NCT ID NCT07644377

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study looks at people with a rare lung condition called CTEPH who have done well after a procedure (balloon angioplasty) and are taking a drug called riociguat. The goal is to see if stopping the drug is as safe as continuing it. About 150 participants will be randomly assigned to stop or continue riociguat and be followed for at least a year to check for worsening health.

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 successful, this could show that many CTEPH patients can safely stop taking riociguat after balloon angioplasty, reducing medication burden and side effects.

What could go wrong

This is a Phase 3 trial, but it's still early and small (150 participants). Stopping the drug might lead to worsening symptoms or complications in some patients.
