RECRUITING Phase 2

Spironolactone for Pulmonary Arterial Hypertension

NCT01712620 · View on ClinicalTrials.gov ↗

Study Summary

Background: \- High blood pressure in the lungs, known as pulmonary arterial hypertension (PAH), is a rare disorder. In spite of recent advances in treatment, the death rate remains unacceptably high. Lung blood vessel function can be harmed by progressive injuries, such as inflammation, leading to worsening of the disease. A drug called spironolactone has been known to improve blood vessel function and reduce inflammation. Some people with PAH take spironolactone to help treat fluid retention. However, its effect on inflammation and blood vessel function in patients with PAH is not known. Researchers want to see if spironolactone can help these conditions in people with PAH. Objectives: \- To test the effectiveness of spironolactone in treating pulmonary arterial hypertension. Eligibility: \- Individuals at least 18 years of age with pulmonary arterial hypertension. Design: * This study will last for 24 weeks. Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. * Participants will take either spironolactone or a placebo. They will take their study drug or placebo for 7 weeks. Treatment will be monitored with regular blood tests. * In Week 8, participants who have had no reaction to the treatment will receive a higher dose of the drug or placebo. * In Week 12, participants will have a study visit with heart and lung function tests. They will also have a 6-minute walk test, and provide blood and urine samples. * After additional study visits for blood samples, participants will have a final visit in Week 24. The tests from Week 12 will be repeated at this visit.

What the Registry Record Tells You About NCT01712620

The ClinicalTrials.gov registry entry for NCT01712620 describes a study currently listed as recruiting. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 70 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institutes of Health Clinical Center (CC), which has 209 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.

The record links to 1 condition, with Pulmonary Arterial Hypertension appearing as the primary indexed condition, and to 2 interventions — of which Placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.

Geographic footprint matters for practical reasons: NCT01712620 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
