PART

ITEM
1. BUSINESS
Overview
and Strategy
Anavex
Life Sciences Corp. is a clinical stage biopharmaceutical company engaged in the development of differentiated therapeutics by
applying precision medicine to central nervous system (“CNS”) diseases with high unmet need. We analyze genomic data
from clinical studies to identify biomarkers, which we use to select patients that will receive the therapeutic benefit for the
treatment of neurodegenerative and neurodevelopmental diseases.
Our
lead compound, ANAVEX®2-73, is being developed to treat Alzheimer’s disease, Parkinson’s disease and
potentially other central nervous system diseases, including rare diseases, such as Rett syndrome, a rare severe neurological
monogenic disorder caused by mutations in the X-linked gene, methyl-CpG-binding protein 2 (“MECP2”).
We currently have two core programs and two
seed programs. Our core programs are at various stages of clinical and preclinical development, in neurodegenerative and neurodevelopmental
diseases.
The
following table summarizes key information about our programs:
Anavex
has a portfolio of compounds varying in sigma-1 receptor (S1R) binding activities. The SIGMAR1 gene encodes the S1R protein, which
is an intracellular chaperone protein with important roles in cellular communication. S1R is also involved in transcriptional
regulation at the nuclear envelope and restores homeostasis and stimulates recovery of cell function when activated. In order
to validate the ability of our compounds to activate quantitatively the S1R, we performed, in collaboration with Stanford University,
a quantitative Positron Emission Tomography (PET) imaging scan in mice, which demonstrated a dose-dependent ANAVEX®2-73
target engagement or receptor occupancy (RO) with S1R in the brain.
Cellular
Homeostasis
Many
diseases are possibly directly caused by chronic homeostatic imbalances or cellular stress of brain cells. In pediatric diseases
like Rett syndrome or infantile spasms, the chronic cellular stress is possibly caused by the presence of a constant genetic mutation.
In neurodegenerative diseases, such as Alzheimer’s and Parkinson’s diseases, chronic cellular stress is possibly caused
by age-correlated buildup of cellular insult and hence chronic cellular stress. Specifically, defects in homeostasis of protein
or ribonucleic acid (“RNA”) lead to the death of neurons and dysfunction of the nervous system. The spreading of protein
aggregates resulting in a proteinopathy, a characteristic finding in Alzheimer’s and Parkinson’s diseases that results
from disorders of protein synthesis, trafficking, folding, processing or degradation in cells. The clearance of macromolecules
in the brain is particularly susceptible to imbalances that result in aggregation and degeneration in nerve cells. For example,
Alzheimer’s disease pathology is characterized by the presence of amyloid plaques, neurofibrillary tangles, which are aggregates
of hyperphosphorylated Tau protein that are a marker of other diseases known as tauopathies as well as inflammation of microglia.
With the SIGMAR1 activation through SIGMAR1 agonists like ANAVEX®2-73, our approach is to restore cellular balance,
i.e. homeostasis. Therapies that correct defects in cellular homeostasis might have the potential to halt or delay neurodevelopmental
and neurodegenerative disease progression.
ANAVEX®2-73-specific
Biomarkers
A
full genomic analysis of Alzheimer’s disease (AD) patients treated with ANAVEX®2-73 resulted in the identification
of actionable genetic variants. A significant impact of the genomic biomarkers SIGMAR1, the direct target of ANAVEX®2-73
and COMT, a gene involved in memory function, on the drug response level was identified, leading to an early ANAVEX®2-73-specific
biomarker hypothesis. It is expected that excluding patients with these two identified biomarker variants (approximately
10%-20% of the population) in prospective studies would identify approximately 80%-90% patients that would display clinically
significant improved functional and cognitive scores. The consistency between the identified DNA and RNA data related to ANAVEX®2-73,
which are considered independent of AD pathology, as well as multiple endpoints and time-points, provides support for precision
medicine clinical development of ANAVEX®2-73 by using genetic biomarkers identified within the study population
itself to target patients who are most likely to respond to ANAVEX®2-73 treatment in AD as well as indications
like Parkinson’s disease dementia (PDD) or Rett syndrome (RTT) in which ANAVEX®2-73 is currently studied.
Clinical
Studies Overview
Alzheimer’s
Disease
In
November 2016, we completed a Phase 2a clinical trial, consisting of PART A and PART B, which lasted a total of 57 weeks, for
ANAVEX®2-73 in mild-to-moderate Alzheimer’s patients. This open-label randomized trial met both primary and
secondary endpoints and was designed to assess the safety and exploratory efficacy of ANAVEX®2-73 in 32 patients.
