Brief Summary
This is an open-label, dose-ranging study of the vitamin D analog DP001 in patients with end-stage renal disease (ESRD). The primary goals of this 4-week Phase 2A study are to identify an appropriate starting dose of DP001 to be used in subsequent studies in this population and for evaluation of pharmacokinetics of DP001 in ESRD patients.
