VIR-7813, created by GSK and Vir Biotechnology, is a new treatment for those with mild to moderate illness. However, a trial using the drug on very sick patients was halted last week due to a lack of benefit.
It contains monoclonal antibodies — laboratory-produced molecules that mimic human antibodies.
Due to its success, the global phase 3 clinical trial was stopped early with plans to immediately seek an emergency use authorisation in the United States and approval in other countries, including potentially the UK.
The drug works by blocking the virus from healthy cells and clearing infected cells, and is designed to be given as a single intravenous (IV) infusion.
VIR-7831 has also been found to be effective against the most common current Covid-19 variants, including the Kent, South African and Brazilian variants, in a separate study.
Dr Hal Barron, chief scientific officer at GSK, said: “We are pleased that this unique monoclonal antibody was able to bring such a profound benefit to patients.

Among the total number of deaths caused by different types of cancer, esophageal cancer is the sixth most significant. Several conventional treatments, such as radiotherapy, chemotherapy, and surgery have multiple side effects, including off-target [...]
Cell membrane-coated nanoparticles, applied in targeted drug delivery strategies, combine the intrinsic advantages of synthetic nanoparticles and cell membranes. Although stem cell-based delivery systems were highlighted for their targeting capability in tumor therapy, inappropriate [...]
When babies in the African countries of Guinea Bissau and Uganda were given the tuberculosis vaccine, something remarkable happened. Instead of the vaccine only protecting against the target bacteria – Myocbacterium tuberculosis – the tuberculosis vaccine offered broad protection against a [...]
Thousands of years ago, across the Eastern Mediterranean, multiple Bronze Age civilizations took a distinct turn for the worse at around the same time. The Old Kingdom of Egypt and the Akkadian Empire both collapsed, and there was [...]

Self-healable ionic sensing materials with fatigue resistance are imperative in robotics and soft electronics for extended service life. The existing artificial ionic skins with self-healing capacity were prepared by network reconfiguration, constituting low-energy amorphous [...]
As demand for solar energy rises around the world, scientists are working to improve the performance of solar devices—important if the technology is to compete with traditional fuels. But researchers face theoretical limits on [...]
When shrimp shell nanoparticles were mixed into cement paste, the material became substantially stronger — researchers propose an innovation that could lead to less seafood waste and fewer carbon dioxide emissions from concrete production. [...]
A black-and-white video shared on social media showed a microscopic corkscrew-shaped helix as it appeared to consume a sperm, transport it, and ultimately lead the little swimmer into the wall of an [...]
Polymers containing quantum dots (QDs) are considered crucial components of next-generation consumer items, but ambiguity remains regarding how these compounds may negatively affect public health and the environment. A pre-proof paper from the Journal of Hazardous [...]

Although retinoic acid (RA) can induce cell death, its weak anticancer efficacy limits its clinical applications. To this end, stimulus-responsive self-assembling prodrug-based nanomedicines are promising candidates that enable controlled drug delivery. In an article [...]
Graphene is a multifunctional carbon nanomaterial widely synthesized for its applications in composites, energy storage, and sensors. Although previous reviews mentioned that achieving an increased yield compromises graphene quality, limiting its commercialization, recent research [...]
