NameTypeDescription
AVT03BIOLOGICALAVT03 (denosumab) is a recombinant fully human IgG2 monoclonal antibody to RANKL to be administered as a subcutaneous injection. Subjects in this arm received AVT03 60mg administered s.c. on Day 1 and at Month 6. At Month 12, subjects in the AVT03 arm received a third dose of AVT03 60 mg.
DenosumabBIOLOGICALProlia (denosumab) is a recombinant fully human IgG2 monoclonal antibody to RANKL developed to be administered as a subcutaneous injection. Subjects in this arm received 60mg of commercially available US-Prolia, administered s.c on Day 1 and at Month 6. At Month 12, subjects in the Prolia treatment group were re-randomized in a 1:1 ratio to receive either: * AVT03 60 mg administered s.c. on Day365. * Prolia 60 mg administered s.c. on Day365.
