4 Contraindications

Additions and/or revisions underlined:

Jubbonti is contraindicated in:

      • Patients with hypocalcemia: Pre-existing hypocalcemia must be corrected prior to initiating therapy with Jubbonti [see Warnings and Precautions (5.1)].

      • Pregnant women: Denosumab products 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 Jubbonti [see Use in Specific Populations (8.1)].

      • Patients with hypersensitivity to denosumab products: Jubbonti 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), Adverse Reactions (6.2)].

6 Adverse Reactions

6.1 Clinical Trials Experience

Additions and/or revisions underlined:

The incidence of all-cause mortality was 2.3% (n = 90) in the placebo group and 1.8% (n = 70) in the denosumab group. The incidence of nonfatal serious adverse events was 24.2% in the placebo group and 25.0% in the denosumab group. The percentage of patients who withdrew from the study due to adverse events was 2.1% and 2.4% for the placebo and denosumab groups, respectively. The most common adverse reactions reported with denosumab in patients with postmenopausal osteoporosis are back pain, pain in extremity, musculoskeletal pain, hypercholesterolemia, and cystitis.

8 Use in Specific Populations

8.4 Pediatric Use

Additions and/or revisions underlined:

The safety and effectiveness of Jubbonti have not been established in pediatric patients.

In one multicenter, open-label study with denosumab conducted in 153 pediatric patients with osteogenesis imperfecta, aged 2 to 17 years, evaluating fracture risk reduction, efficacy was not established.

Hypercalcemia has been reported in pediatric patients with osteogenesis imperfecta treated with denosumab products. Some cases required hospitalization and were complicated by acute renal injury [see Warnings and Precautions (5.11)]. Clinical studies in pediatric patients with osteogenesis imperfecta were terminated early due to the occurrence of life-threatening events and hospitalizations due to hypercalcemia.

Based on results from animal studies, denosumab may negatively affect long-bone growth and dentition in pediatric patients below the age of 4 years.
