A retrospective chart review of UK patients with advanced renal cell carcinoma treated with nivolumab plus ipilimumab

There is limited real-world evidence regarding patients with intermediate/poor-risk advanced renal cell carcinoma (aRCC) receiving nivolumab plus ipilimumab (NIVO+IPI) in England. This study aimed to describe characteristics, treatment patterns, and efficacy outcomes in these patients. A retrospective chart review of medical records in patients with aRCC receiving NIVO+IPI at any line of therapy between 5 April 2019 and 1 April 2022 in five sites across England was conducted. Data were analyzed descriptively overall, in patients with and without NIVO maintenance after NIVO+IPI initiation, and by prior nephrectomy status. In total, 128 patients (mean age 60.7 years [standard deviation 10.1], 71.1% male) were eligible; most received first-line (1L) NIVO+IPI (n = 122, 95.3%). Median follow-up was 13.6 months (interquartile range [IQR] 7.1–25.0). Median progression-free survival and overall survival (OS) were 7.6 months (95% confidence interval [CI]: 5.6, 13.1) and 30.7 months (95% CI: 22.5, not reached), respectively. Median OS was not reached in patients who received NIVO+IPI plus NIVO maintenance and patients with prior nephrectomy. Patients who received NIVO+IPI with NIVO maintenance and patients who had undergone prior nephrectomy experienced the most favorable survival outcomes, aligning with results from previous studies.
