Primary Outcome Measures:
  • Percent Change From Baseline to Week 13 in Creatinine-adjusted Urinary N-telopeptide (uNTx/Cr) [ Time Frame: Baseline and Week 13 ]
    Percent change from Baseline to Week 13 in Urinary N-telopeptide corrected by creatinine (uNTx/Cr) calculated using ((Week 13 value - Baseline value) / Baseline value ) x 100.


Secondary Outcome Measures:
  • Percent Change From Baseline to Week 25 in Urinary N-telopeptide (uNTx) [ Time Frame: Baseline and Week 25 ]
    Percent change from Baseline to Week 25 in Urinary N-telopeptide (uNTx) calculated using ((Week 25 value - Baseline value) / Baseline value) x 100.

  • Number of Participants Achieving 65% or More Reduction in Urinary N-telopeptide (uNTx) From Baseline at Week 13 [ Time Frame: Baseline and Week 13 ]
    The number of participants achieving a 65% reduction or more in uNTx from Baseline at Week 13. Calculation used is ((Week 13 value - Baseline value) / Baseline value ) x 100 and participants were considered having a 65% reduction or more if their value was ≤ -65%.

  • Number of Participants Achieving 65% or More Reduction in uNTX From Baseline at Week 25 [ Time Frame: Baseline and Week 25 ]
    The number of participants achieving a 65% reduction or more in uNTX from Baseline at Week 25. Calculation used is ((Week 25 value - Baseline value) / Baseline value) x 100 and participants were considered having a 65% reduction or more if their value was ≤ -65%.

  • Time to 65% or More Reduction in Urinary N-telopeptide (uNTX) From Baseline [ Time Frame: Baseline to Week 57 ]
    Kaplan-Meier estimate of the median time from enrollment to the first occurrence of a reduction of uNTx of ≥ 65% compared to Baseline. For participants whose uNTx did not fall below 65% of the Baseline value, the time was censored at time of last evaluation of uNTx.

  • Percent Change From Baseline to Week 13 in Serum C-Telopeptide (CTX) [ Time Frame: Baseline and week 13 ]
    Percent change from Baseline to Week 13 in type I serum C-telopeptide (CTX) calculated using ((Week 13 value - Baseline value) / Baseline value) x 100.

  • Percent Change From Baseline to Week 25 in Serum C-telopeptide (CTX) [ Time Frame: Baseline and Week 25 ]
    Percent change from Baseline to Week 25 in type I serum C-telopeptide calculated using ((Week 25 value - Baseline value) / Baseline value) x 100.

  • Percent Change From Baseline to Week 13 in Procollagen I N-terminal Peptide (P1NP) [ Time Frame: Baseline and Week 13 ]
    Percent change from Baseline to Week 13 in procollagen 1 N-terminal peptide calculated using ((Week 13 value - Baseline value) / Baseline value) x 100.

  • Percent Change From Baseline to Week 25 in P1NP [ Time Frame: Baseline and Week 25 ]
    Percent change from Baseline to Week 25 in procollagen 1 N-terminal peptide (P1NP) calculated using ((Week 25 value - Baseline value) / Baseline value ) x 100.

  • Percent Change From Baseline to Week 13 in Tartrate-resistant Acid Phosphatase 5b (TRAP5b) [ Time Frame: Baseline and Week 13 ]
    Percent change from Baseline to Week 13 in tartrate-resistant acid phosphatase 5b calculated using ((Week 13 value - Baseline value) / Baseline value) x 100.

  • Percent Change From Baseline to Week 25 in Tartrate-resistant Acid Phosphatase 5b (TRAP5b) [ Time Frame: Baseline and Week 25 ]
    Percent change from Baseline to Week 25 in TRAP5b calculated using ((Week 25 value - Baseline value) / Baseline value) x 100.

  • Percent Change From Baseline to Week 13 in Bone Specific Alkaline Phosphatase (BSAP) [ Time Frame: Baseline and Week 13 ]
    Percent change from Baseline to Week 13 in bone specific alkaline phosphatase (BSAP) calculated using ((Week 13 value - Baseline value) / Baseline value) x 100.

  • Percent Change From Baseline to Week 25 in Bone Specific Alkaline Phosphatase (BSAP) [ Time Frame: Baseline and Week 25 ]
    Percent change from Baseline to Week 25 in BSAP calculated using ((Week 25 value - Baseline value) / Baseline value) x 100.

  • Percent Change From Baseline to Week 13 in Osteocalcin [ Time Frame: Baseline and Week 13 ]
    Percent change from Baseline to Week 13 in osteocalcin calculated using ((Week 13 value - Baseline value) / Baseline value ) x 100.

  • Percent Change From Baseline to Week 25 in Osteocalcin [ Time Frame: Baseline and Week 25 ]
    Percent change from Baseline to Week 25 in osteocalcin calculated using ((Week 25 value - Baseline value) / Baseline value) x 100.

  • Time to First Skeletal Related Event [ Time Frame: Day 1 to Week 25 ]
    Skeletal Related Event (SRE) defined as ≥ 1 of the following: pathological bone fracture, spinal cord compression, surgery or radiation therapy to bone (including the use of radioisotopes).

  • Number of Participants With Skeletal Related Events [ Time Frame: From Day 1 to Week 25 ]
    Skeletal Related Events (SRE) are defined as ≥ 1 of the following: pathological bone fracture, spinal cord compression, surgery or radiation therapy to bone (including the use of radioisotopes).

  • Number of Participants With Hypercalcemia [ Time Frame: Day 1 to Week 57 ]
    Occurrence of grade 3 or 4 hypercalcemia according to the Common Terminology Criteria for Adverse Events (CTCAE) v3. A summary of hypercalcemia events is reported under adverse events.
