PCT’s analytical development team works with clients to create testing methods that satisfy the Chemistry Manufacturing and Controls (CMC) requirements of an IND or BLA filing with the FDA. PCT develops analytical methods used for testing cell therapy products for identity, purity,
Cell surface phenotype associated with the therapeutic cell of interest (e.g., expression of the chimeric antigen receptor for CAR T cells, expression of CD4 and FoxP3 by regulatory T cells, expression of
Examples would include cell surface marker expression associated with unwanted/contaminating cells (typically by flow cytometry)
Examples might include suppression of T cell proliferation by regulatory T cells, cytotoxicity assay for antigen-specific T cells, ability to form capillary-like structures for endothelial progenitor cells.
Also, for product release, surrogate markers associated with
Compendial tests are typically used, but quick surrogate assays are sometimes developed for products that need to be infused fresh (an example would include Mycoplasma PCR)
For example, cellular proliferation assay to determine that tumor cell component used in some cancer therapies has been inactivated.
