New 'Tri-Specific' antibody takes aim at Hard-to-Treat cancers
NCT ID NCT07055594
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new drug called SOA101, a special antibody that can attach to both cancer cells and immune cells to help the immune system attack tumors. It is for people with advanced solid tumors (like lung, ovarian, or breast cancer) who have no other standard treatment options. The trial has two phases: first, finding the safest dose, and then checking if the drug shrinks tumors. About 76 participants will take part.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SOA101 (a trispecific antibody that targets cancer cells and immune cells)
- What this could lead to
- If successful, this could lead to a new treatment option for people with advanced solid tumors who have run out of standard therapies.
- What could go wrong
- This is an early-phase trial with a small number of participants, so the drug may not prove effective or safe enough for wider use. Side effects from immune activation are possible.
