First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial tests an experimental drug called RSC-1255, given alone or with hydroxychloroquine, in people with advanced solid tumors (like lung, colon, or pancreatic cancer) who have run out of standard options. The study has two parts: first, finding a safe dose, and then checking for early signs of effectiveness. About 134 participants will take part.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
RSC-1255 (an experimental drug taken orally) alone or with hydroxychloroquine
What this could lead to
If successful, this could point toward a new treatment option for people with advanced cancers that have not responded to standard therapies.
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 may cause side effects. It is too soon to know if it will work.
