BCX4430 (Immucillin-A) is an antiviral drug, an adenosine analog (a type of nucleoside analog). It is developed by BioCryst Pharmaceuticals with funding from NIAID, originally intended as a treatment for Hepatitis C, but subsequently developed as a potential treatment for deadly filovirus infections such as Ebola virus disease and Marburg virus disease. It also shows broad-spectrum antiviral effectiveness against a range of other RNA virus families, including bunyaviruses, arenaviruses, paramyxoviruses, coronaviruses and flaviviruses. BCX4430 has been demonstrated to protect against both Ebola and Marburg viruses in both rodents and monkeys, even when administered up to 48 hours after infection, and development for use in humans is being fast-tracked due to concerns about the lack of treatment options for the 2013-2016 Ebola virus epidemic in West Africa. BCX4430 also showed efficacy against Zika virus in a mouse model, though there are no plans for human trials at this stage.
