Trial Summary

What is the purpose of this trial?

This trial is testing baricitinib, a drug that might help people with painful mouth sores from Oral Lichen Planus. It aims to see if the drug can improve their condition and quality of life, and what side effects it might have. Participants will take the drug for several months and visit the clinic regularly for evaluations. Baricitinib has been evaluated for other conditions and has shown potential as a treatment.

Do I have to stop taking my current medications for this trial?

The trial protocol does not specify if you must stop taking your current medications. However, it mentions that participants must have failed at least one systemic therapy for Oral Lichen Planus and should follow appropriate washout for past medications. It's best to discuss your specific medications with the trial team.

What data supports the idea that Baricitinib for Oral Lichen Planus is an effective treatment?

The available research does not provide specific data on the effectiveness of Baricitinib for treating Oral Lichen Planus. Instead, it focuses on other aspects of the condition or alternative treatments like curcumin. Therefore, there is no direct evidence from the provided information to support the effectiveness of Baricitinib for this condition. ^{1 2 3 4 5}

What safety data exists for Baricitinib in treating oral lichen planus?

The provided research does not contain specific safety data for Baricitinib (Olumiant, LY3009104) in the treatment of oral lichen planus. The studies focus on disease severity scoring systems, tacrolimus treatment, and the association between drug intake and oral lichen planus, but do not address Baricitinib. ^{6 7 8 9 10}

Is the drug Baricitinib a promising treatment for Oral Lichen Planus?

Baricitinib, a drug that blocks certain signals in the body, has shown promise in treating conditions similar to Oral Lichen Planus by reducing inflammation. It has been effective in treating other inflammatory conditions, suggesting it could be a promising option for Oral Lichen Planus as well. ^{11 12 13 14 15}

Findings from Research

In a study of 14 oral lichen planus (LP) biopsy specimens compared to matched controls, there was a significant increase in the expression of key adhesion molecules, indicating a compensatory response by keratinocytes to resist damage and prevent ulceration.

The intense expression of integrins and basement membrane proteins suggests that these changes may aid in epithelial migration and wound repair, while also indicating recent remodeling of the epithelial structure in LP.

The study found that vascular endothelial growth factor (VEGF) levels were significantly higher in patients with oral lichen planus (OLP) compared to healthy controls, indicating a potential role in the disease's pathogenesis.

In atrophic/erosive OLP (A/ELP), there was a strong positive correlation between VEGF and matrix metalloproteinase-2 (MMP-2) in connective tissue, suggesting that these proteins may be involved in the malignant transformation of OLP lesions.

A systematic review identified 11 clinical severity scoring systems for oral lichen planus that have been validated for reliability, with the Thongprasom score, Oral Disease Severity Score (ODSS), and REU scoring systems being the most commonly reported.

Despite the validation of these scoring systems for oral lichen planus, there is a significant gap in standardized scoring systems for extraoral mucosal lichen planus, highlighting the need for further development and testing in this area.

Tacrolimus mouth rinse was found to be effective in reducing symptoms of erosive and ulcerative oral lichen planus (OLP), showing significant improvement in REU scores compared to dexamethasone after 4 weeks of treatment.

Although the overall effective rate was similar between tacrolimus and dexamethasone at 4 and 12 weeks, tacrolimus demonstrated quicker effects, suggesting it could be a valuable treatment option for OLP.

In a study of 110 patients with oral lichen planus (OLP) and 76 control subjects, daily systemic medication did not significantly increase the incidence of OLP lesions, suggesting that medication use is not a major contributing factor to the development of these lesions.

Lichenoid drug reactions (DILRs) were found to occur in a very low percentage of patients, with the erosive form of OLP being more common in non-medicated individuals, indicating that medication-related reactions are relatively rare.

The study analyzed 11 hospitals and included patients with oral lichen planus (OLP), finding that the average age of patients was 49.2 years, with a majority being women (61.4%).

Key risk factors for developing erosive/ulcerative OLP included older age, a disease duration of 12 months or more, dental calculus, hypertension, diabetes, and heart disease, indicating that these factors may help identify patients at higher risk.

Topical tacrolimus was not found to be more effective or safer than topical corticosteroids for treating erosive oral lichen planus, based on a meta-analysis of 9 randomized controlled trials involving 476 patients.

No serious adverse events were reported with topical tacrolimus, suggesting it is safe for use, but the overall efficacy compared to corticosteroids remains inconclusive.

In a phase II study involving 12 patients, topical ruxolitinib significantly reduced the total lesion count in cutaneous lichen planus by a median of 50 lesions after 8 weeks of treatment, indicating its efficacy.

Transcriptomic analysis revealed that cutaneous lichen planus is driven by interferon pathways, and the treatment with ruxolitinib led to downregulation of interferon-stimulated genes, supporting its mechanism of action in targeting this disease.

Janus kinase (JAK) inhibitors, such as upadacitinib, tofacitinib, and baricitinib, have shown promising safety and efficacy in treating various forms of lichen planus (LP), particularly lichen planopilaris, nail LP, and erosive LP, based on multiple case reports and series.

The INF-γ/CXCL10 signaling pathway is implicated in the chronic inflammation of LP, suggesting that targeting JAKs could be a beneficial therapeutic strategy, warranting further clinical trials to evaluate their effectiveness in larger populations.
