Simvastatin for the Prevention of
Exacerbations in Moderate-to-Severe COPD
(STATCOPE)
Presented by Ali Naqvi, MD
History
“Use of Statins and Lung Function in Current or Former Smokers” – Keddissi, et al. Retrospective Cohort study at Okalahoma City’s VA
Hospital in 2005 Conducted chart reviews of 418 patients: Statin vs. Non-
statin Smokers or Former-smokers Abnormal baseline PFT findings (2x’s 6 months apart), with
either obstructive (n= 319) or restrictive disease (n = 99) End points to evaluate decline in PFT’s & need for urgent
care Results: Statin group had lower decline in FEV1 and FVC
vs. non-statin group (p<0.001)& ↓urgent care visits in obstructive patients (p<.02)
Conclusion: Statins can be an effective tx for lung disease
Quick Recap
STATCOPE Trial Methods Multi-center randomized, parallel-group, placebo
controlled trial (March 2010- Oct 2013)
Primary Exposure: 40mg Simvastatin vs. Placebo
Primary Outcome: Exacerbation Rate (# of exacerbations per person-year)
Secondary Outcomes: Time to First Exacerbation Severity of Exacerbation (mild, moderate, severe, very
severe) Quality of Life (SGRQ & SF-36 questionnaires) Spirometric Values
Methods Cont’d
Inclusion Criteria Exclusion Criteria
40-80 years of age Active Liver Disease or alcoholism
Clinical Diagnosis of Moderate-to-Severe COPD based on GOLD criteria
History of statin use or require statin based on ATP III guidelines
FEV1/FVC < 70% post bronchodilator use
FEV1 < 80% post bronchodilator use
Receiving medications contraindicated with statins
10+ pack year smoking history
In the past year (need one of the following):-Use of oxygen-Use of steroids or antibiotic agents for respiratory issues-ED presentation or admission for COPD

Results- Acute Exacerbations per per-yr
Results- Effect of Statin on time to first exacerbation
Results
Interim Analysis/Monitoring Plan Data & Safety monitoring board conducted
interim analysis every 6 months during the study
After 3 years, when all primary and secondary outcome measures were the same between the two groups, the data and safety monitoring board voted to stop the STATCOPE trial due to futility.
Conclusions Simvastatin 40mg did not affect exacerbation
rates for patients with moderate-to-severe COPD
Simvastatin also had no effect on lung function or disease-specific quality of life
Simvastatin has no role in the prevention of exacerbations in patients with moderate-to-severe COPD
Author reported limitations Limitations
Terminated study after 3 years due to futility Lack of use of an inflammatory marker (CRP or
ESR) to screen patients for enrollment in the study Limited to those only with moderate-to-severe
COPD
Critical Appraisal (Strengths/Weaknesses) Strengths
Study design Excellent Follow-Up rates Sample size
Weaknesses No information provided regarding blinding of
investigators (may introduce bias) Self-reported exacerbation events and adherence
by subjects
