New RNA drug aims to reduce blood removal in polycythemia vera patients

NCT ID NCT05499013

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a new drug called SLN124 in 69 adults with polycythemia vera, a condition where the body makes too many red blood cells. The drug works by blocking a protein that controls iron use, which may lower red blood cell production and reduce the need for regular blood removal (phlebotomy). The trial has two phases: first, an open-label dose-finding part, then a randomized double-blind phase where some patients get the drug and others get a placebo.

What this could mean

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

Active substance

SLN124 (a small interfering RNA drug that targets a protein involved in iron regulation)

What this could lead to

If it works, this could reduce the need for frequent blood removal (phlebotomy) and help manage polycythemia vera more effectively.

What could go wrong

This is an early-phase trial with only 69 participants, so results may not apply to everyone. The drug may cause side effects or fail to show clear benefit.
