Absolute difference in selected events among women taking EVISTA
In an analysis* of the Multiple Outcome of Raloxifene (MORE) trial, the benefits of EVISTA decreasing vertebral fractures and invasive breast cancer risks were greater than the increase in venous thromboembolism in women with or without baseline vertebral fractures.1
Important considerations
- The recommended dosing of EVISTA in the prescribing information is one 60-mg tablet once a day. The Multiple Outcomes of Raloxifene Evaluation (MORE) trial included a 120 mg/d group. Please note that data from that dose group is not presented
- These charts show 4-year fracture data, while Table 4 of the label shows 3-year fracture data from the MORE trial
- These charts discuss adverse events and other data reported from the trial that may not be consistent with the overall trial database, other EVISTA clinical trials, or postmarketing experience with EVISTA. The full Prescribing Information for EVISTA may reflect additional or different information
- Invasive breast cancer and safety events are presented for patients without or with a vertebral fracture on these charts, while these outcomes are presented for patients pooled together in the label
- Individual results may vary. The risk/benefit assessment should be done on an individual patient basis

Venous thromboembolic event (VTE) facts
Venous thromboembolic event data from the MORE|| clinical trial
- A venous thromboembolic event, such as deep vein thrombosis (DVT) or pulmonary embolism (PE), is a blood clot that originates in the veins. It is not a blood clot that originates in the arterial system
- The most serious adverse reaction to EVISTA was VTE
- During an average study drug exposure of 2.6 years, VTE occurred in about 1 out of 100 patients treated with EVISTA. Highest VTE risk was observed during the first few months of therapy
- Twenty-six women treated with EVISTA had a VTE compared with 11 placebo-treated women. The hazard ratio was 2.4 (95% CI 1.2-4.5)
- EVISTA increased the risk of venous thromboembolism to 2- to 3- fold over placebo in postmenopausal women with osteoporosis whose average age was 67 years3,4

VTEs—safety considerations when screening women for therapy with EVISTA
- Women with active or past history of VTEs should NOT be prescribed EVISTA
- In clinical trials, women treated with EVISTA had an increased risk of VTEs. The greatest risk for DVT and PE occurs within the first 4 months
- Because immobilization increases the risk for VTEs, EVISTA should be discontinued at least 72 hours prior to and during prolonged immobilization. Therapy with EVISTA should be resumed only after the patient is fully ambulatory. In addition, women should be advised to move around periodically during prolonged travel. The risk-benefit balance should be considered in women at risk for thromboembolic disease for other reasons, such as CHF, superficial thrombophlebitis, and active malignancy
Increased risk of DVT and PE has been reported with EVISTA use. EVISTA is contraindicated in women with active or past history of VTE, including DVT, PE, and retinal vein thrombosis.
