Oncolytic Adenovirus Coding for TNFa and IL2 (TILT-123) With Pembrolizumab or Pembrolizumab (Phase 1a) and Pegylated Liposomal Doxorubicin (Phase 1b) as Treatment for Ovarian Cancer.

Summary

This is an open-label, phase 1/1b, dose-escalation, multicenter and multinational trial evaluating the safety of oncolytic adenovirus TILT-123 in combination with Pembrolizumab, or Pembrolizumab and Pegylated Liposomal Doxorubicin in patients with platinum resistant or refractory ovarian cancer.
