NCT05041426
This is an interventional, open-label, single center, pilot study with historical controls to test the efficacy of letermovir (LET) for the prevention of CMV infection and disease in adult lung transplant recipients (LTRs) with idiopathic pulmonary fibrosis (IPF).
NCT07488481
Donor organs often carry latent Cytomegalovirus (CMV) infection that may be transmitted to the recipient. The goal of this clinical trial is to determine the safety of SYN002 treatment during Ex-Vivo Organ Perfusion (EVOP) in clinical kidney transplantation. Donor kidneys will be treated on the EVOP system with SYN002 in order to decrease the burden of latent CMV in the organ and mitigate the transmission of cytomegalovirus (CMV).
NCT06439342
The main aim of this study is to learn how safe maribavir is in Chinese adults who have undergone hematopoietic stem cell or organ transplantation and have a cytomegalovirus (CMV) infection and how well they tolerate treatment with maribavir. Other aims are to see how effective maribavir is in treating CMV infection and getting rid of the symptoms, the recurrence rate of CMV infection after treatment with maribavir and if the treatment is required again. Researchers will also check for changes (mutations) occurring in the virus which may cause treatment with maribavir to no longer work well or to not work at all (resistance to maribavir). The participants will be treated with maribavir for 8 weeks. During the study, participants will visit their study clinic 18 times.
NCT07235683
The primary objective of the CLEAR-CMV trial is to evaluate the efficacy of letermovir therapy plus standard of care (SOC) antiviral compared to SOC plus placebo in achieving clearance of CMV viremia by week 3 in lung transplant recipients with active CMV infection.
NCT07096453
The purpose of this study is to study how CMVIG interacts with the body and to see if it might work to prevent kidney transplant patients from becoming infected with CMV.
NCT06853184
This study is a randomized, open-label, active comparator-controlled, dose-ranging trial of the efficacy and safety of IV artesunate in combination with IV GCV or oral VGCV and SOC treatment compared to GCV or VGCV monotherapy and SOC treatment in SOT recipients with clinically significant CMV infection.
NCT06615921
The main aim of this study is to check how effective the treatment with Maribavir has been to remove the CMV viruses from the blood of an adult person with CMV infection after a transplant. Other aims are to learn more about how maribavir is used in normal clinical routine, study the profiles of adults treated with maribavir, and what other treatments have been given, and describe healthcare resources used for CMV management. Only data already available in the medical records of the participants will be reviewed and collected during this study.
NCT06453460
This is a phase 2, prospective cohort clinical trial evaluating the utilization of CMV T Cell Immunity Panel (CMV-TCIP) assay to guide the duration of primary CMV prophylaxis in CMV-seropositive recipients of allogeneic stem cell transplant or recipients receiving a stem cell graft from a CMV serology positive donor.
NCT01945814
In this study, investigators are trying to see if infusion of T cells (called CTLs) will prevent or treat cytomegalovirus (CMV), Epstein Barr Virus (EBV) and adenovirus (AdV) reactivation or infection. Patients with blood cell cancer, other blood disease or a genetic disease may receive a stem cell transplant. After receiving transplant, they are at risk of infections until a new immune system to fight infections grows from the cord blood cells. In this study, investigators are trying to give special cells called T cells. These cells will try to fight viruses that can cause infection. Investigators will test to see if blood cells from donor that have been grown in a special way, can prevent patients from getting an infection. EBV, AdV and CMV are viruses that can cause serious life-threatening infections in patients who have weak immune systems after transplant. T lymphocytes can kill viral cells but normally there are not enough of them to kill all the virus infected cells after transplant. Some researcher have taken T cells from a person's blood, grown more of them in the laboratory and then given them back to the person during a viral infection after a bone marrow transplant. Some of these studies have shown a positive therapeutic effect in patients receiving the CTLs after a viral infection in the post-transplant period. Investigators will grow these cells from donor in the laboratory in a way that will train them to recognize and remove viruses when the T cells are given after a transplant. Since most donors have previously been infected with EBV, CMV, and adenovirus, investigators are able to use their T cells that remember these viruses to grow the CTLs. However, they now also have a new way of growing CTLs from donors who have not been infected with CMV.
NCT06971913
This clinical trial will assess the efficacy and safety of low-dose interleukin-2 (IL-2) treatment in systemic lupus erythematosus (SLE) complicated with cytomegalovirus (CMV) viremia.
NCT05564598
Patients with moderate or severe CMV disease less than 21 days old who have a maternal donor who has a CMV response to the peptivators will be screened. All patients will receive treatment with valganciclovir or ganciclovir. There is a safety run in with treatment with CMV CTLs in cohort 1 and if found to be safe, will proceed to cohort 2 for randomization to receive antiviral therapy with or without CMV CTLs.

