A Study of Olverembatinib Combined With Inotuzumab Ozogamicin in the Treatment ph+ ALL With MRD Persistent Positive
October 30, 2022 updated by: Institute of Hematology & Blood Diseases Hospital
A Prospective, Single-arm, Multi-center Study of Olverembatinib Combined With Inotuzumab Ozogamicin in the Treatment ph+ ALL With MRD Persistent Positive
Hematopoietic stem cell transplantation (HSCT) is the effective and even the only cure treatment option for ph+ acute lymphocyte leukemia (ph+ALL).
However, the outcome has been insufficient and relapse remains the major cause of treatment failure and poor survival, especially for patients with persistent minimal residual disease (MRD).
It is believed that clearance of MRD pre-HSCT could significantly reduce the incidence of relapse post-HSCT.
Olverembatinib has been documented as a promising third generation of TKIs.
Meanwhile, Inotuzumab ozogamicin (InO) , an antibody-drug conjugate approved in the US and the European Union, has been applied in relapsed/refractory acute lymphoblastic leukemia (R/R ALL) and achieved good treatment outcome.
This prospective, single arm and multicenter study is to investigate the efficacy and safety of combination of Olverembatinib and Ino for MRD clearance before bridging to HSCT.

Description
Inclusion Criteria:
- Acute lymphoblastic leukemia with positive Ph chromosome or BCR / ABL fusion gene ; cD22 expression on the surface of leukemia cells ; hematological complete remission but with MRD persistent positive ( BCR-ABL1 level ≥ 10-4 ), after at least 3 times of intensive chemotherapy, in which classical chemotherapy combined with any first or second generation of tyrosine kinase inhibitors targeting BCR-ABL1.
- Be ≥ 18 years of age on the day of enrollment.
- Understand the study procedures, alternative treatment available, and risks involved with the study, and voluntarily agree to participate by giving written informed consent.
- Necessary to meet the criteria of important organ function : renal function and liver function are as follows : AST, ALT and ALP below the normal 2 times the upper limit, total bilirubin below the normal upper limit 1.5 times ; creatinine clearance rate greater than 50ML / min ; pancreatic function : serum amylase is not higher than the normal upper limit 1.5 times, serum lipase is not higher than the normal upper limit 1.5 times ; normal heart function : ejection fraction ( EF ) > 60 %, pulmonary artery systolic pressure ≤ 50mmHg.

- ECOG-PS 0-2.
- Informed consent must be signed before the start of the trial. Informed consent must be signed by the patient himself or his direct family members who are 18 years old and above ; considering the patient 's condition, if the patient 's signature is not conducive to the treatment of the disease, the informed consent is signed by the legal guardian or the patient 's immediate family.
Exclusion Criteria:

- Patients received radiotherapy or chemotherapy (except induction chemotherapy ) or any other research treatment within two weeks before enrollment, with the following exceptions :Designed to reduce circulating leukemia lymphocytes count or remission : Steroids, hydroxyurea or vincristine;Maintenance therapy : thiopurine, methotrexate, vincristine, thioguanine and / or tyrosine kinase inhibitors.
- Patients with severe allergies to InO components and excipients ( Grade ≥ 3 ).
- History of clinically significant liver disease, such as hepatic veno - occlusive disease ( VOD ) or sinusoidal obstruction syndrome ( SOS ) ; such as cirrhosis, decompensated liver disease, acute or chronic hepatitis.
- Active heart disease, defined as one or more of the following : with any history of heart or vascular disease ; have uncontrolled or symptomatic angina history ; myocardial infarction less than 6 months before enrollment ; a history of arrhythmia requiring drug treatment or severe clinical symptoms ; uncontrolled or symptomatic congestive heart failure ( > NYHA grade 2 ) ; ejection fraction is below the lower limit of the normal range. Cardiac ultrasound pulmonary artery systolic pressure > 50mmHg ; or pulmonary hypertension - related clinical symptoms.
- Severe cardiovascular disease, including myocardial infarction, unstable angina, severe arrhythmia, congestive heart failure, etc. during previous TKI treatment.

The ratio of patients achieved MRD remission.
The MRD remission was defined as the fusion gene BCR-ABL quantification in bone marrow samples was lower than the detection limit of RT-PCR ( < 0.01 %, the residual number of leukemia cells detected in our hospital was 0.0032 % ) ; at the same time, flow cytometry ( FACS ) was used to monitor the MRD of the cells, and the proportion of abnormal cells < 0.1 % was MRD-
