Data Reinforces Importance of Scar Prevention as an Important Goal of Acne Treatment

FT. WORTH, Texas – (April 30, 2018) – Galderma, a global leader focused on medical solutions for skin health, announces positive results from OSCAR, a phase 4 trial, a multicenter, randomized, investigatorblinded, vehicle-controlled, intra-individual comparison study (right/left half-face).1 The purpose of OSCAR was to evaluate the efficacy of Epiduo® Forte (adapalene and benzoyl peroxide) Gel, 0.3%/2.5% in the treatment of moderate-to-severe acne and to understand if, by decreasing active acne lesions, Epiduo Forte Gel could thereby decrease the risk of atrophic (depressed) acne scars. 1 The OSCAR results were published in the American Journal of Clinical Dermatology.

Results demonstrated Epiduo Forte Gel significantly decreased acne lesions, as measured over a period of 24 weeks vs. vehicle (P < .0001), with acne lesion reduction as early as week one.1 At week 24, a significantly larger percentage of subjects were Investigator’s Global Assessment (IGA) clear/almost clear with Epiduo Forte Gel treatment (64.2 percent vs. 19.4 percent vehicle, P < .0001).2,3 Furthermore, by rapidly and effectively treating acne, Epiduo Forte Gel also reduced the risk of atrophic acne scars in patients with moderate-to-severe acne.1 Through the effective reduction of acne lesions, the overall Scar Global Assessment (SGA) also improved by week 24 in the portion of the face treated with Epiduo Forte Gel (32.9 percent clear/almost clear vs. 16.4 percent vehicle, P < .01).2,3 According to a patient satisfaction survey, overall, 90.1 percent were satisfied to very satisfied with Epiduo Forte Gel vs. 59 percent with vehicle.2

"Acne scarring impacts approximately 40 percent of people who currently have acne.4 While significant advances have been made in treating acne, there is an unmet need to understand how we can best reduce the risk of acne scarring,”5 said Jerry Tan, M.D., fellowship certified specialist in dermatology and adjunct professor, Schulich School of Medicine and Dentistry, Department of Medicine, University of Western Ontario, principal investigator of the OSCAR trial, and paid Galderma consultant. “Results from the OSCAR study show that treating acne lesions early and effectively with Epiduo Forte Gel can reduce the risk of atrophic acne scars.”1,6

Acne is the most common skin condition in the United States, affecting up to 50 million Americans annually, including approximately 85 percent of teenagers and young adults. 7 Not only can acne be associated with embarrassment, anxiety and depression, it also has the potential to leave permanent physical scars. 7,8,9 Scarring can occur with any acne severity.10 In fact, nearly six percent of acne lesions may become scars and the risk for acne scarring increases with delays in treatment.11,12

“We are pleased to share these positive findings that underscore the efficacy and tolerability of Epiduo Forte Gel in the treatment of acne,”1,13 said Chris Chapman, Vice President and General Manager of Galderma’s U.S. Prescription Business. "We hope that the learnings from the OSCAR study will help empower clinicians to view scar risk reduction as a key consideration within the acne treatment paradigm.”1,6

In the study, Epiduo Forte Gel was safe and well tolerated with the most common treatment-related adverse event (AE) being mild to moderate skin irritation (15 percent vs. six percent, vehicle).1,13 There were no serious or severe AEs in the study, and the vast majority of related AEs were mild in intensity.1

About the OSCAR Study

The OSCAR study was a multicenter, randomized, investigator-blinded, vehicle-controlled, intraindividual comparison study (right/left half-face).1 Subjects received 24 weeks of treatment with Epiduo Forte Gel or vehicle (half-face) and full-face skin care.1 At 24 weeks, based on satisfactory investigatorassessed efficacy and subject agreement, subjects could be treated with once-daily Epiduo Forte Gel on the full face for up to 24 additional weeks with two additional visits at weeks 36 and 48.1 Assessments included acne lesions, Investigator Global Assessment (IGA), investigator atrophic acne scar count, Scar Global Assessment (SGA), and safety/tolerability.1


About Epiduo® Forte Gel

Epiduo® Forte (adapalene and benzoyl peroxide) Gel, 0.3%/2.5% is a once-a-day prescription medication, FDA approved for the treatment of acne vulgaris. It combines two powerful medicines to treat tough acne now and helps prevent recurring acne from forming by unclogging pores and killing bacteria without the use of antibiotics.

Epiduo Forte Gel contains the highest concentration of the retinoid adapalene to reduce the inflammation associated with moderate to severe acne. If left untreated, inflammatory acne can lead to permanent scarring.7,8


About Acne and Acne Scarring

Acne is the most common skin condition in the United States, affecting up to 50 million Americans annually and approximately 85 percent of teenagers and young adults. 7 It is caused by a combination of sebum (oil) and dead skin cells, which clog pores, allowing the bacteria associated with acne (p. acnes) to grow.7,14 Approximately 40 percent of people with acne have scars.4 Notably, each acne lesion has a nearly six percent risk of becoming a scar.11 Acne scars can begin early on in the course of the disease of acne and new scar formation can persist continuously until acne resolves, reinforcing the importance of early and effective treatment to avoid acne leaving a lasting mark.6,7,15 Not only can acne leave physical scars, it can also leave psychological and emotional scars including negative impacts on self-image and psychological well-being, anxiety, depression, lower self-esteem and negative emotions.7,8,16
