Osteonecrosis
of the jaw and other oro-facial sites, including the external auditory canal,
have been reported in patients treated
with BONIVA.

Summary
BONIVA
is not indicated for use in women of reproductive potential. There are no data with
BONIVA use in pregnant women to inform any drug-associated risks.
In
reproductive toxicity studies in the rat, BONIVA caused post-implantation loss and
obstruction of labor with maternal and fetal periparturient mortality at greater
than or equal to 3 times human exposure at the recommended 2.5 mg daily oral
dose, or at greater than or
equal to 1 times human
exposure at the recommended
150 mg once-monthly oral dose. In pregnant rats, kidney developmental toxicity
occurred in offspring at greater than or equal to 30 times the daily 2.5 mg human
dose or at greater than or equal to 9 times the once-monthly 150 mg human dose.
In rat reproductive studies, impaired pup neuromuscular development was observed
at 45 times the daily 2.5 mg dose and 13 times the once-monthly 150 mg dose. In
reproductive studies in the rabbit, BONIVA caused maternal mortality at greater
than or equal to 8 times the daily 2.5 mg dose and greater than or equal to 4
times the once-monthly 150 mg dose.
Data
Animal Data
In
female rats given ibandronate at oral doses greater than or equal to 3 times human
exposure at the recommended daily oral dose of 2.5 mg or greater than or equal to
1 times human exposure at the recommended once-monthly oral dose of 150 mg beginning
14 days before mating and continuing through lactation, maternal deaths were observed
at the time of delivery in all dose groups. Perinatal pup loss in dams given doses
producing 45 times human exposure at the recommended daily dose and 13 times human
exposure at the recommended once-monthly dose was likely related to maternal dystocia.
Calcium supplementation did not completely prevent dystocia and periparturient mortality
in any of the treated groups at greater than or equal to
16
times the recommended daily dose and greater than or equal to 4.6 times the recommended
once-monthly dose. A low incidence of postimplantation loss was observed in rats
treated from 14 days before mating throughout lactation or during gestation, only
at doses causing maternal dystocia and periparturient mortality. In pregnant rats
dosed orally from gestation day 17 through lactation day 21 (following closure of
the hard palate through weaning), maternal toxicity, including dystocia and mortality,
fetal perinatal and postnatal mortality, were observed at doses equivalent to human
exposure at the recommended daily dose and greater than or equal to 4 times the
recommended once-monthly dose. Periparturient mortality has also been observed with
other bisphosphonates and appears to be a class effect related to inhibition of
skeletal calcium mobilization resulting in hypocalcemia and dystocia.
Exposure
of pregnant rats during the period of organogenesis resulted in an increased fetal
incidence of RPU (renal pelvis ureter) syndrome at oral doses producing 30 times
human exposure at the recommended daily oral dose of 2.5 mg and greater than or
equal to 9 times human exposure at the recommended once-monthly oral dose of 150
mg. Impaired pup neuromuscular development (cliff avoidance test) was observed at
45 times human exposure at the daily dose and 13 times the once-monthly dose.
In
pregnant rabbits treated orally with ibandronate during gestation at doses greater
than or equal to 8 times the recommended human daily oral dose of 2.5 mg and greater
than or equal to 4 times the recommended human once-monthly oral dose of 150 mg,
dose-related maternal mortality was observed in all treatment groups. The deaths
occurred prior to parturition and were associated with lung edema and hemorrhage.
No significant fetal anomalies were observed.
Exposure
multiples for the rat studies were calculated for the recommended daily oral dose
of 2.5 mg or once- monthly dose of 150 mg based on area under the curve (AUC) comparison.
Exposure multiples for the rabbit study were calculated for the recommended human
daily oral dose of 2.5 mg or once-monthly dose of 150 mg based on dose/body surface
area comparison. Doses used in pregnant animals were 1, 4, 5, 6, 16, 10, 20, 30,
60 or 100 mg/kg/day in rats, and 1, 4 or 20 mg/kg/day in rabbits.

Summary
BONIVA
is not indicated for use in women of reproductive potential. There is no information
on the presence of ibandronate in human milk, the effects of ibandronate on the
breastfed infant, or the effects of ibandronate on milk production. Ibandronate
is present in rat milk (see Data).The
clinical relevance of these data is unclear.
Data
Animal Data
In
lactating rats treated with intravenous doses of 0.08 mg/kg, ibandronate was present
in breast milk from 2 to 24 hours after dose administration. Concentrations in
milk averaged 1.5 times plasma concentrations.

What
is BONIVA?
BONIVA
is a prescription medicine used to treat or prevent osteoporosis in women after
menopause. BONIVA helps increase bone mass and helps reduce the chance of having
a spinal fracture (break).
It
is not known how long BONIVA works for the treatment and prevention of osteoporosis. You should see
your doctor regularly to determine if BONIVA is still right for you...
How should I
take BONIVA?
After
swallowing BONIVA tablet, wait at least 60 minutes:
What are the
possible side effects of BONIVA?
Call
your doctor for medical advice about side effects. You may report side effects to
FDA at 1-800-FDA-1088. You may also report side effects to Genentech at 1-888-835-2555.
