Trial Outcomes & Findings for Asthma Clinical Research Network (ACRN) Trial - Macrolides in Asthma (MIA) (NCT NCT00318708)

NCT ID: NCT00318708

Last Updated: 2018-03-23

Results Overview

The Juniper asthma control questionnaire (ACQ) consists of six questions answered by the asthma patient with respect to symptoms, rescue medication use, and night-time awakenings due to asthma. A seventh item in the ACQ is the percent predicted FEV1. Each of the seven items is scored from from 0 (best) to 6 (worst), and then the seven items are averaged to yield a number from 0 (best) to 6 (worst). Asthma patients needed to display an ACQ greater than or equal to 1.25 in order to be eligible for randomization. A reduction of 0.5 units or more in the ACQ over the 16 weeks of treatment is considered to be clinically significant.

PRIMARY outcome

Timeframe: Measured every four weeks during the 16-week treatment period, with the change (week 16 minus baseline) as the primary outcome

Population: The number of participants for the analysis was determined as the number who completed the full 16 weeks (value at 16 weeks minus value at baseline).

The Juniper asthma control questionnaire (ACQ) consists of six questions answered by the asthma patient with respect to symptoms, rescue medication use, and night-time awakenings due to asthma. A seventh item in the ACQ is the percent predicted FEV1. Each of the seven items is scored from from 0 (best) to 6 (worst), and then the seven items are averaged to yield a number from 0 (best) to 6 (worst). Asthma patients needed to display an ACQ greater than or equal to 1.25 in order to be eligible for randomization. A reduction of 0.5 units or more in the ACQ over the 16 weeks of treatment is considered to be clinically significant.

The Asthma Quality of Life Questionnaire (AQLQ) consists of 32 questions, with each question ranging from 1 (worst) to 7 (best). The 32 questions are averaged to yield an overall score, which is reported here. Therefore, a positive change between the 16-week score and the baseline score represents improvement.
