About this study

Official title: Matched Unrelated vs. Haploidentical Donor for Allogeneic Stem Cell Transplantation in Patients With Acute Leukemia With Identical GVHD Prophylaxis - A Randomized Prospective European Trial.

Primary objective of this open label, two-arm, multicenter, multinational, randomized trial is to compare anti-leukemic activity of allogeneic stem cell transplantation for patients with acute leukemia in complete remission between a 10/10 HLA matched unrelated donor and a haploidentical donor.

The hypothesis: Haploidentical stem cell transplantation with post cyclophosphamide induces a stronger anti-leukemic activity in comparison to 10/10 HLA matched unrelated donor and reduces the risk of relapse at 2 years after stem cell transplantation by 10%.

Read the detailed description

Secondary objectives are to assess and compare the safety and efficacy of study treatments therapy in both study arms on non-relapse mortality (NRM), relapse-free survival (RFS), Overall survival (OS), QOL, toxicity, development of acute and chronic GvDH as well as engraftment and chimerism and impact of measurable residual disease.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Relapse incidence at two years between both arms

    The primary efficacy endpoint will be analyzed using cumulative incidence estimation to assess the subdistribution hazard rates for both treatment groups at two years after accounting for competing risk events.

    Measured: 2 years

Secondary outcomes (11)
  1. Overall survival at two years between both arms

    The overall survival at two years between both arms will be presented with Kaplan-Meier's estimates of survival.

    Measured: 2 years

  2. Overall survival for all patients assigned to one of the two treatment arms as time to event endpoint

    The overall survival for all patients will be presented with Kaplan-Meier curve. To compare the survival distributions between two arms, log-rank test will be performed, and two-sided p-values will be presented.

    If applicable, Cox regression model stratified by the types of leukemia, types of complete remission and conditioning will be performed as sensitivity analysis.

    Measured: through study completion, an average of two yeras

  3. Comparison of GVHD/relapse-free survival as Composite endpoint in both arms

    The rate of composite endpoint in both arms will be analyzed with the same methods as for the overall survival at two years between both arms.

    Measured: Starting at day +30 (+/- 3 d) to 24 months (+/- 1 mo) after allogenic stem cell transplantation (SCT)

  4. Comparison of non-relapsed mortality (NRM) at 1 and 2 years after allogeneic SCT in both arms

    Due to the existence of competing risk events (persisting disease and relapse), NRM of each arm at 1 and 2 years after allogeneic SCT will be analyzed with the same methods as for the primary endpoint

    Measured: At 1 and 2 years after allogeneic SCT

  5. Comparison of acute graft-versus-host disease (aGVHD) on day +100 and 1 year (max grade) after allogeneic SCT according to the Glucksberg scale revised by Przepiorka et al. between both arms

    For each time point, the frequency and percentage of aGVHD (maximum grade) of each arm will be presented. To compare the difference between both arms, logistic regression adjusted for covariates and stratification factors will be performed.

    Measured: On day +100 and 1 year (max grade) after allogeneic SCT

  6. Comparison of chronic graft-versus-host disease (cGVHD) according to the NIH consensus criteria of Jagasia et al. at 1 and 2 years after allogeneic SCT between both arms

    For each time point, the frequency and percentage of cGVHD of each arm will be presented. To compare the difference between both arms, logistic regression adjusted for the stratification factors will be performed.

    Measured: At 1 and 2 years after allogeneic SCT

  7. Comparison of toxicity of both regimens scored according to the current version of the NCI CTCAE between both arms

    Safety will be analyzed with frequency of patients with AEs as described above.

    Measured: through study completion, an average of two yeras

  8. Comparison of immune reconstitution between both arms

    Frequency and percentage of patients having immune reconstitution in two arms will be provided. For the comparison between two arms, logistic regression adjusted for the stratification factors will be performed.

    Measured: At day 30, 100, 6 months, 1 year and 2 years after allogenic SCT

  9. Comparison of full donor chimerism between both arms

    Frequency and percentage of patients having full donor chimerism in two arms will be provided. For the comparison between two arms, logistic regression adjusted for the stratification factors will be performed.

    Measured: At day 30, 100, 6 months, 1 year and 2 years after allogenic SCT

  10. Evaluation of Sorror Risk Score on outcome after allogeneic SCT

    Comorbidity score after Sorror will be assessed prior to randomization and outcome in both arms will be analyzed according the pre-transplant Sorror score.

    Measured: At baseline

  11. Comparison of QOL (FACT-BMT) before and after transplantation at + 100 days, 6 months, 1 year, 2 years between both arms

    The means of change in scores at each time point (day 100, 6 months, 1 year and 2 years after transplantation respectively) from baseline and the confidence intervals of each arm will be presented. To compare the difference in QOL scores between both arms, logistic regression adjusted for covariates and stratification factors will be performed for each time point.

    Measured: At day 100, 6 months, 1 year and 2 years after allogenic SCT

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Allogeneic Stem Cell Transplantation in people with Acute Myeloid Leukemia in Remission and Acute Lymphoblastic Leukemia in Remission, run by Universitätsklinikum Hamburg-Eppendorf at 24 sites in 7 countries.

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 6 inclusion and 13 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: under way, not looking for participants, as of the sponsor's last update on 22 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 sites in Germany, Spain, Austria, Czechia, Finland and 2 more countries. 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?

This study is still under way. Results are not available in the source record yet.

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?

Relapse incidence at two years between both arms (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04232241, which also lists 1 linked publication.

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 22 Apr 2025.
