A priority research area for our New Modalities Group is to evaluate and further develop a variety of techniques for the targeted delivery of novel drug molecules to diseased tissue. The ultimate goal is to apply the most effective and innovative targeting strategies to the next generation of medicines, achieving excellent efficacy and vastly superior safety profiles compared to current treatments, thus bringing the maximum benefit to patients. We have developed expertise in targeted delivery of cytotoxic compounds into tumor tissues in the context of antibody-drug-conjugates (ADCs). Building on this experience, we will now look beyond ADCs and investigate the opportunities and limitations of passive targeted delivery approaches that rely on the enhanced permeability and retention effect. Drawing from our extensive experience in linker chemistry, we aim to design the next generation of tissue targeting systems that would release drugs only at the desired site of action, thus maximizing their therapeutic window.
One aspect of our approach is to evaluate dendrimers as carriers for drug delivery. Dendrimers represent a flexible and modular approach that will enable the exploration of specific drug release mechanisms in combination with tissue-targeting modalities. We aim to develop novel linkers and dendrimer scaffolds and evaluate biological activity of the resulting constructs in vivo.