ANAVEX®2-73 targets sigma-1 and muscarinic receptors, which have been shown in preclinical studies to reduce stress
levels in the brain believed to restore cellular homeostasis and to reverse the pathological hallmarks observed in Alzheimer’s
disease. The Phase 2a trial demonstrated positive pharmacokinetic (PK) and pharmacodynamic (PD) data, which established a concentration-effect
relationship between ANAVEX®2-73 and study measurements. These measures obtained from all patients who participated
in the entire 57 weeks include exploratory cognitive and functional scores as well as biomarker signals of brain activity. Additionally,
the study appears to show that ANAVEX®2-73 activity is enhanced by its active metabolite (ANAVEX19-144), which
also targets the sigma-1 receptor and has a half-life approximately twice as long as the parent molecule.
Two
consecutive trial extensions for the Phase 2a trial have allowed participants who completed the 52-week PART B of the study to
continue taking ANAVEX®2-73, providing an opportunity to gather extended safety data for a cumulative time period
of five years. In August 2020, patients completing these Phase 2a trial extensions were granted continued access to treatment
with ANAVEX®2-73 through the Australian Government Department of Health – Therapeutic Goods Administration
(TGA) compassionate use Special Access Scheme.
A
larger Phase 2b/3 double-blind, placebo-controlled study of ANAVEX®2-73 in Alzheimer’s disease
commenced in August 2018. The Phase 2b/3 study will enroll approximately 450 patients for 48 weeks, randomized 1:1:1 to two
different ANAVEX®2-73 doses or placebo. The trial commenced in Australia; and during fiscal 2020 additional
regions were added in the United Kingdom, The Netherlands, Germany and Canada. The ANAVEX®2-73 Phase 2b/3
study design incorporates genomic precision medicine biomarkers identified in the ANAVEX®2-73 Phase 2a study.
Primary and secondary endpoints will assess safety and both cognitive and functional efficacy, measured through
Alzheimer’s Disease Assessment Scale – Cognition (ADAS-Cog), ADCS-ADL and Clinical Dementia Rating – Sum of
Boxes for cognition and function (CDR-SB).
In
October 2019, we initiated a long-term open label extension study of ANAVEX®2-73, entitled the ATTENTION-AD study,
for patients who have completed the 48-week Phase 2b/3 placebo-controlled trial referenced above. This study is expected to last
two years and will give patients the opportunity to continue their treatment.
Rett
Syndrome
In
February 2016, we presented positive preclinical data for ANAVEX®2-73 in Rett syndrome, a rare neurodevelopmental
disease. The study was funded by the International Rett Syndrome Foundation (“Rettsyndrome.org”). In January 2017,
we were awarded a financial grant from Rettsyndrome.org of a minimum of $0.6 million to cover some of the costs of a multicenter
Phase 2 clinical trial of ANAVEX®2-73 for the treatment of Rett syndrome. This award was received in quarterly
instalments which commenced during fiscal 2018.
In
March 2019, we commenced the first Phase 2 clinical trial in a planned Rett syndrome program of ANAVEX®2-73 for
the treatment of Rett syndrome. The studies will be conducted in a range of patient age demographics and geographic regions.
The first Phase 2 study, which took place
in the United States, was completed in December 2020. This trial was a randomized double-blind, placebo-controlled safety, tolerability,
pharmacokinetic and efficacy study of oral liquid ANAVEX®2-73formulation in 25 adult female patients with Rett
syndrome over a 7-week treatment period including ANAVEX®2-73-specific genomic precision medicine biomarkers.
The primary endpoint of the trial was safety. The convenient oral liquid once-daily dosing of 5 mg ANAVEX®2-73
was well-tolerated and demonstrated dose-proportional PK (pharmacokinetics). All secondary efficacy endpoints of the trial showed
statistically significant and clinically meaningful, drug exposure-dependent response in the Rett Syndrome Behaviour Questionnaire
(RSBQ) Total scores, when compared to placebo, in the ITT cohort (all participants, p = 0.048). 66.7% of ANAVEX®2-73
treated subjects showed a statistically significant improvement in drug exposure-dependent RSBQ response as compared to 10% of
the subjects on placebo in the ITT cohort (all participants, p = 0.011). ANAVEX®2-73 treatment resulted in a sustained
improvement in Clinical Global Impression Improvement (CGI-I) scores throughout the 7-week study, when compared to placebo in
the ITT cohort (all participants, p = 0.014). 86.7% of ANAVEX®2-73 treated subjects showed a statistically significant
CGI-I response, defined as sustained improvement to treatment, as compared to 40% of the subjects on placebo in the ITT cohort
(all participants, p = 0.014). Consistent with previous ANAVEX®2-73 clinical trials, patients carrying the common
form of the SIGMAR1 gene treated with ANAVEX®2-73 experienced stronger improvements in the prespecified efficacy
endpoints.
