Formulation: An industry perspective on compatibility assessment of closed system drug-transfer devices for biologics
BioPhorum Formulation Workstream has identified the increased use of closed system drug-transfer devices (CSTDs) with biologics, without an associated compatibility assessment, to be of significant concern. The use of CSTDs has increased significantly in recent years due to the recommendations by NIOSH and USP that they be used during preparation and administration of hazardous drugs. While CSTDs are valuable in the healthcare setting to reduce occupational exposure to hazardous compounds, these devices may present particular risks that must be adequately assessed prior to use to ensure their compatibility with specific types of drug products, such as biologic drugs, which may be sensitive. The responsibility of ensuring quality of biologic products through preparation and administration to the patient lies with the drug product sponsor. Due to the significant number of marketed CSTD systems, and the large variety of components offered for each system, a strategic, risk-based approach to assessing compatibility is recommended herein. In addition to traditional material compatibility, assessment of CSTD compatibility with biologics should consider additional parameters to address specific CSTD-related risks. In this paper published in the Journal of Pharmaceutical Sciences the Workstream has proposed a systematic risk-based evaluation approach as well as a mitigation strategy for establishing suitability of CSTDs for use.
