Carcinoma, Ovarian Epithelial

The purpose of this observational study is to learn if a specialized blood test can help predict whether advanced ovarian cancer will return after a patient's initial treatments are finished. Researchers are inviting women who have been diagnosed with stage III or IV epithelial ovarian cancer and have recently completed their first-line treatments, which include surgery and platinum-based chemotherapy. The study focuses on "circulating tumor DNA" (ctDNA), which are tiny fragments of genetic material that cancer cells release into the bloodstream as they break down. Finding these DNA fragments in the blood when a patient appears to be cancer-free on standard tests is known as assessing for minimal residual disease (MRD). Because this is an observational study, participants will receive standard medical care as directed by their doctor. For the research portion, participants will provide blood samples at specific times: at the time of diagnosis, shortly after surgery, right after finishing their first-line chemotherapy, and then every 3 months during regular follow-up visits. Researchers will also analyze a sample of the tumor tissue that was already removed during the patient's standard surgery. By tracking these participants for up to 3 years, researchers hope to discover if the ctDNA test can accurately identify patients who have a high risk of their cancer returning, and if it can detect this earlier than traditional imaging scans or standard blood tests like CA-125.

This is a phase I, open-label, study of BP1001-A in participants with advanced or recurrent solid tumors. The dose escalation phase will determine the safety and the maximum tolerated dose (MTD) or maximum administered dose (MAD) of BP1001-A as a single agent. After the MTD or MAD of BP1001-A is established, the dose expansion phase will commence and determine the safety, toxicity and response of BP1001-A in combination with paclitaxel.

A Clinical and Biological Database will provide to the scientific community a collection of blood and tissues with clinical datas to improve knowledge about cancer and help to develope new cancer treatments. This database is specific to epithetial ovarian cancer, Fallopian tube cancer and Primitive peritoneal cancer.

This is an Italian, multicenter, randomized, open-label phase III trial which will evaluate if Letrozole is superior to standard adjuvant chemotherapy in patients with hormone receptor positive low-grade serous epithelial carcinoma of the ovary (LGSCO). The hypothesis is that letrozole will significantly prolong median progression free survival (PFS) compared with the standard chemotherapy treatment, namely carboplatin AUC 5 and paclitaxel 175 mg/m2.

This is a study of pembrolizumab (MK-3475, KEYTRUDA®) in combination with lenvatinib (E7080) for the treatment of platinum sensitive recurrent ovarian cancer. Participants will receive pembrolizumab and lenvatinib.
