    摘要: Sustained delivery formulations comprising a water-insoluble complex of a peptide and a carrier macromolecule are disclosed. The formulations of the invention allow for loading of high concentrations of peptide in a small volume and for delivery of a pharmaceutically active peptide for prolonged periods, e.g., one month, after administration of the complex. The complexes of the invention can be milled or crushed to a fine powder. In powdered form, the complexes form stable aqueous suspensions and dispersions, suitable for injection. In a preferred embodiment, the peptide of the complex is an LHRH analogue, preferably an LHRH antagonist, and the carrier macromolecule is an anionic polymer, preferably carboxymethylcellulose. Methods of making the complexes of the invention, and methods of using LHRH-analogue-containing complexes to treat conditions treatable with an LHRH analogue, are also disclosed.

    摘要: Chimeric antibodies comprised of the variable region of an antibody chain contiguous with a polypeptide other than the constant region of that antibody chain are disclosed. Such chimeric antibodies can be comprised of the variable region of a chain of an immunoglobulin of selected specificity and an extrinsic polypeptide. In addition to the variable region of a chain of an immunoglobulin of selected specifity and an extrinsic polypeptide, the chimeric antibodies can include at least a portion of the constant region of an immunoglobFUNDING SOURCESThe work described herein was supported by grants from the National Institutes of Health, the American Cancer Society and the Damon Runyon--Walter Winchell Cancer Fund.
