Isis Initiates Phase 1 Clinical Study of ISIS-SMNRx in Patients With Spinal Muscular Atrophy
Press Release | December 19, 2011
CARLSBAD, Calif., Dec. 19, 2011 /PRNewswire/ — Isis Pharmaceuticals, Inc. (NASDAQ: ISIS) announced today that it has initiated a Phase 1 study of ISIS-SMNRx in patients with spinal muscular atrophy (SMA). SMA is a severe motor-neuron disease that is the leading genetic cause of infant mortality. Isis is developing ISIS-SMNRx as a potential treatment for all Types of SMA.
“SMA is a devastating disease that leads to the loss of motor neurons resulting in muscle weakness and respiratory failure in children. The genetic cause of this disease is well understood, but there are currently no effective disease-modifying therapies. Currently, treatment of SMA is entirely symptomatic and focuses on preserving muscle strength and lung function by physical therapy and assisted ventilation. This supportive approach has improved the natural history of SMA by extending life expectancy, but muscle weakness and atrophy are not affected. A disease-modifying drug like ISIS-SMNRx that specifically targets the cause of the disease could, for the first time, restore muscle strength and respiratory function and dramatically improve the children’s function and quality of life,” said Darryl C. De Vivo, M.D., Sidney Carter Professor of Neurology and Pediatrics and Co-Director of the Motor Neuron Center at Columbia University Medical Center.
