Active clinical trials for "Carcinoma, Ovarian Epithelial"

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.

Combination-type oral contraceptives (COCs) have been shown to significantly reduce the risk of invasive epithelial ovarian cancer (IEOC); this protective effect may be achieved to a large extent through COCs ability to reduce cell proliferation in the fallopian tube fimbriae (FTF). The progestin-releasing Mirena® intra-uterine device (IUD) is an increasingly popular method of contraception, but it is not known if its use will reduce a woman's risk of IEOC. Mirena® use does not block ovulation in most women but it may release sufficient progestin to also reduce cell proliferation in the FTF. This study aims to evaluate the effects of the Mirena® IUD on cell proliferation in the FTF as a possible biomarker of protection against IEOC.

Randomized, Double-Blind, Phase III Trial of Olaparib vs. Placebo in Patients with Advanced FIGO Stage IIIB - IV High Grade Serous or Endometrioid Ovarian, Fallopian Tube, or Peritoneal Cancer treated with standard First-Line Treatment, Combining Platinum-Taxane Chemotherapy and Bevacizumab Concurrent with Chemotherapy and in Maintenance.

The OvIP1 study is designed to examine how drug dose and perfusion temperature affect the pharmacokinetics and pharmacodynamics of cisplatin used as (hyperthermic) intraperitoneal chemoperfusion, as an adjunct to surgery, in women with stage III epithelial ovarian cancer.

The investigators propose to evaluate the feasibility, safety, and preliminary efficacy of delivering online, adaptive magnetic resonance imaging (MRI)-guided and gated stereotactic body radiation therapy for patients with recurrent or metastatic ovarian cancer on a novel, integrated Co-60 MRI treatment machine. To best assess this technology, the investigators will focus on patients that have no more than three sites of progressive disease within the central thorax, liver, and/or non-liver abdominopelvis to receive adaptive, MRI-guided and gated SBRT with MRI simulation. Patients will be treated in five fractions over one to two weeks. By adhering to strict normal tissue constraints, expected toxicity will be within the current standard of care but will allow adaptation based on daily anatomic changes. The prescription dose will be determined based on hard normal tissue constraints, and capped at 10Gy per fraction. Although the long term goal will be to achieve improved local control and disease-free survival with reduced toxicity, the present study will be driven by the short term goal of demonstrating the feasibility of this novel treatment approach for recurrent or metastatic ovarian cancer.

This pilot research trial studies folate receptor in diagnosing ovarian cancer using serum samples from patients with a newly diagnosed pelvic mass or previously diagnosed ovarian cancer. Studying samples of serum from patients with ovarian cancer in the laboratory may help understand the use of folate receptor induction as a clinical tool in initial diagnosis, surveillance, and recurrence.

The purpose of this study is to see if patients undergoing a laparoscopic surgery for removal of ovarian, fallopian tube, or primary peritoneal cancer following neoadjuvant chemotherapy (neoadjuvant- chemotherapy given before surgery) is feasible, safe, and provides similar outcomes as compared to undergoing a large abdominal incision. Minimally invasive, or laparoscopic, surgery is a type of surgery where only small incisions are made on the abdomen and surgical instruments are placed through these incisions to perform the surgery. This type of surgery has been shown to improve outcomes in many types of surgery, including in gynecologic cancer surgery. Specifically, researchers know that patients who have minimally invasive surgery have less pain after surgery, can go home quicker from the hospital, healing time is more rapid, and potentially this can translate into returning to chemotherapy sooner. Specifically, in ovarian, fallopian tube, and primary peritoneal cancer, minimally invasive surgery has not been used as much because these cancers can have tumors all throughout the inside of the abdomen (i.e. wide tumor burden) and located in areas that are sometimes not easily reachable with laparoscopic instruments. However, the reason patients receive neoadjuvant chemotherapy is to shrink the tumor/s to make the surgery less extensive and the recovery easier. It is unknown if minimally invasive surgery can be used in this setting and by studying this, the study team will be able to determine if patient outcomes are improved by implementing (using) this surgical technique.

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.

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).
