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.

Inclusion criteria

* Patients must have histologically documented adenocarcinoma of the prostate with progressive systemic disease (either rising PSA or progression of disease on CT scan or magnetic resonance imaging \[MRI\] or bone scan) despite castrate levels of testosterone due to orchiectomy or luteinizing hormone-releasing hormone (LHRH) agonist or antagonist; castrate levels of testosterone must be maintained throughout the study * Evidence of metastatic disease on CT or bone imaging * Patients must have demonstrated evidence of progressive disease since the most recent change in therapy; progressive disease is defined as any one of the following (measurable disease, bone scan, or PSA progression): * Measurable disease progression: objective evidence of increase \> 20% in the sum of the longest diameters (LD) of target lesions from the time of maximal regression or the appearance of one or more new lesions * Bone scan progression: appearance of two or more new lesions on bone scan attributable to prostate cancer will constitute progression * PSA progression: two successive rises from baseline PSA separated at least by one week with the last value \>= 2 ng/mL * Asymptomatic or minimally symptomatic from prostate cancer - no symptoms attributed to prostate cancer greater than grade I using NCI CTCAE version 4.0 grading of toxicities * Secondary hormonal therapies (e.g., abiraterone acetate, flutamide, estrogen) must be discontinued for at least 4 weeks prior to study enrollment unless the duration of the therapy was less than 8 weeks and there was no demonstrated decrease in PSA * Secondary hormonal therapies with bicalutamide or nilutamide must be discontinued for 6 weeks unless duration of therapy was less than 8 weeks and there was no demonstrated PSA decrease * Prior abiraterone (or investigational anti-androgen) use is allowed; these too will need to be discontinued at least 4 weeks prior to study enrollment * PSA prior to treatment must be \>= 2 ng/ml * Castrate testosterone level (\< 50 ng/dL) * Eastern Cooperative Oncology Group (ECOG) performance status =\< 2 (Karnofsky \>= 60%) * No prior chemotherapy unless utilized in neoadjuvant/adjuvant setting and must have completed \> 6 months prior to enrollment * Four weeks since major surgery or radiation therapy * Absolute neutrophil count \>= 1,500/mcL * Platelets \>= 100,000/mcL * Total bilirubin within normal institutional limits * Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase \[SGPT\]) =\< 2.0 X institutional upper limit of normal * Creatinine within normal institutional limits OR creatinine clearance \>= 40 mL/min/1.73 m\^2 for patients with creatinine levels above institutional normal * Patients must have signed an informed consent document stating that they understand the investigational nature of the proposed treatment * Men and any female partners of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control) prior to study entry and for the duration of study participation and for additional 2 months after finishing therapy; should a patient's sexual partner become pregnant or suspect she is pregnant while patient is participating in this study, he should inform the treating physician immediately * Bisphosphonate or denosumab therapy is permitted provided patients began therapy prior to registration and that they continue them as per the manufacturer's guidelines and/or per institutional practice; patients not taking ongoing bisphosphonate or denosumab therapy will not be permitted to start such therapy until they have completed 12 weeks of study treatment * Patients must be able to swallow pills to participate in the study

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

ArmMeasureValue (NUMBER)
Arm I (Tivantinib)Proportion of Patients Who Respond1.9 percentage of patients
Arm II (Placebo)Proportion of Patients Who Respond0 percentage of patients
Crossover From Placebo to TivantinibProportion of Patients Who Respond8.3 percentage of patients
Secondary

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

ArmMeasureValue (NUMBER)

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

Other Pre-specified

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.
