Cells examples of indications sources

Cells: Examples of Indications/Sources

  • Pancreatic islets for diabetes

  • Stem and skeletal muscle progenitor cells for ischemic cardiac

  • Hematopoietic reconstitution in treatment of malignancies

  • Stem cells for metabolic storage diseases

  • Stem cells for CNS indications (Parkinson’s disease)

  • Expanded autologous cartilage for joint repair


Regulatory requirements for initiating clinical trials

Regulatory Requirements for Initiating Clinical Trials

  • Individual subject safety must be balanced against the potential public health benefits of new therapies

  • Risk assessment requires sufficiently detailed information regarding:

    • Product characterization and safety testing

    • Preclinical data supporting safety

    • Eligibility criteria

    • Product administration procedure

    • Clinical safety monitoring


Common issues that delay initiation of clinical trials

Common Issues that Delay Initiation of Clinical Trials

  • Product to be used in the trial different from that used in preclinical studies

  • Insufficient preclinical data to support safety of product administration to humans

  • No information about compatibility of product and delivery device

  • Inadequate plan for monitoring of subjects after product administration


Outreach meetings policy development
