted from a discrepancy in a report that Day One provided to MabCare during the applicable audit period, which underpayment was more than [*] of the amount set forth in such report, in which case Day One shall bear the full cost of such audit. If such accounting firm identifies a discrepancy made during such period, any unpaid amounts or overpaid amounts that are discovered shall be paid/refunded promptly but in any event within [*] of the date of delivery of such accounting firm’s written report so correctly concluding, or as otherwise agreed upon by the Parties.

6.11
Taxes.
6.11.1
Withholding Taxes Generally. Except as set forth in this Section 6.11, each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the activities of the Parties under this Agreement. To the extent Day One is required by Applicable Law to withhold any taxes, duties, levies, imposts, assessments, deductions, fees, and other similar charges by Applicable Law or any Governmental Authority (“Withholding Taxes”) on any payment to MabCare, then Day One will pay such Withholding Taxes to the applicable Governmental Authority, will make the payment to MabCare of the net amount due after deduction or withholding of such taxes and will secure and, upon timely making such Withholding Taxes, promptly send to MabCare written evidence of such payment, as well as other information reasonably necessary for MabCare to substantiate the amount of taxes withheld. If Day One intends to withhold any taxes from any payment under this Agreement, Day One shall inform MabCare reasonably in advance of making such payment to permit MabCare an opportunity to provide any forms or information or obtain any taxing authority exemption or reduction as may be available to reduce or eliminate such withholding. In determining the amount to be withheld, Day One shall apply the reduced rate of withholding, or not withhold, as the case may be reflected in a properly executed IRS Form W-8BEN-E (or other appropriate form) received by Day One prior to the time that Day One makes any payment under this Agreement. In addition, Day One agrees to reasonably cooperate with MabCare in claiming refunds or exemptions from such deductions or withholdings under any relevant agreement or treaty which is in effect to ensure that any amounts required to be withheld pursuant to this Section 6.11.1 are reduced in amount to the fullest extent permitted by Applicable Law. MabCare shall not be responsible for any penalties or interests resulting from the failure by Day One to collect or remit any such Withholding Taxes. For clarity, any amounts withheld or deducted for taxes in accordance with this Section 6.11.1 shall be considered as having been paid to MabCare for purposes of this Agreement.
6.11.2
Withholding Action. Notwithstanding the foregoing, if, as a result of a Withholding Action by Day One, withholding is required by Applicable Laws with respect to any payment made by Day One to MabCare pursuant to this Agreement and the amount of such withholding exceeds the amount of withholding that would have been required with respect to such payment under Section 6.11.1 if Day One had not committed the Withholding Action, then Day One shall pay an additional amount to MabCare such that, after withholding from such payment contemplated by this Agreement and such additional amount, MabCare receives the same amount with respect to such payment as it would have received from Day One absent such Withholding Action by Day One; provided, however, that if MabCare also has undertaken a Withholding Action that has caused the withholding required by Day One to increase, Day One shall only be required to pay to MabCare the increased amount to the extent attributable to its own Withholding Action (and not to MabCare’s Withholding Action). For purposes of this Section 6.11.2, “Withholding Action” means, in the case of Day One or MabCare, as the case may be, (a) a permitted assignment or sublicense of this Agreement (in whole or in part) by Day One or MabCare, as the case may be, to an Affiliate or a Third Party outside of Day One’s or MabCare’s, as the case may be, then-current jurisdiction; or (b) a redomiciliation of Day One or MabCare, as the case may be to, or

payment made by or on behalf of Day One from or received by or on behalf of MabCare, in a jurisdiction outside Day One’s or MabCare’s, as the case may be, then-current jurisdiction of residence.
6.11.3
VAT. All payments under this Agreement are exclusive of any value added, sales and use, excise, stamp, or similar country-specific, governmental or local taxes (collectively, “VAT”). If any VAT is required in respect of any payments under Applicable Law paid to the Party making the supply or providing the service, the Party making such payment shall pay VAT at the applicable rate in respect of any such payments upon the receipt of a valid VAT invoice in the appropriate form issued in respect of those payments, such VAT to be payable on the due date of the payments to which such VAT relates. For clarity, the paying Party shall not deduct any payment of VAT against the payments due to the other Party hereunder. The Parties will reasonably cooperate to issue valid VAT invoices for all amounts due under this Agreement consistent with VAT requirements. A Party shall not be responsible for any penalties and interest resulting from the failure by the other Party to collect (if not included on a valid VAT invoice) or remit any such VAT. The Parties shall reasonably cooperate to report and claim refunds or exemptions from any such VAT imposed on the transactions contemplated in this Agreement to the fullest extent permitted by Applicable Law and to timely file all required VAT tax returns.
6.12
Blocked Currency. If due to Applicable Law in a country or other jurisdiction in the Territory, it becomes impossible or illegal for Day One to transfer, or have transferred on its behalf, payments owed to MabCare under this Agreement with respect to such country, then Day One shall promptly notify MabCare and, thereafter, amounts accrued in such country under this Article 6 shall be paid to MabCare (or its designee) in such country in local currency by deposit in a local bank designated by MabCare and to the credit of MabCare, unless the Parties otherwise agree.

