Takeda to Acquire LigoCyte Pharmaceuticals, Inc.

Gains First-in-Class Norovirus Vaccine Candidate and Virus-Like Particle Platform, Advancing Takeda's Commitment to Vaccines and Global Public Health

OSAKA, Japan, DEERFIELD, Ill. and BOZEMAN, Mont., October 04, 2012, 2012 /PRNewswire/ -- Takeda Pharmaceutical Company Limited (Takeda) and LigoCyte Pharmaceuticals, Inc. jointly announced today that Takeda's wholly-owned subsidiary, Takeda America Holdings, Inc. and LigoCyte Pharmaceuticals, Inc. have entered into a definitive agreement for Takeda to acquire LigoCyte for an upfront payment of $60 million, with future contingent consideration based on the progress of development projects. LigoCyte is a privately-held biopharmaceutical company specializing in innovative vaccine products headquartered in Bozeman, Montana. Its lead product, a vaccine to prevent norovirus gastroenteritis, is in phase I/II of clinical development.

"Takeda's acquisition of LigoCyte is a major step forward in the expansion of Takeda's vaccine business, and a demonstration of Takeda's dedication to preventing illness in children and adults around the world," said Rajeev Venkayya, M.D., executive vice president of Takeda's Vaccine Business Division (VBD), which was launched in January 2012. "Norovirus is the most common cause of outbreaks of gastroenteritis and foodborne illness in the U.S., and is responsible for 200,000 deaths each year, most of them in developing countries. With the only norovirus vaccine in clinical trials today, Takeda will be in a position to change this picture."

LigoCyte is focused on the development of innovative vaccine products based on its proprietary virus-like particle platform (VLP) technology. LigoCyte's lead product, the norovirus vaccine, uses VLP technology which enables the production of vaccines designed to cover multiple genetic varieties (or "strains") of norovirus. The vaccine candidate has been shown to confer protection in an initial human challenge trial. Approval for the vaccine will be sought in the United States, Europe and other countries based on disease burden.

"This milestone underscores Takeda's commitment to innovation and the advancement of global public health through the development of novel vaccines," said Tadataka Yamada, M.D., Takeda's chief medical and scientific officer and member of the Takeda board of directors. "Norovirus is responsible for a significant burden of disease around the world and is notoriously difficult to control. With this acquisition, Takeda will help to protect families and communities from this virus."

In recent years, norovirus has become recognized as the most common cause of outbreak and foodborne gastroenteritis in developed countries. Each year, outbreaks are reported on cruise ships, in health care and long-term care facilities and in child care settings, often requiring closure of facilities for cleaning, and resulting in significant disruption of operations and economic consequences. According to the Centers for Disease Control and Prevention, norovirus infects 21 million people in the United States each year.

In addition to the norovirus vaccine candidate, LigoCyte has also initiated preclinical development of vaccines against respiratory syncytial virus, influenza and rotavirus.

"LigoCyte is pleased to become a part of a leading research-based global pharmaceutical company with a commitment to vaccines and the resources to develop our pipeline," said Donald P. Beeman, chief executive officer, and member of the LigoCyte board of directors. "Together, we believe we have the right combination of expertise and dedication to bring our norovirus vaccine to market. We look forward to supporting Takeda's vaccine research and development efforts and contributing to the long-term success of Takeda's Vaccine Business Division."

To preserve continuity and build upon LigoCyte's success, Takeda will continue operating LigoCyte in Bozeman, Montana, for the foreseeable future and intends to retain the management team and its employees. Once the acquisition is complete, Mr. Beeman and his management team will become a part of Takeda's Vaccine Business Division. Pending the satisfaction of customary closing conditions, the deal is expected to close in the next several weeks.

Takeda expects the acquisition of LigoCyte will:

LigoCyte has developed core technologies used in a wide range of virus-like particle vaccines. Virus-like particles, or VLPs, mimic the external protein structure of a virus without including the genetic material (DNA or RNA) necessary for viral replication. The human immune system responds to a VLP vaccine as if it is encountering the live virus, which allows the body to build immune defenses capable of fighting infections. Without genetic material, VLP vaccines are incapable of causing infections themselves while at the same time presenting viral antigens in the most authentic configuration possible.

LigoCyte is a private, clinical-stage biopharmaceutical company focused on developing novel vaccines for gastrointestinal and respiratory indications. LigoCyte's expertise in virus-like particle technology supports a pipeline of enhanced product candidates, including vaccines against norovirus, influenza, respiratory syncytial virus and rotavirus. LigoCyte has funded its product development efforts through a mix of private investment as well as grants and contracts administered through the National Institutes of Health and the U.S. Department of Defense.
