Positive results from confirmatory Phase 3 RESILIENT study reported in December 2023 position Tonmya™ for fibromyalgia for NDA submission second half of 2024; pre-NDA meeting with FDA scheduled for second quarter 2024 Commercial planning underway, including go-to-market, supply chain and manufacturing strategies, for U.S. launch of Tonmya, a potential new first-line, centrally-acting, non-opioid analgesic for the management of fibromyalgia CHATHAM, N.J., April 01, 2024 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals, Inc. (Nasdaq: TNXP) (Tonix or the Company), a fully-integrated biopharmaceutical company with marketed products and a pipeline of development candidates, today announced financial results for the fourth quarter and full year ended December 31, 2023, and provided an overview of recent operational highlights. “Our near-term focus is seeking U.S. marketing approval for Tonmya (cyclobenzaprine HCl sublingual tablets) for the treatment of fibromyalgia from the U.S. Food and Drug Administration (FDA),” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “Our pre-NDA meeting with the FDA is scheduled to take place this quarter and we plan to submit our New Drug Application (NDA) for Tonmya™ in the second half of 2024. We believe the positive Phase 3 RESILIENT results reported in December of 2023 together with the positive results from the first Phase 3 RELIEF study should satisfy the requirements for approval and, if so, would provide the opportunity for Tonix to launch the first FDA-approved drug for fibromyalgia in more than a decade. We believe the activity of Tonmya on improving pain, sleep quality, fatigue and brain fog in the RESILIENT study are indicative of the broad-spectrum of activity in fibromyalgia.” Dr. Lederman added, “While Tonix is focusing its resources on progressing Tonmya toward NDA submission and potential FDA approval, we are seeking partnerships and collaborations on our pipeline programs from government agencies, non-profit organizations and other biotechnology or pharmaceuticals companies. Tonix has already shifted portions of our research and development (R&D) expenses to U.S. government agencies and other institutions through partnerships involving grants and in-kind contributions. These outside collaborations leverage our internal resources, and we believe they provide a capital efficient strategy for progress.” Selected Product Candidates* — Recent Highlights Central Nervous System (CNS) Pipeline Tonmya (also known as TNX-102 SL; cyclobenzaprine HCl sublingual tablets): a centrally-acting, non-opioid, small molecule analgesic taken once-daily at bedtime for the management of fibromyalgia (FM). The Company announced in December 2023 that the Phase 3 RESILIENT study, a registration-quality, double-blind, placebo-controlled study evaluating TNX-102 SL met its pre-specified primary endpoint in the second of two positive Phase 3 clinical trials, significantly reducing daily pain compared to placebo (p=0.00005) in participants with fibromyalgia. Statistically significant and clinically meaningful results were also seen in all key secondary endpoints related to improving sleep quality, reducing fatigue, and improving patient global