Methods to facilitate transmission of large molecules across the blood-brain, blood-eye, and blood-nerve barriers
A method for delivering a biologic to a human with Alzheimer's-related dementia, comprising administering the biologic parenterally into the perispinal space of the human without direct intrathecal injection, and thereafter positioning the human's head below the horizontal. The method further includes delivering a TNF antagonist to the brain of a human for treating mild cognitive impairment, Alzheimer's related dementia, or vascular dementia, comprising administering the TNF antagonist golimumab parenterally into the perispinal space of the human without direct intrathecal injection, and thereafter positioning the human in a Trendelenburg position, for delivery of the golimumab to the brain via the human's vertebral venous system.
1. A method for delivering a biologic to a human with Alzheimer's-related dementia, comprising the steps of administering said biologic parenterally into the perispinal space of said human without direct intrathecal injection, and positioning said human in a Trendelenburg position.
2. The method of claim 1 , wherein said biologic is etanercept.
3. The method of claim 1 , wherein said biologic is golimumab.
4. The method of claim 1 , wherein said biologic is immune globulin.
5. The method of claim 1 , wherein said biologic is bapineuzumab.
6. The method of claim 1 , wherein said administered biologic reaches the brain by retrograde blood flow, and thereby bypasses the blood-brain barrier to reach the brain.
7. The method of claim 1 , wherein the biologic is certolizumab pegol.
