Study Details

Study Description

Brief Summary

The main purpose of this study is to assess whether a locally-administered rhBMP-2/CPM injection can rapidly increase bone mass in subjects at high risk for osteoporotic fractures of the hip. All subjects will receive standard treatment for low bone mass, consisting of bisphosphonates, calcium, and vitamin D (all taken by mouth). Subjects that are randomly selected to receive treatment with rhBMP-2 will receive an injection directly into the hip. The injection is given in a surgery room using a light anesthesia.

Outcome Measures

Primary Outcome Measures

  1. Change From Baseline in Bone Mineral Density (BMD) Measured by Dual-Energy X-ray Absorptiometry (DXA) [Baseline, 12 months post dose]

    Evaluating local changes (expected increases) in BMD after administration of rhBMP-2/CPM, compared to those observed with systemic osteoporosis therapy alone. Alternatively, if changes in the total area surrounding the proximal femur are observed, bone mineral content (BMC) may instead be applied for the primary measure. BMD is defined as a derived measure of bone density, generated by dividing the bone mineral content value obtained from a bone densitometry technique (for example, DXA) by the total area of the region scanned.

  2. Time Course Distribution of Volumetric BMD for the Hip Under Study (HUS) for Total Hip [At Month 12]

    Time course distribution of volumetric Bone mineral density (BMD) for hip is assessed by volumetric Quantitative Computed Tomography (vQCT) technique which is a 4-detector spiral (helical) computed tomography (CT) scanner with designated calibration phantom, obtain a CT scan of the proximal femora (bilateral simultaneous acquisition with volumetric rendering) to identify the specified region of interests (ROIs) for volumetric parameter to be quantified, reconstruct images of both hips and send reconstructed data (in electronic format). The vQCT regions of interest are cortical, the subcortical and trabecular. Cortical and the subcortical BMD are distinguished from trabecular effects. Peeled trabecular BMD reflects the subtraction of the extended CPM. Integral BMD reflects the cortical, subcortical, and peeled trabecular regions (minus the extended Calcium phosphate matrix [CPM]).

  3. Timecourse Distribution of Volumetric Bone Mineral Density (BMD) for the Hip Under Study (HUS). Volume of Interest: Femoral Neck [At Month 12]

    Evaluating local changes (expected increases) in BMD after administration of rhBMP-2/CPM, compared to those observed with systemic osteoporosis therapy alone. Alternatively, if changes in the total area surrounding the proximal femur are observed, bone mineral content (BMC) may instead be applied for the primary measure.

Secondary Outcome Measures

  1. Summary of Volumetric Density of Cortical and Trabecular Bone Calculated by Quantitative Computed Tomography (vQTC) [24 months]

    Here, measurement of density of cortical and trabecular bone in various regions of interest (ROIs) in the femoral neck, proximal shaft, and individual trochanters and was calculated by Quantitative Computed Tomography (vQTC) in ROIs.

  2. Number Participant Responses to Injectability Questionnaire Injected Population [Participants were monitored after treatment administration (dosing period)]

    Investigator documents preparation of the study medication evaluates injectability and product placement relative to desired location (for participants in active treatment groups). Surgeon performing the injection had to complete the questionnaire that evaluates ease of preparing the study medication, ability to administer study medication, and ability for the study medication to remain in the location it was administered.

  3. Number of Participants With Any Significant Changes in Serum Biomarkers of Bone Turnover From Baseline [Baseline up to 12 months]

    Participants with significant change in serum biomarkers of bone formation and resorption from baseline are reported. Significant changes were judged by investigator.

  4. Percentage Change From Baseline in Areal Bone Mineral Density (BMD) for Contralateral Total Hip [36 months]

    Evaluating local changes (expected increases) in BMD after administration of rhBMP-2/CPM, compared to those observed with systemic osteoporosis therapy alone. The percentage change from baseline in BMD for total hip (assessed by DXA) is presented for the contralateral (untreated) hip below.
