Title:	Treatment of rett syndrome using glycyl-L-2-methylprolyl-L-glutamic acid
Abstract:	This invention provides compounds, compositions and methods for treating Autism Spectrum Disorders (ASD) using glycyl-2-methylprolyl-glutamic acid (G-2-MePE) and analogs thereof. Autism Spectrum Disorders include Autism, Autistic Disorder, Asperger Syndrome, Childhood Disintegrative Disorder, Pervasive Developmental Disorder—Not Otherwise Specified (PDD-NOS), Fragile X Syndrome, and Rett Syndrome. Compositions containing compounds include water-soluble formulations, water-in-oil micro-emulsions, water-in-oil coarse emulsions, water-in-oil liquid crystals, nanocapsules, tablets, and orally administered gels. The compounds and compositions of this invention can be administered intravenously, intraventricularly, parenterally, or orally, and can be effective in treating neurodegeneration, promoting neurological function, treating seizure activity and other symptoms of ASD, and can prolong life in animals including human beings having Autism Spectrum Disorders.

Application Number:	US14/605,420
Patent Claims:	1. A method for treating a human being suffering from a symptom of Rett Syndrome, comprising oral administration to said human being an effective amount of an aqueous solution of Glycyl-2-Methyl-L-prolyl-L-glutamate (G-2-MePE). 2. The method of claim 1, said effective amount of G-2-MePE being in the range of about 1 mg/Kg to about 100 mg/Kg. 3. The method of claim 1, where said G-2-MePE is administered in a dose of about 60 mg/kg twice per day (“b.i.d.”). 4. The method of claim 1, where said G-2-MePE is administered to a mucosa of said human being. 5. The method of claim 1, further comprising administering to the human being a second therapeutic agent selected from a group consisting of: insulin-like growth factor-I (IGF-I), insulin-like growth factor-II (IGF-II), glycyl-prolyl-glutamate (GPE), transforming growth factor-β1, activin, growth hormone, nerve growth factor, brain-derived neurotrophic factor (BDNF), growth hormone binding protein, IGF-binding proteins (especially IGFBP-3), basic fibroblast growth factor, acidic fibroblast growth factor, the hst/Kfgk gene product, FGF-3, FGF-4, FGF-6, keratinocyte growth factor, androgen-induced growth factor, int-2, fibroblast growth factor homologous factor-1 (FHF-1), FHF-2, FHF-3, FHF-4, keratinocyte growth factor 2, glial-activating factor, FGF-10 and FGF-16, ciliary neurotrophic factor, brain derived growth factor, neurotrophin 3, neurotrophin 4, bone morphogenetic protein 2 (BMP-2), glial-cell line derived neurotrophic factor, activity-dependant neurotrophic factor, cytokine leukaemia inhibiting factor, oncostatin M, interleukin), α-interferon, β-interferon, γ-, consensus interferon, TNF-α, clomethiazole; kynurenic acid, Semax, tacrolimus, L-threo-1-phenyl-2-decanoylamino-3-morpholino-1-propanol, andrenocorticotropin-(4-9), analog [ORG 2766], dizolcipine (MK-801), selegiline; mematine, NPS1506, GV1505260, MK-801, GV150526; 2,3-dihydroxy-6-nitro-7-sulfamoylbenzo(f)quinoxaline (NBQX), LY303070, LY300164; anti-MAdCAM-1mAb, MECA-367 (ATCC accession no. HB-9478), fenobam, fluoxetine, and risperidone. 6. The method of claim 1, where said dose of said compound is 10 mg/kg three times per day or 30 mg/kg three times per day. 7. The method of claim 1, said treatment producing an improvement in said symptom as assessed by one or more behavioral test selected from the group consisting of The Rett Syndrome Natural History/Clinical Severity Scale, Aberrant Behavior Checklist Community Edition (ABC), Vinelands, Clinical Global Impression of Severity (CGI-S) and their carers completed the Caregiver Strain Questionnaire (CSQ), or one or more physiological test selected from the group consisting of electroencephalogram (EEG) spike frequency, overall power in frequency bands of an EEG, hand movement, QTc and heart rate variability (HRV), and respiratory irregularities compared to control animals not suffering from said symptom.
