Understanding Gene Therapy

Traditional therapeutic approaches often focus on treating the symptoms of diseases. However, a paradigm shift is underway in the medical field, with a growing emphasis on addressing the underlying causes of diseases. Leading this transformation is gene therapy, a groundbreaking area of precision medicine that targets the genetic drivers of diseases, rather than their symptoms. This approach offers the potential to revolutionize disease treatment and usher in a new age of precision medicine.

At the forefront of this transformation is Precision BioSciences, Inc., a clinical stage biotechnology company. The company is harnessing the power of its ARCUS genome editing platform to develop in vivo gene correction therapies for cancer and infectious diseases. The ARCUS platform illustrates the practical application of gene therapy in addressing critical health issues, underlining the potential of this approach to improve life.

Gene therapys potential extends beyond cancer and infectious diseases. Its also being applied in the context of inflammatory diseases, offering solutions that range from correcting genetic defects to precise immune modulation. These therapies have demonstrated the potential to alleviate symptoms, improve quality of life, and achieve disease remission. Both patient and animal model studies have yielded favorable results, attesting to the transformative impacts of gene-based interventions on various inflammatory diseases.

While the potential of gene therapy is immense, its high cost can be prohibitive. For example, gene therapies for sickle cell disease (SCD), a condition that affects over 100,000 people in the U.S., can cost as much as $2.8 million for a one-time dose. To address this, the U.S. is launching a Cell and Gene Therapy (CGT) Access Model in January 2025. This initiative, part of the Administrations effort to drive down prescription drug costs, aims to lower the high cost of gene therapies and improve quality of care. By tying pricing for SCD treatments to improved health outcomes, the CGT Access Model represents a promising step towards making gene therapies more accessible.

Researchers are also exploring gene therapy for rare immune disorders. A recent study demonstrated the use of a gene editing technique to treat a rare immune disorder caused by deficiencies in recombination activating genes (RAGs). The treatment targets the RAG1 gene using homology-directed repair (HDR) processes. This approach offers the unique advantage of editing the affected gene while preserving its normal regulation. This proof-of-concept demonstration of therapeutically relevant HDR correction of the RAG1 locus for the treatment of RAG1 deficiency underscores the potential of gene editing techniques in gene therapy. Furthermore, it supports further study of this exonic gene editing platform towards clinical testing.

With the continual development of innovative technologies like the ARCUS genome editing platform and the U.S. governments proactive steps to make gene therapies more accessible, the future of gene therapy looks promising. As research advances, we can anticipate a future where gene therapy becomes a mainstay in the treatment of a wide array of diseases, truly ushering in a new age of precision medicine.
