Tonix Pharmaceuticals Reports Second Quarter 2020 Financial Results and Operational Highlights

Preclinical data for TNX-1800, a Vaccine Candidate to Protect Against COVID-19, Expected in Fourth Quarter 2020

Interim Analysis Results for Phase 3 RELIEF Trial of TNX-102 SL for the Management of Fibromyalgia Expected in September 2020

Topline Data for RELIEF Trial Expected in Fourth Quarter 2020

NEW YORK, Aug. 10, 2020 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals, Inc. Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a clinical-stage biopharmaceutical company, today announced financial results for the second quarter ended June 30, 2020, and provided an overview of recent operational highlights.

“The second quarter was highlighted by exciting progress for our lead immunology and central nervous system product candidates,” said Seth Lederman, M.D., President and Chief Executive Officer. “We expect to have the first data from animal studies of our lead COVID-19 vaccine candidate, TNX-1800, in the fourth quarter of this year. TNX-1800 is a live attenuated vaccine based on our proprietary horsepox vector system that carries a gene encoding the Spike protein from SARS-CoV-2, the virus that causes COVID-19. We have also continued to progress the Phase 3 RELIEF study of TNX-102 SL for fibromyalgia, having reached 50% enrollment in April and then completing enrollment in July, ahead of schedule. We look forward to interim data in September and topline results from the RELIEF study by the end of this year.”

Recent Highlights

Research and Development

COVID-19 vaccine candidate TNX-1800 (live attenuated vaccine based on horsepox virus vector) designed as a single-shot vaccine to elicit T cell immunity

• In June, Tonix announced an agreement with FUJIFILM Diosynth Biotechnologies to provide contract manufacturing and development services to support the manufacturing of TNX-1800 for clinical trial supply.
• Tonix expects small animal and non-human primate data from safety studies of TNX-1800 in COVID-19 models to measure safety and the immune response to the SARS-COV-2 Spike protein in the fourth quarter of 2020. In addition, we also expect data from non-human primate studies to measure efficacy in challenge studies using SARS-COV-2 in the fourth quarter.

COVID-19 research collaboration with Southern Research

• In June, Tonix announced a new collaboration with Southern Research to study T cell immune responses to SARS-CoV-2 in volunteers who have recovered from COVID-19 or remain asymptomatic after exposure to SARS-CoV-2. The results are expected to support the Company’s anticipated regulatory filings for TNX-1800, which is designed to express the SARS-CoV-2 Spike protein after vaccination.

COVID-19 research collaboration and option agreement with Columbia University

• In July, Tonix announced a partnership with Columbia University to apply precision medicine to the study of the T cell and antibody immune responses to COVID-19 in healthy volunteers who have recovered from COVID-19 or were exposed but remain asymptomatic. The research is designed to provide detailed immune responses to COVID-19 and to provide a foundation upon which to target vaccines and therapeutics to appropriate individuals by precision medicine.

COVID-19 vaccine candidates TNX-1800, TNX-1810, TNX-1820 and TNX-1830 (live attenuated vaccines based on horsepox virus vector) partnership with University of Alberta

• In May, Tonix announced a new collaboration with University of Alberta to develop three horsepox- based vaccines that are anticipated to elicit almost exclusively T cell immunity to proteins from SARS-COV-2 that are different from the Spike protein encoded by TNX-1800.

COVID-19 vaccine candidate TNX-2300 (live attenuated vaccine based on bovine parainfluenza virus) partnership with Kansas State University – new platform of a live attenuated vaccine designed to elicit T cell immunity by co-stimulation with CD40-ligand

• In July 2020, Tonix entered into a research and exclusive license option agreement with Kansas State University to develop a vaccine candidate for the prevention of COVID-19 that utilizes a novel live virus vaccine vector platform and the CD40-ligand, also known as CD154 or 5c8 antigen, to stimulate T cell immunity.

