? OTC LOVASTATIN • Jesse M. Polansky M.D., M.P.H. jmpqz@yahoo.com • Representing self
? EFFICACY PRIMARY PREVENTION • FDA Statistical Review: • Uncertainty in post-hoc AFSCAPs analysis (low HDL population vs OTC population) • Absolute vs. Relative Risk Reduction • ? “Lower is Better” in moderate and low risk populations
? EMERGING SAFETY CONCERNS STATINS • Hemorrhagic Stroke - FDA label change atorvastatin based on post-hoc analysis SPARCL (4D/atorvastatin in diabetics on dialysis had a reported stroke finding also) • GI and Prostate Cancer Clinical Trial Findings (pravastatin and rosuvastatin respectively) • Cognitive, Behavioral (including suicide, sleep disturbances), and Gross Underreporting of Statin Side Effects (UCSD Statin Study) • ALS (WHO)
Balancing Risks & Benefits: NCEP ATP-III • 2003 NCEP Update : drug therapy only for Moderate Risk patients with LDL>160 Moderate Risk = 2 RF (includes Family Hx) and <10% Framingham Risk Score • The NCEP Moderate Risk category includes approx 13 million Americans who according to the guidelines only require Total Lifestyle Change (TLC) (?impact of self-rx)
NCEP Risk Categories Therapeutic Lifestyle Changes (TLC) Drug CHD and CHD Risk Equivalents 10-year risk >20% 24.1 20.7 2+ Risk Factors 10-year risk 10-20% 10.9 8.3 SUBTOTAL 35 29 2+ Risk Factors 10-year risk <10% 14.6 million 2.8 0-1 Risk Factor 15.6 million 4.7 SUBTOTAL 30.2 37.5 TOTAL 65.3M 36.5M
Balancing Risks & Benefits: The UK Experience • 11/2003 simvastatin approved for Behind the Counter use for “Moderate Risk” patients • In the UK “Moderate Risk” = 10%-15% 10 year risk of a first major coronary event (note NCEP Moderate Risk is defined as <10%) • Controversy Continues • ? Update
? Balancing Risks & Benefits: The Underserved • Under treatment for patients with favorable risk/benefit profiles • Marginalizing the Total Lifestyle Change Imperative
Customer Use Study • Although the investigators collected data necessary to evaluate self-rx decision vs. NCEP guidelines the data was not presented and could not be extracted from publically available data. • In addition, the Mrk presentations to the OTC Committee inappropriately collapsed the NCEP Moderate and Moderately High Risk categories they renamed the “Moderate Risk Group”.
? Thoughts The lovastatin OTC request should be denied • The risks of lovastatin OTC are not insignificant and magnified in an unmanaged OTC population • The benefits of lovastatin OTC are uncertain and limited at best • OTC lovastatin is an uncontrolled and ill-begotten public health experiment of unprecedented scale • Approval would be a substantial failure of FDA’s obligation to be an advocate for patient safety
