Acne Vulgaris
Conditions
Brief summary
The study hypothesis are based on the assumption that : * CD0271 0.3%/CD1579 2.5% Gel provides superior clinical efficacy compared with Topical Gel Vehicle in the overall population and in the subgroup of severe Subjects * CD0271 0.3%/CD1579 2.5% Gel applied once daily for up to 12 weeks has an acceptable safety and tolerability profile

Eligibility
Inclusion criteria
1. Male or female, who is 12 years of age or older at Screening visit. 2. Clinical diagnosis of acne vulgaris with facial involvement. 3. An IGA of Moderate (3) or Severe (4) at Baseline visit. 4. A minimum of 20 but not more than 100 inflammatory lesions (papules and pustules) on the face (including the nose) at Baseline visit. 5. A minimum of 30 but not more than 150 non-inflammatory lesions (open comedones and closed comedones) on the face (including the nose) at Baseline visit.
Exclusion criteria
1. More than 2 acne nodules on the face at Baseline visit. 2. Acne conglobata, acne fulminans, secondary acne (chloracne, drug-induced acne, etc.), nodulo cystic acne, or acne requiring systemic treatment. 3. Underlying diseases or other dermatologic conditions that require the use of interfering topical or systemic therapy or that might interfere with study assessments such as, but not limited to, atopic dermatitis, perioral dermatitis or rosacea. This includes clinically significant abnormal findings, uncontrolled or serious disease, or any medical or surgical condition, that may either interfere with the interpretation of the clinical trial results, and/or put the subject at significant risk (according to Investigator's judgment) if he/she participates in the clinical trial. 4. The subject has received, applied or taken some specified treatments within the specified timeframe prior to the Baseline visit 5. The subject is unwilling to refrain from use of prohibited medication during the clinical trial. 6. Use of hormonal contraceptives solely for control of acne.

Success Rate
Success was defined as 'Clear' or 'Almost Clear' on the Investigator Global Assessment (IGA). Success rate at Week 12 was estimated using multiple imputation approach which is an average of response from multiple imputed datasets.
Time frame: Week 12
Population: Intent-to-treat (ITT): All subjects who were randomized. Baseline IGA Severe population: All randomized subjects who had IGA=4 at baseline.
