简要总结
The purpose of this study is to evaluate the long-term safety of paricalcitol injection. Subjects will administer clinical supplies 3 times a week, 40 weeks at dialysis session in dose-titration manner, following 12 weeks of treatment in the dose-response study, M10-309 (NCT00667576).
详细描述
The first 12-week period in this study was a dose-response study reported as Study M10-309 (NCT00667576). Only subjects who completed 12 weeks in NCT00667576 were enrolled into this study (M10-312). Baseline in this study was the same as Baseline in NCT00667576. The duration of treatment in Study M10-312 was 40 weeks (for a total of 52 weeks, including NCT00667576).

研究组 & 干预措施
Paricalcitol 2 µg ± 1 µg
Study drug was administered 3 times per week (no more frequently than every other day) intravenously immediately before the completion of hemodialysis. The initial dosage was administered for 2 weeks, with subsequent dosage adjustment based on the subject's iPTH, calcium (adjusted), and phosphorus levels every 2 weeks. Total duration of treatment was 48 weeks in this study, combined with 12 weeks in the previous study, M10-309 (NCT00667576), for a total of 52 weeks of treatment.
