Measure
SB16
Subjects were randomly assigned to receive SB16 subcutaneously 60 mg at Months 0 and 6.
Prolia
Subjects were randomly assigned to receive Prolia subcutaneously 60 mg at Months 0 and 6.
SB16+SB16
Subjects were randomly assigned to receive SB16 subcutaneously 60 mg at Months 0 and 6. At Month 12, subjects who received SB16 in the Main period continued to receive SB16, but they also followed the randomisation procedure to maintain blinding.
Prolia+SB16
Subjects were randomly assigned to receive Prolia subcutaneously 60 mg at Months 0 and 6. At Month 12, subjects who received Prolia in the Main period of the SB16-3001 study were randomised again in a 1:1 ratio to either continue on Prolia (Prolia+Prolia) or were transitioned to SB16 (Prolia+SB16).
Prolia+Prolia
Subjects were randomly assigned to receive Prolia subcutaneously 60 mg at Months 0 and 6. At Month 12, subjects who received Prolia in the Main period of the SB16-3001 study were randomised again in a 1:1 ratio to either continue on Prolia (Prolia+Prolia) or were transitioned to SB16 (Prolia+SB16).

SB16
n=225 participants at risk
Subjects were randomly assigned to receive SB16 subcutaneously 60 mg at Months 0 and 6. At Month 12, subjects who received SB16 in the Main period continued to receive SB16, but they also followed the randomisation procedure to maintain blinding.
Prolia Overall
n=231 participants at risk
Prolia Overall include subjects who had randomised to Prolia at Month 0 and had re-randomisation (Prolia+SB16 or Prolia+Prolia) at Month 12. Prolia+SB16 and Prolia+Prolia may not add up to Prolia Overall.
