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.
Please
see additional safety information in the full Prescribing Information. To report suspected adverse reactions, contact Tonix
Medicines, Inc. at 1-888-869-7633, or the FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.
