DURHAM, N.C., June 07, 2021 (GLOBE NEWSWIRE) — Novan, Inc. (“the Company” or “Novan”) (Nasdaq: NOVN), today announced positive proof-of-concept in vitro results and informative in vivo results with its new chemical entity (NCE), NVN4100, explored as a potential product candidate for topical antimicrobial indications in companion animal health.

Novan initiated exploratory work to evaluate NVN4100 and engaged with animal health experts at Scullion Strategy Group, LLC to oversee the Company’s initial animal health studies and to assess technical feasibility and market potential. The in vivo and in vitro studies were conducted by independent third party animal health research organizations.

“We are pleased with results that further validate the anti-bacterial capabilities of our NITRICIL™ platform technology, specifically with NVN4100, a new chemical entity. The results from these exploratory studies bolster our confidence in Novan’s strategy to continue building a data package to support our strategic partnering efforts for an animal health program. These exploratory studies were an important step in confirming our initial premise that there is an opportunity for the NITRICIL™ platform technology in animal health and we believe further development and evaluations are necessary,” commented Paula Brown Stafford, President and Chief Executive Officer of Novan.

The exploratory studies were conducted to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of NVN4100 using broth dilution antimicrobial susceptibility testing against a set of clinically relevant microorganisms. Results from the in vitro assay demonstrated that NVN4100 had both inhibitory and bactericidal effects for a variety of pathogens. The tested pathogens include both antimicrobial resistant and antimicrobial susceptible strains of the most prevalent species associated with skin and ear conditions in animal health, including Escherichia coli, Pseudomonas aeruginosa, Staphylococcus pseudintermedius, and Staphylococcus schleiferi.

Additionally, in collaboration with an independent third party animal health research organization, Novan established a model of canine pyoderma, one of the most common skin conditions of dogs that is often resistant to first-line antimicrobials, to evaluate topically applied NVN4100 in an in vivo setting. The in vivo results suggest that the canine pyoderma model may serve as an appropriate tool to facilitate further development of NVN4100 as an alternative therapy to systemic and topical antimicrobials for treatment of canine superficial pyoderma or other dermatology indications.

Dr. Carri Geer, Chief Technology Officer of Novan added, “Among the results from these studies, one of the most valuable and informative outcomes of the exploratory work to date is the establishment and optimization of a clinically relevant model for canine pyoderma. The antimicrobial activity witnessed in the in vitro studies provides us with confidence in the potential broad utility of NVN4100. Those findings coupled with the establishment of the in vivo model will enable Novan to more efficiently and rapidly screen product candidates and optimize animal health targeted formulations as the development program progresses.”

“The results from the in vitro studies showed valuable insight into the potential of Novan’s innovative platform technology and the potential of NVN4100 to treat resistant strains and minimize risk of developing resistance to antibiotics in animals. Importantly, NVN4100 demonstrated that it was effective, in cultures, against a wide variety of clinically relevant bacteria including a number of Staphylococcus pseudintermedius strains, which is encouraging as the Company looks to advance its animal health program. We are encouraged by these preliminary results and look forward to further confirmation of efficacy in clinical studies, unlocking value of this program,” stated Dr. Thierry Olivry, DrVet, PhD, DECVD, DACVD, scientific advisor for Novan, and a board-certified veterinary dermatologist on Faculty for more than 26 years at North Carolina State University College of Veterinary Medicine.

Based on the results to date and the availability of funding, Novan intends to conduct additional studies and formulation work with NVN4100 to build a robust data set and engage with potential collaborators and strategic partners moving forward. The Company seeks to publish the full data set from the companion animal health exploratory studies at an upcoming scientific congress and/or in a peer-reviewed publication.

About Novan

Novan, Inc. is a clinical development-stage biotechnology company focused on leveraging its proprietary nitric oxide (NO) based technology platform, NITRICIL™ to generate macromolecular New Chemical Entities (NCEs) to treat multiple indications in dermatology, men’s and women’s health, infectious diseases, and gastroenterology conditions with significant unmet needs. The Company’s lead product candidate, SB206, a topical antiviral gel, for the treatment of molluscum contagiosum, is currently being evaluated in the B-SIMPLE4 pivotal Phase 3 clinical study. The Company believes that SB206 as a topical, at-home, caregiver-applied therapy with a rapid treatment benefit, if approved, would address an important patient-care need for the treatment of molluscum.

About NITRICIL^TM

Novan’s innovative NITRICIL™ technology leverages nitric oxide’s naturally occurring antimicrobial and immunomodulatory effects to develop new therapies for unmet medical needs across multiple therapeutic areas. NITRICIL™ stores the gaseous species on large polymers, which allow nitric oxide to be applied as timed-release chemical entities. This technology allows Novan to control the level of nitric oxide storage, the rate of release, and the molecule size for targeted delivery. The result is stabilized, druggable nitric oxide that is optimized for a specific indication.
