About this study

Official title: Safety and Efficacy Study of Autologous Nonmyeloablative Hematopoietic Stem Cell Transplantation for Early Onset Type 1 Diabetes-a Phase II Study

This is a phase II trial in individuals who have been diagnosed with type 1 diabetes within the previous 6 months. The study is evaluating whether stem cell transplantation is safe when chemotherapy and immunotherapy are used in combination and if it has immune resetting effect that may halt the immune attack to pancreas islets and thus preserve the body's own insulin production.

Read the detailed description

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks the insulin-producing beta cells in the pancreas. Generally, at the time someone is diagnosed with type 1 diabetes, not all of a person's beta cells have been destroyed. It's important to preserving the remaining precious beta cells so as to stop the diabetes progression.

The exact mechanism of action of Autologous Hematopoietic Stem Cell Transplantation(AHST) in autoimmune disorders is not fully understood. Preliminary data supported post-AHST immune resetting included an increase in thymus-derived naive T cells, decreased central-memory T cells, increased output of recent thymic emigrants, and recovery of a diverse but distinct T-cell receptor repertoire following AHST. In the patients of type 1 diabetes, decreasing titer of anti-GAD antibody may bring improvement of beta-cell function after intensive immunosuppression. Furthermore, there may exit the possibility of regeneration of beta cells from surviving beta cells or from pancreatic or bone marrow stem cells.

Patients recently diagnosed (less than 6 months) with type 1 diabetes mellitus proved by positive antibody against glutamic acid decarboxylase will be included in this study. Hematopoietic stem cells will be mobilized with cyclophosphamide (2.0 g/m2) and granulocyte colonystimulating factor (10 μg/kg per day) and then collected from peripheral blood by leukapheresis and cryopreserved. The cells were injected intravenously after conditioning with cyclophosphamide (200 mg/kg) and rabbit antithymocyte globulin (4.5 mg/kg). This procedure is performed in isolated rooms at the Bone Marrow Transplantation Unit of Shanghai Ruijin Hospital affiliated to Shanghai Jiao-Tong University School of Medicine. Patients will be discharged from the hospital 1 month after transplantation and continue the follow-ups for 3 years. Patients fitting the inclusion criteria but not agreeing to perform the transplantation are the control group and they will be followed in parallel with transplanted patients.

  • Insulin therapyDrug

    Also called insulin injection therapy

    All study participants not accepted written informed consent will received insulin therapy with consistent or multiply subcutaneous injection.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing AHSCT and Insulin therapy in people with Type 1 Diabetes Mellitus, run by Shanghai Jiao Tong University School of Medicine 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 2 inclusion and 6 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 18 Nov 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 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?

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?

Exogenous insulin dose (time frame: 1 month, 3 months, 6 months, 12 months, 24 months, 36 months). 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 NCT00807651, which also lists 4 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 18 Nov 2021.
