New drug YL201 enters human trials for Hard-to-Treat cancers
NCT ID NCT05434234
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests a new drug called YL201 in people with advanced solid tumors that have stopped responding to standard treatments. The trial has two parts: first, finding a safe dose, then testing that dose in more patients with specific cancer types. YL201 is given by IV every three weeks, sometimes combined with another cancer drug called atezolizumab. The goal is to see if it is safe and can 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
- YL201 (a drug given by IV infusion every 3 weeks, alone or with atezolizumab)
- What this could lead to
- If successful, this could lead to a new treatment option for people with advanced solid tumors that have not responded to other therapies.
- What could go wrong
- This is an early, first-in-human study, so safety and effectiveness are not yet known. The drug may cause side effects or not shrink tumors as hoped.
