Zusammenfassung der Projektergebnisse

Translational stroke research has yielded only one thrombolytic and no neuroprotective therapy over the last decades. Indeed, there is no specific therapy for approximately 45% of patients who suffer from post-stroke disabilities. Interestingly, only single-drug targets were hitherto pursued, whilst we now know that complex diseases are precisely defined by multitarget modules. In addition, preclinical stroke models frequently ignore real-world clinical comorbidities. Here, I propose an in silico-based multitarget approach based on human disease genes linked to ischaemic stroke to identify potential targets subsequently validated in a preclinical model. Specifically, I followed a network pharmacology therapeutic approach where several components of a disease module were simultaneously targeted, combining mechanistically related and thus synergistic drugs. Moreover, to maximally speed-up market entry, we followed a drug repurposing strategy which ensures therapeutic safety and quick access to the pharmaceutic market. This program resulted in a triple network pharmacology therapy (Objective 1) currently been translated to the clinics (Phase II trial), later extended to a long-term ischaemic therapeutic approach (Objective 2). Additionally, we identified a potential stroke biomarker, determining the best therapeutic frame for acute therapy (Objective 4). Finally, I am currently working on extending our findings to a vascular dementia animal model for later validation of a mechanism-based network pharmacology therapy (Objective 3).
