A Study of QL1706 (an Anti-PD-1/CTLA-4 Combined Antibody) Combined With Albumin-bound Paclitaxel and Bevacizumab in the Treatment of Platinum-resistant Recurrent Ovarian Cancer

"The Order of Drug Administration was: QL1706→ bevacizumab → albumin-binding paclitaxel, and each drug was administered at least 30 minutes apart.~QL1706: 5 mg/kg Q3W. The infusion time was 30 minutes + 5 minutes. No dose adjustment was allowed for QL1706 during treatment, but delayed administration was allowed, with a delay of no more than 4 weeks from the previous dose.~Albumin-binding paclitaxel: 260 mg/m 2 Q3W, IV, for 30 min + 5 min. During treatment, albumin-binding paclitaxel allows for dose adjustments.~Bevacizumab: 15 mg/kg Q3 W, iv. The first infusion should last 90 minutes. If the first infusion was well tolerated, the second infusion could be shortened to 60 minutes. If the patient is also well-tolerated for a 60-minute infusion, then all subsequent infusions can be completed in 30 minutes, no dose adjustment is allowed for bevacizumab."