The second Phase 2 study of ANAVEX®2-73
for the treatment of Rett syndrome, called the AVATAR study, commenced in June 2019. This study is taking place in Australia and
the United Kingdom using a convenient once-daily oral liquid ANAVEX®2-73 formulation at a higher dose than the
U.S. based Phase 2 study for Rett syndrome. The study will evaluate the safety and efficacy of ANAVEX®2-73 in approximately
33 patients over a 7-week treatment period including ANAVEX®2-73 specific precision medicine biomarkers. All patients
who participate in the study will be eligible to receive ANAVEX®2-73 under a voluntary open label extension protocol.
In
July 2020, we commenced the third study of ANAVEX®2-73 for the treatment of Rett syndrome, called the EXCELLENCE
study. This Phase 2/3 study in pediatric patients with Rett syndrome is using a convenient once-daily oral liquid ANAVEX®2-73
formulation. The study will evaluate the safety and efficacy of ANAVEX®2-73 in at least 69 pediatric patients,
aged 5 to 18, over a 12-week treatment period incorporating ANAVEX®2-73 specific precision medicine biomarkers.
All patients who participate in the study will be eligible to receive ANAVEX®2-73 under a voluntary open label
extension protocol.
Parkinson’s
Disease
In
September 2016, we presented positive preclinical data for ANAVEX®2-73 in Parkinson’s disease, which demonstrated
significant improvements on all measures: behavioral, histopathological, and neuroinflammatory endpoints. The study was funded
by the Michael J. Fox Foundation. Additional data was announced in October 2017 from the model for experimental parkinsonism.
The data presented indicates that ANAVEX®2-73 induces robust neurorestoration in experimental parkinsonism. The
encouraging results we have gathered in this model, coupled with the favorable profile of this compound in the Alzheimer’s
disease trial, support the notion that ANAVEX®2-73 is a promising clinical candidate drug for Parkinson’s
disease dementia.
In
October 2020, we completed a double-blind, randomized, placebo-controlled proof-of-concept Phase 2 trial with ANAVEX®2-73
in Parkinson’s Disease Dementia (PDD), to study the effect of the compound on both the cognitive and motor impairment of
Parkinson’s disease. The Phase 2 study enrolled approximately 132 patients for 14 weeks, randomized 1:1:1 to two different
ANAVEX®2-73 doses, 30mg and 50mg, or placebo. The ANAVEX®2-73 Phase 2 PDD study design incorporated
genomic precision medicine biomarkers identified in the ANAVEX®2-73 Phase 2a study.
The
study found that ANAVEX®2-73 was safe and well tolerated in oral doses up to 50mg once daily. The results show
clinically meaningful, dose-dependent, and statistically significant improvements in the Cognitive Drug Research (CDR) computerized
assessment system analysis. The study confirmed the precision medicine approach of targeting SIGMAR1 as a genetic biomarker in
response to ANAVEX®2-73.
In
August 2020, we announced a financial commitment by Shake It Up Australia Foundation for Parkinson’s Research to fund up
to 50% of the costs of an Australian clinical study to develop ANAVEX®2-73 for the disease modifying treatment
of Parkinson’s disease. The financial commitment would be made through private placement purchases of our common stock at
200% of the fair market value on the purchase date and will be contingent upon the completion of certain clinical trial milestones
relating to the proposed clinical trial. The proposed clinical trial will use a convenient, once-daily oral ANAVEX®2-73
formulation to confirm the previously established potential disease modifying features of ANAVEX®2-73 in an animal
model of Parkinson’s disease. Safety and efficacy will be investigated in an appropriately powered placebo-controlled clinical
study of Parkinson’s disease patients over at least 48-weeks including ANAVEX®2-73-specific precision medicine
biomarkers.
