Summary

This trial is testing a new combination of drugs for ovarian cancer. The goal is to see if it is more effective and has fewer side effects than the current standard of care.

Who is the study for?
This trial is for women over 18 with newly diagnosed advanced ovarian cancer, including certain subtypes and related cancers. They should be fit for surgery, have a performance status of 0-1 indicating they are fully active or restricted in physically strenuous activity but ambulatory, and not pregnant. Exclusions include autoimmune disorders, brain metastases, recent malignancies except specific treated cases, ongoing severe side effects from past treatments, cardiovascular disease, prior treatment for ovarian cancer or allergies to the study drugs.
What is being tested?
The study tests Durvalumab combined with chemotherapy (Carboplatin+Paclitaxel) and Bevacizumab versus placebo controls followed by maintenance therapy with Durvalumab and Bevacizumab alone or alongside Olaparib. It's a Phase III trial where patients are randomly assigned to different treatment groups without knowing which one they're receiving.
What are the potential side effects?
Possible side effects include immune-related reactions due to Durvalumab affecting organs like lungs or intestines; high blood pressure from Bevacizumab; bone marrow suppression causing low blood cell counts from chemotherapy; fatigue; nausea; potential allergic reactions to any drug components.
