Clinical Efficacy of Postpartum Immunization of Rh and Coombs Negative Women With Sensitization Risk.

November 1, 2022 updated by: Azidus Brasil

Evaluation of the Clinic Efficacy of Immunoglobulin Anti-RhD KamRho-D® (Panamerican) in Postpartum Immunization of Rh and Coombs Negative Women at Sensitization Risk.

This a open, prospective, multicenter, single-arm, phase III study for clinical assessment of anti-Rh immunoglobulin (KamRho-D®) in Rh and Coombs negative women with risk sensitization. The anti-Rh immunoglobulin is an immunobiological containing high concentration of specific antibodies against factor D and "neutralizes" D antigen present in the Rh-positive fetal red blood cells (Rh +), which passed into the bloodstream of Rh-negative pregnant women (Rh).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This a phase III study in which women participants with RH and Coombs negative will receive only one dose of 1500 IU anti-Rh immunoglobulin intramuscularly up to 72 hours post exposition (child-birth) and will be following until six months to verification of negative Coombs maintenance. Safety evaluation data will include report of all adverse events (including type, frequency, intensity, seriousness, severity and action taken related to the investigational product).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Negative result for coombs test up to six months after immunization
Time Frame: up to six months
Will be evaluated by proportion of participants that presented negative result for coombs test until six months after passive immunization with investigational product.
up to six months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Adverse Events Report
Time Frame: up to six months
Safety of human immunoglobulin anti-RhD will be verified through adverse events reported by participants throughout study. The adverse events will be classified about the type, frequency, intensity, seriousness, severity and relation to the study drug.
