| Abstract: | Stroke remains one of the main causes of death and disability worldwide. The aging of the population is likely to result in a dramatic increase in the burden of stroke. Thus, it is not surprising that the pharmaceutical industry has invested much money in the development of pharmacotherapies for ischemic stroke. Promising experimental data, however, have almost consistently failed to produce a clinically effective neuroprotective or neurorestorative drug. Only intravenous recombinant tissue plasminogen activator (rtPA) has been approved for the treatment of acute ischemic stroke. Many pharmaceutical companies have scaled down their stroke programs and despite the unmet need, activity in the field is almost frozen. Trafermin, a recombinant form of human basic fibroblast growth factor (bFGF), is a good example of a translational failure in neuroprotection. However, trafermin may also promote neuronal plasticity after cerebral insults. Thus, clinical trials with trafermin in stroke are warranted but should be based on neuronal restoration rather than acute neuroprotection. |
