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.

Condition or disease Intervention/treatment Phase
Osteoporosis Drug: rhBMP-2/CPM injection and bisphosphonates, calcium, and vitamin D (oral bisphosphonate therapy) Drug: bisphosphonates, calcium, and vitamin D Phase 2

Outcome Measures

Primary Outcome Measures :
  1. Changes in Bone Mineral Density will be measured by dual-energy x-ray absorptiometry [ Time Frame: 12 months ]

Secondary Outcome Measures :
  1. Safety of injecting rhBMP-2/CPM, measured by physical exams and other tests such as radiographs and electrocardiograms. [ Time Frame: 36 months ]
  2. Feasibility of administering rhBMP-2/CPM as a minimally invasive technique in an outpatient (ambulatory care) setting. [ Time Frame: Dosing ]
  3. Evaluate long-term changes in BMD after injection of rhBMP-2/CPM. [ Time Frame: 36 Months ]
  4. Evaluate bone quality with emphasis on cortical thickness and trabecular volume in region(s) of interest, utilizing quantitative computed tomography. [ Time Frame: 24 Months ]
  5. Evaluate changes in biochemical markers of bone turnover to identify markers that are predictive of changes in BMD from baseline. [ Time Frame: 12 Months ]

Ages Eligible for Study:   65 Years to 85 Years   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Community-dwelling, ambulatory (with or without assistive device), postmenopausal females, age greater than 65 years.
  • BMD T-score (total hip or femoral neck) of -2.5 or less in at least 1 hip. Subjects with BMD T-scores of -2.0 or less may be enrolled if at least one of the following risk factors is also present:
  • Age greater than 75 years
  • Family (maternal) history of fragility fracture
  • Previous fragility fracture (self) after age 45
  • Subjects may either be treatment naïve or on a previously-established regimen ( greater than 1year, but less than 5 years duration) of bisphosphonate therapy. Subjects must be willing to comply with 1of the 3 protocol-designated oral bisphosphonates (risedronate, alendronate, or ibandronate sodium) with risedronate considered as first-line therapy.

Exclusion Criteria:

  • Metabolic bone disorder or disease affecting bone and mineral metabolism (eg, Paget's disease, vitamin D deficiency [ less than 20 ng/mL], hyperparathyroidism, renal osteodystrophy, osteomalacia, hypocalcemia, hypercalcemia).
  • Coagulopathy and/or history of venous thromboembolic events (deep vein thrombosis, pulmonary embolus, retinal vein thrombosis) within the past 12 months.
  • Inflammatory arthritis including rheumatoid, psoriatic, or crystal-induced (gouty) arthritis, or those associated with systemic lupus erythematosus (SLE), spondyloarthropathy, Reiters syndrome, or Crohns disease.
