Study to Determine the Effect of an Anti-IgE Agent on Inflammatory Cells in the Skin of Atopic Dermatitis Patients

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00822783

Brief Summary:
Elevated levels of immunoglobuline E in blood are said to promote the occurence of atopic dermatitis; in fact, many patients with atopic dermatitis have high IgE levels. This study tried to explore whether the depletion of IgE from blood and skin might result in a change of immunological parameters and might alter the clinical course of the disease.

  • treatment with omalizumab within the last 12 months before study treatment
  • known hypersensitivity to any ingredients of omalizumab or omalizumab- related drugs
  • elevated serum IgE levels for reasons other than atopy
  • ongoing immunotherapy
  • use of long-acting antihistamine astemizol within 3 months prior to visit1
  • use of medium-acting antihistamines (e.g. loratadine, cetirizine) within 5 days prior to visit 1

  • use of zafirlukast or other leukotriene receptor inhibitors and zileuton or other 5-lipoxygenase enzyme inhibitors within 3 days prior to visit 1
  • use of phototherapy or systemic therapy that is known or suspected to have had an effect on AD within 1 month prior to first application of study medication
  • treatment with topical therapy (other than hydrocortisone 1%) that is known or suspected to have had an effect on AD within 14 days prior to first application of study medication
  • use of systemic steroids (oral, intravenous, including intraarticular and rectal) within one month prior to first application of study medication. (Patients on a stable maintenance dose of inhaled steroids were allowed to participate)
  • use of systemic antibiotics within 2 weeks prior to first application of study medication
  • use of tranquilizers, hypnotic agents or tricyclic antidepressants within 2 weeks prior to the start of the study
  • immunocompromised patients or patients having a history of malignant disease
  • concurrent skin diseases
  • active bacterial, viral or fungal infections that required treatment with a prohibited medication
  • a history of recurrent herpes simplex infection having active lesions at baseline
  • tinea corporis / tinea cruris
  • clinically significant laboratory abnormalities
  • a history of noncompliance to medical regimens and patients who were considered potentially unreliable
  • evidence of drug or alcohol abuse or other factors limiting ability to fully cooperate
  • any condition or prior/continuing treatment which, in the opinion of the investigator, should have rendered the patient ineligible for the study.
