- All
- Target Recruitment
- 186
- Written informed consent/assent signed and dated by the patient and/or parent/caregiver/legal guardian (as appropriate) before conducting any study related procedure
- Male or premenarchal female 4-11 years of age, inclusive, as of the screening visit (SV)
- Has a documented physician diagnosis of asthma per the EPR-3 Guidelines of a minimum of 6 months duration that has been stable for at least 4 weeks prior to the SV
- Has the ability to perform spirometry reproducibly consistent with ATS guidelines and protocol-specific guidelines
- Has FEV1 50-95% predicted for age, height and gender at the SV following a minimum 6-hour period without β2-agonist use. (Note: Predicted values of 49.50-49.99% may be rounded up to 50% and values of 95.01-95.49% may be rounded down to 95%.)

- Is maintained on low-dose inhaled corticosteroids (ICS, less than or equal to 200 mcg of fluticasone propionate per day or equivalent), leukotriene modifiers (LTM), or inhaled cromones, and/or on short-acting β2-agonists (SABA); as needed SABA alone is acceptable. The ICS, LTM, and cromone doses must have been stable for at least 4 weeks prior to the SV and should be maintained for the duration of the study
- Can self-perform peak expiratory flow rate (PEF) measurements with a handheld peak flow meter
- Can tolerate the withdrawal of applicable medications for qualification at screening
- Otherwise in general good health, defined as free of any concomitant conditions or treatment that could interfere with study conduct, influence the interpretation of study observations/results, or put the patient at increased risk during the trial, and with a clinically acceptable 6-month medical history, physical examination, 12-lead electrocardiogram (ECG), and vital signs
- Parents consenting are capable of understanding the requirements, risks and benefits of study participation, and, as judged by the investigator, capable of giving informed consent and being compliant with all study requirements (eg, visits, record-keeping)

Exclusion Criteria
- Known hypersensitivity to albuterol or any of the excipients in the inhaler formulations (eg, lactose, ethanol)

- History of a respiratory infection or disorder (including, but not limited to bronchitis, pneumonia, acute or chronic sinusitis, otitis media, influenza) that has not resolved within 4 weeks preceding the SV
- Any asthma exacerbation requiring oral corticosteroids within 3 months of the SV. A patient must not have had any hospitalization for asthma within 6 months prior to the SV.
- Initiation of immunotherapy during the study period or dose escalation during the study period. Patients being treated with immunotherapy prior to the SV must be using a stable (maintenance) dose (90 days or more) to be considered for inclusion.
- History of life-threatening asthma that is defined for this protocol as an asthma episode that required intubation and/or was associated with hypercapnea, respiratory arrest, or hypoxic seizures
- Use of any prohibited concomitant medications within the washout prescribed per protocol prior to study visits
- Use of any medication for asthma or allergic rhinitis that is prohibited per the protocol as described in the protocol
- The dosage of any required LTM, ICS, or inhaled cromones, has not been stable for at least 4 weeks. Intranasal corticosteroid and/or cromones have not been stable for at least two weeks prior to the SV. Allowed corticosteroid, LTM, and cromone asthma and allergy medications should be continued at the same doses during the conduct of the study.
- Presence of any non-asthmatic acute or chronic condition, including but not limited to bronchitis, emphysema, active tuberculosis, bronchiectasis, cystic fibrosis, clinically significant cardiovascular disease (including but not limited to cardiac arrhythmias and uncontrolled hypertension), clinically significant hepatic, renal, or endocrine dysfunction, stroke, uncontrolled diabetes mellitus, hyperthyroidism, convulsive disorder, and malignancy other than basal cell carcinoma. Significant is defined as any condition that, in the opinion of the investigator, would put the safety of the patient at risk through participation, or which could affect the safety or efficacy analyses
- Any other medical or psychological condition that in the investigator's opinion should preclude study enrollment
- Previous participation (received MDPI study medication) in an Albuterol MDPI study
- Study participation by clinical investigator site employees and/or their immediate relatives
- Study participation by related or non-related individuals living in the same household, ie, only one subject per household may participate in the study at the same time.
- Require continuous treatment with β-blockers, MAO inhibitors, tricyclic antidepressants, anticholinergics, and/or systemic corticosteroids
- Treated with oral or injectable corticosteroids within the 6 weeks prior to SV
- Hospitalization for acute asthma exacerbation >2 times in 12 months prior to screening and/or received emergency room treatment other than nebulized albuterol or been hospitalized for asthma exacerbations within 6 months prior to SV

- Primary Outcome Measures
Name Time Method Baseline Adjusted Percent Predicted Forced Expiratory Volume In 1 Second (FEV1) Area Under The Concentration Time Curve Up From Time Zero up to 6 Hours (AUC0-6) Over 3 Weeks 30 ±5 and 5 ±2 minutes prior to dosing, and at 5 ±2, 15 ±5, 30 ±5, 45 ±5, 60 ±10, 120 ±10, 240 ±10, and 360 ±10 minutes after completion of dosing on Days 1 and 22 Following measurement of the baseline FEV1 and dose administration on Days 1 and 22, FEV1 values (highest of 3 acceptable maneuvers) will be obtained at 5 (±2), 15 (±5), 30 (±5), 45 (±5), 60 (±10), 120 (±10), 240 (±10), and 360 (±10) minutes after the completion of dosing. Predicted FEV1 values were computed and adjusted for age, height, and gender according to Eigen et al (Eigen et al 2001) for participants 4 to 5 years of age and to Quanjer et al (Quanjer et al 1995) for participants aged 6 to 11 years using ATS criteria (American Thoracic Society/European Respiratory Society Statement 2007).
- Secondary Outcome Measures
Name Time Method Baseline Adjusted Peak Expiratory Flow (PEF) Area Under The Concentration Time Curve Up From Time Zero up to 6 Hours (AUC0-6) Over 3 Weeks 30 ±5 and 5 ±2 minutes prior to dosing, and at 5 ±2, 15 ±5, 30 ±5, 45 ±5, 60 ±10, 120 ±10, 240 ±10, and 360 ±10 minutes after completion of dosing on Days 1 and 22 Serial PEF measurements were obtained via spirometry. PEF measures for purpose of serial PEF assessment (pre and postdose) were collected from the spirometer assessed PEF, utilizing the values from the efforts selected based on the highest of 3 acceptable FEV1 maneuvers.
Summary of Participants With Adverse Events 6 Months Adverse events (AEs) summarized in this table are those that began or worsened after treatment with study drug (treatment-emergent AEs). 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 as mild (no limitation of usual activities), moderate, or severe (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.
