Number of Participants With Treatment Emergent Adverse Events (TEAEs) by Type and Severity
Query!
Assessment method [1]
0
0
An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. TEAEs were defined as all AEs that occurred at or after the first dose of the investigational product or device implant surgery (whichever occurred earlier) and through the last follow-up date. Drug-related and device-related types of TEAEs were analyzed and reported. The severity of AEs was assessed by the investigator using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) Version 4.0 grading scale. Severity of all AEs or SAEs was recorded as grade 1, 2, 3, 4, or 5 corresponding, respectively, to a severity of mild, moderate, severe, life-threatening, or fatal. Here SDI refers to surgical device implantation.

Change From Baseline in Motor Function Using Gross Motor Function Measure 88 (GMFM-88) Total Score at Week 40
Query!
Assessment method [1]

The GMFM-88 was used to measure motor function. The GMFM-88 item scores were used to calculate domain-specific percent score for each of the 5 GMFM-88 dimensions (lying and rolling; sitting; crawling and kneeling; standing; walking, running, and jumping), and a total GMFM-88 (percent) score was calculated based on each dimension score. Each of the 88 items was rated on a 4-point scale: 0=does not initiate; 1=initiates; 2=partially completes; and 3=completes. The GMFM-88 total scores ranged from 0% (no mobility) to a score of 100%, that is (i.e,) the score that can be obtained by an average 5-year-old or older child with normal motor abilities.

Change From Baseline in Adaptive Behavior Composite Standard Score as Measured by Vineland Adaptive Behavior Scales, Second Edition (VABS-II) at Week 40
Query!
Assessment method [10]

The VABS-II test measures adaptive behaviors, including the ability to cope with environmental changes, to learn new everyday skills, and to demonstrate independence. This test measures the following 4 key domains: communication, daily living skills, socialization, motor skills, and the adaptive behavior composite (ABC) (a composite of the other 4 domain). Items in each domain are rated as either 0 (does not), 1(sometimes) or 2(independently) performs a given behavior or skill. The 4 domain standard scores range from 20-160 and higher scores indicate a higher level of functioning. ABC scores have a mean of 100 and a standard deviation of 15 (range = 20 to 160) and higher scores indicate a higher level of functioning. A positive change value indicates improvement in adaptive functioning.
