Cornerstone4 Trial Summary

This trial studies a cancer vaccine to treat advanced ovarian cancer after surgery, with or without chemotherapy.

Who is the study for?
This trial is for patients with advanced stage III ovarian cancer who've had surgery to remove most of the tumor and can start follow-up therapy within 6 weeks. They must have a specific type of tumor (HRP) and be in good health overall, with no severe allergies to rhuGM-CSF, recent cancers except certain skin or epithelial cancers, autoimmune or inflammatory diseases, active infections like TB or hepatitis, HIV, nor be pregnant.Check my eligibility
What is being tested?
The study tests AST-201 (a therapeutic cancer vaccine) combined with rhuGM-CSF versus a placebo plus rhuGM-CSF. Both groups will also receive standard chemotherapy drugs Paclitaxel and Carboplatin. The goal is to see if AST-201 improves outcomes for those with newly diagnosed HRP ovarian cancer after surgery.See study design
What are the potential side effects?
Possible side effects include reactions at the injection site from the vaccine or GM-CSF, allergic responses to any component used in treatment including chemo drugs which may cause nausea, hair loss, blood cell count changes leading to increased infection risk or bleeding problems.
