Pfizer's New NSCLC ADC Flops in Phase 3, but Combinations Could Revive the Program
Pfizer’s first new ADC after acquiring Seagen failed to meet its primary endpoint in a phase 3 nonsquamous NSCLC trial, showing no significant overall survival advantage vs docetaxel. The company cites a stronger signal in a patient subgroup with one prior therapy and notes ongoing phase 3 studies combining sigvotatug vedotin with pembrolizumab in first-line NSCLC, sustaining optimism for the program despite the setback.
