Dapagliflozin in Pulmonary Arterial Hypertension

Study Purpose

The purpose of this study is to investigate the effects of dapagliflozin on exercise capacity and hemodynamics in patients with pulmonary arterial hypertension

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All

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

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
