Efficacy and Safety of add-on Apremilast Versus add-on Methotrexate in Patients With Oral Lichen Planus

India64 participantsStarted 2024-01-26

Plain-language summary

Lichen planus is an inflammatory disorder of unknown aetiology affecting the stratified squamous epithelia, with an estimated global prevalence of 0.22 to 0.5 %. Oral mucosa (Oral Lichen Planus; OLP) is the most commonly affected region. Corticosteroids are the primary treatment of choice. A prolonged treatment with steroids is required for clinical improvement, which increases the chances of long-term adverse effects. So, there is a need for newer, effective treatment modalities, such as retinoids, methotrexate, Janus kinase inhibitors, PDE4 inhibitors, etc. Of these, methotrexate is a dihydrofolate reductase inhibitor that inhibits the replication and function of T and B lymphocytes. It has shown a good response to OLP (around 83%) in a study by Lajevardi et al. and can be considered a treatment option in patients with moderate to severe OLP. Apremilast is a drug with a novel immunomodulatory mechanism of action. It inhibits phosphodiesterase type IV, which increases levels of cyclic adenosine monophosphate (cAMP), thus activating protein kinase A and inhibiting various inflammatory mediators. Based on a pilot study by Paul et al., apremilast is associated with clinical improvement in lichen planus. Among the various treatment options, there is a lack of head-on trials. Methotrexate is an immunosuppressant with various systemic adverse effects and requires close monitoring. Whereas apremilast is a non-immunosuppressive drug with a better safety profile, it does not show such adverse effects. These drugs can be used as an add-on to low-dose steroids in view of reducing the adverse effects associated with steroid therapy. To the best of our knowledge, there is no randomized controlled trial comparing these two drugs to date. Hence, the present study has been planned to evaluate the safety and efficacy of methotrexate versus apremilast as an add-on to the standard steroid therapy in OLP patients.
