Biogen to Present Data at AAN Highlighting Spinraza and Emerging Biomarkers for SMA

Biogen today announced it will present new data focusing on SMA at the 71st annual meeting of the American Academy of Neurology (AAN) in Philadelphia, PA., May 4–11.

Results from the NURTURE study demonstrate that pre-symptomatic infants with SMA treated with SPINRAZA over three years achieved motor milestones more consistent with normal childhood development. After three years of follow-up, interim results from the ENDEAR/CHERISH/SHINE open-label extension study show that treatment with SPINRAZA, particularly when initiated earlier, leads to progressive motor milestone improvements and increased survival rates for individuals with infantile-onset SMA. Additional data suggest that phosphorylated neurofilament heavy chain (pNF-H) may emerge as a promising biomarker to predict disease activity in SMA.

Cure SMA Provides Seed Funding for Spinraza

From 2003 to 2006, Cure SMA provided the very first research funding needed to begin investigation into the therapeutic approach behind SPINRAZA. We would like to thank and acknowledge Cold Spring Harbor Laboratory (CSHL) and the University of Massachusetts Medical School for generating critical intellectual property for the program that was licensed to Ionis Pharmaceuticals. We specifically thank Drs. Adrian Krainer, Yimin Hua and colleagues at CSHL for years of dedication to and hard work on the preclinical development of Spinraza for SMA, and Drs. Ravindra Singh and Elliot Androphy for their work funded by Cure SMA in originally identifying the ISSN1 gene sequence, which is the sequence targeted in Spinraza.
