14.2 Prevention of Postmenopausal Osteoporosis

Daily Dosing
The safety and effectiveness of ibandronate sodium 2.5 mg as ibandronic acid daily for the prevention of postmenopausal osteoporosis were demonstrated in a randomized, double-blind, placebo-controlled 2 year study (Prevention Study) of 653 postmenopausal women without osteoporosis at baseline. Women were aged 41 to 82 years, were on average 8.5 years postmenopause, and had lumbar spine BMD T-scores greater than -2.5. Women were stratified according to time since menopause (1 to 3 years, greater than 3 years) and baseline lumbar spine BMD (T-score: greater than -1, -1 to -2.5). The study compared daily ibandronate sodium at three dose levels (0.5 mg, 1 mg, 2.5 mg) with placebo. All women received 500 mg of supplemental calcium per day.

The primary efficacy measure was the change in BMD of lumbar spine after 2 years of treatment. Ibandronate sodium 2.5 mg as ibandronic acid daily resulted in a mean increase in lumbar spine BMD of 3.1% compared with placebo following 2 years of treatment. Increases in BMD were seen at 6 months and at all later time points. Irrespective of the time since menopause or the degree of pre-existing bone loss, treatment with ibandronate sodium resulted in a higher BMD response at the lumbar spine compared with placebo across all four baseline strata [time since menopause (1 to 3 years, greater than 3 years) and baseline lumbar spine BMD (T-score: greater than -1, -1 to -2.5)].

Compared with placebo, treatment with ibandronate sodium 2.5 mg as ibandronic acid daily increased BMD of the total hip by 1.8%, the femoral neck by 2%, and the trochanter by 2.1%.

Once-Monthly Dosing
The safety and effectiveness of ibandronate sodium 150 mg as ibandronic acid once-monthly for the prevention of postmenopausal osteoporosis were demonstrated in a randomized, double-blind, placebo-controlled 1 year study (Monthly Prevention Study) of 160 postmenopausal women with low bone mass at baseline (T-score of -1 to -2.5). Women, aged 46 to 60 years, were on average 5.4 years postmenopause. All women received 400 international units of vitamin D and 500 mg calcium supplementation daily.

The primary efficacy measure was the relative change in BMD at the lumbar spine after 1 year of treatment. Ibandronate sodium 150 mg as ibandronic acid once-monthly resulted in a mean increase in lumbar spine BMD of 4.12% (95% confidence interval 2.96 to 5.28) compared with placebo following 1 year of treatment (p<0.0001), based on a 3.73% and -0.39% mean change in BMD from baseline in the 150 mg once-monthly ibandronate sodium as ibandronic acid and placebo treatment groups, respectively. BMD at other skeletal sites was also increased relative to baseline values.

17 PATIENT COUNSELING INFORMATION

“See FDA-approved patient labeling (Medication Guide)”

17.1 Information for Patients

Instruct patients to read the Medication Guide carefully before taking Ibandronate Sodium Tablets and to re-read it each time the prescription is renewed because it contains important information the patient should know about Ibandronate Sodium Tablets. The Medication Guide also includes the dosing instructions in order to maximize absorption and clinical benefit.

• Ibandronate Sodium Tablet should be taken at least 60 minutes before the first food or drink (other than water) of the day and before taking any oral medication or supplementation including calcium, antacids or vitamins (see DRUG INTERACTIONS [7.1]).

• To facilitate delivery to the stomach, and thus reduce the potential for esophageal irritation, Ibandronate Sodium Tablet should be swallowed whole with a full glass of plain water (6 to 8 oz) while the patient is standing or sitting in an upright position. Patients should not lie down for 60 minutes after taking Ibandronate Sodium Tablet.

• Patients should not eat, drink anything except for water, or take other medications for 60 minutes after taking Ibandronate Sodium Tablet.

• Plain water is the only drink that should be taken with Ibandronate Sodium Tablet. Note that some mineral waters may have a higher concentration of calcium and therefore should not be used.

• Patients should not chew or suck the tablet because of a potential for oropharyngeal ulceration.

• The Ibandronate Sodium Tablet 150 mg (ibandronate) should be taken on the same date each month (i.e., the patient’s Ibandronate Sodium Tablet day).

• The patient must not take two 150 mg tablets within the same week.

• If the once-monthly dose is missed, and the patient’s next scheduled Ibandronate Sodium Tablet day is more than 7 days away, the patient should be instructed to take one Ibandronate Sodium Tablet 150 mg (ibandronate) in the morning following the date that it is remembered (see DOSAGE AND ADMINISTRATION [2.3]). The patient should then return to taking one Ibandronate Sodium Tablet 150 mg (ibandronate) every month in the morning of their chosen day, according to their original schedule.

• If the once-monthly dose is missed, and the patient’s next scheduled Ibandronate Sodium Tablet day is only 1 to 7 days away, the patient must wait until the subsequent month’s scheduled Ibandronate Sodium Tablet day to take their tablet. The patient should then return to taking one Ibandronate Sodium Tablet 150 mg (ibandronate) every month in the morning of their chosen day, according to their original schedule.

Patients should receive supplemental calcium and vitamin D if dietary intake is inadequate. Intake of supplemental calcium and vitamin D should be delayed for at least 60 minutes following oral administration of Ibandronate Sodium Tablet in order to maximize absorption of Ibandronate Sodium Tablets.

Physicians should be alert to signs or symptoms signaling a possible esophageal reaction during therapy, and patients should be instructed to discontinue Ibandronate Sodium Tablets and seek medical attention if they develop symptoms of esophageal irritation such as new or worsening dysphagia, pain on swallowing, retrosternal pain, or heartburn.
