Active clinical trials for "Carcinoma, Ovarian Epithelial"

The purpose of this study is to evaluate the efficacy and safety of prexasertib in women with platinum-resistant or refractory recurrent ovarian cancer.

This is a proof of concept study (a study to initially assess the benefit a new drug indication) of the combination of two investigational drugs cediranib and olaparib in patients with ovarian cancer whose cancer worsened despite previously receiving a poly (ADP-ribose) polymerase (PARP) inhibitor (such as olaparib). The purpose of this study is to find out whether taking cediranib and olaparib at the same time will be able to stop tumors from growing further or shrink it. Cediranib works by blocking (inhibiting) several specific proteins in cancer cells called the vascular endothelial growth factor (VEGF) receptors. These proteins are important in the formation of blood vessels to the tumor. It is believed that many tumors survive because the blood vessels on the tumors bring oxygen and nutrients to the cancer cells which enable them to grow. If the formation of the blood vessels is blocked, the tumor cells may die. Olaparib, works by blocking a protein called poly [adenosine diphosphate-ribose] polymerase (PARP). PARP is an important protein which tries to fix damaged deoxyribonucleic acid (DNA, molecules that contain important instructions for the development of cells). Many cancers are thought to develop from damaged DNA. By blocking PARP from fixing damaged DNA, the tumor cells may die. Adding cediranib to olaparib, and therefore blocking several different mechanisms for cancer growth, may stop tumor growth.

Patients with first recurrent resistance ovarian cancer and disease progression with peritoneal carcinomatosis will undergo PIPAC procedure. The primary end point is to determine the clinical benefit rate (CBR) of a pressurized intraperitoneal aerosol chemotherapy with a combination of cisplatin and doxorubicin.

PARP inhibitors, such as olaparib, significantly improve progression free survival (PFS) in participants with recurrent, platinum-sensitive high-grade serous/endometrioid ovarian cancer (HGS/EOC), who harbour a germline mutation in BRCA 1 or 2 genes. Despite some of the most impressive hazard ratios seen in ovarian oncology, such improvements in PFS have not translated into improved overall survival (OS) advantage potentially because maintenance poly ADP ribose polymerase inhibitors (PARPi) are only being administered during a single remission. Here the investigators will test the feasibility of administering a second course of olaparib in participants who have recurrent platinum-sensitive HGS/EOC.

The purpose of this study is to determine how patients with ovarian, fallopian tube, and primary peritoneal cancer will best respond to treatment with rucaparib versus chemotherapy.

Epithelial ovarian cancer harbours 20% Breast Cancer gene (BRCA)1/2 mutations independently of family history. Poly ADP ribose polymerase (PARP) inhibitors (PARPi) have shown clinical activity among patients with homologous recombination deficiency (HRD) and specifically among BRCA1/2 mutation carriers. The European Medicines Agency (EMA) approved the use of olaparib as maintenance therapy "as monotherapy for the maintenance treatment of adult patients with platinum sensitive relapsed BRCA mutated (germline and/or somatic) high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who are in response (complete response or partial response) to platinum-based chemotherapy". Trabectedin and Pegylated liposomal doxorubicin (PLD) have shown relevant activity in relapsed epithelial ovarian cancer. In the relapse with Treatment-free interval of last platinum (TFIp) between 6 and 12 months this efficacy translated into an increase in Overall survival (OS) and Progression free survival (PFS). There is an increase of hypersensitivity reactions (HSR) among platinum sensitive patients, that reaches 44% in third line and does not always allow for platinum use despite desensitization protocols. In relapse with TFIp between 6-12 months the use of Trabectedin+PLD is accepted in guidelines and consensus. Following clinical BRCAness criteria a group of patients that harbours up to 50% of BRCA1/2 mutations can be selected. Olaparib has been licensed according to EMA for maintenance in BRCA mutated patients after response to platinum following Study 19 phase II trial and further confirmed with phase III SOLO-2 data. However there is no evidence of the benefit of adding olaparib after Trabectedin+PLD response among BRCA1/2 carriers. The combination of Trabectedin+PLD, as well as both single drugs, have shown higher activity among BRCA1/2 carriers.

This is an ongoing Phase 1/2, open-label, multicenter, non-randomized study of MEDI4736 (durvalumab) in subjects with recurrent, platinum-resistant ovarian cancer who are scheduled to receive pegylated liposomal doxorubicin (PLD).The primary objective of Phase 1 is to determine the maximum tolerated dose (MTD) and safety profile, with a secondary objective to evaluate the clinical efficacy as measured by progression-free survival (PFS) rate at 6 months (PFS-6). The primary objective of Phase 2 is the evaluation of clinical efficacy as measured by PFS-6. For both phases, secondary objectives include evaluation of clinical efficacy as measured by overall response rate, PFS, and overall survival (OS), safety and tolerability, and immunological responses.

Multicenter, open-label, randomized, controlled phase III clinical trial to evaluate the activity and safety of PM01183 versus PLD or topotecan as control arm in patients with platinum-resistant ovarian cancer. PM01183 will be explored as single agent in the experimental arm (Arm A) versus PLD or topotecan in the control arm (Arm B).

Study in two stages, and with a sub-study.

This phase II trial is studying how well giving belinostat together with carboplatin works in treating patients with recurrent or persistent ovarian epithelial cancer, fallopian tube cancer, or primary peritoneal cancer that did not respond to carboplatin or cisplatin. Belinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Drugs used in chemotherapy, such as carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving belinostat together with carboplatin may kill more tumor cells.
