ATLANTA, GA – – (Newsfile Corp. – September 22, 2022) – – Holzer & Holzer, LLC informs investors that a class action lawsuit was filed against Humanigen, Inc. (“Humanigen” or the “Company”) (NASDAQ: HGEN).  The lawsuit alleges Humanigen made materially false and misleading statements and/or failed to disclose that: (1) its product, lenzilumab, was less effective in treating hospitalized COVID-19 patients than the Company had represented; (2) as a result, the FDA was unlikely to approve an emergency use authorization for lenzilumab and the ACTIV-5/BET-B study was unlikely to meet its primary endpoint; (3) accordingly, lenzilumab’s clinical and commercial prospects were overstated.


If you bought shares of Humanigen between May 28, 2021 to July 12, 2022, and you suffered a significant loss on that investment, you are encouraged to discuss your legal rights by contacting Corey Holzer, Esq. at or Joshua Karr, Esq. at, by toll-free telephone at (888) 508-6832 or you may visit the firm’s website at to learn more.
