Investigation into Gossamer Bio, Inc. by Pomerantz Law Firm

Pomerantz LLP, a well-regarded firm specializing in corporate, securities, and antitrust class litigation, is probing claims related to Gossamer Bio, Inc. (NASDAQ: GOSS). This investigation arises after the company's alarming announcement regarding its Phase 3 PROSERA trial assessing seralutinib for treating pulmonary arterial hypertension. The trial did not meet its primary endpoint, prompting immediate reactions from investors and a sharp decline in Gossamer's stock price.

On February 23, 2026, Gossamer reported that its clinical trial results were unfavorable, leading to a staggering drop of 80.14%, which saw the stock close at just $0.423 per share. This abrupt downturn has raised questions about whether Gossamer and its executives engaged in securities fraud or other illegal business practices leading up to this revelation.
