Previous wording

Our publicly disclosed immunology programs target STAT6, IRF5 and IRAK4, each of which addresses targets within validated pathways, providing the opportunity to treat a broad range of diseases. We are developing KT-621 as part of our STAT6 program, which is currently being evaluated in patients with Atopic Dermatitis (AD) as part of our BroADen Phase 1b clinical trial. In May 2025, we announced KT-579, our lead molecule in our IRF5 program, which is currently in IND-enabling studies. We are collaborating with Sanofi S.A. (“Sanofi”) on the development of drug candidates targeting IRAK4. In June Sanofi communicated its decision to exercise its full participation election under the terms of the companies’ collaboration agreement, and to advance our next-generation IRAK4 degrader, KT-485/SAR447971, into clinical testing. As a result, Sanofi intends to stop development of KT-474. In June 2025, we announced a strategic collaboration with Gilead Sciences, Inc. (“Gilead”) to develop novel oral molecular glue degraders for cyclin-dependent kinase 2 (CDK2). In May 2025 we announced our strategic decision not to advance our TYK2 degrader, KT-295, into clinical development, even though we completed IND-enabling activities with no adverse findings in any of our studies, to dedicate more human and capital resources to our other immunology programs, as well as to extend our cash runway. Our additional pipeline programs focus on addressing high impact targets that have been elusive to conventional modalities and that drive the pathogenesis of multiple serious diseases with significant unmet medical needs.
