Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline in Lumbar Spine Bone Mineral Density (BMD) Z-Score at 12 Months	Lumbar spine BMD was measured by dual-energy X-ray absorptiometry (DXA) adjusted for age, sex, and race/ethnicity. The results were then converted to Z-scores. The Z-score indicated the number of standard deviations away from the reference population and a score of 0 is equal to the mean. Positive changes from Baseline indicated an improvement in lumbar spine BMD.	Baseline and 12 months
Secondary	Change From Baseline in Lumbar Spine BMD Z-score at 6 Months	Lumbar spine BMD was measured by DXA adjusted for age, sex, and race/ethnicity. The results were then converted to Z-scores. The Z-score indicated the number of standard deviations away from the reference population and a score of 0 is equal to the mean. Positive changes from Baseline indicated an improvement in lumbar spine BMD.	Baseline and 6 months
Secondary	Change From Baseline in Proximal Femur BMD Z-score at 6 and 12 Months	Proximal femur (total hip and femoral neck) BMD Z-score was measured by DXA adjusted for age, sex, and race/ethnicity. The results were then converted to Z-scores. The Z-score indicated the number of standard deviations away from the reference population and a score of 0 is equal to the mean. Positive changes from Baseline indicated an improvement in lumbar spine BMD.	Baseline, 6 and 12 months
Secondary	Percentage of Participants With at Least 1 X-ray Confirmed Long Bone or New and Worsening Vertebral Fracture		Q6M Dosing Regimen: Last 12 months of treatment (median treatment duration was 730.0 days); Q3M Dosing Regimen: Day 1 up to 12 months
Secondary	Percentage of Participants With at Least 1 X-ray Confirmed New and Worsening Vertebral Fracture		Q6M Dosing Regimen: Last 12 months of treatment (median treatment duration was 730.0 days); Q3M Dosing Regimen: Day 1 up to 12 months
Secondary	Percentage of Participants With at Least 1 X-ray Confirmed New Vertebral Fracture		Q6M Dosing Regimen: Last 12 months of treatment (median treatment duration was 730.0 days); Q3M Dosing Regimen: Day 1 up to 12 months
Secondary	Percentage of Participants Wth at Least 1 X-ray Confirmed Improving Vertebral Fracture		Q3M Dosing Regimen: Baseline up to 12 months
Secondary	Percentage of Participants With at Least 1 Vertebral and Nonvertebral Fracture		Q6M Dosing Regimen: Last 12 months of treatment (median treatment duration was 730.0 days); Q3M Dosing Regimen: Day 1 up to 12 months
Secondary	Change From Baseline in Child Health Questionnaire-Parent Form Physical Summary Score (CHQ-PF-50) at 12 Months	The CHQ-PF-50 was a 50-item questionnaire completed by the parents or guardians of children between 5 and 18 years of age. The 50 questions measure 14 domains which were summarized as the physical and psychological summary scores. Each summary score was transformed and could range from 0 to 100, with higher score indicating better physical and psychosocial health. A negative change from Baseline indicates decreased well-being.	Baseline and 12 months
Secondary	Change From Baseline in CHQ-PF-50 Psychological Summary Score at 12 Months	The CHQ-PF-50 was a 50-item questionnaire completed by the parents or guardians of children between 5 and 18 years of age. The 50 questions measure 14 domains which were summarized as the physical and psychological summary scores. Each summary score was transformed and could range from 0 to 100, with higher score indicating better physical and psychosocial health. A positive change from Baseline indicates improved well-being.	Baseline and 12 months
Secondary	Change From Baseline in Childhood Health Assessment Questionnaire (CHAQ) Disability Index Score at 12 Months	The disability domain (questions 1-54) of the CHAQ was used to measure the participant's assessment of physical functioning or the parent's assessment of the child's physical functioning. The disability index comprised of 8 categories (dressing and grooming, arising, eating, walking, hygiene, reaching, gripping, and activities). Scoring ranged from 1 to 5; 1 was "without any difficulty," 2 was "with some difficulty," 3 was "with much difficulty," and 4 was "unable to do." An answer of "not applicable" was scored as a 5, but was not counted. If a child required assistance from another person or used an aid or other device for any of the 8 categories, the minimum score for that category was recorded as a 3. The CHAQ questions were scored and converted to a total index score ranging from 0 to 3. Negative change from Baseline indicates an improvement.	Baseline and 12 months
Secondary	Change From Baseline in Wong-Baker Faces Pain Rating Scale (WBFPRS) at 12 Months	Participants were asked to report their level of pain by choosing a face that best described their own pain (the corresponding number: 0, 2, 4, 6, 8, 10) were then recorded. The WBFPRS ranged from 0, "no hurt," to 10, "hurts worst". A negative change from baseline indicates an improvement.	Baseline and 12 months
Secondary	Serum Concentration of Denosumab		Days 1 (predose), 10, 30, and 60, & weeks 12, 24, 36, 48, 60, 72 (end of study visit), early termination visit, & follow-up visit 12 weeks after last dose (average duration of treatment: 231 days)
Secondary	Serum Bone Turnover Marker (BTM) - Serum Type I Collagen C Telopeptide		Baseline and Days 10 and 30, and Months 3, 6, 9, 12, 15 and 18
Secondary	BTM - Bone-specific Alkaline Phosphatase (BSAP)		Baseline and Days 10 and 30, and Months 3, 6, 9, 12, and 15
Secondary	Change From Baseline in Growth Velocity at 12 Months	Change from baseline in growth velocity was determined by calculating age-adjusted Z-scores for height, weight and body mass index (BMI).; Height-for-age Z-score was defined as the difference between the participant's height and the median height for the population with the same age and gender, divided by the population standard deviation.; The definitions of growth velocity based on weight and BMI were analogously calculated. To programmatically calculate the Z-scores, the National Center for Health Statistics percentiles growth charts, based on the 2000 Center for Disease Control and Prevention (CDC) (http://www.cdc.gov/growthcharts/c c_charts.htm), and the CDC Anthropometric Software Package 3.0 Z-scores were used.; During normal growth, the change in z-score for each of the three should equal 0. A positive change in any of the three indicates growth acceleration, whereas a negative change indicates deceleration.	Baseline and 12 months
