Research Study Summary

Patients are needed to participate in a clinical research study of Denosumab 60 MG [Prolia] and Placebo Injection

Research Study Title

Effects of Denosumab on Bone Mineral Density, Markers of Bone Metabolism and Bone Microarchitecture in Women With Anorexia Nervosa: A Pilot Study


This protocol is a randomized, double-blind, placebo-controlled clinical trial which aims to investigate the effect of denosumab on BMD in women with anorexia nervosa. The investigators hypothesize that 6 months of denosumab administration will result in an increase in bone mineral density, decrease in markers of bone resorption and improvement in bone microarchitecture in osteopenic women with anorexia nervosa compared with placebo.
