Study STF115287, a Clinical Confirmation Study of GSK2585823 in the Treatment of Acne Vulgaris in Japanese Subjects
This is a multicenter, randomized, single-blinded (investigator's blinded), active-controlled
 (clindamycin [CLDM] 1% gel), parallel-group study in Japanese subjects with acne vulgaris to
 demonstrate the efficacy of GSK2585823 (CLDM 1%-benzoyl peroxide [BPO] 3% gel) when applied
 once or twice daily for 12 weeks. This study will also evaluate the safety of GSK2585823 when
 applied topically either once or twice daily for 12 weeks.
Main inclusion criteria will be 12 to 45 years of age, who have an Investigator Static Global
 Assessment (ISGA) score of 2 or greater at baseline visit, and have both 17 to 60 facial
 inflammatory lesions (papules plus pustules) and 20 to 150 facial non-inflammatory lesions
 (open and closed comedones), including nasal lesions. The primary objectives are to
 demonstrate the superiority of GSK2585823 twice daily to CLDM twice daily in total lesion
 counts, and to demonstrate the non-inferiority of GSK2585823 once daily to CLDM twice daily
 in total lesion counts. The secondary objectives are to demonstrate the non-inferiority of
 GSK2585823 once daily to CLDM twice daily in inflammatory lesion counts, and to evaluate the
 efficacy of GSK2585823 once or twice daily compared with CLDM twice daily at each visit. A
 total of 800 subjects will be enrolled and randomly assigned to one of the groups.
Inclusion Criteria:

 -  Male or female subjects 12 to 45 years (inclusive) of age in good general health.

 -  Subjects must have both on the face:

 A) A minimum of 17 but not more than 60 inflammatory lesions (papules/pustules), including
 nasal lesions.

 And B) A minimum of 20 but not more than 150 non-inflammatory lesions (open/closed
 comedones), including nasal lesions.

 -  An ISGA score of 2 or greater at baseline.

 -  Females of childbearing potential and women who are less than 2 years from their last
 menses must agree to use the contraception.

 -  The ability and willingness to follow all study procedures and attend all scheduled
 visits.

 -  The ability to understand and sign a written informed consent form (Written informed
 consent must be obtained also from the parent or guardian in case of subject under 20
 years of age at the time of given consent).

 Exclusion Criteria:

 -  Have any nodule-cystic lesions at baseline.

 -  Are pregnant or breast-feeding.

 -  Have a history or presence of regional enteritis, inflammatory bowel disease (e.g.,
 ulcerative colitis, pseudomembranous colitis, chronic diarrhea or
 antibiotic-associated colitis) or similar symptoms.

 -  Used any of the following agents on the face within the previous 2 weeks:Topical
 antibiotics (or systemic antibiotics);Topical anti-acne medications (e.g., BPO,
 azelaic acid, resorcinol, salicylates);Abradants, facials, or peels containing
 glycolic or other acids;Masks, washes or soaps containing BPO, sulfacetamide sodium,
 or salicylic acid;Non-mild facial cleansers (e.g., facial scrub, cleansers containing
 agents with anti-inflammatory action); Moisturizers that contain retinol, salicylic
 acid, or α- or β-hydroxy acids;Astringents and toner (Subjects are allowed to enroll
 in this study, if the subject has been on treatment for more than 2 consecutive weeks
 prior to start of investigational product use).

 -  Used the following agents on the face or performed the following procedure within the
 previous 4 weeks:Topical corticosteroids (Use of inhaled, intra-articular, or
 intra-lesional steroids other than for facial acne is acceptable);Facial procedure
 (such as chemical or laser peel, microdermabrasion, blue light treatment, etc.).

 -  Used systemic retinoids within the previous 6 months or topical retinoids on the face
 within the previous 6 weeks.

 -  Received treatment with estrogens, androgens, or anti-androgenic agents within the
 previous 12 weeks (Subjects who have been treated with the above agents for more than
 12 consecutive weeks prior to start of investigational product are allowed to enrol as
 long as they do not expect to change dose, drug, or discontinue use during the study).

 -  Used any medication that in the opinion of the investigator may affect this clinical
 study or evaluation of the study.

 -  Plan to use medications that are reported to exacerbate acne (e.g., mega-doses of
 certain vitamins, such as vitamin D [>2000 IU/day] and vitamin B12 [>1 mg/day],
 corticosteroids*, androgens, haloperidol, halogens [e.g., iodide and bromide],
 lithium, hydantoin, and phenobarbital).

 *: except the using of topical corticosteroids (e.g., inhaled, intra-articular, or
 intra-lesional steroids) other than for facial acne.

 -  Have a known hypersensitivity or have had previous allergic reaction to any of the
 components of the investigational product.

 -  Used any investigational therapy within the previous 12 weeks, or plan to participate
 in another clinical study at the same time.

 -  Participated in Japanese clinical studies planned by GlaxoSmithKline K.K. in the
 development of investigational products for acne vulgaris.

 -  Are currently abusing drugs or alcohol.

 -  Have a significant medical history of being immunocompromised.

 -  People as follows and the family members:Employees of GlaxoSmithKline, contract
 research organization (CRO) or site management organization (SMO);Investigators.

 participation in the study.
