The purpose of this study is to investigate whether addition of Omalizumab enables a reduction in the dose of prednisone in patients with asthma and eosinophilic bronchitis.

This will be a double-blind placebo-controlled, 3-centre, randomized parallel group trial divided into two sequential study periods.

Period 1: After establishing the minimum dose of prednisone to maintain asthma control and maintain sputum eosinophils <3%, subjects will be randomized to either placebo or Omalizumab for 16 weeks (either once monthly for 4 months or every 2 weeks for 4 months).

Period 2: standardised prednisone reduction at intervals of 4-weeks until there is a clinical and eosinophilic exacerbation or bothersome steroid withdrawal effects. If patients have an exacerbation, they will be treated with prednisone. This patient will continue on Omalizumab or placebo during the entire duration of the study but not continue the phase of steroid reduction.

Primary Outcome Measures:
  • Proportion of patients with change in absolute % count of sputum eosinophil week 0 to week 12, and week 12 to week 32 [ Time Frame: From Week 0 to Week 12 and Week 12 to week 32 ]
  • Magnitude of the reduction in the dose of corticosteroid from week 12 to week 32. [ Time Frame: From Week 12 to Week 32 ]

Secondary Outcome Measures:
  • change in % sputum eosinophil [ Time Frame: From Week 0 to Week 32 ]
  • Blood eosinophils [ Time Frame: From Week 0 to week 32 ]
  • Forced Expired Volume in 1 second (FEV1) [ Time Frame: From Week 0 to Week 32 ]
  • Ratio of Forced Expired Volume in 1 second to Forced Vital Capacity (FEV1/VC) [ Time Frame: From Week 0 to Week 32 ]
  • Provocative concentration causing a 20% drop in FEV1 (PC20) [ Time Frame: From Week 0 to Week 32 ]
  • Asthma Control Questionnaire [ Time Frame: From Week 0 to Week 32 ]
  • Fraction of exhaled nitric oxide (FeNO) [ Time Frame: From Week 0 to Week 32 ]

Other Outcome Measures:
  • • Sputum eosinophilopoietic cytokines, chemokines, immunoglobulin levels, expression variation of constitutive immunoglobulin receptors. [ Time Frame: From Week 0 to Week 12 and Week 12 to week 32 ]
  • IgE antagonism and its effect on TSLP with respect to in situ eosinophilopoeisis and local eosinophil activity [ Time Frame: From Week 0 to Week 12 and Week 12 to week 32 ]
