Design outcomes

Primary

MeasureTime frame
Main Objective: To assess the effect of tezepelumab SC Q4W on asthma exacerbations in adult and adolescent subjects with severe uncontrolled asthma compared with placebo.;Secondary Objective: 1) To assess the effect of tezepelumab SC Q4W on: a) pulmonary function compared with placebo. b) health status/health related quality of life compared with placebo. c) asthma control compared with placebo. d) asthma symptoms compared with placebo. Other Secondary objectives: 1) To assess the effect of tezepelumab SC Q4W on: a) other endpoints associated with asthma exacerbations. b) biomarkers. c) other asthma control metrics. d) general health-related quality of life. e) patient (PGI-C and PGI-S) and clinician impression of overall asthma severity (CGI-C). 2) To evaluate the effect of tezepelumab SC Q4W compared with placebo on health resource utilization and productivity loss due to asthma. 3) To evaluate the pharmacokinetics (PK) and immunogenicity of tezepelumab.;Primary end point(s): Primary endpoint: Annualized asthma exacerbation rate (AAER).;Timepoint(s) of evaluation of this end point: Baseline to Week 52.

Secondary

MeasureTime frame
Secondary end point(s): Key Secondary endpoints: 1) Change from baseline in the pre-dose/pre-bronchodilator (pre-BD) forced expiratory volume in 1 second (FEV1). 2) Change from baseline in Standardized Asthma Quality of Life Questionnaire for 12 years and older (AQLQ(S)+12) total score. 3) Change from baseline in Asthma Control Questionnaire-6 (ACQ-6) score. 4) Change from baseline in weekly mean daily Asthma Symptom Diary score. Other Secondary endpoints: 1a) Time to first asthma exacerbation. b) Proportion of subjects with =1 asthma exacerbation. c)Annualized rate of exacerbations associated with emergency room visit, urgent care visit, or hospitalization. 2) Change from baseline in fractional exhaled in nitric oxide FENO (ppb), peripheral blood eosinophils and total serum IgE. 3) Change from baseline in weekly mean rescue medication use, weekly mean morning and evening peak expiratory flow (PEF), and weekly mean number of night time awakenings. 4) Asthma specific resource utilization (eg. unscheduled physician visits, unscheduled phone calls to physicians, use of other asthma medications). Work Productivity and Activity Impairment Questionnaire and Classroom Impairment Questionnaire (WPAI+CIQ) score. 5) PK: Serum trough concentrations; Immunogenicity: Incidence of anti-drug antibodies and neutralizing antibodies. 6) European Quality of Life - 5 Dimensions 5 Levels Questionnaire (EQ-5D-5L) score. 7) Patient Global Impression of Change/Severity (PGI-C, PGI-S) and Clinician Global Impression of Change (CGI-C).;Timepoint(s) of evaluation of this end point: Key Secondary endpoints: 1) Baseline, Week 52 2) Baseline, Week 52 3) Baseline, Week 52 4) Baseline, Week 52 Other Secondary endpoints: 1) Baseline to Week 52 2) Baseline, Week 52 3) Baseline, Week 52 4) Week 52 5) Baseline to Week 52 6) Week 52 7) Week 52
