摘要:
Methods for treating sex hormone-dependent conditions are disclosed. The methods of the invention generally feature administration to a subject of an LHRH antagonist, in combination with a second therapy. In one embodiment, this second therapy is the performance of a procedure that removes or destroys tumor tissue, such as radical excision, cryosurgery or radiation therapy (external or interstitial). In another embodiment, the second therapy is treatment with an LHRH agonist, either simultaneously with or subsequent to LHRH antagonist therapy. The methods of the invention can further involve administering an antiandrogen and/or an inhibitor of sex steroid biosynthesis to the subject in combination with the LHRH antagonist. Methods for inhibiting the LHRH antagonist - induced hormone surge, whatever its clinical setting, are also disclosed. These methods generally involve administration of an LHRH antagonist in combination with the LHRH agonist. Complete suppression of the LHRH agonist-induced hormone surge has been achieved by pretreatment with a sustained-released formulation of LHRH antagonist.
摘要:
Sustained delivery formulations comprising a water-insoluble complex of a peptidic compound (e.g. a peptide, polypeptide, protein, peptidomimetic or the like) and a carrier macromolecule are disclosed. The formulations of the invention allow for loading of high concentrations of peptidic compound in a small volume and for delivery of a pharmaceutically active peptidic compound 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 peptidic compound 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.
