Alzheon to Present Novel Molecular Mechanism of Action and Long Term Clinical Efficacy Data for Lead Candidate ALZ-801 at the Alzheimer’s Association International Conference

Presentations Highlight Recent Discovery of Inhibition of Formation of Toxic Beta Amyloid Oligomers and New Insights for Precision Medicine Approach for ALZ-801

FRAMINGHAM, Mass., June 22, 2017 – 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 that the company will be making three presentations at the Alzheimer’s Association International Conference (AAIC) to be held in London on July 16-20, 2017.

The presentations highlight Alzheon’s discovery of the novel mechanism of action of tramiprosate, the active agent in optimized prodrug ALZ-801, blocking formation of toxic beta amyloid (Aβ) oligomers, as well as the clinical translation of the molecular mechanism of action of tramiprosate to clinical effects in Alzheimer’s disease (AD) patients.  The company’s precision medicine clinical program for ALZ-801 is further supported by recently published new analyses of Phase 3 data that shows the largest efficacy signals of tramiprosate in APOE4/4 homozygous patients with Mild Alzheimer’s disease.1,2  This AAIC clinical presentation further analyzed efficacy and safety in APOE4/4 homozygotes with AD who continued into an Extension Study for an additional 52 weeks, where all subjects received high dose tramiprosate. APOE4/4 AD subjects receiving the high dose of tramiprosate over 130 weeks showed persistent efficacy, compared to subjects who had a delayed start on active drug (i.e., initial placebo-treated subjects).  These clinical benefits in APOE4/4 AD patients are consistent with the key role Aβ oligomers play in AD pathogenesis and the recently discovered molecular mechanism of tramiprosate, where tramiprosate inhibits Aβ monomer aggregation and formation of toxic Aβ oligomers at clinically relevant doses.

The details for the presentations are as follows:
