    2.3 Recommended Dosage in Patients with Hepatic Impairment

    The recommended TONMYA dosage―and the maximum recommended dosage―in patients with mild hepatic impairment is 2.8 mg administered sublingually once daily at bedtime. TONMYA is not recommended in patients with moderate or severe hepatic impairment [see Use in Specific Populations (8.6)].

    2.4 Administration Instructions

    TONMYA is only for sublingual use.

    • Administer after brushing teeth and finishing other oral care and ensure a moist mouth/sublingual area by drinking a few sips of water prior to administration.
    • Place the sublingual tablet(s) under the tongue until dissolved.
    • Do not swallow whole, cut, crush, or chew.
    • Avoid eating or drinking for at least 15 minutes after the sublingual tablet(s) has/have completely dissolved at bedtime and preferably avoid any hot, cold, or acidic beverages until the morning.
    • Avoid talking for at least 5 minutes after administration.

    2.5 Recommendations Regarding Missed Dose(s)

    If you missed a TONMYA bedtime dose, take TONMYA the next evening. Do not take a missed dose during the day.

    2.6 Pregnancy Testing Prior to Administration

    Pregnancy testing is recommended in females of reproductive potential prior to initiating treatment with TONMYA [see Warnings and Precautions (5.1), and Use in Specific Populations (8.1, 8.3)]

  • 3 DOSAGE FORMS AND STRENGTHS

    Sublingual tablets: 2.8 mg of cyclobenzaprine hydrochloride - yellow and round with the letter "T" debossed on one face.

  • 4 CONTRAINDICATIONS

    • 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.
    • Concomitant use of monoamine oxidase (MAO) inhibitors or within 14 days after discontinuation of a 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.
    • Hyperthyroidism.
  • 5 WARNINGS AND PRECAUTIONS

    5.1 Embryofetal Toxicity

    Based on data from animal reproduction studies, TONMYA may cause an increased risk of neural tube defects when administered to a pregnant female two weeks prior to conception and during the first trimester of pregnancy. Neural tube defects (splayed vertebral arches and spina bifida occulta) were observed in a rabbit embryofetal development study at the highest maternal dose tested, in the absence of maternal toxicity. Because neural tube development occurs early in pregnancy, often before pregnancy is recognized, advise females of reproductive potential of the potential risk to the fetus and avoid use of TONMYA two weeks prior to conception and through the first trimester of pregnancy.

    Perform a pregnancy test prior to initiation of treatment with TONMYA to exclude use of TONMYA during the first trimester of pregnancy.

    Advise females of reproductive potential to use effective contraception during TONMYA treatment and for two weeks after the final dose [see Use in Specific Populations (8.1, 8.3)].

    5.2 Serotonin Syndrome

    The development of a potentially life-threatening serotonin syndrome has been reported with cyclobenzaprine when used in combination with other drugs, such as selective serotonin reuptake inhibitors (SSRIs), serotonin norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), tramadol, bupropion, meperidine, verapamil, or MAO inhibitors. The concomitant use of TONMYA with MAO inhibitors is contraindicated [see Contraindications (4)].

    Serotonin syndrome symptoms may include mental status changes (e.g., confusion, agitation, hallucinations), autonomic instability (e.g., diaphoresis, tachycardia, labile blood pressure, hyperthermia), neuromuscular abnormalities (e.g., tremor, ataxia, hyperreflexia, clonus, muscle rigidity), and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).

    Treatment with TONMYA and any concomitant serotonergic agents 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.

    5.3 Tricyclic Antidepressant-like Adverse Reactions

    Cyclobenzaprine is structurally related to tricyclic antidepressants (TCAs).

    TCAs have been reported to produce arrhythmias, sinus tachycardia, prolongation of the conduction time leading to myocardial infarction and stroke [see Contraindications (4)].

    Some of the more TCA-associated serious central nervous system (CNS) reactions have occurred in short-term studies of oral cyclobenzaprine. If clinically significant 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 increase in frequency of seizures.

    5.4 Atropine-like Adverse Reactions

    Because of its atropine-like action, TONMYA should be used with caution in patients with a history of urinary retention, angle-closure glaucoma, increased intraocular pressure, and in patients taking anticholinergic drugs.

    5.5 CNS Depression and Risk of Operating a Motor Vehicle or Hazardous Machinery

    TONMYA monotherapy may cause CNS depression and concomitant use of TONMYA with alcohol, barbiturates, or other CNS depressants may increase the risk of CNS depression [see Drug Interactions (7)].

