Though covered by Medicare, the cost of XGEVA (denosumab) may represent a barrier to care or influence treatment decisions.10-12 As of 2025, BILPREVDA is ~51% less expensive than XGEVA.* Referenced prices are derived from published price lists and do not necessarily reflect actual prices paid by consumers or dispensers. Lower acquisition costs alone do not necessarily reflect a cost advantage in the outcome of the condition treated because there are other variables that affect relative costs.
*Based on comparison of wholesale acquisition cost (WAC) per dose. WAC prices: BILPREVDA $1,688.00 per dose; XGEVA $3,449.74 per dose. (Source: Medi-Span® Price Rx® as of Sept 2025).

PD, pharmacodynamics; PK, pharmacokinetics.
A 2-part pharmacokinetic similarity study of BILPREVDA (HLX14) and reference denosumab demonstrated biosimilarity in PK, PD, safety, and immunogenicity endpoints.
A randomized, double-blind, parallel-controlled, multicenter comparative clinical study in postmenopausal women with osteoporosis at high risk for fracture compared BILPREVDA (HLX14) to reference denosumab and evaluated efficacy, PD, PK, safety, and immunogenicity.

BILPREVDA is indicated for the prevention of skeletal-related events in patients with multiple myeloma and in patients with bone metastases from solid tumors.
BILPREVDA is indicated for the treatment of adults and skeletally mature adolescents with giant cell tumor of bone that is unresectable or where surgical resection is likely to result in severe morbidity.
BILPREVDA is indicated for the treatment of hypercalcemia of malignancy refractory to bisphosphonate therapy.
Pre-existing hypocalcemia must be corrected prior to initiating therapy with BILPREVDA. BILPREVDA is contraindicated in patients with known clinically significant hypersensitivity to denosumab products.
Patients receiving BILPREVDA should not receive other denosumab products concomitantly.
Denosumab products can cause severe symptomatic hypocalcemia, and fatal cases have been reported. Pre-existing hypocalcemia must be corrected prior to initiating BILPREVDA. Monitor calcium levels throughout therapy, especially in the first weeks of initiating therapy, and administer calcium, magnesium, and vitamin D as necessary. Concomitant use of calcimimetics and other drugs that can lower calcium levels may worsen hypocalcemia risk, and serum calcium should be closely monitored. Advise patients to contact a health care provider for symptoms of hypocalcemia.
An increased risk of hypocalcemia has been observed in clinical trials of patients with increasing renal dysfunction, most commonly with severe dysfunction (creatinine clearance less than 30 mL/min and/or on dialysis), and with inadequate/no calcium supplementation. Monitor calcium levels and calcium and vitamin D intake.
BILPREVDA is contraindicated in patients with known clinically significant hypersensitivity to denosumab products, including anaphylaxis. Reactions may include hypotension, dyspnea, upper airway edema, lip swelling, rash, pruritus, and urticaria. If an anaphylactic or other clinically significant allergic reaction occurs, initiate appropriate therapy and discontinue BILPREVDA therapy permanently.
ONJ has been reported in patients receiving denosumab products, manifesting as jaw pain, osteomyelitis, osteitis, bone erosion, tooth or periodontal infection, toothache, gingival ulceration, or gingival erosion. Persistent pain or slow healing of the mouth or jaw after dental surgery may also be manifestations of ONJ. In clinical trials in patients with cancer, the incidence of ONJ was higher with longer duration of exposure.
A history of tooth extraction, poor oral hygiene, or use of a dental appliance may be predisposing factors to developing ONJ. Other risk factors for the development of ONJ include immunosuppressive therapy, treatment with angiogenesis inhibitors, systemic corticosteroids, diabetes, and gingival infections.
Perform an oral examination and appropriate preventive dentistry prior to the initiation of BILPREVDA and periodically during therapy. Advise patients regarding oral hygiene practices. Avoid invasive dental procedures during treatment with BILPREVDA. Consider temporarily interrupting therapy if an invasive dental procedure must be performed.
Patients who are suspected of having or who develop ONJ while on BILPREVDA should receive care by a dentist or an oral surgeon. In these patients, extensive dental surgery to treat ONJ may exacerbate the condition.
Atypical femoral fracture has been reported with denosumab products. These fractures can occur anywhere in the femoral shaft from just below the lesser trochanter to above the supracondylar flare and are transverse or short oblique in orientation without evidence of comminution.
Atypical femoral fractures most commonly occur with minimal or no trauma to the affected area. They may be bilateral and many patients report prodromal pain in the affected area, usually presenting as dull, aching thigh pain, weeks to months before a complete fracture occurs. A number of reports note that patients were also receiving treatment with glucocorticoids (eg, prednisone) at the time of fracture. During BILPREVDA treatment, patients should be advised to report new or unusual thigh, hip, or groin pain. Any patient who presents with thigh or groin pain should be suspected of having an atypical fracture and should be evaluated to rule out an incomplete femur fracture. Patients presenting with an atypical femur fracture should also be assessed for symptoms and signs of fracture in the contralateral limb. Interruption of BILPREVDA therapy should be considered, pending a risk/benefit assessment, on an individual basis.
Clinically significant hypercalcemia requiring hospitalization and complicated by acute renal injury has been reported in denosumab-treated patients with GCTB and in patients with growing skeletons. Hypercalcemia has been reported within the first year after treatment discontinuation. After treatment is discontinued, monitor patients for signs and symptoms of hypercalcemia, assess serum calcium periodically, reevaluate the patients’ calcium and vitamin D supplementation, and treat appropriately.
MVF have been reported following discontinuation of treatment with denosumab products. Patients at higher risk for MVF include those with risk factors for or a history of osteoporosis or prior fractures. When BILPREVDA treatment is discontinued, evaluate the individual patient’s risk for vertebral fractures.
Based on data from animal studies and its mechanism of actions, denosumab products can cause fetal harm when administered to a pregnant woman.
Verify the pregnancy status of females of reproductive potential prior to the initiation of BILPREVDA. Advise females of reproductive potential to use effective contraception during therapy, and for at least 5 months after the last dose of BILPREVDA. Advise pregnant women and females of reproductive potential that exposure to BILPREVDA during pregnancy or within 5 months prior to conception can result in fetal harm.
The most common adverse reactions (incidence ≥25%) in patients with bone metastasis from solid tumors were fatigue/asthenia, hypophosphatemia, and nausea. The most common serious adverse reaction was dyspnea. The most common adverse reactions resulting in discontinuation were osteonecrosis and hypocalcemia.
The most common adverse reactions (incidence ≥10%) in patients with multiple myeloma were diarrhea, nausea, anemia, back pain, thrombocytopenia, peripheral edema, hypocalcemia, upper respiratory tract infection, rash, and headache. The most common serious adverse reaction was pneumonia. The most common adverse reaction resulting in discontinuation was osteonecrosis of the jaw.
The most common adverse reactions (incidence ≥10%) in patients with GCTB were arthralgia, back pain, pain in extremity, fatigue, headache, nausea, nasopharyngitis, musculoskeletal pain, toothache, vomiting, hypophosphatemia, constipation, diarrhea, and cough. The most frequent serious adverse reactions were osteonecrosis of the jaw, bone giant cell tumor, anemia, pneumonia, and back pain. The most common adverse reaction resulting in discontinuation was osteonecrosis of the jaw.
The most common adverse reactions (incidence >20%) in patients with hypercalcemia of malignancy were nausea, dyspnea, decreased appetite, headache, peripheral edema, vomiting, anemia, constipation, and diarrhea.
