Overdosage of DIFFERIN
Information about signs, symptoms, and laboratory findings of acute ovedosage and the general principles of overdose treatment.10 OVERDOSAGE Chronic ingestion of the drug may lead to the same side effects as those associated with excessive oral intake of vitamin A.
Adverse reactions
Information about undesirable effects, reasonably associated with use of the drug, that may occur as part of the pharmacological action of the drug or may be unpredictable in its occurrence. Adverse reactions include those that occur with the drug, and if applicable, with drugs in the same pharmacologically active and chemically related class. There is considerable variation in the listing of adverse reactions. They may be categorized by organ system, by severity of reaction, by frequency, by toxicological mechanism, or by a combination of these.6 ADVERSE REACTIONS The most frequently reported (≥ 1%) adverse reactions were erythema, scaling, dryness, and/or burning/stinging. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Galderma Laboratories, L.P. at 1-866-735-4137 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reactions 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. In the multi-center, controlled clinical trial, signs and symptoms of local cutaneous irritation were monitored in 258 acne subjects who used DIFFERIN Gel once daily for 12 weeks. Of the subjects who experienced cutaneous irritation (erythema, scaling, dryness, and/or burning/stinging), the majority of cases were mild to moderate in severity, occurred early in treatment and decreased thereafter. The incidence of local cutaneous irritation with DIFFERIN Gel from the controlled clinical trial is provided in the following table: Table 1: Physician assessed local cutaneous irritation with DIFFERIN Gel Incidence of Local Cutaneous Irritation with DIFFERIN Gel (N = 253*) Maximum Severity Scores Higher Than Baseline Mild Moderate Severe Erythema 66 (26.1%) 33 (13.0%) 1 (0.4%) Scaling 110 (43.5%) 47 (18.6%) 3 (1.2%) Dryness 113 (44.7%) 43 (17.0%) 2 (0.8%) Burning/Stinging 72 (28.5%) 36 (14.2%) 9 (3.6%) * Total number of subjects with local cutaneous data for at least one post-Baseline evaluation Table 2: Patient reported local cutaneous reactions with DIFFERIN Gel DIFFERIN (adapalene) Gel Vehicle Gel N = 258 N = 134 Related* Adverse Reactions Dry Skin Skin Discomfort Desquamation 57 (22.1%) 36 (14%) 15 (5.8%) 4 (1.6%) 6 (4.5%) 2 (1.5%) 0 (0%) 0 (0%) * Selected adverse reactions defined by investigator as Possibly, Probably or Definitely Related The following adverse reactions occurred in less than 1% of subjects: acne flare, contact dermatitis, eyelid edema, conjunctivitis, erythema, pruritus, skin discoloration, rash, and eczema. In a one-year, open-label safety trial of 551 subjects with acne who received DIFFERIN Gel, the pattern of adverse reactions was similar to the 12-week controlled study. 6.2 Post-Marketing Experience The following adverse reactions have been identified during post approval use of adapalene: Immune system disorders: angioedema, face edema, lip swelling Skin disorders: application site pain Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate the frequency or establish a causal relationship to drug exposure.

Clinical pharmacology
Information about the clinical pharmacology and actions of the drug in humans.12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Adapalene binds to specific retinoic acid nuclear receptors but does not bind to cytosolic receptor protein. Biochemical and pharmacological profile studies have demonstrated that adapalene is a modulator of cellular differentiation, keratinization, and inflammatory processes. However, the significance of these findings with regard to the mechanism of action of adapalene for the treatment of acne is unknown. 12.2 Pharmacodynamics Clinical pharmacodynamic studies have not been conducted for DIFFERIN Gel. 12.3 Pharmacokinetics Systemic exposure of adapalene following topical application of DIFFERIN Gel was evaluated in a clinical trial. Sixteen acne subjects were treated once daily for 10 days with 2 grams of DIFFERIN Gel applied to the face, chest and back, corresponding to approximately 2 mg/cm 2 . Fifteen subjects had quantifiable (LOQ = 0.1 ng/mL) adapalene levels resulting in a mean C max of 0.553 ± 0.466 ng/mL on Day 10 of treatment. The mean AUC 0-24hr was 8.37 ± 8.46 ng.h/mL as determined in 15 of the 16 subjects on Day 10. The terminal apparent half-life, determined in 15 of 16 subjects, ranged from 7 to 51 hours, with a mean of 17.2 ± 10.2 hours. Adapalene was rapidly cleared from plasma and was not detected 72 hours after the last application for all but one subject. Exposure of potential circulating metabolites of adapalene was not measured. Excretion of adapalene appears to be primarily by the biliary route. In another clinical trial in subjects with moderate to moderately severe acne, DIFFERIN (adapalene) Gel, 0.3% or Adapalene Gel, 0.1% was applied to the face and optionally to the trunk, once daily for 12 weeks. Seventy-eight (78) subjects had plasma adapalene levels evaluated at Weeks 2, 8, and 12. Of the 209 plasma samples analyzed, adapalene concentrations were below the limit of detection (LOD = 0.15 ng/mL) of the method in all samples but three. For the three samples, traces of adapalene below the limit of quantification (LOQ = 0.25 ng/mL) of the method were found. One of these samples was taken at Week 12 from a male subject treated with DIFFERIN Gel, 0.3% who treated the face and the trunk for eight weeks (thereafter, only the face was treated). The second and third samples were from the Week 2 and 12 visits of a female subject treated with Adapalene Gel, 0.1% who treated only the face for 12 weeks. In this study, the average daily usage of product was 1 g/day.
