Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to test a new vitamin D compound for its ability to reduce parathyroid hormone levels in patients who are on hemodialysis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a randomized, double-blind, placebo-controlled study of the vitamin D analog 2-methylene-19-nor-20S-1α,25-dihydroxyvitamin D3 (DP001) in patients with end-stage renal disease (ESRD). The effect of 12 weeks of oral administration of DP001 on serum parathyroid hormone (PTH) levels will be evaluated in ESRD patients who have secondary hyperparathyroidism.
