Eligibility
Inclusion criteria
Inclusion criteria: • A diagnosis of PAH group 4 or group 1 in any of the following subtypes: o Idiopathic PAH (iPAH) o Heritable PAH (hPAH) o Connective tissue disease associated PAH (aPAH) o In case of PAH in group 4, no further invasive treatment including pulmonary endarterectomy or pulmonary balloon angioplasty must be planned at time of inclusion. • Symptomatic PAH in WHO functional class II-III as assessed by the screening clinician. • Clinically stable patients on pulmonary vasodilator treatment with PDE5i, ERA, PA/IPA alone or in combination without considerations from the treating physician team towards treatment escalation and a treatment duration of at least four weeks. Clinical stability defined as stable symptoms without progression as assessed by treating clinician and without the need for unplanned hospital admissions due to worsening PAH within three months of screening. • Fertile women (=65 years) yes F.1.3.1 Number of subjects for this age range 10
Exclusion criteria
Exclusion criteria: • Known allergy to the study medication • Treatment with an SGLT2i within 6 months prior to baseline • Type 1 or type 2 diabetes • Impaired renal function with an eGFR < 30 mL/min/m2 within four weeks of screening • Severe liver dysfunction (Child-Pugh class c) • Listed for lung transplantation at the time of screening • Planned initiation of iv prostacyclin therapy/ IPA or current dose escalation planned • Planned pulmonary endarterectomy or pulmonary balloon angioplasty. • LVEF < 50% • Diagnosis of PAH group 2, 3 or 5
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The objective of this study is to evaluate the effects of oral dapagliflozin (Forxiga®) treatment versus placebo in clinically stable patients with PAH on background vasodilator combination therapy on cardio-pulmonary exercise capacity, pulmonary vascular hemodynamics, RV function and metabolomic profile of the pulmonary vascular endothelium.;Secondary Objective: Not applicable;Primary end point(s): Change in maximum oxygen consumption (VO2 max) measured by cardiopulmonary exercise testing from baseline to follow up after ninety days between dapagliflozin and placebo.;Timepoint(s) of evaluation of this end point: 3 months / 90 days | — |
Secondary
