A Study to Compare the Safety and Efficacy of Romosozumab (AMG 785) Versus Placebo in Men With Osteoporosis (BRIDGE)

May 3, 2019 updated by: Amgen

A Multicenter, Randomized, Double-blind, Placebo-controlled Study to Compare the Efficacy and Safety of Romosozumab With Placebo in Men With Osteoporosis

The study is designed to evaluate if treatment with romosozumab once a month for 12 months compared with placebo is effective in increasing bone mineral density (BMD) at the lumbar spine. Additionally, the study will assess the effect of treatment with romosozumab for 12 months compared with placebo on BMD at the femoral neck and total hip.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

55 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Inclusion Criteria:

  • Must be ambulatory male subjects ≥ 55 years to ≤ 90 years of age
  • Must have a BMD T score ≤ -2.50 at the spine or hip, or BMD T score ≤ -1.50 at the spine or hip and a history of fragility nonvertebral fracture or vertebral fracture.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Measure Description
Time Frame
Percent Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) at Month 12
Time Frame: Baseline and month 12
Lumbar spine bone mineral density (BMD) was measured by dual x-ray absorptiometry (DXA). DXA scans were analyzed by a central imaging center.
Baseline and month 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percent Change From Baseline in BMD at the Total Hip at Month 12
Time Frame: Baseline and month 12
Total hip bone mineral density was measured by dual x-ray absorptiometry (DXA). DXA scans were analyzed by a central imaging center.
Baseline and month 12

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 16, 2014

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
February 15, 2016

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
