What is being measured

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

  1. Overall survival (OS)

    All patients will be tracked from Day 0 to date of first objective disease progression, death from any cause, or last patient evaluation. Patients who have not progressed or died will be censored at the last date they were assessed and deemed free of relapse or progression.

    Measured: 2 years

Secondary outcomes (6)
  1. Progression-free survival (PFS)

    All patients will be tracked from Day 0 to date of first objective disease progression, death from any cause, or last patient evaluation. Patients who have not progressed or died will be censored at the last date they were assessed and deemed free of relapse or progression.

    Measured: 2 years

  2. Cumulative incidence of transplant-related nonrelapse mortality (NRM)

    All patients will be tracked from Day 0 to date of first objective disease progression, death from any cause, or last patient evaluation. Patients who have not progressed or died will be censored at the last date they were assessed and deemed free of relapse or progression.

    Measured: 2 years

  3. Cumulative incidence of disease relapse or progression

    All patients will be tracked from Day 0 to date of first objective disease progression, death from any cause, or last patient evaluation. Patients who have not progressed or died will be censored at the last date they were assessed and deemed free of relapse or progression.

    Measured: 2 years

  4. GVHD-free, relapse-free survival (GRFS)

    All patients will be tracked from Day 0 to date of first objective disease progression, death from any cause, or last patient evaluation. Patients who have not progressed or died will be censored at the last date they were assessed and deemed free of relapse or progression.

    GRFS is defined as survival with no evidence of relapse/progression, grade III to IV aGVHD, and systemic therapy-requiring cGVHD.

    Measured: 2 years

  5. Cumulative incidence of total acute and grade II-IV acute GVHD

    Date of symptom onset, maximum clinical grade, and dates and types of treatment will be recorded. Dates of symptom onset of grade II or higher acute GVHD and grade III-IV acute GVHD will be recorded.

    Measured: 180 days

  6. Cumulative incidence of total and and moderate-severe chronic GVHD

    Date of symptom onset, maximum clinical grade, and dates and types of treatment will be recorded. Dates of symptom onset of chronic GVHD and severe chronic GVHD will be recorded.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Cytarabine, Busulfan and Cyclophosphamide in people with Leukemia and MDS, run by First Affiliated Hospital of Zhejiang University at 8 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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: under way, not looking for participants, as of the sponsor's last update on 9 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall survival (OS) (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Apr 2026.
