Clinical question
Does adjuvant nivolumab plus ipilimumab improve disease-free survival after nephrectomy for high-risk RCC?
Trial context
Population
816 patients with localized RCC at high risk of recurrence after nephrectomy
Intervention
Adjuvant nivolumab + ipilimumab vs placebo after nephrectomy
Key endpoint
24-month disease-free survival
Time horizon / follow-up
24 months
Absolute Effect
What changes for patients?
At 24 months, disease-free survival was 76% with nivolumab plus ipilimumab versus 74% with placebo, an absolute difference of only 2 percentage points (NNT 50). The primary DFS endpoint was not met. Grade 3–5 adverse events were 38% vs 10%, and treatment discontinuation was 32% vs 2%.
NNT: 50
Treatment burden / harm
Grade 3–5 adverse events
NNH: 4
Relative effect
HR: 0.92
95% CI 0.71–1.19; P=.53
Clinical interpretation
The negative primary endpoint and added immune toxicity argue against adjuvant nivolumab plus ipilimumab after nephrectomy as a routine RCC strategy.
Current-practice context · reviewed 14 October 2026
Adjuvant nivolumab plus ipilimumab did not improve the primary disease-free-survival endpoint in resected high-risk RCC and added immune toxicity. The combination should not be considered an adjuvant standard; current postoperative discussion should instead use the evidence and eligibility criteria for adjuvant pembrolizumab, surveillance and current RCC guidance.