ratings and overall fibromyalgia symptoms and function. Additionally, as it relates to improving daily pain, treatment with TNX-102 SL showed a robust and clinically meaningful analgesic Cohen’s d effect size of 0.38, with rapid onset of action, separating from placebo for every week of the study. TNX-102 SL was well tolerated with an adverse event pro to prior studies and no new safety signals observed. Tonix plans to submit an NDA to the FDA in the second half of 2024 for TNX-102 SL for the management of fibromyalgia. In January 2024, Tonix presented additional safety and tolerability data from the Phase 3 RESILIENT study that showed TNX-102 SL treatment was not associated with increases in systolic or diastolic blood pressure or body weight, nor were there any reported sexual side effects. In January 2024, Tonix announced that the FDA has conditionally accepted the trade name, Tonmya, for the Company’s drug product candidate TNX-102 SL for the management of fibromyalgia. In February 2024, Tonix announced positive results from its clinical pharmacokinetic (PK) bridging study of Tonmya in healthy adult male and female ethnic Japanese and Chinese volunteers. Results indicate that key PK parameters of cyclobenzaprine are comparable in ethnic Japanese and Chinese volunteers to Caucasian volunteers from a prior PK study. Tonmya was generally well tolerated in the ethnic Japanese and Chinese healthy volunteers. The company expects these data to fulfill the requirement for a bridging study, and enables Tonix to rely on Phase 3 studies RESILIENT and RELIEF results to support regulatory filings for clinical studies in Japan and China where cyclobenzaprine is a new chemical entity (NCE). Tonix holds issued patents for market exclusivity rights of Tonmya in Japan, China, Hong Kong and Taiwan. In February 2024, Tonix selected Rho, Inc., a global contract research organization, to support Tonix’s preparation and planned submission of its NDA to the FDA for the approval of Tonmya for the management of fibromyalgia. In March 2024, Tonix announced the selection of two CMOs, including Almac Pharma Services, as dual supply sources for the potential launch and commercialization of Tonmya in the U.S. In March 2024, Tonix selected EVERSANA, a leading provider of commercialization services to the global life sciences industry, to support the launch strategy and commercial planning of Tonmya in the U.S. Tonix presented additional efficacy data from RESILIENT at the 6th International Congress on Controversies in Fibromyalgia in Brussels, Belgium, March 7-8, 2024. The data showed that Tonmya treatment resulted in an improvement in cognitive dysfunction, or ‘brain fog’, measured by the change in the Fibromyalgia Impact Questionnaire-Revised (FIQ-R) memory item. The FIQ-R cognitive item showed nominal improvement in Tonmya-treated patients vs placebo-treated patients with p-value=0.001 and effect size of 0.31. TNX-102 SL for the treatment of acute stress reaction (ASR) and acute stress disorder (ASD), and prophylaxis against development of posttraumatic stress disorder (PTSD) In February 2024, the Company announced the FDA cleared the Investigational New Drug (IND) application for the Phase 2 