About

Protocol Title: Open-label,single center study to evaluate the savety and efficacy of an intramuscular 12 week-course of Alefacept in patients with atopic dermatitis.

Study Phase: II

Study Design: Open-label, single center Primary Study Objective: to determine the safety and efficacy of one course of Alefasept when administered as a 15 mg intramuscular ( IM) injektion to patients with atopic dermatitis

Secondary Study Objective: to investigate key immunological parameters involved in the pathology of this common skin disease to interpret the clinical findings

Number of patients: 10

Study Population: Male and female patients, at least 18 years of age with atopic dermatitis, aktive inflammation, a severity score of 6-9 according to Langeland and Rajika and an EASI of >20

Treatment Groups: Alefacept will be administered as a 15 mg IM injection once a week for 12 weeks, followed by a 12-week follow-up period.

Full description

Atopic dermatitis is a common chronic eczematous skin disease,wich often begins early in infancy and runs a course of remissions and exacerbations. T-lymphocytes play a prominent role in this skin disease. they represent the majority of skin-infiltrating cells and patients suffering from AD also have increased levels of activated circulating T cells and increased levels of markers of lymphocyte activation such as L-selectin and IL-2R.

Inclusion criteria

must give written informed consent
must be at least 18 years of age
must have been diagnosed with atopic dermatitis fulfilling the diagnostic criteria of Hanfin und Rajka and having active inflammation

Patients older than 65 years
Systemic treatment for atopic dermatitis ( e.g. cyclosporine, mycophenolat- mofetil,inferferon-gamma, PUVA) or systemic treatment with immunosuppressive/immunomodulating substances( e.g. azathioprin,methotrexate,biologics or hyposensitization - therapy) for other indications within 28 days prior to baseline
