Trial of ARQ 197 in Patients With Unresectable Hepatocellular Carcinoma (HCC) Who Have Failed One Prior Systemic Therapy

Study Overview
=================
Brief Summary
-----------------
This is a global randomized, placebo-controlled, double-blinded Phase 2 study designed to compare treatment of ARQ 197 versus placebo in patients with unresectable HCC who had radiographic disease progression after systemic first line therapy or were unable to tolerate the therapy.

Detailed Description
-----------------
Patients will be randomly assigned in a 2:1 ratio to receive ARQ 197 or placebo. The treatment assignment will be stratified based on Eastern Cooperative Oncology Group (ECOG) performance status (PS), and vascular invasion status. The treatment with ARQ 197 or placebo will be continued until progression of disease, unacceptable toxicity, or another discontinuation criterion listed in this protocol is met. After radiographic disease progression is documented, treatment assignment will be unblinded. Patients who were assigned to placebo arm and had documented radiographic disease progression will have the option to receive ARQ 197 and will be evaluated for objective response rate and disease control rate continuously. The study will continue until 78 total time to progression events are reached. At the end of study, all remaining patients still on treatment will have the option to be rolled over to another study to continue their treatment.

Eligibility Criteria
-----------------
Inclusion Criteria: Written informed consent granted prior to initiation of any study-specific screening procedures 18 year of age or older Histologically or cytologically confirmed HCC Archival, fresh core needle biopsy or fine needle aspiration (FNA) tumor samples Received at least one cycle of prior systemic therapy (at least 3 weeks for continuously administered drugs) and experienced radiographic disease progression or was unable to tolerate therapy. If intolerance was manifested by a Grade 3 or 4 event of such nature that re-challenge is not acceptable, less than 3 weeks of continuous administration will be allowed Discontinued prior treatment for at least 4 weeks, or at least 2 weeks (14 days) if drug was administered continuously and orally (e.g. sorafenib or sunitinib), prior to the study randomization Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) ≤1 Local or loco-regional therapy (i.e., surgery, radiation therapy, hepatic arterial embolization, chemoembolization, radiofrequency ablation, percutaneous ethanol injection, or cryoablation) must have been completed ≥4 weeks prior to randomization Measurable disease as defined by a modified version of the revised Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (see section 9). Tumor lesions previously treated with local therapy should demonstrate clear dimensional increase by radiographic assessment in order to be selected as target lesion(s) at baseline. (Radiological assessment needs to be redone within 7 days prior to randomization if the pre-study AFP level has increased by more than 30% since the last AFP level taken one to four months prior to randomization) Adequate bone marrow, liver, and renal functions at Pre-Study Visit, defined as: Platelet count ≥ 60 × 10^9/L Hemoglobin ≥ 9.0 g/dL Absolute neutrophil count (ANC) ≥1.5 × 10^9/L Total bilirubin ≤ 2 mg/dL Alanine transaminase (ALT) and aspartate transaminase (AST) ≤ 5 × upper limit of normal (ULN) Serum creatinine ≤1.5 × ULN International normalized ratio (INR) 0.8 to 1.4 or ≤3 for patients receiving anticoagulant such as coumadin or heparin. Patients who are therapeutically anticoagulated are allowed to participate provided that no prior evidence of underlying abnormality exists in these parameters Albumin ≥ 2.8 g/dL Women of childbearing potential must have a negative pregnancy test performed within ten days prior to the start of study drug Male and female subjects of child-bearing potential must agree to use double-barrier contraceptive measures, oral contraception, or avoidance of intercourse during the study and for 90 days after last investigational drug dose received Exclusion Criteria: More than 1 prior systemic regimen Child-Pugh B-C cirrhotic status Previous or concurrent cancer that is distinct from HCC in primary site or histology, EXCEPT cervical carcinoma in situ, treated basal cell carcinoma, superficial bladder tumors (Ta, Tis & T1). Any cancer curatively treated >3 years prior to enrollment is permitted History of congestive heart failure defined as Class II to IV per New York Heart Association (NYHA) classification within 6 months prior to study entry; active coronary artery disease (CAD); clinically significant bradycardia or other uncontrolled, cardiac arrhythmia defined as ≥Grade 3 according to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4.0, or uncontrolled hypertension; myocardial infarction occurring within 6 months prior to study entry (myocardial infarction occurring >6 months prior to study entry is permitted) Active clinically serious infections defined as ≥ Grade 3 according to NCI CTCAE, version 4.0. Substance abuse, medical, psychological or social conditions that may, in the opinion of the Investigator, interfere with the patient's participation in the study or evaluation of the study results Any condition that is unstable or which could jeopardize the safety of the patient and his/her protocol compliance Known human immunodeficiency virus (HIV) infection Pregnancy or breast-feeding History of liver transplant Inability to swallow oral medications Clinically significant gastrointestinal bleeding occurring ≤4 weeks prior to randomization

| Experimental: ARQ 197<br> | Drug: ARQ 197<br>* The investigational drug ARQ 197 is supplied as capsules. A dose of 360 mg (3 capsules of 120 mg each) of ARQ 197 will be administered by mouth BID, once in the morning and once in the evening with meals, for a total daily dose of 720 mg. Under Amendment 2, a dose of 240 mg (2 capsules of 120 mg each) of ARQ 197/placebo will be administered by mouth BID, once in the morning and once in the evening with meals, for a total daily dose of 480 mg. A treatment cycle is defined as 4 weeks for both treatment arms. Cycles will be repeated every 4 weeks (28 days) based on toxicity and response.<br>* Other names: Tivantinib;|