    Symptoms of CNS depression include somnolence. 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.

    5.6 Oral Mucosal Adverse Reactions

    Oral mucosal adverse reactions, including sensory changes (e.g., numbness, tingling), discomfort, pain, irritation, inflammation, and lesions, occurred more frequently in patients treated with TONMYA compared to placebo (43% vs. 8%) [see Adverse Reactions (6.1)]. Reactions typically occurred within minutes of administration and most resolved within 60 minutes.

    Five patients experienced severe oral mucosal adverse reactions, including sensory changes (paresthesia, hypoesthesia), inflammation (glossitis), oral pain, and dry mouth. Most severe oral mucosal adverse reactions resolved within days after TONMYA was discontinued and no treatment was required.

    Advise patients to moisten the mouth with sips of water before administration of TONMYA to reduce the risk of oral sensory changes (hypoesthesia). Advise patients to report severe oral mucosal adverse reactions to their healthcare provider. Consider discontinuation of TONMYA if severe reactions occur.

  • 6 ADVERSE REACTIONS

    The following clinically significant reactions are described in greater detail, in other sections of this labeling:

    6.1 Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

    The safety of sublingual TONMYA (14 days of 2.8 mg once daily and then 5.6 mg once daily thereafter) is supported by three double-blind, placebo-controlled clinical trials (Trials 1, 2, and 3) in adult patients with fibromyalgia [see Clinical Studies (14)]. A total of 1,182 patients completed at least 14 weeks of daily treatment, including 580 TONMYA-treated patients (14 days of 2.8 mg once daily and then 5.6 mg once daily thereafter) and 602 placebo-treated patients.

    Table 1 summarizes the most common adverse reactions in Trials 1, 2, and 3 (≥2% of TONMYA-treated patients and at a higher incidence in TONMYA-treated patients compared to placebo-treated patients).

    Oral Mucosal Adverse Reactions in Trials 1, 2, and 3

    In Trials 1, 2, and 3, 43% of TONMYA-treated patients compared to 8% of placebo-treated patients experienced at least 1 treatment-emergent oral mucosal adverse reaction. The most common oral mucosal adverse reactions included oral hypoesthesia, abnormal product taste, oral paresthesia, tongue discomfort, oral discomfort, glossodynia, oral pain, and aphthous ulcer. The majority (82%) of oral mucosal adverse reactions began within minutes of dosing, and of those, 88% occurred after nearly every dose. Almost two-thirds lasted less than 60 minutes. Of the approximately one-third that lasted longer than 60 minutes, 63% were present the next morning.

    Five patients (0.7% of TONMYA-treated patients) experienced severe oral mucosal adverse reactions, including paresthesia, glossitis, hypoesthesia, oral pain, and dry mouth. Most reactions resolved within days after TONMYA was discontinued. Oral mucosal adverse reactions leading to discontinuation occurred more frequently in TONMYA-treated patients compared to placebo-treated patients (4.5% vs. 0.5%).

    Adverse Reactions from Other Trials

    In an open-label, long-term 40 to 52-week safety trial (Trial 4) in an unapproved population of patients previously exposed to 5.6 mg TONMYA once daily (maximum recommended dosage) or placebo, 56 patients were treated with 5.6 mg of TONMYA for at least 1 year. The most common adverse reactions in the TONMYA-treated patients (>5%) were oral hypoesthesia (45%), somnolence (18%), abnormal product taste (7%), and paresthesia oral (7%).

    In an open-label, long-term 52 week safety trial of adult patients with fibromyalgia previously been exposed to 2.8 mg TONMYA once daily (one half the recommended dosage [see Dosage and Administration (2.1)]) or placebo (Trial 5), 97 patients were treated for at least 1 year with 2.8 mg of TONMYA once daily. The most common adverse reactions (>5%) in the TONMYA-treated patients were hypoesthesia oral (15%), fatigue (7%), sinusitis (7%), and abnormal product taste (6%).

    6.2 Postmarketing Experience

    The following adverse reactions have been reported in clinical studies or postmarketing experience with cyclobenzaprine immediate-release (IR) products, cyclobenzaprine extended-release (ER) products, or TCAs. Because some of these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

    In a postmarketing surveillance program of cyclobenzaprine IR products, the adverse reactions reported most frequently were drowsiness, dry mouth, and dizziness, and adverse reactions reported in 1% to 3% of the patients were: fatigue/tiredness, asthenia, nausea, constipation, dyspepsia, unpleasant taste, blurred vision, headache, nervousness, and confusion.

