  Purpose
The purpose of this study is to determine the best dose of nebulized arformoterol, a quick onset but long acting beta agonist, for use in treating acute bronchospasm in asthmatics presenting to the the Emergency Department. Also this study will evaluate the side effect and safety profile of arformoterol when used in this situation.

Condition Intervention Phase
Acute Asthma Drug: arformoterol (RR formoterol) Drug: placebo Drug: levalbuterol Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Pilot Study to Determine the Most Effective Dose of Arformoterol for Treating Acute Asthmatic Patients Presenting to the Emergency Department and to Evaluate Its Side Effect and Safety Profile When Used in This Clinical Situation.

Primary Outcome Measures:
  • The Averaged Mean Percent Change From Baseline FEV1 and PEFR (Percent Predicted and Absolute) After the 3 Doses of Study Drug [ Time Frame: 1 hour ]

Secondary Outcome Measures:
  • Most Effective Dose of Inhalation Arformoterol for Treating Acute Bronchospasm in Asthmatics by Evaluating the Averaged Mean Percent Change From Baseline % Predicted FEV1 After 3 Doses of Study Medication in Each of the 3 Groups [ Time Frame: 1 hour ]
  • Number of Participants Treated With Arformoteral in Acute Asthma Exacerbation as a Measure of Safety and Tolerability. [ Time Frame: 5 hours ]
  • The Mean Percent Change From Baseline in the FEV1 and PEFR (Absolute and Percent Predicted) Following Each Dose of Study Drug [ Time Frame: 1 hour ]
  • The Mean Change From Baseline in the FEV1 and PEFR (Absolute and Percent Predicted) Following Each Dose of Study Drug [ Time Frame: 1 hour ]
  • The Peak Change (Liters) and Peak Percent Change From Baseline in the FEV1 and PEFR (Absolute and Percent Predicted) Following Each Dose of Study Drug [ Time Frame: 1 hour ]
  • The Time to Onset of a 15% Improvement in FEV1 for Each Dose (Individual and Cumulative) and Total Dose of Study Medication to Reach This [ Time Frame: 5 hour ]
  • The Time Required to Achieve a FEV1 and PEFR > 60% Predicted for Each Dose (Individual and Cumulative) [ Time Frame: 5 hours ]
  • Percent of Responders (Defined as Those Discharged Following Treatment Who Did Not Require Additional Therapy in the ED) [ Time Frame: 5 hours ]
    The 2 subjects enrolled were both discharged home after study protocol completion, with no further treatment required in the ED setting.

  • Percent of Patients in Each Group Requiring Additional Therapies After the First Hour of Study Drug Treatments [ Time Frame: 5 hours ]
    2 subjects were enrolled. Neither required additional asthma treatment after the 1st hour of study drug teatments.

  • All of the Primary and Secondary Endpoints Partitioned by the Presenting PFT in Quartiles and the Presenting S Albuterol Levels in Quartiles [ Time Frame: 5 hours ]
  • Pharmacokinetics of Arformoterol in This Clinical Setting [ Time Frame: 5 hours ]

Detailed Description:
Acute bronchospasm associated with exacerbations of asthma is a common problem. Currently the mainstay of treatment is inhalation albuterol, either levalbuterol or racemic mixture, in repetitive fashion depending on the resolution of the airways obstruction. Formoterol is a long-acting (>12 hours) selective beta2-agonist that has a very rapid onset of bronchodilatation (<3 minutes and thus similar to that produced by albuterol). Patients with acute bronchospasm could benefit from the prn use of formoterol as they would receive acute relief of their symptoms and this would last for a prolonged time period. Additionally formoterol has been reported to be 28-109 times as potent as albuterol and safe at doses of 54ug in healthy subjects and asthmatics. Racemic formoterol structurally has 2 chiral centers and thus is composed of 4 enantiomers. The RR form (or arformoterol) is the active bronchodilator and it is not clear what the physiologic actions of the other 3 enantiomers are. This study is the first to evaluate nebulized arformoterol solution for therapy of acute asthmatics presenting to the Emergency Department.
