Pharyngeal Electrical Stimulation Evaluation for Dysphagia After Stroke (PhEED)
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Randomization will be stratified at each site in a 1:1 fashion. All patients will have the Phagenyx® Catheter placed prior to randomization, and will receive either an active treatment of Pharyngeal Electrical Stimulation (PES) or a sham treatment performed by a health care professional (HCP) that is un-blinded to treatment assignment. All other speech pathology standard dysphagia care will be provided by a speech language pathologist (SLP) that is blinded to treatment assignment. Administration of all protocol-specific assessments will be conducted by personnel blinded to treatment assignment.
The study will follow an adaptive group sequential design with unblinded sample size re-assessment. To ensure 180 evaluable patients with 7-day data and assuming a 20% dropout rate, 225 patients will be enrolled initially. An interim analysis for futility will occur after the first 60 patients complete their 7-day visits and another interim analysis will be performed for efficacy and futility after 120 patients complete their 7-day visits. The total sample size may be increased up to 338 patients after the second interim analysis to ensure up to 270 evaluable patients. Up to 15 investigational centers across the US and possibly Europe will participate in this study. The enrollment period is expected to be approximately 24 months and patient participation will last for approximately 11 weeks. Patients will be assessed at the following intervals: baseline, 48 hours, 7 days, 14 days or at discharge, whichever is first, and 11 weeks after completion of the study treatments.

- Distorted oropharyngeal anatomy (e.g., pharyngeal pouch, major pharyngeal surgery or head /neck surgery)
- Currently being treatment for pneumonia.
- Mute, global aphasia; no usable speech or auditory comprehension (scores 3 on NIHSS question 9, Best Language)
- NIHSS score of >25
- Presence of a tracheostomy
- Any active implanted device (e.g., cochlear implant, ICD)
- Any progressive neurological disorder (e.g., Parkinson's Disease, Multiple Sclerosis)
- Cognitive impairment that prevents compliance with protocol-specific instructions and assessments

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Active group
patients randomized to receive active PES
|
The PES system is a two-part neurostimulation system.
It is composed of a durable component called the Base Station and the single-use sterile disposable Phagenyx® Catheter.
The Base Station acts as the user interface and provides the means to generate, optimize and monitor the delivery of electrical stimulation.
Other Names:

Sham Comparator: Sham treatmment
Patients randomized to sham will not receive any PES.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
To evaluate the efficacy of treatment in reducing the severity of unsafe swallows based on PAS(Penetration Aspiration Scale)of each swallow during VFSS
Time Frame: 48 hours post final treatment
|
VFSS (Vidoeflouroscopic Swallow Study) Swallowing safety of a bolus of thin and nectar consistency determined by a videofluoroscopic swallowing study.The PAS provides a scoring mechanism for airway closure and clearance during the VFSS. The PAS is a validated 8-point scale that measures penetration and aspiration. Scores are determined primarily by the depth to which material passes into the airway.

48 hours post final treatment

Secondary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
To evaluate the efficacy of Phagenyx® treatment in improving nutritional management
Time Frame: 11 weeks post final treatment
|
Nutritional management changes will be evaluated via: Time from baseline to removal of enteral feeding (i.e., removal of NG tube or PEG or transition to oral feeding, or first diet upgrade,Functional Oral Intake Scale (FOIS) at 7 days, 14 days or discharge, whichever is first, and 11 weeks |
11 weeks post final treatment
