Outcome Measures
Primary Outcome Measures
- Absolute Change in Lesion Counts (LCs) From Baseline to Week 12 [Baseline (Week 0/Day 1) and Week 12]
LC: count of all inflammatory lesions (ILs, i.e., papules, pustules, and nodules) and non-inflammatory lesions (NILs, i.e., open and closed comedones) at Baseline and at Week 12. Total lesions (TLs) were calculated as the sum of ILs and NILs. LC was confined to the face (including forehead, nose, checks, and chin). Change from Baseline at Week 12 was calculated as the value at Week 12 minus the value at Baseline.
- Number of Participants With a Minimum 2-grade (G) Improvement in the Investigator Static Global Assessment (ISGA) Score From Baseline at Week 12 [Baseline (Week 0/Day 1) and Week 12]
Investigators evaluated the acne severity (S) of the participants' face using the ISGA scale, ranging from 0 to 5: 0=clear skin with no ILs or NILs; 1=almost clear: rare NIL with no more than rare papules; 2=mild S: >G 1, some NILs with no more than a few ILs (papules/pustules only, no nodular lesions [NLs]); 3=moderate S: >G 2, up to many NILs and may have some ILs, but no more than one small NL; 4=severe: greater than G 3, up to many NILs and ILs, but no more than a few NLs; 5=very severe: many NILs and ILs and more than a few NLs, may have cystic lesions.
- Number of Participants With an ISGA Score of 0 or 1 at Week 12 [Week 12]
Investigators evaluated the acne severity (S) of the participants' face using the ISGA scale, ranging from 0 to 5: 0=clear skin with no ILs or NILs; 1=almost clear: rare NIL with no more than rare papules; 2=mild S: >G 1, some NILs with no more than a few ILs (papules/pustules only, no nodular lesions [NLs]); 3=moderate S: >G 2, up to many NILs and may have some ILs, but no more than one small NL; 4=severe: greater than G 3, up to many NILs and ILs, but no more than a few NLs; 5=very severe: many NILs and ILs and more than a few NLs, may have cystic lesions.
Secondary Outcome Measures
- Percent Change in LC From Baseline at Weeks 2, 4, 8, and 12 [Baseline (Week 0/Day 1); Weeks 2, 4, 8, and 12]
LC: count of all ILs (i.e., papules, pustules, and nodules) and NILs (i.e., open and closed comedones) at Baseline and at Week 12. TLs were calculated as the sum of ILs and NILs. LC was confined to the face (including forehead, nose, checks, and chin). Percent change from Baseline in LC at Weeks 2, 4, 8, and12 was calculated as the (Week 2/4/8/12 value minus the baseline value divided by baseline value) x 100.
- Absolute Change From Baseline in LC at Weeks 2, 4, and 8 [Baseline (Week 0/Day 1); Weeks 2, 4, and 8]
LC: count of all ILs (i.e., papules, pustules, and nodules) and NILs (i.e., open and closed comedones) at Baseline and at Week 12. TLs were calculated as the sum of ILs and NILs. LC was confined to the face (including forehead, nose, checks, and chin). Change from Baseline at Week 12 was calculated as the value at Week 12 minus the value at baseline. Calculation was based on last observation carried forward (LOCF) imputation method for missing data.
- Time to a 50 Percent Reduction in Total Lesion Counts (TLC) [Baseline (Week 0/Day 1) to Week 12]
Time to a 50 percent reduction in TLC (sum of ILs and NILs) was the time difference between Baseline and the time to 50 percent reduction in LC. Participants who did not have a >=50 percent reduction from Baseline in TLC during the study were censored at their last visit date.
- Number of Participants With a Minimum 2-grade Improvement in ISGA Score at Weeks 2, 4, and 8 [Baseline (Week 0/Day 1); Weeks 2, 4, and 8]
Investigators evaluated the acne severity (S) of the participants' face using the ISGA scale, ranging from 0 to 5: 0=clear skin with no ILs or NILs; 1=almost clear: rare NIL with no more than rare papules; 2=mild S: >G 1, some NILs with no more than a few ILs (papules/pustules only, no nodular lesions [NLs]); 3=moderate S: >G 2, up to many NILs and may have some ILs, but no more than one small NL; 4=severe: greater than G 3, up to many NILs and ILs, but no more than a few NLs; 5=very severe: many NILs and ILs and more than a few NLs, may have cystic lesions.
- Number of Participants With an ISGA Score of 0 or 1 at Weeks 2, 4, and 8 [Weeks 2, 4, and 8]
Investigators evaluated the acne severity (S) of the participants' face using the ISGA scale, ranging from 0 to 5: 0=clear skin with no ILs or NILs; 1=almost clear: rare NIL with no more than rare papules; 2=mild S: >G 1, some NILs with no more than a few ILs (papules/pustules only, no nodular lesions [NLs]); 3=moderate S: >G 2, up to many NILs and may have some ILs, but no more than one small NL; 4=severe: greater than G 3, up to many NILs and ILs, but no more than a few NLs; 5=very severe: many NILs and ILs and more than a few NLs, may have cystic lesions.
- Number of Participants With a Subject's Global Assessment (SGA) Score of 0 or 1 at Weeks 2, 4, 8, and 12 [Weeks 2, 4, 8, and 12]
An SGA of the facial skin, excluding the scalp, was performed by participants using a rating scale of 0 to 4: 0=face is basically free of acne, with only an occasional blackhead (Bh) and/or whitehead (Wh); 1=face has several Bhs and/or Whs and small pimples (P), but there are no tender deep-seated bumps or cysts (DSBCs); 2=face has several to many Bhs and/or Whs and small- to medium-sized P, and may have one DSBC; 3=face has many Bhs and/or Whs, many medium- to large-sized P, and perhaps a few DSBCs; 4=face has Bhs and/or Whs, and several to many medium- to large-sized Ps and DSBCs dominate.
- Change in Dermatology Life Quality Index (DLQI) Score From Baseline at Weeks 2, 4, 8, and 12 in Participants 17 Years of Age or Older [Baseline (Week 0/Day 1); Weeks 2, 4, 8, and 12]
The DLQI was used to measure how much the participants' skin problem had affected their life over the last week. The DLQI total score ranges from 0 to 30: 0-1=no effect at all on the participant's life; 2-5=small effect on the participant's life; 6-10=moderate effect on the participant's life; 11-20=very large effect on the participant's life; 21-30=extremely large effect on the participant's life. A lower score on the DLQI indicates increased quality of life; therefore, negative changes from Baseline indicate improvements.
- Change in Children's Dermatology Life Quality Index (CDLQI) From Baseline at Week 2, 4, 8 and 12 in Participant's With 16 Years Old or Younger [Baseline (Week 0/Day 1); Weeks 2, 4, 8, and 12]
The CDLQI was used to measure how much the participants' skin problem had affected their life over the last week. The CDLQI total score ranges from 0 to 30: 0-1=no effect at all on the participant's life; 2-6=small effect on the participant's life; 7-12=moderate effect on the participant's life; 13-18=very large effect on the participant's life; 19-30=extremely large effect on the participant's life. A lower score on the CDLQI indicates increased quality of life; therefore, negative changes from Baseline indicate improvements.
