CELLTRION® CONNECTA patient support program that provides personalized support to you and your patients prescribed OSENVELT®

IMPORTANT SAFETY INFORMATION

Contraindications: Patients with hypocalcemia or with known clinically significant hypersensitivity to denosumab products.

Drug Products with Same Active Ingredient. Patients receiving OSENVELT should not receive other denosumab products concomitantly.

Hypersensitivity. Clinically significant hypersensitivity including anaphylaxis has been reported with denosumab products. If an anaphylactic or other clinically significant allergic reaction occurs, initiate appropriate therapy and discontinue further use of OSENVELT.

Hypocalcemia. Severe hypocalcemia can occur, and fatal cases have been reported. Monitor calcium levels and calcium and vitamin D intake.

Osteonecrosis of the Jaw (ONJ). ONJ can occur in patients on OSENVELT. A routine oral exam and appropriate preventive dentistry are recommended before starting and during treatment with OSENVELT. Good oral hygiene should be maintained. Avoid invasive dental procedures during treatment with OSENVELT. For invasive dental procedures, consider temporary discontinuation of OSENVELT. If ONJ develops, consult a dentist or oral surgeon, as extensive surgery may worsen ONJ; consider discontinuing OSENVELT based on benefit-risk assessment.

Atypical Subtrochanteric and Diaphyseal Femoral Fracture. Atypical femoral fracture has been reported with denosumab products. During OSENVELT treatment, patients should be advised to report new or unusual thigh, hip, or groin pain. Patients with thigh or groin pain should be evaluated for an atypical femur fracture, including assessment for potential fractures in the contralateral limb. Interruption of OSENVELT therapy should be considered, pending a benefit-risk assessment, on an individual basis.

Hypercalcemia Following Treatment Discontinuation in Patients with Giant Cell Tumor of Bone and in Patients with Growing Skeletons. Clinically significant hypercalcemia, sometimes requiring hospitalization and complicated by acute renal injury, has occurred in denosumab-treated patients with giant cell tumor of bone and in those with growing skeletons, often within the first year after discontinuation. After treatment discontinuation, monitor for hypercalcemia symptoms, check serum calcium periodically, reassess calcium and vitamin D needs, and manage as appropriate.

Multiple Vertebral Fractures (MVF) Following Treatment Discontinuation. Following discontinuation of denosumab treatment, fracture risk increases, including the risk of multiple vertebral fractures. Evaluate the individual patient’s risk for vertebral fractures after OSENVELT discontinuation.

Embryo-Fetal Toxicity. Denosumab may cause fetal harm based on animal studies and its mechanism of action. Verify pregnancy status in females of reproductive potential before starting OSENVELT, and advise them to use effective contraception during treatment and for 5 months after the last dose to prevent fetal harm.
