Primary: Number of Participants With Clinically Significant Hypocalcemia, Clinically significant hypocalcemia is defined as albumin-adjusted calcium \< 7.0 mg/dL or symptomatic hypocalcemia. Symptomatic hypocalcemiais is defined as both a clinical adverse event of hypocalcemia and a concomitant symptom of hypocalcemia (e.g., hypoesthesia, paresthesia, muscle cramps, seizure, prolonged QT interval) that occurred along with the hypocalcemia event or decreased serum calcium levels., 113 days | Secondary: Number of Participants With Hypocalcemia Determined by CTCAE v.4.0 Criteria, The severity of hypocalcemia (a low concentration of calcium, corrected for albumin, in the blood) was graded according to the common terminology criteria for adverse events (CTCAE) v.4.0 criteria: Grade 1: albumin-adjusted serum calcium \< lower limit of normal (LLN; 9.2 mg/dL) to 8.0 mg/dL; Grade 2: albumin-adjusted serum calcium \< 8.0 to 7.0 mg/dL; Grade 3: albumin-adjusted serum calcium \< 7.0 to 6.0 mg/dL; Grade 4: albumin-adjusted serum calcium \< 6.0 mg/dL., 113 days|Number of Participants With Hypophosphatemia Determined by CTCAE v.4.0 Criteria, The severity of hypophosphatemia (a low concentration of phosphates in the blood) was graded according to the common terminology criteria for adverse events (CTCAE) v.4.0 criteria: Grade 1: \< LLN (3 mg/dL) - 2.5 mg/dL; Grade 2: \< 2.5 - 2.0 mg/dL; Grade 3: \< 2.0 - 1.0 mg/dL; Grade 4: \< 1.0 mg/dL., 113 days|Number of Participants With Hypomagnesemia Determined by CTCAE v.4.0 Criteria, The severity of hypomagnesemia (a low concentration of magnesium in the blood) was graded according to the common terminology criteria for adverse events (CTCAE) v.4.0 criteria: Grade 1: \< LLN (1.5 mg/dL) - 1.2 mg/dL; Grade 2: \< 1.2 - 0.9 mg/dL; Grade 3: \< 0.9 - 0.7 mg/dL; Grade 4: \< 0.7 mg/dL., 113 days|Percent Change From Baseline in Albumin-adjusted Serum Calcium Over Time, Baseline and Days 2, 3, 6, 8, 11, 15, 22, 29, 30, 31, 34, 36, 39, 43, 57, 71, 85, and 113|Percent Change From Baseline in Serum Phosphorus Over Time, Baseline and Days 2, 3, 6, 8, 11, 15, 22, 29, 30, 31, 34, 36, 39, 43, 57, 71, 85, and 113|Percent Change From Baseline in Serum Magnesium Over Time, Baseline and Days 2, 3, 6, 8, 11, 15, 22, 29, 30, 31, 34, 36, 39, 43, 57, 71, 85, and 113|Number of Participants With Adverse Events, The severity of each adverse event (AE) was graded using the Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0. The investigator assessed whether AEs were possibly related to study drug by answering the question: "Is there a reasonable possibility that the event may have been caused by the investigational product?" Abnormal laboratory findings without clinical significance (based on the investigator's judgment) were not recorded as AEs, however, laboratory value changes that required treatment or adjustment in current therapy were considered AEs. A serious adverse event is defined as an adverse event that meets at least 1 of the following serious criteria: • fatal, • life-threatening (places the participant at immediate risk of death), • requires in-patient hospitalization or prolongation of existing hospitalization, • results in persistent or significant disability/incapacity, • congenital anomaly/birth defect, and/or • other medically important serious event., 113 days|Maximum Observed Serum Denosumab Concentration (Cmax), Serum concentrations of denosumab were measured by an enzyme-linked immunosorbent assay (ELISA). The lower limit of quantification (LLOQ) was 20 ng/mL., Days 1 and 29 (predose), and on Days 8, 15, 36, 43, 57, 71, 85, and 113|Time to Maximum Observed Serum Denosumab Concentration (Tmax), Serum concentrations of denosumab were measured by an enzyme-linked immunosorbent assay (ELISA). The lower limit of quantification (LLOQ) was 20 ng/mL., Days 1 and 29 (predose), and on Days 8, 15, 36, 43, 57, 71, 85, and 113|Area Under the Serum Concentration-time Curve From Time 0 to 4 Weeks (AUC0-4wks) After Dose 1, Estimated using the linear trapezoidal method., Days 1, 8, 15, and 29 (predose)|Area Under the Serum Concentration-time Curve From Time 0 to 12 Weeks (AUC0-12wks) After Dose 2, Estimated using the linear trapezoidal method., Days 29 (predose), 36, 43, 57, 71, and 85|Percent Change From Baseline in Serum C-Telopeptide Over Time, Baseline and Days 1 and 29 (predose), and on Days 8, 15, 36, 43, 57, 71, 85, and 113|Number of Participants Who Developed Anti-denosumab Antibodies, From Day 1 (predose) to Day 113
