COMPLAINT ALLEGATION SUMMARY:
Immutep is a biotechnology company that was conducting its TACTI-004 Phase III trial evaluating eftilagimod alfa (“efti”) as a treatment for patients with advanced lung cancer.
The complaint alleges that, throughout the Class Period, Defendants made materially false and/or misleading statements, as well as failed to disclose material facts about the company’s business, operations, and prospects. Specifically, Defendants misrepresented and/or failed to disclose that: (1) the company misrepresented the TACTI-004 trial status and prospects based on efti’s performance in prior studies; (2) the existing information for the TACTI-004 trial indicated that there was a risk it would fail to meet its primary efficacy and/or safety endpoints; and (3) as a result of the foregoing, Defendants’ statements about the company’s business, operations, and prospects were materially false and misleading and/or lacked a reasonable basis at all relevant times.
WHY DID IMMUTEP’S STOCK DROP?
On March 13, 2026, Immutep announced that the Independent Data Monitoring for the TACTI-004 study recommended that the trial be discontinued following a planned interim futility analysis. On this news, the price of Immutep’s stock fell about 83%.
THE LEAD PLAINTIFF PROCESS:
The Private Securities Litigation Reform Act of 1995 permits any investor who purchased or acquired Immutep ADRs during the Class Period to seek appointment as lead plaintiff in the Immutep class action lawsuit. A lead plaintiff is a representative party that acts on behalf of other class members in directing the litigation. In order to be appointed lead plaintiff, the Court must determine that the class member’s claim is typical of the claims of other class members, and that the class member will adequately represent the class. Your ability to share in any recovery is not, however, affected by the decision whether or not to serve as a lead plaintiff. Filling out the online form above or communicating with any counsel is not necessary to participate or share in any recovery achieved in this case. Any member of the purported class may move the court to serve as a lead plaintiff through counsel of his/her choice, or may choose to do nothing and remain an inactive class member.
