WARNINGS
Included as part of the PRECAUTIONS section.
PRECAUTIONS
Skin Irritation
Patients using AKLIEF Cream may experience erythema,
scaling, dryness, and stinging/burning. Maximum severity of these reactions
typically occurred within the first 4 weeks of treatment, and severity
decreased with continued use of the medication. Depending upon the severity of
these adverse reactions, instruct patients to use a moisturizer, reduce the
frequency of application of AKLIEF Cream, or suspend use temporarily. If severe
reactions persist the treatment may be discontinued.
Avoid application of AKLIEF to cuts, abrasions, or
eczematous or sunburned skin. Use of “waxing” as a depilatory method should be
avoided on skin treated with AKLIEF Cream.
Ultraviolet Light And Environmental Exposure
Minimize unprotected exposure to ultraviolet rays
(including sunlight and sunlamps) during treatment with AKLIEF. Warn patients
who normally experience high levels of sun exposure and those with inherent
sensitivity to sun to exercise caution. Use of sunscreen products and
protective clothing over treated areas is recommended when exposure cannot be
avoided.
Patient Counseling Information
See FDA-approved patient
labeling (PATIENT INFORMATION).
Advise the patient to:
- Cleanse the area to be treated;
pat dry. Apply AKLIEF Cream as a thin layer once daily in the evening to the
face, avoiding the eyes, lips, nasolabial folds, and mucous membranes. A thin layer of AKLIEF Cream may also be applied to
the chest, shoulders, and back.
- Avoid applying AKLIEF Cream to
damaged skin (such as cuts, abrasions), eczematous areas, and sunburned skin.
- Reduce the risk of such irritation, use a moisturizer
from the start of treatment, and, if appropriate, reduce the frequency of
application of AKLIEF Cream or suspend use temporarily. AKLIEF Cream may cause
irritation such as erythema, scaling, dryness, and stinging or burning.
- Minimize exposure to sunlight,
including sunlamps and phototherapy devices.
- Use sunscreen products and
protective apparel (e.g., hat) over treated areas when exposure to sunlight
cannot be avoided.
- Avoid concomitant use of other
potentially irritating topical products
(medicated or not).
- Use AKLIEF Cream on the
smallest area of skin and for the shortest duration possible while
breastfeeding. Advise breastfeeding women not
to apply AKLIEF Cream directly to the nipple and areola to avoid direct infant exposure.
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Trifarotene was not carcinogenic when topically applied
to mice daily for up to 24 months in the vehicle of the product (AKLIEF Cream)
at concentrations of 0.0005% or 0.001% w/w. The systemic exposures at the
highest doses evaluated in mice were approximately 82 (males) and 99 (females)
times higher than the human exposure at the MRHD of AKLIEF Cream.
Trifarotene was not carcinogenic when administered orally
to rats daily for up to 24 months at doses up to 0.75 mg/kg/day in males and
0.2 mg/kg/day in females. The systemic exposures at the highest doses evaluated
in rats were approximately 645 (males) and 1642 (females) times higher than the
human exposure at the MRHD of AKLIEF Cream.
Trifarotene was negative in an in vitro bacterial reverse
mutation (Ames) assay, an in vitro micronucleus assay in primary human
lymphocytes, an in vitro mouse lymphoma assay with L5178Y/TK+/- cells, and an
in vivo micronucleus assay in rats.
Trifarotene was assessed for effects on fertility or
general reproductive function in rats. Males received trifarotene via oral
gavage for 4 weeks prior to mating, during mating, and up to scheduled
termination (approximately 6 weeks in total), and females were treated via oral
gavage for 2 weeks prior to mating through Day 7 of gestation. No adverse
effects on fertility or reproductive parameters, including sperm motility and
concentration, were observed at the highest doses evaluated, which resulted in
systemic exposures approximately 1755 (males) and 1726 (females) times higher
than the human exposure at the MRHD of AKLIEF Cream.
Use In Specific Populations
Pregnancy
Risk Summary
Available data from clinical trials with AKLIEF Cream use
in pregnant women have not identified a drug-associated risk of major birth
defects, miscarriage or adverse maternal or fetal outcomes. There are case
reports of major birth defects similar to those seen in fetuses exposed to oral
retinoids in pregnant women exposed to other topical retinoids, but these case
reports do not establish a pattern or association with retinoid-related
embryopathy.
In animal reproduction studies, oral doses of trifarotene
administered to pregnant rats and rabbits during organogenesis that resulted in
systemic exposures more than 800 times the systemic exposure at the maximum
recommended human dose (MRHD) of AKLIEF Cream resulted in adverse fetal
effects, including fetal deaths and external, visceral, and skeletal
malformations (see Data). The background risk of major birth defects and
miscarriage for the indicated population is unknown. All pregnancies have a
background risk of birth defect, loss, or other adverse outcomes. In the US
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 trifarotene to pregnant rats
during the period of organogenesis at doses that resulted in systemic exposures
greater than 1600 times those in humans at the MRHD of AKLIEF Cream resulted in
adverse fetal effects, including fetal deaths, reduced mean fetal weight, and
external, visceral, and skeletal malformations.
Oral administration of trifarotene to pregnant rabbits
during the period of organogenesis at doses that resulted in systemic exposures
at least 800 times those in humans at the MRHD of AKLIEF Cream resulted in
adverse fetal effects, including defects of the tail, limbs, urogenital organs,
and vertebral column.
Trifarotene administered orally to female rats from
gestation Day 6 to lactation Day 20, at doses that resulted in systemic
exposures up to 594 times those in humans at the MRHD of AKLIEF Cream, had no
effect on maternal function or behavior, including gestation, delivery,
pup-rearing, lactation and nursing, or survival or development of pups. There
were no effects of maternal treatment on behavior, learning, memory, or
reproductive function of pups.
Lactation
Risk Summary
There are no data on the presence of trifarotene in human
milk, the effects on the breastfed infant, or the effects on milk production.
In animal studies, trifarotene was present in rat milk with oral administration
of the drug. When a drug is present in animal milk, it is likely that the drug
will be present in human milk. It is possible that topical administration of
large amounts of trifarotene could result in sufficient systemic absorption to
produce detectable quantities in human milk (see Clinical Considerations).
The developmental and health benefits of breastfeeding should be considered
along with the motherâ⬙s clinical need for AKLIEF Cream and any potential
adverse effects on the breastfed infant from AKLIEF Cream or from the
underlying maternal condition.
Clinical Considerations
To minimize potential exposure to the breastfed infant
via breastmilk, use AKLIEF Cream on the smallest area of skin and for the
shortest duration possible while breastfeeding. Advise breastfeeding women not
to apply AKLIEF Cream directly to the nipple and areola to avoid direct infant
exposure.
Pediatric Use
Safety and effectiveness of AKLIEF Cream for the topical
treatment of acne vulgaris have been established in pediatric patients age 9
years to 17 years based on evidence from well-controlled clinical trials, a
long-term safety trial, and a pharmacokinetic trial. A total of 897 pediatric
subjects aged 9 to 17 years received AKLIEF Cream in the clinical trials [see CLINICAL
PHARMACOLOGY and Clinical Studies].
Safety and effectiveness of AKLIEF Cream have not been
established in pediatric subjects under the age of 9 years.
Geriatric Use
Clinical trials of AKLIEF Cream did not include any
subjects aged 65 years and over to determine whether they respond differently
than younger subjects.
