Primary

MeasureTime frame
Main Objective: Efficacy objective: To assess the efficacy of IMMUNORHO in the prevention of Rh(D) isoimmunization in Rh(D) negative women pregnant with a Rh(D) positive foetus (including D, Dweak and Dpartial ), as measured by the incidence rate of anti-D antibodies at 24 weeks (corresponding to the 6 months timepoint in the EMA guideline) after last treatment administered;Secondary Objective: Secondary Efficacy objective: To assess the efficacy of IMMUNORHO in the prevention of Rh(D) isoimmunization in Rh(D) negative women pregnant with a Rh(D) positive foetus (including D, Dweak and Dpartial ), as measured by the incidence rate of anti-D antibodies at 12 weeks (corresponding to the 3 months timepoint in the EMA guideline) after last treatment administered Safety Objective: To assess the safety of IMMUNORHO in the prevention of Rh(D) isoimmunization in Rh(D) negative women pregnant with a Rh(D) positive foetus (including D, Dweak and Dpartial ) from Baseline visit to 24 weeks (corresponding to 6 months) after last treatment administered Pharmacokinetic Objective: To characterize the pharmacokinetics (PK) of anti-D immunoglobulin after IMMUNORHO administration in Rh(D) negative pregnant women;Primary end point(s): Primary Efficacy Endpoints Incidence rate of anti-D antibodies evaluated at 24 weeks (corresponding to the 6 months timepoint in the EMA guideline) after treatment (last dose received). ;Timepoint(s) of evaluation of this end point: 24 weeks after treatment
