Outcomes
Primary Outcome Measures
Percent Change in Total Lesion Counts (TLs) From Baseline to Week 2
The assessor performed a count of IL (papules, pustules, nodular lesions), non-ILs (open and closed comedones) and total lesions (the sum of IL and non-IL) at each study visit. Lesion counts were confined to the face. Change from Baseline was calculated as the value at endpoint minus the value at Baseline. Data for adjusted mean has been reported. Percent change from Baseline is the change from Baseline divided by Baseline value multiplied by 100. The Baseline value was the latest pre-dose assessment value. The non-inflammatory lesions were counted by diagnosis based on palpation of the investigator (or sub-investigator).
Secondary Outcome Measures
Percent Change From Baseline in TLs to Weeks 1, 4, 8 and 12
The assessor performed a count of IL (papules, pustules, nodular lesions), non-ILs (open and closed comedones) and total lesions (the sum of IL and non-IL) at each study visit. Lesion counts were confined to the face. Change from Baseline was calculated as the value at endpoint minus the value at Baseline. Data for adjusted mean has been reported. Percent change from Baseline is the change from Baseline divided by Baseline value multiplied by 100. The Baseline value was the latest pre-dose assessment value. The non-ILs were counted by diagnosis based on palpation of the investigator (or sub-investigator). A negative treatment difference indicates a benefit of Duac relative to ADA+CLDM.
Percent Change Form Baseline in Lesion Counts (ILs and Non-ILs) to Weeks 1, 2, 4, 8 and 12
The assessor performed a count of IL (papules, pustules, nodular lesions), non-ILs (open and closed comedones). Lesion counts were confined to the face. Change from Baseline was calculated as the value at endpoint minus the value at Baseline. Data for adjusted mean has been reported. Percent change from Baseline is the change from Baseline divided by Baseline value multiplied by 100. The Baseline value was the latest pre-dose assessment value. The non-ILs were counted by diagnosis based on palpation of the investigator (or sub-investigator).
Absolute Change From Baseline in Lesion Counts (TLs, ILs and Non-ILs) to Weeks 1, 2, 4, 8 and 12
The assessor performed a count of IL (papules, pustules, nodular lesions), non-ILs (open and closed comedones) and total lesions (the sum of IL and non-IL) at each study visit. Lesion counts were confined to the face. Change from Baseline was calculated as the value at endpoint minus the value at Baseline. Data for adjusted mean has been reported. The non-ILs were counted by diagnosis based on palpation of the investigator (or sub-investigator). A negative treatment difference indicates a benefit of Duac relative to ADA+CLDM. The Baseline value was the latest pre-dose assessment value.
Percentage of Participants With a Minimum of 2-grade Improvement in Investigator's Static Global Assessment (ISGA) Score From Baseline to Weeks 1, 2, 4, 8 and 12
Responder was defined as participants with a minimum 2-grade improvement in ISGA score from Baseline. ISGA scale was scored from 0-5 (0= Clear skin with no inflammatory or non-ILs, 1= Almost clear: rare non-ILs present, with no more than rare papules, 2= Mild severity: greater than Grade 1, some non-ILs with no more than few inflammatory lesions, 3= Moderate severity: greater than Grade 2, many non-ILS, may have some ILs, but no more than 1 small nodular lesion, 4= Severe: greater than Grade 3, up to many non-ILs and ILs, but no more than a few nodular lesions, 5= Very severe: many non -ILs and ILs and more than a few nodular lesions. May have cystic lesions). Percentage of participants was calculated by dividing number of participants with 2-grade improvement in ISGA score from Baseline by total number of participants value multiplied by 100.
Percentage of Participants With ISGA Score of 0 or 1 at Weeks 1, 2, 4, 8 and 12
Responder was defined as participant with ISGA score of 0 or 1. ISGA scale was scored from 0-5 (0= Clear skin with no inflammatory or non-ILs, 1= Almost clear: rare non-ILs present, with no more than rare papules, 2= Mild severity: greater than Grade 1, some non-ILs with no more than few inflammatory lesions, 3= Moderate severity: greater than Grade 2, many non-ILS, may have some ILs, but no more than 1 small nodular lesion, 4= Severe: greater than Grade 3, up to many non-ILs and ILs, but no more than a few nodular lesions, 5= Very severe: many non -ILs and ILs and more than a few nodular lesions. May have cystic lesions). Percentage of participants was calculated by dividing number of participants with 0-1 ISGA score post Baseline by total number of participants value multiplied by 100.
