Primary Outcome Measures :
  1. Number of participants out of the total experiencing asthma worsening as assessed by changes in peak expiratory flow, FEV1, rescue medication use, and ACQ-5 score, and the occurrence of severe asthma exacerbations. [ Time Frame: 24 weeks ]
    Asthma worsening is defined as at least one of the following: peak expiratory flow less than or equal to 75 percent of baseline; forced expiratory volume in 1 second (FEV1) less than 80 percent of baseline; increase in rescue medication use of greater than or equal to 6 puffs per day compared to baseline; increase in Asthma Control Questionnaire (ACQ-5) score of greater than or equal to 0.5 compared to baseline; or the occurrence of a severe asthma exacerbation.

Secondary Outcome Measures :
  1. ACQ-5 Score [ Time Frame: 24 weeks ]
    Change from baseline in ACQ-5 score

  2. Pre-bronchodilator FEV1 [ Time Frame: 24 weeks ]
    Change from baseline in pre-bronchodilator FEV1

  3. Asthma worsening [ Time Frame: 24 weeks ]
    Time to first asthma worsening

  4. Post-bronchodilator FEV1 [ Time Frame: 24 weeks ]
    Change from baseline in post-bronchodilator FEV1

  5. AM peak expiratory flow [ Time Frame: 24 weeks ]
    Change from baseline in AM peak expiratory flow

  6. Incidence of Treatment Emergent Adverse Events [ Time Frame: 28 weeks ]
    To evaluate the safety and tolerability of GB001 as compared to placebo looking at only those adverse events that start on or after the first dose of the study drug or placebo respectively
