This approval is based on results from the Phase 3 KEYNOTE-564 trial, in which KEYTRUDA demonstrated a statistically significant improvement in disease-free survival (DFS), reducing the risk of disease recurrence or death by 32% (HR=0.68 [95% CI, 0.53-0.87]; p=0.0010) after a median follow-up of 23.9 months compared to placebo, in patients at increased risk of recurrence.

The approval was based on data from KEYNOTE-564 (NCT03142334), a multicenter, randomized, double-blind, placebo-controlled Phase 3 trial that enrolled 994 patients with increased risk of recurrence of RCC defined as intermediate-high or high risk, or M1 with no evidence of disease (NED). Patients must have undergone a partial or radical complete nephrectomy (and complete resection of solid, isolated, soft tissue metastatic lesion[s] in M1 NED participants) with negative surgical margins for at least four weeks prior to the time of screening. Patients with active autoimmune disease or a medical condition that required immunosuppression were excluded from the study. The primary efficacy outcome measure was investigator-assessed DFS. The secondary efficacy outcome measure was overall survival (OS). Patients with RCC with clear cell component were randomized (1:1) to receive KEYTRUDA 200 mg administered intravenously every three weeks (n=496) or placebo (n=498) for up to one year until disease recurrence or unacceptable toxicity.
At a pre-specified interim analysis with a median follow-up time of 23.9 months, KEYTRUDA demonstrated a statistically significant improvement in DFS, reducing the risk of disease recurrence or death by 32% (HR=0.68 [95% CI, 0.53-0.87]; p=0.0010) compared with placebo in patients with RCC at increased risk of recurrence following nephrectomy, or following nephrectomy and resection of metastatic lesions. Updated efficacy results with a median follow-up time of 29.7 months demonstrated KEYTRUDA reduced the risk of disease recurrence or death by 37% (HR=0.63 [95% CI, 0.50-0.80]; p
