AstraZeneca Cision News announced today that its drug combination Imfinzi and Imdelltra has shown a statistically significant and highly clinically meaningful improvement in overall survival and progression-free survival in first-line extensive-stage small cell lung cancer.

The positive top-line results from a planned interim analysis of the DeLLphi-305 Phase III trial reinforce Imfinzi as a backbone immunotherapy for small cell lung cancer across stages of the disease.

This combination marks the first and only immunotherapy, in conjunction with a bispecific T-cell engager, to demonstrate a survival benefit in this specific treatment setting.

The findings support AstraZeneca's ongoing efforts to expand the utility of Imfinzi in treating various forms and stages of lung cancer.
