Study summary

The automated inflatable abdominal binder is an investigational device for the treatment of orthostatic hypotension (low blood pressure on standing) in patients with autonomic failure. The purpose of this study is to determine safety and effectiveness of the automated abdominal binder in improving orthostatic tolerance in these patients.

Read the detailed description

This is a randomized, double-blind, sham-controlled, parallel group study to compare the efficacy of the automated abdominal binder (inflated to 40 mm Hg) versus sham treatment (abdominal binder inflated to 5 mm Hg) in improving orthostatic tolerance in patients with primary autonomic failure disabled by orthostatic hypotension.

Potential participants will be admitted to the Vanderbilt Clinical Research Center for evaluation of inclusion and exclusion criteria. Eligible patients will be randomized to the active or sham binder group. Patients will then be asked to participate on three separate study days, two days apart: one day for baseline measurements (placebo pill t.i.d), one day for treatment with 10 mg midodrine t.i.d (standard of care), and one day for treatment with active or sham binder combined with placebo pill t.i.d. The order of the study days will be randomized. On each study day, blood pressure and heart rate will be measured while sitting, lying down, standing and walking during the Morning Orthostatic Trial, and posture and walking tests.

Inclusion criteria

  • Male and female subjects, age 40-80 years.
  • Possible or probable Multiple Systems Atrophy and Pure Autonomic Failure as defined by Consensus Criteria.
  • Neurogenic orthostatic hypotension defined as a ≥30-mm Hg decrease in SBP within 3 minutes of standing associated with impaired autonomic reflexes determined by autonomic testing in the absence of other identifiable causes, and
  • Moderate to severe orthostatic symptoms, defined as an Orthostatic Hypotension Symptom Assessment (OHSA) composite score ≥4 (self-rating Likert scale of 0 to 10, with 0 reflecting absence of symptoms), within the first 10 minutes of the screening orthostatic stress test, and that have an impact in quality of life, as defined by the patient.
  • Able and willing to provide .

Exclusion criteria

Exclusion Criteria:

  • Pregnancy.
  • Systemic illnesses known to produce autonomic neuropathy, including but not limited to diabetes mellitus, amyloidosis, monoclonal gammopathies, and neuropathies.
  • History of known aortic aneurisms, thoracic, abdominal or pelvic surgery in the past 6 months; symptomatic abdominal or inguinal hernias; severe gastroesophageal reflux; recent fractures or fissures of ribs, thoracic or lumbar spine; medical devices implanted on the abdominal wall or abdomen that would interfere with the binder; known abdominal or pelvic tumors, cysts or enlarged spleen; intolerance to any increase in intraabdominal pressure.
  • Pre-existing sustained supine hypertension ≥180/110.
  • Bedridden patients or those who are unable to stand due to motor impairment or severe orthostatic hypotension.
  • Clinically unstable coronary artery disease (recurrent angina despite medical therapy), or major cardiovascular or neurological event in the past 6 months (myocardial infarction, stroke or ).
  • Concomitant use of anticoagulants
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

TIA (transient ischaemic attack)

A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.

Stroke symptoms need emergency care at once, even if they go away.

Study arms

  • Experimental
    Automated Abdominal Binder

    Participants will be studied on three separate study days, two days apart: one day for baseline measurements (placebo pill t.i.d), one day for treatment with 10 mg midodrine t.i.d (standard of care), and one day for treatment with the automated abdominal binder combined with placebo pill t.i.d The automated abdominal binder will be placed during the morning orthostatic trial on the active/sham binder study day. The binder will inflate automatically (\~40 mmHg) every time the participant stands up throughout the study day.

  • Sham comparator
    Sham binder

    Participants will be studied on three separate study days, two days apart: one day for baseline measurements (placebo pill t.i.d), one day for treatment with 10 mg midodrine t.i.d (standard of care), and one day for treatment with the sham binder combined with placebo pill t.i.d. The sham binder will be placed during the morning orthostatic trial on the active/sham binder study day. The sham binder will inflate automatically (\~5 mmHg) every time the participant stands up throughout the study day.

Interventions

  • Deviceautomated abdominal binder

    The binder automatically inflates every time the participant stands up to apply a compression level of about 40 mmHg. Participants will wear the device throughout the active/sham study day.

  • DeviceSham binder

    The binder automatically inflates every time the participant stands up to apply a compression level of about 5 mmHg. Participants will wear the device throughout the active/sham study day.

  • DrugPlacebo

    Oral placebo will be given three times a day on the baseline day (placebo)

  • A midodrine pill 10mg will be given three times a day on the standard of care study day

What researchers measure

Primary outcomes

  1. Orthostatic tolerance

    orthostatic tolerance is defined as the area under the curve of the upright systolic blood pressure (AUCSBP) during the Morning Orthostatic Trials

    Time frame: After 10 minutes of standing (or as tolerated) during the Morning orthostatic trial on the automated binder/sham study day

  2. Orthostatic Hypotension Symptom Assessment (OHSA) Score

    The Orthostatic Hypotension Symptom Assessment (OHSA) Score is the part I of the Orthostatic Hypotension Questionnaire (OHQ). It consists of six questions, each rating the intensity of one characteristic symptom of orthostatic hypotension: 1. Dizziness, lightheadedness, feeling faint, or feeling like you might black out; 2. Problems with vision (blurring, seeing spots, tunnel vision, etc.); 3. Generalized weakness; 4. Fatigue; 5. Trouble concentrating; and 6. Head/neck discomfort.The items are scored on an 11-point Likert scale from 0 to 10, with 0 indicating no symptoms and 10 indicating the worst possible symptoms. Composite score is the average of the item scores obtained at the post-intervention stand period during the Morning Orthostatic Trials

    Time frame: After 10 minutes of standing (or as tolerated) during the Morning orthostatic trial on the automated binder/sham study day

Secondary outcomes

  1. Upright time

    Sum of standing and walking times

    Time frame: After 10 minutes of standing and 15 minutes waking (as tolerated)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 5, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
