Tivantinib in Treating Patients With Metastatic Prostate Cancer

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
• 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 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 CYP2C19 and strong inhibitors of 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; all other herbal, alternative, and food supplements (i.e., PC-SPES, Saw Palmetto, St. John wort, etc.) must be discontinued before registration
• New York Heart Association (NYHA) Class III or greater congestive heart failure
• History of myocardial infarction or unstable angina within 6 months prior to initial treatment
• History of severely impaired lung function
• Baseline electrocardiogram (ECG) abnormalities including first degree (PR interval > 210 ms), second degree, or third degree heart block (exception: patients with pacemakers may be enrolled); QRS prolongation or bundle branch block (QRS >= 120 ms), or QT prolongation (per institutional standard of care: QTcF or 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); patients may be potentially eligible once anti-diabetic agent(s) are either added or titrated to control their diabetes mellitus
• Active liver disease (AST or ALT >= 2.0 times the upper limit of normal [ULN] or total bilirubin >= 1.5 times ULN) or gallbladder disease; patients with known liver cirrhosis or severe hepatic impairment (Child-Pugh Class C) will also be excluded
• A known history of human immunodeficiency virus (HIV) seropositivity
• Impairment of gastrointestinal function or gastrointestinal disease that may significantly alter the absorption of ARQ 197 (e.g., uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or significant small bowel resection)
• Patients with an active bleeding diathesis
