Brief Summary:
The objective of this clinical study is to examine the safety and effectiveness of intravenous MN-221 compared to placebo when administered as an adjunct to standard therapy in subjects experiencing an acute exacerbation of asthma.

Condition or disease Intervention/treatment Phase
Asthma Drug: MN-221 Drug: Placebo Phase 2

Detailed Description:

This is an international, randomized, double-blind, placebo-controlled, multi-center ED study. Each subject will receive MN-221 or placebo administered through a continuous intravenous infusion in addition to the standardized treatment for an acute exacerbation of asthma.

Upon presentation to the ED for assessment and treatment for an acute exacerbation of asthma the patient should receive standard of care consistent with the international guidelines (e.g., Global Initiative for Asthma [GINA] or the National Asthma Education and Prevention Program [NAEPP]) and required, in part, by this protocol prior to screening procedures being performed.

Prior to any study specific treatment or evaluation being performed a subject must have signed an IRB/EC/REB approved consent form. Once the subject has received the initial treatment regimen the subject will be assessed for response to the treatment including spirometry.If the subject meets all entry criteria the subject will be randomized to receive MN-221 or placebo. Throughout the screening process the subject will continue to receive standardized treatment consistent with the appropriate guidelines for the treatment of acute exacerbations of asthma.

Subjects enrolled in the study will receive an intravenous 1-hour infusion of MN-221 study drug or placebo. Subjects receiving MN-221 will be administered a total dose of 1200 μg.

During the study treatment period, the subject may continue to receive standardized treatment and be assessed. The study treatment period will be approximately 3 hours in length. Safety and efficacy will be monitored throughout the treatment period. PK parameters (if applicable) will be obtained from subjects at selected study sites. A blood sample for genomic evaluation will be collected during the treatment period (at participating sites) if the subject consents to the evaluation. An initial 24-hour post-randomization follow-up visit will be completed to evaluate the subject's health status as well as for safety and PK parameters (if applicable). A second follow-up contact will be completed by telephone seven days post-randomization for safety purposes and to evaluate the subject's health status.

A periodic risk/benefit evaluation will be performed by the study's Data Safety Monitoring Board.

    For the subjects using non-potassium-sparing diuretics (i.e. loop-diuretic or thiazide diuretic) without "potassium-sparing diuretics" (e.g., Triamterene or Spironolactone) OR without potassium supplementation of at least KCl 20 mEq/day whose potassium level <3.5 mEq/L (<3.5 mmol/L) at Screening.