Percentage of Participants With at Least 50% Reduction in Lesion Counts (TLs, ILs and Non-ILs) From Baseline at Weeks 1, 2, 4, 8 and 12
Responder was defined as participants with at least a 50% reduction in TLs, ILs and non-ILs. Data for number of participants is reported. Percentage of participants was calculated by dividing number of responders by total number of participants value multiplied by 100.
Number of Participants With Treatment Adherence Rate at Weeks 1, 2, 4, 8 and 12
The investigator (or sub-investigator), the product storage manager, or the blinded coordinator dispensed a study compliance log to record participant's compliance with investigational product application from Baseline to the end of study treatment. The product storage manager or the blinded coordinator evaluated the participant's compliance with study treatment, using the study compliance log at each visit, and recorded the compliance data in the eCRF.
Number of Participants Who Continued Treatment at Weeks 1, 2, 4, 8 and 12
Number of participants who continued the treatment till Week 12 was measured. Overall data for participants who have not missed any dose during the treatment period has been reported.
Participant's Treatment Preference at Weeks 1, 2, 4, 8 and 12
Participants had to rate each question on a 5-point scale of 0 to 4 (4: yes, very easy to use, 3: yes, easy, 2: slightly easy, 1: slightly difficult, 0: No) where larger score indicates more preferable participant's feeling. There were 5 questions in the questionnaire: ease of application, comfort, satisfaction with treatment (ST), comparison with prior therapies (CPT) and willingness to continue using the product (WCP).
Change From Baseline in Quality of Life (QoL) Score at Week 2, 4, 8 and 12
QOL questionnaire was assessed using Skindex-16 with 16 questions in 3 multi-item scales: symptoms, emotions and functioning for the past week: skin condition-itching, burning or stinging, hurting, being irritated, persistence/reoccurrence of skin condition, worry about condition, appearance of skin, frustration about skin, embarrassment about skin, being annoyed about your skin, feeling depressed about skin, effects of your skin on your interactions with others, effects of your skin condition on your desire to be with people, skin condition making it hard to show affection, effects of your skin condition on your daily activities and skin condition making it hard to work or do what you enjoy. Data for adjusted mean has been reported. The Baseline value was the latest pre-dose assessment value. Change from Baseline was calculated as the value at endpoint minus the value at Baseline. Scores range from 0-never bothered to 100-always bothered.
Number of Participants With Any Adverse Events (AEs) and Serious Adverse Events (SAEs)
An AE was defined as any untoward medical occurrence that occurred during the course of the trial after study treatment had started. An adverse event was therefore any unfavorable and unintended sign, symptom, or disease temporally associated with the use of study drug, whether or not considered related to the study drug. A SAE is any untoward medical occurrence that at any dose results in death, are life threatening, requires hospitalization or prolongation of hospitalization or results in disability/incapacity, and congenital anomaly/birth defect. Medical or scientific judgment was exercised in deciding whether reporting was appropriate. For liver injury and impaired liver function, alanine aminotransferase greater than or equal to (>=)3 times upper limit of normal (ULN) and total bilirubin >=2xULN (less than [>] 35% direct) was defined.
Local Tolerability Score for Erythema, Dryness, Peeling, Itching, and Burning or Stinging
Local tolerability score for erythema (no redness, faint red or pink coloration, barely perceptible, light red or pink coloration, medium red coloration, beet red coloration), dryness (none, barely perceptible dryness with no flakes or fissure formation, easily perceptible dryness with no flakes or fissure formation, easily noted dryness and flakes but no fissure formation, easily noted dryness with flakes and fissure formation), peeling (no peeling, mild localized peeling, mild and diffuse peeling, moderate and diffuse peeling, moderate to prominent, dense peeling) and itching and burning/stinging (normal-no discomfort, noticeable discomfort that causes intermittent awareness, continuous awareness, intermittent awareness and interferes occasionally with normal daily activities, a definite continuous discomfort that interferes with normal daily activities) was assessed on a scale of 0 to 4 (0= absent, 1= slight, 2= mild, 3= moderate and 4= severe).
Number of Participants With Severity of AEs
The severity of AEs was assessed by the investigator; events were assigned to one of the following categories: mild, an event that was easily tolerated by the participant, causing minimal discomfort and not interfering with everyday activities; moderate, an event that was sufficiently discomforting to interfere with normal everyday activities; and severe, an event that prevented normal everyday activities.
