Primary Outcome Measures
NameTimeMethod
Percent Change From Baseline to Week 13 in Creatinine-adjusted Urinary N-telopeptide (uNTx/Cr)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
NameTimeMethod
Number of Participants Achieving 65% or More Reduction in Urinary N-telopeptide (uNTx) From Baseline at Week 13Baseline 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%.

Percent Change From Baseline to Week 25 in Urinary N-telopeptide (uNTx)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 uNTX From Baseline at Week 25Baseline 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 BaselineBaseline 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)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)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)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 P1NPBaseline 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)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)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)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)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 OsteocalcinBaseline 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 OsteocalcinBaseline and Week 25

Percent change from Baseline to Week 25 in osteocalcin calculated using ((Week 25 value - Baseline value) / Baseline value) x 100.