investigator-initiated OASIS trial to evaluate TNX-102 SL in reducing the severity of ASR and the frequency of ASD and PTSD. The trial is sponsored by The UNC Institute for Trauma Recovery and supported by a $3 million grant from the U.S. Department of Defense (DoD), which was awarded in September 2023. The proposed Phase 2, Optimizing Acute Stress Reaction Interventions with TNX-102 SL (OASIS) study will examine the safety and efficacy of TNX-102 SL to reduce adverse posttraumatic neuropsychiatric sequelae among patients presenting to the emergency department (ED) after a motor vehicle collision (MVC). The study will enroll approximately 180 trauma survivors at ED study sites in the U.S. Participants will be randomized in the ED to receive a two-week course of either TNX-102 SL 5.6 mg or placebo. Tonix expects the Phase 2 OASIS trial will initiate in the second quarter of 2024. TNX-102 SL for the treatment of Fibromyalgia-Type Long COVID, also known as Post-Acute Sequelae of COVID-19 (PASC) In January 2024, the Company announced the online publication of a research paper in the Journal Pain. The article titled, “Chronic Overlapping Pain Conditions Increase the Risk of Long COVID Features, Regardless of Acute COVID Status,” by Bergmans, et al. 1, found that patients with pre-existing chronic overlapping pain conditions (COPCs) had an increased risk of being diagnosed with symptoms of Long COVID1. Faculty at the University of Michigan directed the research. Commentary on the article titled, “A step towards better understanding chronic overlapping pain conditions” by Fitzcharles, et al,2 is in the same issue of the journal. COPCs include fibromyalgia, chronic fatigue syndrome, migraine headache, irritable bowel syndrome, endometriosis and low back pain. These results contribute to a growing body of evidence that common symptoms of Long COVID in many patients are at least partly driven by central nervous system mechanisms. In September 2023, the Company reported topline results from its Phase 2 PREVAIL proof-of-concept study of TNX-102 SL for fibromyalgia-type Long COVID. TNX-102 SL showed a robust Cohen’s d effect size of 0.50 in improving fatigue relative to placebo; and it showed consistent activity across secondary measures of sleep quality, cognitive function, disability and Patient Global Impression of Change, but did not meet the primary endpoint of multi-site pain reduction at Week 14. TNX-102 SL was generally well tolerated and no new safety signals were observed. The Company intends to request an End-of-Phase 2 meeting with the FDA to discuss a potential Phase 3 program based on a proposed primary outcome measure using the PROMIS Fatigue scale. TNX-1300 (recombinant double mutant cocaine esterase): biologic for life-threatening cocaine intoxication Tonix expects to initiate a Phase 2 clinical study of TNX-1300 for the treatment of cocaine intoxication in emergency rooms in the second quarter of 2024. In 2022, Tonix was awarded a Cooperative Agreement grant from the National Institutes of Health (NIH)’s National Institute of Drug Abuse (NIDA) to support development of TNX-1300. TNX-1300 has been granted Breakthrough Therapy designation by the FDA. TNX-1900 (intranasal