Immutep is facing a securities class action after its ADRs plummeted 83% following the collapse of the TACTI-004 trial. The lawsuit targets CEO Marc Voigt and other executives for allegedly misleading investors about trial progress while withholding negative interim data. ADRs dropped from $2.76 to $0.48 on March 13, 2026. A court deadline for lead plaintiff appointment is set for July 6, 2026.
