Study summary

This is a single-center randomized controlled trial of a new medical device (Bocaliner™) that has been designed to improve the treatment of chemotherapy-induced oral mucositis in patients undergoing cancer treatment. The goal of this study is to determine tolerance and response to the use of Bocaliner™ as reported by patients with chemotherapy and/or radiation therapy-induced oral mucositis.

Read the detailed description

All patients will be referred by their treating physicians to the designated study healthcare providers. Patients will have been diagnosed with oral mucositis and will be receiving oral topical medication for oral pain as well as other problems related to oral mucositis. All subjects will sign an informed consent form.

Initially, subjects will undergo an oral examination and for determination of the World Health Organization (WHO) Oral Toxicity Scale and will then complete a General Oral Mucositis Assessment Scale.

Subjects will then be randomized into two groups. Group 1 will continue standard therapy with oral topical agents for oral mucositis. Group 2 will additionally receive Bocaliner™ devices along with cleaning materials with instructions about device use and cleaning. Subjects in the Group 2 will use Bocaliner™ with each topical treatment for oral mucositis up to 5 times per day for 2 weeks or shorter if not tolerated.

Subjects assigned to the Group 1 will continue the original therapy for oral mucositis, including oral topical treatments and general hygiene measures. Participants that are randomized to the Group 2 will place Bocaliner™ inside of their mouth for 5 minutes and fill out the Initial Bocaliner™ Questionnaire. They will then continue all original therapy for oral mucositis, including oral topical treatments and general hygiene, and will place the Bocaliner™ device inside of their mouth and hold it in place up to 40 minutes as instructed after each topical treatment.

All subjects will be contacted by the Research Coordinator via phone call at 5 and 10 days after the initial enrollment and invited to answer the questions from the Modified PROMS Questionnaire at the hospital. Alternatively, the questionnaire can be provided via email, or the questions can be answered via phone call, if preferred by a patient. Subjects in Group 2 will describe their experience of using Bocaliner™ through the Bocaliner™ Follow-up Questionnaire. All subjects will give a detailed description of their current medication usage for oral mucositis. Participants from both groups will return to their practitioners after 14 days and undergo a general oral examination. The WHO Oral Toxicity Scale will be used to assess the grade of oral mucositis. Subjects will also complete the Modified PROMS Questionnaire at days 5, 10, and 14 to understand the impact of standard treatment vs Bocaliner™ on symptoms related to oral mucositis.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

    Standard Therapy

    Subjects will then be randomized into two groups. The Standard Therapy Group will continue their usual therapy with oral topical agents for oral mucositis.

    Device: Bocaliner

  • Experimental
    Bocaliner

    Participants that are randomized to the Bocaliner Group will place Bocaliner™ inside of their mouth for 5 minutes and fill out the Initial Bocaliner™ Questionnaire. They will then continue all original therapy for oral mucositis, including oral topical treatments and general hygiene, and will place the Bocaliner™ device inside of their mouth and hold it in place up to 40 minutes as instructed after each topical treatment.

    Device: Bocaliner

Interventions

  • DeviceBocaliner

    Bocaliner is an orally inserted device that is held within the mouth following the administration of mouthwashes, gels, and rinses that are used to treat pain associated with oral mucositis, and to reduce inflammation and to accelerate healing of oral mucositis.

    Also known as: Standard Treatments for Oral Mucositis

What researchers measure

Primary outcomes

  1. Change in Patient-Reported Oral Mucositis Symptom (The Modified PROMS Questionnaire) Pain Score

    The modified PROMS score is designed to measure symptoms and quality of life in patients with oral mucositis. It consists of twelve questions. The range in scores for each section is 0 to 100. Higher scores on the Modified PROMS indicate worse outcomes. The range in the Pain Score of the Modified PROMS Questionnaire is from 0 to 100.

    Time frame: 5, 10, and 14 days

Secondary outcomes

  1. Change in other symptoms of oral mucositis on the Patient-Reported Oral Mucositis Symptom (The Modified PROMS Questionnaire.

    The modified PROMS score is designed to measure symptoms and quality of life in patients with oral mucositis. It consists of twelve questions. The range in scores for each question is 0 to 100. Higher scores on the PROMS Questionnaire indicate worse outcomes.

    Time frame: 5, 10, and 14 days

  2. Change of oral mucositis grade in the World Health Organization Grade,(WHO Mucositis Grade)

    The WHO Mucositis grade is based on the appearance of the oral mucosa and the effect of oral mucositis on nutritional intake. The range of grades is from 1 to 4. Higher WHO Mucositis grades indicate worse outcomes.

    Time frame: 5, 10, and 14 days

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
