Association Between Biomarkers and eGFR Decline in Pulmonary Hypertension

Study Purpose

The objective of this study is to examine the association between urinary and plasma biomarkers and the change of estimated glomerular filtration rate (eGFR) in patients with pulmonary hypertension (PH) as a tool to identify patients at high risk for short-term eGFR decline.

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.

Trial Details

Trial ID:

This trial id was obtained from, 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.

Pulmonary Hypertension
Additional Details

PH is a severe, progressive disease associated with right ventricular dysfunction, right-sided heart failure (HF) and death. Chronic kidney disease (CKD) is approximately 35% in patients with PH, and its presence is associated with an enhanced risk for adverse outcomes, with the risk increasing incrementally with declining kidney function. Poor right ventricular function may increase venous congestion, alter ventricular interdependence, decrease effective cardiac output and activate the renin-angiotensin- aldosterone system, thereby aggravating kidney disease. To date, biomarkers for assessment of CKD progression in PH are lacking. The objective of this study is to examine the association between urinary and plasma biomarkers and the change of eGFR in patients with PH, aiming to identify those at high risk for short-term eGFR decline.
