Brief Summary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Cytomegalovirus (CMV) is a very common virus and in the same family as the viruses that cause herpes, chickenpox, and mononucleosis. Most people become infected with the virus when they come in direct contact with an infected person's bodily fluids. People with a normal immune system who become infected with CMV can have no symptoms or have symptoms similar to the common cold; people with a normal immune system rarely have any major complications from the virus. Once someone is infected with CMV, the virus remains inactive, or dormant, in the body for life; sometimes the virus can become active again and cause symptoms or severe disease, especially in people who are sick or have a weak immune system.
Individuals who receive an organ transplant are more likely to get an active CMV infection because of the medications required to prevent the immune system from attacking the transplanted organ. The immune system might recognize the organ transplant as a threat because it is not made of the same cells as the rest of the body. Anti-rejection medications help to reduce the immune system from attacking and damaging a new organ but also make it harder to fight off CMV and other infections. CMV is one of the most common infections after transplant.
Transplant teams test for CMV when someone is listed for an organ transplant and right before surgery. Both donors and recipients are tested for a CMV antibody which determines if someone has ever been infected with CMV. An antibody is created by the immune system and helps fight dangerous invaders like bacteria, fungus, or a virus, like CMV. People develop an antibody if the virus has been present in their body at any point in their life. CMV is so common that healthy people who test positive for CMV can still be organ donors; about half of all American adults have previous CMV infections.
The transplant team looks at the CMV antibody test results from both a donor and recipient at the time of the transplant surgery to determine the level of possible risk for CMV disease occurring in the recipient. Below is information regarding the level of potential risk to the recipient based on the presence (+) or absence (-) of antibodies. Other factors can influence someone's risk of CMV disease after transplant and can include age (of donor and recipient), other health problems, type and dosage of certain anti-rejection medications taken after transplant, and symptoms of transplant rejection.
Risk Levels Lowest (D-/R-): Neither the donor nor the recipient have been infected with CMV. This match presents the lowest risk of CMV disease to the recipient.
Moderate (D-/R+ or R+/R+): When the recipient is positive for the antibody, they have some immunity, or protection, to the virus so they face a moderate risk for CMV disease regardless of their donor's CMV status. These mismatches present a moderate risk for CMV disease.
Highest (D+/R-): The highest risk for CMV disease occurs when a donor is positive for the antibody, but the recipient is negative. In this situation, the virus is present in the donor's body, but the recipient has no antibodies or immunity/protection against the virus. This mismatch presents the highest risk for CMV disease.
When someone has CMV before transplant, there is a risk the virus will reactivate after transplant when the immune system is suppressed. These patients have some protection against the virus because there are antibodies, or immunity, present in the body which helps reduce the risk for severe CMV disease. If a transplant recipient has never had CMV but receives an organ from someone who had CMV there is no natural protection against the virus and those individuals face the highest risk for CMV disease.
CMV disease may cause flu-like symptoms like fever, chills, fatigue, and muscle aches. CMV can also cause infection in different types of tissues and other types of CMV disease like:
Pneumonia (a lung infection that causes fever, cough, labored breathing) Gastrointestinal disease (indigestion, nausea, vomiting, abdominal pain, bloating, diarrhea) Hepatitis (inflammation of the liver) Central nervous system disease (infection of the brain or spinal cord causing weakness, decreased memory, confusion) Retinitis (inflammation of the retina, a part of the eye, which impact vision) Organ dysfunction-CMV can impact the function of other organs and affect a transplanted organ Organ rejection Death
CMV disease usually occurs in the first few months after transplant when anti-rejection medications are taken in higher doses and the immune system is at its weakest. During this high-risk period, transplant recipients at a moderate or high CMV risk are prescribed an antiviral medication, valganciclovir. Prophylactic, or preventive, treatment with valganciclovir greatly reduces the risk for CMV disease but some recipients still develop late CMV disease, which occurs more than 100 days after transplant. The risk for late CMV disease is highest in individuals who did not have a CMV infection (R-) before transplant but received an organ from someone who had CMV (D+). This mismatch is written as D+R-.
The length of time someone is on prophylactic treatment after organ transplant depends on the type of organ they receive and their risk level. D+R- liver transplant recipients are often prescribed valganciclovir for 3 months while D+R- kidney transplant recipients often take valganciclovir for 6 months. Following valganciclovir treatment, some recipients may have their blood tested every 1 to 2 weeks for 3 months to monitor how much CMV is the body; this test, called a CMV PCR test looks for the DNA of the virus and can help the transplant team assess the recipient's risk for CMV disease, diagnose CMV quickly, and monitor treatment effectiveness and development of antiviral resistance.
This research is being done to explore if the risk of late CMV disease following a D+R- a liver, kidney, or simultaneous liver-kidney transplant can be further reduced with CytoGam® infusions after the standardly prescribed prophylactic antiviral medications.
CytoGam® is an intravenous immunoglobulin or IVIG. Immunoglobulin is another name for an antibody and helps the body fight infection; intravenous immunoglobulin is made with collected antibodies from healthy donors and is like a blood transfusion from donated blood. A CytoGam® infusion delivers immunoglobulin, or antibodies, specific to CMV to help strength the immune system's natural defenses.
CytoGam® is approved by the U.S. Food and Drug Administration (FDA) for the prophylaxis, or prevention, of CMV disease associated with transplantation of kidney, lung, liver pancreas, and heart, but CytoGam® is not approved by the FDA to be administered after antiviral prophylaxis to prevent CMV disease or reduce CMV severity.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Arm A: CytoGam®
Participants assigned to receive CytoGam® will receive an infusion once a month for three months at their study site. The infusion will be completed over an average of about 4 hours; these three visits will last about 5 hours. During these study staff will review concomitant medications and adverse events. Participants will be asked to have blood taken at infusion visits and 2 weeks after an infusion visit to check the level of CMV DNA in their blood.
Cytomegalovirus Immune Globulin Intravenous (Human) monthly for three months
The interventional arm will receive Cytomegalovirus Immune Globulin Intravenous (Human) monthly for three months as (150 mg/kg) for 3 consecutive months (Days 0, 28 and 56 +/- 3 days). The non-interventional arm will not receive any intervention.
Arm B: Standard of Care
Participants assigned to Arm B, will be asked to complete a telephone call visit once a month. During these visits, a member of study staff will review concomitant medications and adverse events. Participants will be asked to have their blood taken every two weeks to check the level of CMV DNA.
