The goal of this clinical trial is to learn if haploidentical hematopoietic cell transplantation combined with an unrelated cord blood unit (haplo-cord HCT) works to treat acute T cell lymphoblastic leukemia (T-ALL). It will also learn about the safety of the transplantation. The main questions it aims to answer are:
Dose co-infusion of cord blood in haploidentical hematopoietic cell transplantation (haplo-HCT) lower the rate of relapse? What medical problems do participants have when having haplo-cord HCT? Researchers will compare haplo-cord HCT to haplo-HCT to see if haplo-cord HCT works to treat T-ALL.
Participants will be infused an unrelated cord blood unit at the same day of haploidentical graft infusion.
Patients with acute T cell lymphoblastic leukemia
With available minimal residual disease parameters assessed by flow cytometry and/or quantitative polymerase chain reaction
Willing to undergo haploidentical hematopoietic cell transplantation and having a suitable haploidentical donor
With Eastern Cooperative Oncology Group (ECOG) performance status of 0-3
With other malignancies
Failing to acquire a suitable unrelated cord blood unit
With a previous history of autologous hematopoietic cell transplantation, allogeneic hematopoietic cell transplantation or chimeric antigen receptor T cell therapy
With uncontrolled infection intolerant to haploidentical hematopoietic cell transplantation
