Item 7.01 Regulation FD Disclosure.


On November 9, 2021, Tonix Pharmaceuticals Holding Corp. (the “Company”) issued a press release announcing the poster presentation (the “Poster”) of results from its Phase 1 clinical study of TNX-601 CR (tianeptine oxalate and naloxone controlled-release tablets) entitled “TNX-601 CR*: a Once-Daily Formulation of Tianeptine in Development for the Treatment of Major Depressive Disorder” at the CNS 2021 Summit. Copies of the Poster and press release which discusses this matter are furnished hereto as Exhibits 99.01 and 99.02, respectively, 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.


Item 8.01. Other Events.


On November 8, 2021, the Company presented the Poster of results from its open-label, Phase 1 clinical study of TNX-601 CR (tianeptine oxalate and naloxone controlled-release tablets) for the treatment for major depressive disorder (“MDD”) and post-traumatic stress disorder and neurocognitive dysfunction associated with corticosteroid use. The poster provides data related to the Phase 1 pharmacokinetic study in healthy subjects that assessed several novel modified-release (“MR”) prototype formulations of tianeptine oxalate. The study showed that the selected TNX-601 MR1 demonstrated pharmacokinetics appropriate for once-daily dosing with minimal food effect, which is a potential treatment adherence advantage over three times per day dosing of immediate release tianeptine sodium. This MR prototype was selected in the development of the final formulation of TNX-601 CR as a once-daily treatment for MDD. The Company believes that these Phase 1 findings support its upcoming Phase 2 study of once-daily TNX-601 CR for MDD in the first half of 2022. Based on the Phase 1 results, the Company believes that with respect to plasma tianeptine and its primary metabolite, TNX-601 CR would meet the bioequivalence standard for daily dosing of these immediate release products. TNX-601 CR’s proposed mechanism of action is distinct from any antidepressant approved in the U.S for chronic or long-term use. The Phase 2 study design is expected to be randomized, double-blind, placebo-controlled, parallel group study to evaluate the efficacy and safety of TNX-601 CR monotherapy versus placebo in MDD. Treatment duration will be 6 weeks, preceded by up to 5 weeks in screening and followed by a 2-week safety follow-up period (total up to 13 weeks of participation). The Company plans to randomize approximately 260 individuals with MDD at a 1:1 ratio to two arms of 130 each for drug and placebo at approximately 25-30 US sites. The primary efficacy endpoint will be the change from Baseline to Week 6 in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score. Enrollment is estimated to start in the first half of 2022, pending Investigational New Drug Application clearance by the U.S. Food and Drug Administration.
