SAN FRANCISCO, Oct. 14 /PRNewswire-FirstCall/ -- Nile Therapeutics, Inc. (Nasdaq: NLTX), today announced interim data from its multi-center, open-label Phase 2a clinical study of CD-NP, a novel chimeric natriuretic peptide, in patients hospitalized for acute heart failure.

-- Statistically significant reduction in pulmonary capillary wedge

pressure

-- Statistically significant increase in diuresis

-- Trend toward reduction in right atrial pressure

-- Trend toward increase in cardiac output

-- No hypotension

-- No change in serum creatinine

About the Study

The objective of the Phase 2a study is to assess hemodynamic and renal effects of CD-NP in patients with acute heart failure. In this dose escalation trial, stabilized acute heart failure patients receiving standard-of-care heart failure medications were administered an 8-hour infusion of CD-NP at 3 ng/kg/min (n=11), followed by a 14-hour washout period, and then an 8-hour infusion of CD-NP at 10 ng/kg/min (n=9).

Effects on Hemodynamics

Results from the first cohort of patients show a statistically significant reduction in pulmonary capillary wedge pressure (PCWP). Infusion with 3 ng/kg/min of CD-NP resulted in a statistically significant reduction of 2.9 mmHg relative to baseline at eight hours (p=0.02). Infusion of 10 ng/kg/min CD-NP following a washout period resulted in a further reduction of PCWP, which reached statistical significance at two hours after initiation (p=0.02). In patients who completed both doses of CD-NP, there was a statistically significant overall reduction in PCWP of 5.4 mmHg (p=0.002) from the initial baseline PCWP of 23.7 mmHg. The interim results also include an observed tre
