The purpose of this study is to assess the efficacy and safety of SG001 plus one of four platinum-based chemotherapy regimens compared to the placebo plus one of four platinum-based chemotherapy regimens in the treatment of adult PD-L1 positive (CPS≥1) women with recurrent, or metastatic cervical cancer. Possible chemotherapy regimens include paclitaxel plus cisplatin with or without bevacizumab and paclitaxel plus carboplatin with or without bevacizumab. The study include two stages: the safety run-in phase and phase Ⅲ trail. Upon completion of the first stage study, the Safety Monitoring Committee (SMC) will decide whether to proceed directly to Phase Ⅲ study.~The primary study hypotheses are that the combination of SG001 plus chemotherapy is superior to placebo plus chemotherapy with respect to: 1) Progression-free Survival (PFS) per Response Evaluation Criteria in Solid Tumors (RECIST 1.1), 2) Overall Survival (OS).
This study is a randomised, double-blind, placebo-controlled, multicentre phase 3 clinical study to evaluate the efficacy and safety of SG001 plus chemotherapy±bevacizumab versus placebo plus chemotherapy±bevacizumab, as first-line treatment, in patients with PD-L1 positive (CPS≥1), Recurrent or Metastatic Cervical Cancer. The study contains a Safety Lead-in Phase in which the safety and tolerability of SG001＋Chemotherapy±Bevacizumab will be assessed prior to the Phase 3 portion of the study.
