AstraZeneca developed disufenton (NXY-059), a free radical trapping agent, for the treatment of ischaemic stroke and other brain injuries. Nevertheless, large clinical trial (3306 versus 1722 patients) was neutral, providing no evidence for the efficacy of disufenton sodium in patients with stroke. One study using rat cortical brain slices concluded that NXY-059 improved neuronal survival. However, another study in mouse neuroblastoma cells reported no effect. Another study reported that NXY-059 restored endothelial blood-brain. Histological analyses revealed several therapeutic advantages associated with disufenton sodium treatment following acute acoustic trauma, including reductions in inner and outer hair cell loss; reductions in acute acoustic trauma-induced loss of calretinin-positive afferent nerve fibers in the spiral lamina; and reductions in fibrocyte loss within the spiral ligament. However, AstraZeneca terminated the development program.
