About BioVex
BioVex is a privately held biotechnology Company based in Woburn. MA.  The Company is developing a new class of potent biologics for the treatment of cancer and prevention of infectious disease.

BioVex's lead cancer program, OncoVEXGM-CSF, is an oncolytic virus that selectively destroys tumor cells accompanied by the induction of a systemic immune response.  OncoVEXGM-CSF is currently completing a Phase II clinical trial for melanoma and Phase I/II clinical trials for head & neck cancer and pancreatic cancer. Preliminary data from these studies has been very encouraging demonstrating OncoVEXGM-CSF has the potential to treat both local and metastatic disease. The Company is currently preparing for an initial registration study in melanoma where multiple responses have been demonstrated in an ongoing Phase II trial testing OncoVEXGM-CSF as stand alone therapy in patients with un-resectable stage IIIc or stage IV metastatic disease.

The Company's second program is a vaccine for genital herpes, ImmunoVEXHSV2, which provides complete protection in animal models of the disease. A Phase I study with ImmunoVEXHSV2 is scheduled to initiate at the end of the year. For more information visit the company’s website at www.biovex.com
