Venetoclax+Azacytidine+Modified BUCY Conditioning Regimen for Acute Lymphoblastic Leukemia Undergoing Allo-HSCT

April 10, 2023 updated by: The First Affiliated Hospital of Soochow University

Venetoclax (VEN)+Azacytidine (AZA) Followed by Modified BUCY Conditioning Regimen for High Risk or Refractory/Relapsed Acute Lymphoblastic Leukemia Undergoing Allogeneic Hematopoietic Stem Cell Transplantation (Allo-HSCT)

The purpose of this prospective, open-label, single-center study is to evaluate the efficacy and safety of VEN-AZA (venetoclax and azacytidine) followed by modified BUCY (busulfan and cyclophosphamide) as conditioning regimen for high-risk or relapsed/refractory acute lymphoblastic leukemia (ALL) undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Allogeneic hematopoietic stem cell transplantation (Allo-HSCT) is the only potentially curative therapy for patients with acute lymphoblastic leukemia. However, relapse remains a leading cause for treatment failure after hematopoietic cell transplantation (HCT) in patients, optimization of conditioning regimen can improve prognosis and decrease relapse. Abnormal gene methylation is common in ALL patients. Azacytidine is a DNA methylation transferase inhibitor that can re-express tumor suppressor genes in leukemia cells. Venetoclax is a selective BCL-2 inhibitor, which has antitumor activity against a variety of hematological malignancies. The combination of the two drugs show a synergistic anti-tumor effect. Multiple case reports the efficacy of Venetoclax-based regimens in patients with ALL is encouraging. The objective of this study is to evaluate the feasibility, safety and efficacy of VEN-AZA bridging allogeneic hematopoietic stem cell transplantation in the treatment of high-risk ALL.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
55

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Age 14 to 65 years;
  2. Diagnosis of high-risk or relapsed/refractory acute lymphoblastic leukemia at the time of transplant.
  3. Must need a bone marrow transplant;
  4. Must have the ability to observe the efficacy and events;
  5. Patient must have ability to understand and willingness to provide written informed consent prior to participation in the study and any related procedures being performed.

Exclusion Criteria:

  1. Age <14 or >65 years;
  2. Uncontrolled bacterial, viral, fungal, or other infection before conditioning regimen;
  3. Pregnant or lactating females;
  4. Current participation in another clinical trial;
  5. Contra-indication to one of the drug of the regimen;
  6. Any other severe concurrent disease, or have a history of serious organ dysfunction or disease involving the heart, kidney, liver or other organ system that may place the patient at undue risk to undergo the agents included in the conditioning regimen

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
disease-free survival (DFS)
Time Frame: 3 years after transplantation
It is measured from the time from randomization to the first of relapse or death.
3 years after transplantation
overall survival (OS)
Time Frame: 3 years after transplantation
It is measured from the time of entry into this trial to the date of death from any cause; patients not known to have died at last follow-up are censored on the date they were last known to be alive.
3 years after transplantation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
veno-occlusive disease (VOD)
Time Frame: 3 years after transplantation
incidence of veno-occlusive disease (VOD) events (refer to modified Seattle Criteria of VOD)
3 years after transplantation
graft-versus-host disease (GvHD)
Time Frame: 3 years after transplantation
incidence and severity of acute (aGvHD) and chronic graft-versus-host disease (cGvHD) (aGvHD refer to Glucksberg Criteria and cGvHD refer to the National Institutes of Health Consensus)
