NCT ID: NCT05247528 Completed - Clinical trials for Resistant Hypertension

Safety And Tolerability Of Subcutaneous MANP In Difficult To Control/Resistant Hypertensive Subjects

DTC/RHS
Start date: December 20, 2021
Phase: Phase 1
Study type: Interventional

A randomized, double-blind, placebo-controlled multiple ascending dose study in hypertensive subjects on stable doses of at least three hypertensive drugs for at least 6 weeks prior to Screening. The study will consist of screening, PK-unit admittance, and safety follow up periods. Subjects will be randomized at a 6:2 ratio of either MANP or placebo and will be stratified by race in each dosage cohort. The entire first Cohort will be given the lowest dosage with subsequent cohorts progressing sequentially to the higher doses depending on safety and tolerability of the previous cohort. Endpoints not related to the safety reviews will be analyzed after the last patient last visit (LPLV).

NCT ID: NCT05087940 Completed - Clinical trials for Resistant Hypertension

Treatment of Resistant Hypertension: Cohort Study

TRYCORT
Start date: June 1, 2021
Phase:
Study type: Observational

This is a multicenter, prospective observational cohort study. It will compare effectiveness and safety of various add-on treatment options in regard to arterial blood pressure control in adult patients with treatment resistant hypertension: an aldosterone receptor blocker (e.g. spironolactone), a loop diuretic, a thiazide in large daily dose, an alpha 1 selective blocker or a beta 1 selective blocker. The add-on therapy will be prescribed to the patients within the scope of their routine medical care, independently from the study investigators. The patients will be followed up for 6 months, with monthly visits and continuous home blood pressure diary kept by the patients themselves.

NCT ID: NCT04519658 Completed - Clinical trials for Resistant Hypertension

BrigHTN
Start date: October 12, 2020
Phase: Phase 2
Study type: Interventional

This is a randomized, double-blind, placebo-controlled, dose-ranging Phase 2 study to evaluate the efficacy and safety of CIN-107 as compared to placebo after 12 weeks of treatment in patients with treatment-resistant hypertension (rHTN).

NCT ID: NCT04345198 Completed - Clinical trials for Resistant Hypertension

Adrenal Artery Ablation for Primary Aldosteronism With Resistant Hypertension

Start date: October 1, 2017
Phase: N/A
Study type: Interventional

Primary aldosteronism(PA) is the most common endocrine cause of resistant hypertension. Surgery and medicine are the main treatment for PA by the current guidelines. However,only a small part of patients with PA meet the surgical criteria, and most of them have to take spironolactone or other antihypertensive drugs for long time. On the other side, long-term inhibition of aldosterone receptor may cause hyperkalemia, male breast hyperplasia and other adverse reactions. Moreover, hyperaldosterone is still not corrected by spironolactone, which cause extensive cerebrovascular damages even though blood pressure and blood potassium had been normalized. With the development of adrenal vein sampling and adrenal ablation, the precise diagnosis and treatment of PA is possible. Selective adrenal artery ablation (AAA) was observed with significant decrease of blood aldosterone and blood pressure in patients with PA, which made it promissing that primary aldosteronism with resistant hypertension could be relieved by adrenal artery ablation.

NCT ID: NCT03541174 Completed - Clinical trials for Resistant Hypertension

A Research Study to Show the Effect of Aprocitentan in the Treatment of Difficult to Control (Resistant) High Blood Pressure (Hypertension) and Find Out More About Its Safety

PRECISION
Start date: June 18, 2018
Phase: Phase 3
Study type: Interventional

The goal of this clinical trial is to show the blood pressure lowering effect of aprocitentan, a new drug, when added to other anti-hypertensive drugs of patients with difficult to control (resistant) high blood pressure (hypertension), and to show that blood pressure reduction is kept for long period of time.

NCT ID: NCT03090529 Completed - Clinical trials for Resistant Hypertension

The Role of Exercise Training in the Treatment of Resistant Hypertension

EnRIcH
Start date: March 30, 2017
Phase: N/A
Study type: Interventional

The main purpose of this study is to assess whether exercise training reduces ambulatory blood pressure in patients with resistant hypertension. To accomplish these goals 60 patients with resistant hypertension will be recruited and randomized into exercise training or control groups and followed up for 6 months. The patients in the exercise group will participate in a 3-month outpatient program. The control group will receive usual medical care. At baseline, after the intervention and 3 months after the end of the intervention both groups will undergo several evaluations, including casual and ambulatory blood pressure, body composition, cardiorespiratory fitness, quality of life, arterial stiffness, autonomic function, and endothelial and inflammatory biomarkers.

NCT ID: NCT03071263 Completed - Hyperkalemia Clinical Trials

Spironolactone With Patiromer in the Treatment of Resistant Hypertension in Chronic Kidney Disease

AMBER
Start date: January 23, 2017
Phase: Phase 2
Study type: Interventional

The purpose of this study is to determine if patiromer treatment in chronic kidney disease (CKD) subjects receiving spironolactone for the treatment of resistant hypertension will result in more persistent use of spironolactone through prevention of hyperkalemia and lead to improved blood pressure control compared with treatment with spironolactone alone (placebo).

