Cder guidance validating chromatographic methods

This is the essence of Quality by Design, and the best means currently available to ensure patient safety and efficacy.” “The most effective regulatory approach for the CMC [chemistry, manufacturing, and controls] section is based on a strong understanding of the molecule and process, with the application of appropriate risk analysis tools to provide a probabilistic estimate of process and attribute risk,” he says.“When it comes to the CMC section of the marketing application, there is nothing better than presenting a thorough understanding of the biochemical, biophysical and biological properties of the molecule.

Thus, significant changes in the method can create a substantial discontinuity between past and future data sets.Regulatory Elements Regulatory authorities generally encourage sponsors to adopt new technologies whenever feasible to enhance understanding of product quality and/or testing efficiency.That is what the “C” in CGMP means: current good manufacturing practice, in which quality control (QC) tests are part of a total control strategy to ensure that each product batch is high quality.The guidance document provides recommendations for submitting analytical procedures and method validation data to the FDA to support the documentation of the identity, strength, quality, purity, and potency of drug substances and drug products.It applies to drugs covered in new drug applications (NDAs), abbreviated new drug applications (ANDAs), biologics license applications (BLAs) and amendments to those applications.

These meetings focus on relevant chemistry, manufacturing, and controls (CMC) issues throughout the lifecycle of such products and thereby foster collaborative technical and regulatory interaction.
