Summary of "Pre-clinical to clinical translational failures and current status of clinical trials in stroke therapy: a brief review."

In stroke (brain ischemia), the leading cause of functional disability and mortality worldwide, despite continuous efforts both at experimental and clinical level in getting the better understanding, the only approved pharmacological treatment has been restricted to tissue plasminogen activator (tPA). Its complex pathophysiology starts with energy pump failure which ends with neuronal cell death. Ischemic cascade involves excessive glutamate release followed by raised intracellular sodium and calcium influx along with free radicals' generation, activation of inflammatory cytokines, NO synthases, lipases, endonucleases and other apoptotic pathways leading to cell edema and death. At pre-clinical stage, several agents have tried and proven as an effective neuroprotectant in animal models of ischemia. However, these agents failed to show convincing results in terms of efficacy and safety when the trials were conducted in humans following stroke. This article highlights the various agents which have tried in the past but failed to translate into stroke therapy along with key points that are responsible for lagging of experimental success to translational failure in stroke treatment.

Medical and Biotech [MESH] Definitions

Works about randomized clinical trials that compare interventions in clinical settings and which look at a range of effectiveness outcomes and impacts.

Work that is the report of a pre-planned clinical study of the safety, efficacy, or optimum dosage schedule of one or more diagnostic, therapeutic, or prophylactic drugs, devices, or techniques in humans selected according to predetermined criteria of eligibility and observed for predefined evidence of favorable and unfavorable effects. While most clinical trials concern humans, this publication type may be used for clinical veterinary articles meeting the requisites for humans. Specific headings for specific types and phases of clinical trials are also available.

Works about randomized clinical trials that compare interventions in clinical settings and which look at a range of effectiveness outcomes and impacts.

Works about a study where participants are assigned to a treatment, procedure, or intervention by methods that are not random. Non-randomized clinical trials are sometimes referred to as quasi-experimental clinical trials or non-equivalent control group designs.

A work that reports on the results of a research study to evaluate interventions or exposures on biomedical or health-related outcomes. The two main types of clinical studies are interventional studies (clinical trials) and observational studies. While most clinical studies concern humans, this publication type may be used for clinical veterinary articles meeting the requisites for humans.
