Blinatumomab plus low-dose donor cells after transplant for high-risk B-ALL

Official title: A Single-arm, Open-label, Phase I Clinical Study of Blinatumomab Combined With Low-dose DLI as Maintenance Therapy After Transplantation for B-ALL

Run by Chinese PLA General Hospital · NCT07677878 · Data updated 2026-11-12

This small, early-phase study tests whether giving blinatumomab with low-dose donor lymphocytes after allogeneic transplant is safe and helps long-term survival for people with high-risk B-ALL.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults under 70 with high-risk B-ALL who are MRD-negative after allo-HSCT and have engrafted allogeneic transplants from related or unrelated donors.

Probably not a fit

Patients with poor engraftment, active infections, or contraindications to immunotherapy may not benefit and could experience adverse events.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a single-center, prospective, single-arm Phase I trial in adults under 70 with high-risk B-ALL who have recently undergone allogeneic stem cell transplantation. Participants receive a maintenance regimen of blinatumomab followed by low-dose donor lymphocyte infusions at set intervals within the first year post-transplant, with dexamethasone premedication before each cycle. The study aims to assess safety and preliminary efficacy, including disease control and survival trends, in a structured, closely monitored setting. Enrollment criteria require MRD-negative status post-transplant, adequate organ function, and performance status suitable for maintenance therapy.

Why it matters

Potential benefit: If successful, the approach could reduce relapse risk and improve long-term survival after transplant.

How similar studies have gone: The use of blinatumomab with DLI is a exploratory combination; prior similar approaches have shown signals but require confirmation in larger trials.
