Alzheon To Make Presentations On ALZ-801 And Its Anti-Oligomer Mechanism At The 10th Clinical Trials On Alzheimer’s Disease Congress

FRAMINGHAM, Mass.--(BUSINESS WIRE)--Alzheon, Inc., a clinical-stage biopharmaceutical company focused on developing new medicines for patients suffering from Alzheimer’s disease (AD) and other neurological and psychiatric disorders, today announced that the company will be making three presentations at the 10th Annual Clinical Trials on Alzheimer’s Disease (CTAD) congress to be held on November 1-4, 2017 in Boston.

These presentations highlight Alzheon’s lead drug candidate, ALZ-801, an orally-administered, anti-amyloid inhibitor that blocks the formation of toxic amyloid oligomers associated with the development and progression of AD. The results presented at CTAD further support the pivotal Phase 3 development of ALZ-801 as a Precision Medicine approach to treat Alzheimer’s patients with apolipoprotein e4 (APOE4) genotype, with future expansion to additional Alzheimer’s populations.

• An oral presentation at CTAD will discuss the central role of toxic amyloid oligomers in AD, highlighting Alzheon’s discovery of the novel mechanism of action of tramiprosate, the active agent in optimized prodrug ALZ-801 that blocks formation of toxic beta amyloid (Aß) oligomers. Recent findings also clinically translate the molecular mechanism of action of tramiprosate to clinical effects in Alzheimer’s disease patients.^1,2,3
• The company’s Precision Medicine clinical program for ALZ-801 is further supported by clinical data in a poster presentation at CTAD that analyzed efficacy and safety in AD patients with two APOE4 alleles (APOE4/4 homozygotes), who after completion of the North American Phase 3 trial continued into an Extension Study. Those patients who received tramiprosate 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 Aß oligomers play in AD pathogenesis, and the recently discovered molecular mechanism of tramiprosate, where tramiprosate inhibits Aß monomer aggregation and formation of toxic Aß oligomers at clinically relevant doses.¹
• In a poster presentation at CTAD, Alzheon will describe results from clinical studies of ALZ-801, an optimized prodrug of tramiprosate. The clinical studies demonstrated the improved tolerability and pharmacokinetics of ALZ-801 in comparison to oral tramiprosate, as well as establishing a dose that achieves equivalent target drug exposure. The completed ALZ-801 Phase 1 bridging program supports the pivotal Phase 3 clinical program for development of ALZ-801 as an oral, anti-oligomer inhibitor for targeting Aß pathology in the treatment of Alzheimer’s disease.

The details for the presentations are as follows:
