Ibrutinib, Idarubicin and Cytarabine in Treating Patients With Relapsed or Refractory Acute Myeloid Leukemia

Stopped early · Phase 1

Conditions studied: Recurrent Adult Acute Myeloid Leukemia

In brief

This phase I trial studies the side effects and best dose of ibrutinib when given together with idarubicin and cytarabine in treating patients with acute myeloid leukemia that has returned after a period of improvement or has not responded to previous treatment. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as idarubicin and cytarabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ibrutinib together with idarubicin and cytarabine may kill more cancer cells.

You may qualify if…

• Previous morphologically-confirmed diagnosis of acute myeloid leukemia (AML) based on World Health Organization (WHO) Criteria
• At least one prior chemotherapy regimen to treat AML
• Disease relapse or refractory disease as shown by > 5% blasts in the bone marrow (not attributable to another cause). Administration of hydrea to control high WBC count is permitted.

• Serum creatinine ≤ 2.0 mg/dL within 72 hours of initiating the Induction Cycle
• Total bilirubin ≤ 2.1 mg/dL within within 72 hours of initiating the Induction Cycle (EXCEPTION: If elevation is not due to liver dysfunction, and is due primarily to elevated unconjugated hyperbilirubinemia secondary to Gilbert's syndrome, or hemolysis of non-hepatic origin)
• Serum glutamic oxaloacetic transaminase (SGOT) [aspartate aminotransferase (AST) ] ≤ 3.0 X upper limit of normal (ULN) within 72 hours of initiating the Induction Cycle

• Baseline prothrombin time (PT)/international normalized ratio (INR) ratio < 3 X ULN within 7 days of initiating the Induction Cycle (for subjects with correctable coagulation abnormalities, coagulation factor support per institutional standard of care for AML is allowed)
• Partial thromboplastin time (PTT) < 3 X ULN within 7 days of initiating the Induction Cycle (for subjects with correctable coagulation abnormalities, coagulation factor support per institutional standard of care for AML is allowed)
• Negative pregnancy test within 14 days prior to study treatment (for Women of reproductive potential only)
• Women of child-bearing potential and men must agree (in ICF) to use adequate contraception (eg, hormonal or barrier methods of birth control; abstinence; sterilized partner) for the duration of study participation
• Ability to understand and the willingness to sign the written informed consent document
