Inclusion criteria

Inclusion criteria: STRENGTH Inclusion Criteria * Written informed consent * SMA diagnosis based on gene mutation analysis with bi-allelic SMN1 mutations and any copy of SMN2 gene * Aged 2

Exclusion criteria

Exclusion criteria: STRENGTH Exclusion Criteria * Excluding SMA, any medical condition considered clinically significant * Positive for human immunodeficiency virus (HIV), hepatitis B or hepatitis * Anti Adeno Associated Virus Serotype 9 (AAV9) antibody titer using an immunoassay is reported as elevated at Screening (reference to >1:50 or a validated result consistent with being elevated) * Clinically significant abnormalities in test results during screening period and/or at Baseline * Platelet count less than the lower limit of normal (LLN), or platelet transfusion within 1 month at Screening Visit 1 * Clinically significant abnormal coagulation panel results at Screening * Hepatic dysfunction (i.e. alanine aminotransferase (ALT), total bilirubin (TBL), gamma-glutamyl transferase (GGT) or glutamate dehydrogenase (GLDH) > upper limit of normal (ULN) at Screening (with the exception of isolated AST elevation: in the absence of other liver laboratory abnormalities, isolated elevated AST is not considered exclusionary) * Contraindications for lumbar puncture procedure * At Baseline (Day-1), participants are excluded if they received: * nusinersen (Spinraza®) within 4 months at Baseline * risdiplam (Evrysdi®) within 15 days at Baseline * Vaccinations 2 weeks prior to administration of OAV101 * Hospitalization for a pulmonary event, or for nutritional support within 2 months prior to Screening or inpatient major surgery planned. * Presence of the following: * An active infectious process requiring systemic antiviral or antimicrobial therapy up to 30 days prior to OAV101 administration, or * An active but untreated viral or bacterial infectious process up to 30 days prior to administration of OAV101, or * Any febrile illness up to 30 days prior to administration of OAV101 * 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, at Screening and up to OAV101 administration * Concomitant use of any of the following medication categories within 90 days prior to administration of OAV101 * Ongoing systemic immunosuppressive therapy (e.g., corticosteroids, cyclosporine, tacrolimus, methotrexate, cyclophosphamide, intravenous immunoglobulin, rituximab), plasmapheresis, immunomodulators (e.g., adalimumab) * History of hypersensitivity to any of the study treatments or its excipients or drugs of similar chemical classes

Design outcomes

Primary

MeasureTime frame
The primary objective of this study is to evaluate the performance of the Navigate Anti-AAV9 Antibody Assay using serum specimens in subjects with SMA in Novartis clinical studies COAV101B12301 *STEER* and COAV101B12302 *STRENGTH*. The primary measures of performance for the Navigate Assay are linked to the primary and secondary endpoints of Novartis clinical studies COAV101B12301 *STEER* and COAV101B12302 *STRENGTH*: STEER Primary Objective: EFFICACY: To compare the efficacy of OAV101 IT vs. sham control as measured by the change from baseline in HFMSE total score STRENGTH Primary Objective: To characterize the safety and tolerability of OAV101 IT over a 52-week period in patients with SMA aged 2 to 12 years who have discontinued treatment with nusinersen (Spinraza®) or risdiplam (Evrysdi®).
