Abstrakt: Background Aims: According to European Directive 2001/83/EC, chimeric antigen receptor T (CAR T) cells belong to a new class of medicines referred to as advanced therapy medicinal products (ATMPs). The specific features and complexity of these products require a total reorganization of the hospital circuit, from cell collection from the patient to administration of the final medicinal product. In France, at the cell stage, products are under the responsibility of a cell therapy unit (CTU) that controls, manipulates (if necessary) and ships cells to the manufacturing site. However, the final product is a medicinal product, and as with any other medicine, ATMPs have to be received, stored and further reconstituted for final distribution under the responsibility of the hospital pharmacy. The aim of our work was to perform a risk analysis of this circuit according to International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use Q9 guidelines on quality risk management.
Methods: We evaluated the activities carried out by the Saint-Louis Hospital CTU and pharmacy. Process mapping was established to trace all the steps of the circuit and to identify potential risks or failures. The risk analysis was performed according to failure mode, effects and criticality analysis. The criticality of each risk (minor [Mi], moderate [Mo], significant [S] or major [Ma]) was scored, and corrective actions or preventive actions (CAPAs) for Mo, S and Ma risks were proposed.
Results: We identified five Mo, six S and no Ma risks for the CTU part of the process. The most frequent risk was traceability failure. To reduce its frequency, we developed and validated software dedicated to ATMP activities. Another S risk was non-compliance of CAR T cell-specific steps due to the significant variability between companies. Our CAPA process was to implement procedures and design information sheets specific to each CAR T-cell program. In addition, critical steps were added to the ATMP software. Our CAPA process allowed us to reduce the criticality of identified risks to one Mi, seven Mo and three S. For the pharmacy part of the process, five Mo, two S and one Ma risk were identified. The most critical risk was compromised integrity of the CAR T-cell bag at the time of thawing. In case of unavailability of a backup bag, we designed and validated a degraded mode of operation allowing product recovery. In this exceptional circumstance, an agreement has to be signed between the physician, pharmacy, CTU and sponsor or marketing authorization holder. The implemented CAPA process allowed us to reduce the criticality of risks to three Mi and five Mo.
Conclusions: Our risk analysis identified several Mo and S risks but only one Ma risk. The implementation of the CAPA process allowed for controlling some risks by decreasing their frequency and/or criticality or by increasing their detectability. The close collaboration between the CTU and pharmacy allows complete traceability of the CAR T-cell circuit, which is essential to guarantee safe use.
