Open Label Trial of Oral Letermovir for CMV Prophylaxis in Thoracic Transplant Recipients

Cytomegalovirus InfectionsTransplant-Related Disorder

Open label study to determine tolerability and efficacy of letermovir for CMV prophylaxis in heart and lung transplant recipients and compare it to the efficacy of valganciclovir historical controls. The study hypotheses are: Letermovir prophylaxis will be associated with similar rates of CMV infection as valganciclovir among heart and lung transplant recipients Letermovir will be better tolerated than valganciclovir for CMV prophylaxis in heart and lung transplant recipients, with a higher proportion of days of completed therapy with correct dosing during the planned prophylaxis period Letermovir will have a lower rate of neutropenia than valganciclovir when used for CMV prophylaxis in heart and lung transplant recipients Incorrect renal dosing will occur less frequently with letermovir than with valganciclovir when used for CMV prophylaxis in heart and lung transplant recipients

Anti-viral T-cell Therapy by Gamma Capture

AdenovirusCytomegalovirus Infections1 more

The primary purpose of this phase I/II study is to evaluate whether partially matched, ≥1/6 Human Leukocyte Antigens (HLA) -matched, viral specific T cells have efficacy against adenovirus, Cytomegalovirus (CMV), and Epstein Barr Virus (EBV) in subjects who have previously received any type of allogeneic Hematopoietic Cell transplant (HCT) or solid organ transplant (SOT) or have compromised immunity. Reconstitution of anti-viral immunity by donor-derived cytotoxic T lymphocytes has shown promise in preventing and treating infections with adenovirus, CMV, and EBV. However, the weeks taken to prepare patient-specific products, and cost associated with products that may not be used limits their value. This trial will evaluate viral specific T cells generated by gamma capture technology. Eligible patients will include HCT and/or SOT recipients, and/or patients with compromised immunity who have adenovirus, CMV, or EBV infection or refractory viremia that is persistent despite standard therapy. Infusion of the cellular product will be assessed for safety and efficacy.

Multi-antigen CMV-MVA Triplex Vaccine in Reducing CMV Complications in Patients Previously Infected...

Accelerated Phase Chronic Myelogenous LeukemiaBCR-ABL1 Positive13 more

This randomized phase II trial studies the safety and how well multi-peptide cytomegalovirus (CMV)-modified vaccinia Ankara (MVA) vaccine works in reducing CMV complications in patients previously infected with CMV and are undergoing a donor hematopoietic cell transplant. CMV is a virus that may reproduce and cause disease and even death in patients with lowered immune systems, such as those undergoing a hematopoietic cell transplant. By placing 3 small pieces of CMV deoxyribonucleic acid (DNA) (the chemical form of genes) into a very safe, weakened virus called MVA, the multi-peptide CMV-MVA vaccine may be able to induce immunity (the ability to recognize and respond to an infection) to CMV. This may help to reduce both CMV complications and reduce the need for antiviral drugs in patients undergoing a donor hematopoietic cell transplant.

Accelerated Phase Chronic Myelogenous LeukemiaBCR-ABL1 Positive14 more

This randomized phase II trial studies how well vaccine therapy works in reducing the frequency of cytomegalovirus severe infections (events) in patients with hematologic malignancies undergoing donor stem cell transplant. Vaccines made from a peptide may help the body build an effective immune response and may reduce cytomegalovirus events after donor stem cell transplant.

Accelerated Phase Chronic Myelogenous LeukemiaAdult Acute Lymphoblastic Leukemia in Remission125 more

This randomized phase I trial studies the side effects of vaccine therapy in preventing cytomegalovirus (CMV) infection in patients with hematological malignancies undergoing donor stem cell transplant. Vaccines made from a tetanus-CMV peptide or antigen may help the body build an effective immune response and prevent or delay the recurrence of CMV infection in patients undergoing donor stem cell transplant for hematological malignancies.

Study of Adoptive Immunotherapy With Donor-derived CMV-specific T Cells for Recipients of Allo-HSCT...

Haematological MalignanciesCMV Infection

The study will test the hypothesis that CMV TCR-transduced T cells, at a specific T-cell dose/kg, can generate a functional CMV immune response post-transplant, where CMV-specific donor T cells cannot be isolated by conventional means. This will be tested in the context of adult HLA-matched sibling allogeneic HSCT. In the proposed trial, an HLA-A*0201-restricted CMV pp65-specific T cell receptor (TCR) will be introduced into donor T cells via ex vivo GMP retroviral transduction. Donor T cells will be isolated from peripheral blood following a simple venesection procedure. The CMV TCR-transduced T cells will be tested for TCR expression, CMV-specific cytokine secretion and microbiological contamination before being frozen and stored at -80C. CMV seropositive transplant recipients will be tested weekly for CMV reactivation by quantitative PCR on peripheral blood. On first detection of CMV DNA > 200 copies/ml, 104 (cohort 1) or 105 (cohort 2) bulk CMV TCR-transduced T cells/kg recipient weight will be infused into the patient. Blood will be taken regularly to determine persistence and expansion of the CMV TCR-transduced T cells. Weekly CMV PCR will be continued. Patients will be examined at appropriate intervals (daily if inpatients, twice weekly in BMT clinic if outpatients) for the development of graft versus host disease (GVHD) or other potential side effects.

Effectiveness of an Immune-guided Cytomegalovirus Infection Preventive Strategy Compared to a Universal...

Kidney Transplant Infection

Cytomegalovirus (CMV) establishes a chronic infection in 60% of the general population. In renal transplant recipients, it is responsible for morbidities occurring mainly in the first 6 months after transplantation. These include viral reactivations linked to immunosuppressive treatment inhibiting the anti-CMV T lymphocyte response. CMV infection, a sign of uncontrolled viral replication, is defined by the detection of viral DNA in the peripheral blood (DNAemia). CMV disease is defined as the association of an infection and symptoms attributable to the virus. In transplant recipients carrying the virus before transplantation (positive serology: CMV+), two infection prevention strategies are recommended: either close monitoring of DNAemia with antiviral treatment in the event of positive detection (pre-emptive strategy), or antiviral treatment for the first 3 months following the transplant (prophylactic strategy). Both strategies result in the occurrence of CMV infection in 15 to 20% of patients within the first 6 months, with the majority of events occurring between 3 and 6 months. Numerous studies show that the evaluation of the anti-CMV T lymphocyte response, either before (D0) or early after transplantation (D15), or when antiviral prophylaxis is stopped, allows the identification of patients at risk of CMV infection. No study has yet demonstrated the contribution of such an evaluation in a preventive strategy. We therefore propose such a study.

Prenatal Treatment of Congenital Cytomegalovirus Infection With Letermovir Versus Valaciclovir

Pregnant WomenCMV Infected Fetuses

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 cord blood. 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.
