Summary

This early-phase trial tested a drug called SHR-A1811 in 396 people with advanced solid tumors that have HER2 expression or mutations and have stopped responding to standard treatments. The main goals were to check safety and how the drug moves through the body, while also looking for signs of tumor shrinkage. The drug is given by IV infusion, and the study is now complete.

What this could mean

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

Active substance
SHR-A1811 (an antibody-drug conjugate given by IV infusion)
What this could lead to
If successful, this could point toward a new treatment option for people with advanced solid tumors that have HER2 mutations or overexpression.
What could go wrong
This is an early Phase 1 trial focused on safety and dosing, not yet proven to work. Side effects are possible, and the drug may not shrink tumors or improve survival.
