Impact of Low-intensity Chemotherapy Combined With Short-course Blinatumomab on Allo-HSCT in Adults With Ph- B-ALL

45 participantsStarted 2025-09-01

Plain-language summary

This single-arm, prospective, multicenter, phase II study will enroll newly diagnosed Philadelphia chromosome-negative (Ph-) acute B-cell lymphoblastic leukemia (B-ALL) patients aged 18-60 years. Participants will receive sequential low-intensity chemotherapy followed by a two-week blinatumomab induction therapy. Treatment Protocol 1. Low-intensity chemotherapy (VIP regimen) * V (Vincristine): 1.4 mg/m² (max 2 mg) on days 1 and 8. * I (Idarubicin): 8 mg/m²/day on days 1 and 8. * P (Prednisone): 60 mg/m²/day (max 100 mg/day) or equivalent dexamethasone dose on days 1-14. 2. Sequential induction therapy: * Blinatumomab administered for 2 weeks following the VIP regimen. 3. Consolidation therapy for morphological complete remission (CR) * Patients achieving CR receive two cycles of consolidation chemotherapy: * Cycle 1: VDCP regimen (Vincristine, Daunorubicin, Cyclophosphamide, Prednisone). * Cycle 2: VP + HD-MTX regimen (Vincristine, Prednisone + High-Dose Methotrexate). 4. Allogeneic hematopoietic stem cell transplantation (allo-HSCT): * Patients with multiparameter flow cytometry-confirmed minimal residual disease (MRD)-negative status proceed to allo-HSCT. Patients achieving morphological complete remission (CR) will undergo two cycles of consolidation chemotherapy. Those with minimal residual disease (MRD)-negative status confirmed by multiparameter flow cytometry (MFC) or next-generation sequencing (NGS) will proceed to allogeneic hematopoietic stem cell transplantation (allo-HSCT). The primary endpoint is 18-month relapse-free survival (RFS) rate, the secondary endpoints were composite response rate (CRc: CR + CR with incomplete hematologic recovery \[CRi\]), MRD-negative rate (assessed by MFC/NGS),18-month overall survival (OS) post-transplant, non-relapse mortality (NRM), cumulative incidence of acute/chronic graft-versus-host disease (GVHD), cumulative relapse rate and 18-month GVHD-free/relapse-free survival (GRFS) post-transplant.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
