A practical approach for gmp-compliant validation of real-time PCR method for mycoplasma detection in human mesenchymal stromal cells as advanced therapy medicinal product

A PCR protocol to establish standards for routine mycoplasma testing that by design detects over ninety percent of all known mycoplasma species

Mycoplasma infection leads to false and non-reproducible scientific data and poses a risk to human health. Despite strict guidelines calling for regular mycoplasma screening, there is no universal and widely established standard procedure. Here, we describe a reliable and cost-effective PCR method that establishes a universal protocol for mycoplasma testing. The applied strategy utilizes ultra-conserved eukaryotic and mycoplasma sequence primers covering by design 92% of all species in the six orders of the class Mollicutes within the phylum Mycoplasmatota and is applicable to mammalian and many non-mammalian cell types. This method can stratify mycoplasma screening and is suitable as a common standard for routine mycoplasma testing.

Analysis of GMP for marketing authorization of ATMPs: comparison in the US, the EU, Japan and South Korea

Aim: This study compared regulatory systems of competent authorities related to GMP for marketing authorization of advanced therapy medicinal products (ATMPs). Methods: Dossiers for GMP and regulations and guidelines for facilities and equipment were analyzed using gap analysis. The risk-based approach (RBA) and GMP inspection were evaluated with regulations and guidelines. Results: The dossier was similar for the competent authorities. However, whereas a site master file is required in the EU, Japan and South Korea, the US requires only a biologics license application. The regulations and guidelines of facilities and equipment emphasized preventing contamination. There are differences among the competent authorities in GMP inspection and RBAs. Conclusion: Differences among the competent authorities in the marketing authorization process related to GMP for ATMPs should be considered.
