, enzymes whose actions are thought to affect the accumulation of the amyloid plaques found in the brains of patients with Alzheimer’s disease. An example of such a molecule is semagacestat
. Élan is also studying other neurodegenerative diseases, such as Parkinson's disease. Élan, in collaboration with Wyeth, is currently conducting a Phase III clinical trial for bapineuzumab
, an experimental humanized monoclonal antibody
with a targeted indication of immunotherapeutic
treatment of mild to moderate Alzheimer’s disease. This humanized monoclonal antibody is designed and engineered to clear the neurotoxic beta-amyloid peptide that accumulates in the brains of patients with Alzheimer’s disease. Although initial results from an earlier Phase II clinical trial presented in July 2008 were inconclusive, Élan is hopeful that bapineuzumab will prove successful in the treatment of this disease.
In autoimmune diseases, Élan’s primary emphasis is studying cell trafficking to discover ways to provide disease-modifying therapies for autoimmune
diseases such as rheumatoid arthritis
, multiple sclerosis
and inflammatory bowel disease
. Research efforts are also focused on physiological and neuropathic pain

is a drug co-marketed by Biogen Idec
and Élan as "Tysabri". Tysabri is a monoclonal antibody that inhibits immune cells from crossing blood vessel walls to reach various tissues, including the brain. It has proven efficacy in the treatment of two serious autoimmune disorders: multiple sclerosis, and Crohn's disease
. In multiple sclerosis, Tysabri was shown to reduce relapses by 67% vs. a placebo in double-blind
studies. It slowed the progression of disability by 42%. While it is impossible to compare results across different clinical trials, the older generation drugs, i.e. interferons and glatiramer acetate
, are generally acknowledged as demonstrating about a 30-35% decrease in relapse rate vs. placebo; and only two drugs have been shown to decrease the progression of disability, but again only by around 20-40%.
