A treatment-emergent Adverse Events (TEAE) is any Adverse Events that newly appeared, increased in frequency or worsened in severity following initiation of study drug administration. A severity grade was defined by the Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03. As per CTCAE, Grade 1 scales as Mild; Grade 2 scales as Moderate; Grade 3 scales as severe or medically significant but not immediately life threatening; Grade 4 scales as life-threatening consequences; and Grade 5 scales as death related to AE.
Safety Population includes all sentinel and randomized participants in the FAS who received at least one dose of vosoritide or placebo in this study.

Z-Scores were derived using age-sex specific reference data (means and SDS) for average stature children per the Centers for Disease Control and Prevention. A height Z score of 0 would indicate that the subject's height is equal to the mean height for the average stature population of the same sex and age. A positive height Z score indicates that the subjects height is above the mean height for the average stature population of the same sex and age, whilst a negative height Z score indicates that the subjects height is below the mean height for the average stature population of the same sex and age. To conclude if the height Z score increases then this means the height deficit has decreased.

The body mass index (BMI) Z-score represents the participant's BMI converted to an age and sex appropriate standard deviation score (SDS) by comparison with an average stature reference population. The weight Z-score of 0 represents the mean BMI for age and sex of the reference population. A positive BMI Z-score means BMI is above the mean BMI for the average stature population of the same sex and age and a negative BMI Z-Score means BMI is below the mean BMI for the average stature population of the same sex and age.
BMI Z-scores are derived only for participants aged 24 months or older, the change from baseline to Week 52 in BMI Z-score is summarized for Cohort 1 only as no participants in Cohort 2 or Cohort 3 were 24 months at baseline.

Change From Baseline in Functional Independence Measure for Children (WeeFIM-II) Score at Week 52
Query!
Assessment method [14]

0
The Pediatric Functional Independence Measure-II (WeeFIM®-II) is designed to measure functional independence of children between the ages of 6 months \& 18 yrs who have physical or general developmental limitations. The WeeFIM-II is comprised of 3 domains that are rated by clinicians based on information obtained from parents/caregivers (self-care \[score range 8 to 56\], mobility \[score range 8 to 35\], \& cognition \[score range 8 to 35\]) \& provides a total score between 18 (worst) \& 126 (Best). Higher score reflects higher level of independence.
Performance of a child on each of individual items within WeeFIM is assigned to one of seven levels on an ordinal scale that represent function from complete \& modified independence (levels 7 \& 6) without a helping person to modified \& complete dependence (levels 5 to 1) with a helping person.
Functional Independence Measure (Wee-FIM-II) is only validated in children ages 6 months to 18 yrs. Therefore results for Cohort 3 is not summarized.

BSID-III is performance-based clinician-reported outcome assessment for use in children from 1 to 42 months (1 month to 3.5 years). individually administered by the trained clinician to the participant/child
Scales include Cognitive subscale, Receptive and Expressive subscales, and Gross and Fine Motor subscales. The two language scales make up a composite Language Scale score and the Gross and Fine Motor subscales yield a composite Motor Scale score. In addition, there is a Social-Emotional Scale and Adaptive Behavior Scale, which is a questionnaire read and completed by parent or caregiver. Scores range from 0 to 2, and indicate mastery (2), emerging (1) or zero (not present)
Each (sub)scale yields a total raw score, standardized according to the participant's chronological age (scaled scores)

Change From Baseline in Child Behaviour Checklist (CBCL) at Week 52
Query!
Assessment method [16]
0
0
The CBCL is used as a screening tool for emotional or behavioral problems, measuring initial behavior severity, tracking changes in behavioral problems over the course of treatment, and treatment planning. The CBCL 1.5-5 years old consists of 100 questions, scored on a three-point Likert scale (0=Not True (as far as you know), 1= Somewhat or Sometimes True, 2=Very True or Often True). The scores for each individual question within a domain are summed to give a domain score. The CBCL uses a normative sample to create standard scores, which are scaled so that 50 is average with a standard deviation of 10, where higher scores indicate more emotional or behavioral issues.
CBCL was waived for children \< 18 months old. Therefore results for Cohort 3 is not summarized.

Hologic - Discovery Horizon Whole Body BMD Z-Score.
Change in whole body bone mineral density (BMD) Z-score from baseline at 52 weeks indicates whether there has been a positive or negative change in BMD using a z-score generated by converting the participants BMD to an age and sex appropriate standard deviation score (SDS) by comparison with an average stature reference population. A whole body BMD Z-score \<-2 SD can indicate low bone density in children. The Whole Body BMD (bone mineral density) z-score compares the BMD to the average bone density of people of the same age, and sex as a comparator. A Z-score less than 0 means that the participant has a lower BMD than people in the same age and sex group, and could indicate a risk of osteopenia or osteoporosis.

AHI is a marker of obstructive sleep apnea (OSA), scored as No.of apnea or hypopnea epi/hr, with AHI \<=1/hr normal, 1\< AHI\<=5 mild,5\< AHI \<=10 moderate,\& AHI\>10/hr severe OSA. CAI reflects cervical cord compression at cervical-medullary junction, \& is No. of epi of a pause in ventilation with no associated respiratory effort, with\> 5 epi/hr abnormal.O2 desaturation index measures average No. of desaturation epi/hr, defined as decrease in O2 saturation of \>=3% for at least 10sec, with(\<8/hr normal \& \>=8/hr abnormal
