Brief Summary

This is a phase I-II trial to find the safety and activity of adding a new drug (neratinib) to the usual treatment (radiation combined with male hormone deprivation therapy) in lowering the chance of prostate cancer growing or returning. Niraparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Adding niraparib to the usual care may lower the chance of prostate cancer growing or returning.

Detailed Description

PRIMARY OBJECTIVES:

I. To establish the preferred dose of niraparib in combination with radiation and antiandrogen therapy (ADT). (Phase I) II. To compare the disease-free state, defined as prostate specific antigen (PSA) remaining \< 0.1 ng/ml at the end of ADT therapy in men with high risk prostate cancer treated with standard therapy with or without the addition of niraparib. (Phase IIR)

SECONDARY OBJECTIVES:

I. To further establish the safety and toxicity profile of standard treatment with radiation and androgen deprivation therapy specifically, two years from initiation of ADT, plus niraparib at the phase II dose.

II. To compare the overall survival, prostate cancer-specific survival, local/regional or distant progression, and distant metastatic disease rates of standard therapy with or without the addition of niraparib.

EXPLORATORY OBJECTIVE:

I. To identify genomic biomarkers of response to combination therapy with radiation, ADT and PARP inhibition.

OUTLINE: This is a phase I, dose-escalation study of niraparib, followed by a randomized phase II study.

PHASE I: Patients receive niraparib orally (PO) once daily (QD) and receive standard of care gonadotrophin releasing hormone (GnRH) agonist androgen suppression therapy. Treatment with niraparib continues for 12 months, and GnRH agonist therapy for 24 months in the absence of disease progression or unacceptable toxicity. Beginning 8 weeks after starting niraparib and GnRH agonist, patients undergo standard of care intensity-modulated radiation therapy (IMRT) 5 days per week for about 6-9 weeks, depending on type of radiation therapy given, in the absence of disease progression or unacceptable toxicity. Patients also undergo magnetic resonance imaging (MRI) on study.

PHASE II: Patients are randomized to 1 of 2 arms:

ARM I: Patients undergo standard of care GnRH agonist androgen suppression therapy for 24 months in the absence of disease progression or unacceptable toxicity. Beginning 8-28 weeks after starting GnRH agonist, patients undergo IMRT 5 days per week for about 6-9 weeks depending on type of radiation therapy given in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI on study.

ARM II: Patients undergo standard of care GnRH agonist androgen suppression therapy for 24 months, and niraparib PO QD for 12 months in the absence of disease progression or unacceptable toxicity. Beginning 8 weeks after starting niraparib, patients undergo standard of care IMRT 5 days per week for about 6-9 weeks depending on type of radiation therapy given in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI on study.

After completion of study treatment, patients are followed up every 6 months for 3 years, then annually for 3 years.

Primary Outcome Measures
NameTimeMethod
Maintenance of disease-free stateUp to 2 years following the start of antiandrogen therapy

Will be characterized by PSA values sustained below 0.1 ng/ml until the completion of treatment. A modified intent-to-treat analysis will be conducted. The proportion of patients disease-free at 24 months will be compared in the two treatment arms using a non continuity-corrected chi-square test. As a secondary analysis, a logistic regression model will be fit to adjust for the stratification factors (risk group and type of radiation therapy).

Secondary Outcome Measures
NameTimeMethod
Overall survivalFrom randomization until death from any cause, assessed up to 3 years

Will consist of comparison of Kaplan-Meier (Kaplan 1958) curves using a logrank test.

Prostate cancer-specific survivalFrom randomization until death from prostate cancer, assessed up to 3 years

Will consist of comparison of Kaplan-Meier (Kaplan 1958) curves using a logrank test.

Time to local/regional or distant progressionUp to 3 years

Cumulative incidence curves will be compared using the Fine-Gray test (Dignam 2008).

Pathologic complete response (pCR)At 24 months

Will be assessed among patients undergoing 12-core biopsy. Will be compared using a chi-square test.

Time to distant metastasesFrom randomization until detection of distant metastatic disease, assessed up to 3 years

Cumulative incidence curves will be compared using the Fine-Gray test (Dignam 2008).

Biochemical progression-free survivalUp to 3 years

Will be defined as PSA \>= 2 ng/ml over the nadir PSA, the presence of local, regional, or distant recurrence, or death from prostate cancer. Will consist of comparison of Kaplan-Meier (Kaplan 1958) curves using a logrank test.

Incidence of adverse events (Phase II)Up to 3 years

Adverse event (AE) rates in the two treatment arms will be categorized as early (within 90 days of completion of radiotherapy) or late (more than 90 days after the completion of radiotherapy). type, grade, and attribution to treatment. For each type of AE, the worst grade occurring during the early treatment period, late treatment period, or entire treatment period will be determined. For each time period, treatment group comparisons will be conducted using chi-square or Fisher exact tests.
