Summary

The hypothesis of this trial is that the test drug (KamRho-D - T) is not inferior to the

comparator drug (Rhophylac - C) for immunization of Rh negative mothers at risk of

sensitization. The primary aim is to evaluate the clinical non-inferiority of the test drug

(KamRho-D - Panamerican) compared to the comparator drug (Rhophylac - CSL Behring) after

passive immunization in Rh-negative mothers, negative indirect Coombs, whose baby is Rh positive, through the incidence of non positivization of the indirect Coombs test 06 months after delivery. The secondary objective is to assess aspects of drug safety, such as: type, frequency and intensity of adverse events between groups.

Clinical Details

Official title: Phase III Study of the Evaluation of the Non-inferiority of Immunoglobulin Anti-RhD KamRho-D (Panamerican) Compared to Rhopphylac (CSL Behring)in Postpartum Immunization of Rh-negative, Coombs Negative Women at Risk of Sensitization.

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Investigator), Primary Purpose: Prevention

Primary outcome: The primary endpoint will be the maintenance of the negative result for the indirect Coombs test 06 months after delivery, proving that the test drug and the comparator drug had the same ability to neutralize possible fetal red blood cells.

Secondary outcome: Incidence, intensity, type and frequence of adverse event.
