West Nile Virus Trials

JAMA. 2004;292(8):916. doi:10.1001/jama.292.8.916-d

The National Institute of Allergy and Infectious Diseases is expanding its clinical trial of an experimental West Nile virus (WNV) treatment. The trial opened at 36 sites last September, and it is expected to add about 24 new sites this summer.

The trial is assessing the safety of a product containing WNV antibodies derived from individuals who have high blood levels of these antibodies. These antibodies may have the potential to help patients fight WNV infections.
