Emerging from its 'Dark Age'


Gene and cell therapy have encountered various setbacks but are now living up to their promises. Gene therapy involves introducing a healthy gene into cells with defective copies in their genetic libraries. The therapeutic gene then instructs these cells to manufacture functional proteins, replacing the faulty ones. Meanwhile, cell therapy, such as CAR-T, modifies patients' cells to combat cancer-related diseases. The main challenge has been ensuring that the treatment gene or modified cells target the suitable cells in the appropriate tissue and are delivered to millions of these cells without disrupting neighboring genes.



Another challenge has been ensuring that the gene or modified cells produce adequate protein or therapeutic effects to be effective. Despite these challenges, scientists have made significant progress. In 1999, an 18-year-old participant in a trial died due to liver failure shortly after receiving an experimental gene therapy dose for a rare metabolic disorder, causing the field to reassess. However, more promising advances are finally beginning to emerge.



Recent Advancements in Gene & Cell Therapy: A New Era of Treatment


The life sciences industry has been incredibly encouraged by the gene and cell therapy field, which recognizes the gene's role as the fundamental unit of heredity and the potential of cellular modifications. The goal of precisely altering the human genome and modifying cells has been a long-standing objective, which genetics and bioengineering have made possible by manipulating vectors to deliver extrachromosomal material to target cells and enhance their therapeutic potential.


Delivery vehicles, such as plasmids, nano-structured materials, or viruses, are the primary focus of these techniques, and cell modification and transplantation methods are continually being improved. Even with the proficiency of viruses in invading cells and inserting genetic material, there are concerns about heightened immune responses and genome manipulation, particularly in germ-line cells.


Despite these challenges, gene and cell therapy have seen numerous advancements recently, such as the recommendation of Breyanzi (lisocabtagene maraleucel) for marketing authorization in the EU by the European Medicines Agency, a CAR-T cell therapy for adult patients with diffuse large B-cell lymphoma (DLBCL), primary mediastinal large B-cell lymphoma (PMBCL), and follicular lymphoma grade 3B (FL3B) whose cancer has returned or has not responded to treatment after two or more lines of systemic therapy.

Gene and cell therapy have transformed the treatment landscape for various diseases, such as Luxturna, a gene therapy for rare inherited blindness, and Zolgensma, a gene therapy for spinal muscular atrophy. This devastating genetic disorder affects infants.


In vivo, studies in somatic cells have shown promising results with approved protocols in clinical trials conducted in the United States, Europe, Australia, and China. Recent biotechnological advances, such as induced pluripotent stem cells in patients with liver diseases, chimeric antigen receptor T-cell immunotherapy, and genomic editing by CRISPR/Cas9, are also being explored in this field.

The Impact of Gene & Cell Therapy on the Life Sciences Industry


The advent of gene and cell therapy has revolutionized the life sciences industry, offering exciting new avenues for research and development. By targeting the root cause of various diseases, these therapies have the potential to create innovative therapeutic solutions that were once unimaginable. This cutting-edge technology has also spurred innovation in fields like virology and nanotechnology.


However, the development and production of gene and cell therapies require extensive technical expertise, and their approval and supervision entail regulatory elements. Ethical considerations surrounding gene editing and cell modification technologies must also be considered.


Regardless, the life sciences industry invests heavily in gene and cell therapy. Companies collaborate with academic institutions to advance this technology, and healthcare providers, payers, and patients are impacted. Healthcare providers require specific knowledge and skills to administer these treatments correctly, while payers need to create new reimbursement models for these high-cost, one-time treatments. Patients must also be educated about gene and cell therapy's potential benefits and risks.


As we continue to explore the possibilities of gene and cell therapy, we can expect even more significant changes. The life sciences industry is poised to make substantial breakthroughs in treating various diseases, and this transformative technology is redefining the industry as a whole.



The Challenges of Gene & Cell Therapy


The potential of gene and cell therapy is immense, but significant challenges still need to be addressed. One of the most pressing hurdles is finding an effective way to deliver therapeutic genes or cells to their target cells. While viral vectors and cell transplantation techniques are currently the most commonly used methods, concerns about their safety and efficacy persist. Researchers are actively working to develop new, safer, and more efficient delivery methods.


Another major challenge is the risk of triggering an immune response. The immune system may not recognize the therapeutic gene, viral vector, or transplanted cells as part of the body. It may launch an attack, which can reduce the effectiveness of the therapy and even harm the patient. Experts are exploring ways to mitigate this risk and improve the overall safety of gene and cell therapy.


Finally, the high cost of gene and cell therapy is a significant barrier to access. While these treatments can cure diseases, they are often prohibitively expensive for many patients. Policymakers and stakeholders are considering innovative payment models and reimbursement policies to make these treatments more affordable and accessible to those who need them. In spite of these challenges, researchers remain optimistic that they can overcome these obstacles and unlock the vast potential of gene and cell therapy.



The Future of Gene & Cell Therapy


Dr. Roger J. Hajjar, Director of the Gene and Cell Therapy Institute at Mass General Brigham and a recent addition to Atamyo Therapeutics Board of Directors, believes that gene and cell therapy has the potential to transform the medical field by offering cures for previously incurable illnesses.


However, several challenges must be addressed to fully realize the potential of these therapies. These challenges include overcoming technical hurdles, managing immune responses, and addressing ethical and regulatory concerns. It is also vital to ensure that these cutting-edge treatments are accessible to all patients.


Despite these challenges, the future of gene and cell therapy looks promising. These innovative treatments can cure numerous genetic and cellular-level diseases, ushering in a new era of medicine. As we continue to deepen our understanding of genetics and cellular biology and refine our gene and cell therapy techniques, we can look forward to a future where many of today's incurable diseases can be treated or cured.
