Cell & Gene Therapy Product Characterization
Cell and gene therapy products are a class of therapeutic drugs requiring special attention and understanding when it comes to the presence and characterization of visible and sub-visible particulate matter.
The presence and characterization of visible and sub-visible particulate matter in parenteral products is a critical consideration during development, manufacturing, clinical and commercial release, and investigations. Established analytical methodologies for testing and regulatory guidance is well understood for pharmaceutical parenteral products; however, specific methodologies for cell and gene therapy products are not as mature.
The detection of particulate matter defects, or “foreign particulate matter” in cell and gene therapy products is a critical aspect to both manufacturing and quality assurance. Gateway Analytical employs several analytical methodologies to characterize and determine the potential sources of such particulates. Detection and characterization of foreign particulates is vital to the pharmaceutical manufacturing process, and a cohesive program should address remediation, reduction and ultimately elimination of foreign particulate matter.
