Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Recruitment for the study started in the US, in January 2007. For the initial 24-week treatment period, patients were randomized to study treatment at 30 study centers in the US, Argentina, India and the UK . Eleven of the 30 study centers treated patients in the 24-week treatment extension period in the US, Argentina, and India.

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
After eligibility was established, patients entered a 4-week Pretreatment Period during which they received daily Calcium and Vitamin D supplements, were trained in self-injection with the pen devices, and were assessed for additional evaluations at the end of the Pretreatment Period. Patients who remained eligible were randomized on Day 1.
