Pain Therapeutics Announces Positive Phase I Study Results With PTI-202 Wednesday November 29, 9:00 am ET SOUTH SAN FRANCISCO, Calif., Nov. 29 -- Pain Therapeutics, Inc. (Nasdaq: PTIE - News) announced positive results today from a Phase I clinical trial evaluating PTI-202, the Company's second abuse- resistant opioid painkiller. This clinical trial was designed to investigate the safety, tolerability, pharmacokinetics and pharmacodynamic profile of a single, oral dose of PTI-202 in healthy volunteers. We believe results also indicate PTI-202 is safe and well-tolerated and its release profile appears well-suited to use with a chronic pain population. There were no unexpected adverse events in this trial. "We are very pleased with the results of this clinical trial," said Remi Barbier, president and chief executive officer. "These results in healthy volunteers nicely recapitulate what we previously observed in animal studies and provide further evidence that the underlying abuse-resistant platform can be applied across different opioid painkillers." PTI-202 is a novel abuse-resistant formulation of an opioid painkiller. Its active pharmaceutical ingredient remains undisclosed. PTI-202 is intended to meet the needs of physicians who appropriately prescribe opioid painkillers and who seek to minimize the risks of drug diversion, abuse or accidental patient misuse. About Pain Therapeutics, Inc. Pain Therapeutics is a biopharmaceutical company that develops novel drugs for pain management and oncology.
