Novan to Present Safety and Efficacy Data for SB204 Program in Adolescents at 13th World Congress of Pediatric Dermatology

MORRISVILLE, N.C., July 07, 2017 (GLOBE NEWSWIRE) -- Novan, Inc. (“the Company” or “Novan”) (NASDAQ:NOVN) today announced that pharmacokinetic, safety and efficacy data for SB204, an investigational once-daily, topical monotherapy for the treatment of acne vulgaris, will be presented at the 13th World Congress of Pediatric Dermatology in Chicago, Illinois. New data from a post-hoc analysis of Novan’s recently completed Phase 3 pivotal trials, conducted in a subset of only adolescent subjects, showed a statistically significant reduction (p<0.05) in inflammatory, non-inflammatory and total lesion reductions with SB204 4% compared to vehicle, while maintaining a favorable safety and tolerability profile.

In two replicate, multi-center, randomized, double-blinded, vehicle-controlled, parallel group trials, a total of 2,639 patients ages 9 and older with moderate to severe acne were enrolled across 110 sites in the United States. In a post-hoc analysis of a subset of 905 adolescents ranging from ages 9 to under 17 years old, treated topically with SB204 Gel 4% once-daily (n=439) or vehicle gel once-daily (n=466) for 12 weeks, the Company found the following results (last observation carry forward methodology used for missing data).

  • The percent change from baseline in the number of non-inflammatory lesions was -33.4% for SB204 and -24.2% for vehicle (p=0.0013).
  • The percent change from baseline in the number of inflammatory lesions was -43.4% for SB204 and -36.4% for vehicle (p=0.0113).
  • The percent change from baseline in the number of total lesions was -37.4% for SB204 and -29.1% for vehicle (p<0.001).

In addition, a pharmacokinetic trial in adolescents with moderate to severe acne assessed systemic exposure following topical application of SB204. No systemic exposure to markers for nitric oxide exposure under maximal use conditions was detected.

“It is encouraging to see a potential new therapy, with positive data, in development for the treatment of acne in adolescents,” said Diane Thiboutot, M.D., practicing dermatologist at The Milton S. Hersey Medical Center in Hersey, PA and professor of Dermatology at the Pennsylvania State University College of Medicine. “Acne is one of the most common skin conditions in children and teenagers, and its reach is far beyond the physical effects of the disease, extending to anxiety, depression and low self-esteem. A therapy that safely addresses the acne lesions without bothersome side effects is an unmet need for physicians, patients and parents.”

These data in an adolescent population follow the recent presentation of new findings into the potential mechanism of action of SB204 at the Dermatology Summer Symposium of the Alabama Dermatology Society in Sandestin, Florida on June 23, 2017.

In an ex-vivo human skin model designed to assess the anti-inflammatory effects of topical treatments against a toll-like receptor-stimulated overexpression of cytokines in healthy, human skin biopsies, Novan observed that a single application of SB204 4% significantly inhibited the upregulation of IL-1β by approximately 62% as compared to untreated controls (n of 6 donors, p=0.045). IL-1β is an inflammatory cytokine known to be involved in the pathogenesis of acne, with a fifty-fold increased presence in papulopustular acne lesions versus normal human skin.1 These findings support the hypothesis that the mechanism of anti-inflammatory effect of nitric oxide in acne prone skin is mediated by the inactivation of the NLRP3 inflammasome previously reported by Friedman and co-workers.2

Novan intends to request a follow up meeting with the U.S. Food and Drug Administration (“FDA”) in the third quarter of 2017 to discuss the path forward for the development of SB204 for the treatment of acne from both a clinical and regulatory perspective.

About Novan

Novan, Inc. is a late-stage pharmaceutical company focused on redefining the standard of care in dermatology through the development and commercialization of innovative therapies using the Company’s nitric oxide-releasing platform. Nitric oxide plays a vital role in the natural immune system response against microbial pathogens and is a critical regulator of inflammation. Our ability to harness nitric oxide and its multiple mechanisms of action has enabled us to create a platform with the potential to generate differentiated, first-in-class product candidates. We are rapidly advancing programs in five dermatological conditions with significant unmet medical need. We believe that our ability to conveniently deploy nitric oxide on demand in topical formulations allows us the potential to significantly improve patient outcomes in a variety of skin diseases and positions us to be a commercially successful leader in the dermatology market.
