Key result

Oral administration of cHPMPC delayed the onset of clinical signs and significantly reduced viral titres in blood and tissues of pigs infected with African swine fever virus.

Why the study?

African swine fever virus causes severe haemorrhagic disease with high fatality, and no vaccine is widely available.

Does cHPMPC inhibit African swine fever virus replication in vitro and in vivo?

Population

Primary porcine macrophages and pigs infected with African swine fever virus

Comparison

cHPMPC administration vs untreated or timing of addition

Design

In vitro and in vivo study

Implication

Hypothesis-generating for oral cHPMPC in ASFV; larger trials needed before veterinary or outbreak use.

Structured PICO

Does cHPMPC inhibit African swine fever virus replication in vitro and in vivo?

P
Population
Primary porcine macrophages and pigs infected with African swine fever virus (ASFV)
I
Intervention
Cyclic cidofovir (cHPMPC) administered in vitro and orally in vivo
O
Outcome
Inhibition of ASFV replication and late gene expression (in vitro); onset of clinical signs and viral titres in blood and tissues (in vivo)surrogate

cHPMPC demonstrates promising antiviral activity against African swine fever virus in vitro and in vivo, suggesting potential for further development to control outbreaks.

Cite This Study

Goulding et al. (2022) studied African swine fever virus (ASFV) infection. cyclic cidofovir (cHPMPC) was evaluated on Onset of clinical signs and viral titres in blood and tissues. Oral administration of cHPMPC delayed the onset of clinical signs and significantly reduced viral titres in blood and tissues of pigs infected with African swine fever virus.
