What clinical trials evaluated Zejula (niraparib)?
Zejula (niraparib) was studied in multiple clinical trials across different patient groups, including ovarian cancer settings where PARP inhibitors are used. The company and regulators relied on a mix of randomized phase 3 studies and supportive phase 1/2 data to define safety, dosing, and clinically meaningful outcomes such as tumor response and progression-free survival.
Which Zejula trials are most commonly referenced for approval?
The pivotal evidence for Zejula’s key indications comes from large, controlled late-stage studies plus earlier phase trials that established the dose and safety profile. Trial designs generally evaluated niraparib versus placebo (or standard therapy comparisons depending on the setting) and assessed how long patients remained free from disease progression.
What outcomes did Zejula trials measure?
Across Zejula studies, endpoints typically included:
- Progression-free survival (how long patients live without the cancer worsening)
- Objective response rate (how often tumors shrink or disappear)
- Safety and tolerability (including dose interruptions or adjustments)
These outcomes are standard for ovarian cancer trials and align with how regulators typically evaluate PARP inhibitors.
Are there trials in newly diagnosed vs. relapsed ovarian cancer?
Zejula has been evaluated in multiple phases of ovarian cancer care, including relapsed settings and consolidation approaches after initial response to chemotherapy. Many PARP inhibitor trials are designed to test benefit in specific disease states such as platinum-sensitive relapse and maintenance/consolidation after response to platinum-based therapy.
What are common dosing/safety issues discussed in Zejula trials?
Across PARP inhibitor studies, safety monitoring is a central part of trial reporting. For niraparib specifically, clinicians focus on treatment-emergent side effects and how often patients need dose holds, reductions, or supportive care. Trial results also inform recommended starting-dose strategies and monitoring practices used in routine care.

If you tell me your indication, I can narrow to the exact trials
“Zejula clinical trials” can mean different studies depending on the ovarian cancer subtype and treatment line (for example, maintenance/consolidation after platinum response vs relapsed platinum-sensitive disease). If you share the indication you care about (or the wording from your prescription/label, or the cancer stage/subtype), I can pinpoint the most relevant trial(s) for that use case and summarize the trial endpoints and results.
