High Blood Pressure clinical trials at UCSD

This study is being conducted to assess the long-term safety, tolerability, and efficacy of sotatercept in participants with Pulmonary Arterial Hypertension (PAH). This open-label, long-term follow-up (LTFU) study is supported by data from the PULSAR study (Phase 2, NCT03496207) in which treatment with sotatercept resulted in hemodynamic and functional improvements in the study participants, including those receiving maximal PAH therapy with double/triple drug combinations and intravenous prostacyclin. The primary objective of this open-label, LTFU study is to evaluate the long-term safety and tolerability of sotatercept when added to background PAH therapy in adult participants with PAH who have completed prior sotatercept studies. The secondary objective is to evaluate continued efficacy in adult participants with PAH who have completed prior sotatercept studies.

Study ROR-PH-303, ADVANCE EXTENSION, is an open-label extension (OLE) study for participants with WHO Group 1 PAH who have participated in another Phase 2 or Phase 3 study of ralinepag.

The purpose of the study is to assess the effects of selexipag on right ventricular (RV) function in participants with Pulmonary arterial hypertension (PAH).

The objective of this study is to evaluate the effects of sotatercept (MK-7962, formerly called ACE-011) treatment (plus maximum tolerated background pulmonary arterial hypertension (PAH) therapy) versus placebo (plus maximum tolerated background PAH therapy) on time to first event of all cause death, lung transplantation, or PAH worsening-related hospitalization of ≥24 hours, in participants with World Health Organization (WHO) functional class (FC) III or FC IV PAH at high risk of mortality.

Over 30% of American adults have hypertension (HTN) (high blood pressure), and the rate increases considerably with age; 64% of men and 78% of women over 65 have HTN. High blood pressure associated with HTN can force of the blood against artery walls with enough pressure that it can eventually cause health problems, such as heart disease and stroke. HTN is one of the most significant causes of early death worldwide and one of the most preventable causes of death. Many studies reveal that lowering blood pressure (BP) reduces the incidence of diseases of the heart and blood vessels. Non-drug related treatments are known to reduce BP which can have a great effect on public health. Research suggests that Tai Chi (TC) is effective in lowering BP in patients with HTN, but because of the low quality of existing studies there is no definite proof. Also, it is not known how TC reduces BP. One possibility is that TC practice, which is shown to reduce psychological distress such as anxiety and depression and reduce the body's responses to stress, can improve the balance of the autonomic nervous system (the part of your nervous system that controls beating of the heart and the widening or narrowing of blood vessels). This may lead to lower BP. The investigators plan to investigate the pathways among autonomic, blood vessel, immune and psychological factors in relation to BP changes in response to 12-weeks of TC compared with Healthy Aging Practice-centered Education (HAP-E). 250 older adults (60+ years old) with mild HTN will be enrolled, and the investigators will take several measurements of heart and nervous system functioning. The investigators hypothesize that performing TC for 12 weeks will result in autonomic "re-regulation" which will improve BP and blood vessel health (Aim 1) and sympathetic nervous system (part of the nervous system that serves to speed up heart rate, contract blood vessels, and raise blood pressure) regulation of the immune system (Aim 2). Lastly, the investigators hypothesize that psychological factors will be related to TC effects on autonomic regulation (Aim 3). Findings from the investigators study will hopefully shed light on the pathways by which TC reduces BP. Also, the particular effects of TC ("meditative movement") in an older, "hard-to-treat" hypertensive population will be better understood.

This study will evaluate the long-term safety and efficacy of Bimatoprost Sustained Release (SR) in patients with open-angle glaucoma or ocular hypertension who completed 1 of the 4 Phase 3 Bimatoprost SR studies (192024-091, -092, -093, or -095) and received Bimatoprost SR or who received commercial DURYSTA (Bimatoprost SR) in the open-label Phase 4 ARGOS study (MED-MA-EYE-0648) and completed (or exited early from) the study.

The objective of this study is to assess the safety, performance and initial effectiveness of the TIVUS™ System when used for pulmonary artery denervation through subjective and objective change in clinical parameters and haemodynamic evaluation. This is a prospective, multi-center, non-randomized, open-label clinical trail. The study will be conducted in up to 4 centers and will recruit up to 15 patients diagnosed with PAH, functional class III who have stable PAH on a stable drug regimen of two pulmonary arterial hypertension specific medications.

The objective of this study is to assess the safety and initial effectiveness of the TIVUS™ System when used for pulmonary artery denervation in group II PH patients through change in clinical parameters including hemodynamics, exercise tolerance, and quality of life. This is a prospective, multi-center, non-randomized, open-label clinical trail. The study will be conducted in up to 3 centers and will recruit up to 15 patients diagnosed with pulmonary hypertension due to left heart disease that demonstrate combined pre and post capillary involvement with PVR>3 wood units.

Potential outcomes after PE occur on a spectrum: complete recovery, exercise intolerance from deconditioning/anxiety, dyspnea from concomitant cardiopulmonary conditions, dyspnea from residual pulmonary vascular occlusion, chronic thromboembolic disease and chronic thromboembolic pulmonary hypertension. Although a battery of advanced diagnostic tests could distinguish each of those conditions, the yield of individual tests among all post- PE patients is low enough that routine testing of all PE patients is not typically performed. Although the various possible post-PE outcomes have enormous implications for patient care, they are rarely distinguished clinically. Perhaps for this reason, chronic conditions after PE are rarely (if ever) used as endpoints in randomized clinical trials of acute PE treatment. The proposed project will validate a clinical decision tree to distinguish among the various discrete outcomes cost-effectively through a hierarchical series of tests with the acronym SEARCH (for symptom screen, exercise function, arterial perfusion, resting heart function, confirmatory imaging and hemodynamics). Each step of the algorithm sorts a subset of patients into a diagnostic category unequivocally in a cost-effective manner. The categories are mutually exclusive and collectively exhaustive, so that each case falls into one, and only one, category. Each individual test used in the algorithm has been clinically validated in pulmonary embolism patients, including the cardiopulmonary exercise test (CPET) technique that the investigators developed and validated. However, the decision tree approach to deploying the tests has not yet been validated. Aim 1 will determine whether the SEARCH algorithm will yield concordant post-PE diagnoses when multiple reviewers independently evaluate multiple cases (reliability). Aim 2 will determine whether the post-PE diagnoses are stable, according to the SEARCH algorithm, between the first evaluation and the subsequent one six months later (validity).
