About SBS Plant-Produced Insulin

SemBioSys’ plant-produced insulin is human insulin produced from genetically enhanced safflower. SemBioSys has demonstrated that its plant-produced insulin is physically, structurally and functionally indistinguishable from pharmaceutical-grade human insulin through analytical testing and pre-clinical sub-chronic toxicology studies in rodents and primates. SemBioSys is currently conducting a Phase I/II clinical trial of its plant-produced insulin. The three-arm study, of up to 30 healthy volunteers, is designed to demonstrate the bioequivalence of safflower-produced insulin to two commercial insulin standards. Full results are expected to be available during the first half of 2009.
