Brief Summary:

CMV cytotoxic T cells (CTLs) manufactured with the Miltenyi CliniMACS Prodigy Cytokine Capture System will be administered in children, adolescents and young adults (CAYA) with refractory cytomegalovirus (CMV) infection post Allogeneic Hematopoietic Stem Cell Transplantation (AlloHSCT), with primary immunodeficiencies (PID) or post solid organ transplant.

Funding Source: FDA OOPD

Condition or disease Intervention/treatment Phase
Cytomegalovirus Infections Primary Immune Deficiency Disorder Drug: viral specific cytotoxic t-lymphocytes Phase 2

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 20 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Intervention Model Description: All eligible patients will be given CMV specific CTLs and dose is based on donor source: HLA matched and HLA mismatced
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Pilot Study in the Treatment of Refractory Cytomegalovirus (CMV) Infections With Related Donor CMV Specific Cytotoxic T-cells (CTLs) in Children, Adolescents and Young Adult Recipients
Actual Study Start Date : November 1, 2018
Estimated Primary Completion Date : August 31, 2023
Estimated Study Completion Date : December 31, 2023

Arm Intervention/treatment
Experimental: Refractory CMV
Patients with refractory CMV will be given one dose of CMV specific CTLs. HLA matched donors will get Dose 2.5 × 10(4) CD3/kg recipient weight; HLA mismatched will get 0.5x10(4) CD3/kg recipient weight. Additional doses may be given for a total of 5 doses if patients do not have a response to the first dose with a reduction in viral load to normal limits.
Drug: viral specific cytotoxic t-lymphocytes
CMV specific CTLs will be collected from HLA matched or mismatched donors and manufactured in a GMP facility and administered to patients with refractory CMV infection.
Other Name: CMV CTLs

Primary Outcome Measures :
  1. Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] [ Time Frame: Patients will be followed for 12 weeks after each infusion ]
    Patients will be monitored for adverse events following the administration of CMV CTLs

  2. Incidence of Response to Treatment [ Time Frame: Patients will be followed 12 weeks after each infusion ]
    Patients will be followed for improvement in viral infection by monitoring CMV PCR weekly for response to treatment with CTLs

Performance Status > 30% (Lansky < 16 yrs and Karnofsky > 16 yrs) Age: 0.1 to 30.99 years Females of childbearing potential with a negative urine pregnancy test

Donor Eligibility Related donor available with a T-cell response to the CMV MACS® GMP PepTivator antigen(s).

a. Third Party Allogeneic Donor: If original donor is not available or does not have a T-cell response: third party related allogeneic donor (family donor > 1 HLA A, B, DR match to recipient) with IgG positive to CMV and/or a T-cell response to the CMV MACS® GMP PepTivator .

AND Allogeneic donor disease screening is complete similar to hematopoietic stem cell donors (Appendix 1).

AND Obtained informed consents by donor or donor legally authorized representative prior to donor collection.

3 Patient exclusion criteria:

A patient meeting any of the following criteria is not eligible for the present study:

Patient with acute GVHD > grade 2 or extensive chronic GVHD at the time of CMV CTL infusion Patient receiving steroids (>0.5 mg/kg prednisone equivalent) at the time of CMV CTL infusion Patient treated with donor lymphocyte infusion (DLI) within 4 weeks prior to CMV CTL infusion Thymoglobulin (ATG), Alemtuzumab or T cell immunosuppressive monoclonal antibodies within 30 days Patient with poor performance status determined by Karnofsky (patients >16 years) or Lansky (patients ≤16 years) score ≤30% CMV retinitis Concomitant enrollment in another experimental clinical trial investigating the treatment of refractory CMV infection.

Any medical condition which could compromise participation in the study according to the investigator's assessment Known HIV infection Female patient of childbearing age who is pregnant or breast-feeding or not willing to use an effective method of birth control during study treatment.

Known hypersensitivity to iron dextran Patients unwilling or unable to comply with the protocol or unable to give informed consent.

Known human anti-mouse antibodies
