Zembrace® SymTouch® and Tosymra® will be marketed by Tonix Medicines, Tonix’s wholly-owned commercial subsidiary Commercial capabilities prepare Tonix for the potential launch in 2025 of Tonmya™ for the management of fibromyalgia, assuming FDA approval CHATHAM, N.J., March 19, 2024 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals, Inc. (Nasdaq: TNXP) (Tonix or the Company), a biopharmaceutical company with marketed products and a pipeline of development candidates, today announced that it will achieve its goal of transitioning to a fully integrated pharmaceutical company on April 1, 2024. Since the acquisition of Zembrace® SymTouch® (sumatriptan injection) 3 mg and Tosymra® (sumatriptan nasal spray) 10 mg on June 30, 2023, Tonix Pharmaceuticals has been putting in place the personnel, systems and contracts required to support a commercial organization. Both products are indicated for the treatment of acute migraine with or without aura in adults. “Tonix will become a fully integrated biopharmaceutical company with a mission of developing and marketing innovative, high-value therapeutics,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Tonix will assume responsibility for the distribution, selling and marketing of Zembrace SymTouch and Tosymra, as well as supply chain, regulatory and quality control of the two products.” Dr. Lederman added, “The assumption of commercial activities by Tonix represents an important milestone in the evolution of Tonix as we continue to build and strengthen our commercial organization for the potential launch of Tonmya™ (cyclobenzaprine HCl sublingual tablets) for fibromyalgia in 2025, assuming approval by the U.S. Food and Drug Administration (FDA).” About Zembrace® SymTouch® and Tosymra® Zembrace SymTouch is the only actively promoted brand of sumatriptan autoinjector in the United States (other sumatriptan autoinjector products on the market are Imitrex® and generics to Imitrex®). It has a unique low dose and has demonstrated onset of migraine pain relief in as few as 10 minutes (17% of patients vs. 5% for placebo).1 Zembrace SymTouch also demonstrated migraine pain freedom for 46% of patients (vs 27% for placebo) at 2 hours in a single-attack, double-blind study (N=230).1 Zembrace SymTouch currently has patent protection to 2036. Tosymra employs Intravail® permeation enhancer technology and is pharmacokinetically equivalent to 4 mg subcutaneous sumatriptan.2 Tosymra delivers migraine pain relief in as little as 10 minutes with just one spray for some patients (13% vs. 5% for placebo).2 Tosymra currently has patent protection to 2031. About Migraine Nearly 40 million people in the United States suffer from migraine3 and it has been recognized as the second leading cause of disability in the world.4 Migraine is characterized by debilitating attacks lasting four to 72 hours with multiple symptoms, including pulsating headaches of moderate to severe pain intensity often associated with nausea or vomiting, and/or sensitivity to sound (phonophobia) and sensitivity to light (photophobia).3 References: Zembrace SymTouch [package insert].

Generalized pustular psoriasis (GPP) is a rare, chronic, heterogenous neutrophilic inflammatory disease associated with skin and systemic symptoms, such as fever, pain, and fatigue1,2,3,4 In China, SPEVIGO®’s expanded approval adds the reduction of occurrences of GPP in pediatric patients aged 12 and above weighing ≥40 kg, and adults5 The US FDA’s approval expands the use of SPEVIGO® to include the treatment of GPP in adults and pediatric patients aged 12 and above weighing ≥40 kg, making it the first targeted therapy that addresses the need for acute and chronic treatment for GPP patients6 SPEVIGO® is currently approved in 48 countries7 Boehringer Ingelheim today announced that the US Food and Drug Administration (FDA) has approved SPEVIGO® (spesolimab-sbzo) injection for the treatment of generalized pustular psoriasis (GPP) in adults and pediatric patients aged 12 and above weighing ≥40 kg.5 This approval follows the Chinese National Medical Products Administration’s (NMPA) recent approval of SPEVIGO® for the reduction of occurrence of generalized pustular psoriasis (GPP) in adolescents from 12 years of age with a body weight ≥40 kg and adults. SPEVIGO® is a novel, humanized selective IgG1 antibody that binds to interleukin-36 receptor (IL-36R), a key part of a signaling pathway within the immune system shown to be involved in the cause of GPP.8,9,10,11,12 The regulatory authorities’ decisions are majorly based on the positive results of the EFFISAYIL® 2 clinical trial, a 48-week clinical trial that showed that SPEVIGO® significantly reduced the risk of GPP flares by 84%, compared with placebo. In the trial with 123 patients, no flares were observed after week 4 of SPEVIGO® subcutaneous treatment in the high-dose group (n=30).13,14,15,16 In the Effisayil® 2 trial, SPEVIGO® was associated with an increased incidence (≥9 cases per 100 patient-years) of injection site reaction, urinary tract infection, arthralgia, and pruritus compared to placebo. “Until now, people living with GPP have not had any approved options to treat their disease,” said Bruce Strober, MD, PhD, Clinical Professor, Dermatology, Yale University and Central Connecticut Dermatology. “SPEVIGO® has the potential to redefine the treatment options for the patients we serve.” Distinct from plaque psoriasis, GPP is a rare, chronic, heterogenous, inflammatory neutrophilic disease associated with painful skin manifestations and systemic symptoms, such as fever, pain, and fatigue.1-4 GPP varies widely between individuals living with the condition, with symptoms presenting on a continuum, which