Manufacturing Considerations for Licensed and Investigational Cellular and Gene Therapy Products During COVID-19 Public Health Emergency

FDA is issuing this guidance to provide manufacturers of licensed and investigational cellular therapy and gene therapy (CGT) products with risk-based recommendations to minimize potential transmission of the novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This guidance is intended to supplement the recommendations to drug and biological product manufacturers provided in FDA’s “Good Manufacturing Practice Considerations for Responding to COVID-19 Infection in Employees in Drug and Biological Products Manufacturing; Guidance for Industry” issued in June 2020 (Ref. 1) (June 2020 GMP Guidance). The recommendations in this guidance specifically consider the source material (cells and/or tissues) recovered from donors and how the CGT product will be manufactured (e.g., cell expansion in culture, viral reduction steps, formulation).
