The technical and regulatory aspects of drug development and production, encompassing the chemical composition of the drug substance, its manufacturing process, and the controls implemented to ensure its quality and consistency, are collectively referred to as the CMC section of a regulatory submission. The provision of complete and accurate CMC data is crucial for regulatory authorities to evaluate the safety, efficacy, and quality of a drug, and to ascertain its eligibility for approval and marketing authorization. Hence, it is imperative for pharmaceutical companies to furnish comprehensive CMC information in their regulatory submissions.
The CMC section of a regulatory submission typically includes information about the drug substance and drug product, such as their physicochemical properties, methods of manufacture, specifications, stability data, and analytical methods used to test the product. The CMC section is a crucial part of the Common Technical Document (CTD) format, which is the standard format for regulatory submissions in the EU, Japan, and other countries.
Regulatory work in CMC involves authoring, compiling, and checking regulatory submissions and interacting directly with personnel at regulatory bodies through strategy. Regulatory submission complexities have always been a matter of concern for smaller emerging biotechs. Submission requirements are increasingly stringent, and the applications involve a significant amount of documentation and data. Therefore, it is crucial to plan for detailed and well-audited applications, supplements, and amendments by collecting data throughout the development process. Developing a refined regulatory strategy with defined CMC data is essential for a successful regulatory submission.
Here are some of the challenges and considerations in CMC:
- Ensuring that meaningful data will be generated during phase 3 studies to support a planned marketing application.
- Focusing on CMC issues related to the Phase 3.
- Keeping up with regulatory and technical changes presents an enormous cost and operational challenge for the pharmaceutical industry which must process a large volume of changes every year for existing products.
- Ensuring that all CMC practices are updated accordingly as regulatory requirements and expectations change with time.
- Identifying and rectifying compliance issues if a company as a marketing authorization holder has a portfolio of products where it is suspected there may be a divergence between registered CMC details and manufacturing practice.
- Ensuring that the CMC section of a regulatory submission includes complete and accurate data about the drug substance and drug product, such as their physicochemical properties, methods of manufacture, specifications, stability data, and analytical methods used to test the product.
To address these challenges and considerations, pharmaceutical companies can implement a well-designed CMC compliance program and its efficient implementation by experts. This can help ensure that products and services satisfy the expectations of patients, and customers, and are in full compliance with applicable regulations and other health-related requirements. The CMC regulatory compliance outcome provides essential insight into how far product and process have developed. The measurement of compliance can give rise to conflicts of interest, as the results can be seen as a measure of a function’s performance. Therefore, it is essential to use impartial methods to ensure a level of impartiality.
