NCT ID NCT06809114
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage study is testing a new drug called AT03-65 in 83 adults with advanced solid tumors that have not responded to standard treatments. The main goal is to check safety and find the right dose, while also looking for early signs that the drug might shrink tumors. Participants will receive the drug until their disease gets worse or side effects become too severe.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
AT03-65 (an antibody drug conjugate)
What this could lead to
If it works, this could point toward a new treatment option for people with advanced solid tumors that have stopped responding to standard therapies.
What could go wrong
This is a very early Phase 1 trial with only 83 participants, so it is primarily checking safety. The drug may not shrink tumors or could cause serious side effects.
