NCT02462967
Study GT 026 is a Phase 2, multicenter, parallel group, North American, randomized, placebo controlled, double blind study. This study will enroll subjects with portal hypertension (HVPG greater than or equal to 6 mm Hg) who also have a liver biopsy with cirrhosis (Ishak stage 5 or 6), presumably due to NASH, excluding subjects with medium and large varices and those with decompensated cirrhosis. Subjects with portal hypertension and cirrhosis will be randomly assigned (1:1:1 ratio) to receive 1 of 3 treatment assignments including placebo, GR MD 02 in a dose of 2 mg/kg lean body mass, or GR MD 02 in a dose of 8 mg/kg lean body mass administered every other week over a 52 week period for a total of 26 intravenous infusions. The primary endpoint analysis is the baseline adjusted change in HVPG at 1 year (53 55 weeks) in subjects treated with placebo as compared to subjects treated with GR MD 02 (2 mg/kg/week or 8 mg/kg/week). An esophagogastroduodenoscopy (EGD) with evaluation for varices, HVPG, and liver biopsy will be performed before the first infusion and after the final 26th dose of the investigational medicinal product (IMP). Additionally, subjects will undergo a FibroScan (if available) prior to the first infusion, at Infusion Visit 13, and 14 to 28 days following final 26th infusion, an methacetin breath test (MBT), will be performed if available at screening, at Infusion Visit 13, and 14 to 28 days after the final infusion, and blood will be collected for assessment of biomarkers. All subjects are to attend 2 postdose visits: the first will occur 14 to 28 days after the final dose administration and a second will occur 14 days following the first postdose visit. Subjects will be offered enrollment into a subsequent separate study, an open label extension study, if there is adequate tolerability and no safety issues or signs of clinical progression that would recommend discontinuation. Subjects who do not enroll in the open label extension study will be contacted via telephone every 6 months for 2 years and annually thereafter for a total of 4 years.

NCT03228082
RATIONALE: Women with a previous history of preeclampsia (PE)/HELLP have a twofold higher risk of cardiovascular disease (CVD) and a fourfold increased risk to develop hypertension at a relative young age. In the latest 2016 ESC guidelines 'CVD prevention', previous PE has been acknowledged as a serious CVD risk factor in women. In clinical practice, however, these women are still underappreciated for their CVD risk. It has not been established yet how adequate lifelong prevention in these potentially high risk women can optimally be achieved from their childbearing years onwards. OBJECTIVE: To evaluate feasibility, usability, acceptance and potential obstacles of blood pressure (BP) home monitoring in high-risk women, aged 40-60 years, after a previous PE in pregnancy. In addition to evaluate the effectiveness of BP home monitoring on the occurrence of hypertension, the efficacy of BP treatment, quality of life (QOL), health-related symptoms, work ability and life-style behaviour. STUDY DESIGN: Randomized, open label feasibility study to compare eHealth guided self management of BP monitoring and lifestyle advice with 'usual care'. STUDY POPULATION: Approximately 200 women, aged ≥ 40 and ≤ 60 years, with a previous PE in pregnancy will be invited to participate (both early and late PE). Patients will be recruited from the departments of obstetrics/gynaecology in 6 centres in the Euregio Rhein-Waal and from the department of cardiology Radboudumc. INTERVENTION: eHealth guided measurements of BP at regular intervals and recurrent lifestyle advice (intervention-group) will be compared with "usual care". PRIMARY OUTCOME: Feasibility, usability, acceptance and potential obstacles of BP home monitoring in high-risk women after a previous PE in pregnancy at 1 year of follow-up.

NCT01564719
This study seeks to test a two-year intervention designed for United Methodist clergy. The intervention consists of: the stress reduction program Williams LifeSkills, adapted for clergy; the 10-session online weight loss program Naturally Slim Foundations plus its 7-session online booster program, Naturally Slim Advanced; monthly phone conversations with Wellness Advocates who function as health coaches; and three in-person workshops that cover the theology of the body and incarnation and provide the religious rationale for caring for the mind and body. Participants were randomly assigned to one of three cohorts, all of which will eventually receive the intervention but which differ by intervention timing, thereby building in a randomized waitlist control group. The investigators hypothesize that intervention participants will achieve reductions in metabolic syndrome, depression, and stress, and achieve improvements in quality of life and spiritual well-being, compared to the waiting control group participants.

NCT04429477
Several recent studies point to the possibility of the new coronavirus (SARS-Cov2), which currently causes pandemic COVID-19, to infiltrate the central nervous system (CNS) and cause primary damage to neural tissues, increasing the morbidity and mortality of these patients. A pathophysiological hypothesis for insulting the CNS would be the impairment of cerebral compliance (CC), because elevation of intracranial pressure (ICP), but due to the invasive nature of the methods available for ICP evaluation, this hypothesis has so far not been verified. Recently, a noninvasive technique was developed to evaluate CC (B4C sensor), making it possible to analyse CC in patients outside the neurosurgical environment. Therefore, the main objective of this study was to assess the presence of CC impairment in patients with COVID-19, and observe potential influences of this syndrome on cerebral hemodynamics.
NCT02027012
REDUCE-HTN-China study is a prospective, multi-center, single cohort study for the percutaneous therapeutic treatment of medication-resistant hypertension in China.The primary objective is to assess the efficacy performance of the Vessix™ Renal Denervation System for the treatment of medication resistant hypertension on the basis of the hypothesis that the percutaneous therapeutic renal denervation for the treatment of medication-resistant hypertension using the Vessix™ Renal Denervation System will reduce systolic (SBP) and diastolic blood pressure (DBP) at 6- month compared to baseline as accessed by office-based blood pressure measurements.

