Abstract:
The presentation will look at the role of impurities in complex biological molecules. Typically, there are no therapeutic benefits to be derived from impurities. Therefore, all impurities should be removed or controlled to the extent possible to meet product specifications, good manufacturing practices (GMP), or other quality or safetybased criteria and drug products should contain no higher levels of residual impurities than can be supported by safety data and/or process capability. The focus will then switch to regulatory requirements for impurities that are enshrined in ICH Q3A / ICH Q3B and ICH Q6B; as well as other related impurity guidance for residual solvents (ICH Q3C), residual elemental impurities (ICH Q3D) and residual mutagenic impurities (ICH M7). The presentation will then focus on the typical types of impurities in biological molecules before looking at an assessment of the process capability (Cpk) and impurity purging capability of the process. Then the focus will switch to allowable safety margins and the typical risk assessments that are needed to support the safety margins, before providing some concluding remarks.
