Objectives
Immune checkpoint inhibitor (ICI) therapy has demonstrated substantial benefits for certain patients. We try to evaluate the merits and demerits of each immunotherapy to aid clinical treatment.
Methods
We conducted a comprehensive search of the PubMed, Embase, and Cochrane databases for randomized clinical trials published as of June 10, 2023. Our study included published clinical trials of ICI monotherapy or combination therapy, along with data on treatment‐related adverse events (TRAE). Data regarding survival efficacy and adverse events of each randomized controlled trial (RCT) were collected. The Bayesian random effects model was utilized for the network meta‐analysis (NMA).
Results
This study incorporated 19 RCTs, involving 5900 patients. Among 14 treatment regimens, Pembrolizumab combined with chemotherapy emerged as the most promising primary treatment for overall survival (OS) and objective response rate (ORR). Toripalimab combined with chemotherapy exhibited the highest likelihood of becoming the primary treatment for extending progression‐free survival (PFS). Durvalumab showed the lowest probability of adverse events, suggesting a safer profile compared with other drugs. Camrelizumab combined with chemotherapy demonstrated a heightened risk of adverse events. Dual ICI Nivolumab/Ipilimumab surpassed Durvalumab/Tremelimumab in terms of ORR and adverse events. The standard of care (SOC) regimen did not exhibit strong performance across the four outcome indicators.
Conclusion
Our analysis suggests that the integration of chemotherapy agents with ICIs enhances its efficacy as a first‐line treatment for patients with advanced head and neck cancer (HNC).
