Brief Summary

This is a long-term follow-up safety and efficacy study of participants in clinical trials for spinal muscular atrophy (SMA) who were treated with onasemnogene abeparvovec-xioi. Participants will roll over from their respective previous (parent) study into this long-term study for continuous monitoring of safety as well as monitoring of continued efficacy and durability of response to onasemnogene abeparvovec-xioi treatment.

Primary Outcome Measures
NameTimeMethod
Number of Participants Who Experience a Clinically Significant Change From Baseline in Clinical Laboratory AssessmentsUp to 5 years

Blood samples will be collected for hematology (including complete blood cell count) and chemistry.

Change From Baseline in Height MeasurementsUp to 5 years
Number of Participants Who Experience a Clinically Significant Change From Baseline in Pulmonary Assessment Results and Require Ventilatory SupportUp to 15 years

Participants will receive pulmonary assessments by a pulmonologist or appropriate clinician. Respiratory device data will be reviewed for participants receiving non-invasive ventilatory support.

Number of Participants Who Experience a Clinically Significant Change From Baseline in Cardiac AssessmentsUp to 5 years

Cardiac assessments will include a 12-lead electrocardiogram, transthoracic echocardiogram and Troponin-I.

Number of Participants Who Reach Developmental MilestonesUp to 5 years

Assessed via the developmental milestone checklist, formed of 10 yes/no questions. The developmental milestones are: head control, sitting with support, sitting without support, sitting without support for 30 seconds, hands-and-knees crawling, pulls to stand, standing with assistance, walking with assistance, standing alone and walking alone.

Number of Participants Who Experience Swallowing Dysfunction and Require Nutritional SupportUp to 5 years

Assessed via the swallowing function questionnaire, formed of 4 yes/ no questions and 1 body weight question.

Number of Participants Who Experience a Clinically Significant Change From Baseline in Vital Signs MeasurementsUp to 5 years

Vital sign measurements will include blood pressure, respiratory rate, pulse, axillary temperature, and pulse oximetry.

Change From Baseline in Weight MeasurementsUp to 5 years
Number of Participants Who Experience at Least One Adverse Event of Special Interest (AESI)Up to 15 years

An AESI is defined as an AE occurring during any study phase that fulfills one of the following criteria:

* Hepatotoxicity

* Thrombotic microangiopathy

* Cardiac adverse events

* Dorsal root ganglia toxicity

* New malignancies

* New incidence of a neurologic disorder

* New incidence of an autoimmune disorder

* New incidence of hematologic disorder

Change From Baseline in Bayley Scales of Infant and Toddler DevelopmentUp to 42 months, 15 days of age

Third Edition (Bayley-III) to be performed in all patients up to 42 months, 15 days of age.

Change From Baseline in Revised Upper Limb Module (RULM) ScoreUp to 5 years

RULM score is based on a scale from 0 to 37 where lower scores reflect poorer upper limb functional ability.

Change From Baseline in Assessment of Caregiver Experience With Neuromuscular Disease (ACEND)Up to 5 years

ACEND score is based on a scale from 1 to 41 where higher scores represent a better caregiver experience

Number of Participants With Other SMA Therapies Overall and by Type of MedicationsYear 6 to Year 15
Change From Baseline in Hammersmith Functional Motor Scale - Expanded (HFMSE) ScoreUp to 5 years

The HFMSE was devised for use in children with SMA to give objective information on motor ability and clinical progression. The HFMSE is formed of 33 assessments rated from 0 (unable to perform functional task) to 2 (able to perform functional task unassisted). Higher scores on the total scale of 0-66 indicates higher levels of motor ability.

Number of Participants Who Experience a Clinically Significant Change from Baseline in Physical Examination FindingsUp to 5 years

The physical examination includes review of the following systems: head, ears, eyes, nose and throat, lungs/thorax, cardiovascular, abdomen, musculoskeletal, neurologic, dermatologic, lymphatic, and genitourinary. In addition, visual inspection of the spine, back, shoulders, and hips looking for spinal curvature and asymmetry will be carried out. Joints will be assessed for loss of mobility and contractures.

Number of Participants Who Experience a Clinically Significant Change From Baseline in Observational Phase Questionnaire ResultsYear 6 to Year 15

The observational phase questionnaire includes 7 yes/no questions. Observation categories include: adverse events, hospitalizations, concomitant medications, ventilatory support and feeding support.

Change From Baseline in Clinical Evaluation of Language Fundamentals Fifth Edition (CELF-5) Performed in All Participants 5 to 21 Years of AgeUp to 5 years

The CELF-5 Following Directions and Sentence Repetition subtests use scoring that varies based on age, but will be administered to participants 5-21 years of age. The Following Directions subtest will be scored from 0-33 with higher score being more advanced and the Recalling Sentences subtest will be scored from 0-78 with higher score being more advanced.

Number of Participants With Concomitant Medications Overall and by Type of MedicationsUp to 5 years
Number of Participants Who Experience at Least One Serious Adverse Event (SAE)Up to 15 years

An SAE is defined as any adverse event (appearance of \[or worsening of any pre existing\]) undesirable sign(s), symptom(s), or medical conditions(s) which meets any one of the following criteria:

* Fatal

* Life-threatening

* Results in persistent or significant disability/incapacity

* Constitutes a congenital abnormality or birth defect

* Requires in-patient hospitalization or prolongation of existing hospitalization

* Is medically significant e.g. defined as an event that jeopardizes the participant or may require medical or surgical intervention to prevent one of the outcomes listed above

Change From Baseline in Cogstate Computerized Cognitive Battery Performed in Age 48 Months and OlderUp to 5 years

The Cogstate Computerized Cognitive Battery consists of the Identification Test (scored 0 (best) to 1.5708 (worst)), the International Shopping List Test (scored 0 (worst) to 999 (best)), the International Shopping List Test-Delayed Recall (scored 0 (worst) to 999 (best)), the One Card Learning Test (scored 0 (worst) to 1.5708 (best)), and the One Back Test (scored 0 (worst) to 1.5708 (best)).
