A Phase Ib Study of NVX-508 in Sickle Cell Disease

Summary

This Phase 1b study in adults with sickle cell disease (SCD) in steady-state (non-acutely ill) aims to evaluate safety and toxicity of NVX-508 in a multi-dosing paradigm as well as to determine the maximum tolerated dose (MTD) in this population. The information gained from this study will be used in making decisions about the appropriate dose(s) and dosing schedule in future multicenter studies of the efficacy of NVX-508 in the treatment of vaso-occlusive episodes (VOE).
