Sangamo BioSciences Announces Results From Diabetic Neuropathy Clinical Trial SB-509-601

Date:11/10/2008

amination data, electrophysiological testing data, subject neurological questionnaire, and subject pain assessment. Specifically, investigators used the following tests: the visual analog scale for pain intensity (VASPI), a modified Neuropathy Impairment Score -- Lower Limbs (NIS-LL) scoring system as well as total neuropathy score (TNS) to assess signs and symptoms of the condition. In addition, data from electrophysiological testing using nerve conduction velocity (NCV) to assess the rate at which a nerve can conduct an electrical signal, and quantitative sensory testing (QST) with the Vibratron II instrument, to assess the threshold of detection of vibration were also collected. Skin biopsies were taken to evaluate the direct therapeutic effect of SB-509 on nerve regrowth.

About Diabetic Neuropathy

Diabetic peripheral neuropathy is one of the most frequent complications of diabetes. Symptoms include numbness, tingling sensations and pain particularly in the toes or feet. This gradually evolves to loss of sensation and motor function as nerve damage progresses. Ulcers and sores may appear on numb areas of the foot because pressure or injury goes unnoticed. Despite adequate treatment, these areas of trauma frequently become infected and this infection may spread to the bone, necessitating amputation of the leg or foot. More than 60 percent of non-traumatic lower-limb amputations in the United States occur among people with diabetes. In 2004, this translated to approximately 71,000 amputations. Diabetes is a growing problem, the Centers for Disease Control estimates that from 1980 through 2007, the number of Americans with diabetes increased from 5.6 million to 23.6 million and that of those about 60 percent to 70 percent have mild to severe forms of neuropathy.
