Summary

This early-stage trial is testing an experimental drug called SIM0348, given alone or with another drug (sintilimab), in adults with advanced solid tumors that have not responded to standard treatments. The main goals are to check the safety and tolerability of the drug, how it moves through the body, and whether it shows any signs of shrinking tumors. Participants receive the drug through an IV infusion in repeated cycles until the disease progresses or they no longer benefit.

What this could mean

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

Active substance
SIM0348, an experimental drug given by IV infusion, tested alone and in combination with sintilimab
What this could lead to
If successful, this could lead to a new treatment option for people with advanced solid tumors who have exhausted standard therapies.
What could go wrong
This is an early-phase trial with a small number of participants, so safety and effectiveness are not yet established. The drug may not work or may cause significant side effects.