Frontotemporal
Dementia
In
July 2020, we commenced the First-in-Human Phase 1 clinical trial of ANAVEX®3-71, which was previously granted
orphan drug designation for the treatment of Frontotemporal Dementia (FTD) by the FDA. ANAVEX®3-71 is an orally
administered small molecule targeting sigma-1 and M1 muscarinic receptors that is designed to be beneficial for neurodegenerative
diseases. In preclinical studies, ANAVEX®3-71 demonstrated disease-modifying
activity against the major hallmarks of Alzheimer’s disease in transgenic (3xTg-AD) mice, including cognitive deficits,
amyloid and tau pathologies, as well as beneficial effects on mitochondrial dysfunction and neuroinflammation.
The
Phase 1 clinical trial will be a prospective double-blind, randomized, placebo-controlled study. A total of at least 36 healthy
male and female subjects will be included. Single escalating doses of ANAVEX®3-71 will be administered in order
to evaluate the safety, tolerability, and pharmacokinetics (PK) of ANAVEX®3-71 and the effects of food and gender
on its PK in healthy volunteers. This study is expected to be followed by longer duration dosing including patients with FTD or
other dementia indications with unmet medical need, incorporating exploratory efficacy and disease biomarker measures.
Our
Pipeline
Our
research and development pipeline includes ANAVEX®2-73 currently in three different clinical study indications,
and several other compounds in different stages of clinical and pre-clinical study.
Our
proprietary SIGMACEPTORTM Discovery Platform produced small molecule drug candidates with unique modes of action, based on
our understanding of sigma receptors. Sigma receptors may be targets for therapeutics to combat many human diseases, both of neurodegenerative
nature, including Alzheimer’s disease, as well as of neurodevelopmental nature, like Rett syndrome. When bound by the appropriate
ligands, sigma receptors influence the functioning of multiple biochemical signals that are involved in the pathogenesis (origin
or development) of disease. Multiple viruses including SARS-CoV-2 (COVID-19) induce cellular stress by intrinsic mitochondrial
apoptosis and other related cellular processes, in order to ensure survival and replication. Hence, it is possible that S1R could
play a role in modulating the cellular response to viral infection and ameliorate pathogenesis.
Compounds
that have been subjects of our research include the following:
ANAVEX®2-73

ANAVEX®2-73
may offer a disease-modifying approach in neurodegenerative and neurodevelopmental diseases by activation of sigma-1 receptors.
In
Rett syndrome, administration of ANAVEX®2-73 resulted in both significant and dose related improvements in an array
of behavioral paradigms in the MECP2 HET Rett syndrome disease model. In addition, in a further experiment sponsored by Rettsyndrome.org,
ANAVEX®2-73 was evaluated in automatic visual response and respiration tests in 7-month old mice, an age at which
advanced pathology is evident. Vehicle-treated MECP2 mice demonstrated fewer automatic visual responses than wild-type mice. Treatment
with ANAVEX®2-73 for four weeks significantly increased the automatic visual response in the MECP2 Rett syndrome
disease mouse. Additionally, chronic oral dosing daily for 6.5 weeks of ANAVEX®2-73 starting at ~5.5 weeks of age
was conducted in the MECP2 HET Rett syndrome disease mouse model assessed the different aspects of muscular coordination, balance,
motor learning and muscular strengths, some of the core deficits observed in Rett syndrome. Administration of ANAVEX®2-73
resulted in both significant and dose related improvements in an array of these behavioral paradigms in the MECP2 HET Rett syndrome
disease model.
In
March 2019, we commenced the first Phase 2 clinical trial in a planned Rett syndrome program of ANAVEX®2-73 for
the treatment of Rett syndrome. This study, which took place in the United States, was completed in December 2020, however two
other clinical trials in Rett syndrome, the AVATAR study and the EXCELLENCE study, are still underway. The studies are being conducted
in a range of patient age demographics and geographic regions, as more fully described above under Clinical Studies Overview
– Rett Syndrome.
In
May 2016 and June 2016, the FDA granted Orphan Drug Designation to ANAVEX®2-73 for the treatment of Rett syndrome
and infantile spasms, respectively. In November 2019, the FDA granted to ANAVEX®2-73 the Rare Pediatric Disease
(RPD) designation for the treatment of Rett syndrome. The RPD designation provides priority review by the FDA to encourage the
development of treatments for rare pediatric diseases.
Further,
in February 2020, the FDA granted Fast Track designation for the ANAVEX®2-73 clinical development program for the
treatment of Rett syndrome. The FDA Fast Track program is designed to facilitate and expedite the development and review of new
drugs to address unmet medical needs in the treatment of serious and life-threatening conditions.
