NCT04577833

Brief Summary

The purpose of this study is to determine the relative bioavailability (rBA; Period 1) and bioequivalence (BE; Period 2 and 3) of various strengths and formulations of niraparib and abiraterone acetate (AA) at steady state under modified fasted conditions in participants with metastatic castration-resistant prostate cancer (mCRPC).

Outcome Measures

Primary Outcomes (4)

  • Maximum Observed Analyte Concentration at Steady State (Cmax,ss) of Niraparib and Abiraterone Acetate (AA) [Period 2 and Period 3]

    Cmax,ss is defined as maximum observed analyte concentration at steady state.

    Predose, up to 10 hour post dose

  • Area Under the Plasma Concentration-time Curve from Time Zero to 24 Hours at Steady State (AUC [0-24h],ss) of Niraparib and AA (Period 2 and Period 3)

    AUC (0-24h),ss is defined as area under the plasma concentration-time curve from time zero to 24 hours at steady state.

    Predose, up to 24 hours post dose

  • Ratio of Individual Cmax,ss Values Between Test and Reference Treatment (Period 2 and Period 3)

    Ratio of individual Cmax,ss values between test and reference treatment will be assessed.

    Predose, up to 10 hours post dose

  • Ratio of individual AUC (0-24h),ss Values Between Test and Reference Treatment (Period 2 and Period 3)

    Ratio of individual AUC (0-24h),ss values between test and reference treatment will be assessed.

    Predose, up to 24 hours post dose

Secondary Outcomes (7)

  • Maximum Observed Analyte Concentration at (Cmax) of Niraparib and AA (Period 1)

    Predose, up to 72 hours post dose

  • Area Under the Plasma Concentration-time Curve from Time Zero to 72 Hours (AUC [0-72h]) of Niraparib and AA (Period 1)

    Predose, up to 72 hours post dose

  • Ratio of individual AUC (0-72h) Values Between Test and Reference Treatment (Period 1)

    Predose, up to 72 hours post dose

  • Serum Testosterone Level

    Predose on Day -7, Day 11, Day 12 and Day 23

  • Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability

    From study start until study completion (up to 3.1 years)

  • +2 more secondary outcomes

Study Arms (4)

Treatment Sequence ABD

EXPERIMENTAL

Participants will receive single doses of niraparib and abiraterone acetate (AA) using niraparib Formulation 1 as Treatment A in Treatment Period 1, followed by multiple doses of niraparib and AA using niraparib Formulation 2 as Treatment B in Treatment Period 2, followed by multiple doses of niraparib and AA using niraparib Formulation 4 as Treatment D in Treatment Period 3. From Period 2 onwards and during Extension and Long-term Extension Phases, all participants will continue to receive treatment with niraparib and AA-prednisone (AAP) or AAP alone.

Eligibility Criteria

Age18 Years+
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically or cytologically confirmed adenocarcinoma of the prostate
  • Diagnosed with metastatic castration-resistant prostate cancer (mCRPC), who in the opinion of the investigator may benefit from treatment in this study
  • Able to continue gonadotropin-releasing hormone analogues (GnRHa) therapy during the study if not surgically castrate (that is, participants who have not undergone bilateral orchiectomy)
  • Eastern Cooperative Oncology Group Performance Status (ECOG PS) of less than or equal to (\<=) 1
  • Willing to provide a tumor sample (archival) for determination of homologous recombination repair (HRR) gene alteration status

You may not qualify if:

  • Symptomatic brain metastases
  • Prior disease progression during treatment with abiraterone acetate (AA) alone or when combined with a poly adenosine diphosphate (ADP)-ribose polymerase inhibitor (PARPi). Prior discontinuation of treatment with AA or PARPi due to AA- or PARPi related toxicity.
  • History or current diagnosis of myelodysplastic syndrome (MDS)/ acute myeloid leukemia (AML)
  • Known allergies, hypersensitivity, or intolerance to niraparib or AA or the corresponding excipients of niraparib/AA
  • Any medical condition that would make prednisone/prednisolone use contraindicated
