New drug ZL-1310 tested in patients with Hard-to-Treat cancers
NCT ID NCT06885281
First seen Jun 25, 2026 · Last updated Aug 21, 2026 · Updated 6 times
Summary
This study tests a new drug called ZL-1310 in adults with advanced neuroendocrine carcinomas (a type of solid tumor) that have worsened after platinum-based chemotherapy. The trial has two parts: Phase 1b checks safety and side effects, while Phase 2 looks at whether the drug shrinks tumors. About 112 participants will receive ZL-1310 and be monitored for response and side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ZL-1310
- What this could lead to
- If it works, this could point toward a new treatment option for people with advanced neuroendocrine carcinomas that have stopped responding to standard chemotherapy.
- What could go wrong
- This is an early-phase trial (Phase 1b/2) with only 112 participants, so it is too soon to know if ZL-1310 is safe or effective. Side effects are unknown, and the drug may not shrink tumors or improve survival.
