KEYNOTE-426
The first immunotherapy plus targeted-pill combination for kidney cancer, improving survival across all risk groups.
OS HR 0.53 at first analysis; final (5-year) OS HR 0.84 with medians 47.2 vs 40.8 months; PFS 15.7 vs 11.1. FDA approval April 2019. Benefit attenuated over time as crossover to later-line immunotherapy accrued in the control arm.
- Median 47.2 vs 40.8 months with Pembrolizumab + axitinib compared with Sunitinib; about 6.4 months longer for half the group.
- A median is a midpoint: half the people did better than this and half did worse, so it is not a prediction for any one person.
- Put another way, the treated group had about 16 percent lower chance of the event at any given time (hazard ratio 0.84, likely range 0.71 to 0.99).
- Overall survival counts deaths from any cause, so it is the most direct measure of whether a treatment helps people live longer.
- Median 15.7 vs 11.1 months with Pembrolizumab + axitinib compared with Sunitinib; about 4.6 months longer for half the group.
- A median is a midpoint: half the people did better than this and half did worse, so it is not a prediction for any one person.
- Put another way, the treated group had about 31 percent lower chance of the event at any given time (hazard ratio 0.69).
- This is a surrogate endpoint: it measures the cancer being controlled or absent on scans and tests, which often, but not always, translates into living longer.
- These results apply to the people the trial enrolled: Untreated advanced clear-cell RCC: pembrolizumab + axitinib vs sunitinib. People in a different situation may not see the same effect.
