E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Treatment of postmenopausal osteoporosis |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to determine whether denosumab (formerly known as AMG 162) treatment can reduce the number of postmenopausal osteoporotic women (BMD T-score below -2.5) with new vertebral fractures as compared with control (placebo plus vitamin D and calcium)
The primary safety objective is to characterize the safety and tolerability profile of denosumab in this population based on the adverse event incidence, changes in laboratory profiles, and immunogenicity to denosumab. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives will be to assess the effect of denosumab on time to first non-vertebral fracture and time to first hip fracture. |
|
E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
E.3 | Principal inclusion criteria |
- Postmenopausal women, between 60 and 90 years old - BMD T-score < –2.5 at one or more of the following regions: the lumbar spine, total hip, or femoral neck - Ethical - Before any study-specific procedure, the appropriate written informed consent must be obtained
|
|
E.4 | Principal exclusion criteria |
- BMD T-score < -4.0 at one or more of the following regions: Lumbar spine, total hip, or femoral neck - Oral bisphosphonate treatment for osteoporosis: Ineligible if used for 3 or more years cumulatively; If used for >3 months, but ≤ 3 years, at least a one year period since last dose is necessary for eligibility; If used ≤ 3 months at any time in the past, subject is eligible. - Administration of intravenous bisphosphonate, fluoride or strontium for osteoporosis within the last 5 years - Administration of any of the following treatments within the last 6 weeks: a) PTH or PTH derivatives, eg, teriparatide b) Anabolic steroids or testosterone c) Glucocorticosteroids (> 5 mg prednisone equivalent per day for more than 10 days) d) Systemic hormone replacement therapy e) Selective estrogen receptor modulators (SERMs), eg, raloxifene f) Tibolone g) Calcitonin h) Calcitriol - Evidence of any of the following per patient report, chart review, DXA, or X-ray review: a) Hyper or hypothyroidism; patients on stable thyroid treatment with a normal TSH will be allowed b) Current hyper- or hypoparathyroidism c) Current hypocalcemia (albumin adjusted serum calcium below 2.13 mmol/L [8.5 mg/dL]) d) Vitamin D deficiency [(25) hydroxy Vitamin D level < 12 ng/mL) e) Rheumatoid arthritis f) Paget’s disease g) Malignancy (except basal cell carcinoma, cervical or breast ductal carcinoma in situ) within the last 5 years h) Any bone disease, eg, osteomalacia or osteogenesis imperfecta, which may interfere with the interpretation of the findings i) Malabsorption syndrome j) Height, weight and girth which may preclude accurate DXA measurements k) Advanced scoliosis or extensive lumbar fusion which would preclude vertebral fracture assessment l) Any severe or more than 2 moderate vertebral fractures on spinal X-rays (see section 7.9) m) Less than 2 lumbar vertebrae (L1-L4) evaluable for DXA - Known sensitivity to mammalian cell derived drug products - Any organic or psychiatric disorder, or laboratory abnormality which, in the opinion of the investigator, will prevent the subject from completing the study or interfere with the interpretation of the study results - Evidence of alcohol or substance-abuse within the last 12 months that the investigator believes would interfere with understanding or completing the study - Subject has any kind of disorder that compromises the ability of the subject to give written informed consent and/or to comply with study procedures - For biopsy sub study subjects only: known or suspected sensitivity or contraindication to tetracycline derivatives - Subject is currently enrolled in or has not yet completed at least 30 days since ending other investigational device or drug trial(s), or subject is receiving other investigational agent(s).
