Therapeutic Utility of Xolair in Patients Undergoing Aspirin Desensitization
Condition: Aspirin Sensitivity
MeSH terms: Hypersensitivity
Intervention: Omalizumab; placebo
Intervention description: Subjects randomized to Omalizumab prior to aspirin desensitization; Subjects randomized to Placebo prior to aspirin desensitization
Intervention MeSH terms: Omalizumab
Phase: Phase 4
Study type: Interventional

Allocation: Randomized
Intervention model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Enrollment: 16.0
Sex: All
Minimum age: 18 Years
Healthy volunteers: No

Summary:

      This is a 24 week double-blind study in which subjects will be randomized 2:1 to receive
      Xolair (Omalizumab) or placebo. 14 subjects will receive Xolair and 7 will receive placebo.
      Xolair injections will occur every 2-4 weeks. Aspirin desensitization will occur several
      weeks later. One month after desensitization, the final visit will occur in the GCRC.

      We hypothesize that administration of Xolair, a monoclonal anti-IgE antibody, prior to the
      aspirin desensitization will reduce severity of aspirin-induced reaction.
