CABTREO

CABTREO (clindamycin phosphate, adapalene, and benzoyl peroxide) topical gel is a white to off-white, opaque gel. Each gram of CABTREO contains 12 mg (1.2%) clindamycin phosphate, equivalent to 10 mg (1%) clindamycin and 1.5 mg (0.15%) adapalene, and 31 mg (3.1%) benzoyl peroxide. Clindamycin phosphate is a water-soluble ester of the semisynthetic antibiotic produced by a 7(S)-chloro-substitution of the 7(R)-hydroxyl group of the parent antibiotic lincomycin. Adapalene, a synthetic retinoid, is a naphthoic acid derivative with retinoid-like properties. Benzoyl peroxide is an oxidizing agent. The chemical name for clindamycin phosphate is Methyl-7-chloro-6,7,8-trideoxy-6-(1-methyl-trans-4-propyl-L-2-pyrrolidinecarboxamido)-1-thio-L-threo-α-D-galacto-octopyranoside 2-(dihydrogen phosphate). The structural formula for clindamycin phosphate is represented below: Clindamycin phosphate: Molecular Formula: C 18 H 34 ClN 2 O 8 PS Molecular Weight: 504.97 The chemical name for adapalene is 6-[3-(1-Adamantyl)-4-methoxyphenyl]-2-naphthoic acid. The structural formula for adapalene is represented below: Adapalene: Molecular Formula: C 28 H 28 O 3 Molecular Weight: 412.52 The chemical name for benzoyl peroxide is dibenzoyl peroxide. The structural formula for benzoyl peroxide is represented below: Benzoyl peroxide: Molecular Formula: C 14 H 10 O 4 Molecular Weight: 242.23 CABTREO contains the following inactive ingredients: carbomer homopolymer type C (carbomer 980), potassium hydroxide, propylene glycol, and purified water. image1 image2 image3

CABTREO is indicated for the topical treatment of acne vulgaris in adult and pediatric patients 12 years of age and older. CABTREO is a combination of clindamycin phosphate (a lincosamide antibacterial), adapalene (a retinoid), and benzoyl peroxide indicated for the topical treatment of acne vulgaris in adult and pediatric patients 12 years of age and older.

Cleanse the affected area gently. After the skin is dry, apply a thin layer of CABTREO to the affected area once daily. Wash hands thoroughly after application of CABTREO. Avoid the eyes, mouth, paranasal creases, mucous membranes, and areas of broken, eczematous, or sunburned skin [ see Warnings and Precautions ( 5.3 )]. CABTREO is for topical use only. Not for oral, ophthalmic, or intravaginal use. Apply a thin layer of CABTREO to the affected areas once daily.

CABTREO is contraindicated in patients with: Known hypersensitivity to clindamycin, adapalene, benzoyl peroxide, any other components of CABTREO, or lincomycin [ see Warnings and Precautions ( 5.1 )]. A history of regional enteritis, ulcerative colitis, or antibiotic-associated colitis [ see Warnings and Precautions ( 5.2 )]. Known hypersensitivity to clindamycin, adapalene, benzoyl peroxide, any components of the formulation, or lincomycin. ( 4 ) History of regional enteritis, ulcerative colitis, or antibiotic-associated colitis. ( 4 )

The following adverse reactions are discussed in more detail in other sections of the labeling: Hypersensitivity [ see Warnings and Precautions ( 5.1 )] Colitis [see Warnings and Precautions ( 5.2 )] Skin Irritation and Allergic Contact Dermatitis [see Warnings and Precautions ( 5.4 )] The most common adverse reactions (occurring in >1% of the CABTREO group and greater than the vehicle group) were application site reactions, pain, erythema, dryness, irritation, exfoliation, and dermatitis.

In two multicenter, randomized, double-blind, vehicle-controlled clinical trials (Trial 1 and Trial 2), 363 adult and pediatric subjects 10 years of age and older with facial acne vulgaris were treated with CABTREO or vehicle topically once daily for 12 weeks [see Clinical Studies ( 14 )] . Adverse reactions reported by >1% of subjects treated with CABTREO and more frequently than subjects treated with vehicle are summarized in Table 1. These adverse reactions were mild (59%), moderate (36.4%), and severe (4.5%). Overall, 2.5% (6/242) of subjects discontinued CABTREO because of local skin reactions. Table 1: Adverse Reactions Reported by >1% of Subjects with Facial Acne Vulgaris Treated with CABTREO (and More Frequently than Vehicle) in Trials 1 and 2 Adverse Reactions N (%) CABTREO N=242 Vehicle N=121 Application site pain Application site pain also includes application site stinging and burning 33 (13.6) 1 (0.8) Application site erythema Application site erythema also includes erythema 11 (4.5) 0 Application site dryness Application site dryness also includes xerosis 10 (4.1) 1 (0.8) Application site irritation 5 (2.1) 0 Application site exfoliation 4 (1.7) 0 Application site dermatitis 3 (1.2) 0 Local tolerability evaluations were conducted at each study visit by assessment of erythema, scaling, itching, burning, and stinging. Table 2 presents the signs and symptoms of local facial tolerability during the 12 Week treatment period in subjects treated with CABTREO. Table 2: Facial Cutaneous Tolerability Assessment During 12-Week Treatment Period in Subjects with Acne Vulgaris Treated with CABTREO in Trials 1 and 2 Maximum During Treatment The denominators for calculating the percentages were the number of subjects with at least one post-baseline cutaneous tolerability assessment. Week 12 (End of Treatment) The denominators for calculating the percentages were the number of subjects with Week 12 assessment.

Because post-marketing adverse 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. Immune system disorders: anaphylaxis and allergic reactions including eyelid edema, throat tightness, swelling of the face, and eczema. [see Contraindications ( 4 )] . Local Adverse Reactions: sunburn, blister, pruritis, hyperpigmentation and hypopigmentation. Gastrointestinal Disorders: abdominal pain and gastrointestinal disturbances. Bacterial infections: gram negative folliculitis

Neuromuscular Blocking Agents Clindamycin has been shown to have neuromuscular blocking properties that may enhance the action of other neuromuscular blocking agents. Use CABTREO with caution in patients receiving such agents. Neuromuscular Blocking Agents: Use CABTREO with caution in patients receiving neuromuscular blocking agents. ( 7 )
