Gene therapy is a new therapeutic approach in which genes are used to treat or prevent diseases. It is a comprehensive term which encompasses a large variety of therapy products including viral and bacterial vectors, plasmid DNA, human geneediting technology, and patient-specific cellular gene therapy.
Preliminary results from the study — just the second to show that CRISPR-based geneediting can be delivered systemically and performed inside the body — found the treatment, NTLA-2002, reduced levels of the disease-causing protein, kallikrein, by 65% and 92% in the low- and high-dose cohort, respectively.
Bayer has bolstered its cell and gene therapy platform by securing access to a CRISPR-based gene-editing platform developed by US biotech Mammoth Biosciences. CRISPR drugs can be used to modify the expression of disease-associated proteins in the body, for example, by correcting a mutation in a specific gene.
The company has also stated, at the same time as the study was announced, that it will look at developing mRNA technology in oncology and geneticdiseases. This not only allowed Pfizer to establish a COVID-19 vaccine but the company also recently announced that it had begun a study testing an mRNA flu vaccine.
The CRISPR geneediting system consists of the Cas9 enzyme, which serves as molecular scissors to cleave double-stranded DNA, and a guide RNA template targeted to a specific genomic sequence, which allows for precise editing. Epigenetic Editing with CRISPR.
The disease occurs due to a point mutation in the hemoglobin beta globin ( HBB ) gene that codes for one of the proteins that make up hemoglobin, the oxygen carrier in red blood cells. Casgevy’s approval by the FDA is momentous: it is the first CRISPR-based gene-editing therapy to be approved in the US.
The RNA Revolution: From mRNA Vaccines to RNA Editing. RNA, and its protein-generating form messenger RNA (mRNA) discovered in 1961 , has quickly transitioned from being an obscure, finicky molecule that is difficult to work with, to becoming a significant cornerstone of therapeutic innovation in pharma and biotech.

Moreover, AI has the potential to identify features and signs of disease that may be overlooked by human experts, offering a new layer of diagnostic capability. RNA-based therapies hold the potential to offer new treatment options for diseases with limited or inadequate therapeutic alternatives.
