65 Clinical Trials for Various Conditions
Background: Childhood-onset essential hypertension (COEH) is high blood pressure that develops in children and teens. High blood pressure is a major risk factor for heart disease. COEH is more likely to be caused by changes in genes rather than by factors like stress or diet. Researchers want to learn more about how changes in genes relate to COEH. They hope to use that information to develop better treatments for children with high blood pressure. Objective: This natural history study will look for genes and gene changes that may lead to COEH. Eligibility: People aged 2 years and older with COEH or who had COEH when they were children. Healthy relatives of those with COEH are also needed. Design: Participants will have one clinic visit per year for up to 10 years. All participants will have a physical exam. They will provide samples of blood and urine. At their first visit, they will have a swab (like a Q-tip) rubbed between their gums and cheeks. They may agree to having a skin biopsy; a piece of skin about the size of a pencil eraser will be removed. Affected participants aged 2 to 17 years old will have additional tests: * They will have sensors placed on their skin to look at their blood vessels and see how blood is moving in their bodies. * They will lie or stand while a machine measures the amount of fat and muscle in their bodies. * They will have an ultrasound; a wand will be rubbed against their skin to take pictures of their kidneys. Other things are optional for all participants: * They may have photographs taken of their bodies. * They may have tests of their heart function. * They may have different types of imaging scans.
This integrated assessment consists of two studies, 603A and 603B, to be carried out sequentially in a common study population. Participating subjects informed of the trial design and their consent to participate in both studies were to be obtained in a single consent form. Approximately 680 male or female adult subjects were to be enrolled.
The purpose of this study was to evaluate the safety of RMJH-111b, including how well it is tolerated, and the effect of RMJH-111b on blood pressure in subjects with hypertension. The study also measured the amount of magnesium in the blood and urine before and after RMJH-111b administration to evaluate what the body does to RMJH-111b (pharmacokinetics).
The main objective will be to evaluate the dose-response of ACT-132577 (aprocitentan) on diastolic blood pressure (DBP) in participants with grade 1 or 2 essential hypertension. Secondary objectives will be to evaluate the dose-response of ACT-132577 on: systolic blood pressure (SBP); control and response rate of blood pressure; 24-hour ambulatory blood pressure monitoring (ABPM) and to evaluate the safety and tolerability of a once daily oral regimen of 4 doses of ACT-132577.
Children are increasingly being diagnosed with essential hypertension and the absence of comparative effectiveness research in antihypertensive therapies has contributed to considerable differences in prescribing practices among physicians treating children with essential hypertension. This study will consist of a series of systematically-administered n-of-1 trials among children to verify the need for ongoing antihypertensive treatment and if so, to identify the preferred single drug therapy.
The purpose of this study is to better understand the cardiovascular effects of the vasodilatory peptide Angiotensin (1-7) in human hypertension. In this study, the investigators will test the hypothesis that systemic Angiotensin (1-7) infusion produces negligible effects with intact baroreceptors, and that the cardiovascular effects of this peptide are unmasked following elimination of baroreflex buffering.
This study is an exploratory Phase 1 randomized, double-blind (Investigator and study subject and 2-D echo endpoint assessor), placebo-controlled single IV infusion dose escalation study that will enroll up to approximately 32 subjects with stage 1 or 2 essential hypertension.
This study examines the long term safety and efficacy of the Fixed Dose combination BAY98-7106 (nifedipine plus candesartan primarily at the highest dose in development) in patients with moderate to severe hypertension. Patients meeting the entry criteria, will receive the Fixed Dose combination for 28 weeks, including 8 weeks with stepwise dose increase up to the high target dose. The first 200 subjects completing 28 weeks will continue treatment for additional 24 weeks (52 weeks in total). Subjects who do not tolerate an increased dose will be treated at their highest tolerable dose.
The primary objective of the study is to evaluate the safety and tolerability of single ascending doses of Vasomera (PB1046) administered subcutaneously in adult subjects with Stage 1 or Stage 2 essential hypertension. The secondary objectives of the study are to characterize the pharmacokinetic profile of single ascending doses of Vasomera and the relationship between serum concentrations of Vasomera and change in systolic and diastolic blood pressure as measured by: * Mean change from baseline in 24-hour systolic and diastolic blood pressure measured by ambulatory blood pressure monitoring (ABPM) as compared to placebo. * Identification of the minimum and maximum decrease in systolic and diastolic blood pressure as measured by ABPM. * Mean change from baseline in cuff systolic and diastolic blood pressure as compared to placebo. * Effect of Vasomera on pulse pressure and heart rate. An additional secondary objective of this study will be to characterize the immunogenicity profile of Vasomera following a single subcutaneous dose.
This study will assess the efficacy and safety of LFF269 compared to placebo after treatment in subjects with essential hypertension.
The purpose of this study is to determine the blood pressure lowering responses of various dose combinations of nifedipine GITS and candesartan as compared to treatment with each component on their own (monotherapy) and placebo (a look-alike tablet without active ingredient). The drugs - nifedipine GITS and candesartan - which are being investigated are currently approved for use in patients with essential hypertension alone or together with other antihypertensive drugs (combination therapy), but the optimal dose of nifedipine GITS and candesartan used together in the treatment of essential hypertension has not been established yet. In this study patients will be treated with various doses of nifedipine GITS and/or candesartan or placebo. These different regimens will be administered once a day and will be assessed based on their blood pressure lowering effects (mean sitting diastolic blood pressure) in subjects with mild to moderate essential hypertension.
The goal of this project is to investigate the effects that the addition of aldosterone blockade with eplerenone will have on the progression of diastolic dysfunction in patients with controlled essential hypertension.
