Efficacy and safety of nivolumab plus ipilimumab in patients with metastatic variant histology (non-clear cell) renal cell carcinoma.
Article in Journal for immunotherapy of cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNivolumab plus ipilimumab (nivo/ipi) is a standard of care first-line (1 L) therapy for patients with metastatic clear-cell renal cell carcinoma (ccRCC), but its role in patients with metastatic, non-ccRCC has not been fully defined. We report a single-institution experience with nivo/ipi in non-ccRCC.
methodsBetween November 2017 and February 2024, 55 patients with metastatic non-ccRCC received nivo/ipi at MD Anderson Cancer Center. The tumor response was assessed by blinded radiologists using RECIST v1.1. The overall response rate (ORR), progression-free survival (PFS), PFS milestone, duration of response (DoR), and overall survival (OS) were determined. Next-generation sequencing (NGS) was performed on available tumor specimens.
resultsTwenty-five (45.5%) patients had papillary histology (pRCC), 12 (21.8%) patients had chromophobe (chRCC), and 18 (32.7%) patients had unclassified RCC (uRCC). Fifty-two (94.5%) patients received nivo/ipi in 1 L. Sarcomatoid features (SF) were found in 20 (36.4%) cases. ORR was 48% (12/25) in pRCC, 25% (3/12) in chRCC (all 3 cases had SF), 27.8% (5/18) in uRCC, and 55% (11/20) across histologies with SF.The median PFS was 10.6 months (95% CI: 2.8 to 22.8) in pRCC, 3.6 months (95% CI: 0.9 - NE) in chRCC, and 3 months (95% CI: 2.1 to 7) in uRCC; 6-month milestone PFS was 56% (95% CI: 36.3 to 75.7), 41.7% (95% CI: 22 to 61.3), and 38.9% (95% CI: 21.7 to 56.1) in pRCC, chRCC, and uRCC, respectively. The median DoR for the entire cohort was 8.5 months (95% CI: 8 - NE). The median OS was 36.7 months (95% CI: 11.5 to 54.8) in pRCC, 25.7 months (95% CI: 0.9 - NE) in chRCC, and 11.1 months (95% CI: 6.5 - NE) in uRCC.Ten (18.2%) patients discontinued treatment due to treatment-related adverse events (AEs). Grade 3/4 immune-mediated AEs were noted in 17 (30.9%) patients. We performed NGS on 26 cases:
conclusionNivo/ipi produced favorable outcomes in patients with pRCC supporting its use as 1 L therapy. Responses in patients with chRCC were noted exclusively with SF. Despite achieving an ORR of 27.8% with nivo/ipi, patients with uRCC had short PFS and inferior OS.
