AstraZeneca, Amgen Drug Moves Closer to Competing With Dupixent in a New Indication
AstraZeneca and Amgen's Tezspire met main and secondary goals in a Phase 3 trial for eosinophilic esophagitis (EoE), according to the companies. They plan to share data with regulators, aiming for approval. Tezspire is already approved for severe asthma and chronic rhinosinusitis with nasal polyps. Analysts project global sales of $2.7B this year, growing to $3.3B by 2027, with EoE approval adding further revenue potential.
