Soluble Guanylate Cyclase Stimulator

Riociguat for Pulmonary Hypertension Due to Heart Failure (LEPHT Trial)

Phase 2
Waitlist Available
Research Sponsored by Bayer
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Male and female patients with symptomatic pulmonary hypertension due to left ventricular systolic dysfunction despite optimized heart failure therapy
Be older than 18 years old
Must not have
Types of pulmonary hypertension other than group 2.1 of Dana Point Classification
Timeline
Screening 3 weeks
Treatment Varies
Follow Up at visit 6 (16 weeks)

Summary

This trial will test if increasing doses of Riociguat are safe and improve symptoms in patients with PH caused by heart failure.

Who is the study for?
This trial is for men and women who have pulmonary hypertension due to weak heart pumping (left ventricular systolic dysfunction) despite being on the best treatment for heart failure. It's not open to those with other types of high blood pressure in the lungs besides group 2.1 as classified at Dana Point.
What is being tested?
The study is testing Riociguat, a medication that might improve symptoms and overall health in patients with certain kinds of lung-related high blood pressure linked to heart issues. Participants will either receive Riociguat or a placebo without knowing which one they're getting.
What are the potential side effects?
Riociguat can cause side effects like low blood pressure, headache, dizziness, upset stomach or indigestion, swelling of legs or arms, and potential risks during pregnancy.
