Early Treatment of Borderline Pulmonary Arterial Hypertension Associated With Systemic Sclerosis (SSc-APAH) A Randomized, Controlled, Double-blind, Parallel Group, Proof-of-concept Trial EDITA
In Brief
A Phase 2 clinical trial evaluating Ambrisentan and Placebo for Systemic Sclerosis and Pulmonary Hypertension. Completed, enrolled 38 participants across 1 site.
Detailed Summary
Trial Design Patients with borderline PAH indicated by borderline mPAP values will be included in this single centre study. This clinical investigation is performed as a Proof-of-Concept (PoC) investigator initiated trial (IIT) using a prospective, randomized, double-blind, parallel group, placebo-controlled, phase IIA clinical study design. On their first visit their medical history will be obtained and physical examination will be conducted. Moreover, an electrocardiogram (ECG), laboratory testing (NT-proBNP, uric acid and other laboratory tests), echocardiography at rest and right heart catheterization will be carried out. If patients have been identified within the last 6 months before screening investigations by right heart catheterization, the measurements are considered valid as baseline investigations and will not be repeated. If patients fulfill the inclusion criteria and still suffer from borderline mPAP values they will be invited to join the study. The clinical investigations will begin within 28 days. The prospective study will comprise a 6 months study period (180 ±2 weeks) plus the screening phase up to 28 days and a follow-up phase of 30 ±7 days.

Interventions
Titration: As common practice of the clinic, the patient will adapt the dose from 5 mg to 10 mg after 1 to 4 weeks according to tolerability and after consultation (by phone or personally) with one of the investigators. Additionally, at each study visit the investigator needs to decide, based on the patient's well-being, patients´ assessment, safety parameters, and tolerance of ambrisentan, if the study medication should be modified. The respective decision (increase, maintain or decrease dose) must be documented. Maximum dose allowed: not to exceed 10 mg/day. Administration: Ambrisentan and placebo will be administered orally with or without food intake.
Placebo tablet (one to two tablets corresponding to one to two verum tablets)
