DUBLIN & TORONTO & VIENNA--(BUSINESS WIRE)--Elan Corporation, plc (NYSE: ELN) and Transition Therapeutics Inc. (TSX: TTH, NASDAQ: TTHI) today presented Phase 1 data demonstrating that treatment with ELND005 (scyllo-inositol formerly known as AZD-103), achieves desired concentrations in human brain tissue and cerebrospinal fluid when given orally. Preclinical data also were presented showing that ELND005 administration is associated with preservation of choline acetyltransferase (ChAT), reflecting preservation of nerve cells that are critical to memory function in the brain. ELND005 is an orally-administered drug candidate in Phase 2 trials for the treatment of mild to moderate Alzheimer’s disease. These results were presented at the 2009 Alzheimer’s Association International Conference on Alzheimer’s Disease (ICAD 2009) in Vienna, Austria.
