简要总结
This phase I trial studies the side effects and best dose of entinostat when given together with clofarabine in treating patients with newly diagnosed, relapsed, or refractory poor-risk acute lymphoblastic leukemia or bilineage/biphenotypic leukemia. Entinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as clofarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving entinostat with clofarabine may kill more cancer cells.
详细描述
PRIMARY OBJECTIVES:
I. To determine the feasibility, tolerability, toxicities, and maximum tolerated dose (MTD) of entinostat plus clofarabine for: adult patients age 40 and over with newly diagnosed, poor-risk Philadelphia chromosome negative (Ph-) acute lymphoblastic leukemia (ALL) or bilineage/biphenotypic leukemia (ABL) prior to traditional cyclical multi-agent chemotherapy, and adults age 21 and over with relapsed or refractory ALL/ABL.
II. To determine if entinostat plus clofarabine can induce clinical responses in adults with newly diagnosed, poor-risk ALL/ABL and in adults with relapsed/refractory ALL/ABL.
SECONDARY OBJECTIVES:
I. To determine pharmacokinetics (PK) of entinostat alone and in combination with clofarabine.

排除标准

- •Concomitant chemotherapy, radiation therapy, or immunotherapy
- •Hyperleukocytosis with >= 150,000 blasts/uL (if using hydroxyurea, steroids, maintenance doses of 6-mercaptopurine and/or methotrexate, arsenic, interferon or leukapheresis for blast count control, patient must be off those agents for 24 hours prior to beginning entinostat plus clofarabine)
- •Active disseminated intravascular coagulation (DIC)
- •Active central nervous system (CNS) leukemia; patients with known previous CNS leukemia may continue to receive intrathecal therapy with cytarabine (ara-C), methotrexate, and/or thiotepa plus steroids as prophylaxis against reactivation of active CNS disease
- •Use of investigational cytotoxic agents within 30 days or any anticancer therapy within 14 days before study entry, except for hydroxyurea and steroids, both of which must be discontinued at least 24 hours before study entry; the patient must have recovered from all acute toxicities from any previous therapy; the patient must have recovered from all acute toxicities from any previous therapy
- •Patients must have discontinued all growth factors at least 3 days before study

研究组 & 干预措施
Treatment (entinostat and clofarabine)
Patients receive entinostat PO on days 1 and 8 and clofarabine IV over 2 hours on days 3-7. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity (only for patients >= 60 years of age with newly diagnosed ALL or ABL who are unable or unwilling to tolerate standard multi-agent chemotherapy and patients with relapsed or refractory ALL or ABL).
Patients 40-59 years of age with newly diagnosed ALL receive standard multi-agent induction chemotherapy beginning on day 11. Patients >= 21 years of age in their first relapse with sensitive disease begin initiation of allogeneic transplant after one course of entinostat and clofarabine.
