New pill takes on Hard-to-Treat cancers in first human trial
NCT ID NCT05159700
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial tests an experimental oral drug called PRJ1-3024 in 39 adults with advanced solid tumors that have not responded to standard treatments. The main goal is to check safety and find the right dose. Researchers will also look for early signs that the drug may 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
- PRJ1-3024 (oral capsule)
- What this could lead to
- If this drug is safe and shows signs of shrinking tumors, it could lead to a new treatment option for people with advanced solid cancers that have stopped responding to other therapies.
- What could go wrong
- This is a very early Phase 1 trial with only 39 participants. The main goal is safety, not effectiveness. Many drugs fail at this stage, and side effects may be serious.
