Brief Summary:
The primary objective of the study is to evaluate the efficacy of TEV-53275 administered subcutaneously (sc) in adult participants with persistent asthma and an eosinophilic phenotype compared to placebo. A secondary objective is to evaluate the efficacy of TEV-53275 compared to placebo assessed by lung function, asthma symptoms, rescue medication use, and quality of life measures. Another secondary objective is to evaluate the safety and tolerability of TEV-53275 administered sc in adult participants with persistent asthma and an eosinophilic phenotype compared with placebo, and lastly, to evaluate the immunogenicity of TEV-53275 administered sc in adult participants with persistent asthma and an eosinophilic phenotype.

Condition or disease Intervention/treatment Phase

The planned study duration is approximately 16 months.

The total duration of study participation is approximately 34 weeks including up to a 2-week screening period, a 2-week run-in period, a 16-week treatment period, and a follow-up visit 14 weeks after the final treatment visit.

Primary Outcome Measures :
  1. Change from baseline in morning Forced Expiratory Volume in 1 Second (FEV1). [ Time Frame: Baseline, Week 12 ]
    FEV1 was the volume of air exhaled in the first second of a forced expiration as measured by spirometer. FEV1 was defined as the predose trough morning percent predicted FEV1 measurement at the randomization visit (Baseline [Day 1]) at the investigational center.

Secondary Outcome Measures :
  1. Percentage of asthma control weeks [ Time Frame: Week 1, Week 12, Week 16 ]
  2. Change from baseline in weekly average of daily morning trough (pre-rescue bronchodilator) FEV1 [ Time Frame: Baseline, Week 12, Week 16 ]
  3. Change from baseline in weekly average of rescue medication use [ Time Frame: Baseline, Week 12, Week 16 ]
  4. Change from baseline in percentage of asthma control days (no symptoms and no rescue medication use) [ Time Frame: Baseline, Week 12, Week 16 ]
  5. Time to first clinical asthma exacerbation (CAE) [ Time Frame: Week 30 ]
  6. Change from baseline in Asthma Control Questionnaire (ACQ-6) [ Time Frame: Baseline, Week 12, Week 16 ]
    Six questions are self-assessments (completed by the participant). Each item on the ACQ-6 has a possible score ranging from 0 to 6 (0=no impairment; 6=maximum impairment), and the total score is the mean of all responses.

  7. Change from baseline in Asthma Control Test (ACT) [ Time Frame: Baseline, Week 12, Week 16 ]
    A participant self-administered tool for identifying those with poorly controlled asthma comprising 5 items. Total scores range from 5 (poor control of asthma) to 25 (complete control of asthma), with higher scores reflecting greater asthma control.

  8. Change from baseline in Standardized Asthma Quality of Life Questionnaire (AQLQ[S]) [ Time Frame: Baseline, Week 12, Week 16 ]
    The questionnaire is a tool to measure the impact of asthma on a participant's quality of life (physical, emotional, social, and occupational). The questionnaire contains 32 items with a 2-week recall period and uses a 7-point Likert scale (7=not impaired at all to 1=severely impaired). Scores range from 1 to 7, with higher scores indicating better quality of life.

  9. Proportion of participants who achieve FEV1:FVC (forced vital capacity) ratio ≥0.80 [ Time Frame: Week 12, Week 16 ]
  10. Number of participants reporting at least one adverse event [ Time Frame: Week 30 ]
    Adverse events will include clinically significant laboratory test results (serum chemistry, hematology, and urinalysis), vital signs, 12-lead electrocardiogram (ECG) results, and injection site reactions.

  11. Number of participants who reported use of concomitant medications [ Time Frame: Week 30 ]
  12. Number of participants developing antidrug antibodies (ADAs) throughout the study [ Time Frame: Week 30 ]
