Brief Summary

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

This study will evaluate the effect of a 1-year administration of the vitamin D analog 2-methylene-19-nor-(20S)-1alpha, 25-dihydroxyvitamin D3 (DP001) on bone mineral density (BMD), safety, and tolerability.

Detailed Description

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

DP001 is a vitamin D analog that has been shown to stimulate bone formation in pre-clinical studies. In a Phase 1B study of postmenopausal women, an increase in the bone formation marker, osteocalcin, was evident without an increase in serum calcium. The aim of this study is to determine if 1-year administration of DP001 to postmenopausal women with osteopenia results in a significant increase in BMD at doses that are safe and well tolerated.
