257 - 21 CFR Part 4 Explained: CGMP Requirements for Combination Products

21 CFR Part 4 sets the CGMP requirements for combination products. If your product has a drug and a device in it, you're on the hook for both sets of regulations. In this video, I walk through Part 4 Subpart A section by section: the scope, the key definitions, which CGMPs apply, and the two ways to comply, including the streamlined approach under 4.4(b).

Updated for February 2026, when the device side moved to the QMSR and ISO 13485, plus the new medical gas provisions.
