Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a randomised, double-blind, placebo-controlled, multicentre, multinational, prospective study in patients with operable chronic thromboembolic pulmonary hypertension (CTEPH) prior to pulmonary endarterectomy (PEA) with high preoperative pulmonary vascular resistance (PVR). Patients will be randomised in a 1:1 ratio to receive riociguat or matching placebo for 3 months before undergoing PEA. The primary objective of this study is to assess the efficacy of riociguat on preoperative PVR compared to placebo in patients with operable CTEPH.
