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 Exclusion Criteria: - Patients who have radiotherapy within 4 weeks or chemotherapy prior to entering the study or those who have not recovered (resolution to grade 1) from adverse events due to agents administered more than 4 weeks earlier; neoadjuvant/adjuvant chemotherapy for local disease is allowed if greater than 6 months have elapsed - Previous hepatocyte growth factor receptor (C-MET) inhibitor treatment (either monoclonal antibody to C-MET or human growth factor [HGF] or small molecule inhibitory to C-MET) - History of allergic reactions attributed to compounds of similar chemical or biologic composition ARQ 197 - Caution should be used with patients receiving inhibitors of cytochrome P450 family 2, subfamily C, polypeptide 19 (CYP2C19) and strong inhibitors of cytochrome P450 family 3, subfamily A, polypeptide4 (CYP3A4); additional hematologic testing will be advised if the medication cannot be substituted - Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or known psychiatric illness/social situations that would limit compliance with study requirements - Known brain metastasis - Current, recent (within 4 weeks of the first study drug administration), or concurrent planned participation in another investigational therapeutic study - Patients with a "currently active" second malignancy other than non-melanoma skin cancers are not to be registered; patients are not considered to have a "currently active" malignancy if they have completed therapy and are now considered to be at less than 30% risk for relapse (by their physician) - Patients may continue on a daily multi-vitamin and calcium/vitamin D supplements;

QRS prolongation or bundle branch block (QRS >= 120 ms), or QT prolongation (per institutional standard of care: Fridericia corrected QT interval [QTcF] or Bazett corrected QT interval [QTcB] >= 470 ms); other ECG abnormalities will need consideration by the treating investigator and enrollment is up to his/her discretion - Presence of non-healing wound, active ulcer, or untreated bone fracture - Known diabetics that have poorly controlled diabetes mellitus (glycated hemoglobin [HbA1c] >= 8.0%) or fasting glucose level >= 189 mg/dL (diabetic patient);

Additional Information

Official title A Randomized, Double-Blind, Placebo-Controlled Phase II Study of ARQ 197 (Tivantinib) in Men With Asymptomatic or Minimally Symptomatic Metastatic Castrate Resistant Prostate Cancer
Principal investigator J. Monk
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.
