Dose-finding Study of LFB-R593, A Monoclonal Anti-RhD Antibody, in Healthy RhD Negative Volunteers

A Phase II, Open-label, Randomised, Dose-finding Study to Compare the Efficacy (in Terms of Clearance of RhD-positive RBCs) and Safety of LFB-R593, a Monoclonal Anti-RhD Antibody vs a Polyclonal Anti-RhD Immunoglobulin in Healthy RhD Negative Volunteers

This phase II study is designed to demonstrate the ability of LFB-R593 to effectively eliminate exogenously-administered RhD-positive red blood cells from the circulation of an RhD-negative individual, thereby preventing RhD-alloimmunisation.