Plans to set up Advanced Development Center for process and analytical development

• In July, Tonix announced its intent to purchase an approximately 40,000 square foot facility in Massachusetts to use as laboratories to enable research and development functions associated with its expanding portfolio of immunological candidates, including vaccines for COVID-19 and biological products for other disorders.

Progress on TNX-102 SL (cyclobenzaprine HCl sublingual tablets) for Fibromyalgia

• In July, Tonix completed enrollment of approximately 470 participants in the Phase 3 RELIEF trial, ahead of schedule. The RELIEF study is a potential pivotal study of TNX-102 SL 5.6 mg taken daily at bedtime for the management of fibromyalgia.
• Tonix expects results from an interim analysis of the RELIEF study from the first 50 percent of randomized participants that are evaluable for efficacy in September 2020. The interim analysis will be conducted by an Independent Data Monitoring Committee which will review the unblinded data and make one of four recommendations: (1) stop the study for success; (2) continue the study as planned; (3) continue to enroll with a specified increase in the total number of participants in the full study; or (4) stop the study for futility.
• Tonix expects topline data for the RELIEF study in the fourth quarter of 2020 unless the interim Independent Data Monitoring Committee recommends an increase in the total number of participants.
• Tonix plans to initiate a second potentially pivotal Phase 3 trial, F306 or the RALLY study, to study TNX-102 SL for the management of fibromyalgia. Tonix expects enrollment to begin in the third quarter of this year. The trial design will be very similar to the ongoing Phase 3 RELIEF study. We expect the FDA to require two registration-quality clinical studies to support marketing approval.

Progress on TNX-102 SL (cyclobenzaprine HCl sublingual tablets) development for Alcohol Use Disorder

• In August, Tonix announced that it received FDA clearance of its IND for TNX-102 SL for the treatment of alcohol use disorder. This clearance supports the initiation of a Phase 2 proof-of-concept study.

Acquisition of potential migraine and craniofacial drug TNX-1900 (intranasal oxytocin)

• In June 2020, Tonix announced the acquisition of non-addictive migraine and pain treatment technologies from Trigemina, Inc., and the assumption of license for some of the technologies from Stanford University. The lead asset, TNX-1900, oxytocin solution for intranasal delivery, is a proprietary, patented enhanced formulation of nasal oxytocin, currently being studied as a candidate for prophylaxis of chronic migraine.
• Results from a preclinical study of TNX-1900 were posted at the American Academy of Neurology’s first-ever Sports Concussion Conference in June 2020. The presentation, titled “Intranasal (IN) Oxytocin Relieves Pain and Depressive Behavior in a Rodent Model of Mild Traumatic Brain Injury (TB),” included data from preclinical studies which investigated the efficacy of intranasal oxytocin in relieving pain and associated depressive behavior following mild traumatic brain injury.

Progress on oncology partnership with Columbia University on TNX-1700 (stabilized recombinant version of Trefoil Factor 2 (TFF2))

• Results from a preclinical study of TNX-1700, Tonix’s in-licensed asset from Columbia University, were presented in a poster at the American Association of Cancer Research Virtual Annual Meeting II held online June 22-24, 2020. The poster, titled “Stabilized recombinant trefoil factor 2 (TFF2-CTP) enhances anti-tumor activity of PD-1 blockage in mouse models of colorectal cancer,” included preclinical data investigating the role of PD-L1 in colorectal tumorigenesis and evaluating the utility of targeting myeloid-derived suppressor cells (MDSCs) with TNX-1700 in combination with PD-1 blockade in mouse models of colorectal cancer. The data show that anti-PD-1 monotherapy was unable to evoke anti-tumor immunity in this model of colorectal cancer, but TNX-1700 augmented the efficacy of anti-PD-1 therapy, showing greater anti-tumor activity in PD-L1-overexpressing mice. TNX-1700 is being developed for the treatment of gastric, colon and pancreatic cancers under a license from Columbia University.
