GOAL
  • Develop a Islet Transplant Program that would withstand the anticipated regulatory requirements
  • Practical for an academic institution’s financial constraints

cGMP, Co

  • Procedure that encompasses
  • cGMP for the manufacture of
  • biologics
  • BLA ready
  • Reimbursable
  • Standard Laboratory Practice
  • 2000 Reminder letter that FDA
  • regulates Islet Transplantation
  • 3/02 Guidance regarding validation
  • of processing human tissues for
  • transplantation

principles for biologic manufacturing
Principles for Biologic Manufacturing
  • Control and Validation of
    • Facility
    • Process
  • Goal: Make cellular (Islet) isolation conform to the Principles of Biologic Manufacturing

cGMP, Co

University of Chicago

facility
Facility
  • Early planning matching existing institutional assets with anticipated regulatory compliance- form a good plan
  • Define robust process that when modified does not effect integrity of facility (validated)
  • Early planning to control costs

cGMP, Co

University of Chicago

process
Process
  • Control the critical process environment to assure product safety and repeatability
    • Temperature
    • Bio-burden
    • Cross-contamination
  • Eliminate all equipment that cannot be validated to assure absence of contamination/cross contamination
  • Eliminate all components that require the use of undesirable substrates
  • Early training of staff to assure aseptic transfer of product (SOPs, training, QA/QC)
