Mean Change From Baseline in Trough (Evening Pre-dose and Pre- Rescue Bronchodilator) FEV1 at Week 8
Query!
Assessment method [1]
0
0
Pulmonary function was measured by forced expiratory volume in one second (FEV1), defined as the maximal amount of air that can be forcibly exhaled from the lungs in one second. Pre-dose and pre-rescue bronchodilator (albuterol/salbutamol) trough FEV1 (the measurement of FEV1 performed at the end of the dosing interval) was measured electronically by spirometry in the evening at the Baseline (BL) through Week 8 clinic visits. The highest of 3 technically acceptable measurements was recorded. The Visit 3 FEV1 assessment was used as the Baseline value. Change from Baseline in trough FEV1 was calculated as the value at Week 8 minus the value at Baseline. The analysis was performed using an Analysis of Covariance (ANCOVA) model with covariates of Baseline trough FEV1, country, sex, age, and treatment group.

Mean Change From Baseline in Daily Trough (Pre-dose and Pre-rescue Bronchodilator) Evening Peak Expiratory Flow (PEF) Averaged Over the 8-week Treatment Period
Query!
Assessment method [1]
0
0
PEF is defined as the maximum airflow during a forced expiration beginning with the lungs fully inflated. Trough PEF is defined as the maximal rate (speed) that a person can exhale during a short maximal expiratory effort after a full inspiration. PEF was measured by the participants using a hand-held electronic peak flow meter each evening prior to the dose of study medication and any rescue albuterol/salbutamol inhalation aerosol use. The best of three attempts was recorded by the participants in a daily diary. The Baseline value was derived from the last 7 days of the daily diary prior to the randomization of the participant. Change from Baseline was calculated as the value of the averaged daily evening PEF over the 8-week treatment period minus the value at Baseline. The analysis was performed using an ANCOVA model with covariates of Baseline trough evening PEF, country, sex, age, and treatment group.

Asthma symptoms were recorded in a daily dairy by the participants every day in the morning and evening before taking any rescue or study medication and before PEF measurement. A 24-hour period in which a participant's responses to both the morning and evening assessments indicated no symptoms was considered as symptom-free. The Baseline value was derived from the last 7 days of the daily diary prior to the randomization of the participant. Change from Baseline was calculated as the averaged value during the 8-week Treatment Period minus the value at Baseline. The analysis was performed using an ANCOVA model with covariates of Baseline, country, sex, age, and treatment group.

An adverse event (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. A serious adverse event (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 should have been exercised in other situations. Refer to the general AE/SAE module for a list of AEs (occurring at a frequency threshold >=3%) and SAEs.

Urinalysis parameters included: Urine Occult Blood (UOB), Urine Glucose (UG), Urine Ketones (UK), Urine Protein (UP), and Urine Leukocyte Esterase test for detecting White Blood Cells (UWBC). The dipstick was a strip used to detect the presence or absence of these parameters in the urine sample. The dipstick test gives results in a semi-quantitative manner; results for urinalysis parameters can be read as 1+, 2+, 3+, Large, Moderate, Negative (Neg), Small, and Trace. For UG, the result can be read as Neg, Trace, Trace or 1/10 grams per deciliter (G/dL), 1+ or 1/4 G/dL, 2+ or 1/2 G/dL, 3+ or 1 G/dL, 4+ or 2 or more G/dL, indicating proportional concentrations in the urine sample. Data are reported as the number of participants who had 1+, 2+, 3+, Large, Moderate, Neg, Small, or Trace levels at Baseline (BL) and Week 8 (W8)/Early Withdrawal (EW). The Baseline value was the measurement taken at screening (Visit 1).

Urine samples were collected for the measurement of urine specific gravity by dipstick method at Baseline and at Week 8/Early Withdrawal. The Baseline value was the measurement taken at screening (Visit 1). Specific gravity is a measure of the amount of material dissolved in the urine. Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density (mass of the same unit volume) of a reference substance. Normal urine has a specific gravity between 1.010 and 1.020.

Urine samples were collected for the measurement of urine pH by dipstick method at Baseline and at Week 8/Early Withdrawal. The Baseline value was the measurement taken at screening (Visit 1). Urine pH is an acid-base measurement. pH is measured on a numeric scale ranging from 0 to 14; values on the scale refer to the degree of alkalinity or acidity. A pH of 7 is neutral. A pH less than 7 is acidic, and a pH greater than 7 is basic. Normal urine has a slightly acid pH (5.0 - 6.0).

if the disease/condition exacerbated during the study. The list of additional excluded
conditions/diseases includes, but is not limited to the following: congestive heart
failure, clinically significant coronary artery disease, stroke within 3 months of
Visit 1, poorly controlled peptic ulcer, immunologic compromise, tuberculosis (current

medication or procedures (e.g. completion of daily diary). Neurological or psychiatric
disease or history of drug or alcohol abuse which in the opinion of the investigator
could interfere with the subject's proper completion of the protocol requirements
excludes study participation.

Key exclusion criteria
Exclusion Criteria for Randomization At the end of the run-in period, a subject will not be
eligible to enter the treatment period of the study if they meet any of the following
criteria.
1. Clinical Laboratory Abnormalities: Clinically significant abnormal laboratory tests
during Visit 1 which are still abnormal upon repeat analysis and are not believed to
be due to disease(s) present. Each Investigator will use his/her own discretion in
determining the clinical significance of the abnormality. When in doubt,
GlaxoSmithKline, or designee, should be notified so that a joint decision can be made.
2. Changes in asthma medication (excluding albuterol/salbutamol inhalation aerosol
provided at Visit 1).
3. Occurrence of a culture-documented or suspected bacterial or viral infection of the
upper or lower respiratory tract, sinus or middle ear during the run-in period that
led to a change in asthma management, or in the opinion of the Investigator is
expected to affect the subject's asthma status or the subject's ability to participate
in the study.
4. Asthma exacerbation, defined as any worsening of asthma requiring any treatment other
than rescue albuterol/salbutamol or regular inhaled corticosteroid use. This includes
requiring the use of systemic corticosteroids and / or emergency room visit or
hospitalization or a change in subject's regular inhaled corticosteroid dose.
5. A subject will not be eligible for randomization if he/she has an abnormal visual
oropharyngeal exam at the randomization Visit 3 (visual clinical evidence of oral
candidiasis).
6. Non-compliance with completion of the Daily Diary, defined as: -Completion of AM and
PM symptom scores on less than 4 days out of the last 7 days immediately preceding
Visit 3.
