Nivolumab and ipilimumab combination therapy for melanoma efficacy, safety and clinical integration in metastatic and adjuvant settings
摘要
Melanoma remains one of the most aggressive cutaneous malignancies, accounting for a disproportionate share of skin cancer-related mortality despite relatively lower incidence. Over the past decade, immune checkpoint inhibitors (ICIs) have revolutionized melanoma management, with dual blockade of programmed death receptor-1 (PD-1) and cytotoxic T-lymphocyte–associated protein-4 (CTLA-4) representing one of the most impactful therapeutic advances. This narrative review critically examines the clinical integration of nivolumab–ipilimumab (Nivo-Ipi) combination therapy across metastatic, neoadjuvant, and adjuvant melanoma settings, with emphasis on efficacy, safety, and emerging clinical challenges. Evidence from pivotal randomized trials, particularly the 10-year final outcomes of CheckMate 067, demonstrates that Nivo-Ipi confers substantial improvements in overall survival compared with ipilimumab monotherapy, and numerically superior outcomes compared with nivolumab monotherapy—though the trial was not powered to formally establish this latter comparison. Landmark analyses reveal durable survival plateaus extending beyond seven years in approximately 31% of combination-treated patients, redefining expectations for advanced melanoma. However, this enhanced efficacy is accompanied by significantly higher rates of immune-related adverse events (irAEs), necessitating careful patient selection and proactive toxicity management. Emerging data from the NADINA trial establish a compelling neoadjuvant role for the combination, while the adjuvant CheckMate 915 trial failed to demonstrate recurrence-free survival benefit over nivolumab monotherapy. Future progress will depend on biomarker-driven personalization, refined sequencing strategies, and integration of the combination within an increasingly competitive first-line landscape that now includes nivolumab plus relatlimab.
