Further study details as provided by University of Colorado, Denver:

Primary Outcome Measures:
  • Change in the basophil proteome [ Time Frame: Baseline through week 13 ] [ Designated as safety issue: No ]
    In patients with chronic urticaria who respond clinically to omalizumab, the proteome of blood basophils will be measured at baseline (pre-treatment) and at weeks 6 and 13 (post-treatment).

Secondary Outcome Measures:
  • Change in basophil proteome in responders to omalizumab compared to non-responders to omalizumab [ Time Frame: Baseline through week 13 ] [ Designated as safety issue: No ]

Estimated Enrollment: 12
Study Start Date: April 2013
Estimated Study Completion Date: April 2017
Estimated Primary Completion Date: April 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Omalizumab
Patients will receive omalizumab 300mg subcutaneously every 4 weeks for 12 weeks at the study center.
Drug: Omalizumab

Other Name: Xolair

Detailed Description:
The purpose of this study is to evaluate for changes in the proteins produced in white blood cells (basophils) in patients with chronic hives who are treated with and respond to omalizumab.
