Alterity and UniQuest partner to reverse
bacterial resistance to antibiotics
New commercial opportunity for PBT2
MELBOURNE, AUSTRALIA AND SAN FRANCISCO, USA - 21st December
2020: Alterity Therapeutics (ASX: ATH, NASDAQ: ATHE) ("Alterity" or "the Company") has today
announced it has been granted a licence by UniQuest, the commercialisation company of The University of Queensland (UQ), to novel
zinc ionophore technology to combat antimicrobial resistance in superbugs.
Under the licence, Alterity has secured the worldwide exclusive
right to patented technology to develop and commercialise therapies that re-sensitise bacteria to antibiotics. The licensed technology
combines Alterity's PBT2 and other zinc ionophores with commonly used antibiotics to treat infections caused by multidrug
resistant bacteria. This is an opportunity for Alterity to further leverage its investment in PBT2.
PBT2, Alterity's most advanced zinc ionophore, breaks
the resistance of many important superbugs to available antibiotics, and is covered for this use by patents until 2038. Importantly,
PBT2 has previously completed long term preclinical safety studies and phase 2 clinical trial testing in other indications and
has been shown to have a favourable safety profile in those trials.
A recently published article in the high-impact journal Science
Translational Medicine1, showed that PBT2 could reverse antibiotic resistance to critical superbugs and demonstrate
efficacy in an animal model of sepsis.
Professor Mark Walker of The University of Queensland said:
"The results from our paper demonstrate that by breaking the resistance of superbugs, PBT2 and other zinc ionophores have
the potential to restore the efficacy of several widely available antibiotics."
The authors also noted that superbugs exposed to a combination
of PBT2 and antibiotics had a very low propensity to develop further resistance, making the emergence of cross-resistance to the
novel treatment unlikely. Thus, PBT2 may help address the issue of antimicrobial resistance without becoming part of the problem.
Geoffrey Kempler, Alterity's Chairman and CEO said: "Even
without the effects Covid-19, antibiotic resistant pathogens kill more than 700,000 people each year and represent a major threat
to global public health".
"The approach developed by our collaborators is novel
and potentially revolutionary. Existing antibiotics are losing the battle against these infections and science is struggling to
keep up as pathogens continually adapt. Because we can combine PBT2 with existing antibiotics, many of which are generic, this
approach has strong commercial value to Alterity."
The World Health Organisation has declared antibiotic resistant
bacteria a serious threat to global health that requires novel strategies to overcome the problem. PBT2 can break the resistance
of the most important resistant pathogens designated by the WHO.1,2
"The critical and urgent importance of this work is amplified
in the current context of Covid-19, because secondary bacterial infections associated with viral pandemics are an important cause
of mortality3. The need for effective antimicrobial regimens is very high," added Mr Kempler.
UniQuest CEO Dr Dean Moss said the technology had the potential
to be a catalyst for change in what was a significant and growing public health problem. "This partnership has significant
potential to help combat a growing and complex global problem," he said.
In exchange for the grant of exclusive worldwide rights, once
Alterity generates commercialization revenue, UniQuest is entitled to receive certain payments including milestone and royalty
payments commensurate with academic licenses.
Alterity intends to direct new resources to the project with
no impact on its lead commercialisation program for ATH434, which is advancing to Phase 2 in Multiple System Atrophy, a Parkinsonian
disorder with no approved therapy.

About Alterity Therapeutics Limited
Alterity Therapeutics Limited is a
biopharmaceutical company developing potential new treatments for neurodegenerative and other disease. It's lead
compound ATH434 is in clinical development for Multiple System Atrophy, a type of Parkinsonian disease.
Its second most advanced compound is PBT2,
a drug that is being explored for applications outside of neurodegenerative disease.
Alterity's core technology is covered by an extensive patent library including the 8-hydroxyquinoline chemical class which
covers PBT2 and other lead 8-hydroxyquinoline compounds. The majority of these patent cases include claims to compositions of matter
and the uses of these compounds in numerous neurological disorders. Notably these cases include composition of matter claims to
Alterity's product candidates for Parkinson's disease/movement disorders, brain cancer, and Light Chain Amyloidosis.
