NCT03602066

Brief Summary

This pilot randomized phase II trial studies who well chlorine dioxide sterilization works in reducing oral mucositis in patients with stage I-IV head and neck cancer who are undergoing radiotherapy. Chlorine dioxide sterilization may help to treat oral mucositis.

Outcome Measures

Primary Outcomes (1)

  • Incidence of Severe Oral Mucositis (OM) (>= World Health Organization [WHO] Mucositis Scale Grade 3)

    Will be compared between arms. Analysis will be performed by estimating the proportion with exact 95% binomial confidence interval for each group separately. Statistical testing will use a chi-square test. As an alternative, Fisher?s Exact Test will be used if the minimum expected value is \< 5. WHO Scale: Grade 0 (none) - None; Grade I (mild) - Oral soreness, erythema; Grade II (moderate) - Oral erythema, ulcers, solid diet tolerated; Grade III (severe) - Oral ulcers, liquid diet only; Grade IV (life-threatening) - Oral alimentation impossible. No grade 3 or higher Oral Mucositis was reported on either treatment arm, so no differences were observed.

    Up to 30 days post radiotherapy

Secondary Outcomes (4)

  • Time to Onset of Severe OM (>= World Health Organization [WHO] Mucositis Scale Grade 3)

    Up to 30 days post radiotherapy

  • Duration of Severe OM (>= World Health Organization [WHO] Mucositis Scale Grade 3)

    Up to 30 days post radiotherapy

  • Patient Reported Outcomes as Measured by the Oral Mucositis Weekly Questionnaire (OMWQ)

    Up to 30 days post radiotherapy

  • Rates of Radiotherapy Interruption

    Up to 30 days post radiotherapy

Other Outcomes (2)

  • Oral Microbiome

    Up to 30 days post radiotherapy

  • Salivary TNFalpha, IL-1beta, and IL-6 Levels

    Up to 30 days post radiotherapy

Study Arms (2)

Arm I (chlorine dioxide sterilization)

EXPERIMENTAL

Patients receive chlorine dioxide sterilization oral rinse over 30 seconds BID from the start of RT to the evening prior to the 1 month RT follow-up appointment.

Drug: Chlorine Dioxide SterilizationOther: Laboratory Biomarker Analysis

Arm II (placebo)

PLACEBO COMPARATOR

Patients receive placebo oral rinse over 30 seconds BID from the start of RT to the evening prior to the 1 month RT follow-up appointment.

Other: Laboratory Biomarker AnalysisOther: Placebo

Limitations and Caveats

This study stopped accrual early as the IP manufacturer terminated the study stopping funding and IP. 14 out of 20 subjects were accrued, 11 of which completed study. Due to early termination with few patients, only the counts of events have been calculated and no testing was done.
