Why it may matterVerify against the original reporting
Substantial Phase 2 efficacy signals (OS, ORR, CR) in 1L HNSCC and an ongoing Phase 3 with topline data due later this year create a near-term upside risk/reward for GMAB if Phase 3 confirms or improves results; potential re-rating on data clarity and HPV-agnostic activity.
