Background of the investigation

On March 13, 2026, Immutep Limited announced that the Independent Data Monitoring Committee (IDMC) recommended discontinuation of the Company’s Phase III TACTI-004 clinical trial evaluating eftilagimod alfa (“efti”) in combination with KEYTRUDA and chemotherapy for first-line non-small cell lung cancer.

The Company disclosed that the recommendation followed a planned interim futility analysis, indicating that the trial was unlikely to achieve its primary endpoints.

Following this disclosure, the price of Immutep stock declined approximately 85–90% in a single trading session.

In light of this disclosure, Johnson Fistel is investigating whether Immutep complied with the federal securities laws. If you suffered losses from your investment in Immutep stock, contact Johnson Fistel.
