Abstract
The invention provides animal models and clinical trials for assessing agents for potential use in treating and effecting prophylaxis stroke and other neurological diseases, particularly those mediated at least in part by excitoxitity. The invention also provides preferred dosage and infusion regimes and pharmaceutical compositions for clinical application of such agents.
Claims19
A method of treating or inhibiting or delaying at least one sign or symptom of a condition mediated by excitotoxicity, comprising administering to a human subject having the condition, or a risk factor associated with the condition, wherein the condition is stroke or traumatic injury to the CNS, the disease a pharmacological agent comprising a peptide with a C-terminal amino acid sequence of SEQ ID NO:38 that inhibits binding of PSD-95 to NMDAR 2B and/or of PSD-95 to nNOS, wherein when the agent is a peptide having the amino acid sequence YGRKKRRQRRRKLSSIESDV (SEQ ID NO:6), the dose is 2-3 mg/kg, and if the agent is other than the peptide having the amino acid sequence YGRKKRRQRRRKLSSIESDV (SEQ ID NO:6), the dose delivers the equivalent molar amount to 2-3 mg/kg of the peptide having the amino acid sequence YGRKKRRQRRRKLSSIESDV (SEQ ID NO:6).
A method of treating or inhibiting or delaying at least one sign or symptom of a condition mediated by excitotoxicity, comprising administering to a human subject having the condition, or a risk factor associated with the condition, wherein the condition is stroke or traumatic injury to the CNS, a pharmacological agent comprising a peptide with a C-terminal amino acid sequence of SEQ ID NO:38 that inhibits binding of PSD-95 to NMDAR 2B and/or PSD-95 to nNOS at a dose of 2-3 mg/kg, wherein the agent is linked to an internalization peptide, and the agent is administered by intravenous infusion over a period of 5-15 minutes.
A method of inhibiting ischemic damage from endovascular surgery to treat an aneurysm, diagnostic angiography or carotid stenting comprising administering an effective regime of an agent comprising a peptide with a C-terminal amino acid sequence of SEQ ID NO:38 that inhibits binding of PSD-95 to NMDAR 2B at a dose of 2-3 mg/kg to a subject undergoing the endovascular surgery or diagnostic angiography, wherein the agent is administered before or within one hour of completing the endovascular surgery or diagnostic angiography.
