This study aims to explore the safety and efficacy of oral topotecan combined with toripalimab in treating advanced/recurrent endometrial cancer through a single-center, prospective, single-arm, phase II clinical trial. The goal is to explore the first-line treatment options for endometrial cancer patients in the era of immunotherapy, to improve the overall treatment level and prognosis of endometrial cancer.
1. Overall Design This trial is a single-center, prospective, single-arm, phase II clinical trial to evaluate the safety and efficacy of oral topotecan combined with toripalimab in treating advanced/recurrent endometrial cancer. 2. Experimental observation indicators 1) Main indicators: progression-free survival (PFS), 2) Other indicators: overall survival (OS), objective response rate (ORR), adverse reactions, changes in immune-related factors and biomarkers 3. Sample size calculation This clinical trial aims to evaluate the safety and efficacy of oral topotecan combined with toripalimab in treating advanced/recurrent endometrial cancer patients. Based on literature reports, the median PFS of patients with advanced/recurrent endometrial cancer is 3.8 months. In comparison, the experimental group is expected to have a median PFS of 7 months, with an alpha value of 0.05. Follow-up for 1 year is conducted, considering a 10% dropout rate. This study plans to include 30 patients with advanced/recurrent endometrial cancer. Mid-term analysis: Expected ORR not less than 15%, with a minimum of 19 enrolled cases for mid-term analysis (at least 3 cases of CR or PR) 4. Methods Topotecan, 1.4mg/㎡, orally administered, d1-5+toripalimab 240mg, intravenous drip, d1, q3w, until disease progression or toxicity intolerance. 5. Data Processing Enter data and use SPSS statistical software for statistical analysis. Statistical analyst: Clinical Statistics Department of Fudan University Cancer Hospital. Mailing address: 270 Dong'an Road, Shanghai.
