Genisphere Reports Safety of 3DNA® Nanocarrier

HATFIELD, Pa., Nov. 15, 2017 /PRNewswire/ -- Genisphere LLC announced positive results from a non-GLP safety study evaluating dose escalation and repeated dose toxicity of the company's 3DNA nanocarrier in Sprague Dawley rats. The study demonstrated no adverse clinical findings after repeated intravenous administration of the maximum achievable dose of 3DNA nanocarrier. 

The study was conducted at Calvert Labs, Inc., a premier contract research organization that has been serving the biopharmaceutical community for 45 years. "Calvert is exceptionally pleased to have an opportunity to partner with the Genisphere team to help them advance their 3DNA platform forward," said Charles Spainhour, V.M.D., Ph.D., DABT, the Company's Chief Scientific Officer. "We look forward to continuing to help Genisphere design and execute IND enabling GLP safety studies that potentially advance one or more of their programs toward human clinical studies."

Dr. Vincent Meador, a globally recognized toxicologist and pathologist engaged by Genisphere, explained this study made meaningful progress in establishing the safety profile of the 3DNA nanocarrier. Dr. Meador said "Genisphere's licensing to biopharmaceutical partners has great potential to improve the efficacy and safety of life-saving therapeutics. This study makes great strides in demonstrating the inherent safety of 3DNA, and helps answer a crucial question from biopharmaceutical partners. Now the company is planning additional studies to further validate the safety of 3DNA technology."

Genisphere's Chief Science Officer, Bob Getts, explained this study was key to understanding the biopharmacological implications of 3DNA. He said, "We dosed as high as we were able in this study, orders of magnitude above the dose necessary to achieve efficacy, and have observed no repeat-dose toxicity. We suspect these positive results are driven by the innate biocompatibility of our DNA-based carrier. This finding is fundamental and establishes a solid foundation as we pursue our nanotechnology for targeted drug delivery, in our various programs and collaborations."
