Avagacestat (BMS-708163) is an oral gamma secretase inhibitor designed for selective inhibition of amyloid beta (Aβ) synthesis. Avagacestat was in development by Bristol-Myers Squibb for the treatment of Alzheimer's disease (AD). Avagacestat is a potent, selective, orally bioavailable γ-secretase inhibitor of Aβ40 and Aβ42 with IC50 of 0.3 nM and 0.27 nM, demonstrating a 193-fold selectivity against Notch. In November 2012, Bristol-Myers Squibb terminated clinical trials of the drug and announced its decision to end further development of avagacestat

Sample Use Guides

In Vivo Use Guide

Of the four Avagacestat (BMS-708163) doses evaluated (25 mg, 50 mg, 100 mg and 125 mg/day), doses below 100 mg/day demonstrated acceptable tolerability profiles for further development and were associated with discontinuation rates comparable with placebo. BMS-708163 doses at or above 100 mg were associated with higher discontinuation rates, most commonly due to gastrointestinal and dermatological side effects.

Route of Administration: Oral
