Pfizer’s first new ADC from Seagen acquisition fails phase 3 NSCLC trial
📍 The outcome
{ "epilogue": "Pfizer reported mixed phase 3 data after its experimental drug, sigvotatug vedotin, missed the main goal of a lung cancer trial. The Seagen-origin antibody-drug conjugate failed to significantly improve overall survival in advanced, pretreated nonsquamous non-small cell lung cancer.
Consequently, the latest oncology hurdle added to ongoing scrutiny regarding the $43 billion Seagen acquisition." }