potentiated oxytocin): small peptide in development through investigator-initiated studies for bone health in autism, social anxiety disorder (SAD), adolescent obesity and binge eating disorder In November 2023, Tonix announced that the first participant was enrolled in an investigator-initiated Phase 2 study of TNX-1900 for improving bone health in children with autism spectrum disorder, named the BOX study, at Massachusetts General Hospital (MGH). The aim of this DoD funded study is to investigate the efficacy and safety of TNX-1900 as a novel therapeutic agent to increase bone density and improve bone structure and strength in children with autism spectrum disorder. Tonix is providing active drug and placebo for the BOX study as part of a drug donation agreement with MGH. MGH is the sponsor of the trial, which is being conducted under an investigator-initiated IND application. TNX-1900 is also being studied in three other ongoing investigator-initiated Phase 2 studies as follows: MGH Phase 2 study for binge-eating disorder (BED) University of Washington Phase 2 study for social anxiety disorder (SAD) MGH Phase 2 study for adolescent obesity Rare Disease Pipeline TNX-2900 (intranasal potentiated oxytocin): small peptide for the treatment of Prader-Willi syndrome (PWS) In December 2023, Tonix announced that the FDA has cleared the IND application to support clinical development of TNX-2900 to treat PWS in children and adolescents. The Phase 2 study approved under the IND is a dose-finding study involving approximately 36 PWS patients divided into four groups with approximately nine per group. One group will receive placebo and three groups will receive different dosage regimens of TNX-2900. TNX-2900 for the treatment of PWS was granted Orphan Drug designation by the FDA in 2022. In March 2024, Tonix announced that it received Rare Pediatric Disease designation from the FDA for TNX-2900 for the treatment of PWS. Immunology Pipeline TNX-1500 (anti-CD40L Fc-modified humanized monoclonal antibody): third generation anti-CD40L monoclonal antibody for prophylaxis of organ transplant rejection and treatment of autoimmune disorders. The first indication for TNX-1500 is 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 (MGH) on allogeneic transplants in animals were published.3,4 Preclinical studies have shown that TNX-1500 maintains the activity of first-generation monoclonal antibodies (mAbs), yet with reduced risk of thrombotic complications.3-5 Modeling studies from animal pharmacokinetic data3 predict a half-life of approximately three weeks for TNX-1500 in humans, which supports a monthly i.v. dosing regimen. This analysis together with TNX-1500’s activity and tolerability in animals, suggests that the protein engineering of TNX-1500’s Fc region has achieved its design goals. In October 2023, the Company announced data from two oral presentations delivered at medical meetings in 2023. The oral presentations titled, “Pilot Evaluation of a Clinical Xeno Heart Transplant Regimen in a Preclinical Model” and “Extended Survival of 9- and 10-Gene Edited Pig Heart Xenografts with Ischemia Minimization and CD154 Costimulation Blockade-Based Immunosuppression” by Dr. Ikechukwu Ileka