Descriptiontext

Biotheryx is a clinical-stage biopharmaceutical company headquartered in San Diego, California, focused on the discovery and development of first-in-class protein degraders for oncology and inflammatory diseases. The company's core technology is the proprietary PRODEGY (Protein Degrader Technology) platform, which leverages deep expertise in modulating Cereblon, the most widely validated E3 ligase involved in protein degradation. The platform enables the design of three degrader modalities: molecular glues that induce Cereblon-neosubstrate interactions to access the approximately 85% of proteins currently considered undruggable, bifunctional degraders that link Cereblon binders to target ligands, and hybrid degraders capable of degrading both neosubstrates and traditional binding-pocket proteins within a single molecule.

The clinical pipeline comprises three Phase 1-stage assets: BTX-9341, a first-in-class dual bifunctional degrader of CDK4/6 being developed for HR+/HER2- breast cancer patients resistant to existing CDK4/6 inhibitors (approximately 70% of whom develop acquired resistance); BTX-1188, an oral molecular glue targeting GSPT1 and IKZF1/3 for acute myeloid leukemia and solid tumors; and BTX-A51, an oral multi-kinase inhibitor (CK1α, CDK7, CDK9) for relapsed/refractory AML and solid tumors dependent on MYC. Preclinical programs include BTX-10908, a SOS1 bifunctional degrader for KRAS-driven cancers, and PDE4 degraders for inflammatory skin diseases.

Biotheryx operates a hybrid business model combining independent clinical development with strategic pharmaceutical partnerships. The company generates revenue through research collaboration and license agreements, receiving upfront technology access fees, R&D funding, milestone payments tied to regulatory and commercial achievements, and tiered single-digit royalties on net sales. The flagship partnership with Incyte, initiated in April 2023 and expanded in June 2025, provides Biotheryx with milestone potential of up to $354 million per target. The company has raised approximately $133 million in equity financing across Series D ($35M, July 2020) and Series E ($92M, May 2021) rounds, with institutional backers including Farallon Capital Management, MSD Partners, and The Leukemia & Lymphoma Society.

The company is advancing to the Phase 1 Dose Expansion portion of the trial to further evaluate efficacy and safety in up to 78 participants across multiple sites in the United States.PR NewswireBiotheryx Announces First Patient Dosed in the Dose Expansion Phase of BTX-9341-101 for the Treatment of HR+/HER2- Breast CancerBiotheryx announced that the first patient has been dosed in the dose expansion phase of its BTX-9341 clinical trial evaluating a CDK4/6 degrader in combination with fulvestrant for HR+/HER2- breast cancer patients who have previously received CDK4/6 inhibitor therapy. The randomized study is expected to enroll approximately 80 patients across two treatment arms at multiple U.S. sites, based on the recommended dose from the earlier dose escalation phase. The primary endpoint is Overall Response Rate, with secondary endpoints including Clinical Benefit Rate and Progression Free Survival.PR NewswireBiotheryx Announces Completion of Enrollment in Phase 1a Clinical Trial of BTX-9341 for the Treatment HR+/HER2- Breast CancerBiotheryx, a biopharmaceutical company focused on protein degraders for cancer, announced completion of enrollment in its Phase 1a clinical trial of BTX-9341, a first-in-class CDK4/6 degrader for advanced HR+/HER2- breast cancer patients who have previously received CDK4/6 inhibitor therapy. The trial tested BTX-9341 as monotherapy and in combination with fulvestrant, with primary objectives assessing safety, tolerability, pharmacokinetics, and pharmacodynamics. Topline data from the trial is expected in Q1 2026, representing a significant step toward advancing a novel treatment approach designed to overcome resistance mechanisms that limit current CDK4/6 inhibitors.SdbnBiotheryx Announces Completion of Enrollment in Phase 1a Clinical Trial of BTX-9341 for the Treatment HR+/HER2- Breast Cancer – San Diego Biotechnology NetworkBiotheryx, Inc. announced the completion of enrollment in its Phase 1a clinical trial for BTX-9341, an investigational treatment for HR+/HER2- breast cancer.
