T-scores are standardized scores that reflect the standard deviations (SDs) above/below the normal mean for young adults.
A score of 50 indicates the population mean with a standard deviation of 10.
A positive change in DXA T-score indicates an improvement in BMD.

The SF-12 is a generic, 12-item survey that measures 8 domains of health: physical functioning, role limitations due to physical health, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health.
It yields scale scores for each of these 8 domains and 2 summary measures of physical and mental health: The Physical Component Summary and the Mental Component Summary.
The total score for the Physical Component Summary ranges from 0 to 100, where higher scores reflect better physical functioning.

Change From Baseline in Index (Utility) Score on EuroQol 5-Dimension 5-Level Descriptive System (EQ-5D-5L) Score at Months 6 and 12
Time Frame: Baseline, Months 6 and 12 (EOT)
|
The EQ-5D-5L is a standardised measure of health status comprised of a descriptive system of 5 health-related quality of life states (i.e., mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and a Visual Analogue Scale (VAS) of overall health.
Each dimension is rated on a 5-point response scale indicating severity of problems, where 1 is "no problems" and 5 is "extreme problems".
The 5 questions are scored and together contribute to the EQ-5D index (utility) score between 0 and 1 (1 being perfect health).

Percentage of Participants Who Were Positive for Anti-Setrusumab Antibodies at Any Time During the Study up to Month 14

|
up to Month 14
|
|
Percentage of Participants With Adverse Events (AEs), Treatment-Emergent AEs (TEAEs), Serious TEAEs, and TEAEs Leading to Discontinuation or Death
Time Frame: Non-serious AEs: up to Month 14; Serious AEs: up to Month 24. (Average duration of exposure to placebo was 5 months and for setrusumab was 11 month plus follow-up to 24 months.)
|
An AE is any untoward medical occurrence, which does not necessarily have a causal relationship with treatment.
A serious AE (SAE) is defined as any untoward medical occurrence that, at any dose: results in death; is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent disability/incapacity; is a congenital anomaly/birth defect; is another important medical event.
The intensity for each AE was graded as mild, moderate or severe, according to the investigator's judgement.
An event was considered related to study drug if there were a "reasonable possibility" of a relationship, according to the investigator's clinical judgment.
A TEAE was defined as an event occurring or worsening on or after the first dose of study medication.
|
Non-serious AEs: up to Month 14; Serious AEs: up to Month 24. (Average duration of exposure to placebo was 5 months and for setrusumab was 11 month plus follow-up to 24 months.)
