Study of Topical Superoxide Dismutase to Treat Radiation Induced Fibrosis (Sodermix)

This study has been completed.
Information provided by (Responsible Party):
Sanford Health Identifier:
First received: January 11, 2013
Last updated: January 11, 2017
Last verified: January 2017
The purpose of this study is to determine if topical superoxide dismutase is an effective treatment of radiation related neck fibrosis, and to determine the quality of life impact from radiation related fibrosis in the head and neck cancer patients at Sanford Health.

Condition Intervention
Radiation Induced Fibrosis to the Head and Neck Drug: Topical Sodermix Dismutase in the form of Sodermix (SOD) Drug: Placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: Topical Superoxide Dismutase For the Treatment of Radiation Induced Fibrosis in the Head and Neck Cancer Patient

Primary Outcome Measures:
  • Improvement in Neck Fibrosis [ Time Frame: 3 months ]
    Number of participants with improvement in fibrosis as defined as a one point improvement on the fibrosis scale using the grading scale outlined in CTCAE 4.03, page 46.

Secondary Outcome Measures:
  • Determine the Quality of Life Impact From Radiation Related Fibrosis in Head and Neck Cancer Patients [ Time Frame: 3 months ]
    Metrics are measured via analysis of pain and range of motion and Health Related Quality of Life questionnaire.

Enrollment: 74
Study Start Date: August 2012
Study Completion Date: June 2013
Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Topical Sodermix Dismutase
Patients with measurable radiation induced fibrosis of the neck. Patients will be randomized to applying Topical Sodermix Dismutase in the form of Sodermix(SOD) to the area of neck skin fibrosis twice a day for 12 weeks.
Drug: Topical Sodermix Dismutase in the form of Sodermix (SOD)
Topical Sodermix Dismutase in the form of Sodermix (SOD) will be applied twice daily, of half dollar application for 12 weeks to fibrosed area.
Other Names:
  • Sodermix
  • SOD
Placebo Comparator: Placebo group
Cetaphil cream
Drug: Placebo
Placebo or cetaphil cream will be applied twice daily, of half dollar size for 12 weeks to fibrosed area.
Other Name: Cetaphil cream

Detailed Description:

The primary goal of this study is to evaluate the effect of topical Superoxide Dismutase (SOD) on the radiation induced fibrosis in head and neck cancer patients. A prospective, blinded, two group control design will be used with pretest and post test quality of life as well as objective fibrosis assessment. Patients will be randomized to alternatively receive topical SOD or placebo as instructed on twice daily use for 3 months. Pre and post treatment quality of life surveys and objective assessment will determine if the topical SOD improves neck fibrosis/function and global quality of life.

This study will increase clinical trial awareness and participation while potentially improving the long term functional outcomes of head and neck cancer patients.
