Satori Pharmaceuticals Demonstrates its Approach to Modulating Gamma-Secretase Effective In Reducing Plaque-Forming Amyloid Beta Peptide

CAMBRIDGE, Mass., July 18, 2011 /PRNewswire/ -- Satori(TM) Pharmaceuticals today announced the presentation of two posters at the Alzheimer's Association International Conference on Alzheimer's Disease (ICAD) taking place in Paris, France, July 16-21, 2011. Both posters illuminate the unique biological activity associated with Satori's approach to the treatment of Alzheimer's disease. The posters were titled, "Gamma-secretase modulators do not show a potency shift in high expressing model systems," and "Classification of gamma-secretase modulators by their effect on pharmacological profiles of amyloid beta peptides."

Alzheimer's disease is characterized by the formation of amyloid beta plaques in the brain. Plaques are primarily composed of two main forms of amyloid beta: AB40 and AB42. Satori's program aims to reduce the amount of AB42 in the brain by modulating gamma-secretase, thus lowering brain amyloid, plaque formation and associated damage to normal neuronal function.

"The studies presented at ICAD demonstrate that by modulating gamma-secretase we are able to effectively lower AB42 levels - the main component of amyloid beta plaques," said Jeff Ives, Ph.D., CEO and Board Member of Satori Pharmaceuticals. "Some of the other compounds in development target all gamma-secretase activity, whereas our approach modulates gamma-secretase in a way that selectively reduces the production of AB42."

Amyloid beta is believed to have a role in normal neuronal function and shorter forms of amyloid beta may also reduce aggregation of AB42. In addition, complete inhibition of gamma-secretase activity can lead to significant side effects by interfering with the processing of Notch and other substrates. Satori's approach to selectively modulating gamma-secretase with the Company's proprietary class of molecules is the subject of the posters presented at ICAD. The posters demonstrate that gamma-secretase modulators (GSMs) achieve a reduction in AB42 levels without altering total amyloid beta levels in cell lines and animal models of disease. These results are promising for the continuation of Satori's GSM program. The Company intends to file an IND on the lead GSM in 2012.
