Abstract
Background: The major drug regulatory agencies have approved chimeric antigen receptor (CAR) T cells for the treatment of some B-cell lymphoproliferative diseases. Their use is expanding, and new indications will be approved. Efficient mononuclear cell collection by apheresis providing enough T cells is a critical step in further CAR T-cell manufacturing process. It is important that apheresis units are prepared for the collection of the required T cells for manufacturing with the highest efficiency and safety for the patient.
Summary: Several series have studied different characteristics that could influence the collection efficiency of T cells for CAR T-cell manufacturing. Also, an effort has been made to identify predictors of the total number of target cells collected. Despite these publications and the large number of ongoing clinical trials, consensus protocols in apheresis are scarce.
Key messages: The aim of this review was to summarize the set of measures described to optimize apheresis and ensure patient safety. Moreover, we also propose, in a practical approach, a way to apply this knowledge to the daily routine in the apheresis unit.
期刊介绍:
This journal is devoted to all areas of transfusion medicine. These include the quality and security of blood products, therapy with blood components and plasma derivatives, transfusion-related questions in transplantation, stem cell manipulation, therapeutic and diagnostic problems of homeostasis, immuno-hematological investigations, and legal aspects of the production of blood products as well as hemotherapy. Both comprehensive reviews and primary publications that detail the newest work in transfusion medicine and hemotherapy promote the international exchange of knowledge within these disciplines. Consistent with this goal, continuing clinical education is also specifically addressed.
