About this study

Official title: Dose Study of Antithymocyteglobulin in Haploidentical Hematopoietic Stem Cell Transplantation for Acute Graft-versus-host Disease Prophylaxis

The purpose of this study is to compare the incidences of GVHD and viral infections in haploidentical hematopoietic stem cell transplant recipients receiving different dose of antithymocyte globulin (ATG) for acute graft-versus-host disease(aGVHD) prophylaxis. Our first objective was to investigate the optimal dose of ATG for aGVHD and second object was to evaluate the effect of different dose of ATG on post-transplant viral infection.

Read the detailed description

Allogeneic hematopoietic stem cell transplantation (allo-HSCT)is the only therapeutic option for many hematological malignancies. Unfortunately, about 75% of patients who require allo-HSCT lack human leukocyte antigen (HLA)-matched donors. The alternative is hematopoietic stem cells from an HLA-mismatched family donor. However, this strategy, which is called haploidentical HSCT, may be associated with high risk of early death and severe GVHD.

Opportunistic infections are common complications after allo-HSCT. Due to the absence of effective preventive and therapeutic drugs for most viruses, viral infections has become one of the most important causes of death. The immunosuppression regimen including ATG has been shown effective to prevent severe GVHD in haploidentical HSCT. But this strategy delays immune reconstitution, and therefore increase the risk of viral infection.

The optimal dose of the different ATG preparations with respect to prevention of GvHD is not fully understood today. The total doses between 6 mg/kg to 15 mg/kg are effective for prevention of GVHD, but the dose above 10 mg/kg may increase the development of viral infection.

In this trial, we will focus on the incidence of aGVHD and viral infections in patients treated with 7.5mg/kg or 10mg/kg of ATG. The incidence of GVHD and viral infections will be compared between different dose arms.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ATGDrug

    ATG will be intravenously infused via a central venous catheter in 3 or 4 days, from day -4 or -3 until day -1. The other conditioning drugs administered before transplantation include cytosine arabinoside (Ara-C), busulfan (Bu),cyclophosphamide (Cy), Semustine(Me-CCNU), and ATG. All transplant recipients will receive cyclosporine A (CsA), mycophenolate mofetil(MMF), and short-term methotrexate for aGVHD prevention.

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Incidence of Epstein-Barr virus(EBV) viremia (time frame: 1 year). 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 NCT01883180, which also lists 6 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 24 Apr 2018; AzTrials last refreshed its copy on 6 Nov 2026.
