What was measured

ORR is defined as best overall response (BOR) of a complete response (CR) or partial response (PR) divided by the number of randomized participants for each treatment group. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes(whether target or non-target) must have reduction in short axis to \< 10 mm. Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

Groups in this outcome

Treatment A - Platinum Refractory Subgroup

Participants with histologically confirmed Squamous Cell Carcinoma of the Head and Neck (SCCHN) that has recurred during or less than 6 months after completion of previous platinum-based chemotherapy. Treated with Nivolumab 3 mg/kg Q2W + Ipilimumab 1 mg/kg Q6W

Treatment B - Platinum Refractory Subgroup

Participants with histologically confirmed Squamous Cell Carcinoma of the Head and Neck (SCCHN) that has recurred during or less than 6 months after completion of previous platinum-based chemotherapy. Treated with Nivolumab 3 mg/kg Q2W + Ipilimumab-Placebo Q6W
