Treatment of Refractory BK Infections With Related Donor BK Specific Cytotoxic T-cells (CTLs)

October 24, 2023 updated by: New York Medical College

A Pilot Study in the Treatment of Refractory BK Infections With Related Donor BK Specific Cytotoxic T-cells (CTLs) in Children, Adolescents and Young Adult Recipients

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).

Description

Inclusion Criteria:

.1.1 Patients with refractory BK infection post allogeneic HSCT, post solid organ transplantation or with primary immunodeficiencies with either

  • Medical intolerance to anti-viral therapies including:

    • 2 renal toxicity with cidofovir or other > grade 2 toxicities secondary to cidofovir And/or
  • known resistance to cidofovir 1.2. Consent: Written informed consent given (by patient or legal representative) prior to any study-related procedures.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: BK CTL
Eligible patients with refractory BK infection will receive up to 5 infusions of BK CTLs that are donor derived.

Patient with refractory BK infection and a HLA Matched Related Donors: BK specific CTLs (2.5 x 104 CD3/kg) infused intravenously on day 0 and may be additionally reinfused at a minimum of every two weeks (depending on safety and efficacy) for a maximum of five total infusions (maximum 12.5 x 104 CD3/kg).

Patients with refractory BK virus and a HLA Mismatched Related Donors: BK specific CTLs (0.5x104 CD3/kg) infused intravenously on day 0 and may additionally be reinfused at a minimum of every two weeks (depending on safety and efficacy) for a maximum of five total infusions (maximum 2.5 x 104 CD3/kg).
