What Is Denosumab-Bmwo Used For?

1 INDICATIONS AND USAGE Stoboclo is a RANK ligand (RANKL) inhibitor indicated for treatment: of postmenopausal women with osteoporosis at high risk for fracture ( 1.1 ) to increase bone mass in men with osteoporosis at high risk for fracture ( 1.2 ) of glucocorticoid-induced osteoporosis in men and women at high risk for fracture ( 1.3 ) to increase bone mass in men at high risk for fracture receiving androgen deprivation therapy for nonmetastatic prostate cancer ( 1.4 ) to increase bone mass in women at high risk for fracture receiving adjuvant aromatase inhibitor therapy for breast cancer ( 1.5 ) 1.1 Treatment of Postmenopausal Women with Osteoporosis at High Risk for Fracture Stoboclo is indicated for the treatment of postmenopausal women with osteoporosis at high risk for fracture, defined as a history of osteoporotic fracture, or multiple risk factors for fracture; or patients who have failed or are intolerant to other available osteoporosis therapy. In postmenopausal women with osteoporosis, denosumab reduces the incidence of vertebral, nonvertebral, and hip fractures [see Clinical Studies (14.1) ] . 1.2 Treatment to Increase Bone Mass in Men with Osteoporosis Stoboclo is indicated for treatment to increase bone mass in men with osteoporosis at high risk for fracture, defined as a history of osteoporotic fracture, or multiple risk factors for fracture; or patients who have failed or are intolerant to other available osteoporosis therapy [see Clinical Studies (14.2) ] . 1.3 Treatment of Glucocorticoid-Induced Osteoporosis Stoboclo is indicated for the treatment of glucocorticoid-induced osteoporosis in men and women at high risk of fracture who are either initiating or continuing systemic glucocorticoids in a daily dosage equivalent to 7.5 mg or greater of prednisone and expected to remain on glucocorticoids for at least 6 months. High risk of fracture is defined as a history of osteoporotic fracture, multiple risk factors for fracture, or patients who have failed or are intolerant to other available osteoporosis therapy [see Clinical Studies (14.3) ] . 1.4 Treatment of Bone Loss in Men Receiving Androgen Deprivation Therapy for Prostate Cancer Stoboclo is indicated as a treatment to increase bone mass in men at high risk for fracture receiving androgen deprivation therapy (ADT) for nonmetastatic prostate cancer. In these patients denosumab also reduced the incidence of vertebral fractures [see Clinical Studies (14.4) ] . 1.5 Treatment of Bone Loss in Women Receiving Adjuvant Aromatase Inhibitor Therapy for Breast Cancer Stoboclo is indicated as a treatment to increase bone mass in women at high risk for fracture receiving adjuvant aromatase inhibitor therapy for breast cancer [see Clinical Studies (14.5) ] .

Dosage and Administration

2 DOSAGE AND ADMINISTRATION Pregnancy must be ruled out prior to administration of Stoboclo. ( 2.1 ) Before initiating Stoboclo in patients with advanced chronic kidney disease, including dialysis patients, evaluate for the presence of chronic kidney disease mineral and bone disorder with intact parathyroid hormone, serum calcium, 25(OH) vitamin D, and 1,25(OH) 2 vitamin D. ( 2.2 , 5.1 , 8.6 ) Stoboclo should be administered by a healthcare provider. ( 2.3 ) Administer 60 mg every 6 months as a subcutaneous injection in the upper arm, upper thigh, or abdomen. ( 2.3 ) Instruct patients to take calcium 1000 mg daily and at least 400 IU vitamin D daily. ( 2.3 ) 2.1 Pregnancy Testing Prior to Initiation of Stoboclo Pregnancy must be ruled out prior to administration of Stoboclo. Perform pregnancy testing in all females of reproductive potential prior to administration of Stoboclo. Based on findings in animals, denosumab products can cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1 , 8.3 )] . 2.2 Laboratory Testing in Patients with Advanced Chronic Kidney Disease Prior to Initiation of Stoboclo In patients with advanced chronic kidney disease [i.e., estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m 2 ], including dialysis-dependent patients, evaluate for the presence of chronic kidney disease mineral and bone disorder (CKD-MBD) with intact parathyroid hormone (iPTH), serum calcium, 25(OH) vitamin D, and 1,25 (OH) 2 vitamin D prior to decisions regarding Stoboclo treatment. Consider also assessing bone turnover status (serum markers of bone turnover or bone biopsy) to evaluate the underlying bone disease that may be present [see Warnings and Precautions (5.1) ] . 2.3 Recommended Dosage Stoboclo should be administered by a healthcare provider. The recommended dose of Stoboclo is 60 mg administered as a single subcutaneous injection once every 6 months. Administer Stoboclo via subcutaneous injection in the upper arm, the upper thigh, or the abdomen. All patients should receive calcium 1000 mg daily and at least 400 IU vitamin D daily [see Warnings and Precautions (5.1) ] . If a dose of Stoboclo is missed, administer the injection as soon as the patient is available. Thereafter, schedule injections every 6 months from the date of the last injection. 2.4 Preparation and Administration Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Stoboclo is a clear, colorless to pale yellow solution. Do not use if the solution is discolored or cloudy or if the solution contains particles or foreign particulate matter. Prior to administration, Stoboclo may be removed from the refrigerator and brought to room temperature up to 25°C (77°F) by standing in the original carton. This generally takes 15 to 30 minutes. Do not warm Stoboclo in any other way [see How Supplied/Storage and Handling (16) ] ....

