Recruitment & Eligibility

Status: Completed

Sex: All

Target Recruitment: 85

Within 28 days of Screening, subject is scheduled to receive a continuous course of Intensity-Modulated Radiation Therapy (IMRT) over an estimated 6 to 8 weeks (treatment week is defined as 5 fractions per week). The initial target volume encompassing the gross and subclinical disease sites will receive 5 fractions per week with a minimum cumulative dose of 50 Gray (Gy) for low to intermediate risk (sites of suspected subclinical spread) and maximum cumulative dose of 70 Gy for gross tumor volume/High risk (Primary tumor and involved lymph nodes). 3. The subject's planned radiation treatment fields include a minimum of 50 Gy to at least two oral cavity sites (i.e. buccal mucosa, floor of mouth, ventral tongue, lateral tongue, dorsal tongue, hard palate, and soft palate). 4. If the subject is receiving concurrent chemotherapy, the treatment plan includes Cisplatin administered in either a standard weekly (30-40 mg/m2) or approximately every 21 days (80-100mg/m2) regimen OR Carboplatin administered in standard weekly (1.0-2.0 AUC) regimen WITH/WITHOUT Paclitaxel administered in a standard weekly (30-45mg/m2) regimen. 5. Subject is at least 22 years of age. 6. Subject has no dental or oral health conditions that would preclude daily use of a mouthpiece and demonstrates capability in sustaining mouthpiece in oral cavity for recommended time during Screening procedure. 7. Subject has an Eastern Cooperative Oncology Group (ECOG) Performance Status of = 2. 8. Subject is able to read and understand the Informed Consent Form (ICF) and has voluntarily provided written informed consent. 9. For the entire duration of their treatment, the subject will not use any tobacco or nicotine products with the exception of nicotine patches. 10.

Subject is currently receiving or has previously received chemotherapy or chemoradiotherapy within the past 2 years and the oral cavity has not yet fully recovered. 2. Subject is given neo-adjuvant or induction chemotherapy for Head and Neck cancer prior to starting RT. 3. Subject has been diagnosed with another type/site of cancer that has not been controlled. 4. Subject is pregnant or nursing. 5. Subject is receiving medications indicated for the treatment and/or prevention of mucositis (e.g., palifermin). 6. Subject has had prior radiation to the head and neck. 7. Subject has a diagnosis that is prone to affect wound healing, e.g., uncontrolled diabetes. 8. Subject has trismus with an interincisal distance of 30mm or less. 9. Subject has an active infection in the oropharynx and/or oral cavity (any infection in the oropharynx and/or oral cavity at the time of screening must be addressed prior to first radiation treatment). 10. Subject has a salivary disturbance, e.g., Sjögren's syndrome. 11. Subject has any grade of oral mucositis per WHO Oral Toxicity Scale. 12. Subject is receiving, or has received in the last 30 days, an investigational treatment, therapy, or medical device outside of this clinical study protocol. 13. Subject has a Baseline mouth pain score of greater than 5 out of 10 on question 6 of the OMWQ-HN. Exception can be made if Principal Investigator determines the cause of mouth pain is due to tumor or surgery site pain. 14. Subject is unable to participate in the study because of a concurrent or recent disease state that, in the opinion of the Principal Investigator, would affect the study endpoints, e.g., dental disease or COVID-19 (active or recovered). 15. Subject has 8 or more dental prostheses or implants. 16. Subject is not considered eligible at the discretion of the oral maxillofacial dentist/surgeon. Exception can be made if all items identified on the dental exam have been addressed prior to first radiation treatment. 17.
