RECRUITING

Spironolactone for Pulmonary Arterial Hypertension

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:18 Years to 100 Years
Sexes Eligible for Study:ALL
Accepts Healthy Volunteers:No
Standard Ages:ADULT, OLDER_ADULT
Inclusion CriteriaExclusion Criteria
  1. 1. WHO Group 1 PH patients on either no medical therapy or stable medical therapy for at least the past 4 weeks (defined as no new PAH-specific therapy, no change in the dose of current PAH-specific therapy and no change in NYHA/WHO functional classification within the past 4 weeks) are eligible. The following parameters on RHC are required to meet the hemodynamic definition of PAH:
  2. 1. mean pulmonary artery pressure of \> 25 mmHg at rest,
  3. 2. pulmonary capillary wedge pressure of less than or equal to 15 mmHg (or a left ventricular end-diastolic pressure of less than or equal to 12 mmHg) and
  4. 3. pulmonary vascular resistance of \> 3 Wood units (240 dyn.s.cm\^-5).
  1. 1. Patients with WHO Group 1 PH and evidence of right heart failure as defined by:
  2. 1. NYHA/WHO class IV symptoms and
  3. 2. Echocardiographic evidence of severe RV dysfunction and
  4. 3. Clinical evidence of right heart failure which may include, but is not limited to elevated jugular venous pressure, ascites, and lower extremity edema
  5. 2. Patients with WHO Group 1 pulmonary hypertension and a prior diagnosis of cirrhosis with portal hypertension as evidenced by a history of ascites, hepatic encephalopathy and/or varices prior to enrollment
  6. 3. Patients with WHO Group 1 pulmonary hypertension and evidence of active infection, (HIV patients with two consecutive viral loads of \< 500 on their most recent determinations within the past 12 months will be considered to have inactive infection)
  7. 4. Patients with WHO Group 1 pulmonary hypertension who have taken spironolactone or eplerenone within the last 30 days
  8. 5. Known or suspected allergy to spironolactone
  9. 6. Pregnant or breastfeeding women (all women of childbearing potential will be required to have a screening urine or blood pregnancy test)
  10. 7. Age \<18 years
  11. 8. Inability to provide informed written consent for participation in the study
  12. 9. Chronic kidney disease (an estimated glomerular filtration rate of \< 35 mL/min/1.73m\^2 of body surface area)
  13. 10. Serum potassium at the time of enrollment of \> 5 mEq/L
  14. 11. Concurrent use of an ACE inhibitor and angiotensin II receptor blocker
  15. 12. Women currently taking drospirenone-containing oral contraceptives
  16. 1. Implanted cardiac pacemaker or defibrillator
  17. 2. Cochlear Implants
  18. 3. Ocular foreign body (e.g. metal shavings)
  19. 4. Embedded shrapnel fragments
  20. 5. Central nervous system aneurysm clips
  21. 6. Implanted neural stimulator
  22. 7. Any implanted device that is incompatible with MRI
  23. 8. Unsatisfactory performance status as judged by the referring physician such that the subject could not tolerate an MRI scan. Examples of medical conditions that would not be accepted would include unstable angina and severe dyspnea at rest
  24. 9. Subjects requiring monitored sedation for MRI studies
  25. 10. Subjects with a condition precluding entry into the scanner (e.g. morbid obesity, claustrophobia, etc.)
  26. 11. Subjects with severe back-pain or motion disorders who will be unable to tolerate supine positioning within the MRI scanner and hold still for the duration of the examination.
  27. 1. History of severe allergic reaction to gadolinium contrast agents despite pre- medication with diphenhydramine and prednisone
  28. 2. Chronic kidney disease (an estimated glomerular filtration rate of \< 60 mL/min/1.73m\^2 of body surface area)
