Trial Outcomes & Findings for A Non-inferiority Study to Evaluate Efficacy, Safety and Tolerability of NEUMOTEROL® 400 and SYMBICORT® Forte in Adults With Asthma (NCT NCT02233803)

NCT ID: NCT02233803

Last Updated: 2017-09-15

Results Overview

FEV1 is maximal amount of air, forcefully exhaled in one second. Trough FEV1 is defined as morning prebronchodilator and predose: 12 hours (h) after last evening dose D28 at end of each TP. Measured by spirometer in morning, before using bronchodilator and pre-dosing at wk1 D1 and wk4 D29 of each TP and test was performed within 30 minutes prior to dosing. Change from BL was analysed using mixed effects ANCOVA model fitting terms for subject-level (SL) BL, Adjusted period-specific (PS) BL, treatment group and period, with participant as random effect. PS BL value is pre-dose assessment collected on D1 of each TP. SL BL is arithmetic mean of PS BL values of participant. If only one of PS BL value is missing for participant, SL BL took value of other BL. If both PS BL values were missing, SL BL was set to missing. Period level BL=PS BL - associated SL BL.

Participant Flow

The study was conducted in adult asthma participants, at 11 centres in Argentina from 14 November 2014 to 11 December 2015.

Total 6 phases of study; pre-screening, screening/run-in, treatment period (TP) 1 washout, TP2, and follow-up. Out of total 239 enrolled participants, only 199 participants were randomized. 29 were screen failures and 10 were Run-in failures. One participant not randomized as the target number of participants for study was reached

NEUMOTEROL 400/ SYMBICORT FORTE
During TP1, participants received Regimen A where the eligible participants received, 1 inhalation of budesonide/formoterol fumarate (BFF), 400/12 microgram \[mcg\] (NEUMOTEROL 400) by single capsule inhaler each morning and evening for 4- weeks (Wks). This was followed by a wash out period of 4 Wks , during which all the participants received budesonide DPI 400 mcg (NEUMOTEX 400) twice daily.

The eligible participants were randomised to receive either Regimen A in TP1 and Regimen B in TP2, or Regimen B in TP1 and Regimen A in TP2 according to the randomisation schedule. Both the TPs were separated by a wash out period of 4 weeks. Regimen A: 1 inhalation of budesonide/formoterol fumarate (BFF), 400/12 microgram \[mcg\] (NEUMOTEROL 400) by single capsule inhaler each morning and evening. Regimen B: 1 inhalation of BFF 320/9 mcg (SYMBICORT FORTE) by turbuhaler inhaler each morning and evening.

PRIMARY outcome

Timeframe: BL (D1) and D29 (each TP)

Population: The intent to treat (ITT) population comprised of all randomized participants who received at least one dose of study treatment. This population was based on the treatment to which the participant was randomized. Only those participants with data available at the indicated time points were analyzed.

FEV1 is maximal amount of air, forcefully exhaled in one second. Trough FEV1 is defined as morning prebronchodilator and predose: 12 hours (h) after last evening dose D28 at end of each TP. Measured by spirometer in morning, before using bronchodilator and pre-dosing at wk1 D1 and wk4 D29 of each TP and test was performed within 30 minutes prior to dosing. Change from BL was analysed using mixed effects ANCOVA model fitting terms for subject-level (SL) BL, Adjusted period-specific (PS) BL, treatment group and period, with participant as random effect. PS BL value is pre-dose assessment collected on D1 of each TP. SL BL is arithmetic mean of PS BL values of participant. If only one of PS BL value is missing for participant, SL BL took value of other BL. If both PS BL values were missing, SL BL was set to missing. Period level BL=PS BL - associated SL BL.

SECONDARY outcome

Timeframe: (0-10 h) at D1 (each TP)

Population: ITT population. Only those participants with data available at the indicated time points were analyzed.

FEV1 is the maximal amount of air that can be forcefully exhaled in one second. FEV1 AUC (0 to 10h) was measured at beginning of each TP. AUC was derived using values observed at the following timepoints: 0 minute (pre-morning dosing), 5 minutes (m), 15m, 30m, 1, 2, 5, and 10h; post morning dosing FEV1 values on D1 of each TP. Pre-dose was taken as, 0h timepoint on the visit of interest, and all subsequent timepoints were calculated relative to that timepoint. FEV1 AUC was analysed using mixed effects ANCOVA model fitting terms for subject-level (SL) BL, Adjusted period-specific(PS) BL, treatment group and period, with participant as random effect.

SECONDARY outcome

Timeframe: BL up to W4 (each TP)

Population: ITT population. Only those participants with data available at the indicated time points were analyzed.

ACT was basically a five item questionnaire, to measure participant's asthma control. It comprised of five possible answers to each question, associated with a score of 1 to 5 (1=poor control and 5=good control), wherein the scores from each question were summed to give an overall score (5=poor control and 25=complete control). ACT was recommended during each visit and was completed by the participant before any procedures were performed, avoiding any influence of the participants response. Change from BL was analysed using mixed effects ANCOVA model fitting terms for subject-level (SL) BL, Adjusted period-specific(PS) BL, treatment group and period, with participant as random effect. PS BL value, is pre-dose assessment collected on D1 of each TP. SL BL, is arithmetic mean of PS BL values of participant. Participants with an ACT below 15 were excluded from the study.
