New antibody EPI-326 enters first human trials for tough cancers
NCT ID NCT07462377
First seen Jun 25, 2026 · Last updated Sep 11, 2026 · Updated 5 times
Summary
This early-phase study tests a new drug called EPI-326 in about 110 people with advanced lung or head & neck cancers that have specific EGFR mutations. The drug is a bispecific antibody designed to target cancer cells more precisely. The main goals are to check safety, find the right dose, and see early signs of tumor shrinkage.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- EPI-326 (a bispecific antibody given by IV infusion)
- What this could lead to
- If it works, this could point toward a new treatment option for certain lung and head & neck cancers that have not responded to other therapies.
- What could go wrong
- This is a very early Phase 1 trial with only 110 people, focused on safety and dosing. It may not show strong anti-tumor effects, and side effects are unknown.
