study comparing trifarotene cream, 0.005% to aklief ® (trifarotene 0.005% cream) in the treatment of acne vulgaris

Conditions: Acne Vulgaris

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.

to compare the safety of test, reference, and placebo treatments in patients with acne vulgaris. subjects in this randomized, double-blind, three-arm, placebo controlled, parallel-design, multi-site study will be randomly assigned in a 1:1:1 ratio to treatment with the test product, reference product or placebo control, respectively.

Eligibility criteria:
inclusion criteria: 1. male or non-pregnant, non-lactating female aged ≥ 12 and ≤ 40 years with a clinical diagnosis of acne vulgaris. 2. 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. 3. 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). 4. 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. 5. 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. 6. 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 ligation are not considered as surgically sterile. 7. female subjects of childbearing potential must be willing to use an acceptable form of birth control during the study from the day of the first dose administration to 30 days after the last administration of study drug. 1. for the purposes of this study the following are considered acceptable methods of birth control: oral or injectable contraceptives, contraceptive patches, medroxyprogesterone acetate (ex. depo-provera®) with stabilized use for at least 3 months, vaginal contraceptive (ex. etonogestrel/ethinyl estradiol vaginal ring (ex. nuvaring®), contraceptive implant with etonogestrel or equivalent, double barrier methods, (e.g. condom and spermicide), intrauterine device (iud), true abstinence (if in line with subject's lifestyle). 2. if a subject who was abstinent becomes sexually active during the study, a 2nd acceptable method of birth control should be used and documented. 3. subjects on hormonal contraception must be stabilized on the same type for at least three months prior to enrollment in the study and must not change the method during the study. a sterile sexual partner is not considered an adequate form of birth control. 8. female subjects who are premenarchal, surgically sterilized (by \*hysterectomy or bilateral oophorectomy) or postmenopausal for at least 1 year (defined as women who have been amenorrheic for at least 12 consecutive months, without other known or suspected primary cause). 9. all male subjects must agree to use accepted methods of birth control with their partners, from the day of the first dose administration to 30 days after the last administration of study drug. true abstinence is an acceptable method of birth control if in line with subject's lifestyle. female partners should use an acceptable method of birth control as described in the above criteria 7. 10. subjects must be willing and able to understand and comply with the requirements of the protocol, including attendance at all required study visits and refraining from the use of all other topical acne medications or antibiotics during the 12-week treatment period. 11. subjects must be in good health and free from any clinically significant disease, which may interfere with the evaluation of acne vulgaris or the administration of the investigative product. 12. subjects who use make-up must have used the same brands/types of make-up for a minimum period of 14 days prior to study entry and must agree to not change make-up brand/type or frequency of use throughout the study. exclusion criteria: 1. female subjects who are pregnant, lactating or
