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

Launched by UNIVERSITY OF NORTH CAROLINA, CHAPEL HILL · Nov 27, 2023

ClinConnect Summary

This clinical trial is investigating the effects of a medication called baricitinib in patients with a condition known as Oral Lichen Planus, which can cause painful sores in the mouth. The study aims to find out how well baricitinib works for treating moderate to severe cases of this condition, how it might improve the quality of life for patients, and what side effects participants may experience while taking the medication.

To be eligible for this trial, participants must be at least 18 years old and have a confirmed diagnosis of Oral Lichen Planus that is moderate to severe. They should have already tried at least one other treatment without success. Throughout the study, participants will visit the clinic once a month for up to eight months, where they will receive baricitinib to take home for six months. During these visits, they will be assessed for their condition and asked about their quality of life, along with monitoring for any side effects from the treatment. It's also important for participants to maintain good oral hygiene during the study and avoid certain products. This trial is currently recruiting participants, and it’s a chance to help improve treatment options for this condition.

• • 5. Fasting cholesterol levels \>400mg/dL or \>10.34mmol/L within 30 days of starting study drug or levels that may have required hospitalization, caused pancreatitis, or became life threatening.
• • 6. Serum triglycerides \>500mg/dL or \>5.7mmol/L within 30 days of starting study drug.
• • 7. Chronic liver disease with severe hepatic impairment as defined in the protocol.
• • 8. Inadequate renal function tests defined as an estimated glomerular filtration rate (eGFR) based on the most recent available creatinine using the chronic kidney disease epidemiology collaboration equation (CKD-EPI) creatinine 2009 equation of \<60 millimeters/minute/1.73 meters squared (m\^2) within 30 days of starting study drug.
• • 9. Ongoing active or recent clinically serious fungal, bacterial, viral, or parasitic infection.
• • 10. History of gastrointestinal perforation
• • 11. History of heart attack or significant cardiovascular risk that in the investigator's judgement, the risks of the subject participating in the study is greater than its benefit.
• • 12. Hypercoagulable state such as history of deep vein thromboembolism (VTE) or stroke OR are considered at high risk of VTE.
• 13. History of cancer (except treated cutaneous basal cell carcinoma (BCC), cutaneous squamous cell carcinoma in situ (cSCCis) and in situ cervical cancer) unless it can be documented that the patient has been in a disease-free state for at least 5 years for high grade cancers with the following exception:
• • In case of clinical suspicion of malignancy in the oral cavity, a patient can only be included after an excluding biopsy
• • Any history of squamous cell carcinoma or melanoma (even if resected) in the mouth, as well as history of other non-squamous cell carcinoma (e.g., sarcoma, salivary gland tumors) in the mouth are excluded.

• • 15. Professional dental cleaning within 2 weeks prior to baseline
• • 16. Patient with any un-healed oral surgery (including recent diagnostic biopsies, if applicable) or oral laser therapeutic wound(s) at baseline visit
• • 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 or otherwise interfere with study participation or require active frequent monitoring (e.g., unstable chronic asthma)

• • 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.