NCT04840199
This was an open-label, controlled study, conducted at US sites to evaluate the anti-inflammatory effectiveness of the study drug letermovir in adults with HIV and asymptomatic cytomegalovirus (CMV) who were on antiretroviral therapy (ART)-mediated suppression. Participants were randomly assigned to receive either letermovir once daily or no anti-CMV treatment, for 48 weeks. The primary hypothesis of this study was that letermovir would cause a greater reduction in plasma soluble receptor for tumor necrosis factor type II (sTNFRII) levels than no anti-CMV treatment at weeks 46/48.
NCT06793124
Observational, single-center, non-pharmacological, prospective study of adult patients affected by Inflammatory Bowel Disease (IBD) with an ongoing disease exacerbation requiring hospitalization
NCT03798301
The present trial will consist of the treatment of 20 pediatric and adult Hematopoietic Stem Cell Transplantation (HSCT) recipients or immunocompromised participants diagnosed with opportunistic Cytomegalovirus (CMV) infections with virus-specific, antigen-selected T-cells. CMV-specific T-cells will be isolated from donor leukapheresis products using the CliniMACS® Prodigy. Prior studies on transfer of CMV specific T-cells have been shown to be safe and efficacious in the treatment of CMV infections. The main trial objective is to evaluate the feasibility and safety of CMV-specific T-cell transfer in adult and pediatric participants suffering from CMV infections or reactivation following HSCT or due to other immunocompromised states (e.g.; primary immunodeficiency, cytotoxic therapy). Participants will be followed for one year.
NCT01877655
The purpose of the study was to evaluate the efficacy of ASP0113 compared with placebo as measured by a primary composite endpoint of overall mortality and CMV end organ disease (EOD) through 1 year post-transplant. Safety of ASP0113 in participants undergoing allogeneic HCT will also be evaluated.
NCT05446571
The investigators' hypothesis is that maternal treatment with Letermovir will inhibit fetal CMV replication better than Valaciclovir in infected fetuses and lead to a higher proportion of negative CMV PCR at birth in neonatal blood collected in the first day of life or in cord blood in case of termination of pregnancy (TOP). The main objective is to demonstrate that Letermovir administered to women carrying a CMV infected fetus following a maternal infection of the first trimester increases the proportion of neonates with a negative CMV PCR in neonatal blood collected in the first day of life or in cord blood in case of termination of pregnancy (TOP) compared to Valaciclovir. In each group , the proportion of asymptomatic neonates and the number and type of long-term sequelae at 2 years will also be assessed and compared.
NCT04021628
The cCHIPS study is a feasibility study for larger scale multi-centre studies and is designed as a single-centre observational cohort, longitudinal, natural history study. The overarching aim of this study is to evaluate the feasibility of performing larger scale, multi-centre studies to evaluate the relationship between CMV shedding in pregnancy with congenital CMV (cCMV). There is no randomisation involved in this study and all participants will perform the same study procedures and receive treatment as usual. The primary (main) objective is to evaluate the prevalence (percentage of occurrence) of CMV shedding in saliva, urine and vaginal secretions of CMV seropositive women throughout pregnancy. The secondary objectives are to evaluate the quantity of CMV shedding in saliva, urine and vaginal secretions of CMV seropositive women throughout pregnancy, to compare the prevalence and quantity of CMV shedding in CMV seropositive women between different sources of shedding (saliva, urine or vaginal secretions) and different gestational stages, to identify risk factors for CMV shedding in CMV seropositive pregnant women, to evaluate the acceptability of the study procedures to the participating pregnant women, to evaluate the proportion of women approached who are recruited into the study and who are completing the study, and to evaluate the relationship between CMV specific cell mediated immunity (a type of immune protection following exposure to CMV) and CMV shedding in CMV seropositive pregnant women. The tertiary objective is to compare the evaluation of CMV specific T cell immune responses (a type of CMV specific cell mediated immunity) between the two commercially available CMV-specific T cell immune response assays which are QuantiFERON-CMV and CMV-ELISPOT assays. This study will aim to recruit 200 pregnant women. This study will be undertaken in parallel with a separate study called RACE-FIT (REC reference number 18/SC/0360, IRAS ID 239977), which will have ethical approval to screen pregnant women with children less than 4 years of age booked for their antenatal care at St George's Hospital, London, identified during the antenatal combined screening bloods appointment or the antenatal booking appointment, for their CMV serology status on a sample of blood collected as part of the screening process. As part of the ethical approval sought for the RACE-FIT study and the cCHIPS study, the pregnant women screened and found to be CMV seronegative will be eligible for recruitment into the RACE-FIT study and those screened and found to be CMV seropositive will be eligible and approached for recruitment into the cCHIPS study. The cCHIPS study aim to recruit over a 6 month period. The study involves four visits (Visit 1, Visit 2, Visit 3, Visit 4) for each participant. The total study period for each participant will be between 6 to 8 months.
