Boxed Warning
Patients with advanced chronic kidney disease (eGFR < 30 mL/min/1.73 m2), including dialysis-dependent patients, are at greater risk of severe hypocalcemia following Prolia administration. Severe hypocalcemia resulting in hospitalization, life-threatening events and fatal cases have been reported [see Warnings and Precautions (5.1)]. The presence of chronic kidney disease-mineral bone disorder (CKD-MBD) markedly increases the risk of hypocalcemia in these patients [see Warnings and Precautions (5.1)]. Prior to initiating Prolia in patients with advanced chronic kidney disease, evaluate for the presence of CKD-MBD. Treatment with Prolia in these patients should be supervised by a healthcare provider with expertise in the diagnosis and management of CKD-MBD [see Dosage and Administration (2.2) and Warnings and Precautions (5.1)].
Contraindications
Prolia is contraindicated in: Patients with hypocalcemia: Pre-existing hypocalcemia must be corrected prior to initiating therapy with Prolia [see Warnings and Precautions (5.1)]. Pregnant women: Prolia 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 Prolia [see Use in Specific Populations (8.1)]. Patients with hypersensitivity to Prolia: Prolia 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) and Adverse Reactions (6.2)].
Adverse Reactions
The following serious adverse reactions are discussed below and also elsewhere in the labeling: Severe Hypocalcemia and Mineral Metabolism Changes [see Warnings and Precautions (5.1)] Hypersensitivity [see Warnings and Precautions (5.3)] Osteonecrosis of the Jaw [see Warnings and Precautions (5.4)] Atypical Subtrochanteric and Diaphyseal Femoral Fractures [see Warnings and Precautions (5.5)] Multiple Vertebral Fractures (MVF) Following Discontinuation of Prolia Treatment [see Warnings and Precautions (5.6)] Serious Infections [see Warnings and Precautions (5.7)] Dermatologic Adverse Reactions [see Warnings and Precautions (5.8)] The most common adverse reactions reported with Prolia in patients with postmenopausal osteoporosis are back pain, pain in extremity, musculoskeletal pain, hypercholesterolemia, and cystitis. The most common adverse reactions reported with Prolia in men with osteoporosis are back pain, arthralgia, and nasopharyngitis. The most common adverse reactions reported with Prolia in patients with glucocorticoid-induced osteoporosis are back pain, hypertension, bronchitis, and headache. The most common (per patient incidence ≥ 10%) adverse reactions reported with Prolia in patients with bone loss receiving androgen deprivation therapy for prostate cancer or adjuvant aromatase inhibitor therapy for breast cancer are arthralgia and back pain. Pain in extremity and musculoskeletal pain have also been reported in clinical trials. The most common adverse reactions leading to discontinuation of Prolia in patients with postmenopausal osteoporosis are back pain and constipation.
Mechanism of Action
Prolia binds to RANKL, a transmembrane or soluble protein essential for the formation, function, and survival of osteoclasts, the cells responsible for bone resorption. Prolia prevents RANKL from activating its receptor, RANK, on the surface of osteoclasts and their precursors. Prevention of the RANKL/RANK interaction inhibits osteoclast formation, function, and survival, thereby decreasing bone resorption and increasing bone mass and strength in both cortical and trabecular bone.