    The following adverse reactions have been reported in postmarketing experience with cyclobenzaprine ER products or cyclobenzaprine IR products, in clinical studies of cyclobenzaprine IR products (incidence <1%), or in postmarketing experience with other TCAs:

    Body as a Whole: Syncope; malaise; chest pain; edema.

  • 7 DRUG INTERACTIONS

    Based on its structural similarity to TCAs, concomitant use of TONMYA with:

    • MAO inhibitors may be life-threatening [see Contraindications (4)],
    • Alcohol, barbiturates, and other CNS depressants may increase the risk of adverse reactions associated with these drugs,
    • Tramadol may increase the seizure risk,
    • Guanethidine or other similar acting drugs may block the antihypertensive action of these drugs.

    Postmarketing cases of serotonin syndrome have been reported with the concomitant use of oral cyclobenzaprine and other drugs, such as SSRIs, SNRIs, TCAs, tramadol, bupropion, meperidine, verapamil, or MAO inhibitors [see Warnings and Precautions (5.2)].

    • The concomitant use of TONMYA with MAO inhibitors is contraindicated. If serotonin syndrome symptoms occur with the use of other serotonergic drugs, immediately discontinue TONMYA.
    • If concomitant treatment with TONMYA and other serotonergic drugs (besides MAO inhibitors) is clinically warranted, careful observation is advised, particularly during dosage increases.
  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Based on animal data, TONMYA may cause fetal harm when administered to a pregnant woman. In rabbits, an increased incidence of neural tube defects (splayed vertebral arches and spina bifida occulta) was observed when pregnant rabbits were treated with oral cyclobenzaprine during embryogenesis with 30 mg/kg/day (approximately 0.2 times the maximum recommended human dose (MRHD) of TONMYA), in the absence of maternal toxicity. In rats, decreased pup body weight and survival were noted at a cyclobenzaprine dose of ≥10 mg/kg/day (approximately ≥0.8 times the MRHD of TONMYA), when administered orally during pregnancy and lactation (see Data). 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.

    The background risk of major birth defects and miscarriage for pregnant women with fibromyalgia is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

    Data

    Animal Data:

    Oral administration of cyclobenzaprine during organogenesis to rabbits at the highest maternal dose of 30 mg/kg/day (approximately 0.2 times the MRHD of 5.6 mg/day of TONMYA on an AUC basis) increased the incidence of neural tube defects (splayed vertebral arches and spina bifida occulta) in the absence of maternal toxicity. The no effect level for embryo-fetal development in rabbits was 10 mg/kg/day (approximately 0.05 times the MRHD of TONMYA on an AUC basis).

    In another study, no adverse embryofetal effects were reported following oral administration of cyclobenzaprine during organogenesis to rabbits at maternal doses up to 20 mg/kg/day (approximately 0.1 times the MRHD of TONMYA on an estimated AUC basis).

    No adverse embryofetal effects were reported following oral administration of cyclobenzaprine during organogenesis to rats at doses up to 25 mg/kg/day (approximately 9.2 times the MRHD of TONMYA, on an AUC basis). Maternal toxicity characterized by decreased body weight gain was observed in rats at this dose of 25 mg/kg/day.

    No adverse embryofetal effects were reported following oral administration of cyclobenzaprine during organogenesis to mice at maternal doses up to 20 mg/kg/day (approximately 17 times the MRHD of TONMYA on a mg/m2 basis). Maternal toxicity characterized by decreased body weight gain was observed at the highest tested dose of 20 mg/kg/day.

    Decreased pup body weight and survival were reported in a prenatal and postnatal study where pregnant rats were treated orally with cyclobenzaprine during pregnancy and lactation with maternal doses of 10 and 20 mg/kg/day (approximately 0.8 and 1.7 times the MRHD of TONMYA on an estimated AUC basis). Maternal toxicity, characterized by a decreased body weight gain, was observed only at the highest tested dose of 20 mg/kg/day.

    In another prenatal and postnatal study where pregnant rats were treated orally with cyclobenzaprine during pregnancy and lactation with maternal doses up to 10 mg/kg/day (approximately 0.8 times the MRHD of TONMYA on an AUC basis) no adverse effects were reported in maternal animals and offspring.

    8.2 Lactation

    Risk Summary

    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.

