New drug MRG007 enters early human testing for Hard-to-Treat cancers
NCT ID NCT07066657
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 5 times
Summary
This early-phase trial tests a new drug called MRG007 (ARR-217) in people with advanced solid tumors that have not responded to standard treatments. The study aims to find a safe dose and check if the drug can shrink tumors. About 405 participants with colorectal, gastric, or pancreatic cancer will take part across multiple centers.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- MRG007 (ARR-217)
- What this could lead to
- If it works, this could point toward a new treatment option for people with advanced solid tumors like colorectal, gastric, or pancreatic cancer.
- What could go wrong
- This is a very early Phase 1 trial, so the main goal is safety, not effectiveness. The drug may not shrink tumors or could cause serious side effects.
