Alzheon Announces Initiation of Clinical Studies with ALZ-801 Bridging to Pivotal Phase 3 Study in Alzheimer’s Disease

Phase 1b Multiple Dose-Ranging Study and Tablet Bioequivalence Study
Will Provide Clinical Dose and Tablet Formulation Data to Support
ALZ-801 Phase 3 Program

FRAMINGHAM, Mass.–(BUSINESS WIRE)–Alzheon, Inc., a clinical-stage biopharmaceutical company focused on
developing new medicines for patients suffering from Alzheimer’s disease
and other neurological and psychiatric disorders, today announced the
initiation of two clinical studies with ALZ-801. ALZ-801 is a prodrug of
tramiprosate, which is a first-in-class small molecule inhibitor of
amyloid formation and neurotoxicity, being developed for the treatment
of Alzheimer’s disease. These studies will provide final clinical data
necessary to progress ALZ-801 into the Phase 3 program.

“With the robust body of existing positive clinical data in hand, we
believe these studies represent the last clinical steps before we start
the pivotal Phase 3 clinical study with our amyloid-targeting drug
candidate ALZ-801 in Alzheimer’s disease,” explained Martin Tolar, MD,
PhD, Founder, President and Chief Executive Officer of Alzheon.
“Building on the existing positive results related to ALZ-801 which
include the extensive clinical evidence from its active compound
tramiprosate, we have designed ALZ-801 to offer a unique approach and
potentially transformative treatment for patients with Alzheimer’s
disease. We are excited about the prospects for ALZ-801, as we have
optimized its pharmacokinetic and tolerability profile, and designed our
clinical plan building on the subgroup analysis of the Phase 3 studies
with tramiprosate that showed compelling efficacy results in
apolipoprotein E4 positive Alzheimer’s disease subjects.”

The Phase 1b multiple dose-ranging trial is a randomized, double-blind,
placebo-controlled, multiple ascending dose study to evaluate the
safety, tolerability and pharmacokinetics of oral ALZ-801 in healthy
elderly volunteers.

The tablet bioequivalence Phase 1b study is a solid dose formulation
study to examine the pharmacokinetics and food effect of a prototype
tablet formulation with a single oral dose of ALZ-801 in healthy elderly
volunteers, to guide development of final drug product formulation to be
used in the Phase 3 trial and, ultimately, for commercial development.

Completion of these two clinical studies is expected by 1Q 2016.
