About this study
Official title: Shanghai General Hospital Affiliated to Shanghai Jiao Tong University
A novel regimen, which is composed of a low dose of ATG (5 mg/kg) and low-dose PTCy (one dose of PTCy, 50mg/kg) for GvHD prophylaxis in Haplo-PBSCT for patients with hematologic malignancies, was designed to decrease the risk of aGvHD and lower the incidence of virus reactivation.
Read the detailed description
Acute graft-versus-host disease (aGvHD) is the most important obstacle of haploidentical hematopoietic stem cell transplantation (Haplo-HSCT) for treatment of patients with hematologic malignancies. In the last two decades, the results of Haplo-HSCT have been conspicuously improved due to effective prophylaxis strategies for aGvHD, such as in vivo T cell depletion (TCD) with anti-thymocyte globulin (ATG) or post-transplant cyclophosphamide (PTCy).
The regimens for prophylaxis of GvHD based on rabbit anti-human thymocyte immunoglobin (ATG 10mg/kg, Thymoglobin®, Genzyme Polyclonals S.A.S) effectively prevented the occurrence of grade II-IV aGvHD with an incidence of 33.4%-46%, grade III-IV aGvHD 12%-14.9%, but the reactivation incidences of cytomegalovirus (CMV) and EB virus (EBV) were higher due to a slower immune reconstitution(2-4). The 100-day CIs of CMV and EBV viremia were 61%-64%and over 50%, respectively. Although ATG-based regimens have achieved excellent results, the incidences of aGvHD and the post-transplant virus reactivation are still higher, affecting the long-term survival of the patients.
The regimen of PTCy for prevention of GvHD was developed in 1999 by St. Johns Hopkin's group in Baltimore (1) and had outstanding results with the CIs of 34% grades II-IV and of 6% grades III-IV aGvHD by day 200 in haplo-bone marrow transplantation (Haplo-BMT) (7), respectively. The incidences of viral and fungal infection in Haplo-HSCT with PTCy for GvHD prophylaxis were much lower than ATG based regimens. Ruggeri A（8）et al retrospectively analyzed the effects of different stem cell source (BM vs PBSC) on the transplant results in Haplo-HSCT with PTCy. The results showed that BM was associated with a lower incidence of grades II-IV and grades III-IV acute GVHD (21% vs 38%, P ≤ .01; and 4% vs 14%, P < .01, respectively), which was further confirmed by Bashey A et al' study（9）. These data indicated that PTCy regimen don't have the same effects for GvHD prophylaxis with PBSC graft as compared with BM graft in Haplo-HSCT.
A novel regimen, which is composed of a low dose of ATG (5 mg/kg) and low-dose PTCy (one dose of PTCy, 50mg/kg) for GvHD prophylaxis in Haplo-PBSCT for patients with hematologic malignancies, was designed to decrease the risk of aGvHD and lower the incidence of virus reactivation. A prospective, phase II clinical trial (Clinicaltrials.org NCT03395860) was performed to evaluate the efficacy with low dose ATG followed by low dose PTCy as GvHD prophylaxis.Thirty-two patients diagnosed with hematological malignancies were enrolled in this trial. All patients received myeloablative conditioning regimens except for three patients. The cumulative incidences (CIs) of grades II-IV and III-IV acute GvHD were 19.4% (95% CI, 5.5-33.3%) and 6.9% (95% CI 0-16.3%) by day 100, respectively. The one-year probability of relapse was 25.1% (95% CI, 7.3-42.9%). The one-year probabilities of disease free-survival (DFS) and overall survival (OS) was 59% (95% CI, 33.3%-84.7%) and 78.4% (95% CI, 63%-93.8%), respectively. The CIs of CMV reactivation and EBV reactivation by day 180 were 37.5% (95% CI, 19.8-55.2%) and 40.6% (95% CI, 22.6-58.6%), respectively. The results suggested that low dose ATG with low dose PTCy as GvHD prophylaxis in Haplo-PBSCT had promising activity. A prospective randomized trial is required to compare the efficacies of this regimen with ATG-based or PTCy-based regiments in Haplo-PBSCT.

MMF was administered at 15 mg/kg oral 3 times per day (maximum dose 3g per day) until day +35 and was then stopped if no aGvHD. Mycophenolate Sodium Enteric-coated Tablets (MPA) can be used instead of MMF, one tablet MPA corresponds to one tablet MMF. CsA was tapered from day +90 to day +180. |

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing ATG/PTCy, standard ATG and standard PTCy in people with Myeloid Tumor, run by Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine at 6 sites 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 6 inclusion and 7 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: finished, as of the sponsor's last update on 5 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites 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 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?
The cumulative incidences of acute GVHD (time frame: 100 days 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 NCT03608059, which also lists 14 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 5 Oct 2023.
