Leading Ebola researcher at UTMB says there's an effective treatment for Ebola
Date:8/29/2014

A leading U.S. Ebola researcher from the University of Texas Medical Branch at Galveston has gone on record stating that a blend of three monoclonal antibodies can completely protect monkeys against a lethal dose of Ebola virus up to 5 days after infection, at a time when the disease is severe.

Thomas Geisbert, professor of microbiology and immunology, has written an editorial for Nature discussing advances in Ebola treatment research. The filoviruses known as Ebola virus and Marburg virus are among the most deadly of pathogens, with fatality rates of up to 90 percent.

Since the discovery of Ebola in 1976, researchers have been actively working on treatments to combat infection. Studies over the past decade have uncovered three treatments that offer partial protection for monkeys against Ebola when given within an hour of virus exposure. One of these treatments, a VSV-based vaccine was used in 2009 to treat a laboratory worker in Germany shortly after she was accidentally stuck with a needle possibly contaminated by an Ebola-infected animal.

Further advances have been made that can completely protect monkeys against Ebola using small 'interfering' RNAs and various combinations of antibodies. But these treatments need to be given within two days of Ebola exposure.

"So although these approaches are highly important and can be used to treat known exposures, the need for treatments that can protect at later times after infection was paramount," said Geisbert.

Further research led to a cocktail of monoclonal antibodies that protected 43% of monkeys when given as late as five days after Ebola exposure, at a time when the clinical signs of the disease are showing.

The new study from Qui and colleagues at MAPP Biopharmaceutical Inc. used ZMAPP to treat monkeys given a lethal dose of Ebola. All of the animals survived and did not show any evidence of the virus in their systems 21 days after infection, eve
