Primary Outcome Measures:
  • Change in FcεRI/IgE positive skin cells [ Time Frame: Baseline through Day 85 post-treatment ] [ Designated as safety issue: No ]
    FcεRI/IgE positive skin cells will be measured from skin biopsies collected at baseline (pre-treatment) and then on Day 8 and at time points through Day 85.

Secondary Outcome Measures:
  • Change in FcεRI/ IgE on positive skin cells with respect to UAS7 score [ Time Frame: Baseline through Day 85 ] [ Designated as safety issue: No ]
  • Change in skin cell immune system markers [ Time Frame: Baseline through Day 140 post-treatment ] [ Designated as safety issue: No ]
  • Change in common blood cells [ Time Frame: Baseline through Day 140 post-treatment ] [ Designated as safety issue: No ]
  • Differences between affected and unaffected skin samples [ Time Frame: Baseline ] [ Designated as safety issue: No ]
  • Serum levels of omalizumab [ Time Frame: Baseline through Day 85 ] [ Designated as safety issue: No ]
  • Serum total and free IgE [ Time Frame: Baseline through Day 85 ] [ Designated as safety issue: No ]
  • Specific IgE [ Time Frame: Day 140 post-treatment ] [ Designated as safety issue: No ]
  • Urticaria activity score (UAS7) [ Time Frame: Day 140 post-treatment ] [ Designated as safety issue: No ]
  • Likert scale [ Time Frame: Day 140 post-treatment ] [ Designated as safety issue: No ]
  • Assessment of angioedema [ Time Frame: Day 140 post-treatment ] [ Designated as safety issue: No ]
  • Dermatology Life Quality Index (DLQI) [ Time Frame: Day 140 post-treatment ] [ Designated as safety issue: No ]
  • Skindex-29 [ Time Frame: Day 140 post-treatment ] [ Designated as safety issue: No ]
  • Chronic Urticaria Quality of Life Questionnaire (Cu-Q2OL) [ Time Frame: Day 140 post-treatment ] [ Designated as safety issue: No ]
  • Number of participants with adverse events, serious adverse events or death [ Time Frame: Day 140 post-treatment ] [ Designated as safety issue: Yes ]

Inclusion Criteria:

  • Diagnosis of chronic spontaneous urticaria refractory to H1 antihistamines at Baseline

Exclusion Criteria:

  • Clearly defined underlying etiology for chronic urticarias other than CIU (main manifestation being physical urticaria). This includes the following urticarias: Acute, solar, cholinergic, heat, cold, aquagenic, delayed pressure or contact, as well as the following diseases as these diseases may have symptoms of urticaria or angioedema: Urticarial vasculitis, urticaria pigmentosa, erythema multiforme, mastocytosis, hereditary or acquired angioedema, lymphoma, leukemia, or generalized cancer.
  • Previous treatment with omalizumab.
  • A history or presence of atopic dermatitis, bullous pemphigoid, dermatitis herpetiformis, senile pruritus or other skin disease associated with itch.

Other protocol-defined inclusion/exclusion criteria may apply.
