Abstract
Background
Nivolumab plus ipilimumab (NIVO + IPI) demonstrated significant long-term survival and response benefits in patients with previously untreated advanced renal cell carcinoma (aRCC) in the phase III CheckMate 214 trial (NCT02231749). We report final efficacy and safety results with 9.3 years median follow-up.
Patients and methods
Patients (N = 1096) were randomized to NIVO 3 mg/kg plus IPI 1 mg/kg every 3 weeks × four doses, followed by NIVO (3 mg/kg or 240 mg every 2 weeks or 480 mg every 4 weeks); or sunitinib (SUN) (50 mg) once daily (4 weeks on, 2 weeks off). Endpoints: overall survival (OS), and independent radiology review committee-assessed progression-free survival and objective response rate in International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) intermediate/poor-risk (primary), intention-to-treat (secondary), and IMDC favorable-risk (exploratory) patients.
Results
With a median (range) follow-up of 9.3 years (8.6-9.9 years), the hazard ratio (95% confidence interval) for OS with NIVO + IPI versus SUN was 0.71 (0.62-0.82) in intention-to-treat patients, 0.69 (0.59-0.81) in intermediate/poor-risk patients, and 0.80 (0.59-1.09) in favorable-risk patients; 108-month OS probabilities were 31.4% versus 19.5%, 30.2% versus 18.7%, and 35.3% versus 21.8%, respectively. Progression-free survival probabilities at 96 months were 22.7% versus 9.0% (intention-to-treat), 25.4% versus 8.5% (intermediate/poor risk), and 12.5% versus 11.3% (favorable risk). Probabilities of remaining in response at 96 months with NIVO + IPI versus SUN were 48.0% versus 19.0% (intention-to-treat), 50.0% versus 23.0% (intermediate/poor risk), and 36.0% versus not estimable (favorable risk). Incidence of any-grade (grade 3-4) treatment-related adverse events (AEs) was 94.1% (48.6%) with NIVO + IPI versus 97.6% (64.1%) with SUN. Exploratory post hoc analyses reported include descriptive analyses of OS by immune-mediated AE discontinuation status.
Conclusions
In the longest phase III follow-up of a first-line checkpoint inhibitor combination in aRCC (>9 years), NIVO + IPI maintained a substantial survival benefit with durable responses versus SUN. Grade 3-4 treatment-related AEs were lower with NIVO + IPI versus SUN at 9 years. NIVO + IPI remains a first-line standard of care in aRCC.
期刊介绍:
Annals of Oncology, the official journal of the European Society for Medical Oncology and the Japanese Society of Medical Oncology, offers rapid and efficient peer-reviewed publications on innovative cancer treatments and translational research in oncology and precision medicine.
The journal primarily focuses on areas such as systemic anticancer therapy, with a specific emphasis on molecular targeted agents and new immune therapies. We also welcome randomized trials, including negative results, as well as top-level guidelines. Additionally, we encourage submissions in emerging fields that are crucial to personalized medicine, such as molecular pathology, bioinformatics, modern statistics, and biotechnologies. Manuscripts related to radiotherapy, surgery, and pediatrics will be considered if they demonstrate a clear interaction with any of the aforementioned fields or if they present groundbreaking findings.
Our international editorial board comprises renowned experts who are leaders in their respective fields. Through Annals of Oncology, we strive to provide the most effective communication on the dynamic and ever-evolving global oncology landscape.
