Participant Flow

This study was conducted at 24 centers in Japan. The first participant was enrolled on 12 October 2012 and the last participant enrolled on 15 October 2013.

Participants were randomized in a 1:1:1:1 ratio to receive placebo or romosozumab 70, 140, or 210 mg subcutaneous (SC) injection every month (QM) for 12 months. Upon completion of the 12-month treatment period, participants were followed for another 3 months for assessment of antiromosozumab antibody formation (follow-up period).
