Clinical Trial 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

17. Subjects must have failed at least one systemic therapy for OLP to be included in the study. Appropriate washout for past medications received and stable doses for other medications should be followed as outlined in the protocol.

18. Hypersensitivity to Janus kinase (JAK) inhibitors.

19. Subjects with any serious concomitant illness that is anticipated to require the use of systemic corticosteroids >10mg daily or otherwise interfere with study participation or require active frequent monitoring (e.g., unstable chronic asthma)

20. Subjects who require major surgery within 8 weeks of baseline and/or during the study are excluded.

21. Current participation in another clinical study and/or having received treatment with any non-marketed / investigational medicinal product (drug substance or medical device) within 30 days prior to baseline or 5.5 half-lives, whichever is longer.

22. Intention to become pregnant during the study period (30 days after stopping investigational product)

23. Intention to breastfeed until 30 days after stopping investigational product.

24. Any other condition that in the investigator's judgement the subject's risks are greater than the benefit from participating in the study or may interfere with interpretation of data.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Estimated response to 24 weeks of treatment with 4mg of baricitinib daily using the Investigator's Global Assessment (IGA).	The Investigator Global Assessment (IGA) represents the study doctor's overall assessment of the extent of disease. It assesses changes in symptomatic Oral Lichen Planus and it is meant to be a well-defined and reliable tool to measure disease severity in clinical studies. This tool assigns a score of 0-4 depending on how severe the disease is, with higher scores meaning worse disease. Overall change from baseline to week 24 reported.	Baseline, 24 weeks
Primary	Change in Oral Disease Severity Scale (ODSS) Scores	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.	Baseline, 24 weeks
Secondary	Changes in Quality of Life as assessed with the Chronic Oral Mucosal Disease Questionnaire-26 (COMDQ-26).	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.	Baseline, 24 weeks
