2009 Objectives

Nile is focused on very specific clinical and corporate objectives:

 

   

To complete the dosing of a 30 patient, placebo-controlled Phase 2b study in the 3rd quarter of 2009. This study is designed to provide additional clinical evidence that CD-NP enhances renal function. This finding would favorably differentiate CD-NP from other acute heart failure therapies.

 

   

Through financing, partnering or other strategic alternative, secure the resources necessary to continue development activities beyond the 30 patient Phase 2b study.

 

   

To start enrollment into the 330 patient double-blind, placebo-controlled Phase 2b acute heart failure Proof of Concept study.
