Phase II Study – MN-221-CL-006
In May, 2009 we announced final results from its Phase II clinical trial (MN-221-CL-006) evaluating MN-221 at planned escalating doses of 240 to 1,080 micrograms in patients with severe, acute exacerbations of asthma treated in Emergency Departments. The study included 29 (13 treated with standard care only and 16 treated with MN-221 plus standard care) patients with severe, acute exacerbations of asthma. All patients received standardized care consisting of inhaled albuterol, ipratropium and oral steroid treatment. No safety concerns with adding MN-221 to standardized care were identified following review of electrocardiogram (ECG), laboratory and adverse experience data. The hospitalization rate among patients treated with standardized care only was 46 percent (six of 13), which was the anticipated rate, compared to a hospitalization rate of 25 percent (four of 16) among patients receiving MN-221 plus standardized care. This represents a 45 percent reduction in hospitalization rate among patients treated with MN-221. All hospitalizations were due to asthma exacerbations which were judged to be unrelated to study medication. As specified in the protocol for this clinical trial, no inferential statistics (i.e., p-values) were calculated for this study. Improvement in forced expiratory volume in 1 second (FEV(1)) values generally appeared to be greater for patients receiving MN-221 in addition to standardized treatment.
