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

Primary Outcome Measures:
  • Efficacy of alitretinoin (Toctino®) based on the Escudier score of oral lesions at baseline and after 24 weeks of treatment. [ Time Frame: 6 months ]
    The primary objective is to determine the efficacy of alitretinoin (Toctino®) in reducing signs and symptoms of severe mucosal lichen planus with respect to the proportion of responders based on the, Escudier score of oral lesions at baseline and after 24 weeks of treatment or at the latest assessment for patients who withdrew prematurely (Last Observation Carried Forward, LOCF). Response is defined as a 50 % reduction in the total Escudier score compared to the baseline values.

Secondary Outcome Measures:
  • 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 OHIP [ Time Frame: 6 months ]
  • Assess the time to response (time to 50 % reduction in the total Escudier score) [ Time Frame: 6 months ]
  • Assess oral mucosal changes regarding inflammation and erosions, at treatment end compared to baseline using Escudier [ Time Frame: 6 months ]
  • Assess the number/distribution of extramucosal skin lesions (papules) of LP at treatment end compared to baseline [ Time Frame: 6 months ]
  • 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. [ Time Frame: 4 weeks ]
  • 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 [ Time Frame: 6 months ]
  • Assess safety of alitretinoin in mucosal lichen planus for the body as a whole [ Time Frame: 6 months ]

Estimated Enrollment: 20