    8.3 Females and Males of Reproductive Potential

    Based on animal data, TONMYA may cause neural tube defects at clinically relevant doses. Females of reproductive potential should avoid use of TONMYA two weeks prior to conception through the first trimester of pregnancy [see Use in Specific Populations (8.1)].

    Pregnancy Testing

    Pregnancy testing is recommended for females of reproductive potential prior to initiation of treatment with TONMYA.

    Contraception

    Females

    Advise female patients of reproductive potential to use effective contraception during treatment with TONMYA and for two weeks after the final dose.

    8.4 Pediatric Use

    The safety and effectiveness of TONMYA have not been established in pediatric patients.

    8.5 Geriatric Use

    Of the total number of TONMYA-treated patients in the clinical trials in adult patients with fibromyalgia (Trials 1, 2, and 3) [see Clinical Studies (14)], 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.

    After administration of cyclobenzaprine extended release capsules, the plasma concentration and half-life of cyclobenzaprine were substantially increased in the subjects 65 years of age and older compared to those under 65 years of age [see Clinical Pharmacology (12.3)]. Given the higher cyclobenzaprine exposure in patients 65 years of age and older, the recommended TONMYA dosage in patients 65 years of age and older is 2.8 mg once daily at bedtime, lower than the recommended dosage in younger adult patients [see Dosage and Administration (2.2)].

    8.6 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 [see Dosage and Administration (2.2)]. 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 [see Clinical Pharmacology (12.3)], which may increase the risk of TONMYA-associated adverse reactions.

  • 9 DRUG ABUSE AND DEPENDENCE

    9.1 Controlled Substance

    TONMYA contains cyclobenzaprine, which is not a controlled substance.

    9.3 Dependence

    Given the pharmacologic similarities among the TCAs, consider withdrawal symptoms when stopping TONMYA. Abrupt cessation of TONMYA treatment after prolonged administration may produce nausea, headache, and malaise. These are not indicative of addiction.

  • 10 OVERDOSAGE

    Overdose Signs, Symptoms, and Complications of Cyclobenzaprine Overdose

    • The most common adverse reactions associated with cyclobenzaprine overdose are drowsiness and tachycardia.
    • Less frequent overdose manifestations include tremor, agitation, coma, ataxia, hypertension, slurred speech, confusion, dizziness, nausea, vomiting, and hallucinations.
    • Rare but potentially critical overdose manifestations that have been reported are cardiac arrest, chest pain, cardiac dysrhythmias, severe hypotension, seizures, cases of neuroleptic malignant syndrome and rhabdomyolysis, and death.

    Changes in the electrocardiogram, particularly in QRS axis or width, are clinically significant indicators of cyclobenzaprine toxicity. Other potential cyclobenzaprine overdosage adverse reactions include any of the adverse reactions listed under Adverse Reactions (6).

    Multiple drug ingestion (including alcohol) is common in deliberate cyclobenzaprine overdose.

    Treatment of Cyclobenzaprine Overdose

    Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.

    Signs and symptoms of toxicity may develop rapidly after cyclobenzaprine overdose; therefore, hospital monitoring is recommended as soon as possible. To reduce the risk of rare but potentially critical cyclobenzaprine overdose manifestations, obtain an ECG and immediately initiate cardiac monitoring. Protect the patient's airway and establish an intravenous line. Recommend observation with cardiac monitoring and observation for signs of CNS or respiratory depression, hypotension, cardiac dysrhythmias and/or conduction blocks, and seizures.

    Monitoring of plasma cyclobenzaprine levels should not guide overdose management of the patient. Dialysis is probably of no value because of low plasma concentrations of cyclobenzaprine.

    Treatment of Cardiovascular Overdosage Complications: A maximal limb-lead QRS duration of 0.1 seconds may be the best indication of the severity of the cyclobenzaprine overdose.

    Serum alkalinization, to a pH of 7.45 to 7.55, using intravenous sodium bicarbonate and hyperventilation (as needed), should be instituted for patients with dysrhythmias and/or QRS widening. A pH >7.6 or a pCO2 <20 mmHg is undesirable. Dysrhythmias unresponsive to sodium bicarbonate therapy/hyperventilation may respond to lidocaine or phenytoin. Type 1A and 1C antiarrhythmics (e.g., quinidine, disopyramide, and procainamide) are generally contraindicated in the setting of a cyclobenzaprine overdose.

