ClearPath Development Launches Second Vaccine Company Under Strategic Partnership With Astellas

Establishes Nosocomial Vaccine Corporation (NVC) and Initiates Research Collaboration with Affinivax and the University of Maryland School of Medicine

ROCKVILLE, Md. and BALTIMORE and CAMBRIDGE, Mass., Oct. 26, 2015 /PRNewswire-USNewswire/ -- ClearPath Development Company (ClearPath) announced today the launch of its second vaccine company, NVC (Nosocomial Vaccine Corporation), with the support of its partner, Astellas Pharma Inc.  The partnership between ClearPath and Astellas was established to support the goal of building a global vaccine franchise and launched its first company, RSV Corporation (RSVC), in December 2013.  NVC has initiated research collaborations with two partners to develop a nosocomial vaccine; Affinivax Inc. (Cambridge, Mass.); and the Center for Vaccine Development at the University of Maryland School of Medicine (Baltimore).  The research collaboration will utilize Affinivax's proprietary vaccine platform, Multiple Antigen Presentation System (MAPS), to develop vaccines that prevent bacterial nosocomial infections, also referred to as healthcare-associated infections (HAIs).

"Together with our collaborators at Affinivax and the University of Maryland School of Medicine, we are accelerating research and development of a vaccine for important pathogens causing nosocomial infections, one of the most common HAIs," said Donna Ambrosino, M.D., CEO, NVC.  "HAIs are a significant global health concern, with the Centers for Disease Control and Prevention estimating that more than 1.9 million patients per year in the United States will contract a bacterial nosocomial infection in medical facilities, including ambulatory surgical centers, hospice centers, nursing homes and rehabilitation centers."

HAIs acquired in acute or chronic care medical facilities represent a major public health burden.  According to JAMA Internal Medicine, HAIs cost $9.8 billion annually in the United States alone.  With up to 4 percent of patients becoming infected, the added morbidity and mortality is significant as bacterial nosocomial infections are highly resistant to available antibiotic therapies.  Currently, there is no vaccine available for any of the major nosocomial pathogens including organisms that are responsible for the majority of highly antibiotic resistant bacteria, which have now been recognized as a significant public health threat.

"This is an important area of unmet medical need," said George Siber, CSO, ClearPath Development Company. "We are excited to launch this research program in partnership with Astellas Pharma and a team of research collaborators who are well-suited to create candidate vaccines which can address this growing public health threat.  We look forward to moving quickly into pre-clinical studies."

Dr. George Siber and Dr. Donna Ambrosino, both recognized vaccine experts with more than 35 years of experience, are leading the NVC development team.  From 1996 to 2007, Dr. Siber was Executive Vice President and Chief Scientific Officer of Wyeth Vaccines Research where he oversaw the approval and marketing of six childhood vaccines including Prevnar, Meningitec, Rotashield and FluMist.  Dr. Ambrosino from 1998 through 2011 was CEO of MassBiologics where she oversaw the development of monoclonal antibody products including Rabies Mab, now in Phase 3, and a C. difficile product  (Bezlotoxumab) that will be submitted for approval by Merck in 2015.

The team at the Center for Vaccine Development will be led by Dr. Alan S. Cross, M.D., professor of medicine at the University of Maryland School of Medicine, as well as a world-renowned expert in Gram negative bacteria research and vaccine development. Dr. Rick Malley will lead the Affinivax team, a well-recognized expert in infectious diseases, vaccine development, and a co-inventor of the Multiple Antigen-Presenting System (MAPS) platform technology, which represents a highly innovative approach for creating novel vaccine formulations that may provide broad protection against the most challenging pathogens.
