Beijing, Beijing MunicipalityAges 18 years+ - NCT07472140RecruitingPhase 2/Phase 3
PARP inhibitor with or without anti-angiogenesis drug for ovarian cancer
This trial tests whether adding a drug that blocks blood vessel growth (angiogenesis inhibitor) to a PARP inhibitor works better than the PARP inhibitor alone for ovarian, fallopian-tube, or peritoneal cancers that have a specific DNA repair problem called HRD. It aims to find a more effective treatment for people with these cancers.
Minsk, LesnoyAges 18–75 - NCT00488878Recruiting
Collecting information for certain low-grade ovarian or peritoneal tumors
This study collects health information from people whose ovarian or peritoneal cancer started as a low-grade type but later changed to a higher-grade cancer. It may help researchers better understand how these tumors progress and what to expect over time.
Houston, TexasAges Any age - NCT05071937RecruitingPhase 2
Talazoparib plus ZEN003694 for recurrent ovarian cancer
This Phase 2 trial tests whether combining ZEN003694 with talazoparib can slow or shrink recurrent ovarian, fallopian tube, or primary peritoneal cancer. It is designed for people who have already been treated with a PARP inhibitor before, and it may help if that cancer comes back.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT06366490RecruitingPhase 1
Personalized vaccine for recurrent ovarian cancer
This trial tests a personalized cancer vaccine made from your own tumor cells. It is for women with advanced ovarian, fallopian tube, or primary peritoneal cancer that has returned after at least one round of platinum chemotherapy.
Duarte, CaliforniaAges 18 years+ - NCT07480954RecruitingPhase 1/Phase 2
CAR-NK cell therapy for recurrent ovarian cancer
This trial tests a new type of immune cell therapy (CAR-NK cells) that targets two proteins often found on ovarian cancer cells. It is for people whose cancer has come back after at least two prior treatments.
Shenzhen, GuangdongAges 18–75 - NCT07617753RecruitingPhase 1/Phase 2
CAR-NK Cell Therapy for Recurrent Ovarian Cancer
This trial tests a new type of cell therapy using modified natural killer cells (CAR-NK cells) that are trained to attack ovarian cancer cells. It's designed for patients whose cancer has come back or stopped responding to previous treatments.
Shenzhen, GuangdongAges 18–75 - NCT06511037RecruitingEarly Phase 1
Dye injection to help see cancer during belly surgery
This study tests a special dye, called pafolacianine, that is injected before surgery to help surgeons see hidden cancer spots in the belly during the operation. The goal is to see if using this dye improves how completely the cancer is removed in people with gastrointestinal cancer that has spread to the belly lining.
Orange, CaliforniaAges 18 years+ - NCT04055649RecruitingPhase 2
Test of ONC201 and weekly paclitaxel for platinum-resistant ovarian cancer
This Phase 2 study tests whether ONC201 given with weekly paclitaxel can control platinum-resistant ovarian, fallopian tube, or primary peritoneal cancer. It may help by shrinking tumors or slowing growth in people whose cancer has progressed after platinum chemotherapy.
Detroit, MichiganAges 18 years+ - NCT07022535RecruitingPhase 2
Personalized timing of surgery for advanced ovarian cancer
This trial checks if adjusting the timing of surgery (interval debulking surgery) after chemotherapy can improve outcomes for people with advanced ovarian cancer. It's for those who cannot have surgery right away and will receive chemotherapy first.
Hong KongAges 18 years+ - NCT06735326RecruitingPhase 2
Fluzoparib and Bevacizumab Before Surgery for Advanced Ovarian Cancer
This trial tests whether combining fluzoparib (a PARP inhibitor) with or without bevacizumab (a blood vessel growth blocker) before surgery can shrink advanced ovarian cancer. It is for women with a BRCA gene mutation whose cancer cannot be fully removed with surgery right now.
Jinan, ShandongAges 18 years+ - NCT05737303RecruitingPhase 3
First-line chemotherapy comparison for advanced ovarian cancer
