These institutions are often the first to adopt investigational ERTs under compassionate use or expanded access frameworks.

 

4. Payers and Public Health Systems

While not traditional end users, insurance payers and national health agencies play a vital role in therapy adoption. Their assessment of cost-effectiveness, burden of disease, and treatment durability determines access, particularly in public-funded markets.

 

Use Case: Pompe Disease Management in South Korea

A tertiary hospital in Seoul implemented an early-diagnosis and intervention protocol for Pompe disease using enzyme replacement therapy ( Alglucosidase Alfa). By integrating newborn screening, enzyme assay confirmation, and genetic testing within a 3-day window, the hospital was able to initiate treatment before major muscle degeneration set in.

Over a 12-month follow-up period, patients demonstrated significantly better respiratory and cardiac function outcomes compared to historical controls diagnosed post-symptom onset. The initiative, supported by national reimbursement, has now been expanded as a model across other East Asian countries.

This use case underscores how early detection infrastructure, streamlined diagnostics, and public funding can jointly transform patient outcomes in diseases where time-to-treatment is critical.
