33. 29 April 2016, AS33 5.5 Characterization of Impurities Impurity: A foreign agent or material either introduced as part of processing (such as buffers or salts added during chromatography) or intrinsic to the nature of bioprocessing (such as product variants and cellular debris).

34. 29 April 2016, AS34 5.5 Characterization of Impurities Impurity Profile: (ICH Q3B (R2)) A description of the identified and unidentified impurities present in a drug product.

35. 29 April 2016, AS35 5.5 Characterization of Impurities Impurity Profile: A description of the identified and unidentified impurities present in a typical batch of API (Active Pharmaceutical Ingredient) produced by a specific controlled production process. It includes the identity or some qualitative analytical designation (e.g. retention time), the range of each impurity observed, and type of each identified impurity. For each API there should be an impurity profile describing the identified and unidentified impurities present in a typical batch. The impurity profile is normally dependent upon the process or origin of the API.

36. 29 April 2016, AS36 5.5 Characterization of Impurities The impurities are derived from 1. Process-related impurities and contaminates: -Cell substrates ( e.g., host cell protein, host cell DNA) -Cell culture (e.g., inducers, antibiotics, Serum, media component) -Downstream ( e.g., enzymes, chemical and biochemical processing reagents )

37. 29 April 2016, AS37 5.5 Characterization of Impurities The impurities are derived from 2. Product-related impurities including degradation products: -Truncated forms: Hydrolytic enzymes or chemicals may catalyse the cleavge peptide bonds. -Other modified forms: Deamidated, isomerised, mismatched S-S linked, oxidiesd -Aggregates: includes dimers and higher multiples of the desired product.

41. 29 April 2016, AS41 5.6 Justification of Specification The setting of specifications for drug substance and drug product is part of an overall control strategy which includes control of raw materials and excipients, in- process testing, process evaluation or validation, adherence to Good Manufacturing Practices, stability testing, and testing for consistency of lots. When combined in total, these elements provide assurance that the appropriate quality of the product will be maintained. Since specifications are chosen to confirm the quality rather than to characterize the product, the manufacturer should provide the rationale and justification for including and/or excluding testing for specific quality attributes. The following points should be taken into consideration when establish in scientifically justifiable specifications. (ICH Q 6 B )

42. 29 April 2016, AS42 5.6 Justification of Specification Based on data from Linked to a manufacturing process. Account for the stability of drug substance and drug product. Linked to preclinical and clinical studies. Linked to analytical procedures
