New combo therapy shows promise for tough lung cancer
NCT ID NCT04885998
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study tested a combination of two drugs, tarlatamab and AMG 404, in 23 adults with small cell lung cancer that had worsened after standard chemotherapy. The main goal was to check safety and find the right dose for future studies. Participants had to be in fairly good health (ECOG 0-1) and could have treated brain metastases.
