The study examined the vaccine's safety, immunogenicity, and in vitro efficacy against arboviral (any group of viruses transmitted by mosquitoes, ticks, etc.) diseases. These include malaria, dengue, yellow fever, the zika virus, West Nile virus, chikungunya virus, and dengue.
Open Orphan said the vaccine generated a strong immune response in participants while demonstrating that AGS-v PLUS was well tolerated with no serious adverse events experienced.Â
“AGS-v PLUS showed a more robust immune response compared to AGS-v, a first-generation vaccine candidate developed by Imutex,” said Open Orphan.
Cathal Friel, Executive Chairman of Open Orphan, said: “The positive data for the AGS-v PLUS mosquito vaccine candidate is encouraging; data showed AGS-v PLUS was well tolerated and generated a strong immune response in participants against mosquito-borne diseases, with an increased immune response compared to the four peptide AGS-v candidate.Â
“Imutex's AGS-v and AGS-v PLUS vaccine candidates both employ a novel proposed dual action mechanism that prevents infection in humans whilst controlling mosquito population by limiting transmission.”
Shares of Open Orphan are currently up 1.16% at 19.98p after initially hitting a high of 21p.Â
