Alterity Therapeutics Presents at the American Academy of Neurology Annual Meeting

Alterity Therapeutics Limited, (ASX: ATH, NASDAQ: ATHE) (“Alterity” or “the Company”) will present clinical data from its lead drug candidate PBT434 at the American Academy of Neurology Annual Meeting in Philadelphia, USA, from 5-9th May 2019.

Alterity will feature prominently at the Annual Meeting with a Platform Presentation on Sunday 5th May featuring data from the company’s Phase 1 clinical trial and a Poster Presentation featuring pre-clinical data on Thursday 9th May.

The American Academy of Neurology Annual Meeting is one of the largest gatherings of clinicians and researchers focusing on neurology in the world. It has been running for more than 70 years.

The Platform Presentation is titled: A First in Human Study of PBT434, a Novel Small Molecule Inhibitor of α-Synuclein Aggregation and will present first data from the current clinical study program. Details of this presentation, which is to be delivered by David Stamler, MD, Chief Medical Officer & Senior VP Clinical Development, will be disclosed to investors concurrently with the presentation.

The Phase 1 Clinical Trial for PBT434 commenced in 2018 in Australia, recruiting healthy adult and older adult (≥ 65) volunteers with the primary goals of assessing the safety and tolerability of PBT434 after single and multiple oral dose administration. Secondary goals include evaluating pharmacokinetic measures that will allow Alterity understand how PBT434 is absorbed and metabolised by the body.

The Poster Presentation appearing on Thursday 9th May is titled: PBT434 Prevents α-Synuclein Aggregation, Neuron Loss, Motor Dysfunction and Reduces Glial Cell Inclusions in a Transgenic Mouse Model of Multiple System Atrophy1.

This study evaluated the efficacy of PBT434 in a mouse model of multiple system atrophy (MSA), which is a rare and rapidly progressive neurological disorder that affects adults. MSA is characterized by motor symptoms similar to those found in Parkinson’s disease, loss of ability to coordinate voluntary movements, and impaired ability to regulate involuntary body functions such as blood pressure, bowel and bladder control and sexual function. Symptoms typically commence between the ages of 50 and 60 years of age and it has no known cause. The Poster will be lodged to coincide with the session later in the week.

PBT434 is the first of a new generation of small molecules designed to block the accumulation and aggregation of α-synuclein. α-synuclein is of great interest because aggregated forms of the protein are considered a pathological hallmark of Parkinsonian conditions and are a recognised therapeutic target by neuroscientists and clinicians.

About Alterity Therapeutics Limited

Alterity’s lead candidate, PBT434, is the first of a new generation of small molecules designed to inhibit the aggregation of pathological proteins implicated in neurodegeneration. PBT434 has been shown to reduce abnormal accumulation of α-synuclein and tau proteins in animal models of disease by restoring normal iron balance in the brain. In this way, it has excellent potential to treat various forms of atypical Parkinsonism such as Multiple System Atrophy (MSA) and Progressive Supranuclear Palsy (PSP).