For
Parkinson’s disease, data demonstrates significant improvements and restoration of function in a disease modifying animal
model of Parkinson’s disease. Significant improvements were seen on all measures tested: behavioral, histopathological,
and neuroinflammatory endpoints. In October 2020, we completed a double-blind, randomized, placebo-controlled proof-of-concept
Phase 2 trial with ANAVEX®2-73 in Parkinson’s Disease Dementia (PDD), to study the effect of the compound
on both the cognitive and motor impairment of Parkinson’s disease. The Phase 2 study enrolled approximately 132 patients
for 14 weeks, randomized 1:1:1 to two different ANAVEX®2-73 doses, 30mg and 50mg, or placebo. The ANAVEX®2-73
Phase 2 PDD study design incorporated genomic precision medicine biomarkers identified in the ANAVEX®2-73 Phase
2a study.
The
study found that ANAVEX®2-73 was safe and well tolerated in oral doses up to 50mg once daily. The results show
clinically meaningful, dose-dependent, and statistically significant improvements in the Cognitive Drug Research (CDR) computerized
assessment system analysis. We anticipate conducting further clinical trials of ANAVEX®2-73 in Parkinson’s
disease dementia after submitting the results of the study to the FDA to obtain regulatory guidance.
In
Alzheimer’s disease (AD) animal models, ANAVEX®2-73 has shown pharmacological, histological and behavioral
evidence as a potential neuroprotective, anti-amnesic, anti-convulsive and anti-depressive therapeutic agent, due to its potent
affinity to sigma-1 receptors and moderate affinities to M1-4 type muscarinic receptors. In addition, ANAVEX®2-73
has shown a potential dual mechanism which may impact both amyloid and tau pathology. In a transgenic AD animal model Tg2576,
ANAVEX®2-73 induced a statistically significant neuroprotective effect against the development of oxidative stress
in the mouse brain, as well as significantly increased the expression of functional and synaptic plasticity markers that is apparently
amyloid-beta independent. It also statistically alleviated the learning and memory deficits developed over time in the animals,
regardless of sex, both in terms of spatial working memory and long-term spatial reference memory.
Based
on the results of pre-clinical testing, we initiated and completed a Phase 1 single ascending dose (SAD) clinical trial of ANAVEX®2-73.
In this Phase 1 SAD trial, the maximum tolerated single dose was defined per protocol as 55-60 mg. This dose is above the equivalent
dose shown to have positive effects in mouse models of AD. There were no significant changes in laboratory or electrocardiogram
(ECG) parameters. ANAVEX®2-73 was well tolerated below the 55-60 mg dose with only mild adverse events in some
subjects. Observed adverse events at doses above the maximum tolerated single dose included headache and dizziness, which were
moderate in severity and reversible. These side effects are often seen with drugs that target CNS conditions, including AD.
In
December 2014, a Phase 2a clinical trial was initiated for ANAVEX®2-73, for the treatment of Alzheimer’s
disease. The open-label randomized trial was designed to assess the safety and exploratory efficacy of ANAVEX®2-73
in 32 patients with mild-to-moderate Alzheimer’s disease. ANAVEX®2-73 targets sigma-1 and muscarinic receptors,
which have been shown in preclinical studies to reduce stress levels in the brain believed to restore cellular homeostasis and
to reverse the pathological hallmarks observed in Alzheimer’s disease. The Phase 2a study met both primary and secondary
objectives of the study.
In
July 2018, we presented the results of a genomic DNA and RNA evaluation of the participants in the Phase 2a study. More than 33,000
genes were analyzed using unbiased, data driven, machine learning, artificial intelligence (AI) system for analyzing DNA &
RNA data in patients exposed to ANAVEX®2-73. The analysis identified genetic variants that impacted response to
ANAVEX®2-73, among them variants related to the Sigma-1 receptor (SIGMAR1), the target for ANAVEX®2-73.
Results showed that study participants with the common SIGMAR1 wild type gene variant, which is about 80 percent of the population
worldwide, demonstrated improved cognitive (MMSE) and the functional (ADCS-ADL) scores. The results from this evaluation have
been used to establish a precision medicine approach in subsequent clinical trials, since these signatures can now be applied
to neurological indications tested in clinical studies with ANAVEX®2-73 including Alzheimer’s disease, Parkinson’s
disease dementia and Rett syndrome.
