NCT ID: NCT03406078

Last Updated: 2021-12-09

Results Overview

Categorized percent reduction from baseline at Week 48. Percent change from baseline is defined as {final dose-baseline dose)/baseline dose}\*100, and the categories of percent change from baseline in daily OCS dose are defined as: ≥90% to ≤100% reduction, ≥75% to \<90% reduction, ≥50% to \<75% reduction, \>0% to \<50% reduction, and, no change or any increase.

Participant Flow

The study was conducted at 60 centres in 7 countries. A total of 243 subjects were screened between 5MAR2018 and 27SEP2019, of which 150 were randomized and treated. 93 subjects were screen failures mainly due to exclusion criteria met and/or inclusion criteria not met. Assignment was done by Interactive Voice/Web Response System(IVRS/IWRS).

The screening period included a Run-in (2 weeks) and an OCS optimization phase (up to 8 weeks). At the end of period, subjects were randomized in 1:1 ratio for tezepelumab or placebo. Randomization was stratified by region (Central/Eastern Europe, Western Europe and North America, Rest of the World).

Change from baseline in Asthma Symptom Diary score at Week 48. The Asthma Symptom Diary comprises of 10 items (5 items in the morning; 5 items in the evening). Asthma symptoms during night time and daytime are recorded by the patient each morning and evening in the daily diary. A daily ASD score is the mean of the 10 items. Responses for all 10 items are required to calculate the daily ASD score; otherwise, it is treated as missing. For the 7-day average asthma symptom score, scoring is done with no imputation using the mean of at least 4 of the 7 daily ASD scores as a mean weekly item score. The 7-day average ASD score ranges from 0 to 4, where 0 indicates no asthma symptoms.

Change from baseline in AQLQ(S)+12 as compared to placebo at Week 48. The AQLQ(S)+12 is a questionnaire that measures the health-related quality of life experienced by asthma subjects. The total score is defined as the average of all 32 questions in the AQLQ(S)+12 questionnaire. AQLQ(S)+12 is a 7-point scale questionnaire, ranging from 7 (no impairment) to 1 (severe impairment).

Change from baseline in EQ-5D-5L at Week 48. The EQ-5D-5L questionnaire assesses 5 dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 response options (no/slight/moderate/severe/extreme problems) that reflect increasing levels of difficulty. The EQ-5D-5L scores are converted into a single index-based value (Health State Valuation), using the UK population-based weights. The Helth State Valuation is scored between 0 to 1, where higher score indicates a better health state.

Population: The work productivity loss is only applicable to subjects who were employed, which is a subset of the study population. The class productivity loss is only applicable to subjects attending school, which is a subset of the study population. No subject in Placebo arm has selected the option 'in school' on the WPAI+CIQ questionnaire at Week 48.

Change from baseline in WPAI+CIQ score at Week 48. The WPAI+CIQ consists of 10 questions about how asthma and asthma related issues impact a subject's ability to work, attend classes, and perform regular daily activities. Work (Class) productivity loss is derived by sum of percentage of missed work (class hours) due to asthma and product of percentage of actual working hours (class) times degree of asthma affecting work (class) productivity while working. Percentage of missed work (class hours) due to asthma is calculated by number of hours missed work (class) due to asthma divided by total number of hours missed work (class) plus number of hours actually worked (in class). Activity impairment is the degree health affected regular activities (other than work or class) rated from 0 to 10, with 0 meaning no effect, divided by 10, and then expressed as a percentage.

Transiently positive is defined as having at least one post baseline ADA positive assessment and not fulfilling the conditions of persistently positive. Treatment boosted ADA defined as baseline positive ADA that was boosted to a 4 fold or higher level following treatment.