NCT ID: NCT02572024 Completed - Clinical trials for Resistant Hypertension

The Effect of BATon BP and Sympathetic Function in Resistant Hypertension (The Nordic BAT Study)

BAT
Start date: November 2015
Phase: N/A
Study type: Interventional

Resistant hypertension (RH) affects some 10% to 15% of all patients with hypertension. These patients are at a clearly increased risk for end organ damage and mortality. Furthermore, arterial hypertension is a multifactorial disease including genetic, lifestyle, dietary, metabolic, and sympathetic factors. However, the current treatment modalities have not been optimal in targeting the compensatory changes in sympathetic nervous system function and new strategies have been warranted. Baroreflex activation therapy (BAT) is a special treatment option for some patients with RH that modulates the autonomic nervous system to restore sympathovagal balance. Notably, in BAT both long-term safety and efficacy in a large-scale, randomized, double blind, controlled trial has been shown. However, the trial design and BAT methodology resulted in that the first generation Rheos® system did not achieve the prespecified endpoints for short-term safety and efficacy. Notably, a second-generation minimally invasive BAT system (Barostim Neo®) has now been developed to address these limitations although randomized, double blind, controlled clinical trials are still lacking. Noteworthy, in the recent European Society of Hypertension/European Society of Cardiology (ESH/ESC) Guidelines for the management of arterial hypertension, carotid baroreceptor stimulation is mentioned as one of the options to treat resistant hypertension. Based on these data the aim of this randomized, double-blind, parallel-design clinical trial is to examine the effect of BAT compared to continuous pharmacotherapy on blood pressure, as well as arterial and cardiac function and structure using non-invasive high technology methodology, in a Nordic multicentre study. This study will include 100 patients with RH (20 from Helsinki). Eligible patients are between 18 and 70 years and have a daytime systolic ambulatory blood pressure 145 mmHg or more, and/or a daytime diastolic ambulatory blood pressure of 95 mmHg or more, after witnessed intake of antihypertensive treatment (including at least 3 antihypertensive drugs preferably including a diuretic), with no changes in medication for a minimum of 4 weeks prior to enrolment. Patients with severe renal insufficiency, type 1 diabetes, psychiatric illness, severe cardiovascular disease, or any complication that is a risk to the planned surgery are exclusion criteria. The primary end point is to test whether BAT reduces 24-hour systolic ambulatory blood pressure at 8 months of follow-up compared to continuous pharmacotherapy. Secondary end points are to test whether BAT reduces home blood pressure during follow-up compared to continuous pharmacotherapy, whether BAT reduces office blood pressure during follow-up compared to continuous pharmacotherapy, and the effect of BAT on autonomic function measured as eg. baroreflex sensitivity and heart rate variability.

NCT ID: NCT02001350 Completed - Clinical trials for Resistant Hypertension

Carotid Ultrasound Study

Start date: November 2013
Phase: N/A
Study type: Observational

To use carotid ultrasound to screen 20-30 patients with longstanding or resistant hypertension for carotid atherosclerotic disease and bifurcation anatomy. This will establish a screening protocol for Cibiem's eventual endovascular carotid body modulation trial and will give insight into the prevalence and specific location of carotid plaque at the bifurcation in this patient population.

NCT ID: NCT01897727 Completed - Clinical trials for Obstructive Sleep Apnea

Etiology of Sleep Apnea-related Hyperaldosteronism - BP Treatment

Start date: January 2009
Phase: N/A
Study type: Interventional

Hypertension affects an estimated 60-70 million Americans, predisposing them to potentially life threatening cardiovascular complications. Resistant hypertension, defined as uncontrolled blood pressure on 3 or more different antihypertensive agents, is common, affecting 15-20% of the entire hypertensive population or an estimated 12-14 million Americans. Although associated with obesity, increasing age, black race, and chronic kidney disease, mechanisms of treatment resistance remain obscure. The investigators' laboratory identified primary aldosteronism (PA) as a common cause of treatment resistance with a prevalence of 20% among subjects with resistant hypertension. This is clinically important because recognition of PA can lead to effective treatment with use of aldosterone blockers. Obstructive sleep apnea (OSA) is strongly associated with and predicts development of hypertension as demonstrated in landmark cohort studies including the Sleep Heart Health Study and the Wisconsin Sleep Cohort Study. The investigators' laboratory has confirmed OSA to be extremely common in subjects with resistant hypertension, with a prevalence of approximately 85%. Recognizing that PA and OSA are exceptionally common in subjects with resistant hypertension, the investigators hypothesized that the 2 may be causally related. In testing this hypothesis, the investigators recently reported that plasma aldosterone levels are positively correlated with OSA severity in subjects with resistant hypertension but not in normotensive control subjects. This observation suggests that there is an important mechanistic interaction between untreated OSA and aldosterone excess in subjects with resistant hypertension. While the investigators' original hypothesis was that OSA stimulates aldosterone release, the investigators recognize that the opposite may also be true; that is, aldosterone excess in subjects with resistant hypertension worsens OSA. Distinguishing between these two possibilities has potentially far-reaching clinical implications. If the former hypothesis is true, effective treatment of OSA would be expected to suppress aldosterone release in subjects with resistant hypertension, thereby reversing the underlying cause of their treatment resistance. If the latter hypothesis is true, use of mineralocorticoid receptor antagonists would be expected to reduce OSA severity in subjects with resistant hypertension, thereby enhancing treatment of OSA. Either scenario would represent a new treatment approach for a highly prevalent and serious medical problem.
