Vanderbilt University researchers have joined a multi-center effort led by Pennsylvania-based Inovio Pharmaceuticals Inc. to accelerate development of potential antibody therapies against the often-lethal Ebola virus.
On Wednesday, Inovio announced it had been awarded an initial two-year, $21-million grant from the Defense Advanced Research Projects Agency (DARPA), part of the U.S. Department of Defense, to support the project. Vanderbilt’s share of the grant is $1.3 million.
James Crowe Jr., MD, and his colleagues will provide human monoclonal antibodies they’ve generated against the virus to Inovio Pharmaceuticals for further development.
A team led by Kathryn Edwards, M., the Sarah H. Sell and Cornelius Vanderbilt Professor of Pediatrics and director of the Vanderbilt Vaccine Research Program, will test the potential treatments for safety and efficacy in clinical trials.
“This major emergency financial commitment from the U.S. government allows us to pursue very rapid testing of new Ebola antibody treatments that we have been developing over the last few months,” says Crowe, the Ann Scott Carell Professor and director of the Vanderbilt Vaccine Center.
“The speed with which we’ll be able to transition from drug discovery to clinical trials is really unprecedented,” he adds.
The antibodies under development at Vanderbilt are not vaccines, which stimulate the body’s own immune defenses against infectious diseases. Rather, injectable antibodies are treatments. Like heat-seeking missiles, they seek out and destroy their targets, in this case, the Ebola virus.
They are meant to provide short-term protection to health care workers and others at risk of exposure. They also could be used as antiviral drugs to treat patients who are already infected with Ebola virus.
Ebola has killed more than 10,000 people in West Africa in the past 12 months.
Crowe and his colleagues have developed a method for quickly generating large quantities of human antibodies against specific viral targets. The specific, “monoclonal” antibodies are generated by clones of a type of white blood cell that have been fused to myeloma (cancer) cells to form fast-growing “hybridomas.”
“We’re the only lab in the world that has a high-efficiency human hybridoma technique for isolating human monoclonal antibodies,” he says.
The Inovio-led project is pursuing both a DNA-based and protein-based monoclonal antibody product as well as a potential DNA-based vaccine against Ebola virus infection.
Other collaborators include MedImmune, the global biologics research and development arm of AstraZeneca; GeneOne Life Sciences and its manufacturing subsidiary, VGXI, Inc.; David Weiner, PhD, and colleagues at the University of Pennsylvania’s Perelman School of Medicine; the Public Health Agency of Canada; and Emory University.

Beyond the Surface: Rethinking Environmental Hygiene Validation at Exchange25
June 30th 2025Environmental hygiene is about more than just shiny surfaces. At Exchange25, infection prevention experts urged the field to look deeper, rethink blame, and validate cleaning efforts across the entire care environment, not just EVS tasks.
A Controversial Reboot: New Vaccine Panel Faces Scrutiny, Support, and Sharp Divides
June 26th 2025As the newly appointed Advisory Committee on Immunization Practices (ACIP) met for the first time under sweeping changes by HHS Secretary Robert F. Kennedy Jr, the national spotlight turned to the panel’s legitimacy, vaccine guidance, and whether science or ideology would steer public health policy in a polarized era.
Getting Down and Dirty With PPE: Presentations at HSPA by Jill Holdsworth and Katie Belski
June 26th 2025In the heart of the hospital, decontamination technicians tackle one of health care’s dirtiest—and most vital—jobs. At HSPA 2025, 6 packed workshops led by experts Jill Holdsworth and Katie Belski spotlighted the crucial, often-overlooked art of PPE removal. The message was clear: proper doffing saves lives, starting with your own.
