Advanced Physician Search: Transplant

This randomized, open-label, parallel group, two-arm, multi-center assessment will compare IV BCV with IV CDV in adult and pediatric allogeneic HCT recipients with AdV viremia. A virologic response-driven approach to duration of treatment will be evaluated, in which randomized subjects are treated with either BCV or CDV until AdV viremia is confirmed as undetectable or until a maximum of 12 weeks of therapy, whichever occurs first. All subjects will be followed for a total of 24 weeks post-randomization, regardless of treatment assignment. Subjects will be assessed on a weekly basis through the end of treatment visit (EOT). Additional assessments will be performed at the test of cure (TOC) visit, which is 4 weeks after the last dose of study drug and at Weeks 12 and 24 post W1D1.

BK cytotoxic T cells (CTLs) manufactured with the Miltenyi CliniMACS Prodigy Cytokine Capture System will be safe and effective in decreasing specific viral load in children, adolescents and young adults (CAYA) with refractory BK infection post Allogeneic Hematopoietic Stem Cell Transplantation (AlloHSCT) or with primary immunodeficiencies (PID).

Biological: BK CTL

This single arm pilot phase I study with safety run-in is designed to estimate the safety and efficacy of a familial mismatched or haploidentical hematopoietic stem cell transplantation (haplo-HSCT) using a novel graft modification technique (selective αβ-TCR and CD19 depletion).
