IAVI recently announced the start of a first-in-human clinical trial evaluating a combination injection of four broadly neutralizing antibodies, with the aim of eventually developing a tool to prevent HIV transmission in infants during the postnatal period. The combination shot includes four antibodies that target different HIV receptors, including IAVI’s broadly neutralizing antibody ePGT121v1-LS. The current trial is evaluating safety, dosing, pharmacokinetics, durability, and efficacy in 118 adult participants across the United States and Peru, and, if successful, could pave the way for future studies in infants.
A research team has identified a bacterium strongly associated with noma, a potentially fatal infection for which the underlying cause is poorly understood. The researchers used metagenomic sequencing and machine learning algorithms to analyze saliva samples from children with acute noma. They identified a bacterial species that may be responsible for the disease, which was detected in the early stages of infection and does not carry known antibiotic resistance genes, suggesting that infection could be effectively treated with existing antibiotics if detected early enough. These findings also pave the way for the development of diagnostic tools that can detect noma early on, when treatment is most effective and before irreversible damage has been done.
Last week, Butterfly Network shared that it received regulatory clearance from the US Food and Drug Administration for its artificial intelligence (AI)-powered ultrasound, offering a critical new tool to improve maternal care in low-resource settings with limited access to prenatal imaging. Compared to traditional ultrasounds that rely on expensive technology, the new device is more affordable and provides results in less than two minutes with fewer inputs. The tool has already been deployed in Malawi and Uganda, and this latest approval will enable its widespread rollout in the United States.
