A Trial of Niraparib in Platinum-Sensitive Castration-Resistant Prostate Cancer With DNA Repair Defects
United States11 participantsStarted 2020-10-19
Plain-language summary
This study is designed to evaluate the initial safety and effectiveness of an investigational drug, niraparib, given to patients who have recently received platinum-based chemotherapy for the treatment of prostate cancer. The study enrolls participants with history of advanced prostate cancer that is growing despite standard hormonal therapies, such as androgen-deprivation therapy.

Inclusion criteria
. Histologically or cytologically confirmed diagnosis of prostate adenocarcinoma (mixed histology will be acceptable, but pure small cell histology is to be excluded).
. ≥ 18 years of age.
. No prior therapy with PARP inhibitor therapy.
. Patients must have received at least 9 weeks of platinum-based chemotherapy for the treatment of mCRPC as the proximal treatment regimen prior to study screening. Patients must not have evidence of clinical or radiographic disease progression (per Investigator assessment) and should have adequately recovered from chemotherapy-related toxicities (at least 4 weeks following completion of chemotherapy, with treatment-related toxicities ≤ grade 1 per CTCAE version 5).
. ECOG performance status of ≤ 2.
. Documented evidence of a pathogenic or likely pathogenic DNA repair aberration in BRCA1/2, ATM, FANCA, PALB2, CHEK2, HDAC2, or BRIP1 through either somatic or germline testing from a CLIA certified laboratory.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Radiographic evidence for metastatic disease. Measureable disease (per RECIST) is not required for enrollment. (i.e. bone-only metastatic disease is permitted).
. Patients with history of treated brain metastases are eligible if off systemic corticosteroids for at least 2 weeks.
Exclusion criteria
. Prior therapy with a PARP inhibitor.
. Presence of clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke (\< 6 months prior to enrollment), myocardial infarction (\< 6 months prior to enrollment), unstable angina, congestive heart failure (≥ New York Heart Association Classification Class II), or serious cardiac arrhythmia requiring medication.
. Presence of known significant immunodeficiency, as determined by the treating investigator.
. Presence of clinically significant active infections, as determined by the treating investigator.
. Known allergy to niraparib or any of its components.
. Prostate cancer with histologic evidence for pure small cell histology
