Research summary
The purpose of this study is to see whether ISIS 396443 (the study drug) has any effects (good or bad), when it is given over a longer period of time to children with Spinal Muscular Atrophy (SMA) who previously completed an ISIS 396443 research study.
ISIS 396443 is not approved for marketing or use. It is approved for clinical research, and thus its safety or efficacy has not been determined yet.
The symptoms of Spinal Muscular Atrophy (SMA) occur when Survival motor neuron (SMN) protein is missing in the nerves of the spinal cord and the brain. In animal studies, the drug ISIS 396443 was shown to increase the amount of Survival motor neuron (SMN) protein in the spinal cord and brain, and there were positive effects in the animals’ movements and how long they lived.
ISIS 396443 has been studied in animals and as of 6 February 2014 has been given to 65 patients with Spinal Muscular Atrophy (SMA) as single and multiple doses. At this time, the possible effects of the drug, good and bad are unknown.
This study will be performed at research sites around the whole world. Up to 228 children around the world may take part in this study.REC name
