AstraZeneca announces positive results for the Phase III PACIFIC trial.

The trial is a randomised, double-blinded, placebo-controlled multi-centre trial of Imfinzi as sequential treatment in patients with locally-advanced, unresectable non-small cell lung cancer who had not progressed following standard platinum-based chemotherapy concurrent with radiation therapy.

A planned interim analysis conducted by an Independent Data Monitoring Committee (IDMC) concluded that the trial has already met a primary endpoint by showing statistically-significant and clinically-meaningful PFS, as assessed by blinded independent central review, in patients receiving Imfinzi compared to placebo. The results also demonstrate a favourable benefit/risk profile. The trial will also evaluate overall survival (OS), the other primary endpoint, which will be assessed in due course as specified by the protocol. AstraZeneca plans to submit the initial results from the PACIFIC trial for presentation at a forthcoming medical meeting.

“These are highly encouraging results for patients with locally-advanced lung cancer for whom surgery is not an option. We look forward to working with regulatory authorities around the world to bring Imfinzi to lung cancer patients as soon as possible. Alongside this, we continue to explore Imfinzi’s full potential as monotherapy as well as in combination with tremelimumab and other medicines in areas of continued unmet need across multiple types of cancer,” says Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca.
