Vical and Astellas Announce Worldwide License Agreements for TransVax™ Cytomegalovirus Vaccine

SAN DIEGO and TOKYO, July 14, 2011 (GLOBE NEWSWIRE) -- Vical Incorporated (Nasdaq:VICL) and Astellas Pharma Inc. (TOKYO:4503) today announced that they have signed exclusive license agreements for the United States and for all territories in the rest of world outside the United States to develop and commercialize TransVaxTM, Vical's therapeutic vaccine designed to control cytomegalovirus (CMV) reactivation in transplant recipients. The companies expect to begin a multinational Phase 3 registration trial of TransVaxTM in hematopoietic stem cell transplant (HSCT) recipients as well as a Phase 2 trial in solid organ transplant (SOT) recipients in the first half of 2012. The agreements will become effective subject to the expiration or termination of the applicable 30-day waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.

Under the agreements, Astellas will be responsible for further development and commercialization, including all costs. Vical has an option to co-promote TransVaxTM in the United States. Vical will provide assistance to Astellas with TransVaxTM-related manufacturing, regulatory and certain development activities, for which Astellas will reimburse all of Vical's future costs, including personnel and external expenses. Vical will receive near-term payments of $35 million, including $25 million upon the effective date and $10 million upon finalization of the Phase 3 trial design. Vical potentially will receive up to $130 million in total upfront and milestone payments through commercial launch and double-digit royalties on net sales.

"We are very pleased to work with Vical on the development and commercialization of TransVaxTM as Astellas is committed to reinforcing its vaccine business," said Yoshihiko Hatanaka, President and Chief Executive Officer of Astellas. "The impressive results from the TransVaxTM Phase 2 trial provided evidence of safety, immunogenicity and efficacy in a highly challenging HSCT recipient patient population, and reinforce our confidence for future success. We are excited to advance this program toward commercialization to offer transplant recipients a vaccine option for potentially safe and effective control of CMV."

"We believe Astellas is ideally positioned to help us drive this key program toward its greatest potential success," said Vijay Samant, President and Chief Executive Officer of Vical. "Our first-in-class CMV vaccine would complement the existing Astellas franchise in the transplant market, a strategic focus area for Astellas. This program will bring together Astellas' substantial resources and strong commercial presence in key world markets, and Vical's development, regulatory and manufacturing expertise with DNA-based product candidates. We are excited to work with Astellas in advancing TransVaxTM toward commercialization."

About TransVaxTM

TransVaxTM is a bivalent DNA vaccine containing plasmids (closed loops of DNA) encoding CMV pp65 and gB antigens for induction of both cellular and humoral immune responses. TransVaxTM is formulated with a proprietary poloxamer-based delivery system. TransVaxTM has received orphan drug designation in the United States for HSCT and SOT patients.

About CMV

CMV is a herpes virus that infects more than half of all adults in the United States by age 40, and is even more widespread in developing countries. While a healthy immune system typically protects an infected person against CMV disease, it rarely succeeds in eliminating the infection, and those whose immune systems are not fully functional are at high risk of CMV reactivation, potentially leading to severe illness or death. Those at greatest risk include transplant patients and infants born to mothers who first become infected during pregnancy. Vical is pursuing two different vaccine approaches for these distinct market segments: TransVaxTM for the transplant market and CyMVectinTM for the congenital disease market.