ANAVEX®2-73
data presented met prerequisite information in order to progress into a Phase 2b/3 placebo-controlled study. On July 2, 2018,
the Human Research Ethics Committee in Australia approved the initiation of our Phase 2b/3, double-blind, randomized, placebo-controlled
48-week safety and efficacy trial of ANAVEX®2-73 for the treatment of early Alzheimer’s disease. Clinical
trial sites in Canada, the United Kingdom, the Netherlands and Germany were also added. This Phase 2b/3 study design incorporates inclusion of
genomic precision medicine biomarkers identified in the ANAVEX®2-73 Phase 2a study. The Phase 2b/3 study, which
is expected to enroll approximately 450 patients, randomized 1:1:1 to either two different ANAVEX®2-73 doses or
placebo, commenced in October 2018.
Preclinical
data also validates ANAVEX®2-73 as a prospective platform drug for other neurodegenerative diseases beyond Alzheimer’s
disease, Parkinson’s disease or Rett syndrome, more specifically, epilepsy, infantile spasms, Fragile X syndrome, Angelman
syndrome, multiple sclerosis and, more recently, tuberous sclerosis complex (TSC). ANAVEX®2-73 demonstrated significant
improvements in all of these indications in the respective preclinical animal models.
In
a study sponsored by the Foundation for Angelman Syndrome, ANAVEX®2-73 was assessed in a mouse model for the development
of audiogenic seizures. The results indicated that ANAVEX®2-73 administration significantly reduced audiogenic-induced
seizures. In a study sponsored by FRAXA Research Foundation regarding Fragile X syndrome, data demonstrated that ANAVEX®2-73
restored hippocampal brain-derived neurotrophic factor (BDNF) expression to normal levels. BDNF under-expression has been observed
in many neurodevelopmental and neurodegenerative pathologies. BDNF signaling promotes maturation of both excitatory and inhibitory
synapses. ANAVEX®2-73 normalization of BDNF expression could be a contributing factor for the positive data observed
in both neurodevelopmental and neurodegenerative disorders like Angelman and Fragile X syndromes.
Preclinical
data presented also indicates that ANAVEX®2-73 demonstrates protective effects of mitochondrial enzyme complexes
during pathological conditions, which, if impaired, are believed to play a role in the pathogenesis of neurodegenerative and neurodevelopmental
diseases.
Preclinical
data on ANAVEX®2-73 related to multiple sclerosis indicates that ANAVEX®2-73 may promote remyelination
in multiple sclerosis disease. Further, data also demonstrates that ANAVEX®2-73 provides protection for oligodendrocytes
(“OL’s”) and oligodendrocyte precursor cells (“OPC’s”), as well as central nervous system
neurons in addition to helping repair by increasing OPC proliferation and maturation in tissue culture.
In
March 2018, we presented preclinical data of ANAVEX®2-73 in a genetic mouse model of tuberous sclerosis complex
(“TSC”). TSC is a rare genetic disorder characterized by the growth of numerous benign tumors in many parts of the
body with a high incidence of seizures. The new preclinical data demonstrates that treatment with ANAVEX®2-73 significantly
increases survival and reduces seizures.
ANAVEX®3-71
ANAVEX®3-71
is a clinical drug candidate with a novel mechanism of action via sigma-1 receptor activation and M1 muscarinic allosteric modulation,
which has been shown to enhance neuroprotection and cognition in Alzheimer’s disease models. ANAVEX®3-71
is a CNS-penetrable potential disease modifying treatment for cognitive impairments. It is highly effective in very small doses
against the major Alzheimer’s hallmarks in transgenic (3xTg-AD) mice, including cognitive deficits, amyloid and tau pathologies,
and also has beneficial effects on inflammation and mitochondrial dysfunctions. ANAVEX®3-71 indicates extensive
therapeutic advantages in Alzheimer’s and other protein-aggregation-related diseases given its ability to enhance neuroprotection
and cognition via sigma-1 receptor activation and M1 muscarinic allosteric modulation.
A
preclinical study examined the response of ANAVEX®3-71 in aged transgenic animal models and showed a significant
reduction in the rate of cognitive deficit, amyloid beta pathology and inflammation with the administration of ANAVEX 3-71. In
April 2016, the FDA granted Orphan Drug Designation to ANAVEX®3-71 for the treatment of Frontotemporal dementia
(FTD).
