NEW YORK--(BUSINESS WIRE)--SIGA Technologies, Inc. (NASDAQ: SIGA) announced today the successful results of two independent primate trials of its smallpox drug SIGA-246. Last month, SIGA announced that SIGA-246 provides complete protection against human smallpox virus in nonhuman primates. The current trials involve infection with high doses of monkeypox virus, which may be lethal in primates if left untreated. SIGA-246 again afforded complete protection against disease symptoms. As with the primate trial last month and the human safety trial announced earlier this year, the current trials also demonstrate that SIGA-246 should be safe as well as effective.
