NCT04232241

Brief Summary

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%.

Outcome Measures

Primary Outcomes (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.

    2 years

Secondary Outcomes (11)

  • Overall survival at two years between both arms

    2 years

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

    through study completion, an average of two yeras

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

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

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

    At 1 and 2 years after allogeneic SCT

  • 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

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

  • +6 more secondary outcomes
