Summary

This study tests a new drug called MHB039A, a bispecific antibody, in 196 people with advanced solid tumors that have not responded to standard treatments. The goal is to see if the drug is safe and effective. Participants receive the drug and are monitored for side effects and tumor response.

What this could mean

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

Active substance
MHB039A (a bispecific antibody)
What this could lead to
If it works, this could point toward a new treatment option for people with advanced solid tumors that have not responded to standard therapies.
What could go wrong
This is an early-phase trial (Phase I/II) with a small number of participants, so the drug may not prove effective or safe. Side effects and dose-limiting toxicities are being closely monitored.
