Overdosage of IBANDRONATE SODIUM
Information about signs, symptoms, and laboratory findings of acute ovedosage and the general principles of overdose treatment.10 OVERDOSAGE No specific information is available on the treatment of overdosage of ibandronate sodium tablets. However, based on knowledge of this class of compounds, oral overdosage may result in hypocalcemia, hypophosphatemia, and upper gastrointestinal adverse events, such as upset stomach, dyspepsia, esophagitis, gastritis, or ulcer. Milk or antacids should be given to bind ibandronate sodium tablets. Due to the risk of esophageal irritation, vomiting should not be induced, and the patient should remain fully upright. Dialysis would not be beneficial.
Adverse reactions
Information about undesirable effects, reasonably associated with use of the drug, that may occur as part of the pharmacological action of the drug or may be unpredictable in its occurrence. Adverse reactions include those that occur with the drug, and if applicable, with drugs in the same pharmacologically active and chemically related class. There is considerable variation in the listing of adverse reactions. They may be categorized by organ system, by severity of reaction, by frequency, by toxicological mechanism, or by a combination of these.6 ADVERSE REACTIONS The most common adverse reactions (greater than 5%) are back pain, dyspepsia, pain in extremity, diarrhea, headache, and myalgia. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Apotex Corp. at 1-800-706-5575 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials 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. Treatment and Prevention of Postmenopausal Osteoporosis Daily Dosing The safety of ibandronate sodium tablets 2.5 mg once daily in the treatment and prevention of postmenopausal osteoporosis was assessed in 3577 patients aged 41 – 82 years. The duration of the trials was 2 to 3 years, with 1134 patients exposed to placebo and 1140 exposed to ibandronate sodium tablets 2.5 mg. Patients with pre-existing gastrointestinal disease and concomitant use of non-steroidal anti-inflammatory drugs, proton pump inhibitors and H2 antagonists were included in these clinical trials. All patients received 500 mg calcium plus 400 international units vitamin D supplementation daily. The incidence of all-cause mortality was 1% in the placebo group and 1.2% in the ibandronate sodium tablets 2.5 mg daily group. The incidence of serious adverse reactions was 20% in the placebo group and 23% in the ibandronate sodium tablets 2.5 mg daily group. The percentage of patients who withdrew from treatment due to adverse reactions was approximately 17% in both the ibandronate sodium tablets 2.5 mg daily group and the placebo group. Table 1 lists adverse reactions from the treatment and prevention studies reported in greater than or equal to 2% of patients and more frequently in patients treated daily with ibandronate sodium tablets than patients treated with placebo. Table 1 Adverse Reactions Occurring at an Incidence Greater Than or Equal to 2% and in More Patients Treated with Ibandronate Sodium Tablets Than in Patients Treated with Placebo Daily in the Osteoporosis Treatment and Prevention Studies Body System Placebo % (n=1134) Ibandronate Sodium Tablets 2.5 mg % (n=1140) Body as a Whole Back Pain 12 14 Pain in Extremity 6 8 Asthenia 2 4 Allergic Reaction 2 3 Digestive System Dyspepsia 10 12 Diarrhea 5 7 Tooth Disorder 2 4 Vomiting 2 3 Gastritis 2 2 Musculoskeletal System Myalgia 5 6 Joint Disorder 3 4 Arthritis 3 3 Nervous System Headache 6 7 Dizziness 3 4 Vertigo 3 3 Respiratory System Upper Respiratory Infection 33 34 Bronchitis 7 10 Pneumonia 4 6 Pharyngitis 2 3 Urogenital System Urinary Tract Infection 4 6 Gastrointestinal Adverse Reactions The incidence of selected gastrointestinal adverse reactions in the placebo and ibandronate sodium tablets 2.5 mg daily groups were: dyspepsia (10% vs. 12%), diarrhea (5% vs. 7%), and abdominal pain (5% vs. 6%). Musculoskeletal Adverse Reactions The incidence of selected musculoskeletal adverse reactions in the placebo and ibandronate sodium tablets 2.5 mg daily groups were: back pain (12% vs. 14%), arthralgia (14% vs. 14%) and myalgia (5% vs. 6%). Ocular Adverse Events Reports in the medical literature indicate that bisphosphonates may be associated with ocular inflammation such as iritis and scleritis. In some cases, these events did not resolve until the bisphosphonate was discontinued. There were no reports of ocular inflammation in studies with ibandronate sodium tablets 2.5 mg daily. Monthly Dosing The safety of ibandronate sodium tablets 150 mg once monthly in the treatment of postmenopausal osteoporosis was assessed in a two year trial which enrolled 1583 patients aged 54 to 81 years, with 395 patients exposed to ibandronate sodium tablets 2.5 mg daily and 396 exposed to ibandronate sodium tablets 150 mg monthly. Patients with active or significant pre-existing gastrointestinal disease were excluded from this trial. Patients with dyspepsia or concomitant use of non-steroidal anti-inflammatory drugs, proton pump inhibitors and H2 antagonists were included in this study. All patients received 500 mg calcium plus 400 international units vitamin D supplementation daily. After one year, the incidence of all-cause mortality was 0.3% in both the ibandronate sodium tablets 2.5 mg daily group and the ibandronate sodium tablets 150 mg monthly group. The incidence of serious adverse events was 5% in the ibandronate sodium tablets 2.5 mg daily group and 7% in the ibandronate sodium tablets 150 mg monthly group. The percentage of patients who withdrew from treatment due to adverse events was 9% in the ibandronate sodium tablets 2.5 mg daily group and 8% in the ibandronate sodium tablets 150 mg monthly group. Table 2 lists the adverse events reported in greater than or equal to 2% of patients.

