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. But science does not stop.
4D Molecular Therapeutics Inc. (4DMT) and Arbor Biotechnologies Inc. have established a strategic partnership focused on advancing new AAV-based gene-editing therapies for central nervous system (CNS) diseases with high unmet medical need in both rare and common disease populations.
After the initial approvals in monogenic inherited diseases, the scope of gene therapy is widening, with new delivery routes, novel vectors, cell-specific targeting and products aiming to treat chronic disorders, all making headway in 2023.

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.
With a landmark U.K. approval in hand for Casgevy (exagamglogene autotemcel [exa-cel]) to treat sickle cell disease and transfusion-dependent beta thalassemia, Crispr Therapeutics AG and partner Vertex Therapeutics Inc. are turning their attention to the PDUFA dates set by the U.S. FDA for the treatment in both conditions.
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.
Alterations in chromosome number can play a role in cancer progression. An analysis of recurrent aneuploidies, such as the duplication of the long arm of chromosome 1, revealed that it was required for the proliferation of cancer cells carrying this alteration, an effect that was similar to so-called oncogene addiction. These findings have therapeutic implications that could benefit cancer patients depending on the genetic singularity of their tumor cells.
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.
The discovery of DNA was a milestone in the history of science that led to a breakthrough in biomedical research. By associating disease and genetics, genome correction techniques were ultimately developed that are supposed to work in the same way that antibiotics and antivirals block pathogenic microorganisms: by directly attacking the causes of disease.