    Treatment of CNS Overdosage Complications: In patients with CNS depression associated with a cyclobenzaprine overdose, early intubation is advised because of the potential for abrupt deterioration. Seizures should be controlled with benzodiazepines or, if these are ineffective, other anticonvulsants (e.g., phenobarbital, phenytoin). Physostigmine is not recommended except to treat life-threatening symptoms that have been unresponsive to other therapies, and then only in close consultation with a poison center.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    The mechanism of action of cyclobenzaprine for the treatment of fibromyalgia in adults is unknown. In in vitro pharmacology studies, cyclobenzaprine demonstrated functional antagonism of 5-HT2A, α1-adrenergic, H1-histaminergic, and M1-muscarinic acetylcholine receptors. In addition, pharmacological studies in animals demonstrated a similarity between the effects of cyclobenzaprine and the structurally related TCAs, including reserpine antagonism, norepinephrine potentiation, potent peripheral and central anticholinergic effects, and sedation.

    12.2 Pharmacodynamics

    The exposure-response relationship and time course of pharmacodynamic response for the safety and effectiveness of cyclobenzaprine have not been fully characterized.

    12.3 Pharmacokinetics

    Following single-dose sublingual administration of 2.8 mg and 5.6 mg of TONMYA in healthy adult subjects (n=16), Cmax, AUC0-tau, and AUC0-inf of cyclobenzaprine increased in an approximately dose-proportional manner.

    In a multiple-dose study of 5.6 mg of TONMYA administered sublingually once daily for 20 days in healthy subjects (n=26), approximately 2.5-fold accumulation of plasma cyclobenzaprine exposure was observed at steady-state.

    Absorption

    The median time to peak plasma cyclobenzaprine concentration (Tmax) was approximately 4.3 hours for the 2.8 mg and 5.6 mg once daily TONMYA dosages.

    Food Effect: A food effect study was conducted in healthy adult subjects (n=16) with a single sublingual 5.6 mg TONMYA dose. When TONMYA was administered with food, there was approximately 10% decrease in peak plasma concentration (Cmax) compared to the fasted state with no effect on exposure (AUC0-tau and AUC0-inf). These changes are not clinically significant.

    Elimination

    TONMYA has a single dose elimination half-life of approximately 36 hours (range 28-59 hours; n=16).

    Metabolism: Cyclobenzaprine is extensively metabolized. Cytochromes P-450 3A4, 1A2, and, to a lesser extent, 2D6 mediate N-demethylation, one of the oxidative pathways for cyclobenzaprine metabolism.

    Excretion: Cyclobenzaprine is excreted primarily as glucuronides via the kidney.

    Specific Populations

    Geriatric Patients: After cyclobenzaprine extended-release capsules dosing, the plasma cyclobenzaprine AUC was increased by 40% and the half-life of cyclobenzaprine was prolonged in geriatric subjects greater than 65 years of age compared to younger adult subjects 18 to 45 years of age (50 hours vs. 32 hours, respectively) [see Use in Specific Populations (8.5)]. There were no notable differences in Cmax or Tmax in this study.

    Hepatic Impairment: In a pharmacokinetic study of immediate-release cyclobenzaprine tablets in 15 patients with mild hepatic impairment (HI) (Child-Pugh A) and 1 patient with moderate HI (Child-Pugh B), both AUC and Cmax were approximately double the values seen in subjects with normal hepatic function. The pharmacokinetics of cyclobenzaprine in patients with moderate HI (1 patient only) and severe HI is not known [see Use in Specific Populations (8.6)].

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis

    Long-term studies were conducted in CD-1 mice and Sprague-Dawley rats with oral cyclobenzaprine to evaluate its carcinogenic potential. In an 81-week carcinogenicity study, metastatic hemangiosarcoma was seen in 3 of 21 male mice at 10 mg/kg/day (approximately 9 times the maximum recommended human dose (MRHD) of 5.6 mg of TONMYA on a mg/m2 basis). In a 105-week carcinogenicity study, malignant astrocytoma was seen in 3 of 50 male rats at 10 mg/kg/day (approximately 0.3 times the MRHD on an estimated AUC basis). There were no tumor findings in female mice or rats.

    Mutagenesis

    Cyclobenzaprine was not mutagenic or clastogenic in the following assays: in vitro Ames bacterial mutation assays, an in vitro Chinese hamster ovary (CHO) cell chromosomal aberration test, an in vitro CHO cell micronucleus test, and in vivo mouse bone marrow micronucleus assays.

