Amgen receives EU marketing authorisation for IMDYLLTRA in ES-SCLC
2 June 2026 -

US biopharmaceutical company Amgen (NASDAQ:AMGN) announced on Monday that it has received marketing authorisation from the European Commission for IMDYLLTRA (tarlatamab) as a monotherapy to treat adults with extensive-stage small cell lung cancer (ES-SCLC) who require systemic therapy following disease progression on or after first-line treatment with platinum-based chemotherapy.

This approval was based on results from DeLLphi-304, the first global Phase 3 trial to demonstrate a significant survival benefit over chemotherapy in this setting.

In the trial, IMDYLLTRA reduced the risk of death by 40% and significantly extended median overall survival (OS) by more than five months compared to standard of care (SOC) chemotherapy as a treatment for patients with ES-SCLC who progressed on or after one line of platinum-based chemotherapy.
