First-in-Human antibody MHB118C tested against advanced solid tumors
NCT ID NCT07045454
First seen Oct 09, 2026 · Last updated Oct 09, 2026
Summary
Researchers are testing an experimental antibody injection called MHB118C in adults with advanced solid tumors that have not responded to standard treatments. The trial aims to find out whether the drug is safe, what side effects it causes, and what dose people can tolerate. Participants receive MHB118C through an IV every three weeks and continue treatment as long as it is safe and their cancer does not worsen. The study also measures how the body processes the drug and looks for early signs that it might shrink tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- an experimental antibody injection called MHB118C
- What this could lead to
- If it works, MHB118C could offer a new treatment option for people whose advanced solid tumors have stopped responding to standard therapy.
- What could go wrong
- This is a first-in-human study, so researchers know little about how MHB118C behaves in people. The drug may cause serious side effects or fail to shrink tumors, and any benefit seen in early testing may not hold up in larger studies.
