Trial Outcomes & Findings for Safety and Efficacy of GW685698X an Inhaled Corticosteroid Once Daily and Twice Daily for the Treatment of Asthma (NCT NCT00766090)

NCT ID: NCT00766090

Last Updated: 2016-12-08

Results Overview

Pulmonary function was measured by FEV1, defined as the maximal amount of air that can be forcefully exhaled in one second. FEV1 was measured electronically by spirometry. Trough FEV1 was the evening pre-dose, pre-rescue bronchodilator FEV1 measurement taken on Day 28 of the relevant treatment period. The analysis was performed using mixed model analysis of covarience (ANCOVA) with fixed effects of treatment, period, sex, and age. Participants were fitted as a random effect, and the period Baseline measurement was included as part of a bivariate response.

Participant Flow

Eligible participants (par.) at screening entered a 14-day Run-in Period. Par. were then randomized to 1 of 12 sequences: 6 had placebo and two doses of fluticasone furoate (FF), and 6 had placebo and two doses of fluticasone proprionate (FP) (allocation ratio of 7:2 \[FF:FP\]). 320 par. were screened and 190 were randomized.

Population: ITT Population

An AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or is a congenital anomaly/birth defect. Medical or scientific judgment was exercised in deciding whether reporting was appropriate in other situations. Refer to the general AE/SAE module for a list of AEs (occuring at a frequency threshold \>=3%) and SAEs.

Timeframe: From the first dose of the study medication up to Week 16/Early Withdrawal

Population: ITT Population

Participants were withdrawn from the study due to worsening of asthma (lack of efficacy) if they experienced a clinical asthma exacerbation or if clinic FEV1 fell below the FEV1 stability limit, or if during the 7 days immediately preceeding a visit the participant experienced either four or more days in which the PEF had fallen below the PEF stability limit or three or more days in which \>=12 inhalations/day of albuterol/salbutamol were used. A clinical asthma exacerbation is defined as the worsening of asthma requiring emergency room visits, hospitalization, or treatment with an asthma medication (inhaled or systemic corticosteroids) other than study medication or rescue salbutamol/albuterol.
