Background
CD-NP (Cenderitide) is the only chimeric natriuretic peptide that acts on both the A and B natriuretic peptide receptors (NPR). This differential mechanism of action reduces the arterial vasodilating properties, while retaining the cardiac unloading and aldosterone inhibiting actions of the NPR-A receptor in addition to the direct anti-remodeling actions of the NPR-B receptor. Our objective is to determine the effects of 3 weeks of sustained delivery of CD-NP via a single subcutaneous (SQ) injection of a fully biodegradable in-situ polymer precipitation delivery system (Gel system) in a model of experimental myocardial infarction (MI).
