aid: belharra-therapeutics name: Belharra Therapeutics description: >- Belharra Therapeutics is a privately held, next-generation chemoproteomics company headquartered at 3985 Sorrento Valley Boulevard, Suite C, San Diego, California, that is building small molecule therapeutics against targets the industry has long considered undruggable. Its Searchlight platform is an unbiased chemoproteomics screening system designed to illuminate novel, previously invisible binding pockets on high-value proteins across the proteome — the company states it can identify small molecule binders for any binding site, on any protein, in any conformational state, in any cell type, and reported having identified more than four thousand drug-like pocket probes by January 2024. The company was incubated and supported by Versant Ventures out of foundational chemoproteomics research at The Scripps Research Institute, with co-founders including Christopher G. Parker and Benjamin Cravatt of Scripps Research and Stuart Schreiber of the Broad Institute of MIT and Harvard. Jeff Jonker was hired as chief executive officer in September 2021, and the company debuted publicly in January 2023 with $130 million in hand — a $50 million Series A led by Versant Ventures plus an $80 million upfront payment from a multi-year Genentech collaboration spanning oncology, immuno-oncology, autoimmune and neurodegenerative disease. In June 2024 it announced a strategic immunology collaboration with Sanofi carrying up to $40 million in upfront and near-term milestone payments, and in January 2025 it appointed Sean Buchanan as chief scientific officer. Belharra runs no developer program and publishes no product API, developer portal, API reference, or SDK.
