The role of quality management system in the monitoring and continuous improvement of GMP-regulated short-lived radiopharmaceutical manufacture

Abstract

The last decade has seen extraordinary growth in the clinical use of Positron Emission Tomography (PET), an in vivo molecular imaging modality widely used in oncology that requires the use of radiopharmaceuticals labeled with short-lived radionuclides. These medicinal products have found widespread application in Nuclear Medicine departments equipped with PET scanners. Due to the great increase in radiopharmaceutical demand, their production has been centralized and moved to industrial manufacturing sites in which Good Manufacturing Practice (GMP) principles and guidelines for medicinal products are to be applied. The production of PET radiopharmaceuticals features particular aspects such as the use of the lot before the completion of all tests, the multiplicity of batches produced per single day and the absence of product stock due to radionuclide short half-life. In this context, the application of quality principles to all stages of the process and the implementation of a quality management system (QMS) are of primary importance. This paper reports on the development of a QMS applied to a GMP manufacturing site of an in vivo PET diagnostic product, and on how its application can describe the performance of the site. Data were collected over a 6-year period (2008–2013) and demonstrate the ability of Key Performance Indicators, strictly related to the structure and organization of the QMS, and quality tools (data analysis, internal audit, etc.) to monitor process performance in terms of effectiveness, efficacy and stability.
