NCT ID NCT07142291

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

Summary

This phase 2 trial is testing whether an inhaled drug called cromolyn (PHENOGENE-1A) can help people with mild-to-moderate ALS when added to standard care. About 105 participants will receive either a low dose, high dose, or placebo for 24 weeks. Researchers will measure changes in daily function, breathing, and safety.

What this could mean

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

Active substance

Cromolyn sodium (PHENOGENE-1A) taken by oral inhalation twice daily

What this could lead to

If it works, this could slow functional decline in people with mild-to-moderate ALS, potentially adding months of better quality of life.

What could go wrong

This is an early phase 2 trial with only 105 people. It may fail to show benefit, and cromolyn's effects on ALS are unproven. Side effects from the inhaled drug are possible.
