Indications
- osteoporosis
- elderly women
- hypogonadism
- men on anti-androgen therapy (GnRH analog)
- effective in patients with renal impairment[10]
- modest efficacy[18]#
- prevention of cancer-related bone injury
- hypercalcemia of malignancy[15][16]*
- reduces risk of type 2 diabetes, foot ulcers & mortalty vs alendronate[28]
* not indicated for treatment of hypercalcemia of malignancy (GRS9)[7]
# disproportionate adverse effects including back pain & serious infections[18] (on list of medications to avoid)
Contraindications
- prevention of cancer-related bone injury from bone metastases due to prostate cancer (NGC)
Dosage
- 60 mg, 1-3 doses SQ every 3-6 months
- recommended injection sites include upper arm, upper thigh, or abdomen
- duration of therapy
- bone resorption transiently increases dramatically upon cessation of therapy, increasing risk of vertebral fractures[2][22][24]
- no established duration of therapy[19]
- duration of therapy 5 years[20]
- safe for 10 years of therapy[23]
- continued increases in bone mineral density without plateau
- if discontinued, use bisphosphonate to reduce osteoclastic activity & bone resorption[19]
- sequential therapy with zoledronate does not fully prevent a decrease in lumbar spine done mineral density after denosumab discontinuation[29]
prefilled syringe: 1 mL 60 mg/mL (single use)
vial: 1 mL 60 mg/mL (single use)
* No dosage adjustment with renal failure
Monitor
- serum calcium in patients on hemodialysis
Adverse effects
- back pain
- musculoskeletal pain,
- pain in the extremities
- hyperlipidemia
- cystitis
- osteonecrosis of the jaw[11]
- pancreatitis has been reported in clinical trials
- possible excess risk for cellulitis[12]
- hypocalcemia in hemodialysis patients[25][30]
- increased risk of severe hypocalcemia in patients with advanced chronic kidney disease[27][30]
- patients on dialysis or with mineral & bone disorder at highest risk
Drug interactions
- may not increase risk of infection with used in combination with biological response modifier[12]
Mechanism of action
- antibody to RANKL
- reduces osteoclasts & bone resorption
- may have beneficial effects on glycemic control[26]
Notes
- cost 2010: $825 per injection
- cost of $46,000 per vertebral fracture prevented[21]
- insurance approval generally requires renal failure (creatinine clearance < 30 mL/min)[7]
