• Topline Results from Four CNS Clinical Trials Expected in the Third and Fourth Quarters of 2023
  
• Fibromyalgia Topline Results Expected in the Fourth Quarter of 2023 for Phase 3 Potentially NDA-Enabling Study of the Centrally-Acting Non-Opioid Analgesic TNX-102 SL
• Completed Strategic Acquisition of Two Marketed Acute Migraine Products: Zembrace^® SymTouch^® (sumatriptan injection) and Tosymra^® (sumatriptan nasal spray)

CHATHAM, N.J., Aug. 10, 2023 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company, today announced financial results for the second quarter ended June 30, 2023, and provided an overview of recent operational highlights.

“We have recently completed enrollment in four clinical trials for central nervous system (CNS) indications, representing our continuing progress towards bringing forth new treatments for serious CNS conditions that affect large patient populations,” said Seth Lederman, M.D., Chief Executive Officer of Tonix. “We look forward to data readouts before year-end 2023 for fibromyalgia, fibromyalgia-type Long COVID, chronic migraine, and depression. The topline results from the Phase 3 fibromyalgia trial are of particular importance because we believe the RESILIENT trial, if successful, will be the final efficacy trial required for submitting a New Drug Application (NDA) for approval by the U.S. Food and Drug Administration (FDA).”  

On June 30, 2023, Tonix completed the acquisition of two marketed products from Upsher-Smith Laboratories, LLC (Upsher-Smith): Zembrace^® SymTouch^® (sumatriptan injection) 3 mg and Tosymra^® (sumatriptan nasal spray) 10 mg. Zembrace SymTouch and Tosymra are both non-oral proprietary products indicated for the treatment of acute migraine with or without aura in adults. Zembrace SymTouch is the only branded sumatriptan autoinjector professionally promoted in the United States and is designed for ease of use and favorable tolerability with a low 3 mg dose. Tosymra is a novel intranasal sumatriptan product formulated with a permeation enhancer that provides rapid and efficient absorption of sumatriptan. Collectively, these products generated gross factory sales of approximately $30 million for the twelve months ended March 31, 2023. Zembrace SymTouch and Tosymra each may provide onset of migraine pain relief in as few as 10 minutes for some patients and currently have patent protection to 2036 and 2031, respectively.  

Seth Lederman continued, “The acquisition of these two marketed products is transformative for Tonix as we believe that we are on track to become a fully integrated pharmaceutical company and to expand our expertise in CNS disorders by interacting with health care providers and payers. The build out of our commercial capabilities is timely, given the potential 2025 launch of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) for fibromyalgia, if results from the RESILIENT trial are positive. The two marketed acute migraine products also align strongly with our clinical product candidate TNX-1900 (intranasal potentiated oxytocin), in development as a preventive medication in chronic migraineurs.”

“We plan to submit an IND to study TNX-2900 (intranasal potentiated oxytocin) in Prader-Willi syndrome, for which Orphan Drug Designation has already been granted by the FDA,” said Gregory Sullivan, M.D., Chief Medical Officer of Tonix Pharmaceuticals. “Academic collaborators have initiated enrollment in three Phase 2 investigator-initiated trials studying TNX-1900 (intranasal potentiated oxytocin). The trials in adolescent obesity and binge eating disorder at Massachusetts General Hospital (MGH) have the potential to expand the use of TNX-1900 to the treatment of disorders of appetite, eating behaviors and weight. The trial in social anxiety at University of Washington has the potential to expand the use of TNX-1900 to the treatment of disorders of social functioning.”

Dr. Lederman continued, “During the second quarter of 2023, we also announced the prioritization of our clinical stage CNS programs and de-prioritization of our COVID-19 vaccine and related therapeutic programs, as well as certain other preclinical programs in order to reallocate cash and resources. We also streamlined several CNS studies by eliminating interim analyses and reducing enrollment targets to ensure data readouts this year. We incurred a one-time cash outlay related to our acquisition of Zembrace SymTouch and Tosymra in the second quarter.”

Central Nervous System (CNS) Pipeline

TNX-102 SL (cyclobenzaprine HCl sublingual tablets): once-daily at bedtime small molecule for the management of fibromyalgia (FM) – centrally-acting, non-opioid analgesic.

• In August 2023, the Company announced that it completed enrollment of its potentially confirmatory Phase 3 RESILIENT trial of TNX-102 SL (cyclobenzaprine HCl sublingual tablets) 5.6 mg in fibromyalgia. A total of 457 participants were randomized in the trial, which, if successful, may serve as the final, well-controlled efficacy trial required for submission of an NDA for approval by the FDA. RESILIENT is a registration-quality, double-blind, placebo-controlled study.
• Topline results from the RESILIENT trial are expected in the fourth quarter of 2023

TNX-102 SL for the treatment of Fibromyalgia-Type Long COVID, also known as Post-Acute Sequelae of COVID-19 (PASC)

• In August 2023, the Company announced it completed the clinical phase of the PREVAIL study, a Phase 2 proof-of-concept study of TNX-102 SL for fibromyalgia-type Long COVID, as the last patient completed their final study visit. PREVAIL is a registration-quality, double-blind, placebo-controlled study.
• Topline results from the PREVAIL Phase 2 trial are expected in the third quarter of 2023.

