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.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
