Study Endpoints
Primary Endpoints
To evaluate the annualized asthma exacerbation rate (AAER) in adult and adolescent subjects with severe uncontrolled asthma.
From Day 1 (randomization) to Week 52

The annual exacerbation rate is based on clinically significant (CS) exacerbations reported by the investigator in the electronic case (eCRF) over 52 weeks for subjects on GB-0895 as compared to placebo.

Number of participants with treatment related adverse events as assessed by CTCAE 5.0
Day 1 to Day 500
Secondary Endpoints
To evaluate the annualized asthma exacerbation rate (AAER) in adult and adolescent subjects with severe uncontrolled asthma and baseline eosinophils (EOS) < 300 cells/µL.
From Day 1 (randomization) to Week 52
Change from baseline in pre-bronchodilator (BD) forced expiratory volume in 1 second (FEV1)
From Day 1 (randomization) to Study Week 52
Change from baseline in Asthma Quality of Life Questionnaire AQLQ(S)12+ score
From Day 1 (randomization) to Week 52
