About this study

Official title: Oral Topical Cyclooxygenase Inhibitor (Aspirin) Mouthwash for Treatment of Oral Dysplasia

RATIONALE: Aspirin mouthwash may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PURPOSE: This phase I trial is studying the side effects and best dose of aspirin mouthwash in treating patients with oral leukoplakia.

Read the detailed description

OBJECTIVES:

  • To determine if oral topical acetylsalicylic acid mouthwash achieves modulation of COX-1, COX-2, and prostaglandin in oral dysplasia tissues in patients with oral leukoplakia.
  • To determine if this drug achieves alteration of histopathology and gene and protein expression in tissue.
  • To determine if this drug achieves aspirin-induced tissue changes relating to altered tumor biology.
  • To assess local and general tolerability and safety of this drug in these patients.

OUTLINE: All patients undergo tissue biopsy for histological diagnosis. Patients without a histological diagnosis of precancerous oral dysplasia undergo routine follow-up. Patients with a histological diagnosis of precancerous oral dysplasia are sequentially allocated to 1 of 4 treatment groups.

  • Group 1: Patients receive acetylsalicylic acid mouthwash (one 75 mg tablet dissolved in 250 mL of water) twice daily for 4-6 weeks, gargling for 60 seconds then expectorate it fully, before planned definitive surgical excision.
  • Group 2: Patients receive acetylsalicylic acid mouthwash (two 75 mg tablets of acetylsalicylic acid dissolved in 250 mL of water) twice daily for 4-6 weeks, gargling for 60 seconds then expectorate it fully, before planned definitive surgical excision.
  • Group 3: Patients receive acetylsalicylic acid mouthwash (one 300 mg tablet of acetylsalicylic acid dissolved in 250 mL of water) twice daily for 4-6 weeks, gargling for 60 seconds then expectorate it fully, before planned definitive surgical excision.
  • Group 4: Patients receive acetylsalicylic acid mouthwash (one 300 mg tablet of acetylsalicylic acid dissolved in 250 mL of water) three times daily for 4-6 weeks, gargling for 60 seconds then expectorate it fully, before planned definitive surgical excision.

At the time of definitive surgical excision, the patient is asked to gargle with the last dose of acetylsalicylic acid mouthwash just before being anesthetized. A small biopsy of the dysplasia lesion is taken and examined for immediate effects of the acetylsalicylic acid mouthwash on the dysplasia lesion. The surgically excised tissue is treated in the same way as the initial biopsy tissue (i.e., half being used for routine histology to confirm the diagnosis and the other half for research purposes). Tissue samples are analyzed via enzyme immunosorbent assay, qRT-PCR, immunoblotting, ELISA, immunohistochemistry, gene array analysis, and microvessel density analysis.

Patients complete a questionnaire assessing local and general tolerability as well as adverse effects during the period of use of the mouthwash.

After completion of study treatment, patients are followed periodically.

What is being measured

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

  1. PGE2 levels as assessed by enzyme immunosorbent assay

  2. COX-1 and COX-2 mRNA as assessed by qRT-PCR

  3. COX-1 and COX-2 protein expression as assessed by immunohistochemistry and quantified by immunoblotting to determine whether COX inhibition in oral dysplasia tissues is actually possible by use of the mouthwash formulation

Secondary outcomes (5)
  1. Comparison of WHO histological grade and clinical size of dysplastic lesions before and after treatment and assessment of proliferating cell nuclear antigen

  2. Tolerability and possible oral and other adverse effects using a questionnaire

  3. VEGF mRNA expression as assessed by qRT-PCR

  4. Protein expression as assessed by ELISA and immunohistochemistry for VEGFA

  5. Global gene response of dysplastic tissue as assessed by Affymetrix gene expression microarrays

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing acetylsalicylic acid, gene expression analysis and protein expression analysis in people with Precancerous Condition, run by Institute of Head and Neck Studies and Education, United Kingdom at 2 sites in United Kingdom.

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

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Aug 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United Kingdom. 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

PGE2 levels as assessed by enzyme immunosorbent assay. The study lists 3 primary outcomes in all. 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 12 Aug 2013.
