Partnership of non-profits, pharmaceutical companies could yield major health, economic impacts worldwide                                                                                                     

WASHINGTON, D.C. — September 16, 2014 — The Sabin Vaccine Institute (Sabin) today announced that its product development partnership (Sabin PDP) received $2 million from the Global Health Innovative Technology Fund (GHIT Fund) to develop a new therapeutic vaccine formulation for Chagas disease. Baylor College of Medicine, Eisai Co., Ltd. (Eisai) and Aeras are partnering on this project with the Sabin PDP, based at the Sabin Vaccine Institute and Texas Children’s Hospital Center for Vaccine Development in Houston, Texas.

“New tools for Chagas disease are desperately needed, especially ones that are safe and effective for pregnant women and children. We are eager to begin working towards a successful, cost-effective therapeutic vaccine, a tool that offers tremendous promise for saving lives and treating all vulnerable populations,” said Peter Hotez, MD, PhD, president of Sabin, director of the Sabin Vaccine Institute and Texas Children’s Hospital Center for Vaccine Development and dean of the National School of Tropical Medicine at Baylor College of Medicine. “An achievement of this kind could also transform the entire field of vaccinology for neglected tropical diseases (NTDs) and help address several Millennium Development Goals (MDGs).”

This two-year preclinical study will use a favorable protein-based antigen (Tc24) formulated with a novel TLR4 agonist adjuvant (E6020) developed by Eisai to elicit a stronger and more effective immune response compared to conventional aluminum-based adjuvant formulations. Protein-based vaccines are best positioned for clinical translation because of their excellent safety record, history of advancing to licensure and ability to produce protective immunity in humans.

“Eisai is pleased to contribute with formulation expertise and with the vaccine adjuvant E6020 to this important initiative as part of its existing collaboration with the Sabin PDP to reduce the widespread suffering caused by Chagas disease,” said Takashi Owa, PhD, chief innovation officer of Eisai. “As an original signatory to the 2012 London Declaration on NTDs, Eisai is a committed partner in the fight against NTDs and seeks to expand access among the world’s poorest people to essential, life-saving interventions.”

The Sabin Vaccine Institute and Texas Children’s Hospital Center for Vaccine Development, led by faculty at Baylor College of Medicine, will lead on process development optimization and scale up, and on formulation and characterization studies, including preclinical evaluation for the selected vaccine targets. Aeras’ manufacturing unit will reproduce the technology and process development and scale-up activities for the partnership.

Ultimately, a therapeutic vaccine could solve current challenges of drugs used to combat Chagas disease, including high toxicities, prolonged treatment regimens, low efficacy in preventing severe cardiac complications and contraindication in pregnancy.

“We are proud to help pave the way for urgently needed vaccines and drugs that could potentially save hundreds of thousands of lives,” said BT Slingsby, MD, PhD, MPH, CEO and executive director of the GHIT Fund. “These exciting technologies are great advances that could be game-changers for diseases that claim too many lives and keep vast areas of our world in poor health and poverty.”

Chagas disease is an NTD estimated to infect 7.5 million people and cause more than seven billion dollars in annual economic losses globally. Chronic Chagas cardiomyopathy, present in approximately 30 percent of those infected with Chagas disease, causes arrhythmias, aneurysms, heart failure and sudden death. The T. cruzi parasite, which causes Chagas disease, is present in approximately 11 percent of pregnant women in Latin America and 40,000 women in North America and Japan at any given time, and between five to 10 percent of those pregnant women pass the infection to their unborn fetus.


Chagas disease is predominantly found in North America and Europe, but a few thousand cases have appeared in Japan. In the Latin America region, based on disability adjusted life years (DALYs), the burden of Chagas disease is five times greater than malaria.
