Brief summary

The goal of this clinical trial is to learn if QL1706 combined with bevacizumab can effectively treat adult female patients (18 to \<75 years old) with newly diagnosed FIGO stage IC-IV advanced ovarian clear cell carcinoma. The main questions it aims to answer are: 1. Does QL1706 combined with bevacizumab, compared to platinum-based chemotherapy, prolong patients' progression-free survival (PFS)? 2. What is the safety profile of QL1706 combined with bevacizumab, such as what medical problems (adverse events) do participants experience? Researchers will compare QL1706 combined with bevacizumab (experimental arm) to a standard chemotherapy regimen of paclitaxel plus carboplatin (control arm) to see if QL1706 combined with bevacizumab is more effective in the first-line treatment of advanced ovarian clear cell carcinoma. Participants will: 1. Be randomly assigned to receive either QL1706 combined with bevacizumab (QL1706 administered every 3 weeks, bevacizumab administered every 3 weeks) or paclitaxel plus carboplatin chemotherapy (administered every 3 weeks). 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.
