New hope for tough cancers: experimental drug DPTX3186 enters first human trial
NCT ID NCT07312903
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage study tests an experimental oral drug called DPTX3186 in 40 adults with advanced solid tumors (like colorectal, gastric, lung, or triple-negative breast cancer) that are linked to a specific cell signal called Wnt. These participants have no other approved treatments left. The main goal is to check the drug's safety and how the body processes it, not yet to prove it works.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- DPTX3186 (an experimental oral drug)
- What this could lead to
- If it works, this could point toward a new treatment option for certain hard-to-treat cancers that have run out of standard therapies.
- What could go wrong
- This is a very early Phase 1 trial with only 40 participants, so the main goal is safety, not effectiveness. Many drugs fail at this stage, and side effects are unknown.
