- W2790507197 abstract "Objective: NURTURE (NCT02386553) is an ongoing phase 2, open-label, single-arm study, evaluating intrathecal nusinersen (12-mg equivalent dose) in infants with presymptomatic spinal muscular atrophy (SMA). Background: SMA is a neuromuscular disorder caused by a mutation in the survival motor neuron 1 ( SMN1 ) gene resulting in SMN protein deficiency. Nusinersen is an investigational antisense oligonucleotide drug that modifies SMN2 pre-mRNA splicing, promoting increased functional SMN protein production. Design/Methods: NURTURE is enrolling presymptomatic infants with genetically diagnosed SMA and evaluating their development from near birth to 2.5 years. The primary endpoint is time to death or respiratory intervention (tracheostomy/any ventilation support for ≥6 hours/day continuously for ≥7 days). Secondary endpoints include the proportion of infants developing clinical symptoms of SMA and achievement of motor milestones. Changes in compound muscle action potential (CMAP) and adverse events (AEs) also were assessed. Study enrollment started May 2015; interim results are reported. Results: As of 8 Jun 2016, 22 infants were screened; 17 were enrolled and dosed; 5 failed screening. Most (12/17) had 2 SMN2 copies, and most were aged ≤1 month at enrollment. All 17 infants remain enrolled; none have met the primary endpoints of respiratory intervention or death. Improvements in mean Hammersmith Infant Neurological Examination (HINE) motor milestones scores vs Baseline have been observed. Infants have generally gained weight over time consistent with normal development, and mean CMAP scores have mostly improved vs Baseline. There were no severe AEs reported, 5 infants experienced a serious AE. Three infants experienced AEs considered possibly related to study drug. No new safety concerns were identified. Conclusions: The NURTURE interim analysis shows that all the infants treated with nusinersen are alive and generally achieving new motor skills and appropriate age-related developmental gains. The efficacy and safety profile of nusinersen supports continued clinical development.
