- Secondary Outcome Measures
Name Time Method Mean Number of New Motor Milestones Achieved as Assessed by World Health Organization (WHO) Criteria MMDR Period: At Day 1800 The WHO motor milestones are a set of six milestones in motor development, all of which would be expected to be attained by 24 months of age in healthy children. The individual milestones are: sitting without support, standing with assistance, hands and knees crawling, walking with assistance, standing alone and walking alone. Mean of number of new milestones achieved was calculated and reported in this outcome measure.
Percentage of Participants With <2 Years of Age Who Attained Motor Milestones as Assessed by Section 2 of Hammersmith Infant Neurological Examination (HINE) At Day 309 HINE is evaluated in infants between 2-24 months of age. It's a simple, standardized instrument including 26 items assessing different aspects of neurological examinations, such as cranial nerves, posture, movements, tone, and reflexes. In this study, Module 2 of HINE (HINE-2) was assessed, which evaluates 8 developmental milestones (head control, sitting, voluntary grasp, ability to kick, rolling, crawling, standing, and walking) scored on a 3, 4, or 5-point scale, with 0 indicating inability to perform task and score of 2, 3, or 4 indicating full milestone development. Total score is calculated by summing item scores to give maximum possible score of 26. Higher score indicates good neurological function.
Number of Participants Who Died or Met Permanent Ventilation MMDR Period: Up to Day 1800 Permanent ventilation was defined as tracheostomy or \>=16 hours of ventilator support per day continuously for \>21 days in the absence of an acute reversible event.
Number of Participants Not Requiring Permanent Ventilation MMDR Period: Up to Day 1800 Permanent ventilation was defined as tracheostomy or \>=16 hours of ventilator support per day continuously for \>21 days in the absence of an acute reversible event.
Change From Baseline in Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND) Motor Function Scale Baseline, Day 2198 The CHOP INTEND test is designed to evaluate the motor skills of infants with significant motor weakness, including infants with SMA. Participants who are ≥2 years will be continued to be assessed until a CHOP INTEND maximum score of 64 is achieved. It includes 16 items structured to move from easiest to hardest with the grading including gravity eliminated (lower scores) to antigravity movements (higher scores). All item scores range from 0 (worst) to 4 (best). Total scores range from 0 to 64, with higher scores indicating better movement functioning.
Change From Baseline in Hammersmith Functional Motor Scale Expanded (HFMSE) Total Score MMDR Period: Baseline, MMDR Day 1800 The HFMSE consists of 33 scored activities used to assess motor function in children with SMA. Participants were asked to do a specific activity (such as rolling) and they were then graded on the quality and execution of that movement on a scale of 0=being unable, 1=performed with some compensation, and 2=unaided. The overall score is the sum of the scores for all activities with a maximum achievable score of 66. Higher scores indicate increased motor function.
Change From Baseline in Revised Upper Limb Module (RULM) Total Score MMDR Period: Baseline, MMDR Day 1800 RULM Test is used in participants with SMA to assess upper limb functional ability items and has total of 20 items with an entry item that serves as functional class identification and does not contribute to total score. Remaining 19 scorable items reflect different functional domains and graded on 3-point system with score of 0 (unable), 1 (able, with modification), and 2 (able, no difficulty). There is only 1 item that is scored as a can/cannot score, with 1 as the highest score. Scorable items are summed for total score (0-37), higher scores indicating increased upper limb function. Positive change from baseline indicates improvement.
Change From Baseline in Total Distance Walked Over Time as Assessed by 6-Minute Walk Test (6MWT) Baseline, Day 2670 The 6MWT measures the distance an individual can walk over a total of six minutes on a hard, flat surface. The goal is for the individual to walk as far as possible in six minutes.
Number of Participants Who Experienced Contracture Assesment MMDR Period: At MMDR Day 1800 Contracture assessment is performed to assess the motor performance in SMA. The number of participants who experienced at least one contracture at any location and severe contractures in any of the five locations (hip flexors, knee flexors, ankle planter flexors, elbow flexors, forearm flexors) are reported in this outcome measure.
Change From Baseline in Compound Muscular Action Potential (CMAP) MMDR Period: Baseline, MMDR Day 1800 CMAP is an electrophysiological technique that can be used to determine the approximate number of motor neurons in a muscle or group of muscles. Peroneal amplitude (PA) and ulnar amplitude (UA) data is reported in this OM. Score \<0 indicated worse response and \>0 indicated better response than the normal matched population. Score change \<0 indicated worsening and \>0 indicated improvement as compared to baseline.
