Trial Outcomes & Findings for Non-invasive Vagal Neurostimulation (nVNS) in Adolescents With Postural Orthostatic Tachycardia Syndrome (POTS) (NCT NCT06268288)

NCT ID: NCT06268288

Last Updated: 2025-10-31

Results Overview

The change in COMPASS-31 score from baseline to 8 weeks. COMPASS-31 measures autonomic dysfunction in patients with neurodegenerative diseases. It consists of 31 patient-reported questions assessing various symptoms, including orthostatic intolerance, vasomotor symptoms, and gastrointestinal issues. Total scores range from 0 to 100, with higher scores indicating more severe symptoms.

Standard Postural Orthostatic Tachycardia Syndrome management/ STEPS
The General Pediatric and Adolescent Medicine providers at Mayo Clinic utilized a specific management program for their patients with Postural Orthostatic Tachycardia Syndrome utilizing the acronym STEPS. S is for liberal intake of salt, T is for drinking 90-100 ounces/day of fluid, E is for slowly and gradually improve continuous aerobic exercise duration to a goal of 50 minute most days of the week, P is for possible utilization of 1 of two prescription medications (metoprolol or midodrine), and S is for setting priorities and goals such as encouraging good sleep hygiene, attendance at school, social interactions, and counseling. STEPS management protocol: STEPS is the acronym for the standard management program for our patients with POTS. It includes liberal use of salt, taking in 90-100 ounces of fluid, gradually increasing the duration of aerobic exercise, possible use of one of two prescription medications (metoprolol, and midodrine), and encouragement to set priority and goals
STEPS + GammaCore Intervention (noninvasive vagal nerve stimulation)
Utilization of STEPS management goals plus the addition of non invasive vagal nerve stimulators for two 2 minutes of intervention performed three times a day. GammaCore intervention: Use of the vagal nerve stimulator, GammaCore, on the right side of the neck for two 2 minute stimulations performed 3 times a day STEPS management protocol: STEPS is the acronym for the standard management program for our patients with POTS. It includes liberal use of salt, taking in 90-100 ounces of fluid, gradually increasing the duration of aerobic exercise, possible use of one of two prescription medications (metoprolol, and midodrine), and encouragement to set priority and goals

PRIMARY outcome

Timeframe: Baseline; 8 Weeks

Population: Everyone had a baseline head up tilt table test. The repeat tilt table test was voluntary and resulted in fewer patients participating in this repeat test. The reason we made this voluntary is that many participants live far away and return for a repeat head up tilt table is inconvenient and costly.

The change in heart rate, measured in beats per minute (BPM), in the head up tilt table test (HUTT) from baseline to 8 weeks.

SECONDARY outcome

Timeframe: Baseline; 8 Weeks

Population: Seven patients in the Device group and seven patients in the Control group had incomplete data for the PHQ-9 scores (missing either the baseline PHQ-9 survey or the final PHQ-8 at 8 weeks).

The change in the Patient Health Questionnaire 9-item (PHQ-9) scale score from baseline to 8 weeks. PHQ-9 is used to assess severity of depression. Scoring is calculated by assigning scores of 0, 1, 2, and 3 to the response categories, respectively, of "not at all," "several days," "more than half the days," and "nearly every day." Total score ranges from 0 to 27 where 0 is no depression, 1-4 is minimal depression, 5-9 is mild depression, 10-14 is moderate depression, and 15-19 is moderately severe depression and 20-27 severe depression.
