What was measured

PFS was defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurred first. Per RECIST 1.1, PD was defined as ≥20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions was also considered PD. The PFS per RECIST 1.1 was calculated using the product-limit (Kaplan-Meier) method for censored data. The PFS for participants is presented.

Analysis population: The analysis population consisted of all randomized participants.

Groups in this outcome

Pembrolizumab + Axitinib

Participants received pembrolizumab 200 mg intravenously every 3 weeks PLUS axitinib 5 mg orally twice daily.

Sunitinib

Participants received sunitinib 50 mg orally once daily for 4 weeks and then were off treatment for 2 weeks.
