About COMETRIQ COMETRIQ’s safety and efficacy was assessed in an international, multi-center, randomized double-blinded controlled trial called EXAM of 330 patients with progressive, metastatic medullary thyroid carcinoma (MTC). Patients were required to have evidence of actively progressive disease within 14 months prior to study entry confirmed by an Independent Radiology Review Committee (IRRC) masked to treatment assignment (89%) or the treating physician (11%). Patients were randomized (2:1) to receive COMETRIQ 140 mg (n = 219) or placebo (n = 111) orally, once daily until disease progression determined by the treating physician or until intolerable toxicity. Randomization was stratified by age (≤65 years vs. > 65 years) and prior use of a tyrosine kinase inhibitor (TKI). No cross-over was allowed at the time of progression. The main efficacy outcome measures of PFS, objective response and response duration were based on IRRC-confirmed events using the modified RECIST criteria. A statistically significant prolongation in PFS was demonstrated among COMETRIQ-treated patients compared to those receiving placebo [HR 0.28 (95% CI: 0.19, 0.40); p<0.0001], with median PFS times of 11.2 months and 4.0 months in the COMETRIQ and placebo arms, respectively. Partial responses were observed only among patients in the COMETRIQ arm (27% vs 0; p<0.0001). The median duration of objective responses was 14.7 months (95% CI: 11.1, 19.3) for patients treated with COMETRIQ. There was no statistically significant difference in overall survival between the treatment arms at the planned interim analysis.
COMETRIQ Mechanism of ActionCOMETRIQ (cabozantinib) inhibits the activity of tyrosine kinases including RET, MET and VEGFR2. These receptor tyrosine kinases are involved in both normal cellular function and in pathologic processes such as oncogenesis, metastasis, tumor angiogenesis, and maintenance of the tumor microenvironment.
