  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: Triple (Participant, Investigator, Outcomes Assessor)
  • Study Primary Completion Date: June 1, 2020

Detailed Description

Matrix metalloproteinases inhibitor (Orochem) will be given to patients with Oral erosive lichen planus three times daily for 3 weeks. Then the subjective discomfort and pain severity as well as the objective disease severity scores will be collected.


  • Drug: Matrix Metalloproteinase Inhibitors (Orochem)
    • topical application of MMP inhibitors for 3 weeks to evaluate its effectiveness in treating oral lichen planus
  • Drug: Kenacort A,
    • topical application of both drugs 3 times daily for 3 weeks as an active control

Arms, Groups and Cohorts

  • Experimental: Orochem (Test)
    • fifteen patients with lichen planus will be treated with MMPs neutralizing agent 3 times daily for 3 weeks. then pain, discomfort and disease severity will be assessed at 1 and 3 weeks periods.
  • Active Comparator: Conventional (Control)
    • fifteen patients with oral lichen planus confirmed with a biopsy will be treated with topical corticosteroids, topical antifungal 3 timed daily for 3 weeks. then pain, discomfort and disease severity will be assessed at 1 and 3 weeks periods.
