A Phase II Study of Imiquimod 5 % Cream for the Treatment of Hemangioma in Infancy
Hemangiomas of infancy, the most common benign tumors of infancy, are congenital or early infancy lesions characterized by a rapid postnatal growth, with high expression of angiogenic stimulators for 9-18 months, followed by slow regression for 5-9 years. Current therapies for the hemangiomas are usually restricted to more severe forms due to the risks of adverse effects, inconvenience and cost. Nevertheless, a substantial amount of the psychological discomfort and morbidity can be caused by untreated hemangiomas, especially those in the face.
Recently, Imiquimod 5% cream has emerged as a safe an effective drug for several skin conditions that benefit from modulation of the activity of the immune system, such as common warts and various forms of the skin pre-cancerous and cancerous lesions. Small case reports series have suggest that it could also be useful in hemangiomas, possibly through the inhibition of the angiogenesis by local IFN production.This is a small, open label study of 16 patients to document the efficacy of the Imiquimod 5% cream in the treatment of hemangioma of infancy (primary outcome). IFN and plasma drug levels, as well as clinical examinations and blood studies, will be carried out to evaluate safety of the treatment (secondary outcome). bFGF and VEGF will be measured in blood and urine in order to study the diagnostic and predictive value of these pro-angiogenic factors in the response of hemangiomas to the treatment with Imiquimod (secondary outcome).
The study is a phase II clinical trial of a once a day application of Imiquimod 5% cream, 3 to 7 times per week for a maximum of four months. The study held at the Dermatology Clinic of Sainte-Justine Hospital, and was completed within a 20 months timeframe after IRB approval.
