The class action is on behalf of shareholders who purchased or otherwise acquired Immutep American Depositary Receipts (“ADRs”) between March 24, 2025 and March 12, 2026.

According to the complaint, during the class period, defendants concealed and misrepresented the status and prospects of the TACTI-004 trial based on continuing positive efficacy and safety readouts of efti’s 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 SEC 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 was aware of or was reckless, based on its 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.
