Item 7.01 Regulation FD Disclosure.

 

On November 15, 2023, Tonix Pharmaceuticals Holding Corp. (the “Company”) announced the completion of the clinical phase of the Phase 3 registration-quality, double-blind, placebo-controlled RESILIENT study of its TNX-102 SL (cyclobenzaprine HCl sublingual tablets) 5.6 mg product candidate for the management of fibromyalgia. 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 investor presentation, which is used to conduct meetings with investors, stockholders and analysts and at investor conferences, and which the Company intends to place on its website, which may contain nonpublic information. A copy of the presentation is filed as Exhibit 99.02 hereto and incorporated herein by reference. The Company also updated its TNX-1900 and TNX-102 SL product candidate presentations, which it intends to place on its website and which may contain nonpublic information. Copies of the presentations are filed as Exhibits 99.03 and 99.04 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, 99.03 and 99.04 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 15, 2023, the Company announced the completion of the clinical phase of the Phase 3 RESILIENT study of TNX-102 SL for the management of fibromyalgia. A total of 457 patients were enrolled in this multi-site study in the U.S. Topline results are expected in late December 2023. If successful, the Company believes that the RESILIENT study may be the final, well-controlled efficacy trial required for submission of a New Drug Application for approval by the U.S. Food and Drug Administration. The preliminary unaudited rate of adverse-event (“AE”) related discontinuations in the RESILIENT study was 4.8%, which compares favorably to the blinded AE-related discontinuation rates in the two previous Phase 3 trials of TNX-102 SL: 6.0% in the RELIEF trial, which achieved statistical significance on the primary endpoint (p=0.010), and 10.7% in the RALLY trial, which was stopped at the interim analysis. The Company believes that an unexpectedly high rate of AE-related discontinuations in the RALLY trial contributed to missing its primary endpoint, as the study was conducted during the Delta wave of the COVID pandemic, which we may have contributed to patient discontinuations. AE-related discontinuations are treated as negative outcomes in the ‘missing data’ multiple imputation approach that is part of the analysis of the primary endpoint.

  

The Company is actively exploring strategic partnerships and out-licensing opportunities for certain of its product candidates, including TNX-1500.

Tonix Pharmaceuticals Completes Clinical Stage of Phase 3 RESILIENT Study of TNX-102 SL for the Management of Fibromyalgia

Topline results expected late December 2023

RESILIENT is expected to be the final efficacy trial required for submission of a New Drug Application to FDA; first successful Phase 3 trial, RELIEF, achieved statistical significance (p=0.010),

Preliminary unaudited rate of adverse-event (AE) related discontinuations in the RESILIENT study was 4.8% which compares favorably with prior studies: RELIEF 6.0% and RALLY 10.7%

TNX-102 SL is a centrally acting, non-opioid analgesic

CHATHAM, N.J., November 15, 2023 (GLOBE NEWSWIRE) – Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced the completion of the clinical phase of the Phase 3 registration-quality, double-blind, placebo-controlled RESILIENT1 study of TNX-102 SL2 (cyclobenzaprine HCl sublingual tablets) 5.6 mg for the management of fibromyalgia. A total of 457 patients were enrolled in this multi-site study in the U.S. Topline results are expected in late December 2023. If successful, it is expected to be the final, well-controlled efficacy trial required for submission of a New Drug Application (NDA) for approval by the U.S. Food and Drug Administration (FDA).

“There are an estimated 6-12 million individuals in the U.S. suffering from this debilitating condition, most of whom are women,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “TNX-102 SL is a centrally-acting, non-opioid analgesic bedtime medication designed to be used on a chronic basis for the management of fibromyalgia. We believe TNX-102 SL works by improving sleep quality, which leads to improvement of other symptoms. In previous studies, TNX-102 SL showed broad coverage across the symptoms of fibromyalgia, including chronic widespread pain, fatigue and sleep disturbance.”

“The preliminary unaudited rate of adverse-event (AE) related discontinuations in the RESILIENT study was 4.8%,” said Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals. “This compares favorably to the blinded AE-related discontinuation rates in our two previous Phase 3 trials: 6.0% in RELIEF which achieved statistical significance on the primary endpoint (p=0.010), and 10.7% in RALLY which was stopped at the interim analysis. We later learned that an unexpectedly high rate of AE-related discontinuations in RALLY contributed to missing the primary endpoint. The study was conducted during the Delta wave of the COVID pandemic, which we believe may have contributed to patient discontinuations. AE-related discontinuations are treated as negative outcomes in the ‘missing data’ multiple imputation approach that is part of the analysis of the primary endpoint.”

In December 2020, Tonix reported positive results from the first Phase 3 RELIEF study of TNX-102 SL 5.6 mg for the management of fibromyalgia.3 TNX-102 SL met its pre-specified primary endpoint in the Phase 3 RELIEF trial, significantly reducing daily pain compared to placebo (p=0.010) in participants with fibromyalgia. Also, when the primary endpoint was analyzed as a ≥30% pain responder analysis, there was a higher rate of responders to TNX-102 SL (47%) than to placebo (35%; p=0.006). TNX-102 SL at 5.6 mg also showed activity in key secondary endpoints, demonstrating improvements in sleep quality, mitigation of fatigue, and fibromyalgia-specific global symptomatic and functional recovery. TNX-102 SL was generally safe and well tolerated in patients with fibromyalgia, with overall adverse event profile comparable to prior fibromyalgia studies. The most common treatment-emergent adverse events were oral hypoesthesia, oral paresthesia, and product taste abnormal.