During
pathological conditions ANAVEX®3-71 demonstrated the formation of new synapses between neurons (synaptogenesis)
without causing an abnormal increase in the number of astrocytes. In neurodegenerative diseases such as Alzheimer’s and
Parkinson’s disease, synaptogenesis is believed to be impaired. Additional preclinical data presented also indicates that
in addition to reducing oxidative stress, ANAVEX®3-71 demonstrates protective effects of mitochondrial enzyme complexes
during pathological conditions, which, if impaired, are believed to play a role in the pathogenesis of neurodegenerative and neurodevelopmental
diseases.
In
July 2020, we commenced the first Phase 1 clinical trial of ANAVEX®3-71, with focus on the treatment of Frontotemporal
Dementia (FTD) and other dementia indications with unmet medical need. The study
is more fully described above under Clinical Studies Overview – Frontotemporal Dementia.
ANAVEX®1-41
ANAVEX®1-41
is a sigma-1 receptor agonist. Pre-clinical tests revealed significant neuroprotective benefits (i.e., protects nerve cells from
degeneration or death) through the modulation of endoplasmic reticulum, mitochondrial and oxidative stress, which damages and
impairs cell viability. In addition, in animal models, ANAVEX®1-41 prevented the expression of caspase-3, an enzyme
that plays a key role in apoptosis (programmed cell death) and loss of cells in the hippocampus, the part of the brain that regulates
learning, emotion and memory. These activities involve both muscarinic and sigma-1 receptor systems through a novel mechanism
of action.
Preclinical
data presented also indicates that ANAVEX®1-41 demonstrates protective effects of mitochondrial enzyme complexes
during pathological conditions, which, if impaired, are believed to play a role in the pathogenesis of neurodegenerative and neurodevelopmental
diseases.
ANAVEX®1066
ANAVEX®1066,
a mixed sigma-1/sigma-2 ligand is designed for the potential treatment of neuropathic and visceral pain. ANAVEX®1066
was tested in two preclinical models of neuropathic and visceral pain that have been extensively validated in rats. In the chronic
constriction injury model of neuropathic pain, a single oral administration of ANAVEX®1066 dose-dependently restored
the nociceptive threshold in the affected paw to normal levels while leaving the contralateral healthy paw unchanged. Efficacy
was rapid and remained significant for two hours. In a model of visceral pain, chronic colonic hypersensitivity was induced by
injection of an inflammatory agent directly into the colon and a single oral administration of ANAVEX®1066 returned
the nociceptive threshold to control levels in a dose-dependent manner. Companion studies in rats demonstrated the lack of any
effects on normal gastrointestinal transit with ANAVEX®1066 and a favorable safety profile in a battery of behavioral
measures.
ANAVEX®1037
ANAVEX®1037
is designed for the treatment of prostate and pancreatic cancer. It is a low molecular weight, synthetic compound exhibiting high
affinity for sigma-1 receptors at nanomolar levels and moderate affinity for sigma-2 receptors and sodium channels at micromolar
levels. In advanced pre-clinical studies, this compound revealed antitumor potential. It has also been shown to selectively kill
human cancer cells without affecting normal/healthy cells and also to significantly suppress tumor growth in immune-deficient
mice models. Scientific publications highlight the possibility that these ligands may stop tumor growth and induce selective cell
death in various tumor cell lines. Sigma receptors are highly expressed in different tumor cell types. Binding by appropriate
sigma-1 and/or sigma-2 ligands can induce selective apoptosis. In addition, through tumor cell membrane reorganization and interactions
with ion channels, our drug candidates may play an important role in inhibiting the processes of metastasis (spreading of cancer
cells from the original site to other parts of the body), angiogenesis (the formation of new blood vessels) and tumor cell proliferation.
Our
compounds are in the pre-clinical and clinical testing stages of development, and there is no guarantee that the activity demonstrated
in pre-clinical models will be shown in human testing.
We
continue to identify and initiate discussions with potential strategic and commercial partners to most effectively advance our
programs and realize maximum shareholder value. Further, we may acquire or develop new intellectual property and assign, license,
or otherwise transfer our intellectual property to further our goals.
Our
Target Indications
We
have developed compounds with potential application to two broad categories and several specific indications. including:
Central
Nervous System Diseases
Alzheimer’s
disease – In 2020, an estimated 5.8 million Americans were suffering from Alzheimer’s disease. The Alzheimer’s
Association® estimates that by 2050, this number will rise to nearly 14 million Americans. Medications on the market
today treat only the symptoms of Alzheimer’s disease and do not have the ability to stop its onset or its progression. There
is an urgent and unmet need for both a disease modifying cure for Alzheimer’s disease as well as for better symptomatic
treatments.
