Efficacy and Safety of Olverembatinib Plus Inotuzumab Ozogamicin as First-Line Consolidation Therapy Followed by HSCT in Ph+ ALL

February 27, 2026 updated by: Institute of Hematology & Blood Diseases Hospital, China

A Study on the Efficacy and Safety of Olverembatinib Combined With Inotuzumab Ozogamicin as First-Line Consolidation Therapy Bridging to Hematopoietic Stem Cell Transplantation in Patients With Philadelphia Chromosome-Positive Acute Lymphoblastic Leukemia

To study the minimal residual disease (MRD) clearance rate of olverembatinib combined with inotuzumab ozogamicin as first-line consolidation chemotherapy in patients with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL) who have not achieved MRD remission after initial induction chemotherapy.

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

In the previous study, which employed a regimen of olverembatinib combined with inotuzumab ozogamicin to clear MRD in patients with Ph⁺ ALL before bridging to transplantation, the results indicated that this combination achieved a high MRD clearance rate in patients with poor prognosis, along with a high bridging transplantation rate, significantly improving patient outcomes. In the present study, the investigators propose the use of olverembatinib combined with inotuzumab ozogamicin as first-line consolidation therapy. This approach aims to reduce the number of pre-transplant chemotherapy cycles for patients who do not achieve MRD negativity after initial induction chemotherapy, enabling them to attain deeper remission more rapidly. It is expected to provide more transplantation opportunities, including the potential for autologous hematopoietic stem cell transplantation, for this patient population.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • (1) Clearly diagnosed acute lymphoblastic leukemia, with Philadelphia chromosome positivity or BCR-ABL fusion gene positivity; with CD22 expression on the surface of leukemia cells; failure to achieve minimal residual disease (MRD) negativity after first induction chemotherapy (BCR-ABL fusion gene level ≥ 10-⁴), where the induction regimen is standard chemotherapy combined with any tyrosine kinase inhibitor targeting BCR-ABL1.
  • (2) Age greater than or equal to 18 years.
  • (3) Able to provide informed consent independently.
  • (4) Must have adequate organ function: renal and hepatic functions as follows: AST, ALT, and ALP less than 2 times the upper limit of normal (ULN), total bilirubin less than 1.5 times ULN; creatinine clearance greater than 50 mL/min; pancreatic function: serum amylase not exceeding 1.5 times ULN, serum lipase not exceeding 1.5 times ULN; normal cardiac function: ejection fraction (EF) > 60%, pulmonary artery systolic pressure ≤ 50 mmHg.
  • (5) Negative for HIV, HBV, and HCV.
  • (6) Eastern Cooperative Oncology Group Performance Status (ECOG-PS) score of 0-2.
  • (7) Informed consent must be signed before the start of study procedures. For subjects aged 18 years and above, informed consent should be signed by the patient themselves or their immediate family members. Considering the patient's condition, if signing by the patient themselves is detrimental to treatment, the legal guardian or immediate family member may sign the informed consent.

Exclusion Criteria:

  • (1) Mixed lineage leukemia;
  • (2) Involvement of the central nervous system or extramedullary infiltration;
  • (3) Patients with concurrent other malignancies; or those assessed by the investigator as having concomitant diseases that severely endanger the patient's life or affect the completion of the study;
  • (4) Patients with severe allergy to the components or excipients of InO (≥ Grade 3);
  • (5) History of clinically significant liver diseases, such as hepatic veno-occlusive disease (VOD) or sinusoidal obstruction syndrome (SOS); or severe/uncontrolled liver diseases, such as cirrhosis, decompensated liver disease, acute or chronic hepatitis;
  • (6) Active cardiac disease, defined as one or more of the following: history of any cardiac or vascular disease; history of uncontrolled or symptomatic angina; myocardial infarction within 6 months prior to study enrollment; history of arrhythmias requiring medication or with severe clinical symptoms; uncontrolled or symptomatic congestive heart failure (> New York Heart Association [NYHA] Class 2); ejection fraction below the lower limit of normal; pulmonary artery systolic pressure > 50 mmHg on echocardiography; or clinical symptoms related to pulmonary hypertension;
  • (7) History of severe cardiovascular events (including myocardial infarction, unstable angina, severe arrhythmias, congestive heart failure, etc.) during previous tyrosine kinase inhibitor (TKI) treatment for chronic myeloid leukemia (CML);
  • (8) Abnormal coagulation function;
  • (9) Known seropositivity for HIV or active hepatitis C virus;
  • (10) Patients with psychiatric disorders or other conditions that prevent compliance with study treatment and monitoring requirements;
  • (11) Inability or unwillingness to sign the consent form;
  • (12) Pregnant or lactating women;
  • (13) Patients assessed by the investigator as ineligible due to other special circumstances.