Treatment of Postmenopausal Women with Osteoporosis The safety of denosumab in the treatment of postmenopausal osteoporosis was assessed in a 3-year, randomized, double-blind, placebo-controlled, multinational study of 7808 postmenopausal women aged 60 to 91 years. A total of 3876 women were exposed to placebo and 3886 women were exposed to denosumab administered subcutaneously once every 6 months as a single 60 mg dose. All women were instructed to take at least 1000 mg of calcium and 400 IU of vitamin D supplementation per day. The incidence of all-cause mortality was 2.3% (n = 90) in the placebo group and 1.8% (n = 70) in the denosumab group. The incidence of nonfatal serious adverse events was 24.2% in the placebo group and 25.0% in the denosumab group. The percentage of patients who withdrew from the study due to adverse events was 2.1% and 2.4% for the placebo and denosumab groups, respectively. The most common adverse reactions reported with denosumab in patients with postmenopausal osteoporosis are back pain, pain in extremity,...

4 CONTRAINDICATIONS Stoboclo is contraindicated in: Patients with hypocalcemia: Pre-existing hypocalcemia must be corrected prior to initiating therapy with Stoboclo [see Warnings and Precautions (5.1) ] . Pregnant women: Denosumab products may cause fetal harm when administered to a pregnant woman. In women of reproductive potential, pregnancy testing should be performed prior to initiating treatment with Stoboclo [see Use in Specific Populations (8.1) ] . Patients with hypersensitivity to denosumab products: Stoboclo is contraindicated in patients with a history of systemic hypersensitivity to any component of the product. Reactions have included anaphylaxis, facial swelling, and urticaria [see Warnings and Precautions (5.3) , Adverse Reactions (6.2) ] . Hypocalcemia ( 4 , 5.1 ) Pregnancy ( 4 , 8.1 ) Known hypersensitivity to denosumab products ( 4 , 5.3 )

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary Stoboclo is contraindicated for use in pregnant women because it may cause harm to a fetus. There are insufficient data with denosumab products use in pregnant women to inform any drug-associated risks for adverse developmental outcomes. In utero denosumab exposure from cynomolgus monkeys dosed monthly with denosumab throughout pregnancy at a dose 50-fold higher than the recommended human dose based on body weight resulted in increased fetal loss, stillbirths, and postnatal mortality, and absent lymph nodes, abnormal bone growth, and decreased neonatal growth [see Data ] . Data Animal Data The effects of denosumab on prenatal development have been studied in both cynomolgus monkeys and genetically engineered mice in which RANK ligand (RANKL) expression was turned off by gene removal (a "knockout mouse"). In cynomolgus monkeys dosed subcutaneously with denosumab throughout pregnancy starting at gestational day 20 and at a pharmacologically active dose 50-fold higher than the recommended human dose based on body weight, there was increased fetal loss during gestation, stillbirths, and postnatal mortality. Other findings in offspring included absence of axillary, inguinal, mandibular, and mesenteric lymph nodes; abnormal bone growth, reduced bone strength, reduced hematopoiesis, dental dysplasia, and tooth malalignment; and decreased neonatal growth. At birth out to 1 month of age, infants had measurable blood levels of denosumab (22-621% of maternal levels). Following a recovery period from birth out to 6 months of age, the effects on bone quality and strength returned to normal; there were no adverse effects on tooth eruption, though dental dysplasia was still apparent; axillary and inguinal lymph nodes remained absent, while mandibular and mesenteric lymph nodes were present, though small; and minimal to moderate mineralization in multiple tissues was seen in one recovery animal. There was no evidence of maternal harm prior to labor;...
