About
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.
Full 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.

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:
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
