Advanced Therapy Medicinal Products (ATMPs), including gene therapies, tissue-engineered products, and somatic cell therapies, present unique regulatory challenges and opportunities. In 2023, the FDA continues to refine expectations for Chemistry, Manufacturing, and Controls (CMC) aspects of Biologics License Applications (BLAs) for these innovative therapies. This article serves as a comprehensive step-by-step tutorial for industry professionals navigating CMC review hotspots in the context of ATMP BLAs, with a focus on practical actions and documentation expectations aligned with FDA guidelines.

Step 1: Understanding the Regulatory Framework for ATMPs

The first essential step in ATMP regulatory consulting is to familiarize yourself with the FDA’s regulatory framework, specifically under the Biologics Control Act and subsequent guidance documents. This framework is governed by the relevant sections of the Federal Food, Drug, and Cosmetic Act (FDCA) and incorporates unique provisions for ATMPs.

The FDA provides clear definitions and classifications for ATMPs, distinguishing them from traditional medicinal products. Key regulatory milestones include the designation of ATMPs under the Regenerative Medicine Advanced Therapy (RMAT) designation. This status can speed up development timelines and facilitate access to accelerated approval pathways, which is critical for innovative therapies addressing serious or life-threatening conditions.

Recommended resources for understanding the regulatory criteria include FDA’s Guidance for Industry: Expedited Programs for Regenerative Medicine Therapies for Serious Conditions. Comprehensive knowledge of this framework will lay the groundwork for subsequent steps in the CMC review process.

Step 2: Pre-IND Consultation and INTERACT Meetings

Engaging with the FDA early in the development process is crucial. The Pre-Investigational New Drug (Pre-IND) meeting serves as a formal opportunity to seek feedback on the proposed development plan, including CMC. During this meeting, ensure your team presents comprehensive data that encapsulates product characterization, manufacturing process, and quality control measures. Specifically, focus on:

• Product Characterization: Detailed descriptions of the cellular or gene product, including identity, purity, and potency testing.
