Study summary

This study aimed to evaluate the efficacy of reduced intensity conditioning (RIC) regimen in elderly or high comorbidity burden patients who receive haploidentical hematopoietic stem cell transplantation (haplo-HSCT). Haplo-HSCT is an effective treatment option for patients who did not have identical sibling donor (ISD) or unrelated donor (URD). However, post-transplant transplant-related mortality (TRM) is one of the major causes for transplant failure, and the risk of TRM for old patients or those with high comorbidity burden was higher. RIC regimen may decrease the risk of TRM for haplo-HSCT recipients. The study hypothesis: Using RIC haplo-HSCT regimen in elderly patients or those with high comorbidity burden can reduce TRM and improve survival.

Read the detailed description

RIC regimen was given for elderly patients or those with high comorbidity burden who would receive haplo-HSCT. The elderly patients were defined as older than 55 years. The burden of comorbidities in HSCT recipients was assessed based on the hematopoietic cell transplantation-specific comorbidity index (HCT-CI), and patients with score ≥3 were assigned as high burden. The primary end point was transplant-related mortality, and the secondary endpoints included overall survival, disease-free survival, relapse, engraftment, graft-versus-host disease (GVHD), and infections. Following time is 1 years.

  • Experimental
    RIC regimen

    Old patients or those have high comorbidity burden without identical sibling donor or unrelated donor would receive RIC haplo-HSCT. RIC preconditioning regimen consisted of cytarabine (2 g/m2/day, days -10 to -9), busulfan (3.2 mg/kg/day on days -8 to -6), cyclophosphamide (1.0 g/m2/day, days -5 to -4), fludarabine (30 mg/m-2/day, days -6 to -2), semustine (250 mg/m-2, day -3), and rabbit antithymocyte globulin (thymoglobulin, 2.5 mg/kg/d, days -5 to -2; Sanofi, France).

    Drug: Cytarabine

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Feb 2018 (actual). Primary completion is estimated for Sep 2025, 91 months after the start.

Of 227 non-industry phase 2 interventional studies under Myelodysplastic Syndromes, half reached primary completion within 76 months of starting (the median), counting those still running; a quarter within 44 and three quarters within 116. This study's planned 91 months is above that.

Counting every sponsor, half of 279 studies reached it within 66 months; a quarter within 40 and three quarters within 104.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 26, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
