Emerging neuroprotective drugs for the treatment of acute ischaemic stroke

Abstract

Introduction: Neuroprotection aims to restrict the ischaemic damage following stroke by preventing salvageable neurons from dying. Despite successes in experimental stroke studies, neuroprotective strategies have failed in clinical trials so far. Nevertheless, promising neuroprotective drugs are currently being investigated in clinical trials.

Areas covered: This review provides an overview of the existing treatment of acute ischaemic stroke, discusses current research goals and puts special emphasis on emerging neuroprotective drugs. The authors systematically searched the database Clinicaltrials.gov for ongoing Phase II and Phase III clinical trials of neuroprotective drugs for acute ischaemic stroke. Mechanisms of action of these candidate neuroprotectants and the results of preceding preclinical studies and clinical pilot trials are described.

Expert opinion: In order to facilitate a successful translation from bench to bedside, future experimental studies should follow rigorous quality standards. Recent concepts to overcome the translation roadblock include the implementation of multicentre preclinical Phase III studies, the use of stroke models in non-human primates and the introduction of a preclinical trial registration.
