| Item 7.01. | Regulation FD Disclosure. |
On June 5, 2023, the Company announced
the presentation of data detailing the mechanism of action and pharmacokinetics of the Company’s TNX-601 ER (tianeptine hemioxalate
extended release) and TNX-4300 (estianeptine) product candidates. A copy of the press release which discusses this matter is furnished
hereto as Exhibit 99.01, and incorporated herein by reference. Copies of the presentation and poster which present the data are furnished
hereto as Exhibits 99.02 and 99.03, respectively, 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.
On June 5, 2023, the Company announced
the presentation of data detailing the mechanism of action and pharmacokinetics of TNX-601 ER (tianeptine hemioxalate extended release)
and TNX-4300 (estianeptine) at the American Society of Clinical Psychopharmacology. TNX-601 ER is being tested in a potentially pivotal
Phase 2 trial for the treatment of major depressive disorder (“MDD”) for which results of a preplanned interim analysis are
expected in the fourth quarter of 2023. TNX-4300 is in preclinical development for mood disorders, Alzheimer’s disease and Parkinson’s
disease. The active ingredient of both products is the (S)-isomer of tianeptine, which activates PPAR-β/δ, restores
neuroplasticity in neuronal tissue culture and lacks µ-opioid liability. In contrast, the (R)-isomer of tianeptine lacks
PPAR-β/δ activity and is an agonist at the µ-opioid receptor.
The findings demonstrate how the
pharmacokinetics of oral TNX-601 ER in humans differ from intraperitoneal (i.p.) tianeptine in mice. In humans, after an oral dose
of TNX-601 ER the half-life of tianeptine in the blood is approximately five to seven hours. In contrast, in mice after an i.p.
dose of tianeptine the half-life of tianeptine in the blood has been reported to be less than approximately 30 minutes, and the behavioral
effects appear dominated by the longer-lasting MC5 metabolite, which maintains µ-opioid receptor activity. The data also demonstrate
that the (R)-isomer of tianeptine is responsible for the decrease in immobility in the mouse forced swim test after i.p.
administration, which is consistent with previous reports that the effect of tianeptine on the forced swim test is a µ-opioid receptor-dependent
phenomenon. The Company believes these findings support the interpretation that the parent tianeptine and specifically, the (S)-isomer
of tianeptine, exert antidepressant effects in humans by interacting with PPAR-β/δ and PPAR-γ. The Company plans to test
single isomer TNX-4300 at a dose equivalent to 50% of the racemic dose, which is expected to provide equivalent exposure of (S)-tianeptine
as racemic tianeptine. Subsequently, the Company intends to test higher doses of (S)-tianeptine, as TNX-4300 lacks µ-opioid
receptor activity, but such studies will require additional non-clinical studies.
