- Alzamend’s recently completed Phase IIA Study of AL001 in
Alzheimer’s patients and healthy subjects showed a benign safety
profile and identified a candidate dose that is unlikely to require
therapeutic drug monitoring
- Safety aspects of AL001 development may qualify for a
505(b)(2) NDA pathway for FDA approval
Alzamend Neuro, Inc. (Nasdaq: ALZN) (“Alzamend”), a
clinical-stage biopharmaceutical company focused on developing
novel products for the treatment of Alzheimer’s disease
(“Alzheimer’s”), bipolar disorder (“BD”), major
depressive disorder (“MDD”) and post-traumatic stress
disorder (“PTSD”), today announced that it has submitted an
investigational new drug (“IND”) application to the U.S.
Food and Drug Administration (“FDA”) for the initiation of
study AL001-PTSD01, a Phase IIA plasma/brain pharmacokinetics
clinical study of AL001 for treatment of patients with PTSD.
Although lithium products do not have an FDA-approved indication
for PTSD, case reports suggest that lithium treatment may be useful
for treating PTSD patients. In particular, treatment with low doses
(300–600 mg/day) of lithium carbonate have been reported to provide
effective treatment in reduction of inappropriate anger,
irritability, anxiety, and insomnia in those patients. The clinical
observation of mood swings beyond the normal range, but milder than
those associated with BD, reportedly suggested the presence of a
sub-threshold mood disorder in these PTSD patients. It has also
been proposed that treatment of trauma with lithium to forestall
the development of PTSD may be provided by pharmacological
induction of a mild transient amnesia.
Lithium was the first mood stabilizer approved by the FDA and is
still a first-line treatment option (considered the “gold
standard”) for BD but is underutilized perhaps because of the need
for therapeutic drug monitoring (“TDM”), that is, routine
monitoring of lithium drug levels in blood to help assure safety
and effectiveness. Lithium was the first drug that required TDM by
regulatory authorities in product labelling because the effective
and safe range of therapeutic drug blood concentrations is narrow
and well-defined for treatment of BD when using lithium salts.
Excursions above this range can be toxic, and below can impair
effectiveness.
AL001 is a novel lithium-delivery system that has the potential
to provide benefits of marketed lithium salts while mitigating or
avoiding currently experienced toxicities associated with lithium.
Results from Alzamend’s recently completed Phase IIA
multiple-ascending dose study of AL001 in Alzheimer’s patients and
healthy subjects identified a maximum tolerated dose
(“MTD”) that was vetted by an independent safety
review committee. This MTD is designed to distribute more lithium
to the brain but at lower systemic exposure, resulting in an
improved safety profile compared to currently marketed lithium
salts. This MTD was assessed to be unlikely to require TDM.
After receipt of a “study may proceed” communication from FDA,
Alzamend plans to initiate a Phase IIA study to characterize AL001
improvements of lithium levels in the brain compared to a marketed
lithium salt in PTSD patients. Alzamend anticipates that the new
drug application (“NDA”) development program for PTSD may,
for safety, qualify for a 505(b)(2) NDA pathway to FDA approval,
which can be available to new formulations of an approved drug.
“There are only two drugs approved by the FDA and currently
available in generic form for PTSD patients,” said Stephan Jackman,
Chief Executive Officer of Alzamend. “Being able to develop a
next-generation lithium product (AL001) that would not routinely
require TDM could positively impact the 9 million Americans
afflicted with PTSD. We look forward to providing more details
regarding the study’s timeline and market opportunity in the near
future.”
About Post-Traumatic Stress Disorder
PTSD is a mental and behavioral disorder that can develop
because of exposure to a traumatic event, such as sexual assault,
warfare, traffic collisions, child abuse, domestic violence, or
other threats on a person’s life (American Psychiatric Association
DSM-5-TR, 2020; Mayo Clinic, 2022). People who experience
interpersonal violence, such as rape, other sexual assaults, being
kidnapped, stalking, physical abuse by an intimate partner, and
incest or other forms of childhood sexual abuse, are more likely to
develop PTSD than those who experience non-assault-based trauma,
such as accidents and natural disasters. Symptoms may include
disturbing thoughts, feelings, or dreams related to the events,
mental or physical distress in response to trauma-related cues,
attempts to avoid trauma-related cues, alterations in the way a
person thinks and feels, and an increase in the fight-or-flight
response. These symptoms last for more than a month after the event
(American Psychiatric Association DSM-5-TR, 2020). A person with
PTSD is at a higher risk of suicide and intentional self-harm.
According to the NIH, about 3.6%, or roughly 9 million, adults in
the U.S. have PTSD in a given year, and 9% of people develop it at
some point in their life. In much of the rest of the world, rates
for a given year are between 0.5% and 1% of the population.

Alzamend Neuro is a clinical-stage biopharmaceutical company
focused on developing novel products for the treatment of
Alzheimer’s, BD, MDD and PTSD. Our mission is to rapidly develop
and market safe and effective treatments. Our current pipeline
consists of two novel therapeutic drug candidates, AL001 - a
patented ionic cocrystal technology delivering lithium via a
therapeutic combination of lithium, salicylate and L-proline, and
ALZN002 - a patented method using a mutant-peptide sensitized cell
as a cell-based therapeutic vaccine that seeks to restore the
ability of a patient’s immunological system to combat Alzheimer’s.
Both of our product candidates are licensed from the University of
South Florida Research Foundation, Inc. pursuant to royalty-bearing
exclusive worldwide licenses.
