FDA Enforcement Trends Under 21 CFR Part 1271

The U.S. Food and Drug Administration (FDA) enforces compliance with 21 CFR Part 1271 Section 361 and applicable provisions of the Public Health Service Act governing Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps).

This enforcement analysis forms part of the broader Biologic Product Portfolio.

Enforcement activity primarily focuses on improper regulatory classification, non-homologous use positioning, expanded therapeutic claims, and failure to comply with Current Good Tissue Practice (cGTP) requirements.

Educational overview of FDA risk-based enforcement escalation applicable to HCT/P establishments.

Scope of FDA Oversight

FDA oversight of HCT/P establishments may include:

  • Inspection of registered facilities
  • Review of labeling, advertising, and website representations
  • Evaluation of donor eligibility documentation under Subpart C
  • Assessment of manufacturing controls under Subpart D (cGTP)

Regulatory classification under Section 361 vs Section 351 and adherence to the Subparts A–D regulatory structure significantly affect enforcement exposure and compliance obligations.

Common Enforcement Themes

Publicly issued warning letters and enforcement actions frequently involve:

  • Claims implying treatment, cure, or mitigation of disease
  • Failure to meet minimal manipulation standards
  • Non-homologous intended use positioning
  • Combination with non-exempt active ingredients
  • Inadequate cGTP compliance controls

Marketing language, sales materials, and digital content are routinely evaluated in classification and enforcement analysis.

Warning Letters & Regulatory Action Pathways

When compliance concerns arise, the FDA may initiate:

  • Warning letters
  • Untitled letters
  • Form FDA 483 inspection observations
  • Seizure or injunction proceedings in severe cases

Warning letters and inspection findings are publicly accessible and form part of the regulatory record.

Regulatory Risk Mitigation

Regulatory exposure is reduced through disciplined compliance alignment:

  • Strict adherence to homologous use standards
  • Clear documentation supporting minimal manipulation
  • Verified donor eligibility processes
  • Documented cGTP quality systems
  • Conservative and accurate marketing language

Consistent regulatory positioning strengthens defensibility under Section 361.

Recent Enforcement Focus Areas

Recent FDA enforcement trends have emphasized:

  • Expanded therapeutic positioning of perinatal tissue products
  • Systemic effect claims inconsistent with Section 361 eligibility
  • Unregistered manufacturing establishments
  • Failure to maintain adequate cGTP documentation

Proper regulatory alignment requires integrated evaluation of:
