Amgen AMGN announced that the European Commission (“EC”) has approved Imdylltra (tarlatamab) to treat adults with extensive-stage small cell lung cancer (“SCLC”) who require systemic therapy following disease progression on or after first-line platinum-based chemotherapy.
The EC decision is based on results from the phase III DeLLphi-304 study, which showed that treatment with the drug reduced the risk of death by 40% and also significantly extended the median overall survival by more than five months compared with standard of care.
The drug is already approved for a similar indication in the United States, where it is marketed under the brand name Imdelltra. While the drug was initially approved in May 2024 under the accelerated pathway, it secured full approval last year, also supported by data from the DeLLphi-304 study.

More on Amgen’s Imdelltra/Imdylltra
Imdelltra, or Imdylltra, is a bispecific T-cell engager therapy designed to target and destroy DLL3-expressing SCLC cells. Since its commercial launch, the drug has emerged as a key growth driver for Amgen. In the first quarter of 2026, Imdelltra generated sales of $258 million, up 219% year over year and 10% sequentially, driven primarily by volume growth.
The newly secured EU approval is expected to meaningfully expand Imdelltra's commercial opportunity by opening access to additional patients across Europe. Reflecting this growth potential, the Zacks Consensus Estimate projects 2026 sales of the drug at about $1.2 billion, nearly double of $627 million generated in 2025, highlighting the drug's blockbuster potential.
Several phase III studies are currently evaluating Imdelltrain earlier-line settings across both extensive-stage and limited-stage SCLC. Given the limited treatment options available for patients with SCLC, successful expansion into earlier treatment settings could further increase the drug's addressable market and support long-term sales growth.
