Patent 7,838,657 protects SPINRAZA and is included in one NDA.

Summary for Patent: 7,838,657
Title:Spinal muscular atrophy (SMA) treatment via targeting of SMN2 splice site inhibitory sequences
Abstract: The present invention is directed to methods and compositions capable of blocking the inhibitory effect of a newly-identified intronic inhibitory sequence element, named ISS-N1 (for "intronic splicing silencer"), located in the SMN2 gene. The compositions and methods of the instant invention include oligonucleotide reagents (e.g., oligoribonucleotides) that effectively target the SMN2 ISS-N1 site in the SMN2 pre-mRNA, thereby modulating the splicing of SMN2 pre-mRNA to include exon 7 in the processed transcript. The ISS-N1 blocking agents of the invention cause elevated expression of SMN protein, thus compensating for the loss of SMN protein expression commonly observed in subjects with spinal muscular atrophy (SMA).
