Pain Therapeutics and King Pharmaceuticals Announce Submission of New Drug Application for Remoxy

SAN MATEO, Calif. and BRISTOL, Tenn., June 10, 2008 (Healthcare Sales & Marketing Network) -- Pain Therapeutics, Inc. (NasdaqGM:PTIE ) and King Pharmaceuticals, Inc. (NYSE:KG ) today announced that a New Drug Application (NDA) for Remoxy(tm) has been submitted to the U.S. Food and Drug Administration (FDA). Remoxy, a unique long-acting formulation of oral oxycodone for moderate to severe chronic pain, is designed to resist common methods of prescription drug misuse and abuse.

Pain Therapeutics and King believe the NDA for Remoxy benefits from years of rigorous and independent scientific and clinical testing. The NDA includes animal and human data from extractability, pharmacokinetic, toxicology and clinical studies. If approved, the Companies believe Remoxy could be the first oxycodone on the market that is designed to reduce the risk of misuse and abuse.

``Our vision is to develop a line of opioid painkillers that minimize the risk of misuse, abuse or diversion,'' said Remi Barbier, Pain Therapeutics' chairman, president and chief executive officer. ``We believe the integrity of such drugs can deliver peace of mind to physicians, pharmacists and patients.''

Brian A. Markison, King's chairman, president and chief executive officer, stated, ``The NDA submission for Remoxy is an important advance in meeting the pain management needs of patients and prescribers concerned with addressing the risks of prescription pain medicine misuse and abuse within our communities.''

About the NDA for Remoxy

Pain Therapeutics submitted the NDA in accordance with the FDA's Electronic Common Technical Document specifications. Pursuant to Prescription Drug User Fee Act (PDUFA) guidelines, the FDA is expected to determine whether to accept the NDA for filing within 90 days. At that time the Companies will also learn if the NDA filing was granted priority review. A Priority Review designation is given to drugs that offer real advances in treatment, or provide a treatment where no adequate therapy exists. A Priority Review means that the time it takes FDA to review a NDA is reduced from 12 months to approximately 6 months.

About the Development Program for Remoxy

The development program for Remoxy consists of several clinical studies, including one pivotal Phase III study conducted under a Special Protocol Assessment (SPA), which evaluated the safety and efficacy of Remoxy in over 400 patients with osteoarthritis. With a SPA, the study design, endpoints and statistical analyses needed to support approval were agreed upon by the FDA prior to initiating the study and are considered binding. The Companies believe that the SPA for Remoxy remains in full-force without modification. The following summarizes the pivotal Phase III results:

* Pursuant to the SPA, the primary endpoint of the Remoxy pivotal
Phase III study was defined as mean decrease in pain intensity
scores between Remoxy and placebo during the 12-week treatment

* The study achieved a statistically significant result in its
primary endpoint (p less than 0.01).

* In addition, the study achieved statistically significant results
in secondary endpoints such as Quality of analgesia (p less than
0.01) and Global Assessment (p less than 0.01).

About Chronic Pain

It can affect an individual throughout his or her life, lasting several weeks, months, or even years at a time. The onset of chronic pain may be nociceptive (caused by ongoing tissue injury), neuropathic (caused by damage to the brain, spinal cord, or peripheral nerves), or disease specific (such as osteoarthritis or cancer).
