Voluntary withdrawal of Imfinzi indication in advanced bladder cancer in the US – AstraZeneca

AstraZeneca announced the voluntary withdrawal of the Imfinzi (durvalumab) indication in the US for previously treated adult patients with locally advanced or metastatic bladder cancer. This decision was made in consultation with the FDA.

In May 2017, Imfinzi was granted accelerated approval in the US based on promising tumour response rates and duration of response data from Study 1108, a Phase I/II trial that evaluated the safety and efficacy of Imfinzi in advanced solid tumours, including previously treated bladder cancer. Continued approval was contingent on results from the DANUBE Phase III trial in the 1st-line metastatic bladder cancer setting, which did not meet its primary endpoints in 2020.

The withdrawal is aligned with FDA guidance for evaluating indications with accelerated approvals that did not meet post-marketing requirements, as part of a broader industry-wide evaluation. This withdrawal does not impact the indication outside the US and does not impact other approved Imfinzi indications within or outside the US
