Biopharmaceutical Process and Product Related Impurities Analysis

Share

During the drug development process, unknowns often arise from impurities and degradation products that can be formed during the manufacturing process or storage of the new drug. Current United States Food and Drug Administration (USFDA) regulatory guidance requires that studies be conducted to identify the impurities present in a new drug substanceand to characterize their structure.

A well-characterized biopharmaceutical is defined during its development by identification and quantification of both process and product related impurities. Product-related impurities in the drug substance are molecular variants with properties different from those of the desired product formed during manufacture and storage. Creative BioMart has built a strong track record analyzing product related impurities and detailed analysis of product variants.
