Olaparib is a medication used in this clinical trial. It is designed to help patients who have completed a previous oncology study and are still benefiting from the treatment. Olaparib works by interfering with the cancer cells’ ability to repair their DNA, which can help to slow down or stop the growth of cancer. This trial aims to continue providing Olaparib to patients who are experiencing positive effects, while also monitoring their safety and how well they tolerate the medication.

BRCA Mutated Ovarian Cancer – This type of ovarian cancer occurs in individuals with mutations in the BRCA1 or BRCA2 genes. These mutations can lead to the development of cancer in the cells of the ovaries. The disease often progresses with the growth of tumors in the ovarian tissue, which may spread to other parts of the body if not managed.

Epithelial Ovarian Cancer – This is the most common form of ovarian cancer, originating in the layer of cells covering the ovaries. It typically begins with abnormal cell growth in the ovarian epithelium. As the disease progresses, these cells can form tumors and potentially spread to nearby organs.

Metastatic Breast Cancer – Also known as stage IV breast cancer, this condition occurs when cancer cells from the breast spread to other parts of the body. The disease progresses as these cells invade distant organs such as the bones, liver, or lungs. It is characterized by the growth of secondary tumors in these areas.

Platinum Sensitive Relapsed Ovarian Cancer – This type of ovarian cancer refers to cases where the disease returns after initial treatment with platinum-based chemotherapy. The cancer is considered “platinum-sensitive” if it responds to this treatment again. The progression involves the recurrence of tumors in the ovaries or other areas.

gBRCA Mutated Metastatic Pancreatic Cancer – This form of pancreatic cancer is associated with inherited mutations in the BRCA1 or BRCA2 genes. It progresses as cancer cells spread from the pancreas to other parts of the body. The disease is marked by the development of tumors in the pancreas and potentially other organs.

Prostate Cancer – This cancer develops in the prostate gland, which is part of the male reproductive system. It often begins with slow-growing tumors that may not cause symptoms initially. As it progresses, the cancer can spread to nearby tissues or distant parts of the body.

Endometrial Cancer – This type of cancer originates in the lining of the uterus, known as the endometrium. It typically starts with abnormal cell growth in this lining. The disease progresses as these cells form tumors, which can invade the uterine wall and potentially spread to other areas.
