Sciele Pharma Announces That Addrenex Has Completed Enrollment Of Pivotal Phase III Trial For Clonicel For ADHD

Sciele Pharma, Inc. (NASDAQ: SCRX), a specialty pharmaceutical company, announced that Addrenex Pharmaceuticals has completed patient enrollment of its first Phase III clinical trial in the U.S. for Clonicel to treat attention deficit and hyperactivity disorder (ADHD) in children. Addrenex is also continuing to enroll patients in an additional Phase III trial using Clonicel in combination with stimulants such as methylphenidate and dextro-amphetamine/amphetamine to treat ADHD.

In July 2007, Sciele signed an exclusive licensing agreement with Addrenex to market a sustained-release formulation of clonidine hydrochloride for the treatment of ADHD and hypertension.

Ed Schutter, President and Chief Operating Officer of Sciele, said, "We are pleased to announce that Addrenex has completed patient enrollment for the Phase III trial using Clonicel to treat ADHD. Clonicel is an excellent strategic fit for our Pediatric product portfolio. Sciele has significantly expanded its product pipeline during the past year, and we now have seven products in our development pipeline: three are under review at the U.S. Food and Drug Administration (FDA) and four are in Phase III clinical trials."

Moise Khayrallah, Chief Executive Officer of Addrenex, said, "We are very pleased with the rapid progress we have made in testing Clonicel's potential ability to alleviate debilitating symptoms associated with ADHD, such as hyperactivity, impulsivity and aggression. Our goal is to provide another option for patients who need an alternative to stimulants or who may benefit from combination therapy using Clonicel together with other approved ADHD medications."
