Open-label, Multicenter, International Study of the Efficacy and Safety of the Drug Rhesoglobin (Human Anti-D (rh) Immunoglobulin) Manufactured by Biopharma Plasma LLC, Ukraine, in Pregnant Women in the Antenatal and Postnatal Period in Routine Clinical Practice for the Prevention of Rh Sensitization, With a Subgroup for Evaluation of Some Pharmacokinetic Parameters

Conditions
Summary
Rhesus conflict between mother and fetus is due to the different antigenic composition of erythrocytes. During the first pregnancy, sensitization of the mother to fetal erythrocytes rhesus D (RhD) antigens is formed. During the next pregnancy, fetal red blood cells are attacked by the mother's antibodies, and fetal/newborn hemolytic disease develops. The drug Rhesoglobin blocks the interaction of the fetal erythrocytes RhD antigen and the immune system of the mother and prevents the development of Rhesus sensitization.