Musculoskeletal Adverse Events The incidence of adverse events in the ibandronate sodium tablets 2.5 mg daily and ibandronate sodium tablets 150 mg monthly groups were: back pain (4% vs. 5%), arthralgia (4% vs. 6%) and myalgia (1% vs. 2%). Acute Phase Reactions Symptoms consistent with acute phase reactions have been reported with bisphosphonate use. Over the two years of the study, the overall incidence of acute phase reaction symptoms was 3% in the ibandronate sodium tablets 2.5 mg daily group and 9% in the ibandronate sodium tablets 150 mg monthly group. These incidence rates are based on the reporting of any of 33 acute-phase reaction like symptoms within 3 days of the monthly dosing and lasting 7 days or less. Influenza like illness was reported in no patients in the ibandronate sodium tablets 2.5 mg daily group and 2% in the ibandronate sodium tablets 150 mg monthly group. Ocular Adverse Events Two patients who received ibandronate sodium tablets 150 mg once-monthly experienced ocular inflammation, one was a case of uveitis and the other scleritis. One hundred sixty (160) postmenopausal women without osteoporosis participated in a 1-year, double-blind, placebo-controlled study of ibandronate sodium tablets 150 mg once-monthly for prevention of bone loss. Seventy-seven subjects received ibandronate sodium tablets and 83 subjects received placebo. The overall pattern of adverse events was similar to that previously observed. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of ibandronate sodium tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Hypersensitivity Allergic reactions including anaphylactic reaction/shock with fatalities, angioedema, bronchospasm, asthma exacerbations, rash, Stevens-Johnson syndrome, erythema multiforme, and dermatitis bullous have been reported (see CONTRAINDICATIONS [4] ) . Hypocalcemia Hypocalcemia has been reported in patients treated with ibandronate sodium tablets (see WARNINGS AND PRECAUTIONS [5.2] ) . Musculoskeletal Pain Bone, joint, or muscle pain (musculoskeletal pain), described as severe or incapacitating, has been reported (see WARNINGS AND PRECAUTIONS [5.3] ) . Jaw Osteonecrosis Osteonecrosis of the jaw and other oro-facial sites, including the external auditory canal, have been reported in patients treated with ibandronate sodium tablets (see WARNINGS AND PRECAUTIONS [5.4] ) . Atypical Femoral Shaft Fracture Atypical, low-energy, or low-trauma fractures of the femoral shaft ( see WARNINGS AND PRECAUTIONS [5.5] ).

IBANDRONATE SODIUM Drug Interactions
Information about and practical guidance on preventing clinically significant drug/drug and drug/food interactions that may occur in people taking the drug.7 DRUG INTERACTIONS Calcium supplements, antacids and some oral medications may interfere with absorption of ibandronate. Do not take within 60 minutes of dosing ( 7.1 ) Use caution when co-prescribing aspirin/nonsteroidal anti-inflammatory drugs that may worsen gastrointestinal irritation. ( 7.2 ) 7.1 Calcium Supplements/Antacids Products containing calcium and other multivalent cations (such as aluminum, magnesium, iron) are likely to interfere with absorption of ibandronate sodium tablets. Therefore, instruct patients to take ibandronate sodium tablets at least 60 minutes before any oral medications, including medications containing multivalent cations (such as antacids, supplements or vitamins). Also, patients should wait at least 60 minutes after dosing before taking any other oral medications ( see DOSAGE AND ADMINISTRATION [2.3] ). 7.2 Aspirin/Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) Because aspirin, NSAIDs, and bisphosphonates are all associated with gastrointestinal irritation, caution should be exercised in the concomitant use of aspirin or NSAIDs with ibandronate sodium tablets. 7.3 H2 Blockers In healthy volunteers, co-administration with ranitidine resulted in a 20% increased bioavailability of ibandronate, which was not considered to be clinically relevant (see CLINICAL PHARMACOLOGY [12.3] ) . 7.4 Drug/Laboratory Test Interactions Bisphosphonates are known to interfere with the use of bone-imaging agents. Specific studies with ibandronate have not been performed.

