Primary Outcome Measures:
  • Percent Change in Inflammatory Acne Lesions From Baseline to Week 16 [ Time Frame: Baseline, Week 16 ] [ Designated as safety issue: No ]
    Percent change from baseline to week 16 in inflammatory acne lesions (pustules/papules)(chest and back)

  • Percent (%) Change in Non-inflammatory Acne Lesions From Baseline to Week 16. [ Time Frame: Baseline, Week 16 ] [ Designated as safety issue: No ]
    Percent change in Non-inflammatory acne lesions (whiteheads and blackheads)(chest and back) from baseline to week 16.

  • Percent Change in Total Acne Lesion Counts From Baseline to Week 16 [ Time Frame: Baseline, Week 16 ] [ Designated as safety issue: No ]
    Percent change from baseline to week 16 in total acne lesions (inflammatory + non-inflammatory)

  • Change in Investigator Global Assessment (IGA) [ Time Frame: Baseline, Weeks 4, 8,12, and 16 ] [ Designated as safety issue: No ]

    Change in Investigator Global Assessment (IGA) Average values chest and back.

    IGA scale:

    0 - Clear

    0.5 - Clear/almost clear

    1. Almost Clear

      1.5- Almost Clear/Mild

    2. Mild

      2.5- Mild/Moderate

    3. Moderate

    3.5- Moderate/Severe



Secondary Outcome Measures:
  • Percent (%) Change in Inflammatory Lesion Counts (Chest and Back) From Baseline to Week 12 [ Time Frame: Baseline, Week 12 ] [ Designated as safety issue: No ]
    Percent change in inflammatory lesion counts (chest and back)from Baseline to Week 12

  • Percent Change in Non-inflammatory Lesions (Chest and Back) From Baseline to Week 12 [ Time Frame: Baseline, Week 12 ] [ Designated as safety issue: No ]
    Percent change in non-inflammatory lesions (chest and back) from baseline to Week 12

  • Percent Change in Total Lesions (Chest and Back) From Baseline to Week 12 [ Time Frame: Week 12 ] [ Designated as safety issue: No ]
    Percent change in total lesions (chest and back) from baseline to Week 12

  • Percentage of Particpants With IGA Score at Week 16 [ Time Frame: Baseline, Week 16 ] [ Designated as safety issue: No ]

    Investigator Global Assessment (IGA) at Week 16 based on the Investigator Global Assessment

    IGA:

    0 - Clear

    0.5 - Clear/almost clear

    1. Almost Clear

      1.5- Almost Clear/Mild

    2. Mild

      2.5- Mild/Moderate

    3. Moderate

    3.5- Moderate/Severe
