Acute Myeloid Leukemia Clinical Trial
Veliparib and Temozolomide in Treating Patients With Acute Leukemia
This phase I clinical trial is studies the side effects and best dose of giving veliparib together with temozolomide in treating patients with acute leukemia. Veliparib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving veliparib together with temozolomide may kill more cancer cells.
I. To define the maximum-tolerated dose (MTD) and recommended phase II dose of ABT-888 (veliparib) administered in combination with temozolomide in patients with acute leukemias.
II. To evaluate the feasibility, safety, and toxicity of administering ABT-888 in combination with temozolomide in patients with acute leukemias.
I. To document response in acute leukemias. II. To observe the pharmacokinetics of both ABT-888 and temozolomide when administered alone and in combination.
III. To study the pharmacodynamics to determine the levels of poly(ADP-ribose) (PAR) before and after administration of ABT-888 and temozolomide in patient leukemia blasts, to analyze methyl-guanine methyl-transferase (MGMT) protein levels in primary leukemia blasts, and to quantify the induction of gamma-H2A histone family, member X (y-H2AX) and RAD51 recombinase (RAD51) foci in patient leukemia blasts after treatment.
OUTLINE: This is a dose-escalation study of veliparib.
Patients receive veliparib orally (PO) once daily (QD) on day 1 and twice daily on days 4-12 and temozolomide PO QD on days 3-9 of course 1.
Beginning at least 30 days after the start of treatment, patients receive veliparib PO twice daily (BID) on days 1-8 and temozolomide PO QD on days 1-5. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Patients achieving complete remission receive 5 more courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 30 days.
Histologically or cytologically confirmed diagnosis of one of the following:
Relapsed or refractory acute myeloid leukemia (AML); patients with acute promyelocytic leukemia t(15;17) must have failed tretinoin (ATRA), arsenic, and gemtuzumab ozogamycin to be eligible (patients should be refractory to all three agents-absence of durable hematologic response or relapse with complete remission [CR] duration of less than 6 months)
Relapsed or refractory pre-B- or T-cell acute lymphoblastic leukemia (ALL); patients with Philadelphia chromosome-positive (Ph+) ALL [t(9;22)] will be eligible provided that they have failed (intolerance/resistance) at least 2 different tyrosine kinase inhibitors (TKIs) or have a mutation associated with resistance to TKIs (T315I)
Chronic myelogenous leukemia (CML) in accelerated or blastic phase; patients failed (resistance/intolerance) at least 2 different TKIs or have a mutation associated with resistance to TKIs (T315I)
Chronic myelomonocytic leukemia-2 (CMML-2) defined as having > 10% blasts (including promonocytes) in the bone marrow or > 5-19% blasts (including promonocytes) in the peripheral blood
AML arising in the setting of antecedent myelodysplasia (MDS) or myeloproliferative disorder (MPD)
Untreated AML in adults 60 years of age and older who are not candidates for induction chemotherapy due to poor-risk features including adverse cytogenetics or molecular markers (fms-related tyrosine kinase 3 [FLT3] internal tandem duplication [ ITD]+), or are unwilling to receive intensive induction chemotherapy; adverse cytogenetics: complex karyotype (>= 3 chromosomal abnormalities), 5q-, 7q-, 9q-, 20q-, abn12p, +21, +8, t(6;9), t(6;11), t(11;19), -7, -5, inv3/t(3;3), abn11q23, abn17p, abn21q
Untreated ALL in adults 60 years of age and older who are not candidates for induction chemotherapy due to poor-risk features including adverse cytogenetics [t(4;11); t(1;19), hypodyploidy] or are unwilling to receive intensive induction chemotherapy; patients with Ph+ ALL [t(9;22)] will be eligible provided that they have failed (intolerance/resistance) at least 2 different TKIs or have a mutation associated with resistance to TKIs (T315I)
Only patients who have received or are ineligible for established curative regimens, including stem cell transplantation when applicable, can be enrolled on this study
Patients may have received any number of prior chemotherapy regimens, which may include allogeneic or autologous transplantation, provided that performance status and organ function are maintained
Previous cytotoxic chemotherapy should have been completed at least 3 weeks and radiotherapy at least 2 weeks prior to treatment on the study (6 weeks if the last regimen included carmustine [BCNU] or mitomycin C) and all adverse events (excluding alopecia, acne, rash) due to agents administered more than 3 weeks earlier should recover to =< grade 1; patients with hematologic malignancies are expected to have hematologic abnormalities at study entry; these abnormalities which are thought to be primarily related to the underlying leukemia, are not considered to be toxicities (AE) and do not need to resolve to =< grade 1
Patients should stop taking all biologic agents including hematopoietic growth factors, imatinib or similar TKIs, at least 1 week prior to treatment on the study and all adverse events (excluding alopecia, acne, rash) due to agents administered more than 1 week earlier should recover to =< grade 1; since only patients with advanced Ph+ ALL and CML in accelerated/blast phase are eligible for this study, this short period off TKIs was selected to avoid rapid leukemia progression; if using hydroxyurea, corticosteroids, or leukopheresis for blast count control, patients must be off >= 24 hrs before starting treatment on the study
Patients who have undergone autologous stem cell transplantation (ASCT) are eligible provided that they are >= 4 weeks from stem cell infusion and meet other eligibility criteria
Patients who have undergone allogeneic SCT (alloSCT) are eligible if they are >= 60 days post stem cell infusion, have no evidence of graft vs. host disease, and are >= 2 weeks off all immunosuppressive therapy
Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
Patients have to be able to swallow pills
Total or direct bilirubin < 2 mg/dl
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) < 5 X institutional upper limit of normal
Creatinine < 2 mg/dl
Female patients of childbearing potential must have a negative pregnancy test
Female patients of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 30 days afterward; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
Ability to understand and the willingness to sign a written informed consent document
Patients may not be receiving any other investigational agents, or concurrent chemotherapy, radiation therapy, or immunotherapy
Any previous treatment with temozolomide
Patients with active central nervous system leukemia are excluded from this clinical trial because they may develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events; patients with a history of central nervous system (CNS) leukemia but no active disease at the time of enrollment are eligible
Hyperleukocytosis with > 30,000 blasts/ul; (if using hydroxyurea, corticosteroids, or leukopheresis for blast count control, patients must be off >= 24 hrs before starting treatment on the study); once patient starts treatment on the study the hydroxyurea use should be avoided, however, for patients with rapidly proliferating disease use of hydroxyurea is allowed on treatment days 1 through 12 if it becomes necessary to control a rising white blood cell (WBC) or leukostasis; the WBC need not reach 30,000/ul to start hydroxyurea during protocol days 1-12; the decision to start hydroxyurea during this time is at the discretion of the treating physician
History of allergic reactions attributed to compounds of similar chemical or biologic composition to ABT-888 or temozolomide used in this study
Active, uncontrolled infection; patients with infection under active treatment and controlled with antibiotics are eligible
Uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Pregnant women are excluded from this study; breastfeeding should be discontinued if the mother is treated with ABT-888
Known human immunodeficiency virus (HIV) infected patients (HIV testing will not be performed as a part of screening) on combination antiretroviral therapy, exclusive of zidovudine or starvudine, or HIV infected patients not on or willing to suspend antiretroviral therapy will be eligible provided that their cluster of differentiation (CD)4 cell count is greater than 250/mm3; HIV infected patients with CD4 count equal or less than 250/mm3 will be excluded
