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 oral mucositis (OM) to 20%. We plan to enroll 25 patients at our institution in 12 months after the trial opens.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Amount of Narcotic Analgesia Use During Treatment		From beginning of therapy up to 3 months after completion of therapy
Other	Number of Participants With Breaks in Treatment	Breaks in treatment defined as one of the following: Missing at least 1 chemotherapy treatment; dose reduction in planned cisplatin administration; OR 3 consecutive days of no radiation therapy secondary to mucositis	Date of completion of chemoradiation therapy
Other	Percent Change in Body Weight During the Course of Treatment	The percent change in body weight was computed by subtracting the baseline weight from the weight after completion of treatment and dividing that quantity by the baseline weight. The confidence interval is estimated using the t distribution.	From date of enrollment until the date of completion of chemoradiation therapy, assessed up to 3 months after completion of therapy
Other	Number of Participants Who Require Feeding Tube Placement During Treatment (Excluding Patients Who Received a Prophylactic Feeding Tube Prior to the Initiation of Therapy)		At the date of completion of chemoradiation therapy
