Study to Assess the Efficacy and Safety of Omalizumab Treatment on ICS Reduction for Severe IgE-mediated Asthma (MEXIC)
Multicentric, Open-label, Randomized, Parallel--group Study to Evaluate the Efficacy and Safety of Omalizumab in a 12- Month Period, in Patients With Severe IgE-mediated Asthma Inadequately Controlled With High Doses of Corticosteroids.
調査の概要

詳細な説明
This was a multicentric, open label, randomized, parallel-group study with a 12-month treatment period. Participants were assigned to one of the 2 treatment groups, omalizumab plus budesonide/formoterol or budesonide/formoterol alone.
The study comprised 4 phases:
During the 4-week run-in phase adult participants received budesonide 800 mg and formoterol 24 mg. If a participant complied with all inclusion and exclusion criteria and had received the according-to-age run-in proposed doses during the last month, the participant continued to the stable-steroid phase.
During the 16-week stable-steroid phase, adult and pediatric eligible participants were randomized to one of the two treatment groups.
During the 8-week steroid-reduction phase, adult and pediatric participants reduced 25% of the budesonide baseline dose every 2 weeks, depending of the asthma control, until they reached a 100% reduction of the baseline dose. The clinical control of asthma was defined according to criteria (GINA 2012).

- Use of methotrexate, gold salts, troleandomycin, cyclosporine, immunosuppressants, gammaglobulin or any other type of monoclonal antibody used during the 6 months prior to the initial visit.
- Use of omalizumab during the 4 months prior to de screening visit.
- History of renal disease, cardiovascular disease, metabolic disease, hematologic disease, gastrointestinal disease, as well as immunodeficiency or cerebrovascular disease currently under treatment but not-controlled.

Asthma Control Questionnaire (ACQ) at Baseline
時間枠:Baseline
|
The Asthma Control Questionnaire (ACQ) has six questions to be answered by the participants, each with a 7 point scale (0-good control, 6-poor control), and one question where the actual pre-bronchodilator Forced expiratory volume in 1 second (FEV1) value expressed in % of predicted FEV1 was classified to scores from 0 (> 95% of predicted) to 6 (< 50% of predicted).
The overall score is the average of the 7 questions; a minimum overall score of 0 = good control of asthma whereas a maximum overall score of 6 = poor control of asthma.

Asthma Quality of Life Questionnaire (AQLQ) at Baseline
時間枠:Baseline
|
The quality of life will be measured by the standardized version of the Asthma Quality of Life Questionnaire (AQLQ[S]) score for adults and the pediatric version of the AQLQ(S) for pediatric participants (PAQLQ[S]) .
The AQLQ(S) and PAQLQ(S0 contain 4 domains (activity limitations, symptoms, emotional function, and environmental stimuli), with a total of 32 items; each item is measured in a 7-point Likert scale of 1 to 7 (1 = severe impairment, 7 = no impairment).
All items are weighted equally.
Mean score is calculated across all items within each domain and the overall score is the mean score of the 32 items.
