Extractables and Leachables in Gene and Cell Therapies / The assessment of extractables from single-use systems · Hauk A, Pahl I, Budde D, Menzel R · Sartorius Stedim Biotech GmbH, Göttingen und
An evaluation is presented, demonstrating evidence that process equipment related leachables (PERLs) from single-use systems (SUS) pose low risk for gene and cell therapy applications. It is shown that available SUS extractables data can serve as a basis for the extractables and leachables assessment in cell and gene therapy (CGT) applications. However, exposure estimation and toxicological evaluation tools need improvement. Thus, a modeling concept was developed to calculate PERLs in the liquid phase and adsorbed on the therapeutic cells under dynamic process conditions. The model revealed PERL exposure levels to patients and cells which were significantly lower compared to those ...