et al. include data demonstrating the use of TNX-1500 as maintenance therapy after xenogeneic heart transplant in non-human primates. In both studies, genetically engineered (GE) pigs in baboon transplants were treated with cold-perfused ischemia minimization and a novel costimulation-based immunosuppressive regimen that includes TNX-1500. In October 2023, Tonix announced that a study published in the Journal Nature5 by faculty at the Center for Transplantation Sciences, MGH, in collaboration with biotechnology company, eGenesis, utilized TNX-1500 as part of the immune modulating regimen to prevent organ transplant rejection. The Nature article titled, “Design and testing of a humanized porcine donor for xenotransplantation” includes data that provide additional support for TNX-1500’s activity in preventing pig xenograft organ rejection and for its safety and tolerability in non-human primates. In February 2024, Tonix announced the completion of the clinical stage of its Phase 1 single ascending dose study of TNX-1500 in healthy volunteers. The primary objectives of the study are to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of intravenous TNX-1500. Topline results are expected in the third quarter of 2024. This first-in-human study is intended to support dosing in a planned Phase 2 trial in kidney transplant recipients. In March of 2024, the MGH announced the first transplant of a genetically modified pig kidney into a living patent in collaboration with eGenesis, which produced the pig donors.6 Some of the pre-clinical work that supported this transplant was performed in collaboration with Tonix and used TNX-1500.5 Infectious Disease Pipeline TNX-1800 (modified recombinant horsepox virus, live vaccine): potential vaccine to protect against COVID-19 designed to express the SARS-CoV-2 spike protein Results from a study with our TNX-1800 vaccine that showed animals were protected from challenge with SARS-CoV-2 were published as an article in the peer reviewed journal, Viruses in 2023.7 In November 2023, Tonix announced that NIH and National Institute of Allergy and Infectious Diseases (NIAID) will conduct a Phase 1 clinical trial with TNX-1800 as part of Project NextGen. NIAID will cover the full cost of the clinical trial, including operations and related analyses. Tonix will be responsible for providing clinical trial materials, and upon completion will have the right to rely on the findings in regulatory filings with the FDA to support the approval of its COVID-19 vaccine and other vaccines based on the recombinant pox vaccine (RPV) platform. We believe the TNX-1800 vaccine development plan addresses several priority vaccine attributes advanced by the White House Office of Science and Technology Policy’s Pandemic Preparedness Plan,8 the National Biodefense Science Board9 and BARDA.10 Tonix believes its RPV platform can address a wide variety of disease targets of public health interest. TNX-801 (recombinant horsepox virus, live vaccine): potential vaccine to protect against mpox disease and smallpox. Results from a study with our TNX-801 vaccine that showed animals were protected from mpox were reported at a meeting in the first quarter of 2020 and published as