Impact Of Intrathecal Administration Of INS1202 AAV9-SOD1-ShRNA Gene Therapy On Hallmarks Of Neurodegeneration In A Murine Disease Model Of ALS And A Patient-Derived In Vitro Model (ENCALS 2026) - "INS1202 was well tolerated. In vitro, INS1202 treatment of ALS donor-derived astrocytes resulted in MN rescue in co-cultures with SOD1-ALS astrocytes and in 7 of 10 sALS astrocyte lines.Conclusion INS1202 improved survival, motor function and ameliorated hallmarks of neurodegeneration in SOD1-G93A mice, was well tolerated in NHPs, and showed potential for treating people with SOD1-ALS and sALS."

Impact of intrathecal delivery of INS1202 AAV9-SOD1-shRNA on hallmarks of neurodegeneration in a murine disease model of ALS and patient-derived in vitro models (ALS-MND 2025) - "SOD1G93A mice treated with INS1202 (n¼ 7–12/sex/ group) (1) showed widespread biodistribution of INS1202 DNA(2) showed a 70% improvement in median survival (p<0.0001; median age of death 220 days) compared to vehicle-treated mice, (3) gained and sustained physiological weight (p<0.0001),(4) retained muscle function measured via the rotarod test (p<0.0001), and muscle force measured with the muscle physiology Aurora system (p<0.0001). Additionally, compared to vehicle-treated, SOD1G93A mice treated with INS1202 exhibited significantly lower plasma neurofilament levels presymptomatically (p50,p<0.01,n¼ 6/group), at p110 ± 10, when vehicle-treated mice show signs of paralysis (p<0.0001,n¼ 4–6/ group) and at p200 ± 5, which was the established end of study. INS1202 treatment of SOD1G93A mice resulted in rescue of lumbar MN numbers (n¼ 2/sex/group,p¼ 0.024), and glia marker staining intensity to levels observed in wildtype..."
