What was measured

The PFS rate was determined in all participants at Month 18. 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 Response Evaluation Criteria in Solid Tumors Version 1.1 (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 date of PD was approximated by the date of the first assessment at which PD was documented per RECIST 1.1 by Blinded Independent Central Review (BICR). Death was always considered as confirmed PD. Participants who did not experience PFS were censored at the last disease assessment. The PFS rate at Month 18 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.
