New Antibody-Drug conjugate targets Hard-to-Treat cancers
NCT ID NCT06465069
First seen Jun 27, 2026 · Last updated Sep 04, 2026 · Updated 11 times
Summary
This early-stage trial tests a new drug called LY4052031, which is designed to deliver a cancer-killing agent directly to tumor cells that have a protein called Nectin-4. The study includes 420 adults with advanced or metastatic solid tumors such as bladder, breast, lung, and others. The goal is to find a safe dose and see if the drug 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
- LY4052031 (an antibody-drug conjugate targeting Nectin-4)
- What this could lead to
- If successful, this could lead to a new treatment option for several advanced cancers that are hard to treat.
- What could go wrong
- This is an early Phase 1 trial, so the drug may not be effective or could have serious side effects. It will take years to know if it works.