NCT06362720
The goal of this observational study is to compare the CMV infection and reactivation after allogeneic hematopoietic stem cell transplantation Between Standard Regimen, Methotrexate plus Cyclosporin A, and Post-transplant Cyclophosphamide-based Regimen. The main questions it aims to answer are: * How do CMV infection and reactivation differ between Allo-SCT patients who received a standard regimen versus those who received a Post-transplant Cyclophosphamide-based regimen? * progression-free survival, Median overall survival, cumulative incidence of relapse, non-relapsed mortality (NRM) and GvHD at 2 years after Allo-SCT * The impact of CMV infection and CMV reactivation on progression-free survival, overall survival, and NRM * Averse events of GVHD prophylaxis medication Participants will be collected the data of treatment and treatment response during transplant until 2 years after transplant from hospital medical record.
NCT03486834
This study evaluated the safety, tolerability, and efficacy of the cytomegalovirus (CMV) vaccine (V160) administered in a 2-dose or 3-dose regimen to healthy seronegative women 16 to 35 years of age. Participants received blinded V160 on Day 1, Month 2, and Month 6 (3-dose regimen), V160 on Day 1 and Month 6 and placebo at Month 2 (2-dose regimen), or placebo on Day 1, Month 2, and Month 6, and were followed to approximately Month 24. The primary hypothesis of the study was that administration of a 3-dose regimen of V160 will reduce the incidence of primary CMV infection compared to placebo.
NCT05432778
CMV infection is the most prevalent infection after heart transplantation (HTX), occurring in up to 40-60% of the recipients. It most frequently occurs within the first 6 months after transplantation and commonly presents as an asymptomatic viral replication. Viral syndrome or tissue-invasive disease (gastroenteritis, pneumonitis, myocarditis or meningitis) are much less common. Even though CMV infection is generally treatable with virostatic therapy and/or CMV-specific immunoglobulins, direct effects of CMV infection (viral syndrome and tissue-invasive disease) and general and transplant-specific indirect effects of CMV infection have been associated with significant morbidity and mortality in HTX patient population, mainly due to graft loss, development of malignancies, or opportunistic infections. According to the latest consensus paper on CMV prophylaxis and treatment in solid organ transplant recipients, valgancyclovir (or its active form gancyclovir) represents a virostatic therapy of choice for CMV prophylaxis and treatment after HTX. However, valgancyclovir has an array of side effects including hematological (leukopenia, neutropenia, anemia, thrombocytopenia), neurologic (headache, insomnia), gastrointestinal (decreased appetite, diarrhea, vomiting and dyspepsia) and psychiatric (depression) disorders. These can either expose HTX patients to additional complications (e.g. leukopenia and/or neutropenia can result in systemic fungal infections), decrease patients' quality of life, or mandate a decrease in valgancyclovir dose, which exposes patients to an increased risk for CMV reactivation. Recently, letermovir (a novel CMV viral terminase inhibitor), was approved for CMV prophylaxis in allogeneic bone marrow transplant recipients as the placebo-controlled study showed that significantly less patients, treated with letermovir, developed CMV disease (37% vs. 60%; P\<0.001) and there was also a trend towards lower all-cause mortality. Data on bone marrow transplant recipients additionally suggest that letermovir is generally well tolerated with side effects limited to mild gastrointestinal symptoms (diarrhea, nausea). Importantly, myelosuppresive side effects of letermovir occur very rarely. Some encouraging data does exist on the use of letermovir in kidney transplant recipients, where a recently published proof-of-concept trial (N=27) suggested comparable safety and efficacy of leteremovir (N=18) and valgancyclovir (N=9): both treatment regimens resulted in similar time-course of viral load reduction and viral clearance and were well tolerated in terms of adverse events. Currently, a Phase III clinical trial is ongoing in renal transplant recipients (Clinicaltrials.gov: NCT03443869) to confirm this pilot data. However, to date, there is no published data on the use of letermovir in patients after HTX. Based on the results in kidney transplantation, the aim of this pilot study is thus to evaluate the effects of letermovir-based CMV prophylaxis in heart transplant recipients. The primary objective of the study is to investigate the efficacy of letermovir-based CMV prophylaxis in patients after heart transplantation. The secondary objectives of the study are: * to investigate the tolerability of letermovir-based CMV prophylaxis in patients after heart transplantation. * to explore the potential correlation between letermovir-based CMV prophylaxis and restitution of cell-regulated immunity in patients after heart transplantation.
