Inclusion Criteria:

• OLP patients with at least one visible and measurable symptomatic ulcerative OLP lesion, assessable via OLP Clinician Reported Outcome Measure (OLPClinROM).
• Diagnosis of LP histologically confirmed by result of either an existing clinically relevant biopsi or a new clinically representative biopsy at first screening visit (i.e. a biopsy report either indicative of OLP, LP or indicative of lichenoid inflammation will be sufficient).
• Patients aged ≥ 18 years.
• Patients practicing daily oral hygiene (by tooth brushing and/or mouth rinse) and willing to maintain at least their routine oral hygiene procedure during study participation.
• Willingness to keep already used permitted concomitant medication, food supplements (e.g. probiotics) or herbals, which might have in the discretion of the investigator a potential influence on OLP, on a stable basis during the study.

Exclusion Criteria:

• Patients requiring more than 6 patches (corresponding to an area of approximately 3 cm2 per patch) to cover symptomatic ulcerative and erythematous OLP lesions at baseline visit.
• Ongoing active visible fungal, bacterial or viral infection of oral mucosa, including ongoing treatment of those at baseline.
• Patient with any un-healed oral surgery (including recent diagnostic biopsies, if applicable) or oral laser therapeutic wound(s) at baseline visit.

• Any of the following systemic treatments prior to baseline visit and throughout the study:

  • Protease inhibitors used for the treatment of HIV (e.g. atazanavir, idinavir, nelfinavir, etc.): 1 week
  • Corticosteroids (i.v., intra articular, intra-lesional): 4 weeks
  • Antimycotics: 4 weeks The following systemic treatments are allowed, if on stable dose for a defined period of time to baseline and throughout the study.
  • Antibiotics: 4 weeks
  • Corticosteroids (oral, rectal, inhalative) washout/stable with maxinum dose of 10 mg daily prednisolone or equivalent for 4 weeks.
  • Retinoids: 12 weeks
  • Immunosuppressive drugs (e.g. azathioprine, cyclosporine, mycophenolate mofetil, or biologics): 12 weeks

• Any of the following topical treatments used in the oral cavity prior to baseline visit:

  • Corticosteroids: 2 weeks
  • Antibiotics: 2 weeks
  • Cyclosporine: 2 weeks
  • Tacrolimus, pimecrolimus: 2 weeks
  • Antimycotics: 2 weeks
  • Retinoids: 4 weeks
• Phototherapy in oral cavity prior to baseline visit: UVB, PUVA.
• Current participation in another clinical study and/or having received treatment with any non-marketed / investigational medicinal product (drug substance or medical device) within 4 weeks prior to screening.
• Known or suspected intolerance/hypersensitivity/resistance to clobetasol propionate or any component of the investigational medicinal product.
• Any history of squamous cell carcinoma (even if resected), as well as history of other non-squamous cell carcinoma (e.g. sarcoma, salivary gland tumors) that have been managed with radiation or chemotherapy.
• History of cancer (except resected cutaneous basal cell carcinoma and except in situ cervical cancer) unless it can be documented that the patient has been in a disease-free state for at least 5 years, or at least 2 years in a disease-free state for low-grade cancers. In case of clinical suspicion of malignancy in the oral cavity, a patient can only be included after an excluding biopsy.
• Professional dental cleaning within 2 weeks prior to baseline and unwillingness to refrain from professional dental cleaning during study conduct.
• Close affiliation with the investigator (e.g. a close relative) or persons working at the study sites or patient who is an employee of the Sponsor's company.
