Oncology Approved 2024-05-16

IMDELLTRA (tarlatamab-dlle) is a bispecific T-cell engager indicated for the treatment of adult patients with extensive stage small cell lung cancer (ES-SCLC). This therapy is specifically designated for patients who have experienced disease progression on or after receiving platinum-based chemotherapy. It functions as a targeted treatment option for individuals with advanced SCLC who require subsequent lines of therapy.

How IMDELLTRA Works

Tarlatamab-dlle is a bispecific molecule that binds to DLL3 expressed on tumor cells and CD3 expressed on T cells. By bridging these two cells, the drug triggers T-cell activation and the release of inflammatory cytokines. This interaction results in the lysis of DLL3-expressing cells, demonstrating anti-tumor activity in small cell lung cancer models.
