Trial summary

cGVHD is a systemic disease with multi-system damage similar to autoimmune and other immune diseases. It can affect multiple organs such as skin, liver, kidney, and peripheral nerves, causing a serious decline in the quality of life of patients, and death in the late stage of transplantation.

About this study

Official title: Clinical Trial of Umbilical Cord Mesenchymal Stem Cells in the Treatment of Moderate/Severe Chronic Graft-versus-host Disease

cGVHD is a systemic disease with multi-system damage similar to autoimmune and other immune diseases. It can affect multiple organs such as skin, liver, kidney, and peripheral nerves, causing a serious decline in the quality of life of patients, and death in the late stage of transplantation. According to the cGVHD prognostic risk scoring system (revised Risk Group) revised by the European Society for Blood and Bone Marrow Transplantation (EBMT) in 2017, the 3-year survival rate of patients with rRG1 (0-3 points) is about 93.3 ± 6.4%, and rRG2 (4-6 points) about 84.9 ± 3.4%, rRG3 (7-9 points) about 70.9 ± 4.4%, rRG4 (≥10 points) about 32.0 ± 1.1%, it can be seen that moderate to severe cGVHD directly affects the survival of allo-HSCT patients.

Once moderate or severe cGVHD is diagnosed, glucocorticoids with or without calcineurin inhibitor (CNI) are first-line drugs, but the effective rate is less than 50%, and the prognosis of hormone-resistant severe cGVHD is extremely poor even if second-line treatment is added. Second-line treatments include monoclonal antibodies, immunosuppressants, chemotherapy drugs, phototherapy or others. Most of them cannot improve the long-term survival rate. The main reason is that these treatments suppress immunity for a long time, which increases the risk of infection and reduces the survival rate. In this context, the treatment of mesenchymal stromal stem cells (MSCs) provides a new path for clinical treatment of cGVHD.

Read the detailed description

Chronic graft-versus-host disease (cGVHD) refers to the clinicopathological synthesis of lymphocytes from the donor attacking the recipient's organs during the process of rebuilding the donor's immunity after allogeneic hematopoietic stem cell transplantation (allo-HSCT) Signs (including classic cGVHD and overlap syndrome) are one of the main complications after transplantation, with an incidence of 30% to 70%. cGVHD is a systemic disease with multi-system damage similar to autoimmune and other immune diseases. It can affect multiple organs such as skin, liver, kidney, and peripheral nerves, causing a serious decline in the quality of life of patients, and death in the late stage of transplantation. main reason. According to the cGVHD prognostic risk scoring system (revised Risk Group) revised by the European Society for Blood and Bone Marrow Transplantation (EBMT) in 2017, the 3-year survival rate of patients with rRG1 (0-3 points) is about 93.3 ± 6.4%, and rRG2 (4-6 points) About 84.9 ± 3.4%, rRG3 (7-9 points) about 70.9 ± 4.4%, rRG4 (≥10 points) about 32.0 ± 1.1%, it can be seen that moderate to severe cGVHD directly affects the survival of allo-HSCT patients.

Once moderate or severe cGVHD is diagnosed, glucocorticoids with or without calcineurin inhibitor (CNI) are first-line drugs, but the effective rate is less than 50%, and the prognosis of hormone-resistant severe cGVHD is extremely poor even if second-line treatment is added. Second-line treatments include monoclonal antibodies, immunosuppressants, chemotherapy drugs, phototherapy or others. Most of them cannot improve the long-term survival rate. The main reason is that these treatments suppress immunity for a long time, which increases the risk of infection and reduces the survival rate. In this context, the treatment of mesenchymal stromal stem cells (MSCs) provides a new path for clinical treatment of cGVHD.

In 2002, Frassoni reported for the first time that MSCs expanded in vitro were used to evaluate the efficacy of allo-HSCT. Allo-HSCT transplanted patients with hematological malignancies were enrolled. MSCs were derived from the donor's bone marrow. After expanded in vitro, participants were combined with the donor's hematopoietic stem cells for reinfusion. As a result, the incidence of aGVHD in the MSCs expansion group and cGVHD within 6 months was significantly lower in the control group, the 6-month OS was significantly higher than that in the control group, and there was no significant difference in the recurrence rate. Subsequently, in 2004, Le Blanc and others successfully used third-party MSCs to successfully treat a refractory grade IV intestinal combined with liver aGVHD for the first time. Subsequently, MSCs were increasingly used in clinical studies for the treatment of GVHD. More clinical trials have shown that umbilical cord-derived MSCs cultured in vitro can not only promote the implantation of hematopoietic stem cells (HSC), but also reduce the incidence of severe GVHD in patients, showing a good therapeutic effect.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Umbilical Cord Mesenchymal Stem Cell Therapy in people with Graft Vs Host Disease, run by Shenzhen University 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 5 inclusion and 14 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 9 Dec 2021. 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 Li Yu (+8675521839178, liyu@vip.163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Disease-related clinical reactions (time frame: Change frome baseline clinical manifestationc of cGVHD at 8 weeks). 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 9 Dec 2021.
