To compare the safety and efficacy profiles of Tazarotene Cream, 0.1 % to the reference listed drug Tazorac® (tazarotene) Cream, 0.1 % in order to demonstrate bioequivalence, and to demonstrate superiority of the 2 active creams over that of the cream vehicle (placebo) in the treatment of acne vulgaris.
This is a randomized, placebo-controlled, parallel-group, multicenter, double-blind study of Tazarotene Cream, 0.1% in subjects with acne vulgaris. Subjects will be assigned in a 1:1:1 ratio to test product, reference product, or cream vehicle. Subjects will be admitted into the study only after written informed consent has been obtained and all of the inclusion and none of the exclusion criteria have been met. Randomized subjects will apply the study medication once daily in the evening for 12 weeks (84 days).

| Measure | Description | Time Frame |
|---|---|---|
| Evaluation of equivalence of the test product to the reference product | The primary evaluation of equivalence will be through 2-sided 90% confidence intervals (CIs) about the ratio in mean percent reduction from baseline to Visit 4/Week 12 in the number of inflammatory and non-inflammatory lesions, respectively, of the test product to the reference product. These evaluations are based on a normal distribution adjusted for the effects of treatment group and site. | Week 12 |
| Evaluation of superiority | The primary evaluation of superiority will be conducted using an analysis of variance (ANOVA) model on the mean percent reduction in inflammatory and non-inflammatory lesions, respectively, with treatment and site as fixed effects. Contrasts will be performed to compare each active treatment with the vehicle cream. | Week 12 |
| Measure | Description | Time Frame |
|---|---|---|
| Proportion of subjects with a clinical response of "success" | The secondary efficacy endpoint will include the proportion of subjects with a clinical response of "success" at Visit 4/ Week 12. Success is defined as an Investigator's Global Assessment (IGA) score that is at least 2 grades less than the baseline assessment. | Week 12 |
