Orally Delivered Compounds, Which Selectively Modify RNA Splicing Prevent Deficits In Mouse Models Of Spinal Muscular Atrophy
Date:8/7/2014

SOUTH PLAINFIELD, N.J., Aug. 7, 2014 /PRNewswire/ -- Today the journal Science published results of a preclinical study demonstrating that treatment with orally available RNA splicing modifiers of the SMN2 gene starting early after birth is preventing deficits in mouse models of Spinal Muscular Atrophy (SMA). Scientists from Roche Pharma Research and Early Development (pRED), PTC Therapeutics, Inc., the SMA Foundation, the University of Southern California and Harvard University collaborated to demonstrate that continuous treatment of SMA mice with these compounds increased life span, normalized body weight and prevented both disease-related motor dysfunction and neuromuscular deficits in a mouse model of SMA.

"The investigational compounds used in this study represent the first orally available SMN2 splicing modifiers for SMA," commented Stuart W. Peltz, CEO of PTC Therapeutics, Inc. "Using the experience and expertise in RNA biology we have gained at PTC over the last 16 years, we used our alternative splicing technology to identify and subsequently optimize investigational compounds that target the SMN2 splicing to produce the SMN protein. Our unique partnership with Roche and the SMA Foundation has allowed this project to rapidly move into clinical development."

"Although still preclinical, these results demonstrate how SMN2 splicing modifiers could correct the molecular deficit that causes SMA," said Luca Santarelli, Head of Neuroscience, Ophthalmology and Rare Diseases at Roche. "This study represents an important step towards developing a potential therapeutic option for this devastating and currently untreatable condition. Early clinical trials are currently underway to determine the safety and tolerability of this approach."
