Efficacy and Safety of IDP-121 and IDP-121 Vehicle Lotion in the Treatment of Acne Vulgaris

The objective of this study was to evaluate the efficacy, safety, and tolerability of a once daily topical application of IDP-121 Lotion compared with its vehicle (IDP-121 Vehicle Lotion) in participants with moderate to severe acne vulgaris (acne) (that is, acne having an Evaluator's Global Severity Score [EGSS] of 3 [moderate] or 4 [severe]).

Only the study team can determine whether someone qualifies for participation.

Key Inclusion Criteria:

  • Male or female at least 9 years of age and older.
  • Written and verbal informed consent must be obtained. Participants less than age of consent must sign an assent for the study and a parent or a legal guardian must sign the informed consent (if participant reaches age of consent during the study they should be re-consented at the next study visit).
  • Participant must have a score of 3 (moderate) or 4 (severe) on the EGSS assessment at the screening and baseline visit

Key Exclusion Criteria:

  • Use of an investigational drug or device within 30 days of enrollment or participation in a research study concurrent with this study.
  • Any dermatological conditions on the face that could interfere with clinical evaluations such as acne conglobata, acne fulminans, secondary acne, perioral dermatitis, clinically significant rosacea, gram-negative folliculitis.
  • Any underlying disease(s) or some other dermatological condition of the face that requires the use of interfering topical or systemic therapy or makes evaluations and lesion count inconclusive.
  • Participants with a facial beard or mustache that could interfere with the study assessments.

Primary outcomes

  1. Absolute Change From Baseline in Mean Noninflammatory Lesion Count to Week 12

    Time frame: Baseline (Day 0), Week 12

    Noninflammatory lesions were defined as follows: Open comedones (blackhead) - plugged hair follicle with dilated/open orifice, black in color; and Closed comedones (whitehead) - plugged hair follicle: small opening at skin surface. For noninflammatory facial lesions, open and closed comedones were recorded as a single count.

  2. Absolute Change From Baseline in Mean Inflammatory Lesion Count to Week 12

    Time frame: Baseline, Week 12

    Inflammatory lesions were defined as follows: Papule - a solid, elevated lesion less than 5 millimeters (mm); and Pustule - an elevated lesion containing pus less than 5 mm. For inflammatory facial lesions, papules and pustules were recorded as a single count, while nodular lesions were counted and recorded separately.

  3. Percentage of Participants With Treatment Success at Week 12

    Time frame: Baseline, Week 12

    Treatment success was defined as at least a 2-grade reduction from Baseline in EGSS score and an EGSS score equating to "Clear" or "Almost Clear". EGSS was based on a 5-point scale ranging from 0 to 4; where 0 = clear, 1 = almost clear, 2 = mild, 3 = moderate, and 4 = severe.

Secondary outcomes

  1. Percent Change From Baseline in Noninflammatory Lesion Count to Week 12

    Time frame: Baseline, Week 12

    Noninflammatory lesions were defined as follows: Open comedones (blackhead) - plugged hair follicle with dilated/open orifice, black in color; and Closed comedones (whitehead) - plugged hair follicle: small opening at skin surface. For noninflammatory facial lesions, open and closed comedones were recorded as a single count.

  2. Percent Change From Baseline in Inflammatory Lesion Count to Week 12

    Time frame: Baseline, Week 12

    Inflammatory lesions were defined as follows: Papule - a solid, elevated lesion less than 5 millimeters (mm); and Pustule - an elevated lesion containing pus less than 5 mm. For inflammatory facial lesions, papules and pustules were recorded as a single count, while nodular lesions were counted and recorded separately.
