Brief summary
Morphea is very hard to treat. In a small number of adult patients, Imiquimod has proven to be beneficial in decreasing the thickness of the morphea plaques , while improving their appearance. There are no studies to date proving its safety and efficacy in children with this disease. We propose to conduct a pilot study to assess to potential efficacy and relative safety of Imiquimod in children with plaque morphea.
Detailed description
Design: Prospective, open label, pilot study Settings: The Hospital for Sick Children, Specialized Morphea Clinic Study population: * Children 6-18 years of age * Plaque morphea measuring less than 10 cm2 in diameter ( for children with multiple lesions, only one will be treated) Intervention: Topical imiquimod applied 3-5 times a week for 6 months Outcome measures: Decrease in the thickness of the skin by clinical scores and ultrasonography Duration of the study: 12 months ( 2 baseline visits, 1 intervention visit, 5 follow-up visits)
Interventions
Treatment will last for 36 weeks. Patients will be instructed to apply Imiquimod three times per week for 4 weeks. If no local side effects are noted at the 4 week- follow-up visit, the frequency of the application will be increased to 5 weekly applications.

Eligibility
Inclusion criteria
* Age at diagnosis 6 to 18 years of age * Morphea plaques * Female subjects of childbearing potential must have a negative urine pregnancy test * Signed consent/assent form
Exclusion criteria
* Children who received topical corticosteroids, tacrolimus, vitamin D derivatives (calcipotriol, calcipotriol-betamethasone dipropionate) to the affected area in the previous four weeks * Children who were previously treated with Imiquimod on the affected areas * Children with no demonstrable ultrasonographic changes at the baseline evaluation * Children with evidence of skin breakdown on the proposed area to be treated at the time of enrollment due to potential increased absorption of the medication through impaired skin barrier * Female subjects of childbearing potential who do not agree to practice effective birth control methods for the duration of the study * Children who are/were (in the past 6 months) treated with systemic medications such as methotrexate and/or systemic corticosteroids * Co-morbidities: systemic sclerosis, juvenile rheumatoid arthritis, other systemic diseases
