Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The overall purpose of this clinical study is to evaluate safety and efficacy of the MuReva Phototherapy System with a light delivery mouthpiece to reduce the severity of oral mucositis (OM) in adult patients with squamous cell carcinoma of the oral cavity, oropharynx, tonsils and base of tongue receiving radiation therapy with or without concurrent chemotherapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Study Design: A prospective, multi-center, randomized, double-blind, placebo controlled, adaptive sample size, two-treatment parallel, pivotal clinical study.

Protocol-eligible subjects will be randomized in a 1:1 allocation to receive either the active MuReva Phototherapy System or a sham control. Both the subjects and clinician evaluating the patients will be blinded to the treatment assignments. The sham device will be placed in the patient's mouth and operated in the same manner as the active device, but not deliver any therapy.

Subjects will begin device treatment sessions on the first day of radiation treatment (RT) and will continue to receive once daily treatments prior to RT with their assigned device for 5 days per week for the duration of their RT treatment (approximately 6 to 8 weeks, for a total of 30 to 40 device sessions depending on the standard of care regimen for the type of cancer). Each device treatment session will last approximately 10 minutes in total. Light therapy parameters for the MuReva Phototherapy System will be as follows for all subjects receiving active light therapy: 660nm, 2-12 J/cm2 nominal fluence. Subjects who stay on RT treatment past 6 weeks will continue to receive treatment with their assigned devices up through 8 total weeks of treatment (for a maximum total of 40 phototherapy sessions). In addition, all subjects, regardless of randomization, will be kept on standard oral care, oral hygiene and oral pain protocols.

All subjects will visit the study site once during the Screening period (Days -28 to 1) and an anticipated 30 to 40 times during the treatment period (i.e., 5 days during each of the 6-8 RT treatment weeks). Weekly, subjects will be evaluated for oral mucositis and for device safety. The weekly assessments will continue through the final RT session. A post-therapy assessment will be done approximately 2 weeks after completion of RT. At the conclusion of this assessment each subject's participation in the study will be complete.

Blinding Strategy

TRIPLE

Participants Investigators Outcome Assessors

The sponsor, clinical research organization (CRO), subjects, research staff and Investigators performing the weekly OM evaluations for the study will be blinded to the treatment assignments. Subjects will be mandated to use light-blocking eyewear.

Only the research staff delivering treatment will be unblinded. No other personnel or visitors will be allowed in the treatment room during active/sham treatment.

The Investigators will not administer the daily treatment and will not visit or observe the patient during device use in order to remain blinded. The Investigators will also remain blinded to the patients' responses to the weekly Self-Assessments.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Active Device Treatment Cohort - Chemoradiation therapy

The MuReva Phototherapy System consists of Light Control Unit and two Mouthpiece Cable Assemblies. Subjects will begin device treatment photobiomodulation sessions on the first day of radiotherapy (RT) treatment. They will receive once-daily investigative device photobiomodulation treatments prior to radiation therapy (RT) with their assigned Mouthpiece for 5 days per week for the duration of their CRT treatment. Each device treatment session will last up to 5 minutes, not including up to 5 additional minutes for treatment breaks. All subjects will visit the study site once during the Screening period (Days -28 to 1) and an anticipated 30 to 40 times during the treatment period. Each patient will be assigned their own Mouthpiece Cable Assembly set.

Sham Device Treatment Cohort- Chemoradiation therapy

The MuReva Phototherapy System (or sham control) is a Light Control Unit and a set of Mouthpiece Cable Assemblies. The sham control Mouthpiece Cable Assemblies will appear identical to the active Mouthpiece Cable Assembly, and will be used in the same manner as the active cohort. However, the sham control device will be configured where the mouthpiece will not emit any light at any time during the study. The same Light Control Unit will be used with sham and active Mouthpiece Cable Assemblies. Each patient will be assigned their own Mouthpiece Cable Assembly set.
