  1. Criner et al. NEJM 2014: 370; 23 Simvastatin for the Prevention of Exacerbations in Moderate-to-Severe COPD (STATCOPE) Presented by Ali Naqvi, MD

  2. History

  3. “Use of Statins and Lung Function in Current or Former Smokers” – Keddissi, et al. • Retrospective Cohort study at Okalahoma City’s VAHospital 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

  4. Quick Recap

  5. 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

  6. Methods Cont’d

  7. Results

  8. Results

  9. Results- Primary & Secondary Outcomes

  10. Results- Acute Exacerbations per per-yr

  11. Results- Effect of Statin on time to first exacerbation

  12. Results

  13. 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.

  14. 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

  15. 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

  16. 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
