Preventing airway mucus production by administration of EGF-R antagonists
View Patent ↗Hypersecretion of mucus in the lungs is inhibited by the administration of an epidermal growth factor receptor (EGF-R) antagonist. The EGF-R antagonist may be in the form of a small organic molecule, an antibody, or portion of an antibody that binds to and blocks the EGF receptor. The EGF-R antagonist is preferably administered by injection in an amount sufficient to inhibit formation of goblet cells in pulmonary airways. The degranulation of goblet cells that results in airway mucus production is thereby inhibited. Assays for screening candidate agents that inhibit goblet cell proliferation are also provided.
1. A method of treating nasal polyps, comprising administering a therapeutically effective amount of an epidermal growth factor receptor (EGF-R) antagonist to a patient suffering nasal polyps, wherein said EGF-R antagonist is a kinase inhibitor selective for EGF-R.
2. The method of claim 1 , wherein the antagonist is administered by injection.
3. The method of claim 2 , wherein the antagonist is administered intravenously with a carrier in the form of normal saline solution.
4. The method of claim 1 , wherein the antagonist is administered by liposome delivery.
5. The method of claim 4 , wherein said liposome is sterically stabilized and administered intravenously.
6. The method of claim 1 , wherein the antagonist is administered by inhalation.
7. The method of claim 6 , wherein the antagonist is in a dry powder formulation.
8. The method of claim 1 , wherein the antagonist is administered by oral delivery.
9. The method of claim 1 , wherein the antagonist is in an aqueous or ethanolic solution.
10. The method of claim 1 , wherein the patient is a human.
