N/A
Recruiting
Led By Italo Biaggioni, MD
Research Sponsored by Vanderbilt University Medical Center
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Possible or probable Multiple Systems Atrophy, Pure Autonomic Failure, or Parkinson's disease with neurogenic orthostatic hypotension.
Male and female subjects, age 40-80 years
Must not have
Bedridden, physically disabled, or unable to walk
Patients with Orthostatic hypotension symptom assessment (OHSA) score ≥ 6, or orthostatic systolic blood pressure drop ≥ 30 mmHg on their regular treatment
Timeline
Screening 3 weeks
Treatment Varies
Follow Up 7 days of treatment or placebo period

Summary

This trial is looking for a more objective way to assess the efficacy of treatments for neurogenic orthostatic hypotension, by using an activity monitor to track how long patients spend in the upright position during a week on placebo and a week on their regular medication.

Who is the study for?
This trial is for people aged 40-80 with conditions like Multiple Systems Atrophy, Pure Autonomic Failure, or Parkinson's disease who have low blood pressure upon standing. They must be on midodrine or atomoxetine treatment and not bedridden, pregnant, or have had recent major cardiovascular events.
What is being tested?
The study tests if an accelerometer can better measure the effectiveness of treatments for neurogenic orthostatic hypotension compared to questionnaires. Participants will take either their regular medication or a placebo pill while wearing the activity monitor.
What are the potential side effects?
Midodrine may cause scalp tingling, chills, urinary urgency; Atomoxetine might lead to dry mouth, insomnia, increased heart rate. Placebos typically do not cause side effects but can trigger a psychological response.
