Summary

This trial is testing whether combining an experimental oral drug called IBI351 with the IV drug cetuximab can shrink tumors in people with metastatic colorectal cancer that has a specific KRAS G12C mutation. The study starts with a small group to find the safest dose, then compares the combination against standard chemotherapy in a larger phase. Participants must have the KRAS G12C mutation and measurable tumors, and be in generally good health.

What this could mean

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

Active substance
IBI351 (an experimental oral drug) combined with cetuximab (given by IV)
What this could lead to
If successful, this combination could provide a new targeted treatment option for people with KRAS G12C-mutated metastatic colorectal cancer, potentially improving response rates compared to standard chemotherapy.
What could go wrong
This is an early-phase trial with a small number of participants, so results may not hold up in larger studies. The combination may cause side effects, and not all patients may benefit.
