Forward Science licenses cold sore drug Sitavig from EPI Health
Forward Science and EPI Health, a wholly owned subsidiary of EPI Group, have entered into an exclusive agreement licensing Sitavig to Forward Science in the dental market. Sitavig, FDA-approved since April 2013, is indicated for the treatment of recurrent herpes labialis, or cold sores, in immunocompetent adults.
Cold sores, also called fever blisters, are common viral infections that are caused most often by the herpes simplex virus (HSV-1). Cold sores are contagious even if you do not see the sores. Antiviral medications can help cold sores heal more quickly and may reduce how often they return, however there is no cure for HSV infection. The current method of treating cold sores is to alleviate the symptoms, reduce the duration of the outbreak, and reduce the number of outbreaks.
“We are excited to continue to bring advanced products to the dental market that frequently get overlooked," said Forward Science CEO Robert J. Whitman. “As physicians of the mouth, [dentists have] an opportunity to change lives affected from the negative stigma of cold sores, and Sitavig is the best product to do that with."
The most common treatment method currently used for cold sores is prolonged systemic dosing of acyclovir. "Sitavig's active drug is also acyclovir, but its proprietary delivery system produces several distinct advantages over the current standard of treatment," said Brian Pikkula, Forward Science chief technology officer.
Sitavig is a single dose, which dramatically increases compliance and ease of use for the patient. More importantly, the local targeting of Sitavig to the oral mucosa provides a marked increase in salivary concentration of the active drug where it is needed, while at the same time giving orders of magnitude lower plasma concentration of acyclovir resulting in reduced side effects. Because of the locally targeted therapy, a third of patients in the clinical trial did not progress to break out and those with recurrent cold sores experienced a significant delay before their next episode.
"Sitavig has predominately been marketed to the dermatology market with much success," said Chuck Jenkins, EPI VP of commercial operations and strategy. "Forward Science has shown success in launching new products to the dental market, and we are excited to partner with them in efforts to get Sitavig to more patients."
