High blood pressure clinical trials in Houston

The purpose of this study is to assess the efficacy and safety of the study drug, levosimendan (given orally), compared to placebo in participants with pulmonary hypertension with heart failure with preserved left ventricular ejection fraction (PH-HFpEF) as measured by the change in 6-Minute Walk Distance.

The purpose of this study is to determine if de-implementation of inhaled nitric oxide (iNO) in the post-natal resuscitation/stabilization phase affects the composite outcome of extracorporeal life support (ECLS) use and/or mortality, as well as ECLS use, mortality, and/or oxygenation in congenital diaphragmatic hernia (CDH) newborns and to establish the cost-effectiveness of de-implementing iNO as a therapy in the postnatal resuscitation/stabilization phase of CDH management, which will be assessed as the incremental health system costs (savings) per prevented ECLS use and/or death.

Women pregnant between 11-14 weeks gestation will be enrolled with blood samples collected to evaluate for preeclampsia.

The purpose of this study is to evaluate whether zilebesiran versus placebo reduces the risk of cardiovascular (CV) death, nonfatal myocardial infarction (MI), nonfatal stroke, or heart failure (HF) events. This is an event-driven study that will continue until the targeted number of positively adjudicated primary endpoint clinical outcome events (COEs) have been reached.

This study is open to adults with type 2 diabetes, high blood pressure, and cardiovascular disease. People can join the study if they have these conditions and do not have a history of heart failure. The purpose of this study is to find out if a medicine called vicadrostat, when taken with empagliflozin, helps reduce cardiovascular risk in people with these conditions. The study will compare this combination to a placebo version of vicadrostat with empagliflozin. Participants are put into 2 groups randomly, which means by chance. One group takes vicadrostat and empagliflozin tablets, and the other group takes placebo tablets with empagliflozin. Placebo tablets look like vicadrostat tablets but do not contain any medicine. Participants take a tablet once per day for 2 and a half years and up to 4 years and 3 months. All participants also continue their medication for type 2 diabetes, high blood pressure, and cardiovascular disease. Participants have an equal chance of receiving the study medicine or placebo. Participants are in the study for up to 4 years and 3 months. During this time, they visit the study site regularly. During these visits, doctors collect information about participants' health and take blood samples. The doctors document when participants experience cardiovascular events. The doctors also regularly check participants' health and take note of any unwanted effects.

This trial is a randomized study to evaluate the Bimatoprost Implant System used in combination with the SpyGlass IOL to Timolol Ophthalmic Solution in participants with mild to moderate open-angle glaucoma or ocular hypertension undergoing cataract surgery.

A randomized controlled trial of 1,500 women to assess whether treatment of obstructive sleep apnea with continuous positive airway pressure (CPAP) in pregnancy will result in a reduction in the rate of hypertensive disorders of pregnancy.

A prospective, multinational, randomized, double-blind, clinical trial evaluating the safety and effectiveness of a novel atrioventricular interval modulation (AVIM) algorithm downloaded into a dual-chamber Medtronic Astra/Azure pacemaker.

This is a Phase 2 dose-titration study designed to evaluate the safety and efficacy of MANP subcutaneous injection compared to placebo in reducing baseline daytime systolic blood pressure (SBP), derived from 24-hour ambulatory blood pressure monitoring (ABPM), in subjects with hypertension who are taking 3 or more antihypertensive medications with different mechanisms of action.

The primary objective of the THRIVE Pivotal study is to demonstrate the adjunctive effectiveness and the safety of the TIVUS system in: 1. subjects with hypertension (HTN) receiving up to 2 anti-hypertensive drugs of different classes in whom the anti-hypertensive medications will be stopped for a 4-week wash-out period before RDN/Sham procedure and during 2 months after procedure. 2. subjects with controlled hypertension receiving up to 2 anti-hypertensive drugs of different classes and who accept to be off-medications for a 4-week wash-out period before RDN/Sham procedure and 2 months after the procedure

