Transgene's TG4001 vaccine for cervical and anogenital cancers failed to meet primary PFS objective in phase 2 trial, but showed a trend towards improvement in cervical cancer subgroup, requiring further analysis. TG4001 uses a Modified Vaccinia virus Ankara vector with HPV E6, E7 antigens, and human IL-2. The company plans a full data analysis before deciding the future of TG4001, while focusing on its other vaccine programs, including TG4050 for head and neck cancer.
