Keytruda plus Lenvima reduced the risk of disease progression or death by 53%, with a median progression-free survival (PFS) of 23.9 months versus 9.2 months for sunitinib.
The objective response rate (ORR) was 71.3%, with a complete response (CR) rate of 18.3% for Keytruda plus Lenvima versus an ORR of 36.7% with a CR rate of 4.8% for sunitinib.
There were no new safety signals, and the safety profile at the final OS analysis was consistent with the primary analysis.
