Toripalimab Emerges as Preferred PD-1 Inhibitor for Metastatic Nasopharyngeal Carcinoma Despite Access Challenges
- Toripalimab has received NCCN category 1 recommendation for nasopharyngeal carcinoma based on positive phase 3 data in both first-line and second-line settings, unlike pembrolizumab which showed negative results in the KEYNOTE-122 trial.
- Clinical practitioners report easier insurance coverage for pembrolizumab compared to toripalimab, leading many to use pembrolizumab off-label in combination with chemotherapy despite inferior clinical evidence.
- PD-1 inhibitors combined with chemotherapy represent the established standard of care for systemic recurrent nasopharyngeal carcinoma, with EBV levels serving as useful biomarkers for monitoring treatment efficacy.
- Future treatment approaches may focus on novel combinations including CAR-T cell therapy, tumor-infiltrating lymphocytes, and targeted therapies like EGFR inhibitors to improve outcomes while reducing toxicity.
