Lawsuit Deadline Nears for Gossamer Bio Investors Alleging Concealed Placebo Risk in Failed Drug Trial
Summary
A law firm issued a deadline alert for investors to join a class-action lawsuit against Gossamer Bio, with a lead plaintiff deadline of June 1, 2026.

This follows the company's prior disclosures in its 10-K and 10-Q filings regarding the class action. The detailed allegations of misconduct add to the severe financial distress, Nasdaq delisting notice, and ongoing distressed debt exchange already facing Gossamer Bio.
