简要总结
This phase I trial studies the MEK inhibitor MEK162 to see if it is safe in patients when combined with idarubicin and cytarabine. MEK inhibitor MEK162 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 cancer cells, either by killing the cells or by stopping them from dividing. Giving MEK inhibitor MEK162, cytarabine, and idarubicin may be an effective treatment for acute myeloid leukemia.
详细描述
PRIMARY OBJECTIVES:
I. Determine maximum tolerated dose (MTD) of MEK162 (MEK inhibitor MEK162) in patients with RAS-mutated acute myeloid leukemia (AML) when combined with sequential induction chemotherapy (3+4) as measured by development of grade 3-4 dose-limiting toxicities (DLT).
SECONDARY OBJECTIVES:
I. Analyze downstream inhibition of RAS signaling following therapy with single-agent MEK162 with exploratory pharmacodynamics (PD) studies.
II. Perform preliminary efficacy analysis of combination of MEK162 and induction chemotherapy (3+4) in patients with RAS-mutated AML by measuring complete remission rate, 2-year overall survival, and duration of response.

- •Any surgical procedure, excluding central venous catheter placement, bone marrow biopsy, lumbar puncture, or other minor procedures (e.g., skin biopsy) within 14 days of day 1; patients who have undergone major surgery =< 21 days prior to starting study drug or who have not recovered from side effects of such procedure are ineligible for the study
- •Pregnant or nursing (lactating) women confirmed by a positive hCG laboratory test
- •Women of child-bearing potential unless they are using highly effective methods of contraception throughout the study and for 30 days after study drug discontinuation
- •Sexually active males unless they use a condom during intercourse while taking the drug and for 30 days after stopping treatment and should not father a child in this period; a condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid
- •Unwillingness or inability to comply with the protocol
- •Known active leukemia of the central nervous system
- •Known history of Gilbert's syndrome
- •History or current evidence of retinal pigment epithelial detachment (RPED), retinal vein occlusion (RVO), or predisposing factors to RPED or RVO (e.g. uncontrolled glaucoma or ocular hypertension, uncontrolled diabetes mellitus, hyperviscosity or hypercoagulability syndromes)
- •History of retinal degenerative disease
