LOS ANGELES--(BUSINESS WIRE)--The Law Offices of Frank R. Cruz<\/a> reminds investors of the upcoming June 1, 2026 <\/b>deadline to participate as a lead plaintiff in the securities fraud class action lawsuit filed on behalf of investors who acquired Gossamer Bio, Inc. (\u201cGossamer\u201d or the \u201cCompany\u201d) (NASDAQ: GOSS<\/a>) securities between June 16, 2025 and February 20, 2026<\/b>, inclusive (the \u201cClass Period\u201d).<\/p><\/a><\/a>

\nIF YOU ARE AN INVESTOR WHO LOST MONEY ON GOSSAMER BIO, INC. (GOSS), CLICK <\/b>HERE<\/b><\/a> TO PARTICIPATE IN THE SECURITIES FRAUD LAWSUIT.<\/b><\/p>

\nWhat Happened?<\/b><\/p>

\nOn 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.<\/p>

\nOn this news, Gossamer\u2019s stock price fell $1.71, or 80.3%, to close at $0.42 per share on February 23, 2026, thereby injuring investors.<\/p>

\nWhat Is The Lawsuit About?<\/b><\/p>

\nThe complaint filed in this class action alleges that throughout the Class Period, Defendants made materially false and\/or misleading statements, as well as failed to disclose material adverse facts about the Company\u2019s business, operations, and prospects. Specifically, Defendants failed to disclose to investors that: (1) patients at the Latin American sites were largely heavily-treated and lower risk and, ultimately, performed particularly well on the placebo, thus, Gossamer\u2019s Phase 3 PROSERA study failed to meet the primary endpoint of improved six-minute walk distance at week 24; and (2) as a result, Defendants\u2019 positive statements about the Company\u2019s business, operations, and prospects were materially misleading and\/or lacked a reasonable basis at all relevant times.<\/p>

\nIf you purchased or otherwise acquired Gossamer securities between June 16, 2025 and February 20, 2026, the deadline to seek appointment as the lead plaintiff in the securities fraud class action is June 1, 2026.<\/b><\/p>