an article in the peer reviewed journal, Viruses in 2023.11 On December 14, 2023, Dr. Lederman participated in a panel discussion on Vaccine Research & Development at the National Academies of Sciences, Engineering, and Medicine (NAS) Committee on the Current State of Research, Development, and Stockpiling of Smallpox Medical Countermeasures public meeting. Discussions explored lessons learned from the recent COVID-19 pandemic and mpox multi-country outbreak to inform an evaluation of the current state of research, development, and stockpiling of smallpox readiness and response measures. The Consensus Study Report was issued on March 28, 2024.12 Some of the conclusions included recommendations for single dose vaccines, safer vaccines, vaccine platforms and attention to supply chain and manufacturing. Tonix believes TNX-801 has the potential to address some of the recommendations from the NAS Committee since it provides single dose protection to animals, and has the potential for favorable dose, manufacturing and cold chain requirements. In August 2023, Tonix received the official written response from a Type B pre-IND meeting with the FDA to develop TNX-801 as a potential vaccine to protect against mpox disease (formerly known as monkeypox) and smallpox. Tonix believes the FDA feedback provides a path to agreement on the design of a Phase 1/2 study and the overall clinical development plan. The Phase 1/2 clinical trial will assess the safety, tolerability, and immunogenicity of TNX-801, following the submission and clearance of an IND. Concerns about current state of new smallpox and mpox vaccines in development have been raised by the U.S. Bipartisan Commission on Biodefense13 and by an outbreak of mpox in the Democratic Republic of the Congo.14 Results from a study with our TNX-801 vaccine that showed decreased virulence relative to traditional live vaccinia vaccine strains were posted on the website BioRxiv in 2023.15 Broad-spectrum anti-viral programs Tonix is developing potential broad-spectrum antiviral drugs in three programs: CD45-targeted therapeutics (TNX-4200), cathepsin inhibitors (TNX-3900) and viral glycan-targeted engineered biologics (TNX-4000). In 2020, the DoD announced that they are seeking broad spectrum antiviral drugs since it would be hard to predict which or how many viruses may be deployed on the battlefield.16 Tonix hopes that one or more of our programs may help the DoD address that goal.

报告缩略图节选2024年1月，FDA共批准2款药品，均为化药（1款是新分子实体）；2月，FDA批准了7款药品，包含6款化药（1款是新分子实体）和1款生物制品。全球药品研发情况如下图所示，具体的药品名单可扫描文末二维码加医药地理小助手微信获取完整报告。2. 2024年1-2月全球重磅获批药物分析2.1 首款获FDA批准治疗传染性软疣的家用药物Zelsuvmi (Berdazimer）Berdazimer是FDA在1月批准的新分子实体。2024年01月05日，美国FDA批准了Ligand Pharmaceuticals Incorporated的柏达姆钠 Berdazimer  sodium（SB206），商品名：Zelsuvmi®，剂型：局部凝胶，用于成人和1岁及以上儿科患者传染性疣（MC）的局部治疗。传染性软疣，俗称“水瘊子”，是由传染性软疣病毒(MCV)引起的一种高度传染性的皮肤感染。其特征是皮肤颜色至红色病变，中央有脐状病毒核心。主要通过接触传播，包括皮肤与皮肤的直接接触（包含性传播）。感染者大部分是儿童和免疫功能低下的成年人，每年大约有600万美国人（主要是儿童）被感染。然而，高达73%的儿童未得到治疗。Berdazimer是由Ligand Pharmaceuticals于2023年9月从Novan收购的外用一氧化氮释放剂（凝胶），尽管其治疗传染性软疣的作用机制尚不清楚，但NO已知具有广谱抗菌和抗病毒活性。该药物是第一个也是唯一一个可以由患者、父母或护理人员在家中、医生办公室外或其他医疗场所使用的局部处方药，用于治疗这种高度传染性的病毒性皮肤感染。Berdazimer并不是FDA批准首个治疗传染性软疣的药物，在2023年7月24日FDA批准了Ycanth（斑蝥素）用于治疗2岁以上的传染性软疣患者。