LOUISVILLE, CO--(Marketwired - June 08, 2015) -
("AntriaBio" or the "Company") (OTCQB: ANTB), a biopharmaceutical corporation developing novel extended release therapies, released preclinical results for its lead product candidate, AB101, at the American Diabetes Association 75th
in Boston. The results demonstrated that AB101 has comparable in vitro pharmacology to native insulin, and in two animal species exhibited a prolonged subcutaneous insulin absorption profile, resulting in slow onset, peakless and sustained insulin levels with corresponding glucose reductions, without acute hypoglycemia caused by an insulin burst. These observations occurred at clinically relevant dose projections, demonstrating proof of concept of the potential for AB101 as a weekly subcutaneous basal insulin therapy in patients with diabetes mellitus.
"We are delighted by the results of our preclinical proof of concept pharmacology studies of AB101," said Brian Roberts, M.D., Vice President of Clinical Development at AntriaBio. "In addition to enabling significant progress toward filing our IND, these results affirmed our predicted dose-response and can be readily translated to clinically relevant doses and dose volumes in humans. We now have even greater confidence that similar safety and long-acting clinical pharmacology will be observed in clinical trials, which we are hopeful will one day translate into an important new treatment option for clinicians and patients."
"The availability of a longer-acting basal insulin therapy would provide physicians with a new treatment tool for their patients," said Philip Home, M.A., D. Phil., D.M., F.R.C.P., Professor of Diabetes Medicine at Newcastle University and previous clinical lead to the International Diabetes Federation (IDF) guidelines. "These results are encouraging, as they show that AB101 could be a promising new insulin therapy option for people with diabetes."
In receptor binding studies, AB101 drug substance was found to have an affinity for the insulin receptor that is similar to native insulin once bound, which predicts insulin activity in humans. The drug substance also displayed a low affinity for the IGF-1 receptor, which would indicate a low risk of mitogenicity. In liver cells, AB101 drug substance inhibited glucose production to the same magnitude and with the same potency as native insulin. The inhibitory effect on glucose production occurred at an IC50
of 0.24 nM, which was nearly identical to that of native insulin at an IC50
of 0.23 nM.
In vivo studies were conducted in rats and dogs. Fasting insulin and glucose were measured at baseline and multiple times over a 14-day period after a single subcutaneous dose (37.5 mg/kg or vehicle control in rats [n=6/group]; 10 mg/kg or 37.5 mg/kg in dogs [n=3/group]). In both species, slow and sustained increases in insulin were observed, with a Cmax
of > 30 ng/mL at 7 - 9 days post dose, and corresponding dose and species-dependent maximum reductions in glucose of 30 - 50%. The ratio of AUC(0-24h)
for insulin and glucose was < 1%. A similar sustained PK/PD profile was demonstrated in a diabetes animal model.

in Boston can be found here.
AntriaBio is currently engaged in additional studies for AB101 that support the filing of an Investigational New Drug (IND) application with the U.S. Food and Drug Administration.
