ContraVir Pharmaceuticals Closes $9.0 Million Financing to Advance Lead Shingles Candidate

Proceeds to Fund Phase 2b Study of FV-100 Fast-Acting Oral Antiviral

Edison, NJ, October 15, 2014 — ContraVir Pharmaceuticals, Inc. (OTCBB:CTRV), a biopharmaceutical company focused on the development and commercialization of targeted antiviral therapies, announced today that it has closed a private placement of shares of Series A Convertible Preferred Stock to a non-U.S. investor with gross proceeds of $9.0 million.  The Preferred Stock is convertible at any time into shares of common stock at a conversion price of $0.48 per share.  The investor has agreed to lock-up the shares of Preferred Stock and the underlying common stock until April 14, 2016.

ContraVir intends to use the net proceeds of the transaction to fund the previously announced initiation of a Phase IIb clinical study for the Company’s lead clinical asset, FV-100, a fast acting, low dose, once-daily oral antiviral agent being developed for the treatment of herpes zoster, or shingles, which is an infection caused by the reactivation of varicella zoster virus. FV-100 also has the potential to further reduce the incidence, severity, and duration of shingles-associated pain and prevent post-herpetic neuralgia (PHN).

James Sapirstein, Chief Executive Officer, stated, “This $9.0 million financing is the first step in a corporate and clinical strategy to accelerate the growth of ContraVir and seize upon the significant potential of FV-100. Not only are we now capitalized to initiate the Phase IIb clinical trial of FV-100 in shingles, but we are also well positioned to target additional opportunities to add to our pipeline and build ContraVir as a multifaceted antiviral company.”

About ContraVir Pharmaceuticals

ContraVir is a biopharmaceutical company focused on the discovery and development of targeted antiviral therapies. ContraVir’s lead candidate, FV-100, is an orally available nucleoside analogue prodrug that is being developed for the treatment of herpes zoster, or shingles, which is an infection caused by the reactivation of varicella zoster virus (VZV).

Published preclinical studies demonstrate that FV-100 is significantly more potent against VZV than acyclovir, famcyclovir, and valacyclovir, the FDA approved drug for treating shingles. Moreover, FV-100 has been shown to have a more rapid onset of antiviral activity in preclinical models, and may fully inhibit the replication of VZV more rapidly than these drugs at significantly lower concentration levels and with a better dosing regimen. Phase I trials of FV-100 in volunteers were successfully completed, as well as a Phase IIa clinical trial in shingles patients. ContraVir plans to conduct a Phase IIb trial in patients with shingles to further explore FV-100’s potential to treat the long-lasting nerve pain typically associated with shingles. ContraVir was formed in May 2013 by Synergy Pharmaceuticals, Inc. (NASDAQ:SGYP) and spun off as an independent public company in January 2014. For more information, please visit www.contravir.com.