Ycanth(cantharidin，斑蝥素)是一种独特的药物-器械组合，一种起泡剂，包含斑蝥素(0.7%w/v)配方，通过一次性涂药器输送，用于精确的局部给药和靶向给药。Ycanth是美国FDA批准的第一种治疗传染性软疣的药物。值得注意的是：与很多皮肤病外用药不同，Ycanth仅限在医院中用。这是由于其活性成分斑蝥素的毒性大，不慎进入口中，可能导致严重伤害，甚至致命。而且，即使干燥后，斑蝥素也高度易燃。相比之下，Berdazimer最大的优势是可以在家中使用。2.2 全球首款补体因子D抑制剂Voydeya（Danicopan）在日本获批上市 用于治疗阵发性睡眠性血红蛋白尿症2024年1月18日，日本厚生劳动省批准阿斯利康（AstraZeneca）的“first-in-class”口服小分子Voydeya（danicopan）作为标准疗法补体因子C5抑制剂Ultomiris（ravulizumab）或Soliris（eculizumab）的附加疗法，用于接受C5抑制剂治疗时发生显着血管外溶血（EVH）的阵发性睡眠性血红蛋白尿症（PNH）患者亚群。这是Danicopan在全球范围内的首次获批。PNH是获得性造血干细胞基因突变引起血细胞膜缺陷所致的慢性血管内溶血，常在睡眠时加重，可伴发作性血红蛋白尿、潜在的骨髓衰竭和血栓形成，已被纳入我国第一批罕见病目录。亚洲发病率高于欧美。而就在去年年底，2023年12月5日，FDA刚刚批准了诺华的补体因子B抑制剂伊普可泮Fabhalta（iptacopan）上市，用于成人阵发性睡眠性血红蛋白尿症（PNH）患者的治疗，是首个获FDA批准的口服单药治疗成人PNH的药物。相比C5抑制剂疗法，Danicopan和Iptacopan可选择性地抑制替代通路中的关键补体因子D/B，阻断C3转化酶生产而抑制替代通路活性，阻止C3b片段在患者血红细胞上的沉积，控制PNH患者红细胞分解与血管外溶血，解决PNH患者在接受C5抑制剂治疗时出现临床显著的血管外溶血（EVH）的需求。2.3 FDA批准新型抗生素组合Exblifep（Cefepime /Enmetazobactam）用于治疗复杂尿路感染该药物是FDA在2月批准的新分子实体。Exblifep是由Allecra Therapeutics研发的头孢吡肟（Cefepime，一种头孢菌素类抗菌药物）和恩美他唑巴坦（Enmetazobactam，一种β-内酰胺酶抑制剂）的联合用药，于2024年2月22日FDA批准上市。适用于18岁及以上由指定敏感微生物（大肠杆菌、肺炎克雷伯菌、铜绿假单胞菌、奇异变形杆菌和阴沟肠杆菌复合物）引起的复杂尿路感染（cUTI）患者，包括肾盂肾炎。复杂尿路感染cUTI通常是由革兰氏阴性菌引起，约占美国所有医疗保健相关感染的19%。这种组合旨在对抗革兰氏阴性菌的抗菌耐药性，特别是由广谱β内酰胺酶（ESBL）和头孢菌素酶（AmpC）介导的耐药性有显著作用。在2023年FDA也曾批准过一款抗生素组合疗法。2023年5月23日，FDA曾批准的Xacduro（β-内酰胺类抗生素舒巴坦+β-内酰胺酶抑制剂杜洛巴坦），用于治疗18岁及以上患有鲍曼不动杆菌（或称鲍曼-醋酸钙不动杆菌复合群）敏感菌株引起的医院获得性细菌性肺炎（HABP）和呼吸机相关性细菌性肺炎，是首个用于治疗鲍曼不动杆菌细菌性肺炎的组合抗菌疗法。3. 2024年1-2月主要临床试验与结果复宏汉霖靶向PD-1斯鲁利单抗联合化疗一线治疗晚期鳞状非小细胞肺癌的3期临床试验结果公布ASTRUM-004数据发表在肿瘤学国际权威期刊Cancer Cell上（IF：50.3）。这是一项随机、双盲、国际多中心3期研究，旨在研究斯鲁利单抗对比安慰剂分别联合化疗在既往未接受治疗的晚期鳞状非小细胞肺癌患者中的疗效和安全性。无进展生存期（PFS）的更新分析显示，中位随访时长为16.9个月时，斯鲁利单抗-化疗组相对于安慰剂-化疗组在中位PFS上持续获益。在预设的各亚组分析中，斯鲁利单抗-化疗组在PFS的HR值上均展现出优势。总生存期（OS）的最终分析显示，中位随访时长为31.1个月时，治疗方案中添加斯鲁利单抗显著延长了中位OS（22.7 vs. 18.2个月；HR 0.73）。4. 2024年1-2月中国新药分析4.1 2024年1月NMPA批准的新药加格列净四环医药糖尿病1类新药加格列净获批上市。这是国内第二个获批上市的自主研发的SGLT2抑制剂创新药，首个是来自恒瑞医药的恒格列净。加格列净是一种钠-葡萄糖协同转运蛋白2（SGLT2）抑制剂，通过抑制SGLT2，减少滤过葡萄糖的重吸收，降低葡萄糖的肾阈值，从而增加尿糖排泄。仑卡奈单抗迄今为止第一款在我国获批上市的抗Aβ抗体药物仑卡奈单抗，用于轻度阿尔茨海默症（AD）和阿尔茨海默症（AD）引起的轻度认知障碍（MCI）疾病的改善治疗。仑卡奈单抗由卫材和渤健联合开发，2023年1月，获得FDA加速批准上市，7月6日，FDA宣布在确认临床疗效后，将仑卡奈单抗转为传统批准，成为自2003年以来第一个获得美国FDA完全批准的阿尔茨海默病新药。此后，该药9月在日本获得批准，中国是第三个批准仑卡奈单抗上市的国家。此次这一药物在中国的成功上市，标志着阿尔茨海默病治疗领域迎来了一个新的里程碑。司美格鲁肽片（Rybelsus）GLP-1受体激动剂司美格鲁肽是近年来最火爆的药。其共有三款产品在售，分别为Ozempic（注射用降糖药）、Rybelsus（口服降糖药片剂）、Wegovy（注射用减重药）。片剂的获批大大提升了患者的依从性！但目前用于减重的司美格鲁肽注射液Wegovy还没在国内获批。两款进口偏头痛药物加卡奈珠单抗&瑞美吉泮口崩片1月份，来自礼来的一款抗体和来自辉瑞的一款小分子在国内获批预防/治疗偏头痛，分别靶向降钙素基因相关肽CGRP及其受体CGRP-R。在我国，礼来的加卡奈珠单抗注射液（Galcanezumab）获批用于成人偏头痛的预防性治疗，而辉瑞的瑞美吉泮口崩片（Rimegepant）获批用于成年人有或无先兆偏头痛的急性治疗。实际上在此之前，FDA批准加卡奈珠单抗用于偏头痛预防和丛集性头痛治疗，批准瑞美吉泮用于偏头痛预防和急性偏头痛治疗，且瑞美吉泮还是全球8款已上市CGRP靶向药中唯一一款可同时用于急性治疗和预防偏头痛的药物。4.2 2024年2月NMPA批准的新药泽沃基奥仑赛注射液2024年2月23日，NMPA批准科济药业的泽沃基奥仑赛注射液（赛恺泽）上市，用于治疗复发或难治性多发性骨髓瘤成人患者，既往经过至少3线治疗后进展（至少使用过一种蛋白酶体抑制剂及免疫调节剂）。泽沃基奥仑赛是国内上市的第五款CAR-T细胞产品，同时也是第二款靶向BCMA的CAR-T产品。珂罗利单抗注射液2024年2月7日，罗氏的C5抑制剂珂罗利单抗注射液（crovalimab，商品名：派圣凯）获NMPA批准上市，用于未接受过补体抑制剂治疗的阵发性睡眠性血红蛋白尿症（PNH）成人和青少年（≥12岁）患者。这是该产品在全球所有国家中的首次获批，也是罗氏第一次在中国市场实现一款创新药物的全球首发。对比已上市的依库珠单抗注射液和瑞利珠单抗注射液（均为静脉注射），珂罗利单抗注射液最大的优势是皮下注射，可由患者每月在家自行皮下注射给药1次实现治疗，大大提升了依从性。以上为本次医药地理全球/中国新药研发月报的部分内容展示，想要获得本次直播的完整PPT内容请扫描下方二维码联系医药地理小助手官方微信哦。每场直播都可以扫描二维码查看精彩回放。END如需获取更多数据洞察信息或公众号内容合作，请联系医药地理小助手微信号：pharmadl001

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].
