RESULTS

Found (49) clinical trials

This double blind study will evaluate the effect of the drug TD-9855 on participants with Neurogenic Orthostatic Hypotension in improving the symptoms.

Phase

This is a multi-site, placebo-controlled, double-blind, randomized-withdrawal study evaluating the durability of clinical benefit of a study drug for patients with symptomatic neurogenic orthostatic hypotension. This study has a duration of up to 36 weeks, consisting of 5 periods:  Screening Period: up to 4 weeks duration;  Open-Label Titration Period (Titration ...

Phase

To evaluate the time to treatment intervention in patients with Parkinson's Disease (PD), Multiple System Atrophy (MSA), Pure Autonomic Failure (PAF), Non-Diabetic Autonomic Neuropathy (NDAN) or Dopamine Beta Hydroxylase (DBH) Deficiency who have been previously stabilized with droxidopa therapy for symptoms of neurogenic orthostatic hypotension (NOH) (dizziness, light-headedness, or feelings ...

Phase

Gait Analysis in Neurological Disease

This study aims to determine whether the gait patterns in these subjects differ in predictable and quantifiable ways from those of age- and sex-matched healthy controls. This will be conducted by asking 40 Parkinsonian disorder subjects and 40 age-matched healthy control subjects to walk 9 trials over an 18 ft ...

Phase N/A

Biomarkers in Parkinsonian Syndromes

The differential diagnosis between Parkinson's disease, multiple system atrophy and progressive supranuclear palsy can be very difficult in early disease. PD, MSA and PSP are neurodegenerative disorders. PD and MSA belong to the alpha-synucleinopathies, which are characterized by the abnormal accumulation of alpha-synuclein. Alpha-synuclein accumulates in intraneuronal Lewy bodies in ...

Phase N/A

Natural History Study of Synucleinopathies

-synuclein is a small protein of 140 amino acids that is highly expressed in the brain. It's function remains poorly understood.10 Synucleinopathies are a group of neurodegenerative diseases associated with the abnormal accumulation of -synuclein within cytoplasmic inclusions in neurons or oligodendroglia. These -synuclein containing cytoplasmic aggregates occur throughout the ...

Phase N/A

Treatment of Post-SCI Hypotension

Baseline Testing: Subjects will visit the testing laboratory on the SCI Rehabilitation Unit for baseline data collection, prior to initiation of the treatment protocol. Upon arrival, subjects will be placed in the supine position on an adjustable surface for instrumentation, which will be conducted in a quiet, dimly lit, thermo-neutral ...

Phase

Overnight Trials With Heat Stress in Autonomic Failure Patients With Supine Hypertension

Primary autonomic failure is a neurodegenerative condition characterized by loss of efferent sympathetic function and severe baroreflex impairment. The clinical hallmark of autonomic failure is disabling orthostatic hypotension, but at least half of patients are also hypertensive while lying down. This supine hypertension can be severe and associated with end-organ ...

Phase N/A

Effects of Midodrine and Droxidopa on Splanchnic Capacitance in Autonomic Failure

Patients with multiple system atrophy, pure autonomic failure or Parkinson disease, and orthostatic hypotension will be studied in a randomized, double-blind, 2-arm parallel design to compare the effects of droxidopa and midodrine on stoke volume during head up tilt. A total of 34 participants will be enrolled in the study ...

Phase

Reduction in Splanchnic Capacitance Contributes to Sympathetically Dependent Hypertension in Autonomic

The investigators will study male and female subjects, age 40-80 years with possible or probable Multiple System Atrophy, as defined by Consensus Criteria who suffer from supine hypertension defined as SBP150, and neurogenic orthostatic hypotension, defined as a 30-mmHg decrease in systolic BP within 3 minutes of standing associated with ...
