Tonix Pharmaceuticals Presents Real-World Claims Analysis And Launches TONMYA For Fibromyalgia Treatment
Tonix Pharmaceuticals commercially launched TONMYA in November 2025, the first new fibromyalgia drug for adults in the U.S. approved in over 15 years. Data presented at ISPOR 2026 represent a retrospective, multi-year, multi-cohort study using the Symphony Health closed claims database, encompassing administrative medical and pharmacy claims collected between April 2021 and April 2024. The study’s objective was to evaluate real-world characteristics, including demographics, comorbidities, and healthcare resource utilization among adults diagnosed with fibromyalgia (ICD-10-CM diagnosis code M79.7). The Year 3 cohort (April 2023 to March 2024) included 261,776 adult patients, with a median age of 53 years. Most patients were female (92.1%). Patients were White non-Hispanic (49.6%), Hispanic (22.4%), Other (19.6%), and Black (8.3%). Comorbidity burden was high, with 93.2% of patients having at least one fibromyalgia-related comorbidity, most commonly anxiety/depression (63.9%), dorsalgia/back pain (56.5%), hypertensive diseases (51.4%), and joint pain (48.4%). The medication use reflects reliance on multimodal pharmacologic strategies to manage fibromyalgia-related symptoms in routine clinical practice. TONMYA (cyclobenzaprine HCl sublingual tablets) is a patented sublingual tablet formulation of cyclobenzaprine hydrochloride which provides rapid transmucosal absorption and reduced production of a long half-life active metabolite, norcyclobenzaprine, due to bypass of first-pass hepatic metabolism. As a multifunctional agent with potent binding and antagonist activities at the 5-HT2A serotonergic, a1-adrenergic, H1-histaminergic, and M1-muscarinic receptors, TONMYA was approved on August 15, 2025, by the FDA for the treatment of fibromyalgia in adults. TONMYA is the first new prescription medicine approved for fibromyalgia in more than 15 years. TONMYA was investigated as TNX-102 SL. TNX-102 SL is also being developed to treat acute stress disorder/acute stress reaction, and major depressive disorder. The United States Patent and Trademark Office (USPTO) issued United States Patent No. 9636408 in May 2017, Patent No. 9956188 in May 2018, Patent No. 10117936 in November 2018, Patent No. 10,357,465 in July 2019, and Patent No. 10736859 in August 2020. The Protectic protective eutectic and Angstro-Technology formulation claimed in the patent are important elements of Tonix’s proprietary TONMYA composition. These patents are expected to provide TONMYA with U.S. market exclusivity until 2034/2035. TONMYA is indicated for the treatment of fibromyalgia in adults. TONMYA is contraindicated: In patients with hypersensitivity to cyclobenzaprine or any inactive ingredient in TONMYA. Hypersensitivity reactions may manifest as an anaphylactic reaction, urticaria, facial and/or tongue swelling, or pruritus. Discontinue TONMYA if a hypersensitivity reaction is suspected. With concomitant use of monoamine oxidase (MAO) inhibitors or within 14 days after discontinuation of an MAO inhibitor. Hyperpyretic crisis seizures and deaths have occurred in patients who received cyclobenzaprine (or structurally similar tricyclic antidepressants) concomitantly with MAO inhibitors drugs. During the acute recovery phase of myocardial infarction, and in patients with arrhythmias, heart block or conduction disturbances, or congestive heart failure. In patients with hyperthyroidism. Embryofetal toxicity: Based on animal data, TONMYA may cause neural tube defects when used two weeks prior to conception and during the first trimester of pregnancy. Advise females of reproductive potential of the potential risk and to use effective contraception during treatment and for two weeks after the final dose. Perform a pregnancy test prior to initiation of treatment with TONMYA to exclude use of TONMYA during the first trimester of pregnancy. Serotonin syndrome: Concomitant use of TONMYA with selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants, tramadol, bupropion, meperidine, verapamil, or MAO inhibitors increases the risk of serotonin syndrome, a potentially life-threatening condition. Serotonin syndrome symptoms may include mental status changes, autonomic instability, neuromuscular abnormalities, and/or gastrointestinal symptoms. Treatment with TONMYA and any concomitant serotonergic agent should be discontinued immediately if serotonin syndrome symptoms occur and supportive symptomatic treatment should be initiated. If concomitant treatment with TONMYA and other serotonergic drugs is clinically warranted, careful observation is advised, particularly during treatment initiation or dosage increases. Tricyclic antidepressant-like adverse reactions: Cyclobenzaprine is structurally related to TCAs. TCAs have been reported to produce arrhythmias, sinus tachycardia, prolongation of the conduction time leading to myocardial infarction and stroke. If clinically significant central nervous system symptoms develop, consider discontinuation of TONMYA. Caution should be used when TCAs are given to patients with a history of seizure disorder, because TCAs may lower the seizure threshold. Patients with a history of seizures should be monitored during TCA use to identify recurrence of seizures or an increase in the frequency of seizures. Atropine-like effects: Use with caution in patients with a history of urinary retention, angle-closure glaucoma, increased intraocular pressure, and in patients taking anticholinergic drugs. TONMYA monotherapy may cause central nervous system depression. Concomitant use of TONMYA with alcohol, barbiturates, or other central nervous system depressants may increase the risk of central nervous system depression. Advise patients not to operate a motor vehicle or dangerous machinery until they are reasonably certain that TONMYA therapy will not adversely affect their ability to engage in such activities. In clinical studies with TONMYA, oral mucosal adverse reactions occurred more frequently in patients treated with TONMYA compared to placebo. Advise patients to moisten the mouth with sips of water before administration of TONMYA to reduce the risk of oral sensory changes (hypoesthesia). Consider discontinuation of TONMYA if severe reactions occur. The most common adverse reactions (incidence =2% and at a higher incidence in TONMYA-treated patients compared to placebo-treated patients) were oral hypoesthesia, oral discomfort, abnormal product taste, somnolence, oral paresthesia, oral pain, fatigue, dry mouth, and aphthous ulcer. MAO inhibitors: Life-threatening interactions may occur. Other serotonergic drugs: Serotonin syndrome has been reported. Central nervous system depressants: Central nervous system depressant effects of alcohol, barbiturates, and other central nervous system depressants may be enhanced. Tramadol: Seizure risk may be enhanced.