Change From Baseline in Body Length MMDR Period: up to Day 1800 Participants were analyzed for change in growth parameter of body length to evaluate clinical efficacy. The body length was calculated using either WHO or Centers for Disease Control and Prevention (CDC) scales. The CDC scale allows to calculate the body length up to 20 years, while the WHO scale allows to calculate it only up to 10 years.
Change From Baseline in Weight MMDR Period: up to Day 1800 Participants were analyzed for change in growth parameter of weight to evaluate clinical efficacy. The weight was calculated using either WHO or CDC scales. The CDC scale allows to calculate the weight up to 20 years, while the WHO scale allows to calculate it only up to 10 years.
Change From Baseline in Weight for Age Percentile MMDR Period: up to Day 1800 Participants who were below the age of 36 months were analyzed for change in growth parameter of weight for age to evaluate clinical efficacy. The weight for age percentile was calculated using either WHO or CDC scales. The CDC scale allows to calculate the weight for age percentile up to 20 years, while the WHO scale allows to calculate it only up to 10 years.
Percentage of CMAP Responders MMDR Period: At Day 1800 CMAP is an electrophysiological technique that can be used to determine the approximate number of motor neurons in a muscle or group of muscles. A participant was defined as a responder if they had a peroneal amplitude ≥1 mV at last visit (including the amplitude ≥1 mV at baseline and also demonstrated as such at last visit).
Number of Participants Who Achieved Motor Milestones MMDR Period: up to Day 1800 Motor milestones were measured based on WHO criteria. The WHO motor milestones are a set of six milestones in motor development, all of which would be expected to be attained by 24 months of age in healthy children. The individual milestones are: sitting without support (SWS), standing with assistance (SWA), hands and knees crawling (HKC), and walking alone (WA).
Number of Participants Who Achieved Standing Alone and Walking With Assistance MMDR Period: up to Day 1800 Motor milestones were measured based on WHO criteria. The WHO motor milestones are a set of six milestones in motor development, all of which would be expected to be attained by 24 months of age in healthy children. The individual milestones are: SWS, SWA, HKC, WWA, WA and standing alone (SA). SA and WWA were assessed in this outcome measure.
Total Number of Hospitalizations Due to Serious Respiratory Events Up to day 2520 Total number of hospitalizations is total number of serious events that occurred during study for all participants under each group. For a participant with multiple SAEs which started at the same date and led to hospitalization, it is counted as one hospitalization.
Total Number of Hospitalizations Due to Serious Adverse Events Up to day 2520 Total number of hospitalizations is total number of serious events that occurred during study for all participants under each group. For a participant with multiple SAEs which started at the same date and led to hospitalization, it is counted as one hospitalization.
Percent of Time in Hospitalization Upto day 2160 Change From Baseline in Cobb-Angle on X-Ray of the Thoracolumbar Spine by Visit MMDR Period: Baseline, MMDR Day 1800 Cobb angle is a measurement of the degree of side-to-side spinal curvature used to define scoliosis.
Pediatric Quality of Life Inventory (PedsQL) Questionnaires Total Score by Domain MMDR Period: At Day 1800 Items on the PedsQL generic core scale are reverse scored and transformed to a 0-100 scale. The PedsQL parent (P) and self (S) reported questionnaire was collected for participants from 2 to 25 years of age. Four dimensions were collected: Physical, Emotional, Social and School functioning and each item was scored on a 5 point ordinal scale. 0 (never) =100, 1 (almost never) = 75, 2 (sometimes)= 50, 3 (often) = 25, 4 (almost always) = 0. A total score was calculated as the sum of all the items over the number of items answered on all the scales. If more than 50% of items or more were missing, the scale score was not computed. Higher scores indicated better health related quality of life.
Change From Baseline in Assessment of Caregiver Experience With Neuromuscular Disease (ACEND) Questionnaire Total Score MMDR Period: up to Day 1800 The ACEND is a questionnaire that includes a total of seven domains assessing physical impact (including feeding/grooming/dressing, sitting/play, transfers, and mobility) and general caregiver impact (including time, emotion, and finance) and each domain comprises several items. The total score (TS) for each domain will be calculated on a scale of 0 to 100. Higher scores indicate a greater impact on the caregiver.
Number of Participants With Disease-related Hospitalizations and AEs MMDR Period: up to Day 1800 Survival Rate MMDR Period: up to Day 1800 Survival rate was defined as the percentage of participants alive during the study and was estimated from the Kaplan Meier (KM) curve for time to death.
