NCT ID: NCT06219616 Recruiting - Clinical trials for Kidney Transplant Infection

Prediction of BK Virus Reactivation in Kidney Transplant Recipient

Start date: May 1, 2023
Phase: N/A
Study type: Interventional

There has been no effective predicting tool to accurately predict BKV reactivation after kidney transplantation. The aim is to elucidate the use of flow cytometric analysis for both intracellular cytokines and surface activation markers for BKV-specific T cell response in kidney transplant recipients.

NCT ID: NCT05618275 Recruiting - BK Virus Infection Clinical Trials

Role of Neutralizing Antibodies in the Prediction and Treatment of BK Virus Infection in Hematopoietic Stem Cell Allograft Patients at the Pediatric Oncology-hematology Department of the HUS

BKV-Allograf
Start date: January 1, 2020
Phase:
Study type: Observational

The BK virus (BKV) belongs to the Polyomaviridae family. The primary infection, generally asymptomatic, occurs during childhood. The virus then persists in latent form in the body, mainly in the epithelial cells of the kidney and urinary tract. Cellular immunosuppression favors BKV replication. It is responsible for pathologies of the renal-urinary tract such as BKV-associated nephropathy (BKVAN) in kidney transplant recipients, hemorrhagic cystitis (HC) in hematopoietic stem cell (HSC) recipients or ureteral stenosis. To date, there is no specific antiviral treatment against BKV. The management of patients is essentially symptomatic and requires a multidisciplinary approach. It is therefore necessary to identify early prognostic markers for the occurrence of CH and to develop new therapeutic strategies.

NCT ID: NCT05511779 Recruiting - Clinical trials for Kidney Transplantation

Study to Confirm of the Safety and Tolerability of Brincidofovir in Subjects With BK Virus Infection (Viremia) After Kidney Transplantation

Start date: October 14, 2022
Phase: Phase 2
Study type: Interventional

This is a Phase II, multicenter, open-label, randomized, standard of care (SOC) controlled, multiple ascending dose study to assess the safety and tolerability of IV Brincidofovir (BCV) in subjects with BKV infection after kidney transplantation. The study will be conducted at multiple study sites in several countries including Australia and Japan. Subjects who meet eligibility criteria will be enrolled in the study and will be randomized and assigned to BCV or SOC (defined as use of the same immunosuppressant administered during prescreening) before receipt of the first dose of study drug in both the Dose Escalation Phase and the Expansion Phase.

NCT ID: NCT05305040 Terminated - Clinical trials for Cytomegalovirus Infections

Study of Posoleucel (ALVR105,Viralym-M) for Multi-Virus Prevention in Patients Post-Allogeneic Hematopoietic Cell Transplant

Prevent
Start date: March 21, 2022
Phase: Phase 2/Phase 3
Study type: Interventional

This is a Phase 3 study to evaluate posoleucel (ALVR105, Viralym-M); an allogeneic, off-the-shelf multi-virus specific T cell therapy that targets six viral pathogens: BK virus, cytomegalovirus, adenovirus, Epstein-Barr virus, human herpesvirus 6 and JC virus.

NCT ID: NCT05264259 Not yet recruiting - BK Virus Infection Clinical Trials

New Therapeutic Approach Against BK Virus Infection Based on Monoclonal Antibodies

AcMBK
Start date: March 5, 2022
Phase:
Study type: Observational

BK virus (BKV) infection has a major negative impact on transplant recipients. No BKV-specific antiviral therapy is available, so there is an urgent need to develop new anti-BKV preventive and therapeutic strategies.

