Effective against viral acute retinal necrosis

Dr. Vivien Boniuk, Consultant in Ophthalmology at the Company, presented the successful results of certain anti-herpes nanoviricide treatments for v-ARN at the 2017 Annual meeting of the Ocular Microbiology and Immunology Group (OMIG) of the American Academy of Ophthalmology held in New Orleans, LA, on November 10, 2017. In this study, HSV-2 infection was given to mice as a single injection to cause v-ARN. The mice that received either of two nanoviricides drug candidates simultaneously with the virus in this single injection, showed significant improvements using a number of parameters. In contrast, mice that received foscarnet injection simultaneously with the virus did not show any improvements. Of note, foscarnet is a current standard of treatment, although the treatment is long in duration and arduous, being multiple intravitreal injections. In addition, another group of HSV-2 infected animals received acyclovir by intraperitoneal injection (50mg/kg), twice daily for 7 days, as a positive control. Acyclovir and its derivatives are also used currently for treating v-ARN, although the clinical efficacy is limited and generally requires long durations of treatment. Vehicle treated and untreated negative controls also were employed. These studies were performed in the lab of Dr. Curtis Brandt at CORL, University of Wisconsin, Madison, WI.

Both nanoviricides tested showed remarkable efficacy using multiple parameters. In particular, nanoviricide-A treated group showed viral load going down to undetectable levels by day 7 itself (approximately 4 logs viral load reduction from baseline), whereas acyclovir group showed no reduction in viral load from baseline at day 7, but approximately 2 logs reduction at day 9, indicating a much lower efficacy.