Parkinson’s
disease – Parkinson’s disease is a progressive disease of the nervous system marked by tremors, muscular rigidity,
and slow, imprecise movement. It is associated with degeneration of the basal ganglia of the brain and a deficiency of the neurotransmitter
dopamine. Parkinson’s disease afflicts more than 10 million people worldwide, typically middle-aged and elderly people.
The Parkinson’s disease market is expected to expand to $3.2 billion by 2021, according to business intelligence provider
GBI Research.
Rett
syndrome - Rett syndrome is a rare X-linked genetic neurological and developmental disorder that affects the way the brain develops,
including protein transcription, which is altered and as a result leads to severe disruptions in neuronal homeostasis. It is considered
a rare, progressive neurodevelopmental disorder and is caused by a single mutation in the MECP2 gene. Because males have a different
chromosome combination from females, boys who have the genetic MECP2 mutation are affected in devastating ways. Most of them die
before birth or in early infancy. For females who survive infancy, Rett syndrome leads to severe impairments, affecting nearly
every aspect of the child’s life; severe mental retardation, their ability to speak, walk and eat, sleeping problems, seizures
and even the ability to breathe easily. Rett syndrome affects approximately 1 in every 10,000-15,000 females.
Depression
- Depression is a major cause of morbidity worldwide according to the World Health Organization. Pharmaceutical treatment for
depression is dominated by blockbuster brands, with the leading nine brands historically accounting for approximately 75% of total
sales. However, the dominance of the leading brands is waning, largely due to the effects of patent expiration and generic competition.
Epilepsy
- Epilepsy is a common chronic neurological disorder characterized by recurrent unprovoked seizures. These seizures are transient
signs and/or symptoms of abnormal, excessive or synchronous neuronal activity in the brain. According to the Centers for Disease
Control and Prevention, in 2015 epilepsy affected 3.4 million Americans. Today, epilepsy is often controlled, but not cured, with
medication that is categorized as older traditional anti-epileptic drugs and second generation anti-epileptic drugs. Because epilepsy
afflicts sufferers in different ways, there is a need for drugs used in combination with both traditional anti-epileptic drugs
and second generation anti-epileptic drugs.
Neuropathic
Pain – We define neuralgia, or neuropathic pain, as pain that is not related to activation of pain receptor cells in any
part of the body. Neuralgia is more difficult to treat than some other types of pain because it does not respond well to normal
pain medications. Special medications have become more specific to neuralgia and typically fall under the category of membrane
stabilizing drugs or antidepressants.
Cancer
Malignant
Melanoma - Predominantly a skin cancer, malignant melanoma can also occur in melanocytes found in the bowel and the eye. Malignant
melanoma accounts for 75% of all deaths associated with skin cancer. The treatment includes surgical removal of the tumor, adjuvant
treatment, chemo and immunotherapy, or radiation therapy. According to IMS Health the worldwide malignant melanoma market is expected
to grow to $4.4 billion by 2022.
Prostate
Cancer – Specific to men, prostate cancer is a form of cancer that develops in the prostate, a gland in the male reproductive
system. The cancer cells may metastasize from the prostate to other parts of the body, particularly the bones and lymph nodes.
Drug therapeutics for prostate cancer are expected to increase to nearly $13.5 billion in 2024 according to Datamonitor Healthcare.
Pancreatic
Cancer - Pancreatic cancer is a malignant neoplasm of the pancreas. In the United States, approximately 55,000 new cases of pancreatic
cancer will be diagnosed this year and approximately 44,000 patients will die as a result of their cancer, according to the American
Cancer Society. Sales predictions by GBI Research forecast that the market for the pharmaceutical treatment of pancreatic cancer
in the United States and five largest European countries will increase to $2.9 billion by 2021.
Competition
The
pharmaceutical industry is intensely competitive.
At
this time, our competitors are other biomedical development companies that are trying to discover and develop compounds to be
used in the treatment of Alzheimer’s disease and other CNS diseases, and those companies already doing so. Those companies
include Biogen (NASDAQ:BIIB), Pfizer Inc. (NYSE:PFE), Abbvie Plc (NYSE:ABBV), Novartis AG (NYSE:NVS), GlaxoSmithKline Plc (NYSE:GSK),
Merck & Co. Inc. (NYSE:MRK), Eli Lilly & Co. (NYSE: LLY), Johnson & Johnson (NYSE:JNJ) and Roche Holding AG (VTX:ROG).
For additional discussion of the risks related to competition, see Item 1A “Risk Factors.”
