ClinConnect Summary

This clinical trial is studying a new treatment called IBI354 for women with advanced ovarian, primary peritoneal, or fallopian tube cancer that has not responded to previous platinum-based chemotherapy. The trial aims to see how well IBI354 works compared to the standard chemotherapy options chosen by doctors, which include drugs like paclitaxel and gemcitabine. Women who are 18 years or older, have been diagnosed with this type of cancer, and have experienced disease progression after their last treatment may be eligible to participate.

If you join the trial, you will be randomly assigned to receive either IBI354 or one of the chemotherapy drugs selected by your doctor. The treatment will be given in cycles, and you will be monitored closely for any side effects and how well the treatment is working. This study is ongoing, and researchers hope to find a more effective option for patients whose cancer is resistant to current treatments. It's important to discuss with your doctor if you're considering participation, as they can help determine if you meet the eligibility criteria and explain what to expect throughout the trial.
