About this study

Official title: A Pilot Phase II Study Evaluating the Role of Chlorine Dioxide on Mucositis for Patients Undergoing Head and Neck Radiotherapy

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.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To evaluate and compare CloSYS Unflavored Oral Rinse effect on the incidence of severe oral oral mucositis (OM) (>= World Health Organization [WHO] grade 3).

SECONDARY OBJECTIVES:

  1. To evaluate and compare CloSYS Unflavored Oral Rinse effect on the time to onset of severe OM (>= WHO grade 3).

II. To evaluate and compare CloSYS Unflavored Oral Rinse effect on the duration of severe OM (>= WHO grade 3).

III. To evaluate and compare CloSYS Unflavored Oral Rinse effect in patient reported outcomes as measured by the Oral Mucositis Weekly Questionnaire (OMWQ).

IV. To evaluate and compare CloSYS Unflavored Oral Rinse effect on rates of radiation therapy (RT) interruption.

  1. To evaluate and compare CloSYS Unflavored Oral Rinse effect on the oral microbiome.

VI. To evaluate and compare CloSYS Unflavored Oral Rinse effect on salivary TNFalpha, IL-1beta, and IL-6 levels.

OUTLINE: Patients are randomized into 1 of 2 arms.

ARM I: Patients receive chlorine dioxide sterilization oral rinse over 30 seconds twice daily (BID) from the start of radiation therapy (RT) to the evening prior to the 1 month RT follow-up appointment.

ARM II: 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.

After completion of study, patients are followed up on day 1.

What is being measured

The primary outcome is the main question the study is designed to answer.

  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.

    Measured: Up to 30 days post radiotherapy

Secondary outcomes (4)
  1. Time to Onset of Severe OM (>= World Health Organization [WHO] Mucositis Scale Grade 3)

    Will be tabulated and the median week to onset will be computed for each group. Comparison will be performed using a Wilcoxon Rank Sum Test (as the values are unlikely to be normally distributed).

    Measured: Up to 30 days post radiotherapy

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

    will be tabulated and the median week to onset will be computed for each group. Comparison will be performed using a Wilcoxon Rank Sum Test (as the values are unlikely to be normally distributed).

    Measured: Up to 30 days post radiotherapy

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

    Will be compared between groups using a linear mixed-effects model to account for the correlation among the measurements within an individual.

    Measured: Up to 30 days post radiotherapy

  4. Rates of Radiotherapy Interruption

    Will be tabulated and compared using a chi-square test.

    Measured: Up to 30 days post radiotherapy

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Chlorine Dioxide Sterilization and Laboratory Biomarker Analysis in people with Head and Neck Carcinoma, run by University of Arizona at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 20 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Mar 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Severe Oral Mucositis (OM) (>= World Health Organization [WHO] Mucositis Scale Grade 3) (time frame: Up to 30 days post radiotherapy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2024.
