Trial summary
RATIONALE: Giving low doses of chemotherapy, such as fludarabine and melphalan, before a donor stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. Read more about this study

About this study
Official title: Multicenter Randomized Phase II Study to Evaluate the Efficacy of Prophylactic Transfer of CD4 Lymphocytes After T-cell Depleted Reduced Intensity HLA-Identical Sibling Transplantation for Haematological Cancers
RATIONALE: Giving low doses of chemotherapy, such as fludarabine and melphalan, before a donor stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) that have been treated in the laboratory after the transplant may help increase this effect. Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving alemtuzumab before transplant and cyclosporine after transplant, may stop this from happening.
PURPOSE: This randomized phase II trial is studying donor lymphocyte infusion after stem cell transplant in preventing cancer relapse or cancer progression in patients with follicular lymphoma, small lymphocytic non-Hodgkin lymphoma, or chronic lymphocytic leukemia.
Read the detailed description
OBJECTIVES:
Primary
- To evaluate the effect of prophylactic transfer of donor CD4 cells after T-cell depleted reduced-intensity HLA-identical sibling transplantation upon the risk of relapse or progression in patients with haematological cancers (e.g. NHL, HL, CLL/PLL, PCM, AML, ALL, MDS or CMML depending on the disease status).
Secondary
- To evaluate the effect of prophylactic transfer of donor CD4 cells upon the risk of graft-versus-host disease (GvHD) in these patients.
- To evaluate the effect of prophylactic transfer of donor CD4 cells upon the rates of conversion to full donor chimerism in peripheral blood in these patients.
- To determine the effect of prophylactic transfer of donor CD4 cells upon immune reconstitution in these patients.
- To evaluate the impact of prophylactic transfer of donor CD4 cells upon non-relapse mortality and overall survival of these patients.
OUTLINE: This is a multicenter study.
Patients receive fludarabine IV, melphalan IV, and alemtuzumab IV as reduced intensity conditioning for T-cell depletion followed by a reduced-intensity HLA-identical sibling stem cell transplantation on day 0. Withdrawal of cyclosporine immunosuppression therapy commence at day 40 with tapering over a period of 3-4 weeks, according to the discretion of the PI. Patients are reassessed between day 70-90 post-transplantation. Patients with stable engraftment, no significant graft-versus-host disease, and no early relapse or progression are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive an allogeneic CD4 donor lymphocyte infusion (DLI) at a dose of 1 x10^6 CD4 cells/kg body weight without any other medication once between day 100-120.
- Arm II: Patients receive no further treatment.
Patients undergo blood sample collection for chimerism studies and translational research.
After completion of study treatment, patients are followed up periodically for 1 years and then annually.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing CD4 DLI and No DLI in people with Graft Versus Host Disease and Leukemia, run by University College, London at 11 sites in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 0 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 12 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression-free survival at 1 year post-transplant (time frame: during the study and end of study). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Feb 2019; AzTrials last refreshed its copy on 7 Nov 2026.
