An Open Label Study of Gene Therapy Product (Vesemnogene Lantuparvovec) in Spinal Muscular Atrophy
Lantu Biopharma tarafından yürütülen bu açık etiketli (open label) Faz 1/2 (Phase 1/2) çalışması, spinal musküler atrofi (spinal muscular atrophy, SMA) hastalarında vesemnogene lantuparvovec (AAV-hSMN1) adlı gen tedavisinin güvenliliğini ve etkililiğini değerlendirmektedir. Çalışmaya, SMN1 (survival motor neuron) geninde iki alelli (bi-allelic) mutasyon (delesyon veya nokta mutasyonu) saptanarak gen mutasyon analiziyle SMA tanısı konmuş hastalar alınmaktadır; hastanın veya ebeveyn/yasal vasisinin bilgilendirilmiş onam sürecini tamamlaması ve çalışma prosedürlerine uyabilmesi gerekmektedir. Çalışma aktif durumdadır ancak yeni katılımcı almamaktadır.

Inclusion Criteria: * Diagnosis of SMA based on gene mutation analysis with bi-allelic survival motor neuron (SMN1) mutations (deletion or point mutations). * Patients or Parent(s)/legal guardian(s) willing and able to complete the informed consent process and comply with study procedures and visit schedule. Exclusion Criteria: * Anti-AAV9 antibody titers \>1:20 as determined by Enzyme-linked Immunosorbent Assay (ELISA) binding immunoassay. * Active viral infection (includes HIV or serology positive for hepatitis B or C). * Use of invasive ventilatory support (tracheotomy with positive pressure) or pulse oximetry \<95% saturation. * Concomitant illness and any drug that in the opinion of the investigator creates unnecessary risks for gene transfer. * Clinically significant abnormal laboratory values. * Participation in a recent SMA treatment clinical trial that in the opinion of the PI creates unnecessary risks for gene transfer. * Patient with signs of aspiration based on a swallowing test and unwilling to use an alternative method to oral feeding. * For children ≥ 24 months of age, contraindications for spinal tap procedure or administration of intrathecal therapy or presence of an implanted shunt for the drainage of CSF or an implanted central venous (CNS) catheter. * For children ≥ 24 months of age, severe contractures as determined by Physical Therapist(s) at screening that interfere with either the ability to attain/demonstrate functional measures or interferes with ability to receive dosing. * For children ≥ 24 months of age, severe scoliosis (defined as ≥ 50° curvature of spine) evident on X-ray examination. * For children ≥ 24 months of age, previous, planned or expected scoliosis repair surgery/procedure within 1 year of dose administration.
