HCT/P regulations addressing contamination
  • Current Good Tissue Practices (CGTP)
  • 21 CFR 1271.145*

You must recover, process, store, label, package, and distribute HCT/Ps, and screen and test cell and tissue donors, in a way that prevents the introduction, transmission, or spread of communicable diseases.

*Applies to all HCT/Ps, including “351” products

21 cfr 1271 150 cgtp requirements 361 products

21 CFR 1271.150 CGTP requirements (“361” products)

You must follow CGTP requirements to prevent the introduction, transmission, or spread of communicable diseases by HCT/Ps (e.g., by ensuring that the HCT/Ps do not contain communicable disease agents, that they are not contaminated, and that they do not become contaminated during manufacturing). Communicable diseases include…those transmitted by bacteria, fungi, parasites, and TSE agents.

Specific CGTP provisions (“361” products)
  • Sec. 1271.160(b)(2): Quality program must ensure that procedures exist for sharing information pertaining to possible contamination
  • Sec. 1271.160(c): Facility controls to prevent contamination
  • Sec. 1271.195(a) and (c): Environmental control and monitoring where conditions could be expected to cause contamination
  • Sec. 1271.200(b): Equipment maintenance to prevent contamination

Specific CGTP provisions (“361” products, with exception)
  • Sec. 1271.215: Recover in a way that does not cause contamination
  • Sec. 1271.220(a): Process in a way that does not cause contamination
  • Sec. 1271.260(a): Control of storage areas to prevent contamination
  • Sec 1271.265(c)(2)*: You must not make available for distribution an HCT/P that is… contaminated… or that otherwise does not meet release criteria designed to prevent communicable disease transmission

*Applies to all HCT/Ps, including “351” products