Mechanism of action
Information about the established mechanism(s) of the drugÕs action in humans at various levels (for example receptor, membrane, tissue, organ, whole body). If the mechanism of action is not known, this field contains a statement about the lack of information.12.1 Mechanism of Action Adapalene binds to specific retinoic acid nuclear receptors but does not bind to cytosolic receptor protein.

Information about carcinogenic, mutagenic, or fertility impairment potential revealed by studies in animals. Information from human data about such potential is part of the warnings field.13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility No carcinogenicity, genotoxicity, or impairment of fertility studies were conducted with DIFFERIN Gel. Carcinogenicity studies with adapalene were conducted in mice at topical doses of 0.4, 1.3, and 4.0 mg/kg/day (1.2, 3.9, and 12 mg/m 2 /day) and in rats at oral doses of 0.15, 0.5, and 1.5 mg/kg/day (0.9, 3.0, and 9.0 mg/m 2 /day). The highest dose levels are 3.2 (mice) and 2.4 (rats) times the MRHD based on a mg/m 2 comparison. In the rat study, an increased incidence of benign and malignant pheochromocytomas reported in the adrenal medulla of male rats was observed. Adapalene was not mutagenic or genotoxic in vitro (Ames test, Chinese hamster ovary cell assay, or mouse lymphoma TK assay) or in vivo (mouse micronucleus test). In rat oral studies, 20 mg/kg/day adapalene (32 times the MRHD based on a mg/m 2 comparison) did not affect the reproductive performance and fertility of F 0 males and females or the growth, development, or reproductive function of F 1 offspring

Clinical studies
This field may contain references to clinical studies in place of detailed discussion in other sections of the labeling.14 CLINICAL STUDIES The safety and efficacy of once daily use of DIFFERIN Gel for treatment of acne vulgaris were assessed in one 12 week, multi-center, controlled, clinical trial, conducted in a total of 653 subjects 12 to 52 years of age with acne vulgaris of mild to moderate severity. All female subjects of child-bearing potential enrolled in the trial were required to have a negative urine pregnancy test at the beginning of the trial and were required to practice a highly effective method of contraception during the trial. Female subjects who were pregnant, nursing or planning to become pregnant were excluded from the trial. Subjects enrolled in the trial were Caucasian (72%), Hispanic (12%), African-American (10%), Asian (3%), and other (2%). An equal number of males (49.5%) and females (50.5%) enrolled. Success was defined as “Clear” or “Almost Clear” in the Investigator’s Global Assessment (IGA). The success rate, mean reduction, and percent reduction in acne lesion counts from Baseline after 12 weeks of treatment are presented in the following table: Table 3: Clinical study primary efficacy results at Week 12 DIFFERIN (adapalene) Gel, 0.3% Adapalene Gel, 0.1% Vehicle Gel N = 258 N = 261 N = 134 IGA Success Rate 53 (21%) 41 (16%) 12 (9%) Inflammatory Lesions Mean Baseline Count Mean Absolute (%) Reduction 27.7 14.4 (51.6%) 28.1 13.9 (49.7%) 27.2 11.2 (40.7%) Non-Inflammatory Lesions Mean Baseline Count Mean Absolute (%) Reduction 39.4 16.3 (39.7%) 41.0 15.2 (35.2%) 40.0 10.3 (27.2%) Total Lesions Mean Baseline Count Mean Absolute (%) Reduction 67.1 30.6 (45.3%) 69.1 29.0 (41.8%) 67.2 21.4 (33.7%)

Geriatric use
Information about any limitations on any geriatric indications, needs for specific monitoring, hazards associated with use of the drug in the geriatric population.8.5 Geriatric Use Clinical studies of DIFFERIN Gel did not include subjects 65 years of age and older to determine whether they respond differently than younger subjects. Safety and effectiveness in geriatric patients age 65 and above have not been established.
