Denosumab for Prolonging Bone Metastasis-Free Survival in Men With Hormone-Refractory Prostate Cancer

Number of Participants With Treatment-emergent Adverse Events (AEs) and Deaths

A serious adverse event is defined as an adverse event that meets at least one of the following serious criteria: • fatal, • life threatening, • requires in-patient hospitalization or prolongation of existing hospitalization, • results in persistent or significant disability/incapacity, • congenital anomaly/birth defect, and/or • other significant medical hazard. The adverse event severity grading scale used was the Common Terminology Criteria for Adverse Events (CTCAE) version 3.0, according to the following: Grade 1 = Mild AE; Grade 2 = Moderate AE; Grade 3 = Severe AE; Grade 4 = Life-threatening or disabling AE; Grade 5 = Death related to AE. The investigator assessed whether each adverse event was possibly related to the investigational product (IP).

Time frame: From the first dose of open-label denosumab until 4 weeks after the last; maximum time on study was 37 months. Follow-up survival information was collected for up to 3 years after the last dose of blinded investigation product in the 20050147 study.
