  • A Study of MK-5475 in Pulmonary Arterial Hypertension

    “Volunteer for research and contribute to discoveries that may improve health care for you, your family, and your community!”

    open to eligible people ages 18-75

    This is a two-part (Phase 2/Phase 3) study of MK-5475, an inhaled soluble guanylate cyclase stimulator, in participants with pulmonary arterial hypertension (PAH). The first part (Phase 2) will assess three different doses of MK-5475 compared to placebo in a base period of 12 weeks, followed by comparison of three different doses of MK-5475 during an optional 24 month extension period. The treatment dose with the best efficacy and safety profile in the phase 2 cohort base period will be selected for use in the second part (Phase 3) of the study. The primary hypothesis of Phase 2 is that at least one MK-5475 dose is superior to placebo in reducing pulmonary vascular resistance (PVR) from baseline at week 12. The purpose of the second part (Phase 3) of the study is to confirm the efficacy, safety, and tolerability of MK-5475 at the selected dose compared to placebo during a 12 week base period followed by an extension period of up to 5 years. The primary hypothesis of Phase 3 is that MK-5475 is superior to placebo in increasing 6-minute walk distance (6MWD) from baseline at week 12.

  • Right Ventricular Pacing in Pulmonary Arterial Hypertension

    open to eligible people ages 18-75

    In pulmonary arterial hypertension (PAH), progressive pulmonary vascular remodeling leads to supraphysiologic right ventricular (RV) afterload. Pharmacologic trials have shown that aggressive upfront treatment reversing pulmonary vascular remodeling successfully increases RV function and improves survival. To date, however, there are no proven treatments that target RV contractile function. Echocardiographic studies of RV dysfunction in the setting of pressure overload have demonstrated intra and interventricular dyssynchrony even in the absence of overt right bundle branch block (RBBB). Electrophysiologic studies of patients with chronic thromboembolic disease (CTEPH) at the time of pulmonary endarterectomy have shown prolongation of action potential and slowed conduction in the right ventricle which has correlated with echocardiographic measures of dyssynchrony. Cardiac MRI measures of RV strain in patients with PAH demonstrated simultaneous initiation of RV and left ventricular (LV) contraction, but delayed peak RV strain suggesting that interventricular dyssynchrony is a mechanical rather than electrical phenomenon. Prior studies of RV dysfunction in an animal model, computer model, congenital heart disease, and CTEPH have suggested acute hemodynamic benefits of RV pacing. However, RV pacing has not been studied in patients with PAH. Furthermore, it remains unclear if pacing particular regions of the RV can achieve a hemodynamic benefit and what cost this hemodynamic improvement may incur with regards to myocardial energetics and wall stress. Therefore, the investigators propose to examine RV electrical activation in PAH, map the area of latest activation, and then evaluate the hemodynamic and energetic effects of RV pacing in these patients.

  • A Study to Learn About How Well Riociguat Works, How Safe it is and How it is Used Under Real World Conditions in Patients in the United States Who Are Receiving Riociguat for High Blood Pressure in the Arteries That Carry Blood From the Heart to the Lungs (Pulmonary Arterial Hypertension, PAH)

    open to eligible people ages 18 years and up

    Pulmonary arterial hypertension (PAH) is a type of high blood pressure in the arteries that carry blood from the heart to the lungs. PAH occurs when the openings in the blood vessels of the lungs get smaller and smaller. These smaller openings can be caused by the following: - The walls of the arteries tightening - The walls of the arteries becoming stiff and narrow from an overgrowth of cells The increased pressure in the pulmonary arteries strains the right side of the heart and it begins to fail, causing difficulty breathing and other symptoms. As PAH progresses, symptoms get worse. There is no cure for PAH, but several medications like endothelin receptor antagonists (ERAs), prostacyclin analogues (PCAs) and riociguat, a soluable guanylate cyclase stimulator, are available to help slow the progression of changes in the pulmonary arteries and help reduce symptoms. Riociguat can be taken together with ERAs and PCAs. In this study, the researchers want to learn about how well riociguat works, how safe it is when patients take it in 1 of these ways: - alone - with ERA - with PCA - with ERA and PCA The dosage for each patient will be decided by their doctor. The researchers will review information collected from the patients who have decided with their doctor to start riociguat treatment for their PAH. The study will include about 500 patients in the United States who are at least 18 years old. All of the patients will have either just started taking riociguat or will have been taking it for less than 3 months No investigational products will be administered in this study. Patients will be treated with the Standard of Care (SOC) for PAH. The SOC is the currently appropriate treatment in accordance with scientific evidence and agreed upon in collaboration between medical experts for PAH. There will be no study-mandated visits or treatments. The patients will be in the study for up to 2 years. During this time, they will visit their doctor every 3 to 6 months as part of the Standard of Care. At these visits, the patients will answer questions about their PAH symptoms and whether they have any medical problems. They will also do exercise tests to see how well they are able to breathe and how tired they get while exercising. The doctors will perform other usual examinations which are part of the Standard of Care such as echocardiograms (images of the heart to show how the heart is working) and a right heart catheters (to measure the pressures in the heart) and will take the usual blood and urine samples.

  • Pediatric Pulmonary Hypertension Network (PPHNet) Informatics Registry

    open to eligible people ages up to 21 years

    Patients are being asked to be in this research study because medical researchers hope that by gathering information about a large number of children with pulmonary hypertension over time, their understanding of the disease process will increase and lead to better treatment. Investigators believe that pulmonary hypertension in children is different than pulmonary hypertension in adults and this study will help us understand those differences.

  • Pharmacokinetics, Pharmacodynamics, and Safety Profile of Understudied Drugs Administered to Children Per Standard of Care (POPS)

    open to eligible people ages 0-20

    The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider.

  • Pulmonary Hypertension Association Registry

    open to all eligible people

    The PHA Registry (PHAR) is a national study about people who have pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). PHAR collects information from people with PAH and CTEPH who are cared for in participating PHA-accredited Pulmonary Hypertension Care Centers throughout the U.S. PHAR will determine how people with PAH and CTEPH are evaluated, tested, and treated, and will observe how well these participants do. The goal is to see if people with PH are treated according to recommended guidelines, and to see if there are certain factors that can lead to better or worse outcomes. PHAR will include information about people with PAH and CTEPH in the U.S. who are seen at participating PHA-accredited PH Care Centers. PHAR contains data about patient care and outcomes. Specifically, data in the PHAR includes information on diagnosis; clinical status; socioeconomic status; diagnosis test results; body size; treatment information; interest in participating in clinical trials; family health and social history; and information about smoking, alcohol, or drug use. Participants are followed over time, and provide updates such as changes in therapy, how often participants need to go to the hospital, and survival. Such information may help healthcare providers provide better care.
