Five years after surgery, a personalized cancer vaccine may still be protecting melanoma patients from recurrence.
New five-year data from the KEYNOTE-942 trial — led by Dr. Janice Mehnert of NYU Langone's Perlmutter Cancer Center — suggest that combining intismeran, an individualized mRNA neoantigen vaccine, with standard pembrolizumab therapy may offer durable protection in patients with resected high-risk melanoma.
At 60 months, recurrence-free survival was 68.8% in the combination arm versus 49.1% with pembrolizumab alone — a 49% reduction in recurrence or death risk. Distant metastasis-free survival risk was reduced by 59%.
Each vaccine was built from the patient's own tumor — encoded with up to 34 patient-specific neoantigens — designed to train T cells to recognize and attack returning cancer cells.
A phase 3 trial is fully enrolled. Results are anticipated soon.
