MORRISTOWN, N.J., May 05, 2015 (BUSINESS WIRE) — Pernix Therapeutics Holdings, IncPTX, +0.94% a specialty pharmaceutical company, today announced the successful completion of a human pharmacokinetic equivalence study with ZX007, an innovative abuse deterrent tablet formulation of hydrocodone bitartrate. The clinical study evaluated the pharmacokinetics and safety of prototype formulations developed by Altus Formulation using its proprietary INTELLITABTM technology, for comparison with Zohydro® ER, resulting in the selection of the final ZX007 prototype for pivotal clinical studies. Damon Smith, CEO of Altus Formulation said; “We are very happy that ZX007 is performing in the way we expected in human studies and we look forward to working with the Pernix team to complete development”.

Study results demonstrated that the selected ZX007 formulation is pharmacokinetically equivalent with currently marketed Zohydro ER with BeadTek and that it has a consistent safety profile. Selection of the formulation enables the start of pivotal clinical studies later this year, paving the way for the NDA submission for ZX007 in mid-2016. Doug Drysdale, President, Chairman and CEO of Pernix said, “We are pleased to have identified the right formulation to move forward into clinical trials, to bring the clinical benefits of ZX007 to patients suffering with chronic pain. Pernix remains committed to supporting the appropriate use of opioids, which includes following best practices for physicians and their patients living with chronic pain, as well as making abuse-deterrent products available. ”
