Engineered virus-like particles for transient delivery of prime editor ribonucleoprotein complexes in vivo. By Sarah C.P.
To be effective, these therapies must deliver the new genes, or the gene-editing machinery, to enough of the right cells in the body to have a therapeutic effect. But researchers have struggled to design molecular vehicles that can deliver gene-based therapies safely and effectively to the right cells.
Viral vectors have been crucial in transforming the gene therapy landscape due to their natural ability to infect cells. 1 In 2017, the US Food and Drug Administration (FDA) approved the first AAV-based gene replacement therapy (Luxturna), for Leber congenital amaurosis type 2.
Adeno-associated virus (AAV) is a single stranded, Parvoviridae DNA virus, packaged in a non-enveloped icosahedral capsid, that can be used to express genes of interest in cell and animal models. This post was contributed by guest blogger Didem Goz Ayturk with edits and updates from Addgenies Karen Guerin and Susanna Stroik.
The FDA’s January 2020 guidance, Chemistry, Manufacturing and Control (CMC) [1] Information for Human Gene Therapy Investigational New Drug Applications (INDs), outlines the analytical methods that define the quality, safety and efficacy of gene therapy therapeutics.
The studies are part of a package of 10 papers in Nature that take distinct, yet complementary, approaches to mapping the mouse nervous system at the single-cell level. The package also includes the spatial, single-cell atlas of the mouse brain and spinal cord that was led by Wang and Liu and was first published online in September in Nature.
As the pharma industry stands firm in its commitment to advance the sector to fight Covid-19, news has emerged from the European Commission who intend to streamline the development of therapies using genetically modified organisms to treat Covid-19. Regenerative medicine and advanced therapies thriving despite Covid-19 disruption.
Pfizer has designed its own packaging using dry ice that can be stored for weeks without the specialized freezers. They use mRNA that codes for the spike protein in the SARS-CoV-2 virus, which is embedded in a nanolipid particle—basically a minuscule fat molecule. Both the Pfizer-BioNTech and Moderna vaccines utilize mRNA technology.
In the overall patient group with detectable virus at baseline, the average daily reduction in viral load through day 7 was a 0.36 About REGN-COV2 REGN-COV2 is a combination of two monoclonal antibodies (REGN10933 and REGN10987) and was designed specifically to block infectivity of SARS-CoV-2, the virus that causes COVID-19.
Because its small size simplifies delivery to cells, NovaIscBs developers say it is a promising candidate for developing gene therapies to treat or prevent disease. The engineered protein, called NovaIscB, can be adapted to make precise changes to the genetic code, modulate the activity of specific genes, or carry out other editing tasks.
About casirivimab and imdevimab Casirivimab and imdevimab (formerly known as REGN-COV2 or REGEN-COV2) is a cocktail of two monoclonal antibodies (also known as REGN10933 and REGN10987, respectively) and was designed specifically to block infectivity of SARS-CoV-2, the virus that causes COVID-19. who require oxygen therapy due to COVID-19, OR.
Instead of the black, printed stripes of the Universal Product Codes (UPCs) that we see on everything from package deliveries to clothing tags, they used short, unique snippets of DNA to label cells. A little more than a decade ago, researchers began adapting a familiar commercial concept to genomics: the barcode.
The research is part of an ongoing collaboration between Columbia University and Tonix that focuses on T cell and antibody responses to SARS-CoV-2 (CoV-2), the virus that causes COVID-19. solution), which is in Phase 2 development for the treatment of life-threatening cocaine intoxication and has FDA Breakthrough Therapy designation.
The data used by AgencyIQ is obtained from reports put out by CDER and CBER , as well as approval letters and review packages posted to the Drugs@FDA database. The accompanying press release described the approvals as “a wide range of therapies” that “will help patients and consumers live better and possibly longer lives.”
” In the trial, the 49 patients evaluated had a median of five prior lines of therapy (range: 2-17) with 100% being triple-refractory and 57% being penta-refractory; all patients were refractory to anti-CD38 therapy. With a median follow up of 2.6 Multiple myeloma is not curable despite treatment advances.
Building on previous work by the vector-engineering lab of Ben Deverman at the Broad, the team developed a pair of adeno-associated viruses (AAVs) to package and deliver the base-editing machinery to brain cells. Theres still a long way to go to make this a therapy, Minikel said. But its really exciting to see how much is possible.

If a gene-editing therapy could install an interruption that mimics those that occur naturally in some patients, it might stop the repeat from expanding and halt or slow down disease progression. These individuals are also less likely to pass their disease along to their children than people with uninterrupted repeats.
Tom Ireland writes about the companies and technologies that are reimagining phage therapy. Soon after its publication, scientists, journalists, and investors were revisiting ‘phage therapy’ as a promising alternative to our failing antibiotics. Read it on our website here. Illustration by David S. Fast forward to 2023.
The treatment, now known as Casgevy, became the first CRISPR-based therapy to gain FDA approval, in 2023. If the same virus invades the cell a second time, the gRNA’s spacer sequence will bind to the matching viral DNA sequence, then be cut by the Cas protein.
How does Circio’s circVec technology aim to enhance the potency and reduce the cost of current gold-standard gene therapy? There are three major reasons for why Circio has selected AATD as its lead gene therapy program. Firstly, there have been previous AAV gene therapy clinical studies in this indication that have shown promise.
