Recruiting studies
- NCT03651206RecruitingPhase 2/Phase 3
Study of niraparib and anti–PD-1 for recurrent uterine cancer
This trial studies whether blocking PD-1 (an immune “brake”) along with niraparib (a DNA-repair blocker) can shrink or control recurrent/progressive uterine carcinosarcoma after prior chemotherapy. It’s for people whose cancer has grown again and who meet specific health and lab requirements.
AngersAges 18 years+ - NCT04641247RecruitingPhase 2
Long-term niraparib follow-up for people already benefiting
This study looks at continuing niraparib for a longer time in people who already finished an earlier niraparib trial and are still benefiting. It may help understand how safe and useful long-term treatment is for you.
Tucson, ArizonaAges 18 years+ - NCT05009082RecruitingPhase 3
Niraparib alone or with bevacizumab for advanced ovarian cancer
This trial studies whether niraparib works better when combined with bevacizumab after chemotherapy and surgery for advanced ovarian, fallopian tube, or peritoneal cancer. If you qualify, you may help researchers find a treatment plan that controls the cancer for longer.
AmbergAges 18 years+ - NCT07783022Recruiting
Real-world study of niraparib for ovarian cancer after initial treatment
This study looks at how well niraparib works as maintenance therapy for women with advanced ovarian, fallopian tube, or primary peritoneal cancer who have already responded to initial chemotherapy. It aims to gather real-world data on the treatment's effectiveness and safety.
ShanghaiAges 18 years+ - NCT05718323RecruitingPhase 2
Niraparib with immunotherapy maintenance for advanced small-cell lung cancer
This trial tests whether adding niraparib (a pill cancer medicine) to ongoing immunotherapy maintenance can help people with advanced small-cell lung cancer live longer or better. It is for tumors that show a specific protein marker (SLFN11) and that did not worsen after standard first-line chemo-immunotherapy.
AngersAges 18 years+ - NCT06141265RecruitingPhase 2
Niraparib maintenance after chemo and Avastin for advanced ovarian cancer
This trial tests whether the PARP inhibitor niraparib can help keep advanced ovarian cancer from coming back. You may qualify if you have a BRCA mutation or HRD-positive tumor and finished first-line chemotherapy with bevacizumab (Avastin) with good response.
Beijing, Beijing MunicipalityAges 18–75 - NCT06747845RecruitingPhase 2
Maintenance therapy for stable metastatic pancreatic cancer
This trial tests a combination of two drugs, niraparib and ipilimumab, as a maintenance treatment for people with metastatic pancreatic cancer that has not grown after initial chemotherapy. The goal is to see if this can help keep the cancer stable longer.
Boston, MassachusettsAges 18 years+ - NCT06412120RecruitingPhase 4
Niraparib safety and metabolism study in Black women
This trial tests a new maintenance therapy called niraparib for Black women who have finished initial treatment for advanced ovarian cancer and are in remission or partial response. It aims to see if the drug is safe and how your body processes it.
Fort Lauderdale, FloridaAges 18 years+ - NCT03983226RecruitingPhase 2
Surgery plus niraparib for returning ovarian cancer
This trial tests whether adding niraparib (a pill treatment that targets cancer cell DNA repair) after surgery can help people with ovarian cancer that has come back. It focuses on “platinum-sensitive” cases and tries to remove all visible tumor when possible.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT04716686RecruitingPhase 2
Niraparib alone to help prevent cancer coming back
This Phase 2 study tests niraparib by itself to keep endometrial serous cancer from returning or to control it after chemotherapy helps. It may help some people by targeting tumor DNA repair weaknesses, especially in cancers with certain gene changes.
Jinan, ShandongAges 18 years+ - NCT05990192RecruitingPhase 2
SBRT with or without niraparib for ovarian cancer after PARP inhibitor treatment
This trial tests a new treatment approach for people with ovarian cancer that has started to progress in a few spots (up to 3) after taking a PARP inhibitor. It combines targeted radiation (SBRT) to those spots, followed by another PARP inhibitor (niraparib), to see if this can control the cancer further.
Leeds, LeedsAges 18 years+ - NCT04947254RecruitingPhase 2
Add niraparib to hormone therapy after prostate radiation
This Phase 2 trial tests whether adding niraparib to standard hormone therapy (androgen ablation) after radiation works better for men with high-risk, localized or locally advanced prostate cancer. It may help control the cancer for longer, while also collecting extra tissue and blood to study why the treatment works or doesn’t.
Houston, TexasAges 18 years+ - NCT05183984RecruitingPhase 2
Niraparib plus bevacizumab after complete ovarian cancer surgery
This trial tests whether niraparib, taken after surgery, works better when combined with bevacizumab in people with advanced ovarian, fallopian tube, or primary peritoneal cancer who have no visible tumor left. It also aims to see if this approach helps prevent the cancer from coming back.
AngersAges 18–99 - NCT05526989RecruitingPhase 2
Dostarlimab plus niraparib for advanced penile cancer
This Phase 2 study tests whether combining dostarlimab (an immunotherapy) with niraparib (a cancer pill) can shrink advanced penile cancer and keep it from growing. It may help people whose cancer has progressed after limited prior treatments, and who have not had certain immune therapies before.
Tampa, FloridaAges 18 years+ - NCT05700721RecruitingPhase 2
Niraparib and dostarlimab for cancer with growing brain spots
This trial studies whether the medicines niraparib and dostarlimab can slow advanced cancers that have active, growing brain metastases. It is meant for people whose brain tumors can be measured on MRI and who have had at least one previous treatment.
Houston, TexasAges 18 years+ - NCT05961124RecruitingPhase 2
Lower-dose niraparib to reduce interruptions in ovarian maintenance
This trial tests whether a different starting dose (and adjustments) of niraparib can help people with advanced ovarian (or related) cancer stay on treatment without as many dose interruptions. It’s designed for people who have already finished first-line chemotherapy and whose cancer responded.
Toronto, OntarioAges 18 years+ - NCT06180356RecruitingPhase 2
Niraparib after surgery for ovarian cancer with limited spread
This trial is testing a second course of niraparib (a PARP inhibitor) after surgery for ovarian cancer that has come back in just a few spots. It aims to see if restarting niraparib can help keep the cancer from coming back again.
A CoruñaAges 18 years+ - NCT06594679RecruitingPhase 1/Phase 2
Study of niraparib and abemaciclib for advanced ovarian cancer
This trial tests a combination of two targeted drugs, niraparib and abemaciclib, for people with ovarian, fallopian tube, or primary peritoneal cancer that has come back after at least two prior chemotherapies. It may be an option if you have no standard treatments left and your cancer still responds to platinum-based chemotherapy.
Milan, MilanoAges 18 years+ - NCT06614790Recruiting
Niraparib maintenance for advanced ovarian cancer
This study looks at how well the drug niraparib works as a maintenance treatment for women with advanced ovarian cancer that responded well to initial platinum-based chemotherapy. It may help keep the cancer from coming back.
BialystokAges 18 years+ - NCT06827353Recruiting
Comparing two maintenance drugs for ovarian cancer without DNA repair defects

Common questions
- Are there clinical trials studying Niraparib?
- Yes. Clin2 currently lists 35 recruiting studies that include Niraparib, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Niraparib trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Niraparib an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Niraparib or a specific trial is right for you.
