NCT05245734

Brief 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.

Study Arms (1)

Main group

EXPERIMENTAL

Patients receive two prophylactic doses of the Human Anti-D (rh) immunoglobulin at a dose of 300 mcg - at 28 weeks of gestation and within 72 hours after delivery. Patients receive the second dose only in the case of the birth of an Rh-positive child. Before and after each injection of the drug, blood will be taken to control the level of anti-Rh0 (D) antibodies. after the last injection of the drug, blood samples are taken after 3 and 6 months to assess sensitization to the Rh antigen. 15 participants from the Main group are formed the "Pharmacokinetics" subgroup for additional blood samples taking, to determine the pharmacokinetic parameters

Drug: Human Anti-D (rh) immunoglobulin

Interventions

prevention of Rh-sensitization in pregnant women in the antenatal and postnatal period in routine clinical practice. The study drug is administered twice at a dose of 300 mcg - at 28 weeks of gestation and within 72 hours after delivery.

Also known as: Rhesoglobin

  • severe thrombocytopenia and other hemostatic disorders;
  • life-threatening conditions and / or complications that require intensive care / surgery, the presence of any other bleeding at the time of screening;
  • Rh-negative fetus;
  • any other concomitant decompensated diseases or acute conditions, the presence of which, according to the researcher, can significantly affect the study results;
  • participation in any other clinical trial in the last 3 months and throughout the study.
  • Subgroup "Pharmacokinetics" (patients included in the additional study of some pharmacokinetic parameters):
  • any previous disease or intervention that, according to the researcher, may affect the pharmacokinetics of the study drug, in particular, organ and bone marrow transplantation, cancers;
  • presence of HIV, hepatitis B, or C viruses;
