Active clinical trials for "Cytomegalovirus Infections"

The objectives of this study were: To demonstrate the efficacy/safety of a short therapeutic strategy of treatment of CMV infection/disease in SOT patients (kidney, liver and heart recipients) based on 21 days of treatment. To compare the exposure to ganciclovir, at steady state, after oral valganciclovir with respect to ganciclovir given intravenously (i.v.). Evaluate the security of this treatment with valganciclovir.

Patients have a type of blood cell cancer, other blood disease or a genetic disease for which they will receive a stem cell transplant. The donor of the stem cells will be either a brother or sister or another relative or a closely matched unrelated donor. We are asking patients to participate in this study which tests if blood cells from the donor that have been grown in a special way, can prevent the patients from getting an infection with a virus called Cytomegalovirus or CMV. CMV is a virus that can cause serious infections in patients with suppressed immune systems. It usually affects the lungs and can cause a very serious pneumonia, but it can also affect the intestinal tract, the liver and the eyes. Approximately 2/3 of normal people harbor this virus in their body. In healthy people CMV rarely causes any problems because the immune system can keep it under control. If the patient and/or their donor is positive for CMV, they are at risk of developing CMV disease while the patients immune system is weak post transplant. Usually, this risk is highest during the first 3-4 months after the transplant. CMV disease can be prevented during this time in most people by using drugs that can kill the virus such as Ganciclovir, Foscarnet, or Cidofovir . However, these medications have many side effects and have to be given daily by vein for approximately 4-5 months after transplant. One of the side effects is that it takes the new immune system much longer to develop an effective defense against the virus. Therefore, once the medicines are stopped, the patients still have a chance to develop CMV disease. We want to see if we can use a kind of white blood cell called T cells that we have grown from the stem cell donor instead of the regular treatment with Ganciclovir or Foscarnet to prevent CMV from "flaring up". These cells have been trained to attack CMV virus infected cells. We will grow these T cells from blood taken from the donor before the patients transplant. These cells are called CMV-specific cytotoxic T-lymphocytes or CMV CTL, and they will be given to the patient around 30 days after their transplant. We have used this sort of therapy to treat a different virus which can cause problems after transplant called Epstein Barr Virus (EBV). Doctors at other places have used similar T cells to treat or prevent CMV infections after transplant and have not seen any significant problems. These CMV specific cytotoxic T cells are an investigational product not approved by the Food and Drug Administration.

OBJECTIVES: I. Evaluate the safety, tolerance, and potential efficacy of 3 doses of human anti-cytomegalovirus (CMV) monoclonal antibody SDZ MSL-109 (MOAB MSL-109) in the treatment of newborns with congenital CMV infection and no central nervous system disease. II. Determine the relationship between plasma concentrations of MOAB MSL-109 and therapeutic outcome. III. Determine whether MOAB MSL-109 influences the antibody response and clearance of virus from the urine.

To determine a clinically safe and effective dose of intravitreally injected ISIS 2922 and to compare the safety and efficacy of immediate versus delayed treatment in AIDS patients with previously untreated, peripheral cytomegalovirus ( CMV ) retinitis.

To evaluate the efficacy of oral ganciclovir in preventing progression to cytomegalovirus (CMV) disease (e.g., CMV retinitis, gastrointestinal CMV disease) in CMV-infected people with HIV infection and CD4 lymphocyte counts <= 100 cells/mm3. To evaluate the efficacy of this drug in reducing morbidity associated with coinfection by both CMV and HIV.

To determine whether there is a pharmacokinetic drug interaction between oral ganciclovir and oral zidovudine (AZT) and between oral ganciclovir and oral didanosine (ddI). To determine whether concurrent administration of probenecid affects the pharmacokinetics of oral ganciclovir. To obtain data on the short-term safety of oral ganciclovir administered concurrently with AZT, ddI, or probenecid in HIV-positive patients.

This is a single cente, single arm, open-label, phase I study to evaluate the safety and effectiveness of CMV-TCR-T cell immunotherapy in treating CMV virus infection after HSCT.

To compare the efficacy of oral brincidofovir (BCV) to valganciclovir (vGCV) for the prevention of cytomegalovirus (CMV) disease in kidney transplant allograft recipients who are CMV seronegative pretransplant and received a kidney from a CMV seropositive donor

Cytomegalovirus (CMV) infection is the most frequent opportunistic viral infection after transplantation. It is associated with an increased incidence of acute rejection and lower graft and patient survivals. The goal of this study is to demonstrate that an immunosuppressive regimen associating everolimus and reduced dose of cyclosporine A can prevent acute rejection episodes as efficiently as standard regimen but also efficiently reduce the incidence of CMV infection at 6 months post-transplantation.

This is an international, multi-center, double-blind, placebo-controlled evaluation valganciclovir treatment for up to 54 children (up to 4 years of age) with virologically-confirmed congenital CMV infection and hearing loss. Subject participation will be over a six-month period and study subjects will be stratified according to age. The primary objective is to assess whether a six-week course of oral valganciclovir can stabilize the hearing of children with congenital CMV infection who present with hearing loss.
