About this study

Allogeneic stem cell transplantation (Allo-HSCT) is the effective and even the only treatment for hematological malignancies. The "GIAC" protocol established by our center has successfully crossed the HLA barrier in HLA-mismatched/haploidentical HSCT. The protocol entails the following: treating donors with granulocyte colony-stimulating factor (G-CSF) to induce donor immune tolerance, intensified immunologic suppression to both promote engraftment and to prevent GVHD, antithymocyte globulin (ATG) was included for the prophylaxis of GVHD and graft rejection, and combination of G-CSF-primed bone marrow harvest (G-BM) and G-CSF-mobilized peripheral blood stem cell harvest (G-PB) as the source of stem cell grafts. But peripheral blood transplantation is still prevalent. Compared with BM, G-PB is more convenient to collect, and the number of T lymphocytes and CD34+ cells is higher. It is reported that G-PB has a higher implantation rate and even a higher disease-free survival rate in sibiling-identical transplantation compared with BM transplantation, whereas there were also reports with different conclusions. This prospective, one-arm clinical cohort study aims to evaluate the safety and efficacy of haplotype peripheral blood stem cell transplantation (PBSCT) in the treatment of acute leukemia.

What is being measured

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

  1. engraftment rate

    Neutrophil recovery was defined as an absolute neutrophil count(ANC) of 0.5×10^9/L or more for three consecutive days and platelet recovery, as 20×10^9/L or more for seven consecutive days without transfusion.

    Measured: one year after transplantation

Secondary outcomes (5)
  1. cumulative incidence of acute graft-versus-host disease(GVHD)

    cumulative incidence of acute graft-versus-host disease(GVHD)

    Measured: one year after transplantation

  2. cumulative incidence of chronic GVHD at one year

    cumulative incidence of chronic GVHD at one year

    Measured: one year after transplantation

  3. cumulative incidence of relapse at one year

    Cumulative incidence of relapse was defined as the cumulative incidences of presence of morphological evidence of disease in samples from peripheral blood, bone marrow, or extramedullary sites, or by the recurrence and sustained presence of pre-transplantation chromosomal abnormalities.

    Measured: one year after transplantation

  4. cumulative incidence of non-relapse mortality (NRM) at one year

    NRM was defined as the death without disease progression or relapse.

    Measured: one year after transplantation

  5. overall survival at one year

    OS was defined as the time from the date of first dose until death due to any cause.

    Measured: one year after transplantation

The sponsor lists 5 inclusion and 5 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 17 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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.

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yu Wang, MD (13552647384, ywyw3172@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

engraftment rate (time frame: one year after transplantation). 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 NCT03756675, which also lists 3 linked publications.

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 17 Sep 2020.
