Efficacy of Losartan in Preventing Progression of COPD
This study is currently recruiting participants.
Verified by National Heart, Lung, and Blood Institute (NHLBI), July 2008
Sponsors and Collaborators: National Heart, Lung, and Blood Institute (NHLBI)
Merck
Information provided by: National Heart, Lung, and Blood Institute (NHLBI)
ClinicalTrials.gov Identifier: NCT00720226
  Purpose

Evidence in animals shows that losartan can prevent or reverse inflammation and lung damage due to smoking. The goal of this study is to determine whether this drug which is also used to treat hypertension can stabilize or improve lung function in people who have from chronic obstructive pulmonary disease (COPD).

Further study details as provided by National Heart, Lung, and Blood Institute (NHLBI):

Primary Outcome Measures:
  • Extent of emphysema on CT scan [ Time Frame: Measured at Month 12 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Pulmonary function testing [ Time Frame: Measured at Month 12 ] [ Designated as safety issue: No ]

Estimated Enrollment: 120
Study Start Date: July 2008
Estimated Study Completion Date: August 2012
Estimated Primary Completion Date: August 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
1: Experimental
Losartan 100 mg daily
Drug: Losartan
Losartan 100 mg daily
2: Placebo Comparator
Placebo 1 pill daily
Drug: Placebo
Placebo pill daily

Detailed Description:

Participants will be given either losartan in a dose of 50-100 mg per day for a period of one year. During that time, they will have lung function tests, breathing tests, and computed tomograms of the chest. These tests will determine whether there is inflammation in the lung and whether there is progressive involvement of the lung with COPD.
