Interventions

OAV101
Gene therapy
Procedure
Sham control
The sham procedure will consist of a small needle prick on the lower back at the location where the LP injection is normally made. The needle will break the skin, but no needle insertion for lumbar puncture will occur.

Eligibility Criteria

Key Inclusion criteria:

Diagnostic confirmation during screening period of 5q SMA
The patient must be treatment naive (historical or current use) for all SMN-targeting therapies (e.g., risdiplam (Evrysdi) and nusinersen (Spinraza)).
Onset of clinical signs and symptoms at ≥ 6 months of age
A complete Hammersmith Functional Motor Scale - Expanded (HFMSE) assessment during the screening period for trial eligibility
Able to sit independently at screening, but has never had the ability to walk independently.

Key Exclusion criteria:

Anti-adeno-associated virus serotype 9 (AAV9) antibody titers > 1:50 at screening as determined by sponsor designated lab. NOTE: A negative anti-AAV9 antibody titer is defined as ≤ 1:50.
Infectious process (e.g. viral, bacterial) or febrile illness prior to start of screening, and up to OAV101 treatment or sham procedure
Hepatic dysfunction (i.e. alanine aminotransferase (ALT), total bilirubin, gamma-glutamyl transferase (GGT) or glutamate dehydrogenase (GLDH), > upper limit of normal (ULN).
Requiring invasive ventilation, awake noninvasive ventilation for > 6 hours during a 24-hour period, noninvasive ventilation for > 12 hours during a 24-hour period or requiring tracheostomy
Complications at screening that would interfere with motor efficacy assessments including but not limited to, severe contractures or Cobb angle > 40
Surgery for scoliosis or hip fixation in the 12 months prior to Screening or planned within the next 64 weeks
Clinically significant sensory abnormalities in the neurological examination at Screening
