Osteonecrosis of the Jaw (ONJ)

In the primary treatment phases of Studies 20050136, 20050244, and 20050103, ONJ was confirmed in 1.8% of patients in the denosumab group (median exposure of 12.0 months; range: 0.1-41) and 1.3% of patients in the zoledronic acid group. The trials in patients with breast (Study 20050136) or prostate (Study 20050103) cancer included an open-label extension treatment phase where patients were offered denosumab 120 mg once every 4 weeks (median overall exposure of 14.9 months; range: 0.1-67.2). The patient-year adjusted incidence (number of events per 100 patient years) of confirmed ONJ was 1.1% during the first year of treatment, 3.7% in the second year, and 4.6% per year thereafter. The median time to ONJ was 20.6 months (range: 4-53) [see Warnings and Precautions (5.4)].

Osteonecrosis of the Jaw (ONJ)

In the pooled analysis of Study 20062004 and Study 20040215, ONJ was confirmed in 7% of patients who received denosumab (median number of doses received: 33; range: 4-138 doses).

Study 20140114 (NCT03301857) was a 5-year long term follow-up study for patients (n = 85) who completed Study 20062004. In Study 20062004 and Study 20140114 combined, ONJ was confirmed in 7% of patients who received denosumab (median time on trial 62.2 months (range 0 - 173). The combined patient-year adjusted incidence (number of events per 100 patient years) of confirmed ONJ was 0.2% during the first year of treatment, 1.5% in the second year, 1.8% in the third year, 2.1% in the fourth year, 1.4% in the fifth year, and 1.5% thereafter [see Warnings and Precautions (5.4)].

Atypical Subtrochanteric and Diaphyseal Fracture

In the pooled analysis of Study 20062004 and Study 20040215, atypical femoral fracture was observed in 0.9% of patients who received denosumab (median number of doses received: 33; range: 4-138 doses).

In Study 20062004 and Study 20140114, the combined incidence of confirmed atypical femoral fracture was 1.3% of patients who received denosumab [see Warnings and Precautions (5.5)].
