Detailed Description
A multicenter, randomized, double-blind, vehicle-controlled, parallel-group study comparing tazarotene foam with vehicle foam in subjects with acne vulgaris.
Approximately 742 subjects will be enrolled and randomized to 1 of the 2 study product groups in a 1:1 ratio (tazarotene foam: vehicle foam).
Subjects will apply tazarotene foam or vehicle foam to the entire face once daily for 12 weeks; study visits will occur at baseline (week 0/day 1) and at weeks 2, 4, 8, and 12.

- Negative urine pregnancy test for females of childbearing potential. • Sexually active females of childbearing potential participating in the study must agree to use a medically acceptable method of contraception while receiving protocol-assigned product. A woman of childbearing potential is defined as one who is biologically capable of becoming pregnant; including perimenopausal women who are less than 2 years from their last menses.
Women who are not currently sexually active must agree to use medically accepted method of contraception should they become sexually active while participating in the study. Male subjects and/or their partners must use a medically acceptable form of contraception.
- Capable of understanding and willing to provide signed and dated written voluntary informed consent before any protocol specific procedures are performed.
- Ability and willingness to follow all study procedures, attend all scheduled visits, and successfully complete the study.
Exclusion Criteria:

- Use of topical antibiotics on the face within the past 2 weeks.
- Use of systemic antibiotics for acne treatment within the past 4 weeks.

- Use of systemic retinoids (eg, isotretinoin) within the past 6 months.
- Treatment with estrogens, androgens, or anti-androgenic agents for 12 weeks or less immediately prior to study enrollment.

Measure Description |
Time Frame |
---|---|---|

LC: count of all inflammatory lesions (ILs, i.e., papules, pustules, and nodules) and non-inflammatory lesions (NILs, i.e., open and closed comedones) at Baseline and at Week 12.
Total lesions (TLs) were calculated as the sum of ILs and NILs.
