CMC Technical Authoring involves the creation of content on chemistry, manufacturing, and controls of drug substances and drug products, typically part of Module 2.3 and Module 3 of CTD.
These modules contain comprehensive information about the development, manufacturing, and control of process parameters (CPP) and quality attributes (CQA) of the pharmaceutical product as defined in ICH M4Q guidance documents.
The information is split across multiple sections to capture information about composition, manufacturing process, in-process checks, and analytical methods.
Collaborative Team
Describes the structure, properties and characteristics of the active pharmaceutical ingredient.
Additional information on the synthesis / extraction process, impurity profile,
analytical methods used for characterization or any pharmacopeial reference for testing methods.
Drug Product Composition
Describes the final product that includes other components along with active ingredient like
excipients, colorants, coating agents, binders, etc., The formulation, dosage form, and
specifications for each ingredient is well structured and unambiguously documented.
Manufacturing Process
The description of the drug’s manufacturing process is a central element of the CMC section.
This includes information on equipment used, critical process parameters,
and controls implemented to ensure consistency and quality.
Control of Critical Steps and Intermidiates
Critical steps and intermediates in the manufacturing process are identified, and controls
are established to monitor and regulate these elements. This ensures that the final product
consistently meets the desired quality attributes.
Specifications
Specifications define the acceptable ranges for various quality attributes of the drug substance
and drug product. These include physical
and chemical characteristics, potency, purity, and stability criteria.
Analytical Procedures
The CMC section details the analytical methods used to assess the quality of the drug at different
stages of development and production. This includes validation data demonstrating the reliability
and accuracy of these methods.
Stability Studies
Comprehensive stability studies are conducted to assess the drug product’s stability over time under various
conditions. This information is crucial in determining the product’s
shelf life and storage recommendations.
