Under the terms of the agreement, Medtronic will fund and provide its drug-device expertise as Nile executes on its Phase I clinical trial to assess the pharmacokinetics and pharmacodynamics of cenderitide delivered through Medtronic diabetes pump technology. In the planned clinical trial, cenderitide will be delivered to heart failure patients for up to 24 hours through continuous subcutaneous infusion. Nile expects to complete the trial by the first quarter of 2012. Financial terms were not disclosed.

Following the Phase I study, Nile intends to initiate a larger Phase II double-blind, placebo-controlled, dose ranging study in patients admitted to the hospital for acute heart failure. The planned Phase II study will evaluate the endpoints of cardiac remodeling, renal function, re-hospitalization and mortality in patients following 90 days of continuous therapy via subcutaneous pump. The first 90 days following admission to the hospital is a critical time for heart failure patients who are known to have combined rates of re-admission and mortality as high as 50% during that period. Nile believes that the cardiac unloading and renal preserving properties of cenderitide could have a significant benefit to patients during a critical time in their recovery from acute heart failure.

Heart failure is the fastest-growing clinical cardiac disease in the U.S. according to the American Heart Association, affecting over 5 million Americans. Over 1 million patients in the U.S. each year are hospitalized with ADHF, an acute exacerbation of heart failure. This hospitalization rate is almost double the rate seen 15 years ago, and is the most frequent cause of hospital admission in the U.S. for patients older than 65 years, generating annual inpatient costs of more than $33 billion.

Nile Therapeutics, Inc. is a clinical-stage biopharmaceutical company that develops innovative products for the treatment of cardiovascular disease and other areas of unmet medical needs. Nile is initially focusing its efforts on developing its lead compound, cenderitide, a novel rationally designed chimeric peptide in clinical studies for the treatment of heart failure, and CU-NP, a novel rationally designed natriuretic peptide.
