A diagnosis of fibromyalgia does not exclude the presence of other clinically important illnesses.” 1 • Tender Points are not required to diagnose fibromyalgia • The 2016 ACR criteria specifically eliminated the 1990 requirement 2 for tender points • Changes in mean pain cannot be compared between different studies • Mean pain changes vary between trials even for the same drug, same inclusion criteria and same statistical methods • TONMYA’s registrational studies evaluated a different population of fibromyalgia patients (ACR 2016 criteria) than the prior approved products’ studies (ACR 1990 criteria) • TONMYA also employed more rigorous analytic methods to account for “missing data” (earlier trials used single imputation methods; TONMYA Trials used multiple imputation) • Expert Consensus holds that “Clinically Meaningful” is a ≥ 30% reduction in pain from baseline 3,4 Opportunities to Educate the Community about Fibromyalgia 1 Wolfe F, et al.

© 2025 Tonix Pharmaceuticals Holding Corp. 50 TONMYA (cyclobenzaprine hydrochloride sublingual tablets) INDICATION: TONMYA is indicated for the treatment of fibromyalgia in adults. Important Safety Information (1 of 2) IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS TONMYA is contraindicated: In patients with hypersensitivity to cyclobenzaprine or any inactive ingredient in TONMYA. Hypersensitivity reactions may man ife st 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 disturb anc es, or congestive heart failure. In patients with hyperthyroidism. WARNINGS AND PRECAUTIONS Embryofetal toxicity: Based on animal data, TONMYA may cause neural tube defects when used two weeks prior to conception and during the first trime st er 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 pregnanc y t est 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 (S NRIs), tricyclic antidepressants, tramadol, bupropion, meperidine, verapamil, or MAO inhibitors increases the risk of serotonin syndrome, a potentially life - threatening condition. Serotonin syndr ome symptoms may include mental status changes, autonomic instability, neuromuscular abnormalities, and/or gastrointestinal symptoms. Treatment with TONMYA and any concomitant serotonergic agent should be disco nti nued 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, car efu l 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, prolongat io n of the conduction time leading to myocardial infarction and stroke. If clinically significant central nervous system (CNS) symptoms develop, consider discontin uat ion 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 durin g T CA 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 intra ocular pressure, and in patients taking anticholinergic drugs. CNS depression and risk of operating a motor vehicle or hazardous machinery: TONMYA monotherapy may cause CNS depression. Con com itant use of TONMYA with alcohol, barbiturates, or other CNS depressants may increase the risk of CNS depression. Advise patients not to operate a motor vehicle or dangerous machinery until they are rea son ably certain that TONMYA therapy will not adversely affect their ability to engage in such activities. Oral mucosal adverse reactions: In clinical studies with TONMYA, oral mucosal adverse reactions occurred more frequently in patients treated with TONMYA comp ar ed to placebo. Advise patients to moisten the mouth with sips of water before administration of TONMYA to reduce the risk of oral sensory ch ang es (hypoesthesia). Consider discontinuation of TONMYA if severe reactions occur.
© 2025 Tonix Pharmaceuticals Holding Corp. 51 TONMYA (cyclobenzaprine hydrochloride sublingual tablets) INDICATION: TONMYA is indicated for the treatment of fibromyalgia in adults. Important Safety Information (2 of 2) IMPORTANT SAFETY INFORMATION (CONT’D) ADVERSE REACTIONS The most common adverse reactions (incidence ≥2% and at a higher incidence in TONMYA - treated patients compared to placebo - treate d patients) were oral hypoesthesia, oral discomfort, abnormal product taste, somnolence, oral paresthesia, oral pain, fatigue, dry mouth, and aphthous ulcer. DRUG INTERACTIONS MAO inhibitors: Life - threatening interactions may occur. Other serotonergic drugs: Serotonin syndrome has been reported. CNS depressants: CNS depressant effects of alcohol, barbiturates, and other CNS depressants may be enhanced. Tramadol: Seizure risk may be enhanced. Guanethidine or other similar acting drugs: The antihypertensive action of these drugs may be blocked. USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, TONMYA may cause fetal harm when administered to a pregnant woman. The limited amount of availa ble observational data on oral cyclobenzaprine use in pregnancy is of insufficient quality to inform a TONMYA - associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Advise pr egnant women about the potential risk to the fetus with maternal exposure to TONMYA and to avoid use of TONMYA two weeks prior to conception and through the first trimester of pregnancy. Report pregnancies to the Ton ix Medicines, Inc., adverse - event reporting line at 1 - 888 - 869 - 7633 (1 - 888 - TNXPMED). Lactation: A small number of published cases report the transfer of cyclobenzaprine into human milk in low amounts, but these da ta cannot be confirmed. There are no data on the effects of cyclobenzaprine on a breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along wit h the mother’s clinical need for TONMYA and any potential adverse effects on the breastfed child from TONMYA or from the underlying maternal condition. Pediatric use: The safety and effectiveness of TONMYA have not been established. Geriatric patients: Of the total number of TONMYA - treated patients in the clinical trials in adult patients with fibromyalgia, n one were 65 years of age and older. Clinical trials of TONMYA did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients. Hepatic impairment: The recommended dosage of TONMYA in patients with mild hepatic impairment (HI) (Child Pugh A) is 2.8 mg once daily at bedtime, lower than the recommended dosage in patients with normal hepatic function. The use of TONMYA is not recommended in patients with moderate HI (Child Pugh B) or severe HI (Child Pugh C). Cyclo ben zaprine exposure (AUC) was increased in patients with mild HI and moderate HI compared to subjects with normal hepatic function, which may increase the risk of TONMYA - associated adverse reactions.
