CASE ALLEGATIONS: Humanigen’s lead product candidate is its proprietary antibody lenzilumab, which is under development as a treatment for, among other things, cytokine storm associated with COVID-19.  Among other trials, Humanigen is investigating lenzilumab for the treatment of hospitalized COVID-19 patients in the ACTIV-5/BET-B study, which is part of a directed public-private partnership with the National Institutes of Health (“NIH”).  In May 2021, Humanigen submitted an application to the U.S. Food and Drug Administration (“FDA”) requesting Emergency Use Authorization (“EUA”) for lenzilumab for the treatment of patients hospitalized with COVID-19.

The Humanigen class action lawsuit alleges that defendants failed to disclose that: (i) lenzilumab was less effective in treating hospitalized COVID-19 patients than defendants had represented; (ii) as a result, the FDA was unlikely to approve the lenzilumab EUA and the ACTIV-5/BET-B study was unlikely to meet its primary endpoint; and (iii) accordingly, lenzilumab’s clinical and commercial prospects were overstated.

On September 9, 2021, Humanigen announced that the FDA had rejected the lenzilumab EUA, advising investors that, “[i]n its letter, [the] FDA stated that it was unable to conclude that the known and potential benefits of lenzilumab outweigh the known and potential risks of its use as a treatment for COVID-19.”  On this news, Humanigen’s stock price fell more than 47%.

Then, on July 13, 2022, Humanigen disclosed that lenzilumab had failed to show statistical significance on the primary endpoint of the ACTIV-5/BETB study.  On this news, Humanigen’s stock price fell by nearly 80%, further damaging investors.

THE LEAD PLAINTIFF PROCESS: The Private Securities Litigation Reform Act of 1995 permits any investor who purchased or acquired Humanigen securities during the Class Period to seek appointment as lead plaintiff.  A lead plaintiff is generally the movant with the greatest financial interest in the relief sought by the putative class who is also typical and adequate of the putative class.  A lead plaintiff acts on behalf of all other class members in directing the Humanigen class action lawsuit.  The lead plaintiff can select a law firm of its choice to litigate the Humanigen class action lawsuit.  An investor’s ability to share in any potential future recovery is not dependent upon serving as lead plaintiff of the Humanigen class action lawsuit.
