Nile Therapeutics update on phase II CD-NP trial for acute heart failure

Nile Therapeutics, Inc. has announced that, in the course of reviewing the Investigational New Drug (IND) application materials that Nile submitted to the U.S. Food and Drug Administration (FDA) to support the initiation of the Company's Phase IIb clinical trial with CD-NP for the treatment of acute heart failure, the FDA has placed CD-NP on clinical hold.

In a letter sent to the Company this week and in a follow-up teleconference with the Company, the FDA requested additional data from the recently completed Phase IIa clinical trial and modifications to CD-NP's Investigator Brochure (IB). The Company is working diligently to respond in a timely manner and expects to be able to provide a complete response to the FDA's requests with recently finalized data from the Phase IIa clinical trial in acute heart failure patients.

CD-NP is a novel chimeric natriuretic peptide in clinical development for the treatment of acute heart failure. CD-NP was designed to have direct hemodynamic and renal activity to reduce symptoms of dyspnea, be diuretic and natriuretic and preserve or enhance renal function in heart failure patients. In addition to an initial indication for acute heart failure, CD-NP has potential utility in other indications which include preservation of cardiac function subsequent to acute myocardial infarction (AMI), and prevention of renal damage subsequent to cardiac surgery.