Clinical pharmacology
Information about the clinical pharmacology and actions of the drug in humans.12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action The action of ibandronate on bone tissue is based on its affinity for hydroxyapatite, which is part of the mineral matrix of bone. Ibandronate inhibits osteoclast activity and reduces bone resorption and turnover. In postmenopausal women, it reduces the elevated rate of bone turnover, leading to, on average, a net gain in bone mass. 12.2 Pharmacodynamics Osteoporosis is characterized by decreased bone mass and increased fracture risk, most commonly at the spine, hip, and wrist. The diagnosis can be confirmed by a finding of low bone mass, evidence of fracture on x-ray, a history of osteoporotic fracture, or height loss or kyphosis indicative of vertebral fracture. While osteoporosis occurs in both men and women, it is most common among women following menopause. In healthy humans, bone formation and resorption are closely linked; old bone is resorbed and replaced by newly formed bone. In postmenopausal osteoporosis, bone resorption exceeds bone formation, leading to bone loss and increased risk of fracture. After menopause, the risk of fractures of the spine and hip increases; approximately 40% of 50-year-old women will experience an osteoporosis-related fracture during their remaining lifetimes. Ibandronate sodium tablets produced biochemical changes indicative of dose-dependent inhibition of bone resorption, including decreases of biochemical markers of bone collagen degradation (such as deoxypyridinoline, and cross-linked C-telopeptide of Type I collagen) in the daily dose range of 0.25 mg to 5 mg and once-monthly doses from 100 mg to 150 mg in postmenopausal women. Treatment with 2.5 mg daily ibandronate sodium tablets resulted in decreases in biochemical markers of bone turnover, including urinary C-terminal telopeptide of Type I collagen (uCTX) and serum osteocalcin, to levels similar to those in premenopausal women. Changes in markers of bone formation were observed later than changes in resorption markers, as expected, due to the coupled nature of bone resorption and formation. Treatment with 2.5 mg daily ibandronate sodium tablets decreased levels of uCTX within 1 month of starting treatment and decreased levels of osteocalcin within 3 months. Bone turnover markers reached a nadir of approximately 64% below baseline values by 6 months of treatment and remained stable with continued treatment for up to 3 years. Following treatment discontinuation, there is a return to pretreatment baseline rates of elevated bone resorption associated with postmenopausal osteoporosis. In a 1-year, study comparing once-monthly vs. once-daily oral dosing regimens, the median decrease from baseline in serum CTX values was -76% for patients treated with the 150 mg once-monthly regimen and -67% for patients treated with the 2.5 mg daily regimen. In a 1-year, prevention study comparing ibandronate sodium tablets 150 mg once-monthly to placebo, the median placebo-subtracted decrease in sCTX was -49.8%. 12.3 Pharmacokinetics Absorption The absorption of oral ibandronate occurs in the upper gastrointestinal tract. Plasma concentrations increase in a dose-linear manner up to 50 mg oral intake and increases nonlinearly above this dose. Following oral dosing, the time to maximum observed plasma ibandronate concentrations ranged from 0.5 to 2 hours (median 1 hour) in fasted healthy postmenopausal women. The mean oral bioavailability of 2.5 mg ibandronate was about 0.6% compared to intravenous dosing. The extent of absorption is impaired by food or beverages (other than plain water). The oral bioavailability of ibandronate is reduced by about 90% when ibandronate sodium tablets are administered concomitantly with a standard breakfast in comparison with bioavailability observed in fasted subjects. There is no meaningful reduction in bioavailability when ibandronate is taken at least 60 minutes before a meal. However, both bioavailability and the effect on bone mineral density (BMD) are reduced when food or beverages are taken less than 60 minutes following an ibandronate dose. Distribution After absorption, ibandronate either rapidly binds to bone or is excreted into urine. In humans, the apparent terminal volume of distribution is at least 90 L, and the amount of dose removed from the circulation via the bone is estimated to be 40% to 50% of the circulating dose. In vitro protein binding in human serum was 99.5% to 90.9% over an ibandronate concentration range of 2 to 10 ng/mL in one study and approximately 85.7% over a concentration range of 0.5 to 10 ng/mL in another study. Metabolism Ibandronate does not undergo hepatic metabolism and does not inhibit the hepatic cytochrome P450 system. Ibandronate is eliminated by renal excretion. Based on a rat study, the ibandronate secretory pathway does not appear to include known acidic or basic transport systems involved in the excretion of other drugs. There is no evidence that ibandronate is metabolized in humans. Elimination The portion of ibandronate that is not removed from the circulation via bone absorption is eliminated unchanged by the kidney (approximately 50% to 60% of the absorbed dose). Unabsorbed ibandronate is eliminated unchanged in the feces. The plasma elimination of ibandronate is multiphasic. Its renal clearance and distribution into bone accounts for a rapid and early decline in plasma concentrations, reaching 10% of the C max within 3 or 8 hours after intravenous or oral administration, respectively. This is followed by a slower clearance phase as ibandronate redistributes back into the blood from bone. The observed apparent terminal half-life for ibandronate is generally dependent on the dose studied and on assay sensitivity. The observed apparent terminal