A Phase 1 Study of ARQ 197 in Adult Patients With Advanced Solid Tumors (ARQ 197)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This is an open label, single arm, dose escalation study of ARQ 197 in patients with advanced solid tumors.
Condition or disease
Cancer, Advanced Solid Tumors
Drug: ARQ 197
Patients will take ARQ 197 orally twice daily continuously at dose levels specified for their respective dose cohorts. The ARQ 197 starting dose will be a total daily dose of 200 mg (100 mg bid). ARQ 197 treatment will be continued until progression of disease, unacceptable toxicity, or another discontinuation criterion is met. In the case of toxicity, dose adjustment is permitted. A treatment cycle is designed as four weeks (28 days) and will be repeated without therapy interruption.
Safety, tolerability [ Time Frame: ARQ 197 treatment will be continued until progression of disease, unacceptable toxicity, or another discontinuation criterion is met ]
Secondary Outcome Measures
To evaluate pharmacodynamics of phosphorylated c-Met, total c-Met, apoptosis marker (TUNEL) and phosphorylated FAK in tumor tissue correlated with administration of ARQ 197. [ Time Frame: ARQ 197 treatment will be continued until progression of disease, unacceptable toxicity, or another discontinuation criterion is met ]
To assess the preliminary anti-tumor activity of ARQ 197. [ Time Frame: ARQ 197 treatment will be continued until progression of disease, unacceptable toxicity, or another discontinuation criterion is met ]
To determine the pharmacokinetic (PK) profile of ARQ 197 with continuously twice daily oral dosing schedule. [ Time Frame: ARQ 197 treatment will be continued until progression of disease, unacceptable toxicity, or another discontinuation criterion is met ]

Karnofsky performance status (KPS) ≥ 70% or Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1
Male or female patients of child-producing potential must agree to use contraception or avoidance of pregnancy measures during the study and for 30 days after the last ARQ 197 dose
Females of childbearing potential must have a negative serum pregnancy test

Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, clinically significant non-healing or healing wounds, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, significant pulmonary disease (shortness of breath at rest or mild exertion), uncontrolled infection or psychiatric illness/social situations that would limit compliance with study requirements
