The purpose of the study is to evaluate the safety and how well the medication sotatercept works versus placebo in treating Heart Failure with a Preserved Ejection Fraction. The study will also look at information obtained from the tests performed as part of the study to see if subjects have improvement in symptoms of heart failure. Participation in this study will last approximately 26 months. During the study period subjects will be asked to attend regular study visits with the research coordinator. These visits will include such activities as blood tests, questionnaires, physical evaluation by a study doctor, a right heart catheterization with exercise, echocardiogram, and 6 minute hall walks. There will be 35 visits as part of participation in this clinical trial.

Participants will be randomized to either the treatment group (and receive the medication) or the control group (and not receive the medication). Subjects will have a 2:1 chance of receiving the study medication during their participation in the trial. The treatment assignment is determined by randomization, where a computer selects at random which treatment group you will be in (like drawing straws). Neither the subject, nor the blinded personnel will know which group subjects are in. Neither the subject nor the study doctor will decide what group subjects are assigned. Participants from the placebo group in CADENCE who enter HARMONIZE at Visit 9a will be randomized 1:1 to one of the active treatment groups. Participants from an active treatment group in CADENCE entering HARMONIZE after Visit 9a will be allocated to continue in the same treatment group (ie, sotatercept dose level) as in CADENCE.

This is a multicenter, open-label extension (OLE) study to see how safe and effective an inhaled medication called seralutinib is for people with Pulmonary Arterial Hypertension (PAH). The primary objective of this study was to assess improvement in cardiopulmonary hemodynamics as measured by change in pulmonary vascular resistance (PVR) from baseline to Week 24. The secondary objective of this study was to assess improvement in exercise capacity as measured by change in six-minute walk distance (6MWD) from baseline to Week 24.

This study is investigating the drug, called mosliciguat, for the treatment of PH-ILD. Participation in the study may last for about 4 ½ years, although the actual time of participation may be shorter or longer. Part 1 of the study will take about 6 months. Part 2 of the study could last up to about 4 years. During the study, participants will be required to make clinic visits in person and at times will need to meet with study staff over the phone/video. At some of the clinic visits, participants will have blood drawn and have procedures to test their lungs and heart function. Participants will be randomly assigned to get mosliciguat or placebo in Part 1. In Part 2, all participants will get mosliciguat. Approximately 120 people will participate in this study.

Study LTI-401 is an open-label, multicenter study which will evaluate the safety and tolerability of LIQ861, the study drug, in subjects who have World Health Organization (WHO) Group 1 & 3 Pulmonary Hypertension. The purpose of this research study is to evaluate the long-term safety and tolerability of LIQ861 in patients with WHO Group 3 Pulmonary Hypertension associated with interstitial lung disease (PH-ILD). The investigational form of Treprostinil in this study is called LIQ861, it is delivered to your lungs using a hand-held device called a dry powder inhaler (DPI). Dose levels may be adjusted by the Study Doctor between 26.5 micrograms to 318 micrograms based on your PH-ILD symptoms. The study will include approximately 60 subjects and participation will last 52 weeks.

This study is for patients who have heart failure with pulmonary hypertension. Heart failure means that the heart cannot pump blood as well as normal. Pulmonary hypertension happens when the pressure in the blood vessels leading from the heart to the lungs is too high, blood flowing through the lungs is limited, and the pressure in the lungs increases when you are physically active, causing symptoms of shortness of breath and tiredness.

The study uses the Gradient device to see if can help treat heart failure with pulmonary hypertension. This device and therapy is still investigational, which means it is currently not approved by a regulatory agency (such as U.S Food and Drug Administration) for regular hospital use and it includes only individuals who choose to take part. Risks in this study include those for standard cardiac catheterization techniques and the administration of anesthesia including allergic reactions, low blood pressure, skin rash, or difficulty breathing; however, all of the risks may not be known. The study will last approximately 3 years and includes the following visits: Baseline/Screening, Procedure, Discharge, 1 month, 6 months and visits annually for 3 years. Study related procedures include a physical exam, blood testing, 6 minute walk test, echocardiogram, CT scan and a Right heart catheterization.

This is a Phase 2, double-blind, randomized, placebo-controlled study of KER-012 (study drug) compared to Placebo in adult participants with a primary diagnosis of Pulmonary Arterial Hypertension (PAH) on stable background PAH therapy. About 90 participants, in approximately 60 study centers worldwide, will take part in this study. Participation in this study may last up to 2 years and the study has a Screening period, Treatment period, Extension period, and Follow-up period.

This Phase 3 study, comprising a double-blind, placebo-controlled treatment period of up to 48 weeks, will assess the efficacy and safety of seralutinib versus placebo when added to background PAH disease-specific medication in adult PAH subjects who are WHO FC II or III. The primary objective of the study is to assess the efficacy of seralutinib relative to placebo with a primary endpoint of change from baseline to Week 24 in 6MWD.

This clinical investigation is a prospective, non-randomized, single-arm, multi-center early feasibility study of the Aria CV Pulmonary Hypertension (PH) System implanted in patients with pulmonary arterial hypertension (PAH). The device will be implanted in the pulmonary artery and the gas reservoir of the device will be in the abdominal cavity. The purpose of this study is to validate that the clinical use of the Aria CV PH System is safe for the patient, and to evaluate its performance in treating patients with PAH. Some procedures involved in the study include but not limited too: Questionnaires, physical exams, right heart catherization, echocardiograms, blood work and more. The study will be conducted in a maximum of 10 centers in the United States. Up to 45 patients will be consented, and up to 15 patients will receive implants. There is a total of 11 visits over the course of 2.5 years for the study. Because this is an investigational device under the FDA, there may be risk that include but are not limited to: arrhythmia, device infection, endocarditis, and heart failure. If the Aria CV device performs as intended, you may potentially benefit from reduction in or relief of symptoms caused by PH, and depending on your overall health conditions, prolonged life expectancy and/or improvement in your overall quality of life.

This is a phase 4, prospective, multicenter, single-arm, open-label study designed
to evaluate the effect of early and rapid treprostinil therapy on mean pulmonary artery pressure (mPAP) reduction to improve Right ventricular (RV) function and reverse RV remodeling in patients with PAH. This study will use the CardioMEMS™ HF System (CardioMEMS) to measure and monitor mPAP, but may allow mPAP monitoring via RHC (right heart catheterization), if CardioMEMS is NOT available at a subject's Baseline Visit (Day 1) or if the CardioMEMS™ PA Sensor implantation is unsuccessful.

Participation is expected to be up to 37 months and will include about 10 office visits to the study doctor. This will be divided up into a 30-day Screening Period, a 12-month Treatment Period, and a 24-month Extended Treatment Period.

Subjects will have a 66:33 chance of receiving the study medication during their participation in the trial. The treatment assignment is determined by randomization, where a computer selects at random which treatment group you will be in (like drawing straws). Neither the subject, nor the blinded personnel will know which group subjects are in. Neither the subject nor the study doctor will decide what group subjects are assigned.
