Definitions
- TECHNICAL FIELD The subject matter described herein relates to methods of intranasal administration of active agents to the central nervous system of a mammal.
- the permeability of the epithelial tight junctions in the body is variable and is typically limited to molecules with a hydrodynamic radius less than 3.6A; permeability is thought to be negligible for globular molecules with a radius larger than 15A (B. R. Stevenson et al., MoI. Cell. Biochem. 83,129-145(1988)). Therefore, the size of the molecule to be administered is considered an important factor in achieving intranasal transport of a macromolecule to the central nervous system.
- Fluorescein-labeled dextran a linear molecule having a dextran molecular weight of 20 kD can be delivered to cerebrospinal fluid from the rat nasal cavity, however 40 kDa dextran cannot (Sakane et al, J. Pharm. Pharmacol. 47, 379-381 (1995)). It has also been reported that an infectious organism, such as a virus, can enter the brain through the olfactory region of the nose (S. Perlman et al., Adv. Exp. Med. Biol., 380:73-78 (1995)).
- intranasal delivery efficiency to the CNS has been very low and the delivery of large globular macromolecules, such as antibodies and their fragments, has not been demonstrated.
- antibodies, antibody fragments, and antibody fusion molecules are potentially useful therapies for treating disorders having CNS a target, e.g., Alzheimer's disease, Parkinson's disease, multiple sclerosis, stroke, epilepsy, and metabolic and endocrine disorders, it is desirable to provide a method for delivering these large macromolecules to the CNS non-invasively.
- a method for targeting a polypeptide to the CNS by attaching the polypeptide to an antibody or an antibody fragment to form a fusion polypeptide, and administering the fusion polypeptide intranasally is provided.
- the polypeptide is biologically active and provides a therapeutic benefit.
- the antibody or antibody fragment biologically active and provides a therapeutic benefit, in addition to having binding affinity for an endogenous target, such as a cell or tissue.
- intranasal administration of the therapeutic composition is provided for treatment of a condition that responds to or requires delivery of the therapeutic compound to the CNS.

- FIG. 6 is a graph showing the percentage reduction in cumulative food intake in rats, as a function of time, in hours, after intranasal treatment with ⁇ -MSH mimetibody at a dose of 2.5 nmol (diamonds), 6.25 nmol (squares), 25 nmol (triangles), or 50 nmol (circles),
- FIG. 7 is a bar graph showing the cumulative food intake in rats, in grams, at the indicated times post treatment with ⁇ -MSH mimetibody (open bars) or saline (dotted bars) administered intranasally.
- compositions are applied intranasally such that the compositions will be transported to the brain directly, such as by a non-systemic route. Accordingly, methods of delivering therapeutic compositions to the central nervous system of a mammal are provided herein. Methods of treating a disorder responsive to treatment by application of a therapeutic composition to the central nervous system of a mammal are also provided and described below.

- the method may be used to treat a wide variety of disorders.
- Suitable disorders include, for example, neurological and neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, and Huntington's disease, as well as other disorders known to the art that cause a loss of memory, such as multi-infarct dementia, Creutzfeldt-Jakob disease, Lewy body disease, normal pressure hydrocephalus and HIV dementia; or a loss of locomotion, such as stroke, amyotropic lateral sclerosis, myasthenia gravis and Duchenne dystrophy; endocrine, metabolic or energy balance disorders, such as obesity, diabetes and sleeping disorders, including insomnia; autoimmune disorders, such as multiple sclerosis; anorexia and treatment of acute injury from stroke or spinal cord injuries.

- a method of delivering a therapeutic composition to the central nervous system of a mammal includes administering the composition to the mammal intranasally, preferably to olfactory and/or trigeminal nerve endings, cells and nasal epithelium in a region of the nasal cavity located in the superior turbinates. This region or area is typically located in, but is not limited to, the upper one-third portion of the nasal cavity.
- the agents that are applied intranasally according to the methods described herein may reach the brain directly by an extracellular or intracellular pathway. See, e.g., Thome, R. G. et a/., Neuroscience, 127:481-496 (2004).
- Intracellular pathways include transport through olfactory sensory neurons. This may involve, for example, absorptive or receptor-mediated endocytosis into olfactory sensory neurons and subsequent transport to olfactory bulb glomeruli.

- This amount will vary depending on the time of administration, the route of administration, the duration of treatment, the specific composition used and the health of the patient as known in the art. The skilled artisan will be able to determine the optimum dosage.
- compositions By intranasally administering the compositions by the methods described herein, it is realized that a smaller amount of the composition may be administered compared to systemic administration, including intravenous, oral, intramuscular, intraperitoneal, transdermal, etc.
- the amount of active agent and/or compositions required to achieve a desired clinical endpoint or therapeutic effect when intranasally administered as described herein may be less compared to systemic administration.
