On August 15, 2025, Tonix Pharmaceuticals Holding Corp. (the “Company”) announced that the U.S. Food and Drug Administration (“FDA”) approved TonmyaTM (cyclobenzaprine HCl sublingual tablets), which was investigated as TNX-102 SL, for the treatment of fibromyalgia in adults. Tonmya is expected to be available for adult patients in the U.S. with fibromyalgia beginning in the fourth quarter of 2025. A copy of the press release which discusses this matter is furnished hereto as Exhibit 99.01, and incorporated herein by reference.
The Company will host a webcast and conference call on August 18, 2025 at 8:30 a.m. Eastern Time to discuss the approval. Instructions on how to access the webcast and conference call are included in the press release furnished as Exhibit 99.1 hereto.
The information in this Item 7.01 of this Current Report on Form 8-K, including Exhibit 99.01 attached hereto, shall not be deemed “filed” for purposes of Section 18 of the United States Securities Exchange Act of 1934 (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall they be deemed incorporated by reference in any filing under the United States Securities Act of 1933 or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.
| Item 8.01. | Other Events. |
On August 15, 2025, the Company announced that the FDA approved Tonmya for the treatment of fibromyalgia in adults. Tonmya is expected to be available for adult patients in the U.S. with fibromyalgia beginning in the fourth quarter of 2025. The approval incorporated efficacy data from two double-blind, randomized, placebo-controlled, Phase 3 clinical trials of an aggregate of 1,000 patients that evaluated Tonmya as a bedtime treatment for fibromyalgia. Across both Phase 3 trials, Tonmya significantly reduced daily pain scores compared to placebo at 14 weeks, the primary endpoint. Additionally, a greater percentage of study participants taking Tonmya experienced a clinically meaningful (≥30%) improvement in their pain after three months, compared to placebo. Across three Phase 3 clinical trials with over 1,400 patients evaluated, Tonmya was generally well tolerated. The most common adverse events (incidence ≥2% and at a higher incidence in Tonmya-treated patients compared to placebo-treated patients) included oral hypoesthesia, oral discomfort, abnormal product taste, somnolence, oral pain, fatigue, dry mouth and aphthous ulcer.
IMPORTANT SAFETY INFORMATION
INDICATION
TONMYA is indicated for the treatment of fibromyalgia in adults.
CONTRAINDICATIONS
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. |
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 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 (CNS) 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. |
| · | CNS depression and risk of operating a motor vehicle or hazardous machinery: TONMYA monotherapy may cause CNS depression. Concomitant 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 reasonably 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 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. |
ADVERSE REACTIONS
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.
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 available 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 pregnant 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 Tonix 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 data 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 with 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, none 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). Cyclobenzaprine 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. |
