The complaint filed against the NASDAQ-listed firm centers on claims that management violated the Securities Exchange Act of 1934. Specifically, the lawsuit contends that Immutep filed an SEC Form-K on January 30, 2026, characterizing the TACTI-004 trial of its candidate drug, efti, as showing strong operational progress. Plaintiffs argue that this description was materially misleading, as the company allegedly possessed information indicating the trial was failing to achieve its required efficacy benchmarks.
