Experimental mRNA inhalation therapy targets rare lung disease

NCT ID NCT06600425

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

Summary

This early-phase study tests an inhaled mRNA therapy called RCT1100 in 7 adults with primary ciliary dyskinesia caused by DNAI1 gene mutations. The goal is to see if the treatment is safe and can help restore ciliary function in the lungs. It is a small, open-label trial focused on safety and preliminary effectiveness.

What this could mean

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

Active substance

RCT1100 mRNA therapy

What this could lead to

If successful, this could point toward a treatment that improves ciliary function and respiratory symptoms in people with primary ciliary dyskinesia.

What could go wrong

This is a very early, small Phase 1b study with only 7 participants, so results may not apply broadly. The therapy is still experimental and safety is the main focus.
