Basel, March 5, 2024 -- Sandoz, the global leader in generic and biosimilar medicines, today announced that the US Food and Drug Administration (FDA) approved Wyost (denosumab-bbdz), an interchangeable biosimilar to Xgeva.

The FDA also approved Jubbonti (denosumab-bbdz), an interchangeable biosimilar to Prolia. Wyost and Jubbonti are the first and only FDA-approved denosumab biosimilars, used to treat all indications of the reference medicines.

Keren Haruvi, President Sandoz North America, said: "Sandoz has achieved the first FDA approval for biosimilars to denosumab, a medicine that can address primary and secondary bone loss, such as osteoporosis, as well as cancer-related skeletal events, which are disease states that can profoundly reduce quality of life for patients. I am proud that Sandoz continues to pioneer access to these life-changing medicines for the patients who need them most."

Wyost is approved to prevent skeletal-related events (SREs) in patients with multiple myeloma and in patients with bone metastases from solid tumors, to treat 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, and to treat hypercalcemia of malignancy refractory to bisphosphonate therapy.1

Bone is the third most frequent site for metastatic tumors.2 Nearly all types of cancer can spread to the bone and cause pain and fractures, though cancers that often metastasize in bones include breast and prostate.3

Jubbonti is approved to treat postmenopausal women with osteoporosis at high risk for fracture, to increase bone mass in men with osteoporosis at high risk for fracture, to treat glucocorticoid-induced osteoporosis in men and women at high risk for fracture, to increase bone mass in men at high risk for fracture receiving androgen deprivation therapy for nonmetastatic prostate cancer, and to increase bone mass in women at high risk for fracture receiving adjuvant aromatase inhibitor therapy for breast cancer.4

Osteoporosis is a bone disease that develops when bone mineral density and bone mass decrease or when bone strength and structure change. People living with osteoporosis typically do not have symptoms and might not know they have the disease until they experience a fracture. More than 10 million US adults aged 50 and over live with osteoporosis, a major cause of fractures in postmenopausal women and in older men.5,6 Half of all women over the age of 50 will experience an osteoporotic fracture during their lifetime.7

The FDA approval is based on robust clinical studies and accompanied by labeling with safety warnings. The Jubbonti approval is also accompanied by approval of Sandoz’s Jubbonti Risk Evaluation and Mitigation Strategy (REMS) program, which is designed to inform prescribers and patients about the risk of severe hypocalcemia associated with Jubbonti in patients with advanced chronic kidney disease, including dialysis-dependent patients.

Wyost and Jubbonti have the same dosage form, route of administration, dosing regimen and presentation as the respective reference medicines. Wyost and Jubbonti are approved as interchangeable with the reference medicines for all indications.

Given ongoing patent litigation around these products, Sandoz will not comment on anticipated launch timing or other launch details at this time.

 About Wyost® (denosumab-bbdz) 

Wyost 120 mg/1.7 mL (70 mg/mL) injection has been approved by the FDA as interchangeable with the reference medicine, a human monoclonal antibody designed to bind to the RANKL protein, an activator of osteoclasts (cells involved in breaking down bone tissue).8,9 Wyost is indicated in the US to prevent SREs in patients with multiple myeloma and in patients with bone metastases from solid tumors, to treat 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, and to treat hypercalcemia of malignancy refractory to bisphosphonate therapy.1

SELECT IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS

Hypocalcemia and known clinically significant hypersensitivity to denosumab products.

WARNINGS AND PRECAUTIONS

Same Active Ingredient: Patients receiving Wyost should not receive other denosumab products concomitantly. Hypersensitivity reactions including anaphylaxis may occur. Discontinue permanently if a clinically significant reaction occurs. Hypocalcemia: Denosumab products can cause severe symptomatic hypocalcemia. Fatal cases have been reported with denosumab products use. Correct hypocalcemia prior to initiating Wyost. Monitor calcium levels during therapy, especially in the first weeks of initiating therapy, and adequately supplement all patients with calcium and vitamin D. Osteonecrosis of the jaw (ONJ) has been reported in patients receiving denosumab products. Perform an oral examination prior to starting Wyost. Monitor for symptoms. Avoid invasive dental procedures during treatment with Wyost. Atypical femoral fracture: Evaluate patients with thigh or groin pain to rule out a femoral fracture. Hypercalcemia Following Treatment Discontinuation in Patients with Giant Cell Tumor of Bone and in Patients with Growing Skeletons: Monitor patients for signs and symptoms of hypercalcemia, and manage as clinically appropriate. Multiple Vertebral Fractures (MVF) Following Treatment Discontinuation: When Wyost treatment is discontinued, evaluate the individual patient’s risk for vertebral fractures. Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of potential risk to the fetus and to use effective contraception.

ADVERSE REACTIONS

Bone Metastasis from Solid Tumors: Most common adverse reactions (≥ 25%) were fatigue/asthenia, hypophosphatemia, and nausea. Multiple Myeloma: Most common adverse reactions (≥ 10%) were diarrhea, nausea, anemia, back pain, thrombocytopenia, peripheral edema, hypocalcemia, upper respiratory tract infection, rash, and headache. Giant Cell Tumor of Bone: Most common adverse reactions (≥ 10%) were arthralgia, headache, nausea, back pain, fatigue, and pain in extremity. Hypercalcemia of Malignancy: Most common adverse reactions (> 20%) were nausea, dyspnea, decreased appetite, headache, peripheral edema, vomiting, anemia, constipation, and diarrhea.

USE IN SPECIFIC POPULATIONS

Pediatric patients: Recommended only for treatment of skeletally mature adolescents with giant cell tumor of bone. Renal impairment: Patients with creatinine clearance less than 30 mL/min or receiving dialysis are at risk for hypocalcemia. Adequately supplement with calcium and vitamin D.
