Controlled release CGRP delivery composition for cardiovascular and renal indications
First Claim
1. A method of treating heart failure in a patient, comprising delivering to said patient CGRP in an amount effective to provide symptomatic relief, or delay progression of the disease state of heart failure in said patient, wherein said CGRP is delivered to said patient as a controlled release composition,wherein said controlled release composition comprises a flowable thermoplastic polymer composition comprising a biocompatible polymer, a biocompatible solvent and CGRP and said composition is delivered to a bodily tissue or fluid in said patient, wherein the amounts of the polymer and the solvent are effective to form a biodegradable polymer matrix containing CGRP in situ when said composition contacts said bodily fluid tissue or fluid,wherein the polymer matrix comprises between about 5% and 15% CGRP by weight and said CGRP is released from said polymer matrix at a rate that will maintain circulating plasma levels of CGRP between 11±
- 5 pg/ml and 186±
127 pg/ml over a period of 7 to 180 days.

Abstract
The present invention provides methods of treating heart failure and improving renal function, and/or preventing the advancement of heart failure into advanced stages, and methods of counteracting ischemia due to a myocardial infarction by providing improved methods of administering a therapeutically effective amount CGRP as a controlled release formulation. The therapies can be administered on an outpatient or inpatient basis and can further be used as maintenance therapies.

23. A method of treating heart failure in a patient, comprising administering a flowable composition comprising a biocompatible polymer, a biocompatible solvent and CGRP to a bodily tissue or fluid in said patient, wherein the amounts of the polymer and the solvent are effective to form said polymer matrix comprising CGRP in situ when the formulation contacts said bodily fluid tissue or fluid wherein polymer matrix comprises between about 5% and 15% CGRP by weight and said CGRP is released from said polymer matrix at a rate between about 0.0008 and 0.016 μ
- g/min/kg body weight over a period of 7 to 180 days.
