E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Chronic obstructive pulmonary disease patients who have skeletal muscle weakness. |
|
MedDRA Classification |
E.1.2 Medical condition or disease under investigation |
E.1.2 | Version | 9.1 |
E.1.2 | Level | LLT |
E.1.2 | Classification code | 10010952 |
E.1.2 | Term | COPD |
|
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To establish whether ACE inhibition can improve muscle strength in patients with COPD who have leg weakness. The effect of the study drug on the molecular pathways involved in muscle wasting will be determined in muscle biopsies taken before and after the study. |
|
E.2.2 | Secondary objectives of the trial | |
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Adult, consenting patient with COPD diagnosed according to GOLD criteria. Quadriceps weakness defined as a force in Kg<120% of body mass index. |
|
E.4 | Principal exclusion criteria |
Clinically unstable patients (within one month of exacerbation), those with a permanent pacemaker (which is a contraindication to magnetic stimulation), or significant co-morbidity, patients with an accepted indication for ACE inhibition (left ventricular dysfunction, diabetes) or a contraindication such as renovascular disease; creatinine clearance (estimated) <50); hypotension; use of anticoagulants (contra-indication to biopsy) or ACE-I or ATII receptor antagonists. Allergy to ACE-inhibitors. Pregancy
Patients will not be enrolled within three months of participation in a pulmonary rehabilitation program.

|
E.5 End points |
E.5.1 | Primary end point(s) |
Primary analysis will focus on the activity of the IGF-1 AKT pathways controlling muscle catabolism and anabolism assessed in muscle biopsies.
(A) Trial patients Measurements will include phosphorylated and non-phosphorylated AKT and mTOR as well as MyoD, MuRF and atrogin-1 mRNA and protein levels.
Changes in these pathways will be related to changes in muscle phenotype.
Secondary outcomes (1) Effect of ACE-I on quadriceps maximum voluntary contraction force (2) Effect of ACE-I on quadriceps endurance – T80 Time for force output in response to stimulation (3) Effect of ACE-I on quadriceps bulk (cross-sectional area) (4) Effect of ACE-I on systemic inflammation and serum IGF-1
