( reversible. We are pleased that our ...)Sangamo BioSciences Announces Presentation of Phase 1 ZFP,Therapeutic Data at American Diabetes Association Meeting,Health

"We are pleased that our SB-509 diabetic neuropathy program Phase 1 update was selected for an oral presentation at the most significant US diabetes meeting of the year," said Edward Lanphier, Sangamo's president and CEO. "We believe that SB-509 represents a new therapeutic approach for diabetic neuropathy, designed to directly protect and possibly restore nerve function, in contrast to the current standard of care designed to address the pain associated with this condition. We expect to provide an additional update on the progress of this trial later in the year. We are encouraged by the data so far and are swiftly moving forward to the next stage of clinical development with our two ongoing Phase 2 clinical trials."

About the SB-509 Clinical Program

SB-509 is an injectable formulation of plasmid DNA that encodes a ZFP TF, designed to upregulate the VEGF-A gene.

Phase 1

Phase 1b study to assess the safety and clinical effects of a single administration of SB-509 to subjects is ongoing. Subjects were randomized and administered either SB-509 or placebo in both legs by intramuscular injection. Two dose levels of SB-509 have been tested. At the first dose level, three subjects were administered placebo and three subjects were treated with a total of 30 mg of SB-509, 15 mg per leg. Accrual of these subjects is complete. A further twenty-two subjects have been treated at the second dose level with either placebo or a total dose of 60 mg of SB-509, administered as 30 mg per leg. Subjects in this Phase 1b study will be monitored for both the safety and tolerability of SB-509 treatment as well as evaluation of pain and clinical effects on lower limb diabetic neuropathy at one, two, three and six months post-treatment.

Phase 2

Sangamo has two ongoing Phase 2 studies in diabetics with sensory/motor neuropathy:
