( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Allergan at 1-800-678-1605 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 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 clinical practice. In human dermal safety trials, TAZORAC Cream, 0.05% and 0.1% did not induce allergic contact sensitization, phototoxicity, or photoallergy. Psoriasis The most frequent adverse reactions reported with TAZORAC Cream, 0.05% and 0.1% occurring in 10 to 23% of subjects, in descending order, included pruritus, erythema, and burning. Reactions occurring in greater than 1 to less than 10% of subjects, in descending order, included irritation, desquamation, stinging, contact dermatitis, dermatitis, eczema, worsening of psoriasis, skin pain, rash, hypertriglyceridemia, dry skin, skin inflammation, and peripheral edema. TAZORAC Cream, 0.1% was associated with a greater degree of local irritation than the 0.05% cream. The rates of irritation adverse reactions reported during psoriasis trials with TAZORAC Cream, 0.1% were 0.1-0.4% higher than those reported for TAZORAC Cream, 0.05%. Acne The most frequent adverse reactions reported during clinical trials with TAZORAC Cream 0.1% in the treatment of acne, occurring in 10-30% of subjects, in descending order included desquamation, dry skin, erythema, and burning sensation. Reactions occurring in 1 to 5% of subjects included pruritus, irritation, face pain, and stinging. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of tazarotene. Because 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. Skin and subcutaneous tissue disorders : blister, dermatitis, urticaria, skin exfoliation, skin discoloration (including skin hyperpigmentation or skin hypopigmentation), swelling at or near application sites, and pain.

4 CONTRAINDICATIONS TAZORAC Cream is contraindicated in: Pregnancy. Retinoids may cause fetal harm when administered to a pregnant female [see Warnings and Precautions ( 5.1 ), Use in Specific Populations ( 8.1 , 8.3 )] . Individuals who have known hypersensitivity to any of its components [see Warnings and Precautions ( 5.2 )] . Pregnancy ( 4 , 8.1 ) Hypersensitivity ( 4 )

11 DESCRIPTION TAZORAC (tazarotene) Cream, 0.05% and 0.1% is for topical use and contains the active ingredient, tazarotene. Each gram of TAZORAC Cream, 0.05% and 0.1% contains 0.5 and 1 mg of tazarotene, respectively in a white cream base. Tazarotene is a member of the acetylenic class of retinoids. Chemically, tazarotene is ethyl 6-[(4,4-dimethylthiochroman-6-yl) ethynyl]nicotinate. The compound has an empirical formula of C 21 H 21 NO 2 S and molecular weight of 351.46. The structural formula is shown below: TAZORAC Cream contains the following inactive ingredients: benzyl alcohol 1%; carbomer 1342; carbomer homopolymer type B; edetate disodium; medium chain triglycerides; mineral oil; purified water; sodium hydroxide; sodium thiosulfate; and sorbitan monooleate. CHEMICAL-STRUCTURE

2 DOSAGE AND ADMINISTRATION Apply a thin layer of TAZORAC Cream only to the affected area once daily in the evening. ( 2.1 , 2.2 ) Not for ophthalmic, oral, or intravaginal use. ( 2.2 ) If contact with eyes occurs, rinse thoroughly with water. ( 2.2 ) 2.1 Important Administration Instructions TAZORAC Cream is for topical use only. TAZORAC Cream is not for ophthalmic, oral, or intravaginal use. If contact with mucous membranes occurs, rinse thoroughly with water [see Warnings and Precaution ( 5.2 )] . Wash hands thoroughly after application. 2.2 Psoriasis It is recommended that treatment starts with TAZORAC Cream, 0.05%, with strength increased to 0.1% if tolerated and medically indicated. Apply a thin film (2 mg/cm 2 ) of TAZORAC Cream once per day, in the evening, to cover only the psoriatic lesions. If a bath or shower is taken prior to application, the skin should be dry before applying the cream. If emollients are used, they should be applied at least an hour before application of TAZORAC Cream. Because unaffected skin may be more susceptible to irritation, application of TAZORAC Cream to these areas should be carefully avoided. 2.3 Acne Cleanse the face gently. After the skin is dry, apply a thin layer (2 mg/cm 2 ) of TAZORAC Cream 0.1% once per day, in the evening, to the skin areas where acne lesions appear. Use enough to cover the entire affected area. Use effective sunscreens and wear protective clothing while using TAZORAC Cream [see Warnings and Precaution ( 5.3 )] .

