RESEARCH TRIANGLE PARK, NC, USA I December 15, 2014 I BioCryst Pharmaceuticals, Inc. (BCRX) today announced the dosing of the first subject in a randomized, placebo-controlled Phase 1 clinical trial to evaluate intramuscular (I.M.) administration of BCX4430 in healthy volunteers. BCX4430 is being developed as a potential treatment for hemorrhagic fever viruses, including Ebola virus and Marburg virus disease.

The main goals of this first-in-human study are to evaluate the safety, tolerability and pharmacokinetics of escalating doses of BCX4430 administered via I.M. injection in healthy subjects. In part one of the study, subjects will receive a single dose of BCX4430; in part two of the study, subjects will receive BCX4430 for seven days. Up to six single-dose cohorts and four multiple-dose cohorts will be evaluated, with a total of up to 88 volunteers participating. Study details are available on www.clinicaltrials.gov.

This project is funded 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.
