Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to assess the efficacy and safety of the study drug, levosimendan (given orally), compared to placebo in participants with pulmonary hypertension with heart failure with preserved left ventricular ejection fraction (PH-HFpEF) as measured by the change in 6-Minute Walk Distance.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Approximately 540 participants will be randomized in a 2:1 ratio to receive an oral dose of levosimendan or placebo. Participants will be eligible for an open label extension (OLE) of 52-weeks.
