Abstract

A phase I clinical trial is being currently performed in our institution, aiming at evaluating the feasibility and toxicity related to the administration of Herpes Simplex-thymidine kinase gene-expressing human primary T lymphocytes following allogeneic hematopoietic stem cell transplantation. The need for safe and standardized preparation conditions for gene-modified cells is crucial. We describe the closed culture system used in the current trial for ex vivo retroviral-mediated gene transfer and transduced cell selection. Cell handling is performed in closed systems using sampling and transfer pack bags, culture bags and a sterile connection device which avoids opening the culture system. This closed system allows safe and reproducible ex vivo preparation of gene-modified primary T-lymphocytes for clinical use.
