Drug: Placebo
Registration Number
NCT03512262
Lead Sponsor

Brief Summary

A 12-month study to measure the efficacy and safety of abaloparatide in men with osteoporosis.

Detailed Description

The primary objective of this prospective controlled study is to evaluate the efficacy and the safety of abaloparatide 80 micrograms (mcg) per day administered subcutaneously (SC) compared to placebo in men with osteoporosis. Efficacy was primarily assessed by the change in bone mineral density (BMD) over 12 months.

Primary Outcome Measures
NameTimeMethod
Percent Change From Baseline in Lumbar Spine BMD at Month 12Baseline, Month 12

Lumbar Spine BMD was assessed by DXA scans evaluated by a central imaging laboratory. Lumbar spine scans included L1 through L4. Positive changes from baseline indicate improvement in bone health.

Secondary Outcome Measures
NameTimeMethod
Percent Change From Baseline in Total Hip Volumetric BMD as Measured by Quantitative Computed Tomography (QCT) at Month 12Baseline, Month 12

QCT scans were evaluated by a central imaging laboratory.

Percent Change in Total Hip BMD From Baseline at Month 6Baseline, Month 6

Total hip BMD was assessed by DXA scans evaluated by a central imaging laboratory. Positive changes from baseline indicate improvement in bone health.

Percent Change From Baseline in Ultra-Distal Radius BMD at Month 12Baseline, Month 12

Ultra-distal radius BMD was assessed by DXA scans. Positive changes from baseline indicate improvement in bone health.

Percent Change From Baseline in Total Hip BMD at Month 12Baseline, Month 12

Total hip BMD was assessed by DXA scans evaluated by a central imaging laboratory. Positive changes from baseline indicate improvement in bone health.

Percent Change From Baseline in Femoral Neck BMD at Month 12Baseline, Month 12

Femoral neck BMD was assessed by DXA scans evaluated by a central imaging laboratory. Positive changes from baseline indicate improvement in bone health.

Percent Change From Baseline in Serum Carboxy-terminal Cross-linking Telopeptide of Type I Collagen (s-CTX) at Month 12Baseline, Month 12

Blood samples were taken to measure s-CTX. Elevated levels of s-CTX indicate increased bone resorption (bone loss).

Number of Participants With New Clinical FracturesBaseline through Month 12

Radiological evaluations were performed to identify any new clinical fractures (occurring after the screening visit).

Percent of Participants With Change in Disease StatusBaseline through Month 12

The percentage of participants converting from the categories of osteoporosis to osteopenia or from osteopenia to normal at End of Treatment (Month 12) was assessed. Osteoporosis was defined as lumbar spine or total hip BMD T-score ≤ -2.5. Osteopenia was defined as one of the following:

* Lumbar spine \> -2.5 and total hip BMD T-score \> -2.5 and \< -1.0

* Lumbar spine \> -2.5 and \< -1.0 and total hip BMD T-score \> -2.5

* Normal was defined as lumbar spine and total hip BMD T-score ≥ -1.0.

Percent of Participants Experiencing BMD Gains From Baseline of > 0%, > 3%, and > 6% at the Lumbar Spine, Femoral Neck, and Total HipMonth 12

Lumbar spine, femoral neck, and total hip BMD were assessed by DXA scans evaluated by a central imaging laboratory.

Percent Change From Baseline in Femoral Neck Volumetric BMD as Measured by QCT at Month 12Baseline, Month 12

QCT scans were evaluated by a central imaging laboratory.

Percent Change From Baseline in Lumbar Spine BMD at Month 6Baseline, Month 6

Lumbar Spine BMD was assessed by DXA scans evaluated by a central imaging laboratory. Lumbar spine scans included L1 through L4. Positive changes from baseline indicate improvement in bone health.

Percent Change From Baseline in Serum Procollagen Type I N-terminal Propeptide (s-PINP) at Month 12Baseline, Month 12

Blood samples were taken to measure s-PINP, a bone formation marker. s-PINP concentrations reflect the rate of skeletal new bone formation. Increases in s-PINP indicate anabolic biologic response in the bone.

Percent Change From Baseline in Femoral Neck BMD at Month 6Baseline, Month 6

Femoral neck BMD was assessed by DXA scans evaluated by a central imaging laboratory. Positive changes from baseline indicate improvement in bone health.

Percent Change From Baseline in Distal One-third Radius BMD at Month 12Baseline, Month 12

Distal one-third radius BMD was assessed by DXA scans. Positive changes from baseline indicate improvement in bone health.