1 INDICATIONS AND USAGE TAZORAC ® Cream 0.05% and 0.1% is a retinoid indicated for the topical treatment of plaque psoriasis. ( 1.1 ) TAZORAC Cream 0.1% is indicated for the topical treatment of acne vulgaris. ( 1.2 ) 1.1 Plaque Psoriasis TAZORAC ® (tazarotene) Cream, 0.05% and 0.1% are indicated for the topical treatment of patients with plaque psoriasis. 1.2 Acne Vulgaris TAZORAC (tazarotene) Cream, 0.1% is also indicated for the topical treatment of patients with acne vulgaris.

10 OVERDOSAGE Excessive topical use of TAZORAC Cream, 0.05% and 0.1% may lead to marked redness, peeling, or discomfort [see Warnings and Precautions ( 5.2 )] . TAZORAC Cream, 0.05% and 0.1% are not for oral use. Oral ingestion of the drug may lead to the same adverse effects as those associated with excessive oral intake of Vitamin A (hypervitaminosis A) or other retinoids. If oral ingestion occurs, the patient should be monitored, and appropriate supportive measures should be administered as necessary.

7 DRUG INTERACTIONS No formal drug-drug interaction studies were conducted with TAZORAC Cream. In a trial of 27 healthy female subjects between the ages of 20–55 years receiving a combination oral contraceptive tablet containing 1 mg norethindrone and 35 mcg ethinyl estradiol, concomitant use of tazarotene administered as 1.1 mg orally (mean ± SD C max and AUC 0-24 of tazarotenic acid were 28.9 ± 9.4 ng/mL and 120.6 ± 28.5 ng • hr/mL) did not affect the pharmacokinetics of norethindrone and ethinyl estradiol over a complete cycle. The impact of tazarotene on the pharmacokinetics of progestin only oral contraceptives (i.e., minipills) has not been evaluated.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Tazarotene is a retinoid prodrug which is converted to its active form, the carboxylic acid of tazarotene, by deesterification. Tazarotenic acid binds to all three members of the retinoic acid receptor (RAR) family: RARα, RARβ, and RARɣ, but shows relative selectivity for RARβ, and RARɣ and may modify gene expression. The clinical significance of these findings is unknown. 12.3 Pharmacokinetics Following topical application, tazarotene undergoes esterase hydrolysis to form its active metabolite, tazarotenic acid. Little parent compound could be detected in the plasma. Tazarotenic acid was highly bound to plasma proteins (greater than 99%). Tazarotene and tazarotenic acid were metabolized to sulfoxides, sulfones and other polar metabolites which were eliminated through urinary and fecal pathways. The half-life of tazarotenic acid was approximately 18 hours, following topical application of tazarotene to normal, acne or psoriatic skin. In a multiple dose trial with a once daily dose for 14 consecutive days in 9 psoriatic subjects (male=5; female=4), measured doses of TAZORAC Cream, 0.1% were applied by medical staff to involved skin without occlusion (5 to 35% of total body surface area: mean ± SD: 14 ± 11%). The C max of tazarotenic acid was 2.31 ± 2.78 ng/mL occurring 8 hours after the final dose, and the AUC 0-24h was 31.2 ± 35.2 ng·hr/mL on day 15 in the five subjects who were administered clinical doses of 2 mg cream/cm 2 . During clinical trials with TAZORAC Cream, 0.05% or 0.1% treatment for plaque psoriasis, three out of 139 subjects with their systemic exposure monitored had detectable plasma tazarotene concentrations, with the highest value at 0.09 ng/mL. Tazarotenic acid was detected in 78 out of 139 subjects (LLOQ = 0.05 ng/mL). Three subjects using tazarotene cream 0.1% had plasma tazarotenic acid concentrations greater than 1 ng/mL. The highest value was 2.4 ng/mL. However, because of the variations in the time of blood sampling, the area of psoriasis involvement, and the dose of tazarotene applied, actual maximal plasma levels are unknown. TAZORAC Cream 0.1% was applied once daily to either the face (N=8) or to 15% of body surface area (N=10) of female subjects with moderate to severe acne vulgaris. The mean C max and AUC values of tazarotenic acid peaked at day 15 for both dosing groups during a 29 day treatment period. Mean C max and AUC 0-24h values of tazarotenic acid from subjects in the 15% body surface area dosing group were more than 10 times higher than those from subjects in the face-only dosing group. The single highest C max throughout the trial period was 1.91 ng/mL on day 15 in the exaggerated dosing group. In the face-only group, the mean ± SD values of C max and AUC 0-24h of tazarotenic acid on day 15 were 0.10 ± 0.06 ng/mL and 1.54 ± 1.01 ng·hr/mL, respectively, whereas in the 15% body surface area dosing group, the mean ± SD values of C max and AUC 0-24h of tazarotenic acid on day 15 were 1.20 ± 0.41 ng/mL and 17.01 ± 6.15 ng·hr/mL, respectively. The steady state pharmacokinetics of tazarotenic acid had been reached by day 8 in the face-only and by day 15 in the 15% body surface area dosing groups. In a Phase 3 clinical trial, TAZORAC Cream, 0.1% was applied once daily for 12 weeks to each of 48 subjects (22 females and 26 males) with facial acne vulgaris. The mean ± SD values of plasma tazarotenic acid at weeks 4 and 8 were 0.078 ± 0.073 ng/mL (N=47) and 0.052 ± 0.037 ng/mL (N=42), respectively. The highest observed individual plasma tazarotenic acid concentration was 0.41 ng/mL at week 4 from a female subject. The magnitude of plasma tazarotenic acid concentrations appears to be independent of gender, age, and body weight.