NCT ID: NCT05183490 Recruiting - Clinical trials for Cytomegalovirus Infections

R-MVST Cells for Treatment of Viral Infections

Start date: May 3, 2022
Phase: Phase 1
Study type: Interventional

The primary objective is to determine the safety and feasibility of administering R-MVST cells to patients with refractory viral reactivation and/or symptomatic disease caused by Epstein Barr Virus (EBV), cytomegalovirus (CMV), adenovirus (ADV) or BK virus. R-MVST cells will be generated on-demand from the closest partially human leukocyte antigen (HLA)-matched (minimum haploidentical) healthy donors or from the original allo-transplant donor if available. The investigator will closely monitor the recipients for potential toxicities including graft-versus-host disease (GVHD) post-infusion. Secondary objectives are to determine the effect of R-MVST infusion on viral load, possible recovery of antiviral immunity post-infusion and for evidence of clinical responses and overall survival. Recipients will be monitored for secondary graft failure at day 28 post R-MVST infusion.

NCT ID: NCT05101213 Recruiting - Clinical trials for Malignant Solid Neoplasm

Study Assessing the Feasibility, Safety and Efficacy of Genetically Engineered Glucocorticoid Receptor Knock Out Virus Specific CTL Lines for Viral Infections in Immunosuppressed Cancer Patients

Start date: January 6, 2023
Phase: Phase 1
Study type: Interventional

This phase I trial tests the feasibility and safety of genetically modified cytotoxic T-lymphocytes in controlling infections caused by adenovirus (ADV), BK virus (BKV), cytomegalovirus (CMV), JC virus (JCV), or COVID-19 in immunocompromised patients with cancer. Viral infections are a leading cause of morbidity and mortality after hematopoietic stem cell transplantation, and therapeutic options for these infections are often complicated by associated toxicities. Genetically modified cytotoxic T-lymphocytes (CTLs) are designed to kill a specific virus that can cause infections. Depending on which virus a patient is infected with (ADV, BKV, CMV, JCV, or COVID-19), the CTLs will be designed to specifically attack that virus. Giving genetically modified CTLs may help to control the infection.

NCT ID: NCT05042076 Recruiting - Clinical trials for Kidney Transplant Infection

BK With VST for Kidney Transplant Patients

Start date: December 16, 2021
Phase: Phase 1
Study type: Interventional

This study measures the safety, feasibility, and efficacy of viral-specific T cells (VST) against BK Virus (BKV) in adult kidney transplant recipients. Participants are expected to be on study for 52 weeks.

NCT ID: NCT05026021 Recruiting - Clinical trials for Kidney Transplantation

Prediction of BKvirus Nephropathy Risk by the NEPHROVIR Method in Kidney Transplant Patients With BKvirus Viremia

BK-VIR
Start date: September 2, 2021
Phase:
Study type: Observational

BKvirus associated nephropathy (BKvAN) is a major complication in kidney transplantation. Due to BKvirus (BKv) intra-graft replication, BKvAN affects nearly 10% of patients and causes graft loss in more than 50% of cases. Without current antiviral therapy, the treatment consists of minimizing immunosuppression, secondarily exposing the patient to a graft rejection risk. Impaired BKv specific T cell response plays a crucial role in the BKvAN pathophysiology. Several teams, including ours, have demonstrated a profound impairment of BKv specific T cell response during BKvAN. Immunovirological monitoring allows an individual assessment of viral reactivation risk based on the anti-viral immune response. Our group has developed the NEPHROVIR method. This non-invasive biological method for BKvAN allows the identification of BKvAN risk level. The aim of this work is to evaluate, by the NEPHROVIR method, the risk to develop a BKvAN with renal impairment in kidney transplant recipients with sustained BKv viremia. The investigators propose the BKVIR study. This is a prospective multicentric study involving 100 kidney transplant recipients with sustained BKv viremia. The aim of this work is to evaluate the NEPHROVIR method as an innovative immunovirological surveillance method for predicting the risk of BKvAN occurrence. The characterization of individual BKvAN risk level could help in the individualized follow-up and management of immunosuppression in patients. The long-term objective would be to diagnose very early, or even anticipate, the occurrence of BKvAN and to allow early readjustment of the immunosuppressive treatment.
