Antiviral developer Chimerix shares fell 7 percent Thursday after the Durham company reported a wider loss in the second quarter.
Chimerix said Thursday its net loss more than doubled to $24.8 million from $11.7 million a year ago as the company ramped up spending on drug research.
At the same time, second-quarter revenues surged to $4.1 million from $919,000 due to an increase of research funding from the federal Biomedical Advanced Research and development Authority. BARDA is funding research to develop a treatment for the national stockpile against a potential bioterror smallpox attack.
Chimerix also said its research and development expenses rose to $21.8 million from $8.1 million.
