Basic Information

• Recruitment Status: COMPLETED

• Total Enrollment: 40 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2003-10-31

Brief Summary

The purpose of this study is to explore the protective effect and safety of soluble beta-1,3/1,6-glucan compared to placebo in oral mucositis in head and neck patients receiving radiotherapy or chemoradiotherapy.

Hypothesis: Soluble beta-1,3/1,6-glucan will through its immunomodulating activities prevent oral mucositis

Detailed Description

Oral mucositis is defined as inflammation and ulceration of the mucous membranes of the mouth. The condition is very painful and might put the patient at risk of serious systemic infections and is a common dose-limiting toxicity of chemotherapy and radiotherapy. The present treatment of mucositis is primarily supportive; strong analgesics in addition to oral hygiene. Prophylactic antibiotics have been used and many topical agents are available to palliate mucositis, but no standard therapy has been accepted.

Comparison: Methyl cellulose has been chosen as placebo due to its close resemblance to soluble beta-1,3/1,6-glucan in terms of general appearance and viscosity. Methyl cellulose is a viscous solution which might form a mucosal barrier. Physical barriers are considered having a protective function in oral mucositis, and methyl cellulose might be considered as an active control.

Exclusion Criteria

• Patients who will receive hyperfractionated or accelerated radiotherapy
• History of malignancies within the past five years other than non-melanomatous skin cancers (with the exception of squamous cell carcinoma of the skin) or carcinoma in situ of the cervix
• Previous neoplasm in the head and neck area, whether malignant or not
• Previous radiation therapy for head and neck cancer
• If wound from curative surgery have not healed
• Patients expected to receive agents that would interfere with the investigator's ability to assess changes in the appearance of the mucositis during the study
• Use of radiosensitizers
• History or clinical evidence of active significant acute or chronic diseases that may compromise the ability to evaluate or interpret the effects of the study treatment on mucositis

• Total bilirubin >= 36 micromol/L, AST > 3 times the upper normal limit
• Any subject who, in the opinion of the investigator, is unlikely to comply with the study procedures, or is unlikely to complete the study due to different reasons like e.g. language barriers or mental incapacity
• Participation in a clinical trial in the last 30 days Receipt of any investigational product within 30 days prior to this trial

• Minimum Eligible Age: 18 Years