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis A long-term study of tazarotene following oral administration of 0.025, 0.050, and 0.125 mg/kg/day to rats showed no indications of increased carcinogenic risks. Based on pharmacokinetic data from a shorter term study in rats, the highest dose of 0.125 mg/kg/day was anticipated to give systemic exposure in the rat equivalent to 0.6 times that seen in a psoriatic patient treated with 0.1% tazarotene cream at 2 mg/kg/cm 2 over a 35% body surface area in a controlled pharmacokinetic study. This estimated systemic exposure in rats was 2 times the maximum systemic exposure in acne patients treated with tazarotene cream, 0.1% cream at 2 mg/cm 2 over a 15% body surface area. A long-term topical application study of up to 0.1% of tazarotene in a gel formulation in mice terminated at 88 weeks showed that dose levels of 0.05, 0.125, 0.25, and 1 mg/kg/day (reduced to 0.5 mg/kg/day for males after 41 weeks due to severe dermal irritation) revealed no apparent carcinogenic effects when compared to vehicle control animals. Systemic exposures at the highest dose was 3.9 times that seen in a psoriatic patient treated with 0.1% tazarotene cream at 2 mg/cm 2 over a 35% body surface area in a controlled pharmacokinetic study, and 13 times the maximum systemic exposure in acne patients treated with tazarotene cream, 0.1% at 2 mg/cm 2 over a 15% body surface area. In evaluation of photo co-carcinogenicity, median time to onset of tumors was decreased, and the number of tumors increased in hairless mice following chronic topical dosing with intercurrent exposure to ultraviolet radiation at tazarotene concentrations of 0.001%, 0.005%, and 0.01% in a gel formulation for up to 40 weeks. Mutagenesis Tazarotene was found to be non-mutagenic in the Ames assay and did not produce structural chromosomal aberrations in a human lymphocyte assay. Tazarotene was non-mutagenic in the CHO/HGPRT mammalian cell forward gene mutation assay and was non-clastogenic in the in vivo mouse micronucleus test. Impairment of Fertility No impairment of fertility occurred in rats when male animals were treated for 70 days prior to mating and female animals were treated for 14 days prior to mating and continuing through gestation and lactation with topical doses of tazarotene gel up to 0.125 mg/kg/day. Based on data from another study, the systemic drug exposure in the rat would be equivalent to 0.6 times that observed in a psoriatic patient treated with 0.1% tazarotene cream at 2 mg/cm 2 over a 35% body surface area in a controlled pharmacokinetic study, and 2 times the maximum systemic exposure in acne patients treated with tazarotene cream, 0.1% at 2 mg/cm 2 over a 15% body surface area. No impairment of mating performance or fertility was observed in male rats treated for 70 days prior to mating with oral doses of up to 1 mg/kg/day tazarotene. That dose produced a systemic exposure that was 1.9 times that observed in a psoriatic patient treated with 0.1% tazarotene cream at 2 mg/cm 2 over a 35% body surface area, and 6.3 times the maximum systemic exposure in acne patients treated with tazarotene cream, 0.1% at 2 mg/cm 2 over a 15% body surface area. No impairment of mating performance or fertility was observed in female rats treated for 15 days prior to mating and continuing through gestation day 7 with oral doses up to 2 mg/kg/day of tazarotene. However, there was a significant decrease in the number of estrous stages and an increase in developmental effects at that dose [see Use in Specific Populations ( 8.1 )] . That dose produced a systemic exposure that was 3.4 times that observed in a psoriatic patient treated with 0.1% tazarotene cream at 2 mg/cm 2 over a 35% body surface area and 11 times the maximum systemic exposure in acne patients treated with tazarotene cream, 0.1% at 2 mg/cm 2 over a 15% body surface area. Reproductive capabilities of F1 animals, including F2 survival and development, were not affected by topical administration of tazarotene gel to female F0 parental rats from gestation day 16 through lactation day 20 at the maximum tolerated dose of 0.125 mg/kg/day. Based on data from another study, the systemic drug exposure in the rat would be equivalent to 0.6 times that observed in a psoriatic patient treated with 0.1% tazarotene cream at 2 mg/cm 2 over a 35% body surface area, and 2 times the maximum systemic exposure in acne patients treated with tazarotene cream, 0.1% at 2 mg/cm 2 over a 15% body surface area.

