Efficacy and Safety of Baricitinib in Oral Lichen Planus: a Proof-of-Concept Study

Phase 2

Recruiting

• Conditions: Lichen Planus, Mucosal; Lichen Planus, Oral; Oral Lichen Planus
• Interventions: Drug: Baricitinib 4 milligram Oral Tablet

• Registration Number: NCT06158113
• Lead Sponsor: University of North Carolina, Chapel Hill

Brief Summary

The goal of this clinical trial is to learn the effects of baricitinib (the study drug) in patients with Oral Lichen Planus. The main questions it aims to answer are:

* What is the efficacy of baricitinib in treating moderate to severe Oral Lichen Planus?

* Can baricitinib treatment in Oral Lichen Planus change quality of life?

* What side effects do patients with Oral Lichen Planus experience when treated with baricitinib?

Participants will be required to come in to monthly visits for up to eight months. During visits, participants will be:

* Evaluated for the extent of their disease

* Asked to fill out a questionnaire about their quality of life

* Given baricitinib for them to take at home for six months

* Evaluated for any potential side experienced while on treatment

* Asked to return 1 month after completing treatment

• Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
Baricitinib	Baricitinib 4 milligram Oral Tablet	Participants will be asked to take 4mg of baricitinib by mouth daily for up to 24 weeks.

Primary Outcome Measures

Name	Time	Method
Change in Oral Disease Severity Scale (ODSS) Scores	Baseline, 24 weeks	The Oral Disease Severity Scale (ODSS) is a validated tool to assess severity of Oral Lichen Planus. For scoring, the oral cavity is divided into 17 sites and assigned three different scores. A site score, which captures disease extent, a severity score, and an activity score which is obtained by multiplying the site and severity scores. Independently study participants are asked to fill in a numerical rating scale graded from 0-10, with zero meaning no pain and 10 being the worst imaginable pain felt within the last 4 weeks. Scores are added together and range from 0-106, with higher scores meaning more severe disease. Overall change from baseline to week 24 will be reported.

Secondary Outcome Measures

Name	Time	Method
Changes in Quality of Life as assessed with the Chronic Oral Mucosal Disease Questionnaire-26 (COMDQ-26).	Baseline, 24 weeks	The Chronic Oral Mucosal Disease Questionnaire-26 (COMDQ-26) is a 26-item validated survey specific to assess changes in quality of life in patients with Oral Lichen Planus. The total score of the COMDQ-26 ranges from 0-104 with higher scores indicating worse quality of life. The number of participants that achieve at least a 9 point reduction in their scores from baseline will be reported.
