A phase III trial of PD-1 inhibitor Opdivo showed significant survival benefit at one year—compared to investigator’s choice of methotrexate, docetaxel or cetuximab—in patients with recurrent or metastatic squamous cell carcinoma of the head and neck.
Patients treated with Opdivo (nivolumab) experienced a 30 percent reduction in the risk of death, with a median overall survival of 7.5 months (95% CI: 5.5-9.1) compared to 5.1 months (95% CI: 4.0-6.0) for investigator’s choice (HR=0.70 [97.73% CI: 0.51-0.96] p=0.0101).
The one-year survival rate for Opdivo was 36 percent compared to 16.6 percent for investigator’s choice. The safety profile of Opdivo in CheckMate-141 was consistent with prior studies, with no new safety signals identified.
