Gap in non-oral prescriptions relative to AHS guidelines represents an opportunity to increase awareness of Tonix’s two FDA-approved non-oral treatments for acute migraine Zembrace® SymTouch® (sumatriptan injection) and Tosymra® (sumatriptan nasal spray) are indicated for the treatment of acute migraine in adults CHATHAM, N.J., June 18, 2024 (GLOBE NEWSWIRE) -- Tonix Pharmaceuticals Holding Corp. (Nasdaq: TNXP) (Tonix or the Company), a fully-integrated biopharmaceutical company with marketed products and a pipeline of development candidates, presented data from a poster presentation at the 66th Annual Scientific Meeting of the American Headache Society (AHS), held June 13-16, 2024. A copy of the Company’s poster presentation is available under the Scientific Presentations tab of the Tonix website at www.tonixpharma.com. In the poster presentation titled, “American Headache Society Consensus Statement and Other Recommendations: How Many Practitioners Comply With the Recommendations?,” a retrospective review of real-world data compares real world usage of non-oral migraine products with the most recent AHS consensus statement. The data reaffirms several past recommendations from the AHS and stresses the need for customizing treatment of migraine headaches to the needs of patients, as well as using the most appropriate route of administration for any given acute attack based on the clinical presentation. So far, real world data show that compliance with the guidelines and the consensus statement have yet to be achieved but has the potential to be increased. Specifically, the data show the use of non-oral drugs for treating an acute migraine attack was only 7% in 2012 and has decreased to below 4% in 2023, when the potential need for such drugs is anticipated to be a significant percentage of patients based on epidemiological data. “We believe personalizing therapy for migraine is the future and it is hoped that non-oral medicines will address some of the persistent dissatisfaction patients experience with their migraine treatments,” said Seth Lederman, M.D., Chief Executive Officer of Tonix Pharmaceuticals. “We hope that educating prescribers about the importance of customized treatments will lead to enhanced satisfaction and improve the quality of life of migraine patients. This represents an opportunity for growth in non-oral first-line therapeutics such Tonix’s Zembrace SymTouch and Tosymra.” “Inconsistent and incomplete response to traditional or emerging oral acute migraine medications continue to be a burden for individuals living with migraines. We believe that both Zembrace SymTouch and Tosymra, due to their rapid-onset and route of administration are well suited to address this unmet need,” said James Hunter, Executive Vice President of Commercial Operations at Tonix Pharmaceuticals and President of Tonix Medicines. Zembrace SymTouch is the only actively promoted brand of sumatriptan autoinjector in the U.S. (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)2. Tosymra employs Intravail® permeation enhancer technology and is pharmacokinetically equivalent to 4 mg subcutaneous sumatriptan.3,4, Tosymra delivers migraine pain relief in as little as 10 minutes with just one spray for some patients (13% vs. 5% for placebo).1,4,5 About Migraine Nearly 40 million people in the United States suffer from migraine6 and it has been recognized as the second leading cause of disability in the world7. 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)8. 1Mathew NT, et al.
