Clinical summary
Summary
Eligible patients will be randomised to receive 200mg or niraparib or a niraparib-placebo, in addition to 1000mg of abiraterone acetate and 5mg of prednisone once daily.
Conditions
This trial is treating people with castrate sensitive prostate cancer
Eligibility
Inclusion
- Pathological diagnosis of prostate adenocarcinoma
- Must have appropriate deleterious homologous recombination repair (HRR) gene alteration
- Metastatic disease as documented by conventional imaging with computed tomography (CT) or magnetic resonance imaging (MRI) (for soft tissue lesions) or 99mTc bone scan (for bone lesions). Participants with a single bone lesion on Technetium-99m (99mTc) bone scan with no other non-nodal metastatic disease must have confirmation of bone metastasis by CT or MRI. Participants with lymph node-only disease are not eligible
- Androgen deprivation therapy (either medical or surgical castration) must have been started >=14 days prior to randomization and participants be willing to continue androgen deprivation therapy (ADT) through the treatment phase
- Other allowed prior therapy for metastatic castration-sensitive prostate cancer (mCSPC): (a) maximum of 1 course of radiation and 1 surgical intervention for symptomatic control of prostate cancer (example, uncontrolled pain, impending spinal cord compression or obstructive symptoms). Participants with radiation or surgical interventions to all known sites of metastatic disease will be excluded from trial participation. Radiation must be completed prior to randomization (b) Up to a maximum of 6 months of ADT prior to randomization; (c) Up to a maximum of 45 days of abiraterone acetate + prednisone (AA-P) prior to randomization (d) Up to a maximum of 2 weeks of ketoconazole for prostate cancer prior to randomization
Exclusion
- Prior treatment with a poly (adenosine diphosphate-ribose) polymerase inhibitor (PARP inhibitor)
- History of adrenal dysfunction
- Long-term use of systemically administered corticosteroids (greater than [>] 5 milligrams [mg] of prednisone or the equivalent) during the study is not allowed. Short-term use (<=4 weeks, including taper) and locally administered steroids (for example, inhaled, topical, ophthalmic, and intra-articular) are allowed, if clinically indicated
- History or current diagnosis of myelodysplastic syndrome (MDS)/ acute myeloid leukemia (AML)
Inclusion
- Your cancer has spread to other parts of the body (metastatic) or has grown into nearby parts of the body (locally advanced).
- You are currently receiving treatment for your cancer.
Exclusion
- You have been diagnosed with a prior or secondary type of cancer.
- You have certain types of non-cancer medical conditions.
- You have had certain treatments, surgical procedures or drugs.
Clinical trials have complex eligibility criteria, and other criteria may apply for this trial. Ask your doctor about whether this trial could be right for you.
