Brief summary
The primary objective of this proposal is to conduct the first-in-human randomized clinical trial evaluating prophylactic DLI-X (pro-DLI-X) for relapse prevention following matched sibling donor (MSD) or haploidentical (haplo) hematopoietic cell transplantation (HCT) in patients with hematologic malignancies. Additionally, the study aims to assess the safety and efficacy of therapeutic DLI-X (t-DLI-X) compared to t-DLI alone in patients with minimal residual disease (MRD+) or overt relapse post-alloHCT. For patients with CD19-positive lymphoid malignancies, the study will incorporate blinatumomab, while those with myeloid or CD19-negative lymphoid malignancies will receive t-DLI-X or t-DLI alone. We hypothesize that both pro-DLI-X and t-DLI-X, with or without blinatumomab, will demonstrate safety and superior efficacy by enhancing graft-versus-leukemia (GvL) effects mediated by natural killer (NK) cells, γδ T cells, and CD8+ T cells, while maintaining manageable and treatment-responsive graft-versus-host disease (GvHD).
Interventions
Pro-DLI-X will be given through the patient's central line at an initial dose of 100,000 CD3+ cells/kilogram (kg) of recipient weight for haploidentical hematopoietic cell transplantation (haploHCT) and 300,000 CD3+ cells/kg for matched sibling donor hematopoietic cell transplantation (MSD HCT). Participants will receive up to 3 doses of pro-DLI-X, and each dose will be increased as follows: dose 2 will be 300,000 CD3+ cells/kg for haploHCT and 1,000,000 CD3+ cells/kg for MSD HCT; dose 3 will be 1,000,000 CD3+ cells/kg for haploHCT and 3,000,000 CD3+ cells/kg for MSD HCT.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Prophylactic endpoint: Graft-versus-Host Disease-Free, Relapse-Free Survival (GRFS) | Assess between 1 to 3 years post HCT | Graft-versus-Host Disease-Free, Relapse-Free Survival (GRFS) is defined as survival without evidence of disease relapse or grade III-IV acute graft-versus-host-disease (aGvHD) or chronic graft-versus-host-disease (cGvHD) requiring systemic therapy. In essence, GRFS serves as a meaningful measure encompassing not only survival but quality of life. GRFS will be compared in patients randomized to pro-DLI-X versus standard pro-DLI control group. |
| Therapeutic endpoint: Disease response to t-DLI versus t-DLI-X (relapse and GvHD rates as a composite endpoint) | Assess between 1-3 years post HCT | A parallel two-group design will be used to test whether the percent response to t-DLI-X (treatment) is different from the percent response to t-DLI (control). |
