Active clinical trials for "Cytomegalovirus Infections"

Study Phase: IV Study Type: Open-label, multicenter, randomised clinical trial with two arms stratified for an intensified immunosuppressive regimen in patients at high risk for acute rejection. Study Description: 148 kidney transplant recipients at risk for CMV disease were randomized and treated with ganciclovir capsules for 3 months (Group A, prophylaxis, N=74) or received ganciclovir IV only in case of proven CMV viral load (Group B, preemptive therapy, N=74). Initially, a 2 months follow up was planned in this trial. However, the study group decided to offer a longterm follow up to all patients and amended the protocol, respectively. The aim of the study was to identify the most efficacious way to prevent renal transplant recipients from CMV disease and to find out, if one of these two strategies may increase graft or patient survival. Therefore, both wellknown approaches of CMV prevention were compared in two study groups: Prophylaxis (Group A): Oral primary prophylaxis with ganciclovir capsules was started directly after transplantation and performed until day 90. In case of CMV infection (proven CMV viral load) or symptomatic CMV disease, treatment with ganciclovir IV was initiated. Preemptive Therapy (Group B): No oral primary prophylaxis was given. Treatment with ganciclovir IV was given to patients with proven CMV viral load (CMV infection or CMV disease) only.

Cytomegalovirus (CMV) infection is a common opportunistic infection (OI) in HIV patients. The purpose of this study is to find out whether valganciclovir, an antiviral approved by the FDA for the treatment of CMV in the eye, is safe and effective in preventing CMV organ damage in people with HIV.

The main objective of this study is to evaluate the safety, reactogenicity, and immunogenicity of the mRNA-1647 vaccine administered according to a 3-study injection schedule in healthy cytomegalovirus (CMV)-seronegative and CMV-seropositive Japanese adults 18 to 40 years of age in the United States.

The purpose of the study is to assess the safety and tolerability of a 3-dose regimen of V160 administered by intramuscular (IM) injection in healthy Japanese male participants by cytomegalovirus (CMV) serostatus. There is no formal hypothesis.

Cytomegalovirus (CMV) is the most common opportunistic viral pathogen in solid organ transplant receptors (SOTR). In Mexico, the experience using generic immunosuppressants have been demonstrated a wide variation in the pharmacokinetic parameters between generic and innovative formulation, resulting in a suboptimal absorption of the drug and reaching infratherapeutic trough levels in blood. In this study the investigators will compare the pharmacokinetic parameters of innovative and generic valganciclovir in renal transplant recipients.

This open-label, single arm study will evaluate the tolerability and efficacy of Valcyte (valganciclovir) in the prevention of cytomegalovirus disease in pediatric renal transplant recipients. After transplantation, patients (aged 4 months to 16 years) will receive Valcyte orally daily for up to 200 days post-transplant and will be followed for 52 weeks post-transplantation.

The purpose of this study is to evaluate the potential clinical benefit of pre-emptive cytomegalovirus (CMV)-specific adoptive cellular therapy following T cell depleted allogeneic hematopoietic stem cell transplantation (HSCT) for reducing recurrent CMV reactivation.

The aim of this prospective, randomized study is to assess a subject's immunological status against hCMV before kidney transplantation by an hCMV-specific interferon (INF)-γ ELISPOT technique confirming previous results and establishing their statistical validity in order to determine whether this test could be used routinely in clinical practice to assess the risk of developing hCMV infection after renal transplantation and, ultimately, identify the most effective individual antiviral therapeutic strategy against hCMV.

The purpose of this research study is to investigate whether or not oral maribavir is safe and effective compared to oral ganciclovir for preventing CMV disease when administered for up to 14 weeks in patients who have had a liver transplant.

This 2 arm study will compare the efficacy of 100 days of Valcyte (900mg po daily) prophylaxis with that of no prophylaxis, under the condition of pre-emptive therapy of active CMV infection, in CMV positive renal transplant recipients. The influence of the two prevention concepts on the occurrence of direct and indirect effects of active CMV infections will be compared. The anticipated time on study treatment is 3 months-1 year, and the target sample size is 100-500 individuals.
