Summary

To compare the safety and efficacy of the test (Trifarotene 0.005% cream), placebo (vehicle cream) and reference AKLIEF® (Trifarotene 0.005% cream) treatments to demonstrate clinical equivalence in subjects with acne vulgaris.

Eligibility Criteria

Inclusion Criteria

  • Male or non-pregnant, non-lactating female aged ≥ 12 and ≤ 40 years with a clinical diagnosis of acne vulgaris.
  • Subjects who are 18 years of age or older (up to the age of 40) must have provided IRB/IEC approved written informed consent. Subjects 12 to 17 years of age inclusive must have provided IRB/IEC approved written assent; this written assent must be accompanied by an IRB/IEC approved written informed consent from the Subject's legally acceptable representative (i.e., parent or guardian). In addition, all Subjects or their legally acceptable representatives (i.e., parent or guardian) must sign a HIPAA authorization.
  • Subjects must have ≥ 25 non-inflammatory lesions (i.e., open and closed comedones) AND ≥ 20 inflammatory lesions (i.e., papules and pustules) AND ≤ 2 nodulocystic lesions (i.e.,nodules and cysts), at screening/baseline on the face.

(a) For the purposes of study treatment and evaluation, these lesions should be limited to the facial treatment area. All lesions will be counted, including those present on the nose. Subjects may have acne lesions on other areas of the body which will be excluded from the count and the Investigator's Global Assessment (IGA) evaluation (e.g., on the back, chest and arms).

  • Subjects must have a definite clinical diagnosis of acne vulgaris severity grade 2, 3, or 4 as per the Investigator's Global Assessment (IGA) (per Table 1 below) at screening/baseline. Acne vulgaris should be stable (for at least 3 months prior to screening), with minimal variation from day to day and within each day, in the opinion of the subject.

Table 1: Investigator's Global Assessment (IGA) Scale for Acne Vulgaris Grade Description 0 Clear skin with no inflammatory or non-inflammatory lesions 1 Almost clear; rare non-inflammatory lesions with no more than one small inflammatory lesion 2 Mild severity; greater than Grade 1; some non-inflammatory lesions with no more than a few inflammatory lesions (papules/pustules only, no nodular lesions) 3 Moderate severity; greater than Grade 2; up to many noninflammatory lesions and may have some inflammatory lesions, but no more than one small nodular lesion 4* Severe; greater than Grade 3; up to many non-inflammatory lesions and may have some inflammatory lesions, but no more than a few nodular lesions

  • The eCRF will allow for reporting by Investigators of lesion worsening beyond Grade 4 with treatment. Acne vulgaris subjects with nodulocystic acne are not to be enrolled in the study.

Subjects who worsen beyond Grade 4 will be described in the safety evaluation. Note: Counts of nodules and cysts will be reported separately and not included in the inflammatory or non-inflammatory lesion counts.

  • Subjects must be willing to refrain from using all other topical acne medications or antibiotics during the 12-week treatment period, other than the investigational product.
  • Female subjects of childbearing potential (*WOCBP) must not be pregnant or lactating at the time of screening/baseline visit as documented by a negative urine pregnancy test with a sensitivity to at least 25 mIU/ml hCG .

*Female subjects of childbearing potential (WOCBP) are defined as sexually mature women without prior hysterectomy, or who have had any evidence of menses in the past 12 months.

However, women who have been amenorrheic for the past 12 or more months are still considered to be of childbearing potential, if the amenorrhea is possibly due to other causes, including prior chemotherapy, anti- estrogens, or ovarian suppression. Postmenopausal women (defined as women who have been amenorrheic for at least 12 consecutive months, in the appropriate age group, without other known or suspected primary cause) or women who have been sterilized surgically or who are otherwise proven sterile (i.e., total hysterectomy, or bilateral oophorectomy with surgery at least 4 weeks prior to randomization) are not considered WOCBP. Subjects who have undergone tubal ligatio
