ARAZLO Lotion Demonstrated Statistically Significant Superiority Over Placebo with Favorable Efficacy, Safety and Tolerability Profile

Post Hoc Analysis of the Two Phase 3 Studies Also Published in JDD

BRIDGEWATER, N.J., Jan. 13, 2020 /PRNewswire/ — Bausch Health Companies Inc. (NYSE/TSX: BHC) and its dermatology business, Ortho Dermatologics, one of the largest prescription dermatology health care businesses, today announced that the Journal of Drugs in Dermatology (JDD) published positive results from two large Phase 3, multicenter, double-blind, placebo-controlled clinical trials (Studies 1 and 2) demonstrating the efficacy, safety and tolerability of ARAZLOTM (tazarotene) Lotion, 0.045%, the first FDA approved tazarotene in lotion form for patients with moderate to severe acne.1 A post hoc analysis of male patients in the two Phase 3 studies was also published by JDD.2 The U.S. Food and Drug Administration (FDA) approved ARAZLO for the topical treatment of acne vulgaris in patients nine years of age and older in December 2019.

«When treating moderate to severe acne, I like to prescribe a tazarotene treatment due to the retinoid’s efficacy, but find patients often struggle with tolerability issues, such as dry, irritated skin,» said Emil A. Tanghetti, M.D., lead ARAZLO study investigator and founder, Center for Dermatology and Laser Surgery, Sacramento, Calif. «This newly published data sheds light on the utility of ARAZLO, a new treatment option that features the efficacy of tazarotene along with improved tolerability in a lotion vehicle, which is easily spreadable and aesthetically pleasing. I look forward to offering this treatment to my patients with acne in the coming months.»

The first primary endpoint in the pivotal studies (Studies 1 and 2) was treatment success (defined as those with at least a two-grade improvement in Evaluator’s Global Severity Score (EGSS), and ‘clear’ or ‘almost clear’ skin) measured at week 12. The data showed that ARAZLO was more effective, with 25.5 percent and 29.6 percent of patients achieving treatment success compared with 13.0 percent and 17.3 percent in the placebo arms of Studies 1 and 2, respectively (p<0.001 for both studies).1

The second primary endpoint in the pivotal studies was absolute reduction in inflammatory and noninflammatory lesion counts at week 12. The data from Studies 1 and 2 showed that ARAZLO was more effective than placebo, with reductions of 15.6 and 16.7 inflammatory lesion counts from baseline, compared to 12.4 and 13.4 in the placebo arms. Non-inflammatory lesion count reductions were 21.0 and 24.6 versus 16.4 and 16.6 in the placebo arms of the two studies, respectively (p<0.001 for both studies).1

In a pooled analysis of Studies 1 and 2, the most common treatment-related adverse events of ARAZLO compared to placebo were application site pain (5.3 percent vs 0.3 percent), dryness (3.6 percent vs 0.1 percent), exfoliation (2.1 percent vs 0.0 percent) and erythema (1.8 percent vs 0.0 percent).1

«These data, combined with our recent FDA approval of ARAZLO, demonstrate our continued commitment to bringing treatment innovations to market that meet the ever-evolving needs of dermatologists and their patients who struggle with acne,» said Bill Humphries, president, Ortho Dermatologics. «We look forward to launching the product later this year, providing dermatologists with a lower concentration of tazarotene lotion that helps effectively clear moderate to severe acne.»

In addition to the results from the two Phase 3 studies, JDD also published results from a post hoc analysis of efficacy in both adult (18 years and older) and adolescent (less than 18 years old) male patients with moderate or severe acne from the Phase 3 studies. Overall, the post hoc analysis found that ARAZLO was more effective and better tolerated in adult males compared to adolescent males, with better results also reported compared to the overall study population.2 

About the Phase 3 Studies (Studies 1 and 2)
Studies 1 and 2 were multicenter, double-blind, randomized, placebo-controlled, parallel-group Phase 3 studies. The studies evaluated the safety, tolerability and efficacy of ARAZLOTM (tazarotene) Lotion, 0.045%, in 1,614 patients with moderate or severe acne, as determined by the EGSS.

Patients were randomized to receive ARAZLO or placebo lotion, and all patients who were provided the study drug were included in the intent-to-treat (ITT) population. The co-primary endpoints were EGSS and absolute reduction in inflammatory and non-inflammatory lesion counts. Patients who had at least a two-grade reduction from baseline EGSS at week 12, and an EGSS of ‘clear’ or ‘almost clear’ were considered a treatment success. Secondary endpoints included percent change in both lesion counts from baseline at each study visit and absolute change in Acne-Specific Quality of Life questionnaire (Acne-QoL) domain scores. Safety, adverse events (AEs) and cutaneous tolerability were evaluated throughout the study.
