Blinatumomab and Auto-HSCT Sandwich Strategy as Consolidation Therapy for B-ALL
A Phase 1 study testing blinatumomab and auto-HSCT "sandwich " strategy in people with B-cell Acute Lymphoblastic Leukemia, run by The First Affiliated Hospital of Soochow University at 1 site in China.
Trial summary
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the main method potentially curing adult B-ALL, but the high treatment-related mortality (NRM) affects overall survival (OS). Autologous stem cell transplantation (auto-HSCT) can significantly reduce NRM but has a higher relapse rate. Read more about this study

About this study
Official title: Safety and Efficacy of Blinatumomab and Autologous HSCT Sandwich Strategy as Consolidation Therapy for B-cell Acute Lymphoblastic Leukemia
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the main method potentially curing adult B-ALL, but the high treatment-related mortality (NRM) affects overall survival (OS). Autologous stem cell transplantation (auto-HSCT) can significantly reduce NRM but has a higher relapse rate. Studies have confirmed that achieving MRD negativity before Auto-HSCT can effectively reduce post-transplant relapse, achieving similar efficacy to allo-HSCT. The efficacy of blinatumomab in clearing MRD has been confirmed. Therefore, using blinatumomab combined with Auto-HSCT for B-ALL patients seems to make it possible to achieve benefits in leukemia free survival（LFS） and OS. The investigators first conducted blinatumomab and auto-HSCT "sandwich " strategy as consolidation therapy in patients with B-ALL. The main Purpose of this study was to observe the safety and efficacy of this new strategy.
Read the detailed description
Enrolled patients received induction chemotherapy with the IVP regimen and two cycles of consolidation chemotherapy: high-dose cytarabine (Ara-c) + pegaspargase (± Tyrosine kinase inhibitors ,TKI) and methotrexate (MTX) + pegaspargase (± TKI). Sequential treatment with blinatumomab was then administered. After the first treatment with blinatumomab, autologous stem cell mobilization and collection were performed. Following successful stem cell collection, autologous stem cell transplantation was conducted. Starting from the third month after autologous stem cell transplantation, the second maintenance treatment with blinatumomab was administered, with one cycle every three months, for a total of four cycles. Long-term follow-up monitoring was then conducted. The follow-up period for this study was two years, and data on two-year LFS, OS, and NRM rates were collected.

What participants receive

blinatumomab and auto-HSCT "sandwich " strategyCombination product
The patients received sequential infusion of blinatumomab after standard induction and consolidation chemotherapy. Autologous stem cells mobilization and collection were performed 6-8 weeks after infusion. Following successful stem cell collection, autologous stem cell transplantation was conducted. Starting from the third month after autologous stem cell transplantation, the second maintenance treatment with brentuximab vedotin was administered, with one cycle every three months, for a total of four cycles. Patients were followed up and minimal residual diseases (MRD) was monitored by flow cytometry and second-generation gene sequencing of IgH rearrangement.

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 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.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall survival（OS） (time frame: 4 years). The study lists 2 primary outcomes in all. 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 NCT06507514, which also lists 1 linked publication.
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 21 Nov 2025.
