Exelixis Renal Cell Carcinoma Study Misses Endpoint
Exelixis says its Phase 3 CONTACT-03 study evaluating the company’s Cabometyx (cabozantinib) in combination with atezolizumab (Roche’s Tecentriq) versus cabozantinib alone in certain patients with renal cell carcinoma (RCC) did not meet its primary endpoint of progression-free survival (PFS). The study assessed patients who progressed during or after immune checkpoint inhibitor therapy (either combination or monotherapy). “The safety profile of the combination of cabozantinib and atezolizumab observed in the trial was consistent with the known safety profiles for each single agent, and no new safety signals were identified with the combination,” the company says.
The primary endpoints of the trial are PFS per response evaluation criteria in solid tumors as assessed by independent radiology review and overall survival, the company says. Key secondary endpoints include PFS, objective response rate and duration of response as assessed by the investigators. The study is sponsored by Roche and co-funded by Exelixis. More information about CONTACT-03 is available at ClinicalTrials.gov.
Cabometyx tablets are currently approved for treating patients with advanced RCC, patients with hepatocellular carcinoma who have been previously treated with sorafenib, patients with advanced RCC as a first-line treatment in combination with nivolumab and certain adult and pediatric patients 12 years of age and older with locally advanced or metastatic differentiated thyroid cancer.
