2
The main bottleneck in cell and gene therapy is delivery, with issues in manufacturing complexity, cost, and logistics.
-
3
Progress in understanding therapy failures includes insights into resistance, antigen escape, and tumor microenvironment suppression.
-
4
Regulatory decisions impact the cost and access of therapies, shaping their development and delivery despite not controlling prices.
-
5
Successful cell and gene therapy programs must focus on scalable manufacturing, efficient delivery, and early engagement with stakeholders.
