Trial Outcomes & Findings for Study Evaluating the Safety and Effects of MN-221 in Subjects Experiencing an Acute Exacerbation of Asthma (NCT NCT00683449)

NCT ID: NCT00683449

Last Updated: 2011-10-07

Results Overview

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.

Participant Flow

Upon presentation to the Emergency Department (ED) at a hospital participating in the study with an acute exacerbation of asthma, the Principal Investigator (ED physician) discussed the study with the potential subject.

Some subjects were consented for the study, but upon screening, failed to meet the inclusion and exclusion criteria, had an FEV1 \> 50%, or refused to participate.

240 μg MN-221 i.v. (Intravenous) Infusion for 15 Minutes
Initial dose: 16 μg/min of MN-221 for 15 minutes (total 240 μg). After safety data review meeting, chose escalation doses: 1) 30 μg/min for 15 minutes (total 450 μg), and 2) 16 μg/min for 15 minutes plus 8 μg/min for 105 minutes (total dose of 1,080 μg).Until the subject's FEV1 reached ≥ 70% predicted, the subject continued to receive the following standard treatment and assessment during the study treatment period: * Assessment of subject's signs and symptoms * Completion of a dyspnea index scale * Supplemental oxygen to maintain oxygen saturation, as measured by pulse oximetry of ≥ 90% * Albuterol (2.5 mg) via nebulizer given hourly NOTE: Albuterol (2.5 mg) via nebulizer and/or Ipratropium (0.5 mg) via nebulizer may have been given up to every 20 minutes and every hour, respectively, if deemed to be indicated by the Investigator. * Spirometry completed within 10 minutes of nebulizer treatments, followed by * Reassessment of signs and symptoms.

NOTE: Albuterol (2.5 mg) via nebulizer may have been given up to every 20 minutes if deemed to be indicated by the Investigator. * Ipratropium (0.5 mg) via nebulizer may have been given every hour if deemed to be indicated by the Investigator. * Spirometry completed within 10 minutes of nebulizer treatments, followed by * Reassessment of signs and symptoms. If the subject did not improve to FEV1 ≥70% of predicted during the study treatment period, the subject may have continued to receive further treatment, including hospital admission, at the discretion of the Investigator.
1,000-1,080 μg MN-221 i.v.
16 μg/minute for 15 minutes followed by 8 μg/minute for 105 minutes (total dose of 1,080 μg). Among the subjects in the 1,000 - 1,080 μg group, per protocol instructions, the two subjects originally randomized to receive 1,080 μg MN-221 were infused with study drug over a 120-minute period and the 1 subject originally randomized to receive 450 μg who actually received 1,000 μg was infused with study drug over a 15-minute period. Although there was this difference in infusion time, it was deemed appropriate to group these 3 subjects in the same dose group.

PRIMARY outcome

Timeframe: Baseline and Hour 2

Population: The analysis was performed on the Intention-to-Treat (ITT) population. Twenty-nine subjects met the study entry criteria, provided written informed consent, and were enrolled in the study.

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.

Timeframe: Baseline to Hour 2

Population: 29 subjects experiencing an acute exacerbation of asthma were at approximately 8 ED sites. The sample size was based on feasibility and precedent for this type of study, rather than statistical considerations.

FEV1 (L) was determined over time using a spirometer. Measure the mean change in FEV1 (L) from Baseline.

Timeframe: 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.

NOTE: Albuterol (2.5 mg) via nebulizer may have been given up to every 20 minutes if deemed to be indicated by the Investigator. * Ipratropium (0.5 mg) via nebulizer may have been given every hour if deemed to be indicated by the Investigator. * Spirometry completed within 10 minutes of nebulizer treatments, followed by * Reassessment of signs and symptoms. If the subject did not improve to FEV1 ≥70% of predicted during the study treatment period, the subject may have continued to receive further treatment, including hospital admission, at the discretion of the Investigator.
1,000-1,080 μg MN-221 i.v.
n=3 participants at risk
16 μg/minute for 15 minutes followed by 8 μg/minute for 105 minutes (total dose of 1,080 μg). Among the subjects in the 1,000 - 1,080 μg group, per protocol instructions, the two subjects originally randomized to receive 1,080 μg MN-221 were infused with study drug over a 120-minute period and the 1 subject originally randomized to receive 450 μg who actually received 1,000 μg was infused with study drug over a 15-minute period. Although there was this difference in infusion time, it was deemed appropriate to group these 3 subjects in the same dose group.
