WATERTOWN, Mass., July 08, 2024 (GLOBE NEWSWIRE) — Kymera Therapeutics, Inc. (NASDAQ: KYMR), a clinical-stage biopharmaceutical company advancing a new class of small molecule medicines using targeted protein degradation (TPD), today announced that following a review of preliminary KT-474 safety and efficacy data by an Independent Data Review Committee, Sanofi has informed Kymera that it intends to expand the ongoing Hidradenitis Suppurativa (HS) and Atopic Dermatitis (AD) Phase 2 trials to more rapidly progress towards pivotal studies.

“We are pleased that Sanofi has taken steps to expand these studies, as we are firm believers in the potential for KT-474 to address significant unmet needs with large market potential,” said Nello Mainolfi, PhD, Founder, President and CEO, Kymera Therapeutics. “This expansion, supported by the results of the interim analysis, is intended to accelerate overall timelines and inform future registrational trials. We look forward to sharing further information as it is available, including trial designs and updated timing for the expanded Phase 2 data readouts.”

About KT-474 IRAK4 Degrader
KT-474 (SAR444656) is a first-in-class IRAK4 degrader in development for the treatment of immune-inflammatory diseases with significant patient need, such as hidradenitis suppurativa (HS), atopic dermatitis (AD), and potentially others. IRAK4 is a key protein of the myddosome complex that mediates signaling through IL-1 and toll-like receptors, which play a crucial role in initiating the immune response against invading pathogens. 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. KT-474 was the first heterobifunctional small molecule protein degrader to enter clinical development for immunological diseases. Sanofi, which is collaborating with Kymera on the development of KT-474 outside of the oncology and immuno-oncology fields, is conducting randomized, placebo-controlled Phase 2 clinical trials of KT-474 in both HS and AD.
