Recent developments in gene therapy research in India

J Biosci. 2024;49:37.ABSTRACTInherited genetic disorders are progressive in nature and lead to organ dysfunction or death in severe cases. At present, there are no permanent treatment options for >95% of inherited disorders. Different modes of inheritance, type of gene(s) involved, and population-based variations add further complexity to finding suitable cures for approximately 400 million patients worldwide. Gene therapy is a very promising molecular technique for the treatment of rare genetic disorders. Gene therapy functions on the basis of restoration, replacement, inhibition, and, most recently, editing of gene(s) to rescue the disease phenotype. Recent reports show that increasing numbers of gene therapy clinical trials are using viral vectors (64.2%) when compared with non-viral vectors. Rapid development of efficient viral vector systems like the adeno-associated virus (AAV) and lentivirus has significantly contributed to this progress. Notably, AAV-mediated gene therapy has shown high potential for genetic disease treatment as evident from recent clinical trials for the eye (NCT00999609), blood (NCT00979238), and neuro-muscular systems (NCT02122952). Safety and efficacy are the two most critical features required for vector(s) to qualify for pre-clinical and clinical trial approval. The process of clinical-grade vector production, evaluation, and approvals for gene therapy products requires significant technological development, knowledge enhancement, and large f...
