Item 7.01 |
Regulation FD Disclosure. |
On May 17, 2023, Tonix Pharmaceuticals
Holding Corp. (the “Company”) announced the molecular mechanism of action of tianeptine, the active ingredient of the Company’s
TNX-601 ER (tianeptine hemioxalate extended-release tablets) product candidate, currently in Phase 2 clinical development for the treatment
of major depressive disorder (“MDD”). A copy of the press release which discusses this matter is furnished hereto as Exhibit
99.01, and incorporated herein by reference.
The Company updated its TNX-601
presentation, which it intends to place on its website and which may contain nonpublic information. A copy of the presentation is filed
as Exhibit 99.02 hereto and incorporated herein by reference.
The information in this Item 7.01
of this Current Report on Form 8-K, including Exhibits 99.01 and 99.02 attached hereto, shall not be deemed “filed” for
purposes of Section 18 of the United States Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the
liabilities of that section, nor shall they be deemed incorporated by reference in any filing under the United States Securities Act of
1933 or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.
On May 17, 2023, the Company announced
the molecular mechanism of action of tianeptine, the active ingredient of TNX-601 ER, currently in Phase 2 clinical development for the
treatment of MDD. Based on pharmacology and medicinal chemistry experiments, scientists at the Company have established that tianeptine
is an agonist for the nuclear peroxisome proliferator-activated receptor (“PPAR”) isoforms PPAR-β/δ and PPAR-γ,
and tianeptine’s effects on these PPAR isoforms account for its ability to induce neuroplasticity in cultured neurons. The findings
upset a long-held belief that the only way to restore the connectivity of neurons damaged in the state of depression was to increase the
synaptic levels or activity of neurotransmitters such as the monoamines serotonin, norepinephrine, and dopamine. The new findings show
that selective activation of nuclear PPAR-β/δ and PPAR-γ in neurons and supporting glia appears to be a more direct mechanism
to achieve the goal of restoring neuronal connectivity, or neuroplasticity. Drugs that restore neuroplasticity are called plastogens.
Consequently, tianeptine is a plastogen that acts directly on nuclear receptors that regulate gene expression in neurons and microglia.
The new research provides clarity
on why tianeptine does not cause sexual dysfunction, weight gain, or several other treatment-limiting toxicities associated with traditional
antidepressants. Tianeptine treats depression by activating select nuclear PPAR isoforms, and has little to do with monoaminergic neurotransmitters,
which are known to be implicated in the most frequently cited side effects of most marketed antidepressants. Key experiments were performed
by scientists at the Company’s Research and Development Center in Frederick, Maryland.
In animal models, tianeptine restores
neuroplasticity and reverses stress-induced impairments through activation of select nuclear PPAR isoforms without modulating synaptic
monoamine neurotransmitters, mimicking naturally occurring polyunsaturated fatty acid in binding to PPARs.
The Company believes that the
proposed mechanism is consistent with the clinical effects of tianeptine in promoting cognition in Alzheimer’s disease, Parkinson’s
disease and bipolar disorder, and is considering the development TNX-601 ER as a treatment for these and other conditions.
The new findings about tianeptine’s
mechanism dispel the notion that tianeptine’s weak µ-opioid receptor activity was central to its mechanism of treating depression
and indicate that there is no connection between tianeptine’s neuroplastic effects on cultured neurons and its weak µ-opioid
receptor agonism. The Company has identified a new chemical entity related to tianeptine, TNX-4300, that restores neuroplasticity in cultured
neurons and is free from µ-opioid receptor activity. The Company intends to submit data supporting tianeptine’s mechanism
of action for presentation at upcoming scientific conferences and for publication in peer reviewed journals.