half-life for the 150 mg ibandronate tablet upon oral administration to healthy postmenopausal women ranges from 37 to 157 hours. Total clearance of ibandronate is low, with average values in the range 84 to 160 mL/min. Renal clearance (about 60 mL/min in healthy postmenopausal females) accounts for 50% to 60% of total clearance and is related to creatinine clearance. The difference between the apparent total and renal clearances likely reflects bone uptake of the drug. Specific Populations Pediatrics The pharmacokinetics of ibandronate has not been studied in patients less than 18 years of age. Geriatric Because ibandronate is not known to be metabolized, the only difference in ibandronate elimination for geriatric patients versus younger patients is expected to relate to progressive age-related changes in renal function. Gender The bioavailability and pharmacokinetics of ibandronate are similar in both men and women. Race Pharmacokinetic differences due to race have not been studied. Renal Impairment Renal clearance of ibandronate in patients with various degrees of renal impairment is linearly related to creatinine clearance (CLcr). Following a single dose of 0.5 mg ibandronate by intravenous administration, patients with CLcr 40 to 70 mL/min had 55% higher exposure (AUC ∞ ) than the exposure observed in subjects with CLcr greater than 90 mL/min. Patients with CLcr less than 30 mL/min had more than a two-fold increase in exposure compared to the exposure for healthy subjects (see DOSAGE AND ADMINISTRATION [2.4] ) . Hepatic Impairment No studies have been performed to assess the pharmacokinetics of ibandronate in patients with hepatic impairment because ibandronate is not metabolized in the human liver. Drug Interaction Studies Products containing calcium and other multivalent cations (such as aluminum, magnesium, iron), including milk, food, and antacids are likely to interfere with absorption of ibandronate, which is consistent with findings in animal studies. H2 Blockers A pharmacokinetic interaction study in healthy volunteers demonstrated that 75 mg ranitidine (25 mg injected intravenously 90 and 15 minutes before and 30 minutes after ibandronate administration) increased the oral bioavailability of 10 mg ibandronate by about 20%. This degree of increase is not considered to be clinically relevant.
Mechanism of action
Information about the established mechanism(s) of the drugÕs action in humans at various levels (for example receptor, membrane, tissue, organ, whole body). If the mechanism of action is not known, this field contains a statement about the lack of information.12.1 Mechanism of Action The action of ibandronate on bone tissue is based on its affinity for hydroxyapatite, which is part of the mineral matrix of bone. Ibandronate inhibits osteoclast activity and reduces bone resorption and turnover. In postmenopausal women, it reduces the elevated rate of bone turnover, leading to, on average, a net gain in bone mass.
Pharmacodynamics
Information about any biochemical or physiologic pharmacologic effects of the drug or active metabolites related to the drugÕs clinical effect in preventing, diagnosing, mitigating, curing, or treating disease, or those related to adverse effects or toxicity.12.2 Pharmacodynamics Osteoporosis is characterized by decreased bone mass and increased fracture risk, most commonly at the spine, hip, and wrist. The diagnosis can be confirmed by a finding of low bone mass, evidence of fracture on x-ray, a history of osteoporotic fracture, or height loss or kyphosis indicative of vertebral fracture. While osteoporosis occurs in both men and women, it is most common among women following menopause. In healthy humans, bone formation and resorption are closely linked; old bone is resorbed and replaced by newly formed bone. In postmenopausal osteoporosis, bone resorption exceeds bone formation, leading to bone loss and increased risk of fracture. After menopause, the risk of fractures of the spine and hip increases; approximately 40% of 50-year-old women will experience an osteoporosis-related fracture during their remaining lifetimes. Ibandronate sodium tablets produced biochemical changes indicative of dose-dependent inhibition of bone resorption, including decreases of biochemical markers of bone collagen degradation (such as deoxypyridinoline, and cross-linked C-telopeptide of Type I collagen) in the daily dose range of 0.25 mg to 5 mg and once-monthly doses from 100 mg to 150 mg in postmenopausal women. Treatment with 2.5 mg daily ibandronate sodium tablets resulted in decreases in biochemical markers of bone turnover, including urinary C-terminal telopeptide of Type I collagen (uCTX) and serum osteocalcin, to levels similar to those in premenopausal women. Changes in markers of bone formation were observed later than changes in resorption markers, as expected, due to the coupled nature of bone resorption and formation. Treatment with 2.5 mg daily ibandronate sodium tablets decreased levels of uCTX within 1 month of starting treatment and decreased levels of osteocalcin within 3 months. Bone turnover markers reached a nadir of approximately 64% below baseline values by 6 months of treatment and remained stable with continued treatment for up to 3 years. Following treatment discontinuation, there is a return to pretreatment baseline rates of elevated bone resorption associated with postmenopausal osteoporosis. In a 1-year, study comparing once-monthly vs. once-daily oral dosing regimens, the median decrease from baseline in serum CTX values was -76% for patients treated with the 150 mg once-monthly regimen and -67% for patients treated with the 2.5 mg daily regimen. In a 1-year, prevention study comparing ibandronate sodium tablets 150 mg once-monthly to placebo, the median placebo-subtracted decrease in sCTX was -49.8%.
