Patents

United States Patent 5434135 :

The invention in growth factor compositions includes: a novel compound which is a separate pure nicked or pure non-nicked species of epidermal growth factor EGF1-48 or its hEGF1-47 or hEGF1-49 congener compound, or a pharmaceutically acceptable salt thereof; a pharmaceutical composition in dosage form comprising an effective amount of the novel compound and/or the known hEGF1-53; and use thereof for treating abnormal cell growth conditions including gastrointestinal/duodenal lesions; and methods of making the pure novel hEGF species. This unique therapeutic utility is enhanced by the unexpected and heretofore unappreciated structural stability and resistance of the pure species to enzymatic degradation, Filed on 1993-01-25.
