Clinical trial Recruiting at 6 sites Phase 4 Interventional Ages 2 to 100

Spinal muscular atrophy patients get a single intrathecal gene therapy dose to see how it works in real-world U.S. settings

Official title: Onasemnogene Abeparvovec: ASsessing The REAl-world Safety & Effectiveness of Spinal Muscular Atrophy Participants Treated With Intrathecal Onasemnogene Abeparvovec-brve (ITVISMA®): A U.S. Pragmatic Multicenter Study (STREAM)

Run by Novartis · NCT07448610 · Data updated 2026-11-12

This study tests whether a one-time intrathecal dose of ITVISMA® (onasemnogene abeparvovec-brve) is safe and effective for SMA patients in real-world U.S. clinical practice.

Is this trial a fit for you?

Likely a good fit

Genetically confirmed SMA patients aged 2 years and older who are planned to receive a single intrathecal ITVISMA® dose in routine U.S. care and have at least 1 year of pre-treatment medical history in the site records.

Probably not a fit

Patients who do not receive the intrathecal ITVISMA® dose or lack sufficient pre-treatment history may not contribute to the primary analyses.

What this trial studies

STREAM is a prospective, multicenter, non-randomized cohort study in the United States assessing a single intrathecal dose of ITVISMA® in genetically confirmed SMA patients. Participants are followed in routine care, with each patient serving as their own baseline and an external matched retrospective cohort used for context. Pre-specified endpoints, standardized motor-function assessments, and a detailed analysis plan are used to describe safety and functional outcomes while addressing missing data and intercurrent events. The study emphasizes pragmatic collection of real-world evidence without randomization or placebo control. Enrollment targets SMA patients aged 2 years and older who are treated in standard clinical practice.

Why it matters

Potential benefit: Findings could clarify real-world safety and effectiveness of ITVISMA® for SMA and inform clinical decision-making.

How similar studies have gone: Previous intrathecal or gene-therapy real-world studies in SMA and similar conditions have shown the value of pragmatic designs, though this exact approach is relatively novel for ITVISMA® in the U.S.

Show full inclusion / exclusion criteria
Key Inclusion Criteria:

A participant will be enrolled in STREAM only if all the following conditions are met:

* The participant has a genetically confirmed diagnosis of SMA (biallelic SMN1 deletion or mutation).
* He or she is ≥ 2 years of age on the day of the intrathecal injection.
* The treating Investigator intends to administer within the current episode of care, a single dose of ITVISMA® (1.2 × 10¹⁴ vg) in routine U.S. practice after written informed consent obtained.
* One of the following functional categories applies at screening:

  1. independently ambulatory child/adolescent 2 - \<18 years; or
  2. independently ambulatory adult (≥ 18 years).
  3. non-ambulatory (includes walkers with assistance) adult \> 18 years with entry level RULM at baseline
* At least 1 year of pre-treatment medical history, including motor-function documentation, can be retrieved from the site electronic record.

Key Exclusion Criteria:

A participant will be excluded if any of the following conditions apply:

* Contraindication for lumbar puncture as determined by the investigator (e.g., spinal anatomy that precludes safe lumbar puncture)
* An uncontrolled acute illness, active infection, febrile illness or acute medical condition, within 30 days prior to dosing
* Inability to tolerate corticosteroids administered by mouth or gastrostomy tube
* Current participation in another interventional clinical trial that would interfere with the objectives or endpoints of STREAM. Note: participation in observational cohort studies or non-interventional studies in which the participant does not receive treatment or undergo procedures which may compromise this study data integrity may be allowed following Sponsor approval
* Planned relocation or any circumstance that is likely to prevent completion of the minimum 12-month follow-up.

Other protocol inclusion, exclusion criteria may apply.
