Gossamer Bio Faces Investor Lawsuit After Phase 3 PROSERA Trial Miss

Levi & Korsinsky said it is investigating potential securities-law claims involving Gossamer Bio after the company’s Phase 3 PROSERA trial of seralutinib missed its primary endpoint, triggering a drop of more than 60% in the stock. The firm alleges the company’s prior trial guidance and optimistic commentary did not disclose that the study’s statistical plan required a more stringent significance threshold of alpha 0.025, and that the reported p-value of 0.032 would have met a conventional 0.05 standard but failed the pre-specified requirement.
