Topical treatment for cold sores achieves efficacy of oral drugs; represents paradigm shift

NanoBio scientists credit the topical lotion's safety and robust anti-infective activity to NB-001's novel technology platform. The lotion is composed of an oil-in-water emulsion and a commonly used antimicrobial surfactant that are mixed at high speeds to nanosize the particles and infuse them with high levels of potential energy. The resulting nanodroplets easily penetrate hair follicles and skin pores to reach the site of infection without damaging skin or mucous membranes. Upon contact with the pathogen, the highly charged particles release their energy to the pathogen's outer membranes, disrupting the viral particle.

"The ability of NB-001 to penetrate skin pores and hair follicles is essential to its activity in the dermis and epidermis, where it surrounds and fuses with herpes simplex virus and disrupts the outer envelope of the pathogen," Flack said. "NB-001 does not compromise tissue integrity, so it is not absorbed into the bloodstream."

Because the herpes simplex virus causes both cold sores and genital herpes, there is a strong potential that NB-001 will also be effective in treating genital lesions, she added.

NanoBio is currently testing its pipeline of topical products against a wide range of skin infections including onychomycosis (nail fungus), tinea capititis (ringworm) and acne.
