NCT02942173

Brief Summary

The purpose of this prospective randomized study is to determine whether infusions of T-memory cells prevent infections in children with leukemia after allogeneic alpha, beta T-cell receptor (TcRab)/CD19-depleted hematopoietic stem cell transplantation (HSCT).

Eligibility Criteria

AgeUp to 25 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Patients who are considered candidates for allogeneic hematopoietic stem cell transplantation and have one of the following diagnoses:
  • Acute lymphocytic leukemia (ALL)
  • Acute myeloid leukemia
  • Acute biphenotypic leukemia
  • Acute bilinear leukemia
  • Lymphoma
  • Myelodysplastic syndrome
  • Chronic myeloid leukemia
  • Transplant processing: TCR ab/CD19-depletion
  • Donors:
  • HLA-match unrelated volunteers
  • Partly and haploidentical relative

You may not qualify if:

  • ALL patients not in remission
  • Patients with uncontrolled infections
  • Clearance of creatinine \< 70 ml/min
  • Cardiac ejection fraction \< 40%
  • Patients who can perform pulmonary function tests will be excluded if they have a diffusing capacity of the lung for carbon monoxide (DLCO) (corrected for hemoglobin) of \< 50% predicted; patients who are unable to perform pulmonary function tests will be excluded if the oxygen (O2) saturation is \< 92% on room air
  • Patients who have liver function test (LFTs) (including total bilirubin, aspartate aminotransferase \[AST\] and alanine aminotransferase \[ALT\]) \>= twice the upper limit of normal
  • Mental disease of both patient, patient's tutor (if patient is under age 18) and donor, that hinder understanding of main point of the study and keeping treatment plan, hygiene and sanitation
