About this study

Official title: Prospective Study of Combined 4-Day ATG Regimen for Prophylaxis of aGVHD in Matched Sibling Donor PBSCT

The purpose of this study is to determine the efficacy and safety of combined ATG #antithymocyte globulin # regimen (5mg/kg divided from day -5 to day -2) for aGVHD(acute graft-versus-host disease ) prophylaxis in matched sibling donor peripheral blood stem cell transplantation (MSD-PBSCT).

Read the detailed description

Transplantation with G-CSF #Granulocyte colony stimulating factor #mobilized peripheral blood stem cell (PBSCT) has been a stable transplant setting with matched sibling donor transplantation. Unmanipulated haploidentical donor PBSCT (haplo-PBSCT) has been applied in patients with hematologic malignancies. In our previous cohort study, haplo-PBSCT was associated with lower incidence of severe acute GVHD and extensive chronic GVHD compared with matched sibling donor PBSCT (MSD-PBSCT). Haplo-PBSCT has the same GVHD prophylaxis regimen with MSD-PBSCT, except ATG. It suggested the potential advantage of ATG in prophylaxis of GVHD and improvement of long term quality of life of the transplant recipients, which motivate us to observe the efficacy of combined ATG regimen for GVHD prophylaxis in MSD-PBSCT.

What participants receive

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

  • Rabbit ATGDrug

    Also called Thymoglobuline

    ATG (Thymoglobuline, rabbit) was used as 1 mg/kg/d from day -5 to day -3 and 2 mg/kg/d on day -2.

Study groups in NCT05214066
Study groupRoleWhat they receive
4-day ATG combined regimenExperimentalATG combined regimen for prophylaxis of GVHD, includes ATG, MMF (Mycophenolate mofetil), CsA (cyclosporin A) and MTX (methotrexate). All recipients in this arm received ATG, CsA, mycophenolate mofetil, and short-term methotrexate for GVHD prophylaxis. ATG (Thymoglobuline, rabbit) was used as 1 mg/kg/d from day -5 to day -3 and 2 mg/kg/d on day -2. CsA (3 mg/kg, q12h, i.v.) was used from day -9, and the concentration was adjusted to 180-200 ng/mL. CsA was switched to oral administration when the patient's bowel function recovered. From day -9, 0.5 g of mycophenolate mofetil was administered orally from every 12 h, which was withdrawn on day +30. After graft infusion, MTX was given for all patients at 15 mg/m2 on day +1 and 10 mg/m2 on days +3, +6 and +11.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Rabbit ATG in people with aGVHD and cGVHD, run by Chinese PLA General Hospital at 1 site in China.

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 4 inclusion and 2 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 22 Feb 2022. 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.

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?

Results are not available in the source record.

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

Contact Daihong Liu, Doctor (+8613681171597, daihongrm@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants with severe cGVHD (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Feb 2022.
