Osteoporosis Clinical Trial

Official title: A Phase IIb, Randomized, Double-Blind, Placebo- and Active-Controlled, Dose-Range-Finding Study to Evaluate the Effects of MK-5442 on Bone Mineral Density (BMD) in the Treatment of Osteoporosis in Postmenopausal Women Previously Treated With an Oral Bisphosphonate

Status Completed

Clinical Trial Summary

This study seeks to demonstrate that additional gain in bone mineral density (BMD) can be achieved by switching to MK-5442 from an oral bisphosphonate in participants who have been receiving oral bisphosphonate therapy for at least 3 years.

Clinical Trial Description

The study was originally planned for a duration of 2 years and included efficacy analysis of a 15 mg MK-5442 treatment arm. Amendment 1 of the protocol eliminated the 2nd year of the study as well the 15-mg arm. Enrollment into the 15-mg MK-5442 arm was stopped as a result of the amendment and all participants who had been randomly assigned to the MK-5442 15-mg treatment arm were discontinued from the study. ;
