E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objectives of this study are to evaluate
1. whether the efficacy of denosumab (60 mg subcutaneously every 6
months) manufactured by the proposed process referred to as CP4 is not inferior to that of denosumab manufactured by the currently approved commercial process referred to as CP2 based on the change in lumbar spine bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA) at 12 months in postmenopausal women with osteoporosis;
2. whether the efficacy of denosumab CP4 (60 mg subcutaneously every
6 months) is equivalent to that of denosumab CP2 based on the change
in lumbar spine BMD by DXA at 12 months in postmenopausal women
with osteoporosis. |
|
E.2.2 | Secondary objectives of the trial |
To compare the change in bone turnover marker levels over 12 months
in subjects administered denosumab manufactured by 2 different
processes in postmenopausal women with osteoporosis. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Ambulatory postmenopausal women. Ambulatory is defined as women who are able to walk, not bedridden; postmenopause is defined as no vaginal bleeding or spotting for at least 12 months prior to screening.
• Age ≥ 55 years
• Screening bone mineral density (g/cm2) values (by DXA) at the
lumbar spine values equal to or less than 0.880 GE Lunar, 0.772 Hologic.
Screening bone mineral density (g/cm2) values (by DXA) at the
total hip values equal to or less than 0.693 GE Lunar, 0.637 Hologic.
Screening bone mineral density (g/cm2) values (by DXA) at the
femoral neck values equal to or less than 0.692 GE Lunar, 0.558 Hologic.
Both the initial and the repeat DXA assessments at baseline of the
lumbar spine OR the total hip OR the femoral neck must meet the above eligibility criteria.
Eligibility will be determined by a local reading of the DXAs at the
investigator's site. At least 2 lumbar vertebrae must be evaluable by
DXA.
• Subject's legally acceptable representative has provided informed
consent prior to any study-specific activities/procedures being initiated
when the subject has any kind of condition that, in the opinion of the
investigator, may compromise the ability of the subject to give written
informed consent. |

hormone (ACTH), cinacalcet, aluminum, lithium, protease inhibitors,
gonadotropin releasing hormone agonists

controlled hypo- or hyperthyroidism may be eligible, provided that they
have been on a stable therapy for at least 3 months (per subject
report)).
. hypo- or hyperparathyroidism
. known to have tested positive for human immunodeficiency virus,
hepatitis C virus, or hepatitis B surface antigen
. osteomalacia (chart review)
. osteonecrosis of the jaw (ONJ) or risk factors for ONJ such as invasive
dental procedures (eg, dental implants, oral surgery in the past 6
months), poor oral hygiene, periodontal and/or pre-existing dental
disease
. recent tooth extraction (within 6 months of screening visit)
. Paget's disease of bone (subject report or chart review)
. Rheumatoid arthritis
. other bone diseases which affect bone metabolism (eg, osteopetrosis,
osteogenesis imperfecta) (chart review)
• Vitamin D deficiency (25[OH] vitamin D level < 20 ng/mL)
• Creatinine clearance (calculated using the Cockcroft-Gault equation)
of < 30 mL/min, or evidence of acute renal impairment
• Abnormalities of the following per central laboratory reference
ranges:
. hypocalcemia or hypercalcemia
. elevated transaminases ≥ 2.0 x upper limits of normal (ULN)
• History of any solid organ or bone marrow transplant

basal cell carcinoma, or cervical or breast ductal carcinoma in situ)
• Contraindicated or poorly tolerant of denosumab therapy;
contraindications include
. hypocalcemia
. hypersensitivity to drug or any component of the drug
• Known intolerance to calcium or vitamin D supplements
• Self reported alcohol or drug abuse within 12 months prior to
screening
• Any disorder that compromises ability to give truly informed consent
for participation in this study
• Currently enrolled in or has not yet completed at least 1 month since
ending other investigational device or drug trial(s), or subject is
receiving other investigational agent(s)
• Subject has known sensitivity to any of the products to be
administered during dosing
• Subject likely to not be available to complete all protocol-required
study visits or procedures, and/or to comply with all required study
procedures to the best of the subject's and investigator's knowledge
• History or evidence of any other clinically significant disorder,
condition or disease (with the exception of those outlined above) that, in the opinion of the investigator or Amgen physician, if consulted, would pose a risk to subject safety or interfere with the study evaluation, procedures, or completion
• Subject previously has entered this study or any clinical trial involving
denosumab |
