Warnings and Precautions
5.4 Premenopausal Use
(additions
underlined)
There is no indication for premenopausal use of EVISTA.
Safety of EVISTA in premenopausal women has not been established and its use is
not recommended. Additionally, there is concern regarding inadvertent drug
exposure in pregnancy in women of reproductive potential who become pregnant,
due to risk of fetal harm.

Adverse Reactions
6.1 Clinical Trials Experience
(additions
underlined)
Because clinical studies are conducted under widely
varying conditions, adverse reaction rates observed in the clinical trials of a
drug cannot be directly compared to rates in the clinical trials of another
drug and may not reflect the rates observed in practice.
The data described below reflect exposure to EVISTA in 8429
patients who were enrolled in placebo-controlled trials,
including 6666 exposed for 1 year and 5685 for at least 3 years.

Placebo-Controlled Trial of Postmenopausal
Women at Increased Risk for Major Coronary Events (RUTH) — The
safety of EVISTA (60 mg once daily) was assessed in a placebo-controlled
multinational trial of 10,101 postmenopausal women (age range 55-92) with
documented coronary heart disease (CHD) or multiple CHD risk factors. Median
study drug exposure was 5.1 years for both treatment groups. Therapy was
discontinued due to an adverse reaction in 25% of 5044 EVISTA-treated women and
24% of 5057 placebo-treated women. The incidence per year of all-cause
mortality was similar between the raloxifene (2.07%) and placebo (2.25%)
groups.
Adverse reactions reported more frequently in
EVISTA-treated women than in placebo-treated women included peripheral edema
(14.1% raloxifene versus 11.7% placebo), muscle spasms/leg cramps (12.1%
raloxifene versus 8.3% placebo), hot flashes (7.8% raloxifene versus 4.7%
placebo), venous thromboembolic events (2.0% raloxifene versus 1.4% placebo),
and cholelithiasis (3.3% raloxifene versus 2.6% placebo).
Tamoxifen-Controlled Trial of Postmenopausal
W omen at Increased Risk for Invasive Breast Cancer (STAR) — The safety of
EVISTA 60 mg/day versus tamoxifen 20 mg/day over 5 years was assessed in 19,747
postmenopausal women (age range 35-83 years) in a randomized, double-blind
trial. As of 31 December 2005, the median follow-up was 4.3 years. The safety
profile of raloxifene was similar to that in the placebo-controlled raloxifene
trials.

Use in Specific Populations
8.1 Pregnancy
(PLLR
conversion)
EVISTA is contraindicated for use in pregnant women, and
is not indicated for use in females of reproductive potential. Based on
mechanism of action, EVISTA may block the important functions that estrogen has
during all stages of pregnancy [see
Clinical Pharmacology (12.1)]. Limited data with EVISTA use in pregnant
women are insufficient to inform any drug associated risks for births defects
or miscarriage.
In rabbits and rats dosed during organogenesis or during
gestation and lactation, EVISTA produced multiple adverse reproductive and
developmental effects, including abortion; fetal anomalies; and delayed or
disrupted parturition leading to maternal and neonatal mortality, at doses less
than or similar to the maximum recommended human dose (based on human body
surface area comparison).
Data
Animal
Data
In the developmental and reproductive toxicity studies
conducted with EVISTA, numerous adverse effects were observed in multiple
animal species. In rabbits dosed during organogenesis, abortion and a low rate of
fetal heart anomalies (ventricular septal defects) occurred at doses ?0.1 mg/kg
(?0.04 times the human dose based on surface area, mg/m2). In rats dosed during
organogenesis, retardation of fetal growth and developmental abnormalities
(wavy ribs, kidney cavitation) occurred at doses ?1 mg/kg (?0.2 times the human
dose based on surface area, mg/m2). Treatment of rats during gestation and
lactation with doses of 0.1 to 10 mg/kg (0.02 to 1.6 times the human dose based
on surface area, mg/m2) produced effects
that included delayed and disrupted parturition, decreased neonatal survival
and altered physical development, sex- and age-specific reductions in growth
and changes in pituitary hormone content, and decreased lymphoid compartment
size in offspring. At 10 mg/kg, the disruption of parturition resulted in
maternal and progeny morbidity and death. Effects in adult offspring (4 months
of age) included uterine hypoplasia and reduced fertility; however, no ovarian
or vaginal pathology was observed.
8.2Lactation
(PLLR
conversion)
Risk Summary
EVISTA is not indicated for use in females of
reproductive potential. There is no information on the presence of raloxifene
in human milk, the effects on the breastfed child, or the effects on milk
production. However, based on mechanism of action, EVISTA may block the
important functions that estrogen has in mammary tissue during lactation.

Reduction in Risk of
Invasive Breast Cancer in Postmenopausal Women with Osteoporosis or at High Risk
of Invasive Breast Cancer
(new
subsection added)
Use of EVISTA is associated
with the reduction of the risk of invasive breast cancer in postmenopausal
women. EVISTA has not been shown to reduce the risk of noninvasive breast
cancer. When considering treatment, physicians need to discuss the potential
benefits and risks of EVISTA treatment with the patient.
EVISTA is not indicated for the
treatment of invasive breast cancer or reduction of the risk of recurrence.
Patients should have breast
exams and mammograms before starting EVISTA and should continue regular breast
exams and mammograms in keeping with good medical practice after beginning
treatment with EVISTA.
