A new gene editing method uses the CRISPR technique to modify the cells of an organ in vivo, creating a mosaic used to identify the effects of each altered gene. Scientists from the Swiss Federal Institute of Technology (ETH) in Zürich developed this technology called AAV-Perturb-seq, based on adeno-associated virus (AAV) to target, edit and analyze single-cell genetic perturbations.
The rapid migration of gene editing technologies from the bench to the clinic has opened up new therapeutic possibilities for patients with previously intractable genetic diseases and difficult-to-treat cancers. But mobilizing gene editing components into a target cell or organ remains a critical step for the field. Integra Therapeutics SL, an early stage Spanish firm, is now engaged in that process with a novel gene writing platform.
Chronic hepatitis B affects around 250 million people in the world and its cure remains elusive. At the 2023 European Association for the Study of the Liver Congress in Vienna, Austria, Emily Harrison of Precision Biosciences Inc. presented the company’s work on using a naturally occurring endonuclease in the development of its ARCUS gene editing approach to eradicating the persistent viral infection.
With CRISPR-Cas9 technology making its way toward clinical practice, laboratories are studying different gene-editing techniques, from base editors to prime editors, to correct mutations associated with various pathologies. Researchers at Tessera Therapeutics Inc. have been inspired by retrotransposons to develop a tool for editing DNA using RNA and reverse diseases such as phenylketonuria (PKU) or sickle cell disease (SCD).
Verve Therapeutics Inc. has entered into an exclusive research collaboration with Eli Lilly and Co. focused on advancing Verve’s preclinical stage in vivo gene editing program targeting lipoprotein(a) (Lp[a]), a risk factor for atherosclerotic cardiovascular disease (ASCVD), ischemic stroke, thrombosis and aortic stenosis.
Promising early data continue to roll out for Intellia Therapeutics Inc.’s hereditary angioedema (HAE) candidate, NTLA-2002, with one of the earliest treated patients in the phase I study remaining attack-free for more than a year. But it was the systemic CRISPR candidate’s potential as a one-time treatment that generated the most discussion on the company’s call as investors tried to assess its potential advantage in a crowded HAE market.
In its bid to become, as Chairman and CEO David Hallal said, the “world’s most indispensable cell and gene therapy technology company,” Elevatebio LLC disclosed a $401 million series D round with support from new and existing investors. At the same time, the company’s Life Edit Therapeutics Inc. affiliate inked a potential billion-dollar collaboration focused on gene editing therapies.
Scribe Therapeutics Inc. is selling exclusive rights to its CRISPR-based technology to Prevail Therapeutics Inc. for a figure that could top $1.6 billion as the firms team up to develop genetic therapies for serious neurological and neuromuscular diseases.
A research initiative led by Jennifer Doudna and Jill Banfield of the Innovative Genomics Institute at the University of California, Berkeley, has landed $70 million in funding from the Audacious Project to bring the power and precision of CRISPR-based genome editing to the gut microbiome of humans and animals, in an ambitious effort to engineer complex microbial communities to achieve outcomes that can benefit human health and the environment.
Seamless Therapeutics GmbH raised $12.5 million in seed financing to take forward a novel gene editing technology based on reprogramming recombinase enzymes.
