Isis Pharmaceuticals, Inc. (NASDAQ: ISIS) announced today that it has earned a $2.15 million milestone payment from Biogen related to advancing the ongoing pivotal Phase 3 study (CHERISH) evaluating ISIS-SMNRx in children with spinal muscular atrophy (SMA). To date, Isis has generated more than $120 million in payments from Biogen related to the development of ISIS-SMNRx.
