FDA Grants Fast Track Designation to Alzheimer's Disease Drug Candidate AZD-103/ELND005

TORONTO, April 3 (Healthcare Sales & Marketing Network) - Transition Therapeutics Inc. ("Transition") (TSX: TTH ) announced today that the United States Food and Drug Administration ("FDA") has granted Fast Track designation to investigational drug candidate AZD-103/ELND005, being developed in collaboration with Elan Corporation, plc. ("Elan") (NYSE: ELN ) for the treatment of Alzheimer's disease. AZD-103/ELND005 is currently being evaluated in multiple Phase I clinical studies, and the companies anticipate starting Phase II clinical studies around the end of 2007.

"The decision by the FDA is very encouraging news for Alzheimer's disease patients and their families, and we believe it reflects the considerable potential for AZD-103 in this area," said Dr. Tony Cruz, Chairman and Chief Executive Officer of Transition. "Transition and Elan welcome this decision and look forward to working with the FDA and the clinical community to make continued progress on AZD-103/ELND005."

Under the FDA Modernization Act of 1997, Fast Track designation is intended to facilitate the development and expedite the review of a drug or biologic if it is intended for the treatment of a serious or life-threatening condition, and it demonstrates the potential to address unmet medical needs for such a condition.
