Pharmacokinetics and Safety of Roledumab in RhD-negative Pregnant Women Carrying an RhD-positive Foetus
Pharmacokinetics and Safety of Roledumab, a Fully Human Recombinant Monoclonal Anti-RhD Antibody, in RhD-negative Pregnant Woman Carrying an RhD-positive Foetus: a Phase IIb, Multicenter, Open-label Study
The aim of this study is to assess the pharmacokinetic profile of Roledumab 300μg IM / IV in RhD-negative pregnant women carrying an RhD-positive foetus.
To assess the safety of Roledumab in RhD-negative pregnant women and in RhD-positive fetus and newborns.
In addition the efficacy of Roledumab 300μg IM and IV to prevent RhD alloimmunisation in RhD-negative pregnant women carrying an RhD-positive fetus and the immunogenicity of Roledumab will be assessed.

Description
Inclusion Criteria:
- Signed and dated informed consent form provided by the subject prior to proceeding with any study-related procedure,
- At least 18 years old,
- Pregnancy between 12 and 27 weeks gestational age as confirmed by early ultrasound,
- Pregnant RhD-negative woman carrying an RhD-positive fetus confirmed by a non-invasive fetal RhD genotyping test,
- Negative serology: HIV (1 and 2), hepatitis C and hepatitis B, except for positive results due to vaccinations,
- Covered by healthcare insurance in accordance with local requirements.
Exclusion Criteria:
- RhD allo-immunized subject,
- Positive for ADA test,
- Multiple fetuses,

- Prior administration of anti-RhD immunoglobulin during the current pregnancy,
- Known clinically relevant maternal or fetal abnormality (e.g., as determined by ultrasound or genetic testing), such as placenta previa,
- History of anaphylactic or severe systemic reaction to immunoglobulin of any origin,
- Current diagnosis of an immune disease which by itself or its treatment could impair the safety and/or efficacy evaluation of Roledumab in this study. These diseases are: All immune deficiencies, particularly those requiring IV-Ig supplementation or other systemic treatment / connective tissue and autoimmune diseases (e.g., systemic lupus erythematosus, antiphospholipid syndrome, Sjögren's syndrome, rheumatoid arthritis, ankylosing spondylarthritis) requiring systemic immunosuppressive treatment / allergic and inflammatory diseases requiring systemic immunosuppressive treatment,
- Clinically significant medical history contraindicating the participation in the study according to the judgment of the Investigator or Sponsor,
- Clinically significant laboratory (hematology, blood chemistry, or urinalysis) parameters,
- For the IM arm only, subject with coagulation disorders contraindicating intramuscular injection (patient will still be considered for the IV arm),

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Roledumab Open-label IM
- Planned antenatal prophylaxis: A single dose of 300 µg IM of Roledumab at 28 or 29 weeks of gestation. - Antenatal prophylaxis following sensitizing events: One or more dose(s) of 300μg IM anti-RhD antibodies (Rhophylac or Roledumab) based on the Kleihauer-test as soon as possible and no later than 72 hours after event occurrence. - Postnatal prophylaxis: Roledumab should be administered to the mother as soon as possible within 72 hours of delivery of an RhD positive infant. The postnatal dose must still be given even when antenatal prophylaxis has been administered. Before Roledumab 300μg IM postnatal administration, a Kleihauer-Betke test will be performed on maternal blood sample taken no earlier than 30 min after delivery in order to determine the volume of foetomaternal hemorrhage (FMH). |

Experimental: Roledumab Open-label IV
- Planned antenatal prophylaxis: A single dose of 300 µg IV of Roledumab at 28 or 29 weeks of gestation. - Antenatal prophylaxis following sensitizing events: One or more dose(s) of 300μg IV anti-RhD antibodies (Rhophylac or Roledumab) based on the Kleihauer-test as soon as possible and no later than 72 hours after event occurrence. - Postnatal prophylaxis: Roledumab should be administered to the mother as soon as possible within 72 hours of delivery of an RhD positive infant. The postnatal dose must still be given even when antenatal prophylaxis has been administered. Before Roledumab 300μg IV postnatal administration, a Kleihauer-Betke test will be performed on maternal blood sample taken no earlier than 30 min after delivery in order to determine the volume of foetomaternal hemorrhage (FMH). |