Day One Expands Pipeline with Potential First-in-Class Clinical-Stage Antibody Drug Conjugate (ADC) Targeting PTK7 in Solid Tumors for Adult and Pediatric Cancers

Day One receives exclusive license for development and commercialization of MTX-13 (DAY301), which received IND clearance by the FDA in April 2024

 

Targets PTK7, highly expressed in broad range of adult and pediatric solid tumors

 

 

BRISBANE, Calif., June X, 2024 – Day One Biopharmaceuticals (Nasdaq: DAWN) (“Day One” or the “Company”), a commercial-stage biopharmaceutical company dedicated to developing and commercializing targeted therapies for people of all ages with life-threatening diseases, today announced it has entered into an exclusive licensing agreement (the Agreement) with MabCare Therapeutics (MabCare) for MTX-13, a novel ADC targeting protein-tyrosine kinase 7 (PTK7). Pursuant to the terms of the Agreement, Day One has exclusive rights to develop, manufacture, and commercialize MTX-13 worldwide, excluding Greater China.

 

In April 2024, the U.S. Food and Drug Administration (FDA) cleared the investigational new drug (IND) application for MTX-13, which going forward will be identified as DAY301. In pre-clinical studies, DAY301 showed antitumor activity in a wide range of solid tumors.

 

“Our priorities for 2024 are to successfully launch OJEMDATM (tovorafenib), to advance our existing programs and to expand our pipeline by in-licensing clinical-stage assets that have the potential to transform outcomes for patients of all ages living with cancers,” said Jeremy Bender, Ph.D., chief executive officer of Day One. “We are excited by the opportunity presented by DAY301, and we believe we have the right team in place to develop the program to its full potential.”

 

DAY301 targets PTK7, a highly-conserved, catalytically inactive transmembrane protein that is overexpressed in multiple adult cancers, including esophageal, ovarian, lung, and endometrial cancer, as well as pediatric cancers such as neuroblastoma, rhabdosarcoma and osteosarcoma. PTK7 has limited expression in normal tissues or organs, making it an attractive target for therapeutic development.

 

“The addition of DAY301 to our pipeline strategically fits our mission of advancing both pediatric and adult medicines in areas of unmet need with equal urgency,” said Dr. Samuel Blackman, co-founder and head of research and development at Day One. “We believe the linker-payload technology embodied in DAY301 will overcome the limitations of earlier PTK7-targeted ADCs, giving us a potential first-in-class

 


 

drug against a clinically-validated target. We are excited to add this program to Day One and will look to enter the clinic in the coming months.”

 

Under the terms of the licensing agreement, MabCare will receive $55 million upfront, and is eligible to receive an additional $1.152 billion in development, regulatory and commercial success-based milestones, plus low-to-mid single-digit royalties on net sales outside of Greater China. Day One expects the first patient to be dosed in the Phase I study in late Q4 2024 or early Q1 2025.

 

About Day One Biopharmaceuticals

Day One Biopharmaceuticals is a commercial-stage biopharmaceutical company that believes when it comes to pediatric cancer, we can do better. The Company was founded to address a critical unmet need: the dire lack of therapeutic development in pediatric cancer. Inspired by “The Day One Talk” that physicians have with patients and their families about an initial cancer diagnosis and treatment plan, Day One aims to re-envision cancer drug development and redefine what’s possible for all people living with cancer—regardless of age—starting from Day One.

 

Day One partners with leading clinical oncologists, families, and scientists to identify, acquire, and develop important targeted cancer treatments. The Company’s pipeline includes tovorafenib (OJEMDA™) and pimasertib.
