- Brief 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.

Group Intervention Description Prednisolone and Apremilast (Test Arm) Apremilast prednisolone 0.75mg/kg/day (a maximum dose of 30mg at baseline) and Apremilast 30 mg twice daily for 12 weeks. Prednisolone and Methotrexate (Control Arm) Prednisolone prednisolone 0.75mg/kg/day (a maximum dose of 30mg at baseline) and Methotrexate 15 mg weekly for 12 weeks. Prednisolone and Methotrexate (Control Arm) Methotrexate prednisolone 0.75mg/kg/day (a maximum dose of 30mg at baseline) and Methotrexate 15 mg weekly for 12 weeks. Prednisolone and Apremilast (Test Arm) Prednisolone prednisolone 0.75mg/kg/day (a maximum dose of 30mg at baseline) and Apremilast 30 mg twice daily for 12 weeks.
- Primary Outcome Measures
Name Time Method Pain by Visual Analogue Scale (VAS) score 8 weeks and 12 weeks Change in Visual Analogue Scale (VAS) score after treatment with prednisolone and methotraxate Vs Prednisolone and Apremilast at baseline, 8 weeks and 12 weeks. The VAS consists of a 10 cm line, with two endpoints representing 0 ('no pain') and 10 ('pain as bad as it could possibly be') interpretation of the scores: 0 =No Pain 2 = Mild 4 = Nagging 6 =Miserable 8 =Intense 10 = Worst
- Secondary Outcome Measures
Name Time Method Severity by Physician global assessment of disease (PGA) score 8 weeks and 12 weeks compare the proportion of patients achieving a reduction of Physician global assessment of disease (PGA) score of 0 or a 2-grade reduction (minimum initial PGA 3) after treatment with prednisolone and methotraxate Vs Prednisolone and Apremilast at baseline, 8 weeks and 12 weeks by using a 6-point disease severity scoring system.
(0=clear, 1=almost clear, 2=mild, 3=moderate, 4=severe, 5=very severe).Severity and pain by oral mucosal disease severity score 8 weeks and 12 weeks the change in oral mucosal disease severity score (maximum 106) after treatment with prednisolone and methotraxate Vs Prednisolone and Apremilast at baseline, 8 weeks and 12 weeks.
Total score = Site score + Activity score + pain Score (Maximum 106) higher scores indicating greater disease activityserum IL 6 level 12 weeks Change in serum IL 6 after treatment with prednisolone and methotraxate Vs Prednisolone and Apremilast he levels of salivary and serum IL-6 were significantly higher among patients with OLP than among healthy control participants
Quality of life by using oral health-related quality of life score (ORAL HEALTH IMPACT PROFILE - 14 ) 8 weeks and 12 weeks Change in the oral health-related quality of life from baseline after 8 and 12 weeks.
designed to assess patients' perception of the impact of oral disorders on their quality of life (QoL).
The OHIP-14 scores can range from 0 to 56 and are calculated by summing the ordinal values for the 14 items. The domain scores can range from 0 to 8. Higher OHIP-14 scores indicate worse and lower scores indicate better OHRQolIncidence of treatment-emergent adverse events of both test and control group 12 weeks treatment-emergent adverse events in both the groups The adverse events in the patients are to be assessed by non-directive questioning at the time of the follow-up visit. Patients can access the investigators directly in case of any adverse events and report them. All adverse events irrespective of their previous reported status are to be recorded with details about nature, intensity, duration, measures taken, outcome, and causal relationship to prednisolone, methotrexate and apremilast.
