• Use of any protocol prohibited concomitant medications for asthma (any oral β2-adrenergic agonists) or any protocol prohibited concomitant non-asthma medications including treatment with β2-adrenergic receptor antagonists and non-selective β-receptor blocking agents such as β-blocking anti-hypertensive products (administered by any route), MAO inhibitors, and/or tricyclic antidepressants. (Subject's own MDI short-acting β-agonist rescue inhaler should be used until the start of the Run-In period when a study rescue inhaler is provided.)
• Inability or unwillingness to comply with the protocol requirements.
• History of life-threatening asthma [defined here as an asthma episode requiring intubation and/or associated with hypercapnea, respiratory arrest or hypoxic seizures.]
• Any asthma exacerbation within 3 months of the SV requiring oral or systemic corticosteroids or any hospitalization for asthma within 6 months of the SV.

Note: An exacerbation of asthma is defined as any worsening of asthma requiring any treatment other than rescue albuterol or the subject's regular asthma maintenance therapy. This includes requiring the use of systemic corticosteroids and/or emergency room visit or hospitalization or a change in subject's regular asthma maintenance treatment. A subject does not need to be withdrawn from the study due to an asthma exacerbation unless hospitalization is required or unless the principal investigator believes it is in the subjects' best interest to withdraw from the study.

• Previous participation in an inhaled Albuterol Spiromax® (Teva) study, with the exception of the ABS-AS-306 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, i.e. only one subject per household may participate in the study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Participants With Adverse Experiences During Weeks 0-12 (Double-Blind Period)	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 on a scale of mild, moderate and severe, with severe= an AE which prevents normal daily 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.	Day 1 to Week 12
Participants With Adverse Experiences During Weeks 13-52 (Open-Label Period)	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 on a scale of mild, moderate and severe, with severe= an AE which prevents normal daily 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.	Weeks 13-52
Electrocardiogram (ECG) Results At Weeks 0, 12, and 52	A standard 12-lead ECG was performed at screening, week 12, and week 52 or early termination/discontinuation. The ECG recording methods were centralized and standardized across all study participants. A centralized cardiologist was responsible for providing all ECG interpretations.	Weeks 0 (screening visit), 12, and 52
Change From Baseline in Blood Pressure Measurements to Week 12 and Week 52	Participants were seated at least 2 minutes before blood pressure measurements were obtained by either an electronic or manual sphygmomanometer. Week 12 values represent change from Week 0. Week 52 values represent change from Week 12.	Week 0, Week 12 and Week 52
Change From Baseline in Pulse Measurements to Week 12 and Week 52	Participants were seated at least 2 minutes before pulse measurements were obtained by radial pulse. Week 12 values represent change from Week 0. Week 52 values represent change from Week 12.	Week 0, Week 12 and Week 52
Participants With Abnormal and Clinically Relevant Physical Exam Findings at Weeks 0, 12 and 52	The physical exam was performed by a qualified healthcare professional, and when possible, the same qualified healthcare professional that performed the physical examination at study screening performed all the scheduled physical examinations. Abnormalities and clinical relevance were determined by the qualified healthcare professional. HEENT = head, eyes, ears, nose, throat	Weeks 0, 12 and 52

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Composite Measurement of Device Ruggedness From Baseline to Week 52	Device Ruggedness: Reports of any problems/malfunction of the device (e.g., lack of efficacy, problems/malfunction after the device is dropped or sustains physical impact).	Baseline to Week 52
Device Invitro Evaluations to Week 52	Device In Vitro Evaluations - All used study inhalers will be collected and a random selection of inhalers will be tested as follows: Fifty (50) Albuterol Spiromax® inhalers used during weeks 0-12 will be randomly selected for in vitro testing; Fifty (50) Albuterol Spiromax® inhalers used during weeks 12-52 will be randomly selected for in vitro performance testing	Baseline to Week 52
Daily AM Peak Expiratory Flow (PEF) to Week 52	Daily AM PEF will be recorded throughout the duration of the study to provide information on the subject's asthma status in order to assist in distinguishing between the use of back-up rescue medication related to an increased need for asthma symptom relief from that related to an issue with the Albuterol Spiromax® rescue inhaler.	Baseline to Week 52
