What happened

The FDA issued a warning letter to Blue Horizon International, LLC following an investigation by the Center for Biologics Evaluation and Research (CBER).

Who it affects

Blue Horizon International, LLC and professionals involved in the manufacturing, marketing, and clinical application of cellular and regenerative medicine products.

Why it matters

The involvement of CBER indicates that the FDA likely identified issues regarding the regulatory classification of the company's products, potentially treating them as unapproved biologics rather than human cells, tissues, or cellular and tissue-based products (HCT/Ps). This signifies continued agency scrutiny on the regenerative medicine sector and the enforcement of premarket authorization requirements for products that do not meet specific exemptions.

Practical takeaway

Review the regulatory status of any stem cell or regenerative medicine products to ensure they meet the criteria for Section 361 HCT/Ps or have an approved BLA/IND. Verify that all marketing claims align with authorized indications and do not inadvertently classify a tissue product as a drug or biologic.
