Item 7.01 Regulation FD Disclosure.

 

On May 23, 2023, Tonix Pharmaceuticals Holding Corp. (the “Company”) announced the discovery by Company scientists of the isolation and functional characterization of the two mirror image isomers of racemic tianeptine, which is marketed ex-U.S. as a treatment for 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 information in this Item 7.01 of this Current Report on Form 8-K, including Exhibit 99.01 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.

 

Item 8.01.Other Events.

 

On May 23, 2023, the Company announced the discovery by its scientists of the isolation and functional characterization of the two mirror image isomers of racemic tianeptine. Company scientists discovered that the (S)-isomer of tianeptine activates PPAR-β/δ, restores neuroplasticity in neuronal tissue culture and is free of µ-opioid receptor activity. In contrast, (R)-tianeptine activates the µ-opioid receptor and lacks PPAR-β/δ activity. Based on these discoveries, the Company has begun pre-clinical development of its (S)-isomer, TNX-4300 (estianeptine) product candidate as a treatment for MDD, bipolar disorder, Alzheimer’s Disease and Parkinson’s Disease. Based on this discovery, the Company believes that the (S)-isomer is responsible for tianeptine’s activity on PPAR-β/δ and restoring neuroplasticity, and the (R)-isomer for its off-target activity on the µ-opioid receptor. The scientists isolated and characterized the (S)-isomer, now known as TNX-4300 and under development for psychiatric and neurological diseases.

 

The Company expects that its ongoing work on racemic tianeptine in depression may inform and potentially accelerate the development of TNX-4300. Although the dose of tianeptine for treating depression is well-established from racemic studies, the dose range for treating neurological diseases is not yet determined. Because TNX-4300 lacks the µ-opioid receptor activity, such effects will not limit the dosing of (S)-tianeptine for these other indications. (S)-tianeptine mimics naturally occurring polyunsaturated fatty acid ligands in binding PPAR-β/δ and PPAR-γ. (S)-tianeptine’s activation of nuclear PPAR-β/δ and PPAR-γ receptors appears to be a more direct mechanism to achieve the goal of restoring neuronal connectivity than current therapies. The PPAR-β/δ target is validated by prior work on agonists treating animal models of neurodegenerative and autoimmune diseases of the central nervous system and the concept that Alzheimer’s can be considered a form of diabetes that affects the central nervous system, or type-III diabetes. Key experiments were performed by scientists at the Company’s Research and Development Center in Frederick, Maryland. The Company plans to submit data supporting tianeptine’s mechanism of action for presentation at upcoming scientific conferences and for publication in peer reviewed journals.
