ANAVEX 1066

anavex-1066

Anavex has reported preclinical efficacy for the treatment of neuropathic pain and visceral pain with ANAVEX 1066.

ANAVEX 1066 was tested in two models of neuropathic and visceral pain that have been extensively validated in rats.  In the chronic constriction injury (CCI) model of neuropathic pain, a single oral administration of ANAVEX 1066 dose-dependently restored the nociceptive threshold in the affected paw to normal levels while leaving the contralateral healthy paw unchanged. Efficacy was rapid and remained significant for two hours. In a model of visceral pain, chronic colonic hypersensitivity was induced by injection of an inflammatory agent directly into the colon and a single oral administration of ANAVEX 1066 returned the nociceptive threshold to control levels in a dose-dependent manner. Companion studies in rats demonstrated the lack of any effects on normal gastrointestinal transit with ANAVEX 1066 and a favorable safety profile in a battery of behavioral measures.
