New goals in ischemic stroke therapy: the experimental approach--harmonizing science with practice

Area of Science:

• Neurology
• Translational Medicine
• Cerebrovascular Diseases

Background:

• Significant progress in understanding cerebral ischemia pathophysiology, diagnosis, and treatment.
• Many promising experimental treatments for cerebral ischemia fail to translate to clinical success.
• Intravenous thrombolysis and citicoline are exceptions to the general trend of clinical trial failures.

Purpose of the Study:

• To analyze discrepancies between laboratory findings and clinical outcomes in cerebral ischemia research.
• To identify lessons for improving research methodology and coordinating experimental and clinical studies.
• To explore novel therapeutic strategies for cerebral ischemia based on current research advancements.

Main Methods:

• Review and analysis of clinical and experimental data on cerebral ischemia treatments.
• Comparative assessment of drug efficacy in preclinical models versus human trials.
• Identification of factors contributing to the translational gap in cerebral ischemia research.

Main Results:

• A significant number of drugs effective in experimental models fail in clinical trials for cerebral ischemia.
• Discrepancies highlight the need for enhanced research coordination and methodology.
• Analysis provides insights into optimizing the power and cost-effectiveness of future studies.

Conclusions:

• Lessons learned from translational failures can refine research protocols for cerebral ischemia.
• New therapeutic avenues include combined pharmacological and mechanical thrombolysis.
• Emerging strategies involve combining neuroprotection, antiapoptotic therapies, and neurorestoration, including stem cell transplantation.
