4 Why Pre-specify Incident Venous Thromboembolism?
JUPITER Why Pre-specify Incident Venous Thromboembolism? Venous and arterial thrombosis are common, serious, age-related events that often co-occur and share some risk factors Controversies persist regarding the nature and extent of their shared pathways and whether treatments of demonstrated efficacy for one condition have consistent benefits for the primary or secondary prevention of the other Benefits of statins might accrue not only through effects on lipids but also through influence on thrombosis and inflammation. Specifically, statins downregulate the blood coagulation cascade through decreased tissue factor expression, which leads to reduced thrombin formation* *Undas, Brummel-Ziedins, Mann. ATVB 2005;25:

5 Observational studies of statins & VTE

WHS: Risk of ischemic stroke for those in the highest versus the lowest tertile. ARIC: Risk of ischemic stroke for those in the CDC/AHA defined high risk category (CRP > 3.0 mg/L) versus those in the CDC/AHA low risk category (CRP < 1.0 mg/L). Rotterdam study: top vs bottom quartile for total stroke (similar results for ischemic and hemorrhagic stroke).

6 JUPITER Why Pre-specify Incident Venous Thromboembolism? Observational Evidence: In non-randomized cohort and case-control studies and registries, statins have often, but not always, been associated with reduced risk of VTE. These studies cannot exclude indication bias. Many included prevalent statin users, and poor health affects the decision to initiate and persist in therapy. They also did not consider the possibility that the reduction in VTE events is secondary to a statin-induced reduction in arterial hospitalizations. Similar evidence from observational studies indicated benefits for statins on mortality in heart failure, but trials (CORONA, GISSI) refuted this hypothesis Clear need for a prospective randomized trial

8 JUPITER Symptomatic VTE Symptomatic venous thromboembolism was a pre-specified secondary end point Upon identification of a new VTE case, site investigators indicated the source of confirmation (venous ultrasonogram or venogram for DVT; angiogram, CT scan, or ventilation-perfusion scan for PE) Initiation and indication for anticoagulation therapy also noted Unprovoked VTE: no trauma, hospitalization, or surgery within 3 months before diagnosis, and no malignancy diagnosed before or up to 3 months after the VTE Unprovoked and provoked VTE, pulmonary embolism and deep vein thrombosis alone were tertiary end points.

9 JUPITER VTE analysis Primary efficacy analyses counted all events diagnosed by March 30, 2008 according to the intention to treat principle Safety analyses also included additional events before the closeout visit and unblinding Competing risks analyses compared effects of rosuvastatin on first VTE versus first primary cardiovascular event Estimates of net clinical benefits considered the impact on the number needed to treat (NNT) of inclusion of VTE in a composite with the primary cardiovascular event, and also with total mortality

21 JUPITER VTE in JUPITER: Conclusions VTE is a serious event that occurred about as often as MI and stroke in the JUPITER study Rosuvastatin was associated with a significant 43 percent reduction in risk of VTE with no increase in bleeding. This benefit was comparable in magnitude and independent of the effect on arterial events Widening the treatment target to include prevention of VTE and death in addition to arterial thrombosis increases the estimated benefit of statin use