means that it can present in either a persistent or a relapsing course.2-4 GPP often requires emergency care and can lead to life-threatening complications, such as multi-organ failure and sepsis.17 GPP’s unpredictable nature can potentially have significant long-term impacts on quality of life for people living with it, and may cause fear and anxiety over the disease course.3,18 “SPEVIGO®’s new approvals constitute a fundamental change for people living with GPP, addressing their huge need for acute and chronic treatment,” said Carinne Brouillon, Member of the Board of Managing Directors and Head of Human Pharma at Boehringer Ingelheim. “Experiencing GPP can be mentally and physically devastating, leaving those affected with uncertainty and fear of the next episode. Therefore, expanding the treatment of GPP is a critical step towards addressing patients’ needs.” About SPEVIGO® SPEVIGO® is a novel, humanized, selective antibody that specifically blocks the activation of the IL-36R, a signaling pathway within the immune system shown to be involved in the pathogenesis of several autoinflammatory diseases, including GPP.7-11 It is the first targeted therapy for the treatment of GPP and has been evaluated in the largest clinical program specifically for the treatment of patients with GPP.10,19 What is SPEVIGO®? SPEVIGO® is a prescription medicine used to treat generalized pustular psoriasis (GPP) in adults and children 12 years of age and older who weigh at least 88 pounds (40 kg). It is not known if SPEVIGO® is safe and effective in children under 12 years of age or who weigh less than 88 pounds. Important Safety Information Do not receive SPEVIGO® if you or your child have had a severe or life-threatening allergic reaction to spesolimab-sbzo or any of the ingredients in SPEVIGO®. What is the most important information I should know about SPEVIGO®? SPEVIGO® may cause serious side effects, including: Infections. SPEVIGO® may lower the ability of your or your child’s immune system to fight infections and may increase your or your child’s risk of infections. Your healthcare provider should check you or your child for infections and tuberculosis (TB) before starting treatment with SPEVIGO® and may treat you or your child for TB before you begin treatment with SPEVIGO® if you have a history of TB or have active TB. Your healthcare provider should watch you or your child closely for signs and symptoms of TB during or after treatment with SPEVIGO®. Tell your healthcare provider right away if you or your child have an infection or have symptoms of an infection during or after treatment with SPEVIGO®, including: fevers, chills, or sweats muscle aches cough shortness of breath blood in your phlegm (mucus) burning when you urinate urinating more often than normal Allergic reactions and infusion-related reactions. Serious allergic reactions may happen during or after your or your child’s SPEVIGO® injection. If you or your child have a serious allergic reaction, your healthcare provider will stop treatment with SPEVIGO®. If you or your child are given SPEVIGO® in a vein (intravenously) and have an infusion- related reaction, your healthcare provider will stop your or your child’s SPEVIGO® infusion and treat your or your child’s symptoms and may restart SPEVIGO® at a slower infusion rate.

CL-SPG-100004 03.18.2024 About the EFFISAYIL® clinical trial program The EFFISAYIL® clinical trial program evaluated the largest and broadest population of GPP patients in trials of a therapy specifically targeting the IL-36 pathway for GPP:10,18 EFFISAYIL® 1: A Phase II study that demonstrated treatment with a single intravenous dose of spesolimab significantly improved signs and symptoms of GPP in patients experiencing a flare, including rapid pustular and skin clearance. These results supported the approval of spesolimab as the first specific treatment for GPP flares in adults in major markets10,20 EFFISAYIL® 2: A Phase IIb study that showed spesolimab significantly reduced the risk of GPP flares by 84% over 48 weeks compared to placebo. In the trial with 123 patients, no flares were observed after week 4 of spesolimab SC treatment in the high-dose group (n=30)12–15 EFFISAYIL® ON: An open-label extension study to evaluate the long-term safety and efficacy of spesolimab in patients with GPP who have completed previous spesolimab trials21 About generalized pustular psoriasis (GPP) GPP is a chronic, heterogenous, neutrophilic inflammatory disease associated with skin and systemic symptoms that is distinct from plaque psoriasis. GPP is recognized as a separate clinical entity from other forms of psoriasis, with the IL-36 pathway being a key driver of GPP and triggering response to treatment.1 Prevalence of GPP is low and varies considerably across geographical regions, ranging from 1.76 to 124 patients per million persons in reports from key countries, including France, Japan, Sweden, and South Korea.2 GPP can become life-threatening (mortality rates ranging from 2% to 16%) due to severe complications, such as multisystem organ failure and sepsis requiring urgent hospital care; many GPP patients also suffer from various comorbidities, which contribute to the ongoing burden for the patient and healthcare systems.2,16,17 GPP symptoms appear unpredictable and present on a continuum, which greatly impacts a patient’s quality of life, and may cause fear and anxiety over the disease course, as well as long-term impacts on quality of life related to work/school, emotional health, social activities, and finances.2,3,4 About Boehringer Ingelheim Boehringer Ingelheim is working on breakthrough therapies that transform lives today and for generations to come.
