This study is being done to learn more about how durvalumab and olaparib, when combined with standard of care chemotherapy, could improve outcomes for women with endometrial cancer. This study will also serve to better understand endometrial cancer and associated health problems.
Durvalumab is a type of anti-cancer drug called immunotherapy that targets cancer cells by blocking the signal that prevents the immune system from seeing the cancer cell. Your immune system can then attack and kill the cancer cells.
Olaparib is a type of drug called a PARP (poly [adenosine diphosphate-ribose] polymerase) inhibitor. PARP inhibitors can destroy cancer cells that are not good at repairing DNA damage. Olaparib is taken orally in tablet form. Olaparib is approved by the FDA and in other countries for maintenance treatment for recurrent, epithelial ovarian, fallopian tube or primary peritoneal adult cancer, regardless of BRCA status.
Durvalumab and Olaparib are still in the development stage for the treatment of endometrial cancer, and they are not approved by the Food and Drug Administration (FDA) for treatment of endometrial cancer. Therefore, both these medicines are considered as experimental treatments for patients with endometrial cancer.
The untested parts of the study are the addition of durvalumab to chemotherapy and the addition of durvalumab with or without olaparib following chemotherapy.
Participants will be given one of three different treatments:
- Standard of care chemotherapy
- Durvalumab with chemotherapy followed by Durvalumab
- Durvalumab with chemotherapy followed by Durvalumab and Olaparib
