Recombinant polyclonal drug trial for HBV gets FDA green light

Drug Discovery World

The US Food and Drug Administration (FDA) has cleared GigaGen’s application to initiate a Phase I trial of its polyclonal drug for the treatment of hepatitis B virus (HBV) infection, GIGA-2339. In mouse models, GIGA-2339 neutralised and cleared HBV’s viral DNA along with its antigens.

Day Zero Antivirals for Future Pandemics

Codon

Brian Wang (co-founder of the nonprofit Panoplia Laboratories ) outlines his approach to making broad-spectrum antivirals. When COVID-19 emerged in 2019, by contrast, mRNA vaccines developed by Pfizer and Moderna took just 326 days from the initial sequencing of the virus to gaining approval for emergency use.

Improving viral vector safety for gene therapies

Drug Discovery World

While many different modalities of delivery vectors exist, the two most common viral vectors are lentivirus and adeno-associated virus. Following initial viral vector transduction, treated samples, typically whole blood and/or enriched cell populations, are collected and the genomic DNA is isolated. The enriched DNA is then sequenced.

Evolved prime editors are smaller and more efficient for therapeutic applications

Broad Institute

Now researchers at the Broad Institute of MIT and Harvard have used cutting-edge continuous laboratory evolution and engineering methods to develop improved versions of the gene-editing tool. Reverse transcriptase proteins that copy RNA templates into strands of DNA are found naturally in all plant and animal cells and in many viruses.

SARS-CoV-2: advancing the production of the ACE2 protein

Drug Target Review

Researchers from Columbia University and the US Department of Energy (DOE)’s Brookhaven National Laboratory have elucidated a method to produce large quantities of the receptor that the SARS-CoV-2 spike protein uses to bind to the surface of human cells.

Phages could help to tackle antimicrobial resistance

Drug Target Review

Researchers from the Laboratory of Bacteriology at The Rockefeller University have now found that bacteria sense phages by a defensive response named CBASS (cyclic oligonucleotide-based antiphage signalling system) which detects viral RNA. Its presence elsewhere would indicate something is wrong. But what, exactly?”
