Condition(s) targeted: Lichen Planus (LP)
Intervention: alitretinoin (Drug)
Phase: Phase 2
Status: Recruiting

Summary
This is a single center, prospective, open label, single arm, investigator initiated pilot
study investigating the effect of alitretinoin on severe lichen planus with mucosal
manifestations. The target population comprises patients with MLP for at least 3 months,
with or without LP lesions on other areas of the skin, who are refractory to topical therapy
and standard skin care, and who are otherwise in good health. Patients will be recruited at
the outpatient clinic of the dermatology department, University hospital Zurich. The planned
duration of the study is 2 years. A total of 20 patients will be included. Patients who meet
enrolment criteria will receive 30mg alitretinoin, given orally as gelatin capsules, once
daily for 24 weeks. Dose interruptions are permitted in response to adverse effects,
consistent with use of retinoids and the product label.
Most clinical evaluations will be performed every 4 weeks. A safety follow-up visit is
planned 4 weeks after the end of treatment. Further follow-up visits will be conducted 16
and 24 weeks after end of treatment in those patients meeting the primary endpoint
- Trial with medicinal product
Clinical Details
Official title: Single-Center, Prospective, Open Label, Single-arm Pilot Study Investigating the Efficacy and Safety of Alitretinoin in Patients Suffering From Severe Mucosal Lichen Planus.
Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Primary outcome: Efficacy of alitretinoin (Toctino®) based on the Escudier score of oral lesions at baseline and after 24 weeks of treatment.
Secondary outcome: Assess the efficacy of alitretinoin over time in reduction of signs (e.g. ulcerations) or symptoms (e.g. pruritus), using VAS for pruritus and pain and OHIPAssess the time to response (time to 50 % reduction in the total Escudier score) Assess oral mucosal changes regarding inflammation and erosions, at treatment end compared to baseline using Escudier Assess the number/distribution of extramucosal skin lesions (papules) of LP at treatment end compared to baseline Assess, if applicable, the inflammatory infiltrate in mucosa and skin before and during alitretinoin therapy determined by histopathology taken before and 4 weeks after initiation of study treatment. Determine the relapse rate (relapse is defined as Escudier score or number of extramucosal papules increasing back to > 75% of baseline) within 24 week follow-up Assess safety of alitretinoin in mucosal lichen planus for the body as a whole