Severe traumatic brain injury (TBI) is associated with a 20-30% mortality rate and significant disability among most survivors. The Centers for Disease Control and Prevention (CDC) estimate that 2% of the U.S. population lives with disabilities directly attributable to TBI, with annual costs exceeding $76.5 billion. Current treatments are largely ineffective because they are instituted after irreversible damage has already occurred. By the time intracranial pressure (ICP) increases or brain tissue oxygen tension (PbtO2) decreases to harmful levels, it is often too late to reverse or repair the damage. A computerized method has been developed that can predict these injurious events ahead of time, allowing clinicians to intervene before further damage occurs. The goal of this proposal is to test these predictions in real time. The first phase of the project (Year 1) involves setting up the informatics infrastructure, with no patient interaction. In the second phase (Year 2), subjects, through surrogate decision-makers, will be enrolled in an observational study where data on intracranial pressure and brain tissue oxygen tension will be collected, and the prediction algorithm will be tested for accuracy. Clinical management will follow standard care protocols, and no additional interventions will be performed. Approximately 120 individuals will participate in this study at the University of Chicago and Ben Taub General Hospital in Houston. Data collected will include both the electronic medical record and data from bedside intensive care unit monitors. The electronic medical record includes demographic information, injury characteristics, laboratory values, and imaging data, while the intensive care unit monitor provides real-time vital signs such as intracranial pressure, brain tissue oxygen tension, and mean arterial pressure. These data will be securely stored in a research computer database. Efforts will be made to contact subjects or their caretakers at 6 months to follow up on recovery. This research aims to improve patient outcomes by providing predictions of further brain injury, with the potential for future interventions to prevent permanent brain damage.

The proposed study, "Check, Monitor, Control Hypertension in Older African American Adults," is a randomized clinical trial designed to improve blood pressure control among African American adults aged 55 years and older in the Greater Houston area. Hypertension disproportionately affects African Americans, contributing to higher rates of cardiovascular disease and stroke. This project aims to improve clinical and behavioral outcomes through a 24-month intervention combining pharmacist-led counseling and Community Health Worker (CHW) support.

Phase 2 Study of BL1107 Eye Drops vs. Timolol in Adults with Primary Open Angle Glaucoma or Ocular Hypertension

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.

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.

Study GMS-PH-001 is a multicenter, open-label, non-randomized study to prospectively evaluate screening strategies of pulmonary hypertension (PH) in patients with interstitial lung disease (ILD).

This study seeks to develop the evidence for a sustainable, community-partnered, multi-level health system strategy to improve blood pressure control. Two team-based approaches are being tested: 1) a medical model of remote BP management (RBPM) alone, and 2) RBPM plus a social model with a community health worker (CHW). These 2 strategies are being compared with a standard community screening program with referral to primary care.

Researchers are looking for more ways to treat PAH. In PAH, the blood vessels in the lungs become thick and narrow, which makes it harder for blood to flow. This causes high blood pressure in the lungs and overworks the heart. PAH can make it hard to breathe and be active. Some standard (usual) treatments for PAH can treat symptoms of PAH but do not stop PAH from getting worse. Sotatercept is a study medicine designed to treat PAH. It is a targeted therapy, which is a treatment that works on certain proteins that play a role in causing PAH. This is a long-term follow-up (LTFU) study. People who took part in certain other studies testing sotatercept for PAH may be able to join this study. The goal of this study is to learn about the long-term safety of sotatercept and if people tolerate it when taken with standard PAH treatment over a longer period of time.

Glaucoma is the second most common cause of blindness in the world, second only to cataracts. This study will assess how safe and effective a glaucoma gel stent is when implanted using the ab interno (inside the eye) and ab externo (outside the eye) approach. Adverse events and intraocular pressure will be assessed. XEN63 is an investigational device for the treatment of intraocular pressure (IOP) in patients with glaucoma when both medical and conventional surgical treatments have failed (for US approval) and when medical treatments have failed (for outside US \[OUS\] approval). Participants will be placed in one of two groups called study arms. One group will receive the XEN63 gel stent ab interno (inside the eye) and the other group will receive the XEN63 gel stent ab externo (outside the eye). Approximately 130 participants aged 45 years or older with glaucoma will be enrolled in this study at approximately 32 sites in the United States. Participants will receive XEN63 implanted using either the ab interno approach or the ab externo approach on Day 1 and will be followed for 12 months. Participants will attend regular visits during the study at a hospital or clinic. The safety and effect of the gel stent on your glaucoma will be checked by medical assessments and eye examinations.

The overall goal of this large, pragmatic, comparative effectiveness trial is to test the hypothesis that among at-risk individuals, 162 mg/day aspirin is superior to 81 mg/day in preventing Hypertensive disorders of pregnancy (HDP), and that there are multiple factors associated with adherence with aspirin therapy that will be important to identify to enable optimal implementation of study findings and population-level benefits.