    Impairment of Fertility

    Cyclobenzaprine HCl, when administered 70 and 14 days prior to mating to male and female rats, respectively, had no effects on fertility or reproductive performance at oral doses up to 20 mg/kg/day (approximately 1.1 and 3.8 times in males and females, respectively, the MRHD on an estimated AUC basis).

    13.2 Animal Toxicology and/or Pharmacology

    In a 67-week study with rats that received cyclobenzaprine at oral doses of 10, 20, or 40 mg/kg/day (approximately 0.3 to 4.3 times and 1.2 to 12.4 times in males and females, respectively, the maximum recommended human dose (MRHD) of 5.6 mg of TONMYA on an estimated AUC basis), there were findings in the liver consisting of midzonal vacuolation with lipidosis for males and midzonal and centrilobular hepatocytic enlargement for females. In addition, there were findings of centrilobular coagulative necrosis. In the higher dose groups, these microscopic changes were seen after 26 weeks and even earlier in rats that died prior to 26 weeks; at lower doses, these changes were not seen until after 26 weeks.

    In a 26-week study with Cynomolgus monkeys that received cyclobenzaprine at oral of doses of 2.5, 5, 10, or 20 mg/kg/day, one monkey at 20 mg/kg/day (69 times the MRHD on mg/m2 basis) was euthanized in week 17. Morbidity for this animal was attributed to findings of chronic pancreatitis, cholecystitis, cholangitis, and focal liver necrosis.

  • 14 CLINICAL STUDIES

    The efficacy of TONMYA for the treatment of fibromyalgia was assessed in three randomized, two-arm, parallel-group, double-blind, placebo-controlled multicenter trials (Trial 1 [NCT04172831], Trial 2 [NCT04508621], and Trial 3 [NCT05273749]). The trials enrolled 1,474 patients aged 18 to 65 (735 TONMYA-treated patients and 739 placebo-treated patients) who met the 2016 American College of Rheumatology (ACR) criteria for diagnosis of fibromyalgia (including generalized pain, defined as pain in at least 4 of 5 regions; symptoms that had been present at a similar level for at least 3 months; and widespread pain index (WPI) ≥7 and symptom severity scale (SSS) score ≥5, OR WPI between 4 to 6 and SSS scale score ≥9). In the trials, 95% of patients were female, 83% of patients were not Hispanic or Latino, and the percentage of White, Black, and Asian patients were 86%, 9%, and 1%, respectively. The mean age was 49 years (range 18 to 65 years), and the mean duration of fibromyalgia was 9 years (range 0 to 49 years).

    Patients were randomized to receive bedtime sublingual treatment of either:

    • 2.8 mg of TONMYA nightly for the first 2 weeks, and then 5.6 mg of TONMYA beginning on the evening of Day 15 through Week 14.
    • Placebo administered through Week 14.

    The primary endpoint in all three trials was the change from baseline to Week 14 in the weekly average of daily 24-hour recall pain intensity scores.

    As measured by the 11-point (0-10) numeric rating scale (NRS), the minimum mean baseline pain score required for enrollment was 4. Within each trial, at baseline, the TONMYA and placebo groups had similar mean weekly averages of daily diary pain scores.

    • In Trials 1 and 3, TONMYA demonstrated a statistically significant reduction in pain intensity scores as compared to placebo (Table 2).
    • In Trial 2, there was no statistically significant treatment group difference (TONMYA minus placebo). Results of this trial may not have been generalizable due to the presence of factors outside the conduct of the study.

    The least squares (LS) mean change from baseline in the weekly average of daily 24-hour recall pain intensity scores at Week 14 in adult patients with fibromyalgia for the TONMYA and placebo groups in Trial 1 and Trial 3 are presented in Table 2. The LS mean change from baseline in the weekly average of daily 24-hour recall pain intensity scores over the weeks of the study in adult patients with fibromyalgia in Trials 1 and 3 are presented in Figure 1.

    Figure 2 shows the percentage of patients in Trials 1 and 3 who achieved various degrees of improvement in the change from baseline to Week 14 in the weekly averages of daily diary pain scores. The figures are cumulative so that patients whose change from baseline is, for example, 50%, are also included at every level of improvement below 50%. Patients who did not complete the trial were assigned 0% improvement. For example, in Trial 1 and Trial 3, the percentage of TONMYA-treated patients who achieved at least a 30% improvement from baseline in their weekly average of daily 24-hour recall pain intensity score at Week 14 was 47% and 46%, respectively.