TNX-1900 (intranasal potentiated oxytocin): small peptide for migraine, craniofacial pain, social anxiety disorder, insulin resistance and related disorders, and adolescent obesity and binge eating disorder

• Tonix has developed a formulation of intranasal oxytocin that contains magnesium (Mg2+) which is believed to potentiate the effects of oxytocin and may address the “inverted U” dose response of oxytocin. The company believes that if Mg2+ reduces the high dose inhibition of oxytocin alone, then the new formulation may improve consistency in clinical trials.
• Enrollment has been completed in the proof-of-concept Phase 2 PREVENTION study of TNX-1900 for the prevention of migraine headache in chronic migraineurs with a total of 88 patients enrolled. PREVENTION is a registration-quality, double-blind, placebo-controlled study.
• Topline results from the PREVENTION Phase 3 trial are expected in the fourth quarter of 2023.

• In July 2023, Tonix announced that the first participant was enrolled in the investigator-initiated Phase 2 STROBE Study of TNX-1900 for the treatment of binge-eating disorder at the Massachusetts General Hospital (MGH) under the direction of Principal Investigator Elizabeth Lawson. Tonix is supporting the STROBE study through a clinical trial agreement with MGH.
• In July 2023, Tonix announced that the first participant was enrolled in a Phase 2 investigator-initiated, proof-of-concept study of TNX-1900 for enhancing social safety learning in social anxiety disorder (SAD) under the direction of Principal Investigator Angela Fang. Tonix entered into an agreement with the University of Washington to examine the potential role of TNX-1900 in enhancing vicarious extinction learning in SAD, compared to healthy controls.
• In July 2023, Tonix announced that the first participant was enrolled in the Phase 2 POWER study of TNX-1900 for the treatment of pediatric obesity with MGH under the direction of Principal Investigator Elizabeth Lawson. MGH is the sponsor of the National Institutes of Health-funded trial, being conducted under an investigator-initiated IND.
• In May 2023, Tonix entered into a research collaboration agreement with the principal investigator of the study, Dr. Antoinette Maassen van den Brink, Professor of Neurovascular Pharmacology, Erasmus University Medical Center, to evaluate the effect of TNX-1900 on capsaicin- or electrical stimulation-induced forehead dermal blood flow in health female volunteers.

TNX-601 ER (tianeptine hemioxalate extended-release tablets): a once-daily orally administered small molecule for the treatment of major depressive disorder (MDD), posttraumatic stress disorder (PTSD), neurocognitive dysfunction associated with corticosteroid use, and potentially Alzheimer’s disease

• Enrollment has been completed in the proof-of-concept Phase 2 UPLIFT study for the treatment of MDD, with 116 patients enrolled. UPLIFT is a registration-quality, double-blind, placebo-controlled study.
• Topline results for the UPLIFT Phase 2 trial are expected in the fourth quarter of 2023.
• Scientists at Tonix’s Research and Development Center (RDC) in Frederick, Md. established the molecular mechanism of action of tianeptine, the active ingredient of TNX-601 ER. The research supports a direct role for restoring neuroplasticity and neurogenesis, and upsets previously held beliefs about the significance of neurotransmitters in treating depression. It also provides clarity on why tianeptine does not cause sexual dysfunction, weight gain or several other treatment-limiting toxicities associated with traditional antidepressants.

TNX-4300 (estianeptine): small molecule oral therapeutic for MDD, bipolar disorder, Alzheimer’s disease and Parkinson’s disease

• In July 2023, the Company announced that it would focus resources on the development of single isomer TNX-4300 as a first-in-class oral therapy for mood disorders, Alzheimer’s disease and other psychiatric and neurodegenerative conditions with memory deficits. The decision follows the Company’s announcement in May 2023 of the isolation and characterization of the (S)-isomer of tianeptine, which activates PPAR-β/δ, restores neuroplasticity in neuronal tissue culture and is free of µ-opioid receptor activity.

TNX-1300 (recombinant double mutant cocaine esterase): biologic for life-threatening cocaine intoxication

• Tonix expects to initiate a potentially pivotal Phase 2 clinical study of TNX-1300 for the treatment of cocaine intoxication in the third quarter of 2023. In 2022, Tonix was awarded a Cooperative Agreement grant from the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health (NIH), to support development of TNX-1300.
• TNX-1300 has been granted Breakthrough Therapy designation by the FDA.

Rare Disease Pipeline

TNX-2900 (intranasal potentiated oxytocin): small peptide for the treatment of Prader-Willi syndrome (PWS)

• TNX-2900 has been granted Orphan Drug designation from the FDA for the treatment of PWS and the preparation of the IND is in process.
•  TNX-2900 is in development to treat PWS and the planned clinical study will study its effects on hyperphagia, or pathological over-eating, in children and young adult patients with PWS.

Immunology Pipeline

TNX-1500 (anti-CD40L monoclonal antibody): third generation anti-CD40L monoclonal antibody for prophylaxis of organ transplant rejection and treatment of autoimmune disorders.

• In May 2023, the IND for prevention of organ rejection in patients receiving a kidney transplant was cleared by FDA. A first-in-human Phase 1 study is expected to start in the third quarter of 2023. The first indication for TNX-1500 will be prophylaxis of organ rejection in adult patients receiving a kidney transplant, but multiple additional indications are possible, including autoimmune diseases. Two peer reviewed publications described the work at the Massachusetts General Hospital on allogeneic transplants in animals.^1,2