NCT03732924
The Hypertension Canada Clinical Practice Guidelines for blood pressure measurement using AOBP recommend against any wait time prior to commencing the measurement. The recent AHA guidelines however call for a 5-minute rest first. In uncontrolled hypertension, AOBP is typically higher than the daytime readings from ambulatory blood pressure monitoring (ABPM), but this is not the case for patients with controlled hypertension.
NCT03106597
The purpose of this study is to evaluate the effect of a third-generation Calcium Channel Blocker (CCB), manidipine, compared with second-generation Calcium Channel Blocker (CCB), amlodipine, on the development of peripheral edema using Direct Segmental Multi-Frequency Bioelectrical Impedance Analysis (DSM-BIA) method in patients with mild to moderate essential hypertension. Investigator expects this study could show more objective evidence of better safety of manidipine compared with amlodipine for peripheral edema.
NCT02508129
Insomnia and hypertension are common health problems that often occur together and influence each other. This practical, low-cost, clinical trial will evaluate two behavioral treatments for insomnia (a brief intervention with therapist contact and a self-guided Internet intervention) compared to usual care. Participants will be recruited using the electronic health record in their primary care physicians' offices, and will be evaluated for sleep, blood pressure, and health outcomes after 9 weeks, 6 months, and 12 months.
NCT04531267
Although the epidemiological studies indicate how magnesium and calcium may interact to affect cardiovascular risk, current clinical trials have not elucidated the associations, particularly among hypertensive patients. To address the research gap, we have to examine how magnesium may influence cardiovascular profile of hypertensive patients via the modification of calcium homeostasis. Meanwhile, large-scale cohorts in China suggested keeping dietary calcium: magnesium ratio within 2.3 can reduce the risk of cardiovascular mortality. The results indicate the potential for individualized nutrition. This study will recruit uncontrolled hypertensive patients taking single drug and investigate whether calcium-magnesium combined supplements help to control their blood pressure. In standardized manner, subjects in the intervention group and the control group (each with 21 subjects) will be assessed for their dietary calcium and magnesium intake in the previous three months, so that researchers can provide calcium and/or magnesium supplements to maintain a calcium/magnesium ratio as 2.3. The effect of supplementation will be evaluated by the blood pressure changes in the 12th week of intervention.

NCT03251872
The main OBJECTIVE of this proposal is to extend our preclinical findings on the role of DNA damage and poly(ADP-ribose) polymerases (PARP) inhibition as a therapy for a devastating disease, pulmonary arterial hypertension (PAH), to early-phase clinical trials. We, and others, have published strong evidence that DNA damage accounts for disease progression in PAH and showed that PARP1 inhibition can reverse PAH in several animal models1. Interestingly, PARP1 inhibition is also cardioprotective. Olaparib, an orally available PARP1 inhibitor, can reverse cancer growth in animals and humans with a good safety profile, and is now approved for the treatment of ovarian cancer in Canada, Europe and the USA. The time is thus right to translate our findings in human PAH. The industry-sponsored clinical research on PARP1 inhibitor is currently entirely cancer-oriented. Nonetheless, AstraZeneca Canada accepted to support an early phase clinical trial through in-kind contribution, but the support from foundations and federal agencies is critical to catalyze early-stage development of PARP1 inhibitors for other indications, especially for orphan diseases. A CIHR Project Scheme grant will thus be submitted on September 15 2017, proposing a Phase 1, followed by a Phase 2 trial that will be conducted in recognized PAH programs throughout Canada. At this stage, however, we propose a pilot study to assess the feasibility of the proposed trials in the PAH population. The overall HYPOTHESIS is that PARP1 inhibition with olaparib is a safe and effective therapy for PAH. The primary objective of the study is to confirm feasibility, to support the safety of using olaparib in PAH patients, and precise the sample size of the coming Phase 1B trial. The feasibility of the comprehensive patient phenotyping that will be proposed within the phase 1B trial will thus be assessed, in addition to adverse events and efficacy signals. \*\*\*OPTION pilot trial was merged with the new OPTION multicenter trial (NCT03782818)\*\*\*
NCT00980785
Angiotensin converting enzyme inhibitors (ACE-I) are a group of blood pressure-lowering medicines. Some studies suggest that ACE-I, such as ramipril, may help prevent Alzheimer's disease (AD). The purpose of the research is to see how ramipril affects a substance in the body called beta-amyloid. Beta-amyloid is found in the brain and in the liquid around the brain and spinal cord. High amounts of beta-amyloid may be associated with a greater risk of getting Alzheimer's disease. This study will see if ramipril can lower the amount of beta-amyloid in the spinal fluid. This study will also see if ramipril affects blood vessel function and memory and thinking. The investigators hope that future studies will show whether ramipril might prevent memory loss and decrease the chance of developing Alzheimer's disease.
