“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

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

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
