Active clinical trials for "Hypertension, Pulmonary"

This local, prospective, non-interventional, multi-center study includes patients treated with Riociguat for inoperable CTEPH(Chronic thromboembolic pulmonary hypertension)/ persistent or recurrent CTEPH after surgical treatment. It is planned to include a total of 400 patients (valid for safety analysis). This study is performed as an all-case investigation. The treatment of Riociguat is performed based on the product label in Japan. The standard observation period is 12 months from the 1st treatment of Riociguat. Safety and effectiveness are evaluated at 4th and 12th month. In addition, the extension observation is carried out once a year for 7 years at the longest to collect information on safety and effectiveness as long as Riociguat treatment continues. When the treatment of Riociguat is terminated, observation of a patient ends. For each patient, the investigator records data as defined in the protocol at each evaluation point by using the Electronic Data Capture (EDC) system. The duration of the study is approximately 9 years from launch.

This is an open label, long term extension to Study AMB115811. All subjects may remain in the extension study for a minimum of 18 months. Beyond the 18-month period, subjects may continue in the extension study until one of the following: the product is approved locally for use in inoperable CTEPH patients; development for use in the CTEPH population is discontinued or product is not approved by the local regulatory authorities; or the investigator decides to discontinue the subject or subject decides to discontinue from the study. The primary purpose of this study is to provide clinically relevant information on the long term safety of ambrisentan in subjects with inoperable CTEPH.

This study is a multi-center, prospective, randomized, double blind, placebo-controlled clinical trial. Subjects in the study will be adults with New York Heart Association (NYHA) Class II-IV heart failure (HF) due to left ventricular systolic dysfunction (LVSD), left ventricular ejection fraction (LVEF) <0.40, and secondary pulmonary hypertension (PH). The purpose of the study is to evaluate the safety, effectiveness, and effects of tadalafil compared to placebo on the subjects' functional capacity / quality of life.

To evaluate the efficacy and safety of 26-weeks of treatment with riociguat vs. placebo in patients with symptomatic PH (pulmonary hypertension) associated with IIP (idiopathic interstitial pneumonias).

A Comparison of Safety and Inhalation Times of Ventavis (iloprost) Inhalation Solution delivered by I-Neb Utilizing Power Disc-6 and Power Disc-15 "Power 15 Study"

Inhaled Iloprost will be administered to near term infants with Persistent Pulmonary Hypertension of the Newborn in two different doses in order to test safety and efficacy in reducing pulmonary artery pressure.

The purpose of this 8-week study is to compare the effects of switching from therapy with epoprostenol or Flolan to IV Remodulin. This study will also assess the effect that changing to Remodulin will have on patient satisfaction with their treatment and impact on quality of life.

To diagnose pulmonary hypertension, children have a cardiac catheterization to check the blood pressure in their lungs. Children with pulmonary hypertension have high blood pressure in their lungs. The right ventricle of the heart has to do more work to pump against this higher pressure. The investigators do not know the best medicine(s) to help children with pulmonary hypertension when their right ventricles fail. The purpose of the study is to look at the effects of two different medicines on the blood pressure in the lungs of a child with pulmonary hypertension. The investigators hope to then be able to choose the best medicine for children with pulmonary hypertension and right ventricular failure. The first medicine is called vasopressin. It is a hormone that your body makes on its own. The investigators will be giving it through an intravenous infusion. The investigators think that vasopressin works differently in different parts of your body. The investigators are looking to see the different effects that vasopressin has in the lungs compared to the rest of the body. The second medicine is called prostacyclin and is something that your body also makes by itself. Prostacyclin, given via an intravenous infusion, is a treatment for pulmonary hypertension as it decreases pressure in the blood vessels. In the catheterization laboratory, patients breathe in this medicine to measure specific changes in the blood pressure in their lungs.

The goal of this study is to test the hypothesis that hydroxyurea is effective for the specific treatment of secondary pulmonary hypertension found on screening in children and young adults with sickle cell disease.

The purpose of this pilot study is to determine a safe dose of milrinone to use in a larger study of babies with persistent pulmonary hypertension of the newborn (PPHN).
