Outcome Measures

Primary Outcome Measures

  1. Change From Baseline in Inflammatory Lesion Counts to Week 16 (Last Observation Carried Forward [LOCF]) [From Baseline up to Week 16 (LOCF)]

    The Inflammatory lesion count was the count of papules and pustules: papule was a small, solid elevation less than 0.5 cm in diameter, pustule was a small, circumscribed elevation of the skin that contains yellow-white exudate. Change from baseline in inflammatory lesion counts to Week 16 (LOCF) were reported.

Secondary Outcome Measures

  1. Investigator Global Assessment (IGA) Success Rate at Week 16 (Last Observation Carried Forward [LOCF]) [Week 16 (LOCF)]

    IGA scale consisted of 5 grades (0-4) among which 0= Clear (no evidence of papules or pustules [inflammatory lesions]), 1= Almost clear (rare non-inflamed papules (papules must be resolving and hyperpigmented, though not pink-red), 2= Mild (few inflammatory lesions [papules/pustules only; no nodulo-cystic lesions]), 3=Moderate (multiple inflammatory lesions evident: many papules/pustules; up to two nodulocystic lesions), 4= Severe (inflammatory lesions are more apparent, many papules/pustules, few nodulo-cystic lesions). Success rate was defined as percentage of participants who achieved an Investigator Global Assessment (IGA) score of 1 (almost clear) or 0 (Clear) and at least a 2-grade improvement from Baseline to Week 16 (LOCF).

  2. Percent Change From Baseline in Inflammatory Lesion Counts to Week 16 (Last Observation Carried Forward [LOCF]) [From Baseline up to Week 16 (LOCF)]

    The Inflammatory lesion count was the count of papules and pustules: papule was a small, solid elevation less than 0.5 cm in diameter, pustule was a small, circumscribed elevation of the skin that contains yellow-white exudate. Percent change from baseline in inflammatory lesion counts to Week 16 (LOCF) were reported.

  3. Percent Change From Baseline in Total Lesion Counts to Week 16 (Last Observation Carried Forward [LOCF]) [From Baseline up to Week 16 (LOCF)]

    Total lesions were the sum of inflammatory lesion counts, non-inflammatory lesion counts, nodules and cysts. Percentage change from baseline in total lesion counts to Week 16 were reported.

  4. Change From Baseline in Non-Inflammatory Lesion Counts to Week 16 (Last Observation Carried Forward [LOCF]) [From Baseline up to Week 16 (LOCF)]

    The non-inflammatory lesion count was the count of open and closed comedones: Open comedone was a pigmented dilated pilosebaceous orifice (blackhead). Closed comedone was a tiny white papule (whitehead). Change from baseline in non-inflammatory lesion counts to week 16 were reported

  5. Global Assessment for Inflammatory Lesions of Truncal Acne at Baseline, Week 12, and Week 16 [Baseline, Week 12, and Week 16]

    Global assessments for inflammatory lesions of truncal acne were done separately on back and chest. The global assessments severity scale included 5 grades (0-4): where in 0= Clear-no evidence of papules or pustules (inflammatory lesions), 1= Almost clear- rare non-inflamed papules (papules must be resolving and may be hyperpigmented, though not pink-red), 2=Mild- few inflammatory lesions (papules/pustules only; no nodulo-cystic lesions), 3=Moderate- multiple inflammatory lesions evident: many papules/pustules; may be a few nodulocystic lesions, 4=Severe- inflammatory lesions are more apparent, many papules/pustules, may be a few nodulo-cystic lesions.

  6. Number of Participants With at Least One Adverse Event (AE) [From Baseline up to Week 16]

    An AE was any untoward medical occurrence in a participant or clinical investigation participants administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. Number of participants with at least one AE were reported.
