Summary

This study tests an experimental drug called KL590586, taken as a capsule, in people with advanced solid tumors that have specific RET gene changes. The trial has two phases: Phase I checks safety and the right dose, while Phase II looks at how well the drug shrinks tumors. Up to 414 participants with cancers like lung or thyroid that have not responded to standard treatments will be enrolled.

What this could lead to

If successful, this could provide a new targeted treatment option for people with advanced solid tumors that have specific RET gene changes.
