First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase trial is testing an experimental drug called DA-3501 in 51 adults with advanced stomach, gastro-esophageal junction, or pancreatic cancers that have a specific protein (CLDN18.2). Participants receive the drug by IV once every three weeks. The main goals are 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
DA-3501 (an experimental drug given by IV every three weeks)
What this could lead to
If it works, this could point toward a new treatment option for people with advanced stomach or pancreatic cancers that express a specific marker (CLDN18.2).
What could go wrong
This is a very early, first-in-human trial with only 51 participants. The drug may not shrink tumors or could cause serious side effects. Success is far from guaranteed.
