Criteria

Inclusion Criteria:

Males and females ≥ 18 years old of non-child bearing potential or of child bearing potential committing to consistent and correct use of an acceptable method of birth control
Subjects with a reliable clinical history of asthma documented at least 12 weeks prior to screening
Subjects with a pre-bronchodilator FEV1 of > 40% and <85% of the predicted value during the screening visit and on the first day of treatment
Subjects who are currently non-smoking and have not used tobacco products (i.e., cigarettes, cigars, pipe tobacco) within the past year, and had < 10 pack-years of historical use
Subjects with > 15% reversibility of FEV1 within 30 minutes following 360 mcg of albuterol inhalation (pMDI). Note: This test may be repeated on a different day if the patient fails the first attempt; and if the patient achieves at least 10% reversibility and the Investigator thinks that a second attempt is appropriate
Subjects who are able to discontinue their asthma medications (inhaled corticosteroids and long-acting beta agonists) during the run-in period and for the remainder of the study
Subjects who are able to replace current short-acting beta agonists (SABAs) with salbutamol/albuterol inhaler for use as needed for the duration of the study (subjects should be able to withhold all inhaled SABAs for at least 6 hours prior to lung function assessments on study visits)
Subjects who are able to continue the following medications without a significant adjustment of dosage, formulation, or dosing interval for the duration of the study, and judged able by the investigator to withhold them for the specified minimum time intervals prior to each clinic visit: short-acting forms of theophylline for 12 hours, twice-a-day controlled release forms of theophylline for 24 hours, once-a-day controlled-release forms of theophylline for 36 hours
Subjects who are able to discontinue the following medications for the specified minimum time intervals prior to the run-in period and for the remainder of the study: oral and parenteral corticosteroids for 1 month and oral short-acting beta agonists for 12 hours

Subjects who are able and willing to give their written informed consent to participate in the study.

**********************************************************

Exclusion Criteria:

Female Subjects who are pregnant or breastfeeding
Subjects who have life-threatening asthma in the last 10 years, as defined as a history of asthma episode(s) requiring intubation, and/or associated with hypercapnoea; respiratory arrest or hypoxic seizures, asthma-related syncopal episodes(s), or hospitalizations within the past year or during the run-in period
Subjects with evidence or history of clinically significant disease or abnormality including congestive heart failure, uncontrolled hypertension, uncontrolled coronary artery disease, myocardial infarction, or cardiac dysrhythmia. In addition, historical or current evidence of significant hematologic, hepatic, neurologic, psychiatric, renal, or other diseases that in the opinion of the investigator, would put the patient at risk through study participation, or would affect the study analyses if the disease exacerbated during the study
Subjects with a hypersensitivity to any sympathomimetic drug (e.g. Salmeterol or salbutamol/albuterol) or any inhaled, intranasal or systemic corticosteroid therapy
Subjects who are on other medications with the potential to affect the course of asthma or to interact with sympathomimetic amines (e.g. beta blockers, oral decongestants, benzodiazepines, digitalis, phenothiazines, polycyclic antidepressants, monoamine oxidase inhibitors)
Subjects with a viral or bacterial upper or lower respiratory tract infection or sinus or middle ear infection within 4 weeks prior to the screening visit or during the run-in period
Subjects with any factors (e.g. infirmity, disability, or geographic location) that the investigator feel would likely limit the patient's compliance with the study protocol or scheduled clinic visits
Subjects who have used any investigational drug in any clinical trial within 1 month of receiving the first dose of OT329 Solis™ study medication
Subjects who cannot communicate reliably or who are unlikely to co-operate with the requirements of the study, in the opinion of the Investigator
Subjects with a milk protein allergy
