IO Biotech Inc. announced five-year clinical outcomes from the Phase 1/2 MM1636 trial in Nature Communications. The study evaluated the IO102-IO103 vaccine in combination with PD-1 blockade for metastatic melanoma. Results showed a median progression-free survival of 25.5 months, a median duration of response over 53 months, and a median overall survival of 60 months. These findings supported the FDA Breakthrough Therapy Designation for IO102-IO103 with pembrolizumab and the ongoing Phase 3 IOB-013/KN-D18 trial.
