Juvaris BioTherapeutics Completes Second Close on $25 Million Series B Financing
Strategic Corporate Investor Joins Syndicate

BURLINGAME, Calif.--(BUSINESS WIRE)--Juvaris BioTherapeutics, Inc., a biotechnology company developing adjuvanted vaccines for infectious diseases, announced that it has completed a second close on its Series B equity financing of up to $25 million. The additional equity investment came from an undisclosed strategic corporate investor who joins SV Life Sciences and Kleiner Perkins Caufield & Byers in the round.

"We are pleased to further strengthen our investor syndicate in advance of completing our ongoing Phase 2 study of JVRS-100 in mid-2010 and as we continue to advance our promising vaccine portfolio"
.The funds will be used to advance Juvaris' novel adjuvant platform of cationic-lipid DNA complexes, which are designed to significantly improve the quality and quantity of immune responses achievable with vaccines, along with the Company's proprietary adjuvanted vaccine pipeline. Juvaris has shown in clinical development that its lead adjuvant, JVRS-100, produces significant T-cell mediated immune responses and improved antibody responses without evidence of toxicity. JVRS-100 is currently being studied in a 472 subject Phase 2 clinical study to demonstrate its ability to improve seasonal flu vaccines for the elderly population, where there is a significant unmet medical need. Juvaris is also advancing JVRS-100 into clinical development to improve pandemic influenza vaccines and developing a pipeline of proprietary adjuvanted vaccines that includes a HSV-2 (genital herpes) vaccine and a universal influenza vaccine.

"We are pleased to further strengthen our investor syndicate in advance of completing our ongoing Phase 2 study of JVRS-100 in mid-2010 and as we continue to advance our promising vaccine portfolio," said Grant Pickering, Juvaris President and Chief Executive Officer.

About Juvaris

Juvaris BioTherapeutics is a clinical stage company developing adjuvanted vaccines to treat infectious diseases. The Company's lead adjuvant, JVRS-100, is a cationic lipid-DNA complex that is being developed as an adjuvant to improve the effectiveness of existing vaccines and to develop new vaccines against a variety of infectious diseases. Research indicates that the mechanism of action of JVRS-100 is distinct from other known adjuvants. The adjuvant complex self-assembles with disease-specific antigens and induces substantial antibody- and cell-mediated immune responses, particularly induction of CD4+ and CD8+ T lymphocytes. Significant immunological responses have been elicited by JVRS-100 in both prophylactic and therapeutic vaccine settings in multiple species. This platform provides the opportunity to develop many disease-specific immunotherapy products for which there are significant unmet medical needs. Juvaris is also developing JVRS-100 as a component of novel, proprietary vaccines against a variety of infectious diseases.
