PRINCETON, N.J. and SAN DIEGO, July 22 /PRNewswire/ -- Tobira Therapeutics Inc., a clinical stage biotechnology company committed to research and product discovery for the treatment of life-threatening and life-altering infectious diseases, today announced pharmacokinetic data and results from two Phase I pharmacokinetic studies for TAK-652, an investigational compound being developed for the treatment of HIV. These data suggest that TAK-652 is rapidly absorbed and demonstrate relatively good oral bioavailability (as shown by the plasma TBR-652 concentration data) and has a long plasma half-life of TBR-652 (approximate mean of 35 hours) supporting once-daily dosing. Mean TBR-652 plasma concentrations were well above the predicted target plasma concentration (2ng/mL) with or without food. In both studies TBR-652 was safe and well tolerated in this healthy subject population when administered over a dose range of 10 mg to 800 mg in 2 tablet formulations. "These two Phase I studies provide encouraging support for TAK-652 as a therapeutic option for the treatment of HIV. We look forward to results from our on-going proof-of-concept study," said James Sapirstein, CEO.
