Cardiac gene therapy in large animals: bridge from bench to bedside

Area of Science:

• Cardiovascular Research
• Gene Therapy
• Translational Medicine

Background:

• Gene transfer is a promising therapeutic strategy for cardiac diseases.
• Advances in gene delivery and understanding mechanisms fuel optimism for cardiac gene therapy.
• Small animal models have limitations due to physiological differences from human hearts.

Purpose of the Study:

• To emphasize the necessity of large animal studies for preclinical validation of cardiac gene therapy.
• To highlight key factors influencing therapeutic efficacy and safety.
• To underscore the role of large animal models in translating research to clinical practice.

Main Methods:

• Review of existing knowledge on gene transfer for cardiac diseases.
• Discussion of the limitations of small animal models.
• Emphasis on the importance of large animal models for preclinical evaluation.

Main Results:

• Large animal studies are essential for validating efficacy in a human-relevant model.
• Key factors like vector type, dose, delivery, and disease target critically impact outcomes.
• Comprehensive safety and efficacy evaluations are best performed in large animal models.

Conclusions:

• Large animal studies are a prerequisite for ensuring safe and effective cardiac gene therapy in humans.
• Optimizing gene therapy parameters in large animals is vital for successful clinical translation.
• Large animal models are indispensable for advancing cardiac gene therapy from bench to bedside.
