About

This phase II trial studies how well ibrutinib works in treating patients with B-cell acute lymphoblastic leukemia that has come back after treatment or has not responded to other treatment. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Full description

PRIMARY OBJECTIVES:

I. To evaluate the efficacy of ibrutinib in patients with relapsed or refractory B-cell acute lymphoblastic leukemia (B-ALL) as measured by objective response rate (ORR).

SECONDARY OBJECTIVES:

I. To evaluate the global safety profile of ibrutinib in patients with relapsed or refractory B-ALL.

II. To assess response duration. III. To assess Bruton's tyrosine kinase (BTK) target inhibition, biomarkers, and gene expression profiles in B-ALL patient samples before and during treatment with ibrutinib.

OUTLINE:

Patients receive ibrutinib orally (PO) once daily (QD) on days 1-28. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days.

Inclusion criteria

Relapsed or refractory B-ALL due to receive salvage 1, 2, 3, 4, 5, or 6; half of the patients, i.e. 5 out of the first 10 patients, and 5 out of 10 patients thereafter, need to be in earlier line of salvage therapy, defined as 1st, 2nd, or 3rd line of salvage therapy; Philadelphia chromosome-positive (Ph+) B-ALL patients must have failed treatment with at least 1 second generation tyrosine kinase inhibitor; patients in salvage 1 with late relapse should be deemed poor candidates for reinduction with initial therapy; patients with ALL of T cell origin (T-ALL) can not be treated
Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
Total bilirubin =< 1.5 × upper limit of normal (ULN) (unless Gilbert's syndrome or disease infiltration of the liver is present)
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.0 × institutional ULN
Creatinine clearance (Cockcroft-Gault) greater than or equal to 30 mL/min or estimated (est) glomerular filtration rate (GFR) greater than or equal to 30 mL/min/1.73 m^2
For any surgery or invasive procedure requiring sutures or staples for closure, ibrutinib should be held at least 7 days prior to the intervention and should be held at least 7 days after the procedure, and restarted at the discretion of the investigator when the surgical site is reasonably healed without serosanguineous drainage or the need for drainage tubes
Bone marrow involvement with >= 5% lymphoblasts, peripheral blast count less than 5,000 per uL
Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; female patients need a negative serum or urine pregnancy test within 14 days of study start (applies only if patient is of childbearing potential); non-childbearing is defined as >= 1 year postmenopausal or surgically sterilized; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 4 months after completion of ibrutinib administration
Ability to understand and the willingness to sign a written informed consent document

Exclusion criteria

Patients who receive other chemotherapy; patients must have been off previous therapy for >= 2 weeks and must have recovered from clinically significant toxicity (to grade 1 or less) of all previous therapy prior to enrollment (consent signing) with the following exceptions: steroids, hydroxyurea, oral mercaptopurine, methotrexate, vincristine (including prophylactic intrathecal medication), thioguanine, and tyrosine kinase inhibitors are permitted within 2 weeks of randomization as maintenance or to reduce the peripheral blood blast counts; during ibrutinib therapy, only steroids and hydroxyurea are permitted to reduce peripheral blood blast counts; patients who have had chemotherapy or radiotherapy within 2 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 2 weeks earlier
Patients who are receiving any other investigational agents
Active central nervous system (CNS) leukemia, as defined by unequivocal morphologic evidence of lymphoblasts in the cerebrospinal fluid (CSF), use of CNS-directed local treatment for active disease within the prior 28 days, symptomatic CNS leukemia (i.e., cranial nerve palsies or other significant neurologic dysfunction) within 28 days; prophylactic intrathecal medication is not a reason for exclusion; patients with known brain metastases should be excluded from this clinical trial
History of allergic reactions attributed to compounds of similar chemical or biologic composition to ibrutinib
Concomitant use of drugs that strongly inhibit cytochrome P450, family 3, subfamily A, polypeptide 4/5 (CYP3A4/5)
Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection or an infection requiring systemic antibiotics, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Pregnant and breastfeeding women are excluded from this study; breastfeeding should be discontinued if the mother is treated with ibrutinib
Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are eligible, unless the patient's cluster of differentiation (CD)4 count is below the institutional lower limit of normal, or the patient is taking prohibited CYP3A4/5 strong inhibitors or inducers
