Ebola Treatment Breakthrough: Preliminary Testing Reveals 100% Survival Rate in Monkeys for a Novel Drug
A Potential Breakthrough in Combating Deadly Ebola Virus
Get ready for a possible game-changer in the fight against one of the world's deadliest infectious diseases. Researchers at the University of Texas Medical Branch (UTMB) have discovered that a single dose of an experimental pill, obeldesivir, could significantly lower the mortality rate of Ebola in non-human primates.
This groundbreaking study was published in Science Advances on a Friday, with UTMB leading the charge. The oral antiviral drug, obeldesivir, managed to prevent 100% of deaths in Ebola-exposed monkeys, offering hope for a more effective measure against Ebola and similar viruses.
Ebola: A Deadly Menace
Ebola is a zoonotic disease, mainly transmitted to humans through contact with infected animals like African fruit bats. It can also spread among people via close proximity to bodily fluids, including blood and semen. Although Ebola's rapid progression and high mortality typically limits its transmission, large-scale outbreaks have been documented, causing severe health crises. For example, during 2014-2016, a Zaire ebolavirus outbreak in West Africa infected nearly 30,000 people and killed more than 11,000.
Obeldesivir: A Promising Solution
Obeldesivir, an oral version of the antiviral remdesivir, was developed initially to combat COVID-19. In their new study, UTMB researchers provided obeldesivir to cynomolgus and rhesus macaques after they had received a lethal dose of the Zaire ebolavirus. Remarkably, 100% of rhesus macaques and 80% of cynomolgus macaques treated with obeldesivir survived their infections. The treatment impeded the virus's ability to replicate and boosted the monkeys' immune response to it.
Previous research by the team has already suggested that obeldesivir may be effective against other Ebola species, such as Sudan virus. In early January, the researchers also discovered that obeldesivir could shield monkeys from Marburg, another deadly virus closely related to Ebola, during a recent Tanzania outbreak.
Although human trials are necessary to confirm obeldesivir's potential, the UTMB researchers are optimistic that the drug could become a widely applicable and user-friendly weapon against these deadly infections.
"For outbreak response, oral antivirals might present substantial advantages over now-approved intravenous drugs, such as easy supply, storage, distribution, and administration," they wrote in their paper.
Key Insights
