On September 21, 2023, Tonix Pharmaceuticals Holding Corp. (the “Company”) announced a poster presentation showing research results for the Company’s mTNX-1700 (murine trefoil factor family member 2- murine serum albumin, or mTFF2-MSA) product candidate (the “Poster”) at the Seventh International Cancer Immunotherapy Conference 2023 (“CICON23”): Translating Science into Survival, being held September 20-23, 2023. A copy of the press release which discusses this matter is furnished hereto as Exhibit 99.01, and incorporated herein by reference. A copy of the Poster is furnished hereto as Exhibit 99.02 and incorporated herein by reference.

The Company updated its TNX-102 SL (cyclobenzaprine HCl sublingual tablet) product candidate presentation, which the Company intends to place on its website, which may contain nonpublic information. A copy of the presentation is filed as Exhibit 99.03 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, 99.02 and 99.03 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 September 21, 2023, the Company announced the presentation of the Poster CICON23. The Poster, entitled, “mTFF2-MSA (mTNX-1700) Suppresses Tumor Growth and Increases Survival in Anti-PD-1 Treated CT26.WT Subcutaneous and CT26-Luciferase Orthotopic Syngeneic Colorectal Cancer Models by Targeting MDSCs in BALB/C Mice,” includes data demonstrating that mTNX-1700, a novel fusion protein, has single agent activity and can improve on the therapeutic effects of anti-PD-1 in treating syngeneic mouse models of advanced colorectal cancer. In two models, mTNX-1700 increased survival rates and suppresses tumor growth. Additive tumor growth suppression effects were observed when mTNX-1700 and anti-PD-1 were used in combination. The Company believes that the data demonstrate the potential of TNX-1700 in treating cancer both as a single agent and in combination with other immuno-oncology drugs, particularly anti-PD-1, and highlight how mTNX-1700 targets myeloid-derived suppressor cells as a novel mechanism to treat cancer.
