Bristol-Myers Squibb Company announced that its Opdivo (nivolumab) 3 mg/kg plus low-dose Yervoy (ipilimumab) 1 mg/kg (injections for intravenous use) has received approval from the US Food and Drug Administration for the treatment of adult and pediatric patients 12 years and older with microsatellite instability high (MSI-H) or mismatch repair deficient (dMMR) metastatic colorectal cancer (mCRC) that has progressed following treatment with a fluoropyrimidine, oxaliplatin and irinotecan. Approval for this indication has been granted under accelerated approval based on overall response rate (ORR) and duration of response (DOR). Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory clinical trials.
Clinical Basis of Approval:
Approval of new indication was based on data from the ongoing phase 2 CheckMate -142 study evaluating the Opdivo + Yervoy combination in patients with MSI-H or dMMR mCRC previously treated with a fluoropyrimidine-, oxaliplatin- or irinotecan-based chemotherapy.1,3,4 The application was granted Priority Review and Breakthrough Therapy Designation by the US FDA.
The Opdivo + Yervoy cohort of the CheckMate -142 trial enrolled MSI-H/dMMR mCRC patients who had received at least one prior line of therapy for metastatic disease, and efficacy was analyzed for both patients who had received prior treatment with a fluoropyrimidine, oxaliplatin and irinotecan (82 of the total 119 patients) as well as for all enrolled patients.
