Special Issue Information

Dear Colleagues,

The field of drug delivery systems has grown exponentially in the past decade with the production of many bioconjugated macromolecules and nanocarriers for clinical applications in oncology, gene therapy, immunology, as well as inflammatory and infectious diseases. The rationale for the use of drug delivery systems relies on the fact that most “native” drugs administered by systemic injection distribute evenly throughout the body, resulting in low plasma drug concentration, limited bioavailability, rapid metabolism, and side-effects in healthy organs. Drug delivery systems appear as suitable tools to achieve prolonged plasma concentrations of therapeutic payloads and higher site-specific delivery.

This Special Issue seeks to describe advanced drug delivery systems such as peptide- and polymer-bioconjugates, monoclonal antibodies, affitins or supramolecular aggregates, and lipid/polymer nanocarriers designed to improve their drug loading (radiopharmaceutics, xenobiotics, peptides, or nucleic acids), stealth properties, biocompatibility, and organ/cell targeting through the development of specific chemical synthesis and functionalization. This Special Issue will consider contributions on the synthesis and physicochemical characterization of drug delivery systems, as well as their in vitro cell uptake and biocompatibility, their mode(s) of administration, and their biotechnological, pharmaceutical, and diagnostic applications.

1C1m-Fc, an anti-tumor endothelial marker 1 (TEM-1) scFv-Fc fusion protein antibody, was previously successfully radiolabeled with 177Lu. TEM-1 specific tumor uptake was observed together with a non-saturation dependent liver uptake that could be related to the number of dodecane tetraacetic acid (DOTA) chelator per 1C1m-Fc. The objective of this study was to verify this hypothesis and to find the best DOTA per 1C1m-Fc ratio for theranostic applications. 1C1m-Fc was conjugated with six concentrations of DOTA. High-pressure liquid chromatography, mass spectrometry, immunoreactivity assessment, and biodistribution studies in mice bearing TEM-1 positive tumors were performed. A multi-compartment pharmacokinetic model was used to fit the data and a global pharmacokinetic model was developed to illustrate the effect of liver capture and immunoreactivity loss. Organ absorbed doses in mice were calculated from biodistribution results. A loss of immunoreactivity was observed with the highest DOTA per 1C1m-Fc ratio. Except for the spleen and bone, an increase of DOTA per 1C1m-Fc ratio resulted in an increase of liver uptake and absorbed dose and a decrease of uptake in tumor and other tissues. Pharmacokinetic models correlated these results. The number of DOTA per antibody played a determining role in tumor targeting. One DOTA per 1C1m-Fc gave the best pharmacokinetic behavior for a future translation of [177Lu]Lu-1C1m-Fc in patients. Full article
