Current avenues of gene therapy in Pompe disease

by informer

Pompe disease is a rare, inherited condition that causes progressive weakness, cardiomyopathy and neuromotor disease due to the accumulation of glycogen in striated and smooth muscle, as well as neurons. While enzyme replacement therapy has dramatically changed the outcome of patients with the disease, this strategy has several limitations. Gene therapy in Pompe disease constitutes an attractive approach due to the multisystem aspects of the disease and need to address the central nervous system manifestations. This article reviews the recent work in this field, including methods, progress, shortcomings, and future directions.

Recombinant adeno-associated virus and lentiviral vectors are well studied platforms for gene therapy in Pompe disease. These products can be further adapted for safe and efficient administration with concomitant immunosuppression, with the modification of specific receptors or codon optimization. Recombinant adeno-associated virus has been studied in multiple clinical trials demonstrating safety and tolerability.

Gene therapy for the treatment of patients with Pompe disease is feasible and offers an opportunity to fully correct the principal pathology leading to cellular glycogen accumulation. Further work is needed to overcome the limitations related to vector production, immunologic reactions and redosing. Read the full article here.
