Clinical Trial Summary

The objective of the study is to assess the effect early pneumatic compression (prior to confirming cancer-free status via PET or CT imaging) has on swallow outcomes, positron emission tomography (PET) measurements, function, and complication rate post-radiotherapy in subjects treated for oropharyngeal cancer.

Description:

This is a single-center, prospective, randomized, two-arm, wait-list control study that plans to enroll a total of 24 subjects in the United States. A baseline screening will take place where all subjects who provide consent and meet the eligibility criteria following completion of radiotherapy will begin a 6 weeks regimen of in-home swallow exercises. They will then return to the clinic for final screening and randomization into one of two treatment groups: Flexitouch Plus Cellular Connectivity (FT-CC) and Swallow Exercises (Intervention) or Swallow Exercises alone (Standard Care). A total of 3 in-clinic visits and 1 phone call will be conducted over a 12-week period. The Standard Care group will be offered an optional 6 week follow-up period to use the device in-home and will be seen in the clinic for one additional follow-up Visit 2. A reading center with personnel blinded to treatment assignment will be used to interpret the MBS and PET study results.

3. Poorly controlled: kidney disease (glomerular filtration rate < 30 mls per minute), hypoproteinemia, pulmonary hypertension, hypothyroidism or parathyroidism, cyclic edema, or Munchausen Syndrome (for which endocrinologist recommends against neck compression)

4. Carotid sinus hypersensitivity syndrome

6. Symptomatic bradycardia in the absence of a pacemaker

7. Internal jugular venous thrombosis (within 3 months)

8. Increased intracranial pressure or other contraindications to internal or external jugular venous compression

9. Acute radiation dermatitis, unhealed surgical scar, unhealed or open wounds, surgical flap less than 6-8 weeks post-operative

10. Facial or head and neck dermal metastasis

11. Acute infection/inflammatory disease of the head and neck region (e.g., facial infection, parotid gland abscess, acute cellulitis, or other uncontrolled skin/untreated head and neck inflammatory skin disease)

12. Any condition in which increased venous and lymphatic return is undesirable

13. Heart failure (acute pulmonary edema, decompensated acute heart failure)

14. Subject is pregnant or trying to become pregnant

15. Acute venous disease (acute thrombophlebitis, acute deep venous thrombosis, acute pulmonary embolism)

16. The subject has comorbidities which, in the opinion of the investigator, will not be appropriate for the study or the subject has an estimated life expectancy of less than 1½ months

17. Any subject who is considered to be part of a vulnerable population (e.g., prisoners or those without sufficient mental capacity)

18. The subject has participated in any investigational drug or device research study within 30 days of enrollment

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	PET Measurements - Epiglottic Thickness	A measurement of the epiglottic thickness.	Changes between Baseline and 12-Week Follow-Up
Other	PET Measurements - Prevertebral Space	A measurement of the prevertebral space.	Changes between Baseline and 12-Week Follow-Up
Primary	Swallow outcomes via modified barium swallow - Penetration-Aspiration Scale (PAS)	PAS is an eight-point ordinal severity scale scoring the depth of airway invasion by the bolus, whether it is expelled from the airway as well as any patient reaction. It ranges from one (material does not enter the airway) to eight (material enters the airway, passes below the vocal folds, and no effort is made to eject). Min value = 1, Max value = 8, the lower the score the better.	Changes between Baseline, 6-Week Follow-Up, 12-Week Follow-Up, and 18-Week Follow-Up
Primary	Swallow outcomes via modified barium swallow - Pharyngeal Constriction Ratio (PCR)	PCR is calculated by dividing the pharyngeal area (cm2) of the bolus hold frame (PAHOLD) by the maximum pharyngeal contraction frames (PAMAX). Min value = 0, Max value = 1. The lower the score, the better the outcome.	Changes between Baseline, 6-Week Follow-Up, 12-Week Follow-Up, and 18-Week Follow-Up
Primary	Swallow outcomes via modified barium swallow - Upper Esophageal Sphincter Opening (UESmax)	UES measurements will include the: (1) maximum width of the UES opening as defined by the line between the anterior and posterior walls of the pharyngoesophageal segment at its narrowest area during its maximum opening in a lateral view, and (2) the maximum width of the UES opening as viewed anteriorly. Min value = 0, max value = 2. Greater the score, the better the outcome.	Changes between Baseline, 6-Week Follow-Up, 12-Week Follow-Up, and 18-Week Follow-Up
Primary	Swallow outcomes via modified barium swallow - Esophageal Bolus Transit Time (ETT)	The time it takes the bolus to get through the cricopharyngeal muscle (where the esophageal phase is initiated) to the bottom of the esophagus (at the junction of the lower esophageal sphincter). Min value = 0, max value = 60. The lower the score, the better the outcome (seconds).	Changes between Baseline, 6-Week Follow-Up, 12-Week Follow-Up, and 18-Week Follow-Up
Primary	Swallow outcomes via modified barium swallow - Normalized residue ratio scale (NRRS)	Pharyngeal residue is the term used to describe material that remains in the pharynx post swallow (also called retention or stasis). The NRRS is calculated using ImageJ pixel area measures of residue in the valleculae. Min value = 0, max value = 1. The lower the score, the better the outcomes.	Changes between Baseline, 6-Week Follow-Up, 12-Week Follow-Up, and 18-Week Follow-Up
Primary	Swallow outcomes via modified barium swallow - Posterior Pharyngeal Wall Thickness (PPW)	PPW is the thickness of the posterior pharyngeal wall in lateral view while holding a 1-ml liquid bolus in oral cavity prior to swallow (PPWhold). Min value = 0, max value = 30. The lower the score the better the outcomes (mm)	Changes between Baseline, 6-Week Follow-Up, 12-Week Follow-Up, and 18-Week Follow-Up
Primary	Function - Stimulated Saliva Secretion Rate	Stimulated Saliva Secretion Rate is the measure of total saliva collected in 3 minutes while chewing gum.	Changes between Baseline, 6-Week Follow-Up, 12-Week Follow-Up, and 18-Week Follow-Up
Primary	Swallow outcomes via patient reported outcome measure - Eating Assessment Tool (EAT-10) Questionnaire Score	Min value = 0, max value = 4. The lower the score the better the outcome.	Changes between Baseline, 6-Week Follow-Up, 12-Week Follow-Up, and 18-Week Follow-Up
Primary	Patient Reported Function - Voice Handicap Index (VHI-10)	A survey that quantifies the functional, physical, and emotional impacts of a voice disorder on a subject's quality of life. It captures the subject's subjective rating of a series of 10 questions. Min value = 0, max value = 40. The lower the score the better the outcomes.	Changes between Baseline, 6-Week Follow-Up, 12-Week Follow-Up, and 18-Week Follow-Up
Primary	Patient Reported Function - Functional Assessment of Cancer Therapy - Head and Neck (FACT HN)	A survey which inquires on a series of concerns related to the head and neck region including oral comfort, breathing, voice, eating, appearance, tobacco, alcohol, and communication. The subject is asked to indicate how important each of the 39 listed concerns have been in the past 7 days. Min value = 0, max value = 148. The higher the score the better the quality of life.
