    • Any doses received within 3 months prior to randomization
    • More than 1 month of cumulative use between 3 and 12 months prior to randomization

  • Subject has used systemic oral or transdermal estrogen or selective estrogen receptor modulators (SERMs):

    ● More than 1 month of cumulative use within 6 months prior to randomization

  • Subject has used strontium ranelate or fluoride:

    ● More than 1 month of cumulative use within 5 years prior to randomization

  • Subject has used hormonal ablation therapy:

    ● More than 1 month of cumulative use within 6 months prior to randomization

  • Subject has used systemic glucocorticosteroids:

    ● ≥5mg prednisone equivalent per day for more than 14 days within 3 months prior to randomization

  • Subject has a history of osteonecrosis of the jaw (ONJ) or atypical femoral fracture (AFF)

  • Subject has evidence of any of the following:

    1. Current, uncontrolled hyper- or hypothyroidism. Uncontrolled hyperthyroidism is defined as thyroid-stimulating hormone (TSH) and thyroxine (T4) outside of the normal range. Uncontrolled hypothyroidism is defined as TSH >10
    2. Current, uncontrolled hyperparathyroidism or history of hypoparathyroidism. Uncontrolled hyperparathyroidism is defined as PTH outside the normal range in subjects with concurrent hypercalcemia or PTH values >20 % above upper limit of normal (ULN) in normocalcemic subjects
    3. Current hypercalcemia or hypocalcemia, defined as albumin-adjusted serum calcium outside the normal range, as assessed by the central laboratory at the time of Screening. Albumin-adjusted serum calcium levels may be retested once in case of an elevated albumin-adjusted serum calcium level within 1.1xULN of the laboratory's reference ranges
    4. Subject has ≥3xULN of any of the following: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), or >ULN total bilirubin (≥1.5xULN total bilirubin if known Gilbert's syndrome). If subject has elevations only in total bilirubin that are >ULN and <1.5xULN, fractionate bilirubin to identify possible undiagnosed Gilbert's syndrome (ie, direct bilirubin <35 %)

Primary Outcome Measures

Percent Change From Baseline in Bone Mineral Density (BMD) at the Lumbar Spine to the End of Double-Blind PeriodFrom Baseline (Day 1) to the end of the Double-blind Period (Month 6)

Percent change from baseline in BMD at the lumbar spine was assessed by dual-energy x-ray absorptiometry (DXA) at 6 months. Missing postbaseline BMD other than due to COVID-19 were imputed using the last observation carried forward (LOCF) approach. Missing or out of window (exceed 70 days since previous IMP) post-baseline DXA BMD due to COVID-19 were set to ...

Percentage of Participants With Treatment-emergent Adverse Events (TEAEs) During the Double-Blind PeriodFrom Baseline to the end of the Double-blind Period (Month 6)

An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a IMP, whether or ...

Percentage of Participants With Treatment-emergent Adverse Events for Romosozumab During Overall PeriodFrom Month 7 up to Month 12 (Placebo/Romo) and From Day 1 up to Month 12 (Romo/Romo) + 3-month SFU (up to Month 15)

An AE is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with use of a IMP, whether or not related to IMP. TEAE...