Pharmacokinetics
Information about the clinically significant pharmacokinetics of a drug or active metabolites, for instance pertinent absorption, distribution, metabolism, and excretion parameters.12.3 Pharmacokinetics Absorption The absorption of oral ibandronate occurs in the upper gastrointestinal tract. Plasma concentrations increase in a dose-linear manner up to 50 mg oral intake and increases nonlinearly above this dose. Following oral dosing, the time to maximum observed plasma ibandronate concentrations ranged from 0.5 to 2 hours (median 1 hour) in fasted healthy postmenopausal women. The mean oral bioavailability of 2.5 mg ibandronate was about 0.6% compared to intravenous dosing. The extent of absorption is impaired by food or beverages (other than plain water). The oral bioavailability of ibandronate is reduced by about 90% when ibandronate sodium tablets are administered concomitantly with a standard breakfast in comparison with bioavailability observed in fasted subjects. There is no meaningful reduction in bioavailability when ibandronate is taken at least 60 minutes before a meal. However, both bioavailability and the effect on bone mineral density (BMD) are reduced when food or beverages are taken less than 60 minutes following an ibandronate dose. Distribution After absorption, ibandronate either rapidly binds to bone or is excreted into urine. In humans, the apparent terminal volume of distribution is at least 90 L, and the amount of dose removed from the circulation via the bone is estimated to be 40% to 50% of the circulating dose. In vitro protein binding in human serum was 99.5% to 90.9% over an ibandronate concentration range of 2 to 10 ng/mL in one study and approximately 85.7% over a concentration range of 0.5 to 10 ng/mL in another study. Metabolism Ibandronate does not undergo hepatic metabolism and does not inhibit the hepatic cytochrome P450 system. Ibandronate is eliminated by renal excretion. Based on a rat study, the ibandronate secretory pathway does not appear to include known acidic or basic transport systems involved in the excretion of other drugs. There is no evidence that ibandronate is metabolized in humans. Elimination The portion of ibandronate that is not removed from the circulation via bone absorption is eliminated unchanged by the kidney (approximately 50% to 60% of the absorbed dose). Unabsorbed ibandronate is eliminated unchanged in the feces. The plasma elimination of ibandronate is multiphasic. Its renal clearance and distribution into bone accounts for a rapid and early decline in plasma concentrations, reaching 10% of the C max within 3 or 8 hours after intravenous or oral administration, respectively. This is followed by a slower clearance phase as ibandronate redistributes back into the blood from bone. The observed apparent terminal half-life for ibandronate is generally dependent on the dose studied and on assay sensitivity. The observed apparent terminal half-life for the 150 mg ibandronate tablet upon oral administration to healthy postmenopausal women ranges from 37 to 157 hours. Total clearance of ibandronate is low, with average values in the range 84 to 160 mL/min. Renal clearance (about 60 mL/min in healthy postmenopausal females) accounts for 50% to 60% of total clearance and is related to creatinine clearance.

Dosage and administration
Information about the drug product’s dosage and administration recommendations, including starting dose, dose range, titration regimens, and any other clinically sigificant information that affects dosing recommendations.2 DOSAGE AND ADMINISTRATION Take one 150 mg tablet once monthly on the same day each month ( 2.1 ) Instruct patient to: ( 2.2 ) Swallow whole tablet with 6 to 8 oz of plain water only, at least 60 minutes before the first food, beverage, or medication of day. Avoid lying down for at least 60 minutes after taking ibandronate sodium tablets. Do not eat, drink (except for water), or take other medication for 60 minutes after taking ibandronate sodium tablets. Take supplemental calcium and vitamin D if dietary intake inadequate ( 2.3 ) 2.1 Dosage Information The dose of ibandronate sodium tablet is one 150 mg tablet taken once monthly on the same date each month. 2.2 Important Administration Instructions Instruct Patients to do the following: Take ibandronate sodium tablets at least 60 minutes before the first food or drink (other than water) of the day or before taking any oral medication or supplementation, including calcium, antacids, or vitamins to maximize absorption and clinical benefit, (see DRUG INTERACTIONS [7.1] ) . Avoid the use of water with supplements including mineral water because they may have a higher concentration of calcium. Swallow ibandronate sodium tablets whole with a full glass of plain water (6 to 8 oz) while standing or sitting in an upright position to reduce the potential for esophageal irritation. Avoid lying down for 60 minutes after taking ibandronate sodium tablets (see WARNINGS AND PRECAUTIONS [5.1] ). Do not chew or suck the tablet because of a potential for oropharyngeal ulceration. Do not eat, drink anything except plain water, or take other medications for at least 60 minutes after taking ibandronate sodium tablets. 2.3 Recommendations for Calcium and Vitamin D Supplementation Instruct patients to take supplemental calcium and vitamin D if their dietary intake is inadequate. Avoid the use of calcium supplements within 60 minutes of ibandronate sodium administration because co-administration of ibandronate sodium tablets and calcium may interfere with the absorption of ibandronate sodium (see DRUG INTERACTIONS [7.1] ) . 2.4 Administration Instructions for Missed Once-Monthly Doses If the once-monthly dose is missed, instruct patients to do the following: If the next scheduled ibandronate sodium tablet day is more than 7 days away, take one ibandronate sodium 150 mg tablet in the morning following the date that it is remembered. If the next scheduled ibandronate sodium tablets day is only 1 to 7 days away, wait until the subsequent month’s scheduled ibandronate sodium tablet day to take their tablet. For subsequent monthly doses for both of the above scenarios, instruct patients to return to their original schedule by taking one ibandronate sodium 150 mg tablet every month on their previous chosen day.

