About this study

Official title: Clinical Study on the Efficacy and Safety of Reduced-Dose Chemotherapy Followed by 14 Days of Blinatumomab in Adult Patients with Newly Diagnosed Ph-Negative B-ALL: a Prospective, Multicenter, Observational Study.

This is a prospective, multicenter, observational study aimed at exploring the efficacy and safety of reduced-dose chemotherapy followed by frontline therapy with blinatumomab in patients aged 15-65 with newly diagnosed Ph-negative B-ALL.

Read the detailed description

The 14-day blinatumomab combined with reduced-dose chemotherapy is used for the induction treatment of newly diagnosed Ph-chromosome negative acute B-lymphoblastic leukemia. On day 14, an intrathecal injection of chemotherapy is administered; on days 28-35, bone marrow is assessed, and patients who do not achieve complete remission are withdrawn from the study. Patients with positive minimal residual disease (MRD) after induction treatment undergo transplant typing and proceed to allogeneic hematopoietic stem cell transplantation (Allo-HSCT) after early intensification. Patients with negative MRD receive alternating treatment with multi-drug combination chemotherapy and blinatumomab, for a total of 8 consolidation courses, including 3 courses of blinatumomab. Maintenance therapy lasts for at least 18 months, using the POMP regimen with or without one cycle of blinatumomab every six months. Throughout the entire treatment phase, at least 12 preventive intrathecal injections are administered.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The overall response rate

    The overall response rate after induction therapy = Complete Remission (CR) + CR with partial hematologic recovery (CRh) + CR with incomplete hematologic recovery (Cri).

    Measured: At the end of induction treatment from day 28 to day 35

  2. Minimal Residual Disease (MRD) negativity rate after induction therapy

    MRD negativity refers to a flow cytometry test result where MRD is less than 0.01%.

    Measured: At the end of induction treatment from day 28 to day 35

Secondary outcomes (4)
  1. Complete molecular remission rate.

    Complete molecular remission rate is defined as undetectable Ig rearrangement by next-generation sequencing, with a detection sensitivity of at least less than 10^-5.

    Measured: At the end of induction treatment from day 28 to day 35

  2. One-year overall survival rate.

    The proportion of patients who are still alive one year after the date of disease diagnosis, out of the total number of subjects enrolled in the study.

    Measured: From diagnosis of the disease to the end of the first year

  3. One-year event-free survival rate

    The proportion of patients who have not experienced disease progression, been diagnosed with another cancer, or died from any cause one year after the date of disease diagnosis, out of the total number of subjects enrolled in the study.

    Measured: From diagnosis of the disease to the end of the first year

  4. Safety

    Safety endpoints are defined, graded, and evaluated according to the CTCAE version 5.0 criteria.

    Measured: From enrollment until withdrawal from the study or the end of follow-up up to two years

The record says: opening soon, as of the sponsor's last update on 18 Oct 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?

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?

Contact Yanping Sun (18560089133, syp215920@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The overall response rate (time frame: At the end of induction treatment from day 28 to day 35). 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 NCT06649422, 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?
