Active clinical trials for "Hypertension"

This is a clinical study evaluating the superiority in efficacy and assess safety and tolerability of BAYA1040_Nifedipine 80 mg/day (40 mg twice daily) compared with BAYA1040_Nifedipine 40 mg/day (40 mg once daily) in patients with essential hypertension who are not at target blood pressure by BAYA1040_Nifedipine 40 mg once daily treatment.

The purpose of this study is to assess tolerability and clinical effects of transition from intravenous (IV, needle in the vein) or subcutaneous (SQ, needle in the skin) to the recently-approved inhaled treprostinil (Tyvaso) for the treatment of pulmonary arterial hypertension (PAH). Our hypothesis is that the transition to inhaled treprostinil will be tolerated by patients. The intravenous and subcutaneous drugs epoprostenol and treprostinil received approval for treatment of PAH many years ago. While these medications improve exercise capacity and the symptoms of PAH, they are given by injection and thus have several side effects, such as pain and catheter infection. This has resulted in many patients either refusing to take the medication or quitting these medications because of not tolerating them. The only other form of prostacyclin treatment available for PAH patients is inhaled. There are 2 inhaled prostacyclins approved for PAH, however one of these requires at least 6 inhalations per day, every day, and takes about 30 minutes to inhale each time. Thus, it has not been a regularly-used medication and issues surrounding compliance make it a riskier drug to use if patients do not get their full doses every day. The other inhaled medication, treprostinil, was approved a few months ago, only needs to be given 4 times a day, and takes about 2-3 minutes to inhale. Since inhaled treprostinil can be administered easily, it is anticipated that many patients will transition from epoprostenol or treprostinil to the recently approved inhaled treprostinil, however we do not know if this is a safe or effective way to manage patients. Thus, the goal of this prospective study is to gather observational data regarding how that switch is made, tolerability of the switch, and, to the extent possible with this methodology, assess clinical effects of the switch. This is a prospective study. Twenty patients > 18 years old with PAH will be enrolled. Patients enrolled will be those in whom a clinical decision to convert from either IV epoprostenol, IV treprostinil, or SQ treprostinil to inhaled treprostinil therapy has been made. This is usually the result of patients asking to switch to inhaled therapy, but only allowed by physicians if they feel the switch would be safe. If eligible, and after informed consent, patients will have a history and physical examination, a 6 min walk test, a cardiopulmonary exercise test (CPET), blood tests, and a symptom questionnaire will be filled out. Patients will then be admitted to the hospital where a monitoring catheter will be placed inside the patient's heart and inhaled treprostinil will be initiated, while the dose of IV/SQ medication is reduced over about 24-26 hours. Clinical follow-up will be at weeks 1, 4, and 12. The procedures above are all part of the routine clinical care that patients would receive if they were to be transitioned to inhaled therapy, including the hospitalization and catheterization. The criteria for them to be able to be switched are conservative. Pressure in their heart and lungs must be low (mPAP < 40 mmHg and RAP <12 mmHg on catheterization), and their dose of IV or SQ medication must be low (< 20 ng/kg/min). Regarding the patient subset enrolled in this study in whom a clinical decision to convert transition therapy has been made, we will try to ensure that our clinical decision-making will not be influenced by the need to enroll subjects in the study by explicitly noting the potential for conflict of interest with each patient (addressed in the ICF). We will not make a clinical decision for our patients based on the desire to fill the study numbers, and every will be made to avoid the potential for a perceived conflict of interest.

DHEA prevents and reverses chronic hypoxic pulmonary hypertension in a chronic hypoxic-pulmonary hypertension model in the rat. However, no study has been performed in human. The purpose of this study is to determine if DHEA is effective in the treatment of respiratory pulmonary hypertension in adults with Chronic Obstructive Pulmonary Disease (COPD) on exercise capacity and haemodynamic variables. Patients will receive after randomisation either 25 mg/day or 200mg/day oral DHEA over a one-year period. Evaluation concerns clinical parameters, echocardiography and right catheterization after and before treatment. Primary end-point is the six-minute walk test. This is a prospective double blind, randomised, placebo controlled study which will be realized in four university hospitals in France : Bordeaux, Strasbourg, Toulouse and Limoges.

This study will evaluate the tolerability and safety of SAD448 and explore the compound's effect on intraocular pressure in subjects with ocular hypertension.

To assess the long-term (6 month and 12 month) safety of the combination of aliskiren 300 mg / amlodipine 10 mg in patients with essential hypertension (Mean Sitting Diastolic Blood Pressure [msDBP] ≥ 90 mmHg and < 110 mmHg).

The aim is to compare the blood pressure lowering effect of the combination of candesartan cilexetil (candesartan) 32 mg and hydrochlorothiazide (HCT) 25 mg to that of candesartan 32 mg alone, HCT 25 mg alone and placebo in hypertensive adults.

This is a 12-month phase 2, prospective, open label study to evaluate the effect of rituximab with mycophenolate mofetil (MMF)on the PRA of 14 highly sensitized patients who just completed an 8 month trial of MMF treatment alone. PRA values obtained at study enrollment and at 6 and 12 months on combined therapy as well as the rates of transplant will be compared and evaluated using descriptive analysis.

This study will evaluate the safety and efficacy of amlodipine plus valsartan in patients with hypertension and left ventricular hypertrophy

The purpose of this study is to compare the blood pressure lowering efficacy of valsartan/hydrochlorothiazide (HCTZ) compared to hydrochlorothiazide for the treatment of obese hypertensive (mean sitting systolic blood pressure [MSSBP] >150 mmHg) patients.

The clinical study compares safety and efficacy of MK0507A (dorzolamide 1.0% / timolol 0.5%) with 1) timolol 0.5% and with 2) concomitant therapy with dorzolamide 1.0% / timolol 0.5% in patients with glaucoma and ocular hypertension.
