“We are very delighted with the advancement of our ORADUR technology
platform and look forward to the continued progress of all of the products
under the King Pharmaceuticals and Pain Therapeutics alliance,” stated James
E. Brown, DVM, President and Chief Executive Officer. “Furthermore, we look
forward to developing additional innovative sustained release oral gel-cap
products that utilize other opioids and other active agents prone to abuse.”
About ORADUR
ORADUR sustained released oral gel-cap technology provides the unique
characteristics of Remoxy and the other opioid drug candidates subject to the
Pain Therapeutics and King Pharmaceuticals alliance. Products based on the
ORADUR technology can take the form of an easy to swallow gelatin capsule that
uses a high-viscosity base component, SABER(TM), to provide sustained release
of active ingredients for a period of from 12 to 24 hours of drug delivery.
Oral dosage forms based on the ORADUR gel-cap may also have the added benefit
of being less prone to abuse than other controlled release dosage forms on the
market today. ORADUR-based products can be manufactured by a simple process
using conventional methods making them readily scalable. These properties have
the potential to make ORADUR-based products an attractive option for
pharmaceutical companies that seek to develop tamper and abuse resistant oral
products.
About the Collaborations
On November 10, 2005, King Pharmaceuticals, Inc. and Pain Therapeutics,
Inc. announced that the companies have entered into a strategic alliance to
develop and commercialize Remoxy, an oral, long-acting, abuse-resistant
oxycodone capsule, and other ORADUR-based abuse-resistant products using three
other opioid drugs. The products under this collaboration are formulated with
DURECT Corporation’s ORADUR technology under a development and license
agreement between DURECT and Pain Therapeutics. Under the terms of the license
agreement between Pain Therapeutics and DURECT, Pain Therapeutics has
exclusive worldwide rights to develop and to commercialize Remoxy and other
ORADUR-based products using oxycodone and three other opioid drugs. DURECT is
reimbursed for formulation and other work performed under its agreement with
Pain Therapeutics, and will receive milestone payments based on the
achievement of certain technical, clinical or regulatory milestones, in
addition to receiving royalties on end product sales. Pain Therapeutics has
sublicensed the commercialization rights of Remoxy and other ORADUR-based
opioid products to King Pharmaceuticals. Oxycodone is the active drug
ingredient in Remoxy and in the branded product OxyContin(R), a leading brand
name opioid used in the treatment of moderate-to-severe pain.
