Beginning 29 December 2023, the Modernization of Cosmetic Regulation Act of 2022, which was signed into law last year to establish a more strengthened US Food and Drug Administration regulatory framework to ensure the safety of cosmetic products, will begin to take effect. Like with cosmetic application, prepping for full coverage to comply with the new law is important.

On 3 April 2023, FDA issued a draft guidance for industry, Marketing Submission Recommendations for a Predetermined Change Control Plan for Artificial Intelligence/Machine Learning (AI/ML)-Enabled Device Software Functions, for manufacturers whose medical devices use machine learning technologies to improve patient care. Through the draft guidance, FDA intends to provide a least burdensome approach to support iterative improvements to machine learning-enabled device software functions or ML-DSFs through modifications, while continuing to provide a reasonable assurance that the device is safe and effective. In essence, manufacturers can proactively seek FDA’s concurrence with the intended modifications to the applicable devices without additional marketing submissions for each modification in the future.

On 24 March 2023, a notice was published in the Federal Register announcing that the Food and Drug Administration published a framework for the use of digital health technologies (DHTs) in drug and biological product development. DHTs are systems that use computing platforms, connectivity, software, and/or sensors for health care and related uses. FDA previously published draft guidance identifying considerations for the use of DHTs to support clinical investigations and relating to different aspects of DHT use. In the draft guidance, FDA particularly highlighted the importance of verification and validation to ensure the DHTs are for fit-for-purpose for use in the clinical investigation. Further, remote data acquisition through DHTs may raise issues including data privacy and confidentiality concerns.

On 13 March 2023, FDA issued a notice regarding guidance documents related to the COVID-19 pandemic, including which of the guidance documents will no longer be in effect after expiration of the declaration of the COVID-19 public health emergency (PHE). The notice followed a Department of Health and Human Services announcement on 9 February that it is planning for the declaration of the PHE to expire on 11 May 2023.

On 6 March 2023, FDA issued a Dietary Supplement Ingredient Directory. The Directory is hosted on the agency’s website and is intended to help the public quickly find what the FDA has said about a specific ingredient and whether the agency has taken any action with regard to the ingredient. Importantly, the Directory will replace the previous FDA Dietary Supplement Ingredient Advisory List, which listed ingredients identified by the agency as not lawfully marketed in dietary supplements.

On 24 January 2023, the US Food and Drug Administration issued draft guidance on action levels for lead in certain categories of processed foods intended for babies and children under two years of age. These action levels reflect levels of lead at which FDA may regard the food as adulterated within the meaning of section 402(a)(1) of the Federal Food, Drug & Cosmetic Act. FDA will consider these action levels when determining whether to bring an enforcement action.
