排除标准

结局指标

主要结局

Change From Baseline in the Mean Asthma Control Questionnaire (ACQ) Score at Day 92

时间窗: Day 1 and 92

Asthma Control Questionnaire (ACQ) is a participant-reported questionnaire to assess the asthma control with 6 items assessing night-time waking, symptoms on waking, activity limitation, shortness of breath, wheeze, and rescue short-acting beta agonist use. Each item was rated on a 7-point Likert scale ranging from 0 (no impairment) to 6 (maximum impairment). Overall ACQ score is the mean of the 6 item scores with a score range of 0 (well controlled) to 6 (extremely poor controlled). Data collected on Day 1 prior to dosing was considered as baseline. Results were reported for overall ACQ score.

次要结局

  • Time to First Observed Asthma Control(Day 1 to Day 92 and Day 169)
  • Number of Puffs of Rescue Beta-2 Agonist Per Week(Day -7 to 169)
  • Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) Recorded at Study Sites at Day 1, 15, 29, 43, 57, 71, 85, 92, 127 and 169(Day 1, 15, 29, 43, 57, 71, 85, 92, 127 and 169)
  • Change From Baseline in Peak Expiratory Flow (PEF) Recorded at Home Every Week From Day 1 to 169(Day -7 to 1 (predose), Day 2 to 169)
  • Asthma Quality of Life Questionnaire (Standardized Version) (AQLQ[S]) Scores(Day 1, 29, 57, 92, 127 and 169)
  • Change From Baseline in Asthma Quality of Life Questionnaire (Standardized Version) (AQLQ[S]) Scores at Day 29, 57, 92, 127 and 169(Day 1, 29, 57, 92, 127 and 169)
  • Patient Global Impression of Change (PGIC)(Day 92 and 169)
  • Percentage of Participants With Mean Asthma Control Questionnaire (ACQ) Score Less Than or Equal to 0.75 or ACQ Score Greater Than 0.75 But Less Than 1.5(Day 92 and 169)
  • Percentage of Participants With Positive Serum Antibodies to CAT-354 at Any Visit(Day 1, 92 and 169)
  • Serum Concentration for CAT-354(Predose on Day 15, 29, 43, 57, 71 and 85; Day 88, 92, 99, 127, and 169)
