New hope for kids with rare lung condition: inhaled protein therapy in trial

NCT ID NCT06431776

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

Summary

This study tests an inhaled drug called molgramostim in children aged 6 to 18 with autoimmune pulmonary alveolar proteinosis (aPAP), a rare disease where protein builds up in the lungs and makes breathing hard. All 5 participants will take the drug daily via a nebulizer for 12 months. Researchers will check lung function, exercise ability, and quality of life to see if the treatment helps and is safe.

What this could mean

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

Active substance

molgramostim (a lab-made protein that helps immune cells clear protein buildup in the lungs)

What this could lead to

If it works, this could point toward a treatment for children with a rare lung disease that currently has limited options.

What could go wrong

This is a very small, early-phase trial with only 5 children, so results may not apply to everyone. The treatment requires daily nebulizer use for a year, and side effects are still being studied.