Carcinogenesis and mutagenesis and impairment of fertility
Information about carcinogenic, mutagenic, or fertility impairment potential revealed by studies in animals. Information from human data about such potential is part of the warnings field.13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis In a 104-week carcinogenicity study, doses of 3, 7, or 15 mg/kg/day were administered by oral gavage to male and female Wistar rats (systemic exposures up to 12 and 7 times, respectively, human exposure at the recommended daily oral dose of 2.5 mg, and cumulative exposures up to 3.5 and 2 times, respectively, human exposure at the recommended once-monthly oral dose of 150 mg, based on AUC comparison). There were no significant drug-related tumor findings in male or female rats. In a 78-week carcinogenicity study, doses of 5, 20, or 40 mg/kg/day were administered by oral gavage to male and female NMRI mice (exposures up to 475 and 70 times, respectively, human exposure at the recommended daily oral dose of 2.5 mg and cumulative exposures up to 135 and 20 times, respectively, human exposure at the recommended once-monthly oral dose of 150 mg, based on AUC comparison). There were no significant drug-related tumor findings in male or female mice. In a 90-week carcinogenicity study, doses of 5, 20, or 80 mg/kg/day were administered in the drinking water to NMRI mice (cumulative monthly exposures in males and females up to 70 and 115 times, respectively, human exposure at the recommended dose of 150 mg, based on AUC comparison). A dose-related increased incidence of adrenal subcapsular adenoma/carcinoma was observed in female mice, which was statistically significant at 80 mg/kg/day (220 to 400 times human exposure at the recommended daily oral dose of 2.5 mg and 115 times human exposure at the recommended once-monthly oral dose of 150 mg, based on AUC comparison). The relevance of these findings to humans is unknown. Mutagenesis There was no evidence for a mutagenic or clastogenic potential of ibandronate in the following assays: in vitro bacterial mutagenesis assay in Salmonella typhimurium and Escherichia coli (Ames test), mammalian cell mutagenesis assay in Chinese hamster V79 cells, and chromosomal aberration test in human peripheral lymphocytes, each with and without metabolic activation. Ibandronate was not genotoxic in the in vivo mouse micronucleus tests for chromosomal damage. Impairment of Fertility In female rats treated from 14 days prior to mating through gestation, decreases in fertility, corpora lutea, and implantation sites were observed at an oral dose of 16 mg/kg/day (45 times human exposure at the recommended daily oral dose of 2.5 mg and 13 times human exposure at the recommended once-monthly oral dose of 150 mg, based on AUC comparison).
Nonclinical toxicology
Information about toxicology in non-human subjects.13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis In a 104-week carcinogenicity study, doses of 3, 7, or 15 mg/kg/day were administered by oral gavage to male and female Wistar rats (systemic exposures up to 12 and 7 times, respectively, human exposure at the recommended daily oral dose of 2.5 mg, and cumulative exposures up to 3.5 and 2 times, respectively, human exposure at the recommended once-monthly oral dose of 150 mg, based on AUC comparison).

In the Schenk assay in growing rats, ibandronate inhibited bone resorption and increased bone volume, based on histologic examination of the tibial metaphyses. There was no evidence of impaired mineralization at the highest dose of 5 mg/kg/day (subcutaneously), which is 1000 times the lowest antiresorptive dose of 0.005 mg/kg/day in this model, and 5000 times the optimal antiresorptive dose of 0.001 mg/kg/day in the aged ovariectomized rat. This indicates that ibandronate sodium tablets administered at therapeutic doses is unlikely to induce osteomalacia. Long-term daily or once-monthly intermittent administration of ibandronate to ovariectomized rats or monkeys was associated with suppression of bone turnover and increases in bone mass. In both rats and monkeys, vertebral BMD, trabecular density, and biomechanical strength were increased dose-dependently at doses up to 15 times the recommended human daily oral dose of 2.5 mg, or cumulative monthly doses up to 8 times (rat) or 6 times (monkey) the recommended human once-monthly oral dose of 150 mg, based on body surface area (mg/m 2 ) or area under the curve (AUC) comparison. In monkeys, ibandronate maintained the positive correlation between bone mass and strength at the ulna and femoral neck. New bone formed in the presence of ibandronate had normal histologic structure and did not show mineralization defects.

