Trial summary

Oral lichen planus is a common chronic mucocutaneous disease with various clinical forms. Erosive-ulcerative forms usually cause symptoms of pain and discomfort. The most important complication of OLP is development of oral squamous cell carcinoma, although this is a very controversial matter. Read more about this study

About this study

Oral lichen planus is a common chronic mucocutaneous disease with various clinical forms. Erosive-ulcerative forms usually cause symptoms of pain and discomfort. The most important complication of OLP is development of oral squamous cell carcinoma, although this is a very controversial matter. various treatments have been suggested for OLP but their results are unsatisfactory. Through the experiences of the investigators, corticosteroids (in any form)is not a wise option for treating OLP and has many side effects . More over, immunosuppressive therapy did not influence the risk for oral cancer. The purpose of the study is to determine the efficacy of free soft tissue graft in the treatment of precancerous and symptomatic lesions of OLP. Removal of the lesions up to submucosa has been done. The graft sliced from healthy mucosa also up to submucosa. Then graft will be sutured in position.

According to other authors, basal epithelial layers of the graft remain intact and represent the focus of re-epithelization. New epithelial cells migrate over the basal membrane and appear to guide it by proliferation, will generate new epithelium. The wound is re-epithelialized by proliferation of surrounding healthy epithelial cell, therefore, not contaminated by modified antigens of the cell membrane that are theoretically responsible for lymphocyte aggression. The healthy graft remains free of lesions and appears clinically healthy.

Read the detailed description

Oral lesions in OLP are chronic ,rarely undergo spontaneous remission, are potentially premalignant and are often a source of morbidity. recent study does not support that non reticular OLP are more predisposed to malignant change. Moreover , immunosuppressive therapy did not influence the risk for oral cancer. in general ,all treatment should be aimed at eliminating precancerous lesions ,alleviating symptoms ,and potentially decreasing the risk of malignant transformation. Although the cause of OLP is unknown , it is generally considered to be an immunologically mediated process that microscopically resembles a hypersensitivity reaction .it is characterized by an intense T cell infiltrate localized to epithelium-connective tissue interface. the purpose of the study is to determined the efficacy of free soft tissue graft in treatment of precancerous and symptomatic lesions of OLP. so removal of the lesions up to submucosa will be done. the graft sliced from healthy mucosa also up to submucosa . then graft will be sutured in position.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Surgical resectionProcedure or surgery

    Also called surgical resection of OLP

    20 patients with OLP will be selected for this study. Before this routine treatment modalities had been attempted. Removal of possible triggering drug was also considered. Local ethical committee approval will be obtained before the trial starts. Surgical procedure includes: removal of the tissue up to submucosa (containing antigenic properties that caused OLP). A specimen will be sent for histopathologic analysis. The graft sliced from healthy mucosa also up to submucosa. Then the graft trimmed on a gauze soaked in saline and adapted to recipient site. The graft was sutured in position. Checking will be done after 1 week and every two months up to 1 year. Punch biopsy will be done in 1 year after surgery for histopathologic investigations.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Surgical resection in people with Oral Lichen Planus, run by Qazvin University Of Medical Sciences at 1 site in Iran.

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 8 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 11 Dec 2008. 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 Iran. 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?

Results are not available in the source record.

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

Contact Farshid - Rayati, DDS (farshidrayati@yahoo.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Relief of sign & symptoms (every 2 month up to 1 years) (time frame: 1 year). 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 11 Dec 2008.
