What Happened?
On February 23, 2026, Gossamer disclosed that results for its Phase 3 PROSERA study of seralutinib for the treatment of pulmonary arterial hypertension had failed to meet the primary endpoint, citing patients at Latin American sites performing particularly well on placebo due to enrollment of a heavily-treated lower-risk population.
On this news, Gossamer’s stock price fell $1.71, or 80.3%, to close at $0.42 per share on February 23, 2026, thereby injuring investors.
