ALZA Corporation Modifies U.S. Clinical Development Program For OROS Hydromorphone (AP-77)

MOUNTAIN VIEW, Calif., Dec. 1 /PRNewswire/ -- ALZA Corporation today announced that it is modifying the U.S. clinical development program for OROS Hydromorphone (AP-77) for chronic pain. The company is considering different options for moving forward following recent discussions with the U.S. Food and Drug Administration in which it became clear that an additional clinical trial would be required to meet the agency's standards for approval. The decision to modify the clinical development program was not related to any safety issues with the medication.

The clinical development program in other regions of the world will continue, as previously planned. AP-77 is expected to launch in the European Union in 2006.

ALZA Corporation, a wholly owned subsidiary of Johnson & Johnson, is leading the next generation of drug delivery, with the world's broadest array of technology platforms, including oral, transdermal, implantable, and liposomal technologies. ALZA's drug delivery technologies have been incorporated in more than 30 products, which are marketed in more than 80 countries worldwide.
