About this trial
Using the FREEDOM substudy as a benchmark, evaluate the effects of amorphous calcium carbonate (ACC) on bone mineral density (BMD) in postmenopausal women, both with and without the combination of Denosumab treatment.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Postmenopausal women who are 60 to 90 years of age.
Subject who are naïve to osteoporosis treatment or have received prior bisphosphonate treatment for less than 3 years and not within 12 months prior to screening visit.
A minimum of 2 evaluable lumbar vertebrae in the L1-L4 region and 1 evaluable hip (i.e., either the left or right side).
Willingness to limit additional Vitamin D3 intake to 400IU or 800IU per day during the study period.
Disqualifiers
Subjects who had conditions that influence bone metabolism (i.e., Paget's disease and osteomalacia).
Subject on other osteoporosis therapies, parathyroid hormone or its derivatives, corticosteroids, systemic hormone-replacement therapy, selective estrogen-receptor modulators, tibolone, calcitonin or calcitriol 6 weeks prior to screening visit.
Subjects had a serum 25-hydroxyvitamin D level of less than 12 ng/ml.
Subjects had a BMD T-score of less than -4.0 at the lumbar spine or total hip.

Treatment groups
Trial outcomes
Primary outcomes
Percentage change in LBMD
Percent change from baseline of bone mineral density (BMD) at the lumbar spine (L1, L2, L3, L4)
Secondary outcomes
Percentage change in BMD
Percent change from baseline of BMD at total hip, femoral neck, trochanter
Success rate in bone turnover markers (BTMs)
Percentage of Subjects with BTMs values, including P1NP and CTX, below the premenopausal reference interval at Month 0, 1, 6, 12, and 24. Premenopausal reference interval is defined as CTX values \<0.20 ng/mL and P1NP values \<17.4 ng/mL.