14 CLINICAL STUDIES In two 12-week vehicle-controlled clinical trials, TAZORAC Cream, 0.05% and 0.1% was significantly more effective than vehicle in reducing the severity of stable plaque psoriasis. TAZORAC Cream, 0.1% and 0.05% demonstrated superiority over vehicle cream as early as 1 week and 2 weeks, respectively, after starting treatment. In these trials, the primary efficacy endpoint was “clinical success,” defined as the proportion of subjects with none, minimal, or mild overall lesional assessment at Week 12, and shown in Table 1 . “Clinical success” was also significantly greater with TAZORAC Cream, 0.05% and 0.1% versus vehicle at most follow-up visits.

8.5 Geriatric Use TAZORAC Cream for the treatment of acne has not been clinically tested in persons 65 years of age or older. Of the total number of subjects in clinical trials of TAZORAC Cream for plaque psoriasis, 120 were over the age of 65. No overall differences in safety or effectiveness were observed between these subjects and younger subjects. Currently there is no other clinical experience on the differences in responses between the elderly and younger subjects, but greater sensitivity of some older individuals cannot be ruled out.

8.4 Pediatric Use The safety and efficacy of TAZORAC Cream have not been established in patients with psoriasis under the age of 18 years, or in patients with acne under the age of 12 years.

