Primary

MeasureTime frameDescription
Time to Death or Respiratory InterventionScreening up to Day 2891The time was the age of the participant at the first occurrence of either a respiratory intervention or death. Respiratory intervention was defined as invasive or noninvasive ventilation for ≥6 hours/day continuously for 7 or more days OR tracheostomy.

Secondary

MeasureTime frameDescription
Percentage of Participants AliveUp to 8 years of age
Change From Baseline in Weight for LengthBaseline, Day 1849The WHO child growth standards for participants aged up to 10 years was used to determine the percentiles. WHO Anthro software was used to calculate the percentiles for the given weights of each child.
Change From Baseline in Head CircumferenceBaseline, Day 2891
Change From Baseline in Chest CircumferenceBaseline, Day 2891
Percentage of Participants Who Attained Motor Milestones Assessed as Part of the Hammersmith Infant Neurological Examination (HINE)Day 700HINE 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.
Percentage of Participants Who Attained Motor Milestones as Assessed by World Health Organization (WHO) CriteriaBaseline up to Day 2891The 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.
Change From Baseline in the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND) Motor Function ScaleBaseline, Day 2891The CHOP-INTEND test was designed to evaluate the motor skills of infants with significant motor weakness. Participants who were ≥2 years were continued to be assessed until a CHOP INTEND maximum score of 64 was achieved. It included 16 items (capturing neck, trunk, and proximal and distal limb strength), nine of which were scored 0, 1, 2, 3, or 4, five were scored as 0, 2, or 4, one was scored as 0, 1, 2, or 4, and one as 0, 2, 3, or 4 with higher scores indicating greater muscle strength and function. Total score was calculated as the sum of scores for each item. Total score ranged from 0 (worst possible score) and 64 (best possible score). CHOP-INTEND assessments were discontinued once participants achieved a maximum score of 64, so the number of participants with available data points decreased over time.
Change From Baseline in Hammersmith Functional Motor Scale - Expanded (HFMSE)Baseline, Day 2160The 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 and ranged from 0 to 66. Higher scores indicate increased motor function. Baseline was defined as the time of first HFMSE score after Day 700.
Change From Baseline in Weight for AgeBaseline, Day 2891The World Health Organization (WHO) child growth standards for participants aged up to 10 years was used to determine the percentiles. WHO Anthro software was used to calculate the percentiles for the given weights of each child. Negative change from baseline indicates low weight for age percentile.
Change From Baseline in Head to Chest Circumference RatioBaseline, Day 2891Negative change from baseline indicates reduction in head-to-chest circumference ratio.
Change From Baseline in Arm CircumferenceBaseline, Day 2891
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)From the signing of the informed consent form (ICF) up to the end of the study (up to Day 2891)AE was any unfavorable and unintended sign (including an abnormal assessment such as an abnormal laboratory value), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An SAE was any untoward medical occurrence that at any dose resulted in death, in the view of the Investigator, placed the participant at immediate risk of death, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, resulted in a birth defect.
Number of Participants With Shifts From Baseline in Clinical Laboratory Parameters (Hematology Parameters)Baseline up to Day 2891Hematology parameters included hemoglobin, hematocrit, erythrocytes, platelets, leukocytes, neutrophils, eosinophils, basophils, lymphocytes, and monocytes count. These parameters were flagged as low, normal, or high relative to parameter's normal range or as unknown if no result was available. Here, shift to low indicated values that were normal, high or unknown at baseline and shifted to low values postbaseline. Shift to high indicates values that were normal, low or unknown at baseline and shifted to high postbaseline values.
Proportion of Participants Developing Clinically Manifested Spinal Muscular Atrophy (SMA)At 13 and 24 months of ageA participant was considered having clinically manifested SMA if any of the following occurred: * Age-adjusted weight \<5th percentile or decrease of ≥2 major weight growth curve percentiles (3rd, 5th, 10th, 25th, or 50th) or a percutaneous gastric tube placement for nutritional support * Failure to achieve the ability to sit without support * Failure to achieve standing with assistance * Failure to achieve hands-and-knees crawling * Failure to achieve walking with assistance by 24 months of age * Failure to achieve standing alone by 24 months of age * Failure to achieve walking alone by 24 months of age
Number of Participants With Shifts From Baseline in Clinical Laboratory Parameters (Urinalysis Parameters)Baseline up to Day 2891Urinalysis included assessments of specific gravity, pH, protein, glucose, ketones, bilirubin, occult blood, erythrocytes, leukocytes, epithelial cells, bacteria, casts and crystals. These parameters were flagged as low, normal, or high relative to parameter's normal range or as unknown if no result was available. Here, shift to low indicated values that were normal, high or unknown at baseline and shifted to low values postbaseline. Shift to high indicates values that were normal, low or unknown at baseline and shifted to high postbaseline values.
Number of Participants With Shifts From Baseline in Coagulation Parameters [Activated Partial Thromboplastin Time (aPTT)]Baseline up to Day 2891aPTT was evaluated to assess safety. Shift to high measured change in normal, low and unknown values at baseline to high values postbaseline.
Number of Participants With Shifts From Baseline in Coagulation Parameters [Prothrombin Time (PT)]Baseline up to Day 2891PT was evaluated to assess safety. Shift to high measured change in normal, low and unknown values at baseline to high values postbaseline.
Number of Participants With Shifts From Baseline in Coagulation Parameters [International Normalized Ratio (INR)]Baseline up to Day 2891INR was evaluated to assess safety. Shift to high measured change in normal, low and unknown values at baseline to high values postbaseline.

Change From Baseline in Hammersmith Functional Motor Scale - Expanded (HFMSE)

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 and ranged from 0 to 66. Higher scores indicate increased motor function. Baseline was defined as the time of first HFMSE score after Day 700.

Change From Baseline in the Children's Hospital of Philadelphia Infant Test of Neuromuscular Disorders (CHOP INTEND) Motor Function Scale

The CHOP-INTEND test was designed to evaluate the motor skills of infants with significant motor weakness. Participants who were ≥2 years were continued to be assessed until a CHOP INTEND maximum score of 64 was achieved. It included 16 items (capturing neck, trunk, and proximal and distal limb strength), nine of which were scored 0, 1, 2, 3, or 4, five were scored as 0, 2, or 4, one was scored as 0, 1, 2, or 4, and one as 0, 2, 3, or 4 with higher scores indicating greater muscle strength and function. Total score was calculated as the sum of scores for each item. Total score ranged from 0 (worst possible score) and 64 (best possible score). CHOP-INTEND assessments were discontinued once participants achieved a maximum score of 64, so the number of participants with available data points decreased over time.

Percentage of Participants Who Attained Motor Milestones Assessed as Part of the Hammersmith Infant Neurological Examination (HINE)

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.
