NEW YORK, May 08, 2026 (GLOBE NEWSWIRE) --
Bragar Eagel & Squire, P.C., a nationally recognized stockholder rights law firm, announces that a class action lawsuit has been filed against Immutep Ltd. (“Immutep” or the “Company”) (NASDAQ:IMMP) in the United States District Court for the Southern District of New York on behalf of all persons and entities who purchased or otherwise acquired Immutep American Depositary Receipts (“ADRs”) between March 24, 2025 and March 12, 2026, both dates inclusive (the “Class Period”). Investors have until July 6, 2026 to apply to the Court to be appointed as lead plaintiff in the lawsuit.
According to the lawsuit, throughout the Class Period, defendants made false and/or misleading statements and/or concealed the status and prospects of the TACTI004 trial based on continuing positive efficacy and safety readouts of eftilagimod alfa's ("efti") performance in other trials, particularly following positive top-line results from Immutep's prior TACTI-002 and INSIGHT-003 studies. Further, defendants announced in a Form-K filed with the Securities and Exchange Commission in January 30, 2026, that the trial was exhibiting "strong operational progress" and the planned interim futility analysis remained "on track for the first quarter of 2026." In truth, Immutep were aware of or were reckless, based on their access to internal clinical data, analyses, and reports concerning the TACTI-004 trial and its planned interim futility evaluation, that then-existing information materially increased the risk that the study would fail to meet its primary efficacy and/or safety endpoints. When the true details entered the market, the lawsuit claims that investors suffered damages.