Clinical studies
This field may contain references to clinical studies in place of detailed discussion in other sections of the labeling.14 CLINICAL STUDIES 14.1 Treatment of Postmenopausal Osteoporosis Daily Dosing The effectiveness and safety of ibandronate sodium tablets were demonstrated in a randomized, double-blind, placebo-controlled, multinational study (Treatment Study) of 2946 women aged 55 to 80 years, who were on average 21 years postmenopause, who had lumbar spine BMD 2 to 5 SD below the premenopausal mean (T-score) in at least one vertebra [L1 to L4], and who had 1 to 4 prevalent vertebral fractures. Ibandronate sodium tablets were evaluated at oral doses of 2.5 mg daily and 20 mg intermittently. The main outcome measure was the occurrence of new radiographically diagnosed vertebral fractures after 3 years of treatment. The diagnosis of an incident vertebral fracture was based on both qualitative diagnosis by the radiologist and quantitative morphometric criterion. The morphometric criterion required the dual occurrence of 2 events: a relative height ratio or relative height reduction in a vertebral body of at least 20%, together with at least a 4 mm absolute decrease in height. All women received 400 international units vitamin D and 500 mg calcium supplementation per day. Effect on Fracture Incidence Ibandronate sodium tablets 2.5 mg daily significantly reduced the incidence of new vertebral (primary efficacy measure) and of new and worsening vertebral fractures. Over the course of the 3-year study, the risk for vertebral fracture was 9.6% in the placebo-treated women and 4.7% in the women treated with ibandronate sodium tablets 2.5 mg (p<0.001) (see Table 3) . Table 3 Effect of Ibandronate Sodium Tablets on the Incidence of Vertebral Fracture in the 3-Year Osteoporosis Treatment Study* Proportion of Patients with Fracture (%) Placebo n=975 Ibandronate sodium tablets 2.5 mg Daily n=977 Absolute Risk Reduction (%) 95% CI Relative Risk Reduction (%) 95% CI New Vertebral Fracture 9.6 4.7 4.9 52** 0-3 Year (2.3, 7.4) (29, 68) New and Worsening Vertebral Fracture 10.4 5.1 5.3 52 0-3 Year (2.6, 7.9) (30, 67) Clinical (Symptomatic) Vertebral Fracture 5.3 2.8 2.5 49 0-3 Year (0.6, 4.5) (14, 69) * The endpoint value is the value at the study's last time point, 3 years, for all patients who had a fracture identified at that time; otherwise, the last postbaseline value prior to the study's last time point is used. ** p=0.0003 vs. placebo Ibandronate sodium tablets 2.5 mg daily did not reduce the incidence of nonvertebral fractures (secondary efficacy measure). There was a similar number of nonvertebral osteoporotic fractures at 3 years reported in women treated with ibandronate sodium tablets 2.5 mg daily [9.1%, (95% CI: 7.1%, 11.1%)] and placebo [8.2%, (95% CI: 6.3%, 10.2%)]. The two treatment groups were also similar with regard to the number of fractures reported at the individual nonvertebral sites: pelvis, femur, wrist, forearm, rib, and hip. Bone Mineral Density (BMD) Ibandronate sodium tablets significantly increased BMD at the lumbar spine and hip relative to treatment with placebo. In the 3-year osteoporosis treatment study, ibandronate sodium tablets 2.5 mg daily produced increases in lumbar spine BMD that were progressive over 3 years of treatment and were statistically significant relative to placebo at 6 months and at all later time points. Lumbar spine BMD increased by 6.4% after 3 years of treatment with 2.5 mg daily ibandronate sodium tablets compared with 1.4% in the placebo group. Table 4 displays the significant increases in BMD seen at the lumbar spine, total hip, femoral neck, and trochanter compared to placebo. Table 4 Mean Percent Change in BMD from Baseline to Endpoint in Patients Treated Daily with Ibandronate Sodium Tablets 2.5 mg or Placebo in the 3-Year Osteoporosis Treatment Study The endpoint value is the value at the study's last time point, 3 years, for all patients who had BMD measured at that time; otherwise, the last postbaseline value prior to the study's last time point is used. Placebo Ibandronate sodium tablets 2.5 mg Daily Lumbar Spine 1.4 (n=693) 6.4 (n=712) Total Hip -0.7 (n=638) 3.1 (n=654) Femoral Neck -0.7 (n=683) 2.6 (n=699) Trochanter 0.2 (n=683) 5.3 (n=699) Bone Histology The effects of ibandronate sodium tablets 2.5 mg daily on bone histology were evaluated in iliac crest biopsies from 16 women after 22 months of treatment and 20 women after 34 months of treatment. The histological analysis of bone biopsies showed bone of normal quality and no indication of osteomalacia or a mineralization defect. Once-Monthly Dosing The effectiveness and safety of ibandronate sodium tablets once-monthly were demonstrated in a randomized, double-blind, multinational, noninferiority trial in 1602 women aged 54 to 81 years, who were on average 18 years postmenopause, and had L2 to L4 lumbar spine BMD T-score below -2.5 SD at baseline. The main outcome measure was the comparison of the percentage change from baseline in lumbar spine BMD after 1 year of treatment with once-monthly ibandronate (100 mg, 150 mg) to daily ibandronate (2.5 mg). All patients received 400 international units vitamin D and 500 mg calcium supplementation per day. Ibandronate sodium tablets 150 mg once-monthly (n=327) was shown to be noninferior to ibandronate sodium tablets 2.5 mg daily (n=318) in lumbar spine BMD in a 1-year, double-blind, multicenter study of women with postmenopausal osteoporosis. In the primary efficacy analysis (per-protocol population), the mean increases from baseline in lumbar spine BMD at 1 year were 3.86% (95% CI: 3.40%, 4.32%) in the 2.5 mg daily group and 4.85% (95% CI: 4.41%, 5.29%) in the 150 mg once-monthly group; the mean difference between 2.5 mg daily and 150 mg once-monthly was 0.99% (95% CI: 0.38%, 1.60%), which was statistically significant (p=0.002). The results of the intent-to-treat analysis were consistent with the primary efficacy analysis. The 150 mg once-monthly group also had consistently higher BMD increases at the other skeletal sites compared to the 2.5 mg daily group. 