Efficacy and Safety of Methotrexate Versus Placebo in Adults With Atopic Dermatitis.
- Conditions
- Moderate to Severe Atopic Dermatitis
- Interventions
- Drug: Placebo
- Registration Number
- NCT06239311
- Lead Sponsor
- medac GmbH
- Brief Summary
Atopic dermatitis is an ongoing condition that causes skin irritation, redness, and itchiness. Treatments are usually topical - applied to the skin (e.g., moisturisers or medicated creams) - but a wider variety of systemic treatments (that target the whole body) are needed for those whose condition does not improve with topical treatments. Methotrexate, a drug approved for similar conditions such as arthritis and psoriasis, has been shown to improve atopic dermatitis. This randomised, controlled clinical trial will investigate how effective.
