A World Health Organization (WHO) panel on Thursday recommended the use of two additional drugs, baricitinib and sotrovimab, for COVID-19 patients. Baricitinib, developed by Eli Lilly and sold under the brand name Olumiant, was recommended in combination with corticosteroids for patients with severe COVID-19. WHO experts cited evidence indicating that baricitinib—an oral drug also used to treat rheumatoid arthritis—improves survival rate and reduces the need for ventilation, with no observed increase in adverse effects. Sotrovimab, a monoclonal antibody therapy developed by GlaxoSmithKline (GSK) and Vir Biotechnology, was conditionally endorsed for non-severe patients at the highest risk of hospitalization. Studies on the effectiveness of monoclonal antibodies against the omicron variant are ongoing, though the GSK-Vir treatment has been shown to retain its activity in initial lab tests.

An mRNA-based HIV vaccine candidate developed at the National Institute of Allergy and Infectious Diseases (NIAID) showed promise in preclinical studies, new research shows. The experimental vaccine works by delivering instructions for making two key HIV proteins, which are then assembled into virus-like particles that induce immune responses similar to natural HIV infection. NIAID tested the vaccine in mice and rhesus macaques, results of which showed the injections were well-tolerated and elicited immune responses against an HIV-like virus. The research team plans to conduct a phase 1 trial of the novel mRNA HIV vaccine in healthy adult volunteers after further refinement and testing.

Researchers at UCLA have made progress in efforts to develop a cure for HIV by targeting infected cells that could be lying dormant in the body, according to a study published in Nature Communications last week. In the new study, researchers built upon a method originally developed in 2017 to kill hidden HIV-infected cells using cells that are naturally produced by the body’s immune system. The study used the “kick and kill” strategy, with researchers first administering a compound to flush out hidden HIV-infected cells, then injecting natural killer cells into a mice’s bloodstream. This cleared HIV completely in 40 percent of infected mice, showing proof of concept for a therapeutic approach to potentially eliminate HIV from the body. Researchers say they now hope to develop an approach that eliminates HIV in 100 percent of tested mice via further experiments and move toward preclinical studies.