About the Phase 3 RESILIENT Study

The RESILIENT study is a double-blind, randomized, placebo-controlled trial designed to evaluate the efficacy and safety of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) in the management of fibromyalgia. The two-arm trial randomized 457 participants across 33 sites in the U.S. The first two weeks of treatment consist of a run-in period in which participants start on TNX-102 SL 2.8 mg (1 tablet) or placebo. Thereafter, all participants increase their dose to TNX-102 SL 5.6 mg (2 x 2.8 mg tablets) or two placebo tablets for the remaining 12 weeks. The primary endpoint is the daily diary pain severity score change from baseline to Week 14 (using the weekly averages of the daily numerical rating scale scores) for TNX-102 SL 5.6 mg vs. placebo, analyzed by mixed model repeated measures with multiple imputation.

For more information, see ClinicalTrials.gov Identifier: NCT05273749.

About Fibromyalgia

Fibromyalgia is a chronic pain disorder that is understood to result from amplified sensory and pain signaling within the central nervous system. Fibromyalgia afflicts an estimated 6-12 million adults in the U.S., approximately 90% of whom are women. Symptoms of fibromyalgia include chronic widespread pain, nonrestorative sleep, fatigue, and morning stiffness. Other associated symptoms include cognitive dysfunction and mood disturbances, including anxiety and depression. Individuals suffering from fibromyalgia struggle with their daily activities, have impaired quality of life, and frequently are disabled. Physicians and patients report common dissatisfaction with currently marketed products.

About TNX-102 SL

TNX-102 SL is a patented sublingual tablet formulation of cyclobenzaprine hydrochloride which provides rapid transmucosal absorption and reduced production of a long half-life active metabolite, norcyclobenzaprine, due to bypass of first-pass hepatic metabolism. As a multifunctional agent with potent binding and antagonist activities at the 5-HT2A-serotonergic, α1-adrenergic, H1-histaminergic, and M1-muscarinic receptors, TNX-102 SL is in development as a daily bedtime treatment for fibromyalgia, Long COVID (formally known as post-acute sequelae of COVID-19 [PASC]), alcohol use disorder and agitation in Alzheimer’s disease. The United States Patent and Trademark Office (USPTO) issued United States Patent No. 9636408 in May 2017, Patent No. 9956188 in May 2018, Patent No. 10117936 in November 2018, Patent No. 10,357,465 in July 2019, and Patent No. 10736859 in August 2020. The Protectic™ protective eutectic and Angstro-Technology™ formulation claimed in the patent are important elements of Tonix’s proprietary TNX-102 SL composition. These patents are expected to provide TNX-102 SL, upon NDA approval, with U.S. market exclusivity until 2034/2035.

4 © 2023 Tonix Pharmaceuticals Holding Corp. CNS PORTFOLIO TNX - 1900 for the Treatment of Migraine and Craniofacial Pain: Overview Novel intranasal oxytocin formulation being developed as a prophylactic treatment for chronic migraine • Based on a propriety formulation of oxytocin*, a naturally occurring human hormone that acts as a neurotransmitter in the brain Clinical and preliminary research has shown that low oxytocin levels in the body can lead to increase in headache frequency, and that increased oxytocin levels can relieve headaches • Certain other chronic pain conditions are also associated with decreased oxytocin levels Oxytocin when delivered via the nasal route, results in enhanced binding of oxytocin to receptors on neurons in the trigeminal system, inhibiting transmission of pain signals Intranasal oxytocin has been shown in animals that it can also block CGRP release, a pathway known to be critical to the pathogenesis of migraine attacks. * Oxytocin is approved by the U.S. Food and Drug Administration (FDA) as Pitocin ® , an intravenous infusion or intramuscular injection drug, for use in pregnant women to induce labor. An intranasal form of oxytocin was marketed by Novartis to assist in nursing as Syntocinon ® , but the product was withdrawn and the New Drug Application (NDA) has been discontinued.

  


5 © 2023 Tonix Pharmaceuticals Holding Corp. CNS PORTFOLIO TNX - 1900 for the Treatment of Migraine: Mechanism of Action Preclinical research showed that nasally applied TNX - 1900 selectively inhibits the activity of trigeminal pain - sensing nerve cells and blocks the release of CGRP • TNX - 1900 is believed to interrupt pain signals at the trigeminal ganglia by suppressing electrical impulses, a potentially different activity than drugs that just block CGRP Migraine attacks are caused, in part, by the release of CGRP from pain - sensing nerve cells that are part of the trigeminal system • The CGRP binds to receptors on other nerve cells and starts a cascade of events that eventually results in a severe headache. This, in turn, reduces various kinds of trigeminal nerve associated pain and prevents CGRP from acting at receptors in the central nervous system that are involved in migraine. We believe targeted delivery of oxytocin could translate into selective blockade of CGRP release in the trigeminal ganglion and not throughout the body, which could be a potential safety advantage over systemic CGRP inhibition • In addition, daily dosing is more quickly reversible, in contrast to monthly or quarterly dosing, giving physicians and their patients greater control 6 © 2023 Tonix Pharmaceuticals Holding Corp.
