Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a one-year study to look at the safety of a dry powder inhaler with albuterol. After a one-week run in, for the first 3 months subjects will use an inhaler with either albuterol or a dummy drug at regular times four times a day. Then for the last nine months of the study, all subjects will be given the albuterol dry powder inhaler and will use it only when needed to help with breathing problems. Subjects will need to keep a daily diary (both paper and electronic) throughout the study recording any inhaler use and health problems. There will be visits to the study doctor about once a month for a year. This study is intended to show that the albuterol dry powder inhaler works well and is safe for use over a long period of time.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Sponsor terminated this study due to the need for a modification to the Spiromax device utilized in this study; the problem identified has no impact on patient safety. Exposure ranged from 3 to 49 days with the majority of subjects receiving ≤30 days of double-blind treatment.

Study Groups

Albuterol Spiromax

Albuterol multi-dose dry powder inhaler (Spiromax) at a dose of 720 micrograms per day administered as 2 inhalations of 90 mcg /inhalation four times a day for the 12 week double-blind period. Participants then continue into the 40 week open-label period in which they take albuterol multi-dose dry powder inhaler (Spiromax) inhalations of 90 mcg /inhalation as required (PRN).

Group Type EXPERIMENTAL

Albuterol Spiromax

Intervention Type DRUG

Albuterol as a dry-powder inhaled orally using the Spiromax inhaler. Each inhalation delivers 90 micrograms (mcg). During the 12-week double-blind period, participants take two (2) inhalations four times a day (QID) at approximately 7:00 AM, 12:00 PM, 5:00 PM, and bedtime for a total dose of 720 micrograms per day for those paricipants randomized to the Albuterol treatment arm.

The double-blind period is followed by a 40-week open-label period in which all study participants will take Albuterol Spiromax 90 micrograms (mcg)/inhalation as needed (PRN).

Placebo Spiromax

Placebo delivered using a multi-dose dry powder inhaler (Spiromax) as 2 inhalations four times a day for the 12 week double-blind period. Participants then continue into the 40 week open-label period in which they administer albuterol multi-dose dry powder inhaler (Spiromax) inhalations of 90 mcg /inhalation as required (PRN).

Albuterol Spiromax

Intervention Type DRUG

Albuterol as a dry-powder inhaled orally using the Spiromax inhaler. Each inhalation delivers 90 micrograms (mcg). During the 12-week double-blind period, participants take two (2) inhalations four times a day (QID) at approximately 7:00 AM, 12:00 PM, 5:00 PM, and bedtime for a total dose of 720 micrograms per day for those paricipants randomized to the Albuterol treatment arm.

The double-blind period is followed by a 40-week open-label period in which all study participants will take Albuterol Spiromax 90 micrograms (mcg)/inhalation as needed (PRN).
