Galidesivir (BCX4430 , immucillin-A ) is an antiviral drug , an adenosine analog [ 1] nucleoside analog ).[ 2] 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 , as well as Zika virus .[ 3] phase 1 human trial in Brazil for coronavirus .[ 4]
It also shows broad-spectrum antiviral effectiveness against a range of other RNA virus families, including bunyaviruses , arenaviruses , paramyxoviruses , coronaviruses , flaviviruses , and phleboviruses .[ 5] [ 1] Ebola virus epidemic in West Africa .[ 6]
Galidesivir later showed efficacy against Zika virus in a mouse model.[ 7]
Galidesivir abrogates viremia in Zika virus–infected rhesus Macaques.[ 8]
Galidesivir is one of several antiviral drugs being tested for coronavirus disease 2019 .[ 9]
On April 9, 2020, BioCryst opened enrollment into a randomized, double-blind, placebo -controlled clinical trial to assess the safety, clinical impact and antiviral effects of galidesivir in patients with COVID-19 .[ 4]
