Summary
This early-phase trial tested a new drug called IBI133 in 19 adults with advanced solid tumors that cannot be removed by surgery or have spread. The main goals were to find a safe dose and check for side effects. Researchers also looked at how the drug moves through the body and whether it shows any signs of shrinking tumors.
