Filter by:We are seeking male and female patients to voluntarily take part in a clinical research study. Patients must be aged 18 or older and diagnosed with symptomatic orthostatic hypotension (low blood pressure while in the upright position) due to Parkinson's disease, multiple system atrophy, pure autonomic failure or autonomic neuropathies (i.e. neurogenic orthostatic hypotension). Symptoms of low blood pressure include dizziness, lightheadedness, changes in vision and generalized weakness upon standing. The main effect of the drug being studied is to increase blood pressure in the upright position so symptoms will decrease. The purpose of this clinical study is to further assess the clinical effect of high dose midodrine hydrochloride (ProAmatine®), an approved treatment for orthostatic hypotension. During the course of the study, participants will receive either ProAmatine® or a placebo. Assessments will be made using questionnaires that measure symptom and activity levels. Blood pressure in the lying down, sitting and standing positions will be measured. Patients will also complete standing time assessments. They will be asked to remain standing without moving until they feel sufficiently lightheaded, or dizzy, or feel faint so that they would feel more comfortable sitting down.
The clinical use of IL-2 is currently limited by development of dose-dependent hypotension (systolic blood pressure (SBP) < 90 mm Hg). The overall outcome is constant across sites with 20-50% of the patients requiring ICU management because of unresponsive hypotension and hyporeactivity (loss of response to vasoconstrictors). Because of the dose-limiting side effects, the duration of IL-2 dosing is frequently curtailed. Thus, hemodynamic toxicities have limited the usefulness of IL-2 therapy. M40403 has prevented both the hypotension and hyporeactivity associated with IL-2 treatment in preclinical studies. This trial will study the safety and efficacy of M40403 in the prevention or reduction of hypotension in patients receiving IL-2 therapy.
Please note that the continuation study can be found at http://clinicaltrials.gov/show/NCT00633880. RATIONALE: Neurogenic hypotension is a fall in blood pressure that occurs when one moves from a lying down to a standing position or after eating a meal. It causes one to feel dizzy, light headed, and weak. Neurogenic hypotension is caused by a problem in the part of the nervous system that controls such functions as heart rate and blood pressure. Droxidopa, a drug that may increase blood pressure, may be an effective treatment for neurogenic hypotension. PURPOSE: Clinical trial to study the effectiveness of droxidopa in treating patients who have neurogenic hypotension.
OBJECTIVES: I. Study further the safety and efficacy of the alpha-receptor agonist midodrine in patients with neurogenic orthostatic hypotension. II. Assess the quality of life in these patients with this treatment regimen.
