BioCryst Receives Additional NIAID Funding to Conduct a Non-Human Primate Study of BCX4430 in Ebola Virus Disease

RESEARCH TRIANGLE PARK, N.C., Aug. 29, 2014 (GLOBE NEWSWIRE) -- BioCryst Pharmaceuticals, Inc. (BCRX) today announced that the National Institute of Allergy and Infectious Diseases (NIAID) has awarded a contract modification for an additional $2.4 million to BioCryst to conduct a dose ranging efficacy study of an intramuscular formulation of BCX4430 in non-human primates as a treatment for Ebola virus disease. The study is expected to be initiated within weeks.

The successful completion of an efficacy study in an experimental Ebola virus disease model in non-human primates represents an important next step towards understanding the potential of BCX4430 as a treatment for Ebola disease in humans. NIAID, part of the National Institutes of Health, granted a contract to BioCryst in September 2013 valued up to $22.0 million over five years. With this additional award, the BCX4430 development contract has been increased in value to $24.4 million, if all options are exercised.

This project will be funded in whole or in part with Federal funds from the National Institute of Allergy and Infectious Diseases, National Institutes of Health, Department of Health and Human Services, under Contract No. HHSN272201300017C.
