On June 25, 2025, Kymera Therapeutics, Inc. (the “Company”) issued a press release, a copy of which is furnished herewith as Exhibit 99.1.

The information in this Item 7.01, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such filing.

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. In addition, any forward-looking statements represent the Company’s views only as of the date on which it was made and should not be relied upon as representing its views as of any subsequent date. The Company explicitly disclaims any obligation to update any forward-looking statements. No representations or warranties (expressed or implied) are made about the accuracy of any such forward-looking statements.
