INVIGORATE: A Study of QL1706 and Bevacizumab in Advanced First-Line Ovarian Clear Cell Carcinoma

Summary

The goal of this phase 3 clinical trial is to evaluate whether QL1706 plus bevacizumab can effectively treat adult female patients (18 to \<75 years old) with newly diagnosed FIGO stage IC-IV ovarian clear cell carcinoma. The main questions it aims to answer are: 1. Does QL1706 plus bevacizumab, compared with standard platinum-based chemotherapy with or without bevacizumab, prolong patients' progression-free survival (PFS)? 2. What is the safety profile of QL1706 followed by QL1706 plus bevacizumab, such as what medical problems (adverse events) do participants experience? Researchers will compare QL1706 followed by QL1706 plus bevacizumab (experimental arm) with standard platinum-based chemotherapy consisting of paclitaxel plus carboplatin with or without bevacizumab (control arm) to see whether QL1706-based immunotherapy is more effective in the first-line treatment of advanced ovarian clear cell carcinoma. Participants will: 1. Be randomly assigned to receive either QL1706 alone during Cycle 1 followed by QL1706 plus bevacizumab from Cycle 2, or paclitaxel plus carboplatin with or without bevacizumab according to prespecified high-risk criteria. 2. Visit the research center regularly for drug infusions, medical examinations (such as vital signs, physical exams, laboratory tests), and tumor imaging assessments. 3. Complete quality of life questionnaires as required.
