Real-world use of vesemnogene lantuparvovec for spinal muscular atrophy in low- and middle-income countries

Real World Clinical Effectiveness & Safety of Vesemnogene Lantuparvovec for Spinal Muscular Atrophy (SMA) in Low-middle Income Countries (LMIC).

Phase 3 Interventional Lantu Biopharma · NCT07265232

This project sees if vesemnogene lantuparvovec is safe and helps improve motor skills and survival for people with genetically confirmed SMA who cannot access other curative treatments.

What this trial studies

This is an observational real-world registry following patients with genetically confirmed spinal muscular atrophy who receive vesemnogene lantuparvovec at a participating center. Eligible patients are screened for anti-AAV antibody levels, adequate liver function, and suitability for intrathecal administration before treatment. After administration, patients are monitored over time for developmental gross motor milestones, survival, laboratory values, and adverse events including predefined events of special interest. No subjects are actively withdrawn by the protocol, and follow-up reflects routine clinical visits and reporting.

Who should consider this trial

Good fit: Ideal candidates are people with genetically confirmed SMA who have low anti-AAV antibody titers (<1:20), acceptable liver tests, no contraindication to intrathecal procedures, and who are unable to access or have failed other curative SMA treatments.

Not a fit: Patients with high anti-AAV antibody levels, significant liver dysfunction, contraindications to intrathecal delivery, or those already doing well on available curative therapies are unlikely to benefit from this treatment pathway.

Why it matters

Potential benefit: If successful, the program could show that vesemnogene lantuparvovec improves motor development and survival and has an acceptable safety profile in real-world LMIC settings, supporting broader access.

How similar studies have performed: Related AAV-based SMN gene therapies have produced substantial improvements in motor milestones and survival in clinical trials and real-world use, but data specifically for vesemnogene lantuparvovec in LMIC populations are limited.
