Overview
Brief Summary
The goal of this clinical trial is to learn if empagliflozin works to treat patients with pulmonary arterial hypertension. It will also learn about the safety of empagliflozin. The main questions it aims to answer are:
Based on standard treatment, does empagliflozin reduce pulmonary artery pressure and improve cardiac function in patients with pulmonary arterial hypertension? What medical problems do participants have when taking empagliflozin? Researchers will compare empagliflozin to a placebo (a look-alike substance that contains no drug) to see if empagliflozin works to treat patients with pulmonary arterial hypertension.
Participants will:
Take empagliflozin or a placebo every day for 12 weeks Visit the clinic once every 4 weeks for checkups and tests Keep a diary of their symptoms and the drug taking situation

Eligibility Criteria
Inclusion Criteria
- •At least 18 years old.
- •Sign the informed consent form.
- •Subjects who are willing and able to comply with the requirements of prescribed visits, treatment plans, laboratory examinations and other research procedures.
- •PAH with symptoms was initially diagnosed and belonged to one of the following subgroups:
- •A. Idiopathic pulmonary hypertension (IPAH); B. hereditary pulmonary hypertension (HPAH); C drug or toxin-induced PAH, based on previous exposure to drugs, chemicals or toxins, such as fenfluramine derivatives, other appetite suppressants, toxic rapeseed oil or L- tryptophan.
- •D. PAH is accompanied by:
- •A) connective tissue disease B) Congenital systemic-pulmonary shunt (surgical correction must be performed at least one year before screening, and there is no or no clinically insignificant systemic-pulmonary shunt \[1.0≤ lung-systemic blood flow ratio (QP/QS)≤1.5\]), according to the opinion of the researcher.
- •Received right heart catheterization (RHC) at the time of screening or within 5 years before screening (if RHC is not performed, it will be performed during screening), which is consistent with the diagnosis of PAH and meets all the following criteria:
- •A. mean pulmonary artery pressure (papm) \> 20mmhg (at rest) B pulmonary arteriole wedge pressure (PAWP)≤15 mmHg (if reliable PAWP data cannot be obtained, left ventricular end diastolic pressure \[LVEDP\]≤15 mmHg).
- •C pulmonary vascular resistance (PVR) \> 2.00 wood units (\> 160 dynes/sec/cm5).
Exclusion Criteria
- •1\) Subjects shall not have the following three or more risk factors for left ventricular dysfunction: Body mass index (BMI)≥30 kg/m2 History of systemic hypertension
- •There is any of the following evidence to prove the history of major coronary artery disease:
- •A coronary angiographic evidence of a history of myocardial infarction or percutaneous coronary intervention or coronary artery disease (at least one coronary artery stenosis \> 50%); B. Positive results of exercise provocation test and image evidence; C. previous coronary artery bypass surgery; D. stable angina pectoris; 2) Pulmonary function tests (PFTs) conducted within 180 days before or during the screening showed mild or above lung diseases. Subjects who meet any of the following criteria will be excluded: A. forced expiratory volume in the first second (FEV1)\<60% (expected value); or B total lung volume (TLC) \< 60% of the estimated value. 3) The evidence of thromboembolic disease is confirmed by lung ventilation/perfusion (V/Q) scanning or local standard diagnosis and treatment evaluation at the time of diagnosis or after diagnosis of PAH.
- •4\) Severe chronic liver disease (i.e. Child-pugh grade C), portal hypertension, cirrhosis or complications of cirrhosis/portal hypertension (e.g., history of varicose bleeding, history of hepatic encephalopathy).
- •5\) Confirm the active infection of hepatitis B virus (HBV) or hepatitis C virus (HCV).
- •6\) Subjects whose alanine aminotransferase (ALT) or aspartate aminotransferase (AST) level is more than or equal to 3 times the normal upper limit value (ULN) or whose total bilirubin is more than or equal to 2 times ULN at the time of screening.
- •7\) Chronic renal insufficiency at screening, which is defined as serum creatinine \> 2.5 mg/dL or requiring dialysis support.
- •8\) Hemoglobin concentration \< 9 g/dL during screening. 9) diabetes. 10) cardiac function grade IV (NYHA classification) 11) The subject has been treated with IV or SC prostacyclin pathway drugs (for example, epoprostol, triprostinil or iloprost) at any time before baseline (allowed to be used in pulmonary vasodilation test).
- •12\) The subject has pulmonary vein occlusion disease. 13) Diagnosed and/or treated with malignant tumor within 5 years before screening, but excluding localized non-metastatic basal cell carcinoma or squamous cell carcinoma of the skin, or radical resection of cervical carcinoma in situ.
- •14\) At the time of screening, there was a history of alcohol or drug abuse within 6 months.
