Phase III Study of Socazolimab as First-Line Treatment in Persistent, Recurrent, or Metastatic Cervical Cancer

Recruiting now · Phase 3 · Has a placebo group

Conditions studied: Cervical Cancer

In brief

The goal of this clinical trial is to evaluate the efficacy and safety of Socazolimab combined with chemotherapy with or without bevacizumab as first-Line treatment in persistent, recurrent, or metastatic cervical cancer. The main question it aims to answer is: Does Socazolimab combined with chemotherapy with or without bevacizumab better benefit patients with persistent, recurrent, or metastatic cervical cancer as first-line treatment compared with placebo combined with chemotherapy with or without bevacizumab. Participants will be treated with Socazolimab/placebo + chemotherapy ± bevacizumab) for 6\~8 cycles (Q3w), following maintenance treatment of Socazolimab/placebo (Q3w).
