Phase II Study – MN-221-CL-005

We completed a randomized, open-label, placebo-controlled Phase II clinical trial involving 17 patients in two dose cohorts at four clinical sites in the United States in September 2008. In one dosing cohort, each patient received MN-221 at a dose of 1,125 micrograms or placebo over one hour by a continuous intravenous infusion. In the other dosing cohort, each patient received MN-221 at a dose of 1,080 micrograms or placebo over two hours by a continuous intravenous infusion. Both infusion rates of MN-221 produced a marked and clinically significant improvement in FEV1. FEV1 results were expressed as “percent predicted” based on standard reference equations accounting for an individual’s race, gender, age and height. At the end of the one-hour infusion, FEV1 increased by 17.5 percent predicted for MN-221 compared to an increase of 3 percent predicted for placebo. At the end of the two-hour infusion, FEV1 increased by an average of 12.1 percent predicted for MN-221 compared to an increase of 1.4 percent predicted for placebo. Per the study protocol, no inferential statistical testing was performed. MN-221 was well tolerated by the patients who received either infusion rate of MN-221. There were no clinically significant safety concerns noted among adverse events, electrocardiogram (ECG) data, vital sign data or laboratory assessments collected throughout the study.