Labor and delivery
Information about the drug’s use during labor or delivery, whether or not the use is stated in the indications section of the labeling, including the effect of the drug on the mother and fetus, on the duration of labor or delivery, on the possibility of delivery-related interventions, and the effect of the drug on the later growth, development, and functional maturation of the child.8.2 Lactation Risk Summary There are no data on the presence of topical adapalene gel or its metabolite in human milk, the effects on the breastfed infant, or the effects on milk production. In animal studies, adapalene is 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 adapalene 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 mother's clinical need for DIFFERIN Gel and any potential adverse effects on the breastfed child from DIFFERIN Gel, or from the underlying maternal condition. Clinical Considerations To minimize potential exposure to the breastfed infant via breastmilk, use DIFFERIN Gel on the smallest area of skin and for the shortest duration possible while breastfeeding. Avoid application of DIFFERIN Gel to areas with increased risk for potential ingestion by or ocular exposure to the breastfeeding child.
Pediatric use
Information about any limitations on any pediatric indications, needs for specific monitoring, hazards associated with use of the drug in any subsets of the pediatric population (such as neonates, infants, children, or adolescents), differences between pediatric and adult responses to the drug, and other information related to the safe and effective pediatric use of the drug.8.4 Pediatric Use Safety and effectiveness have not been established in pediatric patients below the age of 12.
Pregnancy
Information about effects the drug may have on pregnant women or on a fetus. This field may be ommitted if the drug is not absorbed systemically and the drug is not known to have a potential for indirect harm to the fetus. It may contain information about the established pregnancy category classification for the drug. (That information is nominally listed in the teratogenic_effects field, but may be listed here instead.)8.1 Pregnancy Risk Summary Available data from clinical trials with DIFFERIN Gel use in pregnant women are insufficient to establish a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. In animal reproduction studies, oral administration of adapalene to pregnant rats and rabbits during organogenesis at dose exposures 40 and 81 times, respectively, the human exposure at the maximum recommended human dose (MRHD) of 2 g resulted in fetal skeletal and visceral 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 defects, 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 are 2 to 4% and 15 to 20%, respectively. Data Animal Data No malformations were observed in rats treated with oral adapalene doses of 0.15 to 5.0 mg/kg/day, up to 8 times the MRHD based on a mg/m² comparison. However, malformations were observed in rats and rabbits when treated with oral doses of ≥ 25 mg/kg/day adapalene (40 and 81 times the MRHD, respectively, based on a mg/m² comparison). Findings included cleft palate, microphthalmia, encephalocele, and skeletal abnormalities in rats and umbilical hernia, exophthalmos, and kidney and skeletal abnormalities in rabbits. Dermal adapalene embryofetal development studies in rats and rabbits at doses up to 6.0 mg/kg/day (9.7 and 19.5 times the MRHD, respectively, based on a mg/m 2 comparison) exhibited no fetotoxicity and only minimal increases in skeletal variations (supernumerary ribs in both species and delayed ossification in rabbits).
Use in specific populations
Information about use of the drug by patients in specific populations, including pregnant women and nursing mothers, pediatric patients, and geriatric patients.8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary Available data from clinical trials with DIFFERIN Gel use in pregnant women are insufficient to establish a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. In animal reproduction studies, oral administration of adapalene to pregnant rats and rabbits during organogenesis at dose exposures 40 and 81 times, respectively, the human exposure at the maximum recommended human dose (MRHD) of 2 g resulted in fetal skeletal and visceral 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 defects, 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 are 2 to 4% and 15 to 20%, respectively. Data Animal Data No malformations were observed in rats treated with oral adapalene doses of 0.15 to 5.0 mg/kg/day, up to 8 times the MRHD based on a mg/m² comparison. However, malformations were observed in rats and rabbits when treated with oral doses of ≥ 25 mg/kg/day adapalene (40 and 81 times the MRHD, respectively, based on a mg/m² comparison). Findings included cleft palate, microphthalmia, encephalocele, and skeletal abnormalities in rats and umbilical hernia, exophthalmos, and kidney and skeletal abnormalities in rabbits. Dermal adapalene embryofetal development studies in rats and rabbits at doses up to 6.0 mg/kg/day (9.7 and 19.5 times the MRHD, respectively, based on a mg/m 2 comparison) exhibited no fetotoxicity and only minimal increases in skeletal variations (supernumerary ribs in both species and delayed ossification in rabbits). 8.2 Lactation Risk Summary There are no data on the presence of topical adapalene gel or its metabolite in human milk, the effects on the breastfed infant, or the effects on milk production. In animal studies, adapalene is 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 adapalene 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 mother's clinical need for DIFFERIN Gel and any potential adverse effects on the breastfed child from DIFFERIN Gel, or from the underlying maternal condition. Clinical Considerations To minimize potential exposure to the breastfed infant via breastmilk, use DIFFERIN Gel on the smallest area of skin and for the shortest duration possible while breastfeeding. Avoid application of DIFFERIN Gel to areas with increased risk for potential ingestion by or ocular exposure to the breastfeeding child. 8.4 Pediatric Use Safety and effectiveness have not been established in pediatric patients below the age of 12. 8.5 Geriatric Use Clinical studies of DIFFERIN Gel did not include subjects 65 years of age and older to determine whether they respond differently than younger subjects. Safety and effectiveness in geriatric patients age 65 and above have not been established.
