ABSTRACT
The key challenges that are commonly faced by companies undertaking a tech transfer include: * Client expectations and initial project scope definition: the initial assumptions of the drug developer or marketing authorization holder (MHA) based on their initial information relating to the product can be a significant challenge. Typical examples include product stability issues (typically on legacy products) being evidenced due to a change to more compliant analytical methods;change to product brought about by compliance-related requirements on legacy products, such as nitrosamines, and elemental impurities guidelines, etc.;and regulatory requirements being misjudged at the onset of the project, among other factors. * Product knowledge management: particularly when undertaking tech transfers of legacy products or products in the initial discovery phase, there may be a lack of technical knowledge on the product itself to make a comprehensive and robust tech transfer process. All this may contribute to slowing down the transfer of knowledge, with implications for tech transfer timelines. * Standardization at receiving site: another challenge typically faced by receiving sites of CDMOs is a lack of standardization of their internal processes and or documentation brought about by multiple tech transfers with varying types of clients with multiple requirements. The originating site-particularly if it belongs to a small start-up-may not have team members with specialist experience in handling a transfer, so may need additional support in collating the required information to hand over to the receiving site.
