35Pharma is a Canada-based, private, clinical-stage biopharmaceutical company headquartered in Montreal, Quebec, with a research hub in Boston, Massachusetts. It designs and develops next-generation protein-based therapeutics — multi-specific Activin x GDF ligand traps engineered against the TGF-beta superfamily — for pulmonary hypertension, heart failure, cardiometabolic disease and obesity. Its lead program, HS235, is a precision-engineered activin signalling inhibitor that has completed Phase I healthy-volunteer studies and is entering proof-of-principle trials in PAH and PH-HFpEF; a second program, HS370, targets heart failure and obesity. 35Pharma publishes no developer program, API, or machine-readable API artifacts of any kind — it is a therapeutics developer, not a software or data provider. On 25 February 2026 the company announced an agreement to be acquired by GSK plc.
