Longer survival than chemotherapy in a randomized trial.

TreatmentWith your doctor

What studies found

In DeLLphi-304 (509 patients), tarlatamab gave median survival of 13.6 months versus 8.3 months with standard chemotherapy. The FDA gave full approval on 19 November 2025.

The catch

It carries a boxed warning for life-threatening cytokine release syndrome and nerve toxicity.

What to do

If small cell lung cancer comes back after chemotherapy, ask whether tarlatamab is an option.
