Small study explores real-world switch to riociguat for tough PAH cases

NCT ID NCT07374302

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This observational study will review medical records of 15 adults with pulmonary arterial hypertension (PAH) who switched from one medication (a PDE5 inhibitor) to riociguat while already on triple therapy. The goal is to see if this switch improves exercise ability, symptoms, and blood markers at 6 months. Because it is a retrospective chart review, no new treatments are given, and the results will only describe what happened in routine care.

What this could mean

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

Active substance

riociguat

What this could lead to

If results are positive, this could suggest that switching to riociguat is a useful option for PAH patients not doing well on standard triple therapy.

What could go wrong

This is a very small (15 people), single-center, retrospective study, so results may not apply widely. It only observes routine care, so it cannot prove cause and effect.
