If we unraveled the DNA of the 46 chromosomes of a single human cell, it would barely measure 2 meters. If we did the same with the rest of the body, if we aligned the 3 billion base pairs of its 5 trillion cells, we could travel the distance from the Earth to the Sun more than 100 times. It seems unreachable. However, that is the unit of knowledge of the large sequencing projects achieved in 2023. From the generation of the human pangenome to cell-by-cell maps of the brain and kidneys, scientists this year have completed several omics collaborative projects stored in large international databases. Now, what’s the plan?

Matinas Biopharma Holdings Inc. has reported results from a series of in vivo studies demonstrating successful oral delivery of two lipid nanocrystal (LNC)-formulated small single-strand oligonucleotides that specifically target the key inflammatory cytokines TNF-α and IL-17A in well-established and validated animal models that mimic acute inflammatory responses seen in human diseases.

Modifying a patient’s DNA is no longer just for science fiction novels. The CRISPR gene editing technique developed by Jennifer Doudna and Emmanuelle Charpentier only took 10 years to reach the market as Casgevy (exagamglogene autotemcel/exa-cel, Vertex Pharmaceuticals Inc.), treating congenital pathologies such as β-thalassemia and severe sickle cell disease (SCD). But science does not stop.

JCR Pharmaceuticals Co. Ltd. has signed a research collaboration, option and license agreement with Alexion, Astrazeneca Rare Disease, part of Astrazeneca plc, for the development of novel oligonucleotide therapeutics with targeted delivery to certain tissues or organs using J-Brain Cargo, JCR’s proprietary blood-brain barrier-penetrating technology.

Scientists at Regeneron Pharmaceuticals Inc. have found a new way to permanently stop allergy through a combination of therapies that prevents the production of antibodies in secondary lymphoid organs and in bone marrow. The approach was tested in vivo in cynomolgus monkeys and in a mouse model.

Although there are different methods of nuclear gene editing, there are still no effective treatments against mitochondrial disorders due to genetic alterations. Now, a group of researchers at Precision Biosciences Inc. and the University of Miami (UM) has developed a genetic edition platform that targets mitochondrial DNA (mtDNA) to delete its mutations.

“The ARCUS technology that we use is based on an enzyme found in nature called I-CreI. It is an enzyme that recognizes a 22 base pair DNA sequence within a species of green algae. And when it finds that DNA sequence, it will generate double-strand breaks,” first author Wendy Shoop, a scientist at Precision Biosciences, told BioWorld.

One of the largest med-tech deals of 2023 was wiped off the charts when Medtronic plc terminated a $738 million agreement to acquire South Korean wearable insulin patch maker Eoflow Co. Ltd., citing “multiple breaches” under its agreements, on Dec. 6.

Artificial Intelligence (AI) driven tools have the ability to design new drugs, with a bit of help from humans, said Anders Hogner, from Astrazeneca plc’s R&D department at the Bio-IT World Conference & Expo Europe in London. “We don’t have anything out there yet,” he added, but the company appears to be working on it.
