presentation at ICAD 2008, Medivation presented new data on
Dimebon's novel mitochondrial mechanism of action. Mitochondria generate
energy for cells and play important roles in mediating cell function and
survival. Mitochondrial dysfunction has been linked in the published
literature to both Alzheimer's and Huntington's diseases. Preclinical data
presented showed that Dimebon improves mitochondrial function in the
setting of cellular stress with very high potency. For example, Dimebon
treatment improved mitochondrial function and increased the number of
surviving cells after treatment with a cell toxin known as ionomycin in a
dose-dependent fashion. The effect of Dimebon to improve mitochondrial
dysfunction has been confirmed in the independent laboratory of Maria
Ankarcrona, Ph.D., Associate Professor at the Karolinska Institutet in
Sweden.
"All of the approved Alzheimer's disease drugs operate by one of two
mechanisms -- cholinesterase inhibition or NMDA-receptor antagonism," noted
Bengt Winblad, M.D., Ph.D., Head of the Karolinska Institutet's Alzheimer's
Disease Research Center. "The body of preclinical and clinical data
generated thus far convinces me that Dimebon is exerting its effects
through a different mechanism. The data presented today support the
hypothesis that Dimebon improves mitochondrial dysfunction. This is a novel
mechanism that may, in part, explain the clinical benefits seen in
Alzheimer's patients treated with Dimebon."
About the Pivotal Study
Dimebon's first pivotal Alzheimer's trial was a randomized,
double-blind, placebo-controlled study of 183 patients with mild to
moderate Alzheimer's disease. In this study, patients treated with Dimebon
experienced statistically significant improvements compared to placebo in
all the key aspects of the disease: memory and thinking, activities of
daily living, behavior and overall function -- after both six months and a
full year of treatment. Dimebon's benefit over placebo continued
