title: Handling of gene-transfer products by the National Institutes of Health Clinical Center pharmacy department.
abstract: Policies and procedures for handling gene-transfer products at the National Institutes of Health (NIH) Clinical Center pharmacy department are described. The pharmacy at the Clinical Center is responsible for handling in vivo gene-transfer delivery systems, which are gene-transfer products that are prepared for direct administration to patients. The gene-transfer products currently handled by the pharmacy are investigational and are composed of viruses containing the gene encoding either of the melanoma antigens MART-1 and gp100. The pharmacy has prepared guidelines, based on the principles of aseptic technique and FDA guidelines for manufacturing facilities, intended to help pharmacy personnel safely dilute a concentrated gene-transfer product into a dose suitable for administration. Before a product is handled, the biological safety level is determined and a biohazard sign is posted. Worksheets detailing all supplies, calculations for dilutions, and procedures that will be required are prepared in advance; the worksheets are part of a drug fact sheet prepared for all investigational drugs dispensed. Personnel must be properly trained and dressed in protective clothing. Aseptic technique and decontamination procedures are used as specified in the guidelines, and all materials used are disposed of as biohazardous waste. All work is documented. If a worker is accidentally exposed, standard procedures are followed. The handling of gene-transfer products at the NIH Clinical Center pharmacy is based on the principles of aseptic technique, FDA guidelines, and experience.
