Abdominal Binders to Treat Orthostatic Hypotension in Parkinsonian Syndromes (ABOH-PS)

Abdominal Binders to Treat Orthostatic Hypotension in Parkinsonian Syndromes: a Randomized, Placebo-controlled, Double-blind, Crossover Phase II Trial

The purpose of the present clinical trial is to determine whether the use of an elastic abdominal binder is effective in the non-pharmacological management of symptomatic, neurogenic orthostatic hypotension (OH) in individuals suffering from Parkinson's disease (PD) or Parkinson variant multiple system atrophy (MSA-P).

Study Overview

• Status: Recruiting
• Conditions: Parkinson Disease; Multiple System Atrophy, Parkinson Variant; Orthostatic; Hypotension, Neurogenic
• Intervention / Treatment: Device: Elastic abdominal binder; Device: Placebo binder

Detailed Description

This is a monocentric, randomized, placebo-controlled, double-blind, crossover phase II clinical trial with an open-label treatment extension phase. The investigators plan to recruit n = 30 individuals with MSA-P or PD with known or suspected OH.

At the Screening Visit, after patient information and written informed consent, the participants will first undergo a comprehensive neurological and cardiological evaluation, as well cardiovascular autonomic function testing to confirm the diagnosis of symptomatic, neurogenic OH.

Afterwards, the participants will be asked to wear physical activity monitoring (PAM) sensors for five consecutive days and to measure the blood pressure (BP) regularly following a home BP diary (i.e. Home Phase I).

On treatment day-1 (i.e. Visit 1), the participants will undergo an instrumented in-lab gait analysis, followed by a head-up tilt and active standing test. Afterwards, they will wear the first type of binder for two hours (either the investigational elastic abdominal binder or the placebo-comparator binder, depending on the randomization assignment). At the end of the two hours, the participants will repeat the in-lab gait analysis and the head-up tilt-/active standing test.

After one-day wash-out, the same procedure of treatment day-1 (i.e. Visit 1) will be repeated with the outstanding type of binder (i.e. treatment day-2, Visit 2).

At the end of this, all participants will be invited to wear the investigational elastic abdominal binder and the PAM sensors for five more days and to repeat the home BP measurements (i.e. Home Phase II).

A final follow-up visit is scheduled to return the PAM sensors, the BP monitor and to detect eventual adverse and serious adverse events occurred during Home Phase II.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Placebo Comparator: Placebo binder first; Participants in this arm will wear the placebo comparator ("Clima Care" body warmer, Bort Medical GmbH) for 2 hours on treatment day-1 (i.e. Visit 1), followed by the active comparator ("ABDO-SYNCRO 3-BAHNIG" elastic abdominal binder, SYNCRO-MED GmbH) for 2 hours on treatment day-2 (i.e. Visit 2).	Device: Elastic abdominal binder; The "ABDO-SYNCRO 3-BAHNIG" is an elastic abdominal binder with a 3-stripes Velcro fastening, capable of developing a 20 ± 2 mmHg pressure on the abdominal wall. This device will be tested as potentially beneficial with respect to the mentioned primary and secondary outcomes. The investigators anticipate to use this elastic abdominal binder, since participants of a previous trial reported this device to be comfortable enough and to have used it regularly during the open-label follow-up phase. Size will be chosen depending on the abdominal circumference of the participant, according to the size tables provided from the manufacturer (SYNCRO-MED GmbH).; Other Names: "ABDO-SYNCRO 3-BAHNIG" elastic abdominal binder, SYNCRO-MED GmbH; Device: Placebo binder; "Clima Care" is a simple body warmer, developing maximal 3±2 mmHg pressure on the abdominal wall.
