Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults aged 18 to 60 with certain blood cancers who will have a stem cell transplant from a related or unrelated donor with a compatible tissue type.

Age
18 to 60 years
Sex
All sexes can join.
Disease stage
Acute leukemia in first or second remission; myelodysplasia with less than 20% blasts; Hodgkin or non-Hodgkin lymphoma in partial remission after salvage therapy.
Earlier treatment
People must be ready for a transplant with a related or unrelated donor with a compatible tissue type (HLA-compatible), using stem cells from peripheral blood. The conditioning before the transplant must be FluMel, FluTBI, CyTBI, BuCy or BuFlu.

Main reasons for not taking part

  • Liver problems (transaminases 2 times the normal value)

About the trial

What the trial wants to find out

Hematopoietic stem cell transplantation is a curative treatment for a number of benign and malignant hematologic diseases. One of the key parts of hematopoietic stem cell transplantation is the prophylaxis of graft-versus-host disease. Since the end of the 1970s, with the introduction of cyclosporine, calcineurin inhibitors (cyclosporine and tacrolimus) have become part of almost all prophylactic regimens, even though they are a group of drugs with a poor toxicity profile that requires monitoring. constant serum level. Since 2008, post-transplant cyclophosphamide has been introduced with great success, associated with a calcineurin inhibitor and mycophenolate, in the prophylaxis of graft-versus-host disease in haploidentical transplantation (50% matched).

Since then, in view of this enormous success, efforts have been made to incorporate post-transplant cyclophosphamide in matched related and unrelated transplants, or with a mismatch.

This is a prospective, 2-arm, non-randomized study. Arm 1, with related donors, and arm 2, with unrelated donors. Patients will be allocated in these arms according to donor availability (patients with a matched-sibling donor will receive a matched-sibling transplant; patients with no related donors but with unrelated donors, an unrelated transplant).

Patients who are ready for transplantation with matched-sibling or unrelated donors will be recruited to participate in the study.

The stem cell collection target will be 5E6 CD34/kg recipient weight for peripheral source. If a quantity greater than this is collected, the remainder will be cryopreserved according to the institutional protocol.

Graft-versus-host disease prophylaxis will be performed on D+3 and D+4 with cyclophosphamide and with ATG on D-3 and D-2 for matched-sibling or unrelated donors transplants.

The 2 groups in the trial

  • Matched-sibling donor transplantsTreatment being tested

    Matched sibling transplants will receive PTCy + ATG4.0

    Treatment: Cyclophosphamide injection and ATG 4.0

  • Matched unrelated donor transplantsTreatment being tested

    Unrelated transplants will receive PTCy + ATG5.0

    Treatment: ATG 5.0 and Cyclophosphamide injection

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