8.1 Pregnancy Risk Summary Based on data from animal reproduction studies, retinoid pharmacology, and the potential for systemic absorption, TAZORAC Cream may cause fetal harm when administered to a pregnant female and is contraindicated during pregnancy. Safety in pregnant females has not been established. The potential risk to the fetus outweighs the potential benefit to the mother from TAZORAC Cream during pregnancy; therefore, TAZORAC Cream should be discontinued as soon as pregnancy is recognized [see Contraindications ( 4 ), Warnings and Precautions ( 5.1 ), Clinical Pharmacology ( 12.3 )]. Limited case reports of pregnancy in females enrolled in clinical trials for TAZORAC Cream have not established a clear association with tazarotene and major birth defects or miscarriage risk. Because the exact timing and extent of exposure in relation to the gestational age are not certain, the significance of these findings is unknown. In animal reproduction studies with pregnant rats, tazarotene dosed topically during organogenesis at 2 times the maximum systemic exposure in subjects treated with the maximum recommended human dose (MRHD) of tazarotene cream, 0.1% resulted in reduced fetal body weights and reduced skeletal ossification. In animal reproduction studies with pregnant rabbits dosed topically with tazarotene gel at 26 times the maximum systemic exposure in subjects treated with the MRHD of tazarotene cream, 0.1%, there was a single incident of known retinoid malformations, including spina bifida, hydrocephaly, and heart anomalies. In animal reproduction studies with pregnant rats and rabbits, tazarotene dosed orally during organogenesis at 2 and 52 times, respectively, the maximum systemic exposure in subjects treated with the MRHD of tazarotene cream, 0.1% resulted in malformations, fetal toxicity, developmental delays, and/or behavioral delays. In pregnant rats, tazarotene dosed orally prior to mating through early gestation resulted in decreased litter size, decreased numbers of live fetuses, decreased fetal body weights, and increased malformations at doses approximately 7 times higher than the maximum systemic exposure in subjects treated with the MRHD of tazarotene cream, 0.1% [see Data ]. The background risk of major birth defects and miscarriage for the indicated population is unknown. Adverse outcomes in pregnancy occur regardless of the health of the mother or the use of medications. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data In rats, a tazarotene gel, 0.05% formulation dosed topically during gestation days 6 through 17 at 0.25 mg/kg/day, which represented 2 times the maximum systemic exposure in subjects treated with the MRHD of tazarotene cream, 0.1% ( i.e. , 2 mg/cm 2 over a 15% body surface area), resulted in reduced fetal body weights and reduced skeletal ossification. Rabbits dosed topically with 0.25 mg/kg/day tazarotene gel, which represented 26 times the maximum systemic exposure in subjects treated with MRHD of tazarotene cream, 0.1%, during gestation days 6 through 18, had a single incident of known retinoid malformations, including spina bifida, hydrocephaly, and heart anomalies. When tazarotene was given orally to animals, developmental delays were seen in rats, and malformations and post-implantation loss were observed in rats and rabbits at doses representing 2 and 52 times, respectively, the maximum systemic exposure seen in subjects treated with the MRHD of tazarotene cream, 0.1%. In female rats orally administered 2 mg/kg/day of tazarotene from 15 days before mating through gestation day 7, which represented 7 times the maximum systemic exposure in subjects treated with the MRHD of tazarotene cream, 0.1%, classic developmental effects of retinoids were observed including decreased number of implantation sites, decreased litter size, decreased numbers of live fetuses, and decreased fetal body weights. A low incidence of retinoid-related malformations was observed at that dose. In a pre- and postnatal development toxicity study, topical administration of tazarotene gel (0.125 mg/kg/day) to pregnant female rats from gestation day 16 through lactation day 20 reduced pup survival, but did not affect the reproductive capacity of the offspring. Based on data from another study, the maximum systemic exposure in the rat would be equivalent to the maximum systemic exposure in subjects treated with the MRHD of tazarotene cream, 0.1%.

Based on data from another study, the maximum systemic exposure in the rat would be equivalent to the maximum systemic exposure in subjects treated with the MRHD of tazarotene cream, 0.1%. 8.2 Lactation Risk Summary There is no information regarding the presence of tazarotene in human milk, the effects on the breastfed infant, or the effects on milk production. After single topical doses of 14 C-tazarotene gel to the skin of lactating rats, radioactivity was detected in rat milk. The lack of clinical data during lactation precludes a clear determination of the risk of TAZORAC Cream to an infant during lactation; therefore, the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TAZORAC Cream and any potential adverse effects on the breastfed child from TAZORAC Cream or from the underlying maternal condition. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Pregnancy testing is recommended for females of reproductive potential within 2 weeks prior to initiating TAZORAC Cream therapy which should begin during a menstrual period. Contraception Females Based on animal studies, TAZORAC Cream may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations ( 8.1 )]. Advise females of reproductive potential to use effective contraception during treatment with TAZORAC Cream. 8.4 Pediatric Use The safety and efficacy of TAZORAC Cream have not been established in patients with psoriasis under the age of 18 years, or in patients with acne under the age of 12 years. 8.5 Geriatric Use TAZORAC Cream for the treatment of acne has not been clinically tested in persons 65 years of age or older. Of the total number of subjects in clinical trials of TAZORAC Cream for plaque psoriasis, 120 were over the age of 65.
