Alpharma Withdraws Application for Painkiller

Alpharma Withdraws Application for Painkiller

4/22/2008

BRIDGEWATER, NJ -- Apr 21, 2008 -- Alpharma, a global specialty pharmaceutical company, today announced that it has withdrawn its New Drug Application ("NDA") for EMBEDA™ (morphine sulfate extended-release with sequestered naltrexone hydrochloride) Capsules, and plans to resubmit a revised application as soon as possible. While the initial NDA submission qualified for a priority review, certain technical issues around data presentation prevented a complete evaluation by the U.S. Food and Drug Administration (the "FDA") within the six month time period permissible for a priority review. The Company expects to address the submission issues and re-qualify for priority review in its resubmission. Alpharma is fully committed to collaborating with the FDA to complete a timely review of the EMBEDA™ NDA, and continues to anticipate a first quarter 2009 launch following approval.

EMBEDA™ was developed with Alpharma's proprietary technology, which combines an extended release opioid with sequestered naltrexone, an opioid antagonist. In clinical trials, when EMBEDA™ was taken as directed, it provided effective pain relief and the sequestered naltrexone passed through the body without effect. When the EMBEDA™ Capsule was crushed, chewed or dissolved, which are common approaches abusers use to tamper with the product in order to gain euphoria, the naltrexone was released thereby significantly reducing the euphoric effect of the opioid.
