Aspirin: The prototypical analgesic used in the treatment of mild to moderate pain. It has anti-inflammatory and antipyretic properties and acts as an inhibitor of cyclooxygenase which results in the inhibition of the biosynthesis of prostaglandins. Aspirin also inhibits platelet aggregation and is used in the prevention of arterial and venous thrombosis. (From Martindale, The Extra Pharmacopoeia, 30th ed, p5)
acetylsalicylate : A benzoate that is the conjugate base of acetylsalicylic acid, arising from deprotonation of the carboxy group.
acetylsalicylic acid : A member of the class of benzoic acids that is salicylic acid in which the hydrogen that is attached to the phenolic hydroxy group has been replaced by an acetoxy group. A non-steroidal anti-inflammatory drug with cyclooxygenase inhibitor activity.

Trial Outcomes

Change From Baseline in Asthma Control Questionnaire (ACQ) Over 16 Weeks Using Mixed Model for Repeated Measures

"The ACQ is a 7-item instrument that measures asthma control (Juniper et al 1999). Six questions are self-assessments; the seventh item, completed by a member of the study staff, is the result of the patient's FEV1 measurement. Each item has 7 possible answers on a scale of 0 to 6, and the total score is the mean of all responses (the total scale is therefore 0-6). A higher score is an indication of poorer asthma control. The during treatment (Weeks 4, 8, 12 and 16) average ACQ was estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements.~Negative change from baseline scores indicate improvement in asthma control." (NCT01287039)
Timeframe: Day 1 (baseline, pre-dose), Weeks 4, 8, 12, 16

Change From Baseline in Asthma Quality of Life Questionnaire (AQLQ) to Week 16

"The AQLQ is a 32-item instrument administered as a self-assessment (Juniper et al 1992). The questionnaire is divided into 4 domains: activity limitation, symptoms, emotional function, and environmental stimuli. Patients were asked to recall their experiences during the last 2 weeks and to respond to each question on a 7-point scale (1=severe impairment, 7=no impairment). The overall AQLQ score is the mean of all 32 responses. Five of the activity questions were patient-specific, which means that each patient identified and scored 5 activities in which the patient was limited by asthma; these 5 activities were identified at the first visit and retained for all subsequent follow-up visits.~Positive change from baseline scores indicate improvement in quality of life." (NCT01287039)
Timeframe: Day 1 (baseline, pre-dose), Week 16

Change From Baseline in Asthma Symptom Utility Index (ASUI) Over 16 Weeks Using Mixed Model for Repeated Measures

"The ASUI is an 11-item instrument designed to assess the frequency and severity of asthma symptoms and side effects, weighted by patient preferences (Revicki et al 1998). ASUI is a utility score that ranges from 0 to 1, with higher values indicating better asthma control; info obtained from questionnaire about asthma symptoms.~The during treatment (Weeks 4, 8, 12 and 16) average ASUI was estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements.~Positive change from baseline values indicate improvement in asthma symptoms. Information was obtained from questionnaire about asthma symptoms." (NCT01287039)
Timeframe: Day 1 (baseline, pre-dose), Weeks 4, 8, 12, 16

Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) Over 16 Weeks Using Mixed Model for Repeated Measures

"FEV1 is a standard measurement of air movement in the lungs of patients with asthma obtained from pulmonary function tests. It is the volume of air expired in the first second of a forced expiration using a spirometer. Positive change from baseline scores indicate improvement in asthma control.~The during treatment (Weeks 4, 8, 12 and 16) average FEV1 was estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements."

Timeframe: Day 1 (baseline, pre-dose), Weeks 4, 8, 12 and 16

Change From Baseline in Short-Acting Beta-Agonist (SABA) Use Over 16 Weeks Using Mixed Model for Repeated Measures

"SABA are used for quick relief of asthma symptoms. To measure SABA use, at each clinical visit patients were asked to recall their usage of SABA therapy within the last 3 days of the scheduled visit. If usage was confirmed, the number of puffs used was recorded. For the purpose of summaries, an average daily usage was evaluated by dividing the total number of puffs recorded over 3 days by 3.~The during treatment (Weeks 4, 8, 12 and 16) SABA use was estimated using a mixed-effect model for repeated measures (MMRM) with fixed effects (treatment, stratification factors, sex, visit, interaction of treatment and visit), covariates (height, baseline value), and patient as the random effect for the repeated measurements.~Negative change from baseline scores indicate improvement in asthma control."

Participants With Treatment-Emergent Adverse Events

An adverse event was defined in the protocol as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator on a scale of mild, moderate and severe, with severe= an inability to carry out usual activities. Relation of AE to treatment was determined by the investigator. Serious AEs include death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical intervention to prevent the previously listed serious outcomes.
