What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 30 participants in total. It began in 2024-08-06 with a primary completion date of 2027-01-01.

Brief Summary

To find the recommended doses of lisaftoclax and olverembatinib that can be given in combination with decitabine to participants with advanced CML and Ph+ AML.

Eligibility Criteria

Inclusion Criteria: a) Diagnosis: Age ≥18 years with CML-AP, CML-MBP, or Ph+ AML by WHO 2016 criteria. * Participants must have been intolerant or resistant to at least one prior BCR::ABL1 TKI 2\. Performance status ≤3 (ECOG Scale). 3\. Adequate liver, cardiac, renal and pancreatic function as defined by the following criteria: 1. Total serum bilirubin \< 1.5 x upper limit of normal (ULN), unless due to Gilbert's syndrome, hemolysis or the underlying leukemia approved by the PI 2. Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \< 3 x ULN, unless due to the underlying leukemia approved by the PI 3. Creatinine clearance ≥30 mL/min 4. Serum amylase or lipase \< 1.5 x ULN 4\. Ability to understand and the willingness to sign a written informed consent document 5\. Willingness to use adequate contraception prior to study entry, for the duration of study participation, and for 6 months after completion of study participation. For women of child-bearing potential, adequate methods of contraception include: complete abstinence,, hormonal contraception (i.e. birth control pills, injection, implant, transdermal patch, vaginal ring), intrauterine device (IUD), tubal Ligation or hysterectomy, subject/partner post vasectomy, implantable or injectable contraceptives, and condoms plus spermicide. Exclusion Criteria: 1. Participants who have previously received lisaftoclax or olverembatinib 2. History of acute pancreatitis within 1 year of study or history of chronic pancreatitis 3. Active grade III-V cardiac failure as defined by the New York Heart Association Criteria 4. Clinically significant and uncontrolled cardiovascular disease, including but not restricted to: i. Myocardial infarction (MI), stroke, revascularization, unstable angina, or transient ischemic attack within 6 months. ii. Left ventricular ejection fraction (LVEF) less than lower limit of normal per local institutional standards prior to enrollment. iii. Diagnosed or suspected congenital long QT syndrome. iv. Clinically significant atrial or ventricular arrhythmias (such as uncontrolled, clinically significant atrial fibrillation, ventricular tachycardia, ventricular fibrillation, or Torsades de pointes) as determined by the treating physician. v. Prolonged QTc interval on pre-entry electrocardiogram (\> 480 msec) unless corrected after electrolyte replacement. vi. History of venous thromboembolism including deep venous thrombosis or pulmonary embolism within the past 3 months, excluding line associated DVT of the upper extremity vii. Uncontrolled hypertension (diastolic blood pressure \>100mmHg; and systolic \>150mmHg). 5. Active serious infection not controlled by oral or intravenous antibiotics (e.g. persistent fever or lack of improvement despite antimicrobial treatment). 6. Active central nervous system leukemia 7. Known human immunodeficiency virus (HIV) seropositive, unless well-controlled on stable doses of anti-retroviral therapy. 8. Known hepatitis B surface antigen seropositive or known or suspected active hepatitis C infection Note: Participants who have isolated positive hepatitis B core antibody (ie, in the setting of negative hepatitis B surface antigen and negative hepatitis B surface antibody) must have an undetectable hepatitis B viral load. Participants who have positive hepatitis C antibody may be included if they have an undetectable hepatitis C viral load. 9. Participants with a prior or concurrent malignancy whose natural history or treatment is not anticipated to interfere with the safety or efficacy assessment of the investigational regimen may be included only after discussion with the PI 10. Consumed strong inducer of CYP3A or p-glycoprotein within 14 days of study enrollment, or 5 half-lives, whichever is longer. Agents include but are not limited to: carbamazepine, phenytoin, rifampin, and St. John's wart 11. Treatment with any investigational antileukemic agents or chemotherapy agents in the last 7 days before study entry, unless full recovery from side effects has occurred or patient has rapidly progressive disease judged to be life-threatening by the investigator. Prior recent treatment with corticosteroids, hydroxyurea, cytarabine (up to 2 g/m2 given for cytoreduction within the preceding 7 days) and/or an FDA-approved BCR::ABL1 TKI is permitted. 12. Inability to swallow 13. Pregnant or breastfeeding women will not be eligible 14. History of allergic reactions attributed to compounds of similar chemical or biologic composition to Decitabine, Lisaftoclax, and Olverembatinib or other agents used in study. 15. Participants with psychiatric illness/social situations that would limit compliance with study requirements.
