i.v. infusion of MN-221 16 mcg/min for 15 minutes followed by 8 mcg/min for 105 minutes (total dose = 1,080 mcg)
Other Name: bedoradrine

i.v. infusion of placebo for 15 minutes
Other Name: bedoradrine

Primary Outcome Measures :
  1. Change of FEV1 (Forced Expiratory Volume in 1 Second) Expressed as Percent of Predicted After Two Doses of Albuterol (5 mg Each) and Ipratropium (0.5 mg Each) When Compared to FEV1 at Hour 2 After the Start of the Infusion of MN-221 or Placebo. [ Time Frame: Baseline and Hour 2 ]
    The primary efficacy summary was change from Baseline in FEV1 (percent predicted), at Hour 2. Baseline was defined as FEV1 (percent predicted) after two doses of albuterol (5 mg each) and ipratropium (0.5 mg each) and FEV1 (percent predicted) FEV1 at Hour 2 was defined as the FEV1 (percent predicted) at 2 hours after the start of the infusion of MN-221 or placebo. Change from Baseline in FEV1 (percent predicted), was summarized by treatment group at Hour 2.

Secondary Outcome Measures :
  1. FEV1 (L) The Forced Expiratory Volume in One Second as Measured in Liters Per Second. [ Time Frame: Baseline to Hour 2 ]
    FEV1 (L) was determined over time using a spirometer. Measure the mean change in FEV1 (L) from Baseline.

  2. Hospital Admission Rate During Visit 1 [ Time Frame: Hour -1.5 through Hour 5 ]
    After a patient in the emergency department (ED) presents with an acute exacerbation of asthma, the hospital proceeds with SOC procedures for this condition. Despite treatment in the ED, it is sometimes necessary to admit the patient into the hospital. In the study described here, the rate of hospital admissions was recorded.

Inclusion Criteria:

  1. Male or female;
  2. Have self-reported history of physician-diagnosed and treated asthma for ≥ 3 months;
  3. Have a diagnosis of an acute exacerbation of asthma upon presentation at the ED as defined by dyspnea and evidence of bronchospasm in an individual with a known history of asthma;
  4. Upon presentation to the ED the treatment provided included:

    • A brief history and physical examination that includes vital signs, auscultation, assessments of accessory respiratory muscle usage and the level of dyspnea the subject is experiencing;
    • Supplemental oxygen given to maintain oxygen saturation as measured by pulse oximetry of ≥ 90%;
    • Two doses of inhaled beta2-agonist (defined as albuterol 5 mg) via nebulizer (each dose given sequentially up to approximately every 20 minutes); simultaneously with
    • Two doses of an inhaled anti-cholinergic agent (defined as ipratropium 0.5 mg) via nebulizer (each dose given sequentially up to approximately every20 minutes);
    • One dose of corticosteroid of at least 60 mg given orally (prednisone) or intravenously (methylprednisolone); and
  5. Have a FEV1 ≤ 55% within 10 minutes of completing the treatment described in Inclusion Criterion #4;
  6. Have a negative urine pregnancy test if you are females of childbearing potential;
  7. Have ECG with no dysrhythmias (except sinus tachycardia);
  8. Have no clinical or electrocardiographic signs of ischemic heart disease as determined by the Investigator; and
