Brief Summary:

Protocol Title: Immunopharmacological effects of Rituximab in atopic dermatitis

Study Phase: Investigator driven study

Study Design: Open-label, single center.

Primary Study Objective: To determine the efficacy, safety and immunopharmacological effects of Rituximab (anti-CD20) administered as a 1000mg intravenous infusion on days 1 and 15 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: 6

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

Treatment Group: Rituximab will be administered as 1000 mg infusion intravenously at day 1 and 15, followed by a 24-week follow-up period.

Visit Schedule: Screening Visit (within 28 days prior to Visit 1) Treatment visits (Visits days 1, 3, 8, 15, 17) Follow-up Visits (Visits weeks 4, 8, 12, 16, 20, 24)

Visit 11/Early Termination Visit (if applicable) Visit 11 will serve as the Early Termination Visit for any patient who withdraws from the study between Visit 1 and 10.

Accepts Healthy Volunteers:   No

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 and Rajka and having active inflammation.
  • Must have a severity score of 6-9 according to Langeland and Rajka.

Exclusion Criteria:

  • Patients with other skin diseases that might interfere with the evaluation of AD.
  • Patients with severe diseases of other organ systems (e.g. cardiovascular, liver, kidney, psychiatric, neurologic) that might put the patient on risk during the study or might interfere with the evaluations (in the opinion of the investigator).
  • Patient older than 65 years.
  • Systemic treatment for atopic dermatitis (e. g. corticosteroids, cyclosporine, mycophenolat-mofetil, interferon-gamma, UVB, UVA, PUVA) or systemic treatment with immunosuppressive/immunomodulating substances (e.g. azathioprin, methotrexate, biologics or hyposensitization -therapy) within 28 days prior to baseline.
  • Local treatment for atopic dermatitis with pimecrolimus/tacrolimus, steroids > class III, instable use of steroids class <III, emollients or local antiseptics/antibiotics within 14 days prior to day 1.
  • Serious local infection (e.g., cellulitis, abscess) or systemic infection (e.g., pneumonia, septicemia) within 3 months prior to the first dose of Rituximab.
  • History of recurrent clinically significant infection.
  • Congenital or acquired immunodeficiency syndrome.
  • History of or a new diagnosis or treatment of an invasive malignancy within 5 years of enrollment. Patients with a history of treated squamous cell and/or basal cell carcinomas limited to the skin are not excluded.
  • For female patients, unless postmenopausal or surgically sterile, unwillingness to practice effective contraception, as defined by the investigator, during the study. The rhythm method is not to be used as the sole method of contraception. Female patients considering becoming pregnant while in the study are excluded.
  • Female patients who are currently pregnant or breast-feeding.
  • Current enrollment in any other investigational drug study.
  • Previous participation in this study or previous studies with Rituximab.
