There will be three parts to this phase I study: 1) the Combination Dose Finding cohort; 2) the Combination Expansion cohort; and 3) the Monotherapy MET Amplified cohort. In the Combination Dose Finding cohort and the Combination Expansion cohort, we will combine cabozantinib and panitumumab in patients with KRAS wild-type metastatic colorectal cancer (CRC). In the Monotherapy MET Amplified cohort, we will screen at least 50 patients for MET gene amplification ("MET amplification"). Patients with MET amplification will receive cabozantinib only (monotherapy).
