  • Patent number: H1899
    Abstract: A method for determining a concentration of IGF-I that defines a therapeutically effective dose of IGF-I, i.e., a dose that will provide a therapeutic response in the treatment of neurological disorders for which IGF-I is utilized (including peripheral neuropathy, diabetic neuropathy, post-polio syndrome, small fiber neuropathy, ALS, and MS) is described. The method comprises determining whether a particular dose of IGF-I causes a 1.5 fold or greater increase in the homeostatic concentration of plasma IGFBP-2 in a mammal that has previously received a defined dose of IGF-I. The method of the invention can also be used to determine whether or not biological tolerance has developed to a particular dose of IGF-I.
