Measured: Follow-up until 3 years after transplantation
Secondary outcomes (3)
NGS-MRD response rate
Bone marrow was collected from patients at 3 and 6 months after transplantation and at 15 days after treatment with blinatumomab, and immunoglobulin rearranged IGH-VDJ sequences were monitored using high-throughput sequencing (NGS) to identify significant clonal sequences to regularly determine changes in MRD levels before and after treatment.
Measured: 3 and 6 months after transplantation and at 15 days after treatment
overall survival (OS)
overall survival (OS)
Measured: Follow-up until 3 years after transplantation
incidence of acute and chronic GVHD
The frequency and severity of acute GVHD of the intestine, skin, and liver were observed until 100 days after transplantation, and all episodes of GVHD were graded using the clinical grading criteria for acute GVHD. The changes of skin, liver function, eyes, and oral cavity of patients after 100 days after transplantation were observed to assess the incidence of localized and extensive chronic GVHD.
Measured: 100 days after transplantation

Who may be eligible to take part?
The sponsor lists 7 inclusion and 1 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 16 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.
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.
Are results available for this study?
