Emulate Inc. has launched a new adeno-associated virus (AAV) transduction application for the Liver-Chip that enables gene therapy researchers to test the delivery efficiency and safety of AAV vectors in a validated, human-relevant model of the liver and get results in weeks.

The first gene therapy to treat severe hemophilia A was among the drugs recommended for European approval by regulators from the EMA’s CHMP at its monthly meeting. Manufactured by Biomarin Pharmaceutical Inc., Roctavian (valoctocogene roxaparvovec) was recommended for conditional marketing authorization in the EU for severe hemophilia A in adults who do not have factor VIII inhibitors and no antibodies to adeno-associated virus serotype 5.

Biotechs that tackle the effects of aging are beginning to make headlines: in January Altos Labs Inc. launched with a reported investment from Jeff Bezos. With Bezos getting involved with San Francisco-based Altos, the immediate reaction was that anti-aging biotechs would be there for the benefit of billionaires searching for eternal life. Not so, according to London U.K.-based Genflow Biosciences plc, which hopes to show that fighting aging is really about improving health as people age.

Combining Sarepta Therapeutics Inc.’s gene editing technology and Genedit Inc.’s Nanogalaxy platform to treat neuromuscular disorders shows promising potential, the companies reported. A year into the research collaboration, Genedit’s polymer nanoparticles have demonstrated the ability to deliver therapeutic cargo to specific muscle tissue following system administration of targeted genetic medicines.

Attempts to modernize the conceptual framework of brain function and dysfunction are one prerequisite for brain disorders to benefit from precision medicine. For the circuit-based insights that are slowly emerging to benefit patients, though, better targeting methods are needed.

A multidisciplinary team of scientists led by Britt Adamson at Princeton University along with collaborators from the Massachusetts Institute of Technology, the genome editing company Editas Medicine, and University of California, San Francisco have developed a novel high-throughput screening tool, Repair-seq, to profile mutations at targeted DNA lesions.

Researchers at Oregon Health and Science University have used mouse models to estimate the frequency at which gene therapies delivered by adeno-associated virus (AAV) vectors integrated into host DNA, and come up with an estimate of up to roughly 3% – a number that is orders of magnitude higher than previous estimates and would translate into several hundred million cells with integrated viral vectors in an adult liver, assuming that 10% of cells took up the transgene.

For most people, neither polyglutamine disorders nor neuromuscular disorders are likely to be among the things they associate with androgen receptor (AR) dysfunction. But the three are indeed linked. And researchers have reported new insights into the nature of those links that could lead to a treatment for spinal and bulbar muscular atrophy, and possibly other disorders linked to AR signaling dysfunction.

In one of the biggest collaboration deals of the year, Shape Therapeutics Inc. entered a collaboration and license agreement with Roche Holding AG to develop gene therapies for targets in areas that include Alzheimer’s disease, Parkinson’s disease and rare diseases. Seattle-based Shape is eligible to receive an initial payment, development, regulatory and sales milestone payments that could exceed $3 billion in aggregate value.
