Can a single eye injection shrink melanoma and save sight?
NCT ID NCT07747935
First seen Aug 05, 2026 · Last updated Aug 06, 2026 · Updated 1 time
Summary
This early-phase trial is testing an investigational drug called RBP-01 (sotrastaurin), given as an injection into the eye, for people with primary uveal melanoma—a rare cancer of the eye. The study aims to see if the drug is safe and whether it can shrink the tumor enough to avoid eye removal (enucleation) or reduce the risk of vision loss from standard radiation therapy. Participants will receive the injection before their planned standard treatment, and researchers will monitor for side effects and measure tumor response.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- an intravitreal injection of sotrastaurin (RBP-01)
- What this could lead to
- If it works, this could offer a way to shrink eye tumors before standard treatment, potentially saving the eye and preserving vision in people with uveal melanoma.
- What could go wrong
- This is an early-stage trial with a small number of participants, so the treatment may not prove effective or safe. Possible risks include side effects from the injection and the tumor not responding.
