Experimental drug tarlatamab targets tough lung cancer
NCT ID NCT03319940
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase study is testing a new drug, tarlatamab, in 269 people with small cell lung cancer that has worsened after standard treatment. Tarlatamab is designed to help the body's immune cells find and attack cancer cells. The main goals are to check the drug's safety, find the right dose, and see how the body processes it.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tarlatamab (a bispecific antibody that helps immune cells attack cancer cells)
- What this could lead to
- If successful, this could lead to a new treatment option for people with small cell lung cancer that has come back after standard therapy.
- What could go wrong
- This is an early Phase 1 trial focused on safety and dosing, so it is too soon to know if tarlatamab will work. Side effects, including cytokine release syndrome, are possible.
