Manufacturing investigational medicinal products (IMP)s and ancillary supplies is a complex process, and it is subject to change at every stage. There is much at stake for both sponsors and clinical research organisations (CROs), from being responsible for IMPs that represent millions of dollars in investment to the health of patients involved in the trials. As if manufacturing of IMPs wasn’t challenging enough, the appropriate storage and distribution of such sensitive products can be an adventurous journey by itself if not carefully planned and managed. Jens Mattuschka, Vice President – Clinical Logistics Services at PAREXEL International, gives us an insight into clinical trial material storage and distribution.
