Summary

This early-phase trial is testing a new drug called AMG 436, alone or with other cancer treatments, in adults with advanced solid tumors that have high microsatellite instability or mismatch repair deficiency. The main goals are to check safety, find the best dose, and see how the drug moves through the body. About 464 participants will be enrolled.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
AMG 436
What this could lead to
If successful, this could lead to a new treatment option for people with hard-to-treat cancers that have specific genetic features.
What could go wrong
This is an early phase 1 trial focused on safety and dosing, so it is unknown if AMG 436 will effectively shrink tumors or improve survival. Side effects are possible.