14.2 Prevention of Postmenopausal Osteoporosis Daily Dosing The safety and effectiveness of ibandronate sodium tablets 2.5 mg 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 tablets at three dose levels (0.5 mg, 1.0 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 tablets 2.5 mg 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 tablets 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 tablets 2.5 mg daily increased BMD of the total hip by 1.8%, the femoral neck by 2.0%, and the trochanter by 2.1%. Once-Monthly Dosing The safety and effectiveness of ibandronate sodium tablets 150 mg 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 tablets 150 mg 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 tablets and placebo treatment groups, respectively. BMD at other skeletal sites was also increased relative to baseline values.

Geriatric use
Information about any limitations on any geriatric indications, needs for specific monitoring, hazards associated with use of the drug in the geriatric population.8.5 Geriatric Use Of the patients receiving ibandronate sodium tablets 2.5 mg daily in postmenopausal osteoporosis studies, 52% were over 65 years of age, and 10% were over 75 years of age. Of the patients receiving ibandronate sodium tablets 150 mg once-monthly in the postmenopausal osteoporosis 1-year study, 52% were over 65 years of age, and 9% were over 75 years of age. No overall differences in effectiveness or safety were observed between these patients and younger patients but greater sensitivity in some older individuals cannot be ruled out.
Nursing mothers
Information about excretion of the drug in human milk and effects on the nursing infant, including pertinent adverse effects observed in animal offspring.8.2 Lactation Risk Summary Ibandronate sodium tablets 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.
Pediatric use
Information about any limitations on any pediatric indications, needs for specific monitoring, hazards associated with use of the drug in any subsets of the pediatric population (such as neonates, infants, children, or adolescents), differences between pediatric and adult responses to the drug, and other information related to the safe and effective pediatric use of the drug.8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established.
Pregnancy
Information about effects the drug may have on pregnant women or on a fetus. This field may be ommitted if the drug is not absorbed systemically and the drug is not known to have a potential for indirect harm to the fetus. It may contain information about the established pregnancy category classification for the drug. (That information is nominally listed in the teratogenic_effects field, but may be listed here instead.)8.1 Pregnancy Risk Summary Ibandronate sodium tablets is not indicated for use in women of reproductive potential. There are no data with ibandronate sodium use in pregnant women to inform any drug-associated risks. In reproductive toxicity studies in the rat, ibandronate sodium 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, ibandronate sodium 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 ( see Data ). 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.
Use in specific populations
Information about use of the drug by patients in specific populations, including pregnant women and nursing mothers, pediatric patients, and geriatric patients.8 USE IN SPECIFIC POPULATIONS Ibandronate sodium tablets are not recommended in patients with severe renal impairment (creatinine clearance less than 30 mL/min). ( 5.6 , 8.6 ) 8.1 Pregnancy Risk Summary Ibandronate sodium tablets is not indicated for use in women of reproductive potential.

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. 8.2 Lactation Risk Summary Ibandronate sodium tablets 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. 8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established. 8.5 Geriatric Use Of the patients receiving ibandronate sodium tablets 2.5 mg daily in postmenopausal osteoporosis studies, 52% were over 65 years of age, and 10% were over 75 years of age. Of the patients receiving ibandronate sodium tablets 150 mg once-monthly in the postmenopausal osteoporosis 1-year study, 52% were over 65 years of age, and 9% were over 75 years of age. No overall differences in effectiveness or safety were observed between these patients and younger patients but greater sensitivity in some older individuals cannot be ruled out. 8.6 Renal Impairment Ibandronate sodium tablets are not recommended for use in patients with severe renal impairment (creatinine clearance less than 30 mL/min).
