RhoGAM® and MICRhoGAM® Rho(D) Immune Globulin (Human) are sterile solutions containing IgG anti-D (anti-Rh) for use in preventing Rh immunization.
The indications are the following:
PREGNANCY AND OTHER OBSTETRICAL CONDITIONS IN RH-NEGATIVE WOMEN, UNLESS THE FATHER OR BABY ARE CONCLUSIVELY RH NEGATIVE
Pregnancy/delivery of an Rh-positive baby irrespective of the ABO groups of the mother and baby
Abortion/threatened abortion at any stage of gestation
Antepartum fetal-maternal hemorrhage (suspected or proven) resulting from antepartum hemorrhage (e.g., placenta previa), amniocentesis, chorionic villus sampling, percutaneous umbilical blood sampling, other obstetrical manipulative procedure (e.g., version) or abdominal trauma
Transfusion of Rh incompatible blood or blood products
Prevention of Rh immunization in any Rh-negative person after incompatible transfusion of Rh-positive blood or blood products (e.g., red cells, platelet concentrates, granulocyte concentrates)
Published Studies Related to Rhogam (IgG Anti-D)
Dual inhibition of the epidermal growth factor receptor with cetuximab, an IgG1 monoclonal antibody, and gefitinib, a tyrosine kinase inhibitor, in patients with refractory non-small cell lung cancer (NSCLC): a phase I study. [2008.03]
PURPOSE: To determine the optimal doses of the antiepidermal growth factor receptor (anti-EGFR) monoclonal antibody cetuximab and the EGFR tyrosine kinase inhibitor gefitinib when administered as a combination for patients with advanced/metastatic non-small cell lung cancer (NSCLC) previously treated with platinum-based chemotherapy... CONCLUSION: Dual EGFR inhibition with cetuximab and gefitinib is feasible; the combination can be safely administered and may have modest activity in advanced/metastatic NSCLC. Cetuximab 250 mg/m(2) weekly IV and gefitinib 250 mg/d PO is the recommended phase II dose, although the potential for late-onset hypomagnesemia warrants close monitoring of patients receiving this combined dosage.
Kinetics of the immune response following pneumococcal PD conjugate vaccination. [2007.03.01]
Primary vaccination with pneumococcal protein D conjugate vaccine in the first year of life induced clear ELISA and OPA responses, which varied considerably for the different serotypes. Antibody levels declined following primary vaccination but were restored (except for serotype 3) to above post-primary levels by booster vaccination in the second year of life.
Pharmacokinetics of anti-D IgG in pregnant RhD-negative women. [2003.01]
OBJECTIVE: To assess the pharmacokinetics of anti-D IgG in pregnant Rhesus D-negative women after intramuscular and intravenous administration of 300 microg of Rhophylac... CONCLUSIONS: The serum concentrations of anti-D IgG measured after administration of Rhophylac were very similar to those obtained with 300 microg of a different anti-D immunoglobulin product.
IgG-mediated immunosuppression is not dependent on erythrocyte clearance or immunological evasion: implications for the mechanism of action of anti-D in the prevention of haemolytic disease of the newborn? [2007.10]
Haemolytic disease of the newborn (HDN) can be prevented by the passive administration of anti-D to the mother... These data indicate that removal of opsonized erythrocytes by phagocytic cells does not prevent their immunological recognition and suggest that antigen clearance may not be the predominant mechanism of anti-erythrocyte action in downregulating the humoral immune response.
Binding kinetics, uptake and intracellular accumulation of F105, an anti-gp120 human IgG1kappa monoclonal antibody, in HIV-1 infected cells. [2007.01]
The use of targeting moieties is a new and exciting field of scientific research for facilitating the specific delivery of therapeutic agents in HIV-infected patients. The interaction of a potential targeting moiety with its ligand is a crucial factor in the evaluation of a targeted approach for chemotherapeutic intervention.
Clinical Trials Related to Rhogam (IgG Anti-D)
A Study to Find How Safe and Effective GAMMAPLEX® is in Subjects With Chronic Idiopathic Thrombocytopenic Purpura (ITP) [Completed]
To determine if GAMMAPLEX raises the platelet count of subjects with chronic ITP to a
threshold of 50 x 109/L, similar to that of published response >60%. Also to assess the
safety of GAMMAPLEX and determine if platelet counts are maintained at 50 x 109/L in
subjects with chronic ITP for.
Trial of the Efficacy of Intravenous Immunoglobulin for Treating Women With Unexplained Secondary Recurrent Miscarriage [Completed]
The investigators want to test whether infusions of intravenous immunoglobulin - a blood
product known to modify immune responses - in early pregnancy will increase the chance of a
subsequent live birth in women with three or more miscarriages after a birth and a total of
at least four miscarriages. This will be done in a trial where 82 patients will be randomly
allocated to infusions with intravenous immunoglobulin or placebo during pregnancy.
Investigating the Role of Early Intravenous Immunoglobulin Treatment for Children With Encephalitis [Not yet recruiting]
This is a phase III multi-centre randomised, double blind, placebo controlled trial to
assess the role of intravenous immunoglobulin in the treatment of children with
encephalitis. The primary objective is to find out whether early use of IVIG treatment
improves neurological outcomes of children with encephalitis.
308 children with encephalitis, aged 6 weeks to 16 years will be recruited in 30 hospitals
in the United Kingdom. Participants will be randomised to receive two doses of IVIG or
matching placebo in addition to other standard treatments, within the first five days of
Each participant will be followed up for 12 months. During this period, information on
clinical, radiological and laboratory investigations will be collected. Neurological
outcomes will be assessed by the use of questionnaires at 6 and 12 months, and a
neuropsychological assessment at 12 months.
A Double-Blind, Placebo Controlled Study of Intravenous Immunoglobulin for HIV-Associated Myelopathy [Recruiting]
The purpose of this study is to determine whether Intravenous Immunoglobulin (IVIG) is an
effective treatment for HIV associated myelopathy.
Intravenous Immunoglobulins in Complex-regional Pain Syndrome [Not yet recruiting]
The purpose of this study is to determine whether intravenous immunoglobulins are effective
in the treatment of complex-regional pain syndrome.
