What was measured

Complete Response (CR): The disappearance of all measurable lesions. Partial Response (PR): At least a 30% decrease in the sum of the longest diameters of measureable lesions, taking as reference the baseline sum longest diameter. Progressive Disease (PD): At least a 20% increase in the sum of the longest diameters of target lesions, taking as reference the smallest sum longest diameter recorded since the baseline measurements, or the appearance of one or more new lesion(s). Stable Disease (SD): Neither sufficient shrinkage to qualify for partial response nor sufficient increase to qualify for progressive disease. To be assigned a status of stable disease, measurements must have met the stable disease criteria at least once after study entry at a minimum interval of 6 weeks.

Analysis population: Participants evaluable for response

Groups in this outcome

Phase I Lead in + Phase II: Cohort A

Patients who had progressed on at least one prior line of treatment for their recurrent and/or metastatic HNSCC Participants were treated with Nivolumab and Cetuximab at recommended Phase II dose (RP2D). Nivolumab: Nivolumab intravenously (IV) at 240 mg as outlined in the treatment arms. Cetuximab: Cetuximab intravenously (IV) at 500 mg/m\^2 or 250 mg/m\^2 as outlined in the treatment arms.

Phase II - Cohort B

Patients who have not had any prior treatment for their recurrent and/or metastatic HNSCC Participants were treated with Nivolumab and Cetuximab at recommended Phase II dose (RP2D). Nivolumab: Nivolumab intravenously (IV) at 240 mg as outlined in the treatment arms. Cetuximab: Cetuximab intravenously (IV) at 500 mg/m\^2 or 250 mg/m\^2 as outlined in the treatment arms.
