- Topline data identifies maximum tolerated dose from Phase
IIA multiple ascending dose study as assessed by an independent
safety review committee
- Identified dose is unlikely to require lithium therapeutic
drug monitoring
- Alzamend plans two Phase II clinical trials to investigate
the safety and efficacy of AL001 for patients with mild to moderate
Alzheimer’s disease
- Investigational new drug applications to be filed for AL001
for treatment of bipolar disorder, major depressive disorder and
post-traumatic stress disorder
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 (“BPD”), major
depressive disorder (“MDD”) and post-traumatic stress
disorder (“PTSD”), today announced that it has successfully
identified a maximum tolerated dose (“MTD”) for development
of AL001 from a multiple-ascending dose study as assessed by an
independent safety review committee. This dose, providing lithium
at a lithium carbonate equivalent dose of 240 mg 3-times daily
(“TID”), is designed to be unlikely to require lithium
therapeutic drug monitoring (“TDM”). Also, this MTD is risk
mitigated for the purpose of treating fragile populations, such as
Alzheimer’s patients.
Lithium is a commonly prescribed drug for manic episodes in BPD
type 1 as well as maintenance therapy of BPD in patients with a
history of a manic episode. Lithium is also prescribed off-label
for MDD, BPD and treatment of PTSD, among other disorders. Lithium
was the first mood stabilizer approved by the United States Food
and Drug Administration (“FDA”) and is still a first-line
treatment option (considered the “gold standard”) but is
underutilized perhaps because of the need for TDM. 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
BPD when using lithium salts. Excursions above this range can be
toxic, and below can impair effectiveness.
AL001 is a novel lithium-delivery system; it is a
lithium-salicylate-L-proline engineered ionic cocrystal under
development as an oral treatment for patients with
neurodegenerative, neurological and neuropsychiatric conditions.
AL001 has the potential to deliver benefits of marketed lithium
salts while mitigating or avoiding currently experienced toxicities
associated with lithium. These results identified a safe and
appropriate dose to explore the potential for AL001 to distribute
more lithium to the brain but at lower systemic exposure, resulting
in an improved safety profile compared to currently marketed
lithium salts, thereby avoiding the disadvantages of currently
approved lithium salts.
“This is excellent news for the 43+ million Americans afflicted
with Alzheimer’s, BPD, MDD and PTSD. The data support AL001 safety
and tolerability and the potential for AL001 to provide a
next-generation lithium therapy that does not require TDM. This can
positively impact patient health and safety,” said Stephan Jackman,
Chief Executive Officer of Alzamend. “We look forward to further
evaluating AL001 in two Phase II clinical trials for patients with
mild to moderate Alzheimer’s, of which we anticipate initiating
both by the first quarter of 2024, and exploring the potential for
AL001 for patients suffering from BPD, MDD and PTSD by submitting
investigational new drug applications to the FDA for these
indications by the end of 2023. We appreciate the extraordinary
efforts of our colleagues and partners to identify a rigorously
determined MTD from this multiple-ascending dose study.”
About AL001 Phase IIA Study
The Phase IIA study evaluated the safety and tolerability of
AL001 under multiple-dose, steady‑state conditions. It determined
the MTD in patients diagnosed with mild to moderate Alzheimer’s
disease and in healthy non-elderly and elderly subjects with
adequate renal function. Lithium has been well-characterized for
safety and is approved/marketed in multiple formulations for BPD.
Lithium dosing for the multiple-ascending dose cohorts consisted of
fractions of a usual dose for treatment of BPD. In each cohort,
consisting of 6 active and 2 placebo subjects (as per
randomization), multiple ascending doses were administered TID for
14 days, up to tolerability/safety limits. The safety profile was
demonstrated to be benign at all dose levels, and so the selected
dose level chosen for further development was based on avoidance of
plasma drug concentrations associated in the medical literature
with possible toxicity.
Based on the results from this study, Alzamend plans to initiate
two future clinical trials at this MTD to determine relative
increased lithium levels in the brain compared to a marketed
lithium salt for Alzheimer’s, BPD, MDD and PTSD, based on published
mouse studies that predict that lithium can be given at lower doses
for equivalent therapeutic benefit when treating with AL001. For
example, the goal is to replace a 300 mg TID lithium carbonate dose
for treatment of BPD with a 240 mg TID AL001 lithium equivalent,
which represents a daily decrease of 20% of lithium given to a
patient.
About Alzamend Neuro
Alzamend is an early clinical-stage biopharmaceutical company
focused on developing novel products for the treatment of
Alzheimer’s, BPD, 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, proline and salicylate, and
AL002 - 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.
