25BT056: Basket Study of Viral Cytotoxic T Lymphocytes

This study is evaluating the safety and effectiveness of virus-specific cytotoxic T lymphocytes (vCTLs) for treating difficult-to-control viral infections caused by cytomegalovirus (CMV), adenovirus (ADV), Epstein-Barr virus (EBV), or BK virus in children, adolescents, and young adults with weakened immune systems. Eligible participants include recipients of hematopoietic stem cell transplantation, solid organ transplantation, and patients with primary immunodeficiency disorders. vCTLs are immune cells collected from a related donor and selected to recognize and fight specific viruses. The cells are manufactured using the CliniMACS® Cytokine Capture System and administered by intravenous infusion. Additional infusions may be given if viral infection persists. The study will assess the safety of vCTL therapy, including the risk of graft-versus-host disease (GVHD) and infusion-related reactions, as well as its ability to reduce viral infection, improve clinical outcomes, and support survival. Participants will be monitored for approximately 12 weeks after their final vCTL infusion. Participants will all receive vCTLs; there is no comparison group. Participants will: 1. Have donor-derived vCTLs manufactured for infusion using the CliniMACS Cytokine Capture System 2. Receive the vCTLs through an intravenous infusion 3. Be monitored for side effects and infusion reactions, viral levels through blood testing, clinical outcomes, including response to treatment, survival, and time without detectable virus

A Trial to Treat Polyomavirus Infections (BKPyV) in Kidney and Simultaneous Kidney Pancreas Transplant Recipients

BEAT-BK will see the effect of immunosuppression reduction/modification with and without IVIG on BKPyV infection, allograft function, allograft loss, acute transplant rejection, immunosuppression load and death in kidney and simultaneous kidney pancreas transplant recipients with polyomavirus infections (BKPyV).

Prevalence of BK Viremia in Simultaneous Liver-Kidney Transplant

The human BK polyomavirus is a significant risk factor for renal transplant dysfunction and allograft loss. The prevalence of BK viremia (BKV) following kidney transplantation is estimated to be 10-20%.
