Hormone-Resistant Prostate Cancer, Prostate Adenocarcinoma, Recurrent Prostate Carcinoma, Stage IV Prostate Cancer
Conditions
Brief summary
This randomized phase II trial studies how well tivantinib works compared to placebo in treating patients with metastatic prostate cancer. Tivantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Detailed description
PRIMARY OBJECTIVES: I. To determine progression-free survival (PFS) in men with minimally symptomatic or asymptomatic metastatic, castrate-resistant, chemotherapy-naïve prostate cancer treated with ARQ 197 (tivantinib). SECONDARY OBJECTIVES: I. To determine the prostate-specific antigen (PSA) response rate at 12 weeks in men with metastatic, castrate-resistant, chemotherapy-naïve prostate cancer treated with ARQ 197. II. To determine the radiographic response rate at 12 weeks based on Response Evaluation Criteria in Solid Tumors (RECIST) criteria on computed tomography (CT) scans and stability of bone lesions on bone scan in castrate-resistant, chemotherapy-naïve prostate cancer treated with ARQ 197. III. To determine the proportion of patients who are progression-free at 12 weeks. IV. To assess safety and tolerability in patients treated with ARQ 197 using the National Institute of Cancer (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 grading of toxicities. TERTIARY OBJECTIVES: I. Evaluate markers of bone turnover. (Exploratory) OUTLINE: Patients are randomized to 1 of 2 treatment arms. Arm I: Patients receive tivantinib orally (PO) twice daily (BID) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Arm II: Patients receive placebo PO BID on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients with disease progression may crossover to Arm I. After completion of study treatment, patients are followed up every 3 months for 6 months.

Proportion of Patients Who Respond
An assumed binomial distribution used. Summarized with their corresponding 95% binomial confidence intervals and compared in an exploratory manner between the two treatment arms. Dichotomized outcomes of response will be descriptively summarized and graphically evaluated using bar graphs.
Time frame: At 12 weeks
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Arm I (Tivantinib) | Proportion of Patients Who Respond | 1.9 percentage of patients |
| Arm II (Placebo) | Proportion of Patients Who Respond | 0 percentage of patients |
| Crossover From Placebo to Tivantinib | Proportion of Patients Who Respond | 8.3 percentage of patients |
PSA Response Rate
Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
Time frame: up to 12 weeks
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Arm I (Tivantinib) | PSA Response Rate | 1.9 percentage of patients |
| Arm II (Placebo) | PSA Response Rate | 0 percentage of patients |
| Crossover From Placebo to Tivantinib | PSA Response Rate | 8.3 percentage of patients |
Change in Bone Specific Alkaline Phosphatase (BSAP) in Serum
BSAP will first be descriptively summarized by treatment group and also evaluated using graphical analyses to assess potential patterns over time and see if changes in bone resorption differ between those who are progression-free at 12 weeks vs. not after treatment with tivantinib. The potential impact of early changes in these markers on PFS using Cox regression models will be also explored.
Time frame: Baseline to up to 6 months
Change in Markers of Bone Turnover in Urine
NTx and CTX will first be descriptively summarized by treatment group and also evaluated using graphical analyses to assess potential patterns over time and see if changes in bone resorption differ between those who are progression-free at 12 weeks vs. not after treatment with tivantinib. The potential impact of early changes in these markers on PFS using Cox regression models will be also explored.
Time frame: Baseline to up to 6 months
Radiographic Response Rate Based on RECIST Criteria
Summarized with their corresponding 95% binomial confidence intervals and compared in an exploratory manner between the two treatment arms. Dichotomized outcomes of response will be descriptively summarized and graphically evaluated using bar graphs.
Time frame: Up to 12 weeks
| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Arm I (Tivantinib) | Radiographic Response Rate Based on RECIST Criteria | 1.9 percentage of patients |
| Arm II (Placebo) | Radiographic Response Rate Based on RECIST Criteria | 0 percentage of patients |
| Crossover From Placebo to Tivantinib | Radiographic Response Rate Based on RECIST Criteria | 8.3 percentage of patients |
