Small study tackles nasty side effect of lung drug

NCT ID NCT06200714

First seen May 20, 2026

Summary

This study followed 18 people in Spain with idiopathic pulmonary fibrosis (IPF) or other progressive lung scarring who were taking nintedanib (OFEV) and had developed diarrhea. The goal was to see if the diarrhea could be controlled after 12 weeks while staying on the full dose. Researchers tracked how many patients had fewer than 3 loose stools per day. It is an observational study, meaning no new treatment was tested—just real-world data collection.

What this could mean

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

Active substance

nintedanib (OFEV)

What this could lead to

If successful, this could help doctors manage a common side effect of nintedanib, allowing patients to stay on their lung fibrosis treatment with less discomfort.

What could go wrong

This is a very small observational study (18 people) with no control group, so results may not apply to everyone. It only looks at diarrhea control, not whether the drug works for the lung disease.
