Clinical Trial Summary

The overall purpose of this study is to examine the efficacy of prophylactic low-level laser therapy (LLLT) to reduce the incidence of oral mucositis and adverse events in patients receiving combined modality therapy consisting of chemotherapy and radiation therapy for head and neck cancer.

Description:

A phase II, single-arm trial to examine the efficacy of prophylactic low-level laser therapy (LLLT) to reduce the incidence of oral mucositis and adverse events in patients receiving combined modality therapy consisting of chemotherapy and radiation therapy for head and neck cancer.

Patients meeting the eligibility criteria will be enrolled to receive prophylactic LLLT in addition to standard of care measures for oral mucositis or other toxicity of therapy. The radiation and chemotherapy dose, schedule, modality, technique, and any required adjustments will not be influenced by this protocol and will follow standard existing institutional practices.

Patients will receive LLLT three times per week concurrently with chemoradiotherapy. LLLT may be delivered either immediately prior to or after the patient's daily fraction of radiotherapy. Patients will be treated extra-orally with a THOR® LED cluster for one minute along the buccal mucosa on each side and intraorally for one minute to the tongue and soft palate. During each LLLT treatment session a thorough oral exam will be performed to identify any areas of mucositis. If the patient should develop intraoral lesions they will be targeted directly with the intraoral probe for one minute to each site of mucositis. The laser settings to be used are as follows: frequency 2.5 Hz; wavelength 660 nm; and power 75 mW, for an energy of 4.5 J.

Patients will be evaluated prior to therapy, weekly during therapy, two weeks after the completion of therapy, and three months after the completion of therapy. During each assessment, the following toxicities will be assessed: pain, mucositis, dysphagia, xerostomia, dysgeusia, dermatitis, trismus, and quality of life.

Previous studies indicate that approximately 40% of patients will experience severe mucositis with radiation and concurrent chemotherapy. The hypothesis in this trial is that the addition of LLLT to this treatment regimen will decrease the rate of severe acute OM to 20%. We plan to enroll 50 patients at our institution.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants With Severe (WHO Grade 3-4) Oral Mucositis	Percentage of participants with severe oral mucositis per the World Health Organization (WHO grade 3-4) (ulcerative lesions of the oral mucosa) in patients treated to a cumulative radiation dose of at least 5000 cGy.	Up to 1 year
Primary	Percentage of Participants With Severe (CTCAE v. 4.0 Grade 3-5) Oral Mucositis	The Percentage of participants with severe Common Terminology Criteria for Adverse Events (CTCAE, v. 4.0 grade 3-5) oral mucositis in patients treated to a cumulative radiation dose of at least 5000 cGy.	Up to 1 year
Secondary	Time to Onset of Oral Mucositis	Time to onset of severe oral mucositis following the initiation of radiotherapy. per Common Terminology Criteria for Adverse Events (CTCAE v. 4.0 grade 3-4) oral mucositis following the initiation of radiotherapy.	Up to 1 year
Secondary	Mean Cumulative Radiation Dose	Mean cumulative radiation dose at time of onset of severe oral mucositis per Common Terminology Criteria for Adverse Events (CTCAE v. 4.0 grade 3-4)	Up to 1 year
Secondary	Duration of Oral Mucositis	Time from onset of severe oral mucositis per Common Terminology Criteria for Adverse Events (CTCAE v. 4.0 grade 3-4). The duration of SOM is calculated as the time in days between the onset of SOM to the time when the patient is first found to recover from SOM. If the patient do not recover from SOM, the duration is censored at the last observation time.	Up to 1 year
Secondary	Percentage of Participants With Feeding Tube Replacement	Percentage of participants who require feeding tube placement during treatment.	Up to 1 year
Secondary	Percentage of Participants With Trismus	Percentage of Participants with trismus (reduced opening of the jaws determined via measurement of interincisal distance). The interincisal distance will be measured in millimeters at the patient's maximum comfortable extent of mouth opening.	Up to 1 year
Secondary	Quality of Life Via Functional Assessment of Cancer Therapy Head & Neck Cancer (FACT-HN) Questionnaire	This measure is based on a self-administered questionnaire. Responses to each item were on a Likert scale score ranging from 0 to 4. The individual responses were summed to compute subscale scores, and the subscales to compute overall total scores, with higher scores indicating better Quality of Life. FACT-HN includes 2 parts - FACT-G and FACT-HN. The basic FACT-G (general) is comprised of 27 items (0-108). Subscales include Physical Well-Being (0-28), Social/Family Well-Being (0-28), Emotional Well-Being (0-24), and Functional Well-Being, (0-28). Two "Relationship with physician" items (subscale score min/max = 0-8) were added to the FACT-G in this trial, for a total of 29 FACT-G items (total min/max = 0-116). The FACT-HN is comprised of 12 head and neck specific items (0-48). Thus, the overall total possible score range was 0-164. The FACT Head & Neck Trial Outcome Index is a composite score which includes only physical, functional, and FACT-HN, thus a score range from 0-104.	Up to 1 year
