On June 25, 2025, the Company announced an update to its collaboration with Sanofi S.A. ("Sanofi") on the development of drug candidates targeting IRAK4 outside of the oncology and immuno-oncology fields.

Sanofi has informed the Company that KT-485/SAR447971, an oral, highly potent and selective development candidate targeting IRAK4 for immuno-inflammatory diseases that the Company has discovered and characterized through preclinical studies, has been selected to advance into clinical studies. Following extensive preclinical work supporting its robust development potential, KT-485 is being prioritized for development under the companies' existing IRAK4 collaboration, and is expected to advance into Phase 1 testing next year. Based on the planned development of KT-485, Sanofi will not advance KT-474.

In conjunction with its plans to advance KT-485, Sanofi also communicated its decision to exercise its participation election right for the IRAK4 target under the terms of the companies' existing collaboration agreement. Under the existing agreement, the Company achieved a $20 million milestone in the second quarter of 2025 related to preclinical activities associated with KT-485. The Company is eligible to receive up to $975 million of potential clinical, regulatory and commercial milestones related to KT-485, including an additional milestone upon the start of Phase 1 clinical testing.

*The disclosure under this Item 8.01 contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, as amended, including, without limitation, implied and express statements about our expectations regarding strategy, business plans and objectives on the development of KT-485, including the therapeutic potential, clinical benefits and safety thereof. The words "may," "might," "will," "could," "would," "should," "expect," "plan," "anticipate," "intend," "believe," "expect," "estimate," "seek," "predict," "future," "project," "potential," "continue," "target," "upcoming" and similar words or expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Any forward-looking statements in this Current Report on Form 8-K are based on management's current expectations and beliefs and are subject to a number of risks, uncertainties and important factors that may cause actual events or results to differ materially from any forward-looking statements contained in this press release, including, without limitation, risks associated with: the timing and anticipated results of our current and future preclinical studies and clinical trials, supply chain, strategy and future operations; the delay of any current and future preclinical studies or clinical trials or the development of Kymera Therapeutics' drug candidates; the risk that the results of current preclinical studies and clinical trials may not be predictive of future results in connection with current or future preclinical and clinical trials, including for KT-474 and KT-485; Kymera Therapeutics' ability to successfully demonstrate the safety and efficacy of its drug candidates; the timing and outcome of the Kymera Therapeutics' planned interactions with to regulatory authorities; obtaining, maintaining and protecting its intellectual property; and Kymera Therapeutics' relationships with its existing and future collaboration partners, the timing and outcome of planned interactions with and submissions to regulatory authorities, the availability of funding sufficient for our operating expenses and capital expenditure requirements and other factors. These risks and uncertainties are described in greater detail in the section entitled "Risk Factors" in the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, as well as discussions of potential risks, uncertainties, and other important factors in the Company's subsequent filings with the Securities and Exchange Commission.

**Kymera Therapeutics Announces Sanofi IRAK4 Collaboration Update** 

*Sanofi to advance Kymera's next-generation oral IRAK4 degrader development candidate, KT-485, into clinical testing and will not advance KT-474* 

*In preclinical testing, KT-485 demonstrated increased selectivity and potency with a favorable safety profile* 

*Kymera is eligible for up to $975 million in collaboration milestones, double digit royalties, and may opt-in to 50/50 development and profit share of KT-485 in the U.S.* 

**Watertown, Mass. (June 25, 2025) –** <u>Kymera Therapeutics, Inc.</u> (NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing a new class of oral small molecule degrader medicines for immunological diseases, today announced an update to its IRAK4 partnership with Sanofi.

Sanofi has informed Kymera that KT-485/SAR447971, an oral, highly potent and selective development candidate targeting IRAK4 for immuno-inflammatory diseases that Kymera has discovered and characterized through preclinical studies, has been selected to advance into clinical studies. Following extensive preclinical work supporting its robust development potential, KT-485 is being prioritized for development under the companies' existing IRAK4 collaboration, and is expected to advance into Phase 1 testing next year. Based on the planned development of KT-485, Sanofi will not advance KT-474.

In conjunction with its plans to advance KT-485, Sanofi also communicated its decision to exercise its participation election right for the IRAK4 target under the terms of the companies' collaboration agreement. Under the agreement, Kymera achieved a $20 million milestone in the second quarter of 2025 related to preclinical activities associated with KT-485. Kymera is eligible to receive up to $975 million of potential clinical, regulatory and commercial milestones related to KT-485, including an additional milestone upon the start of Phase 1 clinical testing.

"Sanofi's intention to advance KT-485 into clinical testing and to direct all collaboration resources to the next-generation IRAK4 degrader is a reflection of the molecule's compelling preclinical profile and of Sanofi's and Kymera's commitment to transform immunology treatment paradigms. Both companies have a strong belief in and commitment to targeting the IRAK4 pathway with degraders that are functionally differentiated from small molecule inhibitors, and to bringing forward the best oral medicines to patients living with immunological diseases," commented Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics. "In preclinical testing, KT-485 demonstrated an improved target product profile as compared to KT-474. With greater potency and selectivity and a generally improved overall profile KT-485 is best-positioned to capitalize on the significant potential of IRAK4 degradation."

**About KT-485** 

KT-485/SAR447971 is a first-in-class, selective, potent, oral IRAK4 degrader in development for the treatment of immuno-inflammatory diseases with significant patient need. IRAK4 is a master regulator of innate immunity and key protein of the myddosome complex that mediates signaling through IL-1 and toll-like receptors. IRAK4 is a scaffolding kinase that acts at the interface of the innate and adaptive immune responses with a variety of functions depending on its kinase activity and scaffolding function. Eliminating IRAK4 completely through degradation impacts both the kinase and scaffolding functions, therefore having the potential to achieve a broad, well-tolerated, anti-inflammatory effect providing a novel therapeutic approach for a variety of immune-inflammatory diseases. Clinical data generated to date demonstrates the potential of IRAK4 degradation to deliver the combined activity of upstream biologics in an oral drug for multiple diseases. Sanofi, which is collaborating with Kymera on the development of IRAK4 degraders outside of the oncology and immuno-oncology fields, is progressing the IRAK4 program through clinical development. Per the collaboration, Kymera achieved a $20 million milestone related to preclinical activities associated with KT-485. Kymera is eligible to receive an additional milestone upon the start of Phase 1 clinical testing, part of up to $975 million of potential clinical, regulatory and commercial milestones.
