GM-CSF Mouthwash for Preventing and Treating Mucositis in Patients Undergoing Radiation Therapy for Head and Neck Cancer

Marilyn Dodd91 enrolled

Overview

GM-CSF may protect normal cells from the side effects, such as mucositis, of radiation therapy and may help damaged tissue heal faster after radiation therapy. This randomized clinical trial is studying how well GM-CSF works in preventing and treating mucositis in patients who are undergoing radiation therapy for head and neck cancer.

OBJECTIVES: Primary * Compare the incidence of radiotherapy (RT)-induced oral mucositis of any grade, using the Radiation Therapy Oncology Group Acute Radiation Morbidity Scoring Criteria (RTOG ARMSC)-Mucous Membrane, in patients treated with 1 of 2 mouthwashes (sargramostim \[GM-CSF\] or salt and soda). (prevention portion of the study) * Compare the effectiveness of the 2 mouthwashes in treating oral mucositis as defined by the incidence of RTOG ARMSC-Mucous Membrane grade 3 and 4 mucositis in patients in 1 of 3 groups (salt and soda, continuing GM-CSF, or new GM-CSF). (treatment portion of the study) Secondary * Compare the effectiveness of the 2 mouthwashes in preventing RT-induced oral mucositis by the following direct indices: * Cumulative RT dose prior to onset of oral mucositis (prevention portion only) * Severity of RT-induced oral mucositis at onset and during treatment (using Oral Mucositis Assessment Scale (OMAS)) * Severity of oral mucositis-related pain at onset and during treatment (using OMAS) * Incidence of oral mucositis-related infection at onset and during treatment (using OMAS) * Severity of oral mucositis-related problems with ingestion of food and fluids at onset and during treatment (using OMAS) * Time to healing of RT-induced oral mucositis. * Evaluate patients using the following indirect indices of oral mucositis morbidity during the prevention and treatment portions of the study. * Tolerance to RT regimen * Functional status * Quality of life. OUTLINE: This is a multicenter, randomized, controlled, double-blinded study. Patients are stratified according to radiotherapy dose schedule (standard vs hyperfractionation vs intensity modulation) and concurrent chemotherapy (yes vs no). * Prevention (no mucositis): Patients are randomized to 1 of 2 treatment arms. * Arm I: Patients receive oral sargramostim (GM-CSF) mouthwash, holding it in their mouths and swallowing it in intervals over 1 hour once daily. * Arm II: Patients receive oral salt and soda mouthwash, holding it and swallowing it in intervals over 1 hour once daily. Treatment in both arms continues during 6-7 weeks of radiotherapy and/or the onset of mucositis. Patients also perform PRO-SELF: Mouth Aware (PSMA) twice daily. * Treatment (onset of mucositis): Patients who are currently using GM-CSF mouthwash continue use as in prevention. Patients who are currently using salt and soda mouthwash are randomized to 1 of 2 treatment arms. * Arm III: Patients receive GM-CSF mouthwash as in arm I. * Arm IV: Patients receive salt and soda mouthwash as in arm II. In both arms, treatment continues until the mucositis heals. Patients perform PSMA four times daily during and for 3 months after radiotherapy. Quality of life is assessed at baseline and periodically after radiotherapy. After completion of study treatment, patients are followed every once a month for 3 months.

Outcomes

Primary Outcomes

Comparison of Number of Participants With Grade 1 or 2 Oral Mucositis (GM-CSF and SS Groups Only)

The number of participants with recorded grade 1 (mild; Irritation, may experience slight pain, not requiring analgesic) or grade 2 (moderate; Patchy mucositis that may produce inflammatory serosanguinitis discharge; may experience moderate pain requiring analgesia) oral mucositis using the Radiation Therapy Oncology Group (RTOG) Acute Radiation Morbidity Scoring Criteria Oral Mucosa Assessment Scale at baseline and during radiotherapy will be recorded. The RTOG grading is reliant on a clinician's ability to judge the anatomical changes associated with oral mucositis (size and characteristics of ulceration), with symptoms ranging from Grade 0 (no symptoms) to Grade 4 (Ulceration, hemorrhage, or necrosis). A comparison of incidence in the GM-CSF Group (GG) and Arm II: Salt \& Soda Group (SS) will be reported.

Time frame: From baseline to onset of mucositis, approximately 16 days

Comparison of the Mean Number of Days for Mucositis to Heal Across by Group

The mean number of days for mucositis to heal will be used to evaluate the effectiveness of the two mouthwashes in treating oral mucositis as defined by the incidence of Radiation Therapy Oncology Group Acute Radiation Morbidity Scoring.

Time frame: From onset of mucositis to healing of mucositis, approximately 80 days

Secondary Outcomes

Comparison of the Combined Mean Score on the Overall Quality of Life Questionnaires by Group

Quality of life at baseline, during radiotherapy, and once a month for 3 months after radiotherapy. The items on the quality of life questionnaire developed for the study range in scores from 0-10 with higher scores indicating a better quality of life. Scores at all time points were combined to compute one mean score for overall quality of life during the study.

Time frame: Up to 3 months

Comparison of Combined Mean Score on the Karnofsky Performance Status Scale (KPS) by Group

Functional status of participants was measured by administering the KPS which contains items asking about performing daily activities. The scores are grouped in 10s ranging from 100 (Normal, no complaints) to 0 (Dead), with higher scores indicating better functional status. The KPS was administered at baseline, during radiotherapy, and once a month for 3 months after radiation therapy. Scores at all time points were combined to compute one mean to determine overall performance status during the course of the study.
