Critical implications of IVDR for innovation in diagnostics: input from the BioMed alliance diagnostics task force

With the implementation of Regulation (European Union [EU]) 2017/746 on in vitro diagnostic medical devices (IVDR), from May 26, 2022, onwards, the development and use of diagnostic tests will be governed by a vastly expanded and upgraded EU regulatory framework. We provide here an overview of the amended transition timelines, the role of notified bodies, EU reference laboratories, expert panels, and the Medical Device Coordination Group (MDCG). We also describe the implications of the IVDR for innovative laboratory medicine by explaining the exemption for in-house devices (IH-IVDs). Two key challenges faced by the academic diagnostic sector are: (1) the stipulation on equivalence of tests (article 5.5d), which poses a new condition for the use of IH-IVDs and (2) the gray area between CE marked in vitro diagnostics (CE-IVDs), modified CE-IVDs, Research Use Only (RUO) tests, and IH-IVDs. Furthermore, the results of a questionnaire on current diagnostic practice conducted by European medical societies collaborating in the BioMed Alliance indicate widespread use of IH-IVDs in diagnostic laboratories across Europe and emphasize the need for support and guidance to comply with the IVDR. Diagnostic equivalents of the European Reference Networks (ERNs) for rare diseases could help ensure affordable and equal access to specialized diagnostics across the EU. Concerted action by clinical and laboratory disciplines, regulators, industry, and patient organizations is needed to support the efficient and effective implementation of the IVDR in a way that preserves innovation and safeguards the quality, safety, and accessibility of innovative diagnostics.Peer reviewe

Combined Chemoradionuclide Therapy Using Poly(ε-caprolactone-b-ethylene oxide) Micelles as the Delivery Vehicle

Combination of therapies is a common strategy in cancer treatment. Such combined therapies only have merit provided that there is superior therapeutic outcome with fewer side effects, compared to single therapies. Here, this work explores the possibility to combine chemotherapy with radionuclide therapy using polymeric micelles as a delivery vehicle. For this purpose, this work prepares poly(ε-caprolactone-b-ethylene oxide) (PCL-PEO) micelles and load them simultaneously with paclitaxel (PTX) and 177Lu(III). This work chooses a 3D tumor spheroid composed of glioblastoma cells (U87) to evaluate the combined treatment. The diffusion of the micelles in the spheroid is investigated by confocal laser scanning microscopy (CLSM) and light-sheet fluorescence microscopy (LSFM). The results show that the micelles are able to penetrate deep into the spheroid within 24 h of incubation and mainly accumulated around or in the lysosomes once in the cell. Subsequently, this work evaluates the cell killing efficiency of the single treatments (PTX or 177Lu(III)) versus combined treatment (PTX + 177Lu(III)) by measuring the growth of the spheroids as well as by performing a cell-viability assay. The results indicate that the combined therapy achieves a superior therapeutic outcome with better cell growth inhibition and cell killing efficiency compared to the single treatments
