Summary

This early-stage trial is testing an experimental drug called MK-4716, alone or combined with other cancer drugs, in people with advanced solid tumors that have a KRAS mutation. The main goal is to see if the drug is safe and tolerable. About 250 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
MK-4716 (an experimental drug), pembrolizumab (Keytruda), and cetuximab
What this could lead to
If successful, this could point toward a new treatment option for people with advanced cancers that have a KRAS mutation.
What could go wrong
This is an early Phase 1 trial with only 250 participants, so it is primarily testing safety. The drug may not work or could have side effects.
