Trial Summary

What is the purpose of this trial?

This trial is testing a new oral medication called KRT-232 for patients with small cell lung cancer that has returned or resisted other treatments. The medication works by blocking a protein that helps cancer cells grow. The study will test different doses to find the most effective one. Niclosamide, originally a drug for treating parasitic infections, has shown potential in fighting small cell lung cancer.
