Details and patient eligibility

About

This phase II trial is studying how well AKT inhibitor MK-2206 works in treating patients with relapsed or refractory acute myeloid leukemia (AML). AKT inhibitor MK-2206 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Full description

PRIMARY OBJECTIVES:

I. Determine the proportion of patients achieving Morphologic Complete Response (CR), Morphologic CR with incomplete count recovery (CRp) or Partial Response (PR) as best response within 3 cycles of therapy with MK-2206.

SECONDARY OBJECTIVES:

I. Describe the disease-free survival of patients that achieve CR/CRp.

II. Determine the toxicity profile of single-agent MK-2206 in this patient population.

III. To determine the biologic effects of MK-2206 on leukemia cells.

OUTLINE:

Patients receive AKT inhibitor MK-2206 orally (PO) once weekly. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.

Inclusion criteria

Patients must have histologically or cytologically confirmed AML other than acute promyelocytic leukemia (2008 World Health Organization (WHO) classification)
Patients must have persistent or relapsing disease requiring 2nd salvage therapy (e.g. treatment for second or higher relapse or for primary refractory disease after failure of two prior treatment regimens); duration of prior complete remission < 12 months if not refractory disease; patients with prior autologous and allogeneic hematopoietic stem cell transplantation are eligible if patients are off immunosuppression for >1 month and have no evidence of active graft versus host disease (GVHD) except grade 1 skin GVHD
Patients age >= 60 years with less than two prior treatment regimens not candidates for or have refused standard chemotherapy, excluding subjects with acute promyelocytic leukemia (APL) or with favorable cytogenetic abnormalities [inv16, t(8;21)]
Patient at the time of enrollment should not be a candidate for allogeneic stem cell transplantation
The Eastern Cooperative Oncology Group (ECOG) performance status =< 2
Serum creatinine or calculated creatinine clearance =< 1.5 * upper limit of normal (ULN) OR >= 60 mL/min for patients with creatinine levels > 1.5 * institutional ULN
Serum total bilirubin =< 2 * ULN OR direct bilirubin =< ULN for patients with total bilirubin levels > 2 * ULN, unless elevation is thought to be due to hepatic infiltration by AML, Gilbert's syndrome, or hemolysis
asparate aminotransferase (AST/SGOT) and alanine aminotransferase (ALT /SGPT) =< 2.5 * ULN or =< 5 * ULN unless considered to be secondary to leukemic involvement
Fasting serum glucose =< 150 mg/dl
HBA1c =< 9%
Female patient of childbearing potential must have a negative serum or urine pregnancy test beta- Human chorionic gonadotropin (hCG) within 72 hours prior to receiving the first dose of study medication; the effects of MK-2206 on the developing human fetus at the recommended therapeutic dose are unknown; for this reason women of childbearing potential and men must use two forms of 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, the patient should inform the treatment physician immediately
Patient, or the patient"s legal representative, has voluntarily agreed to participate by giving written informed consent
Patient is able to swallow tablets and has no surgical or anatomical condition that will preclude the patient from swallowing and absorbing oral medications on an ongoing basis

Exclusion criteria

Patients may not be receiving any other investigational agents
Major surgery, other than diagnostic surgery, within 4 weeks prior to Day 1, without complete recovery
Active uncontrolled infection
Systemic chemotherapy (with the exception of hydroxyurea) within 14 days (or within 5 half-lives for an investigational agent) prior to first dose of study drug, unless there is evidence of rapidly progressive disease; persistent chronic clinically significant toxicities from prior chemotherapy must not be > grade 1
Patients with central nervous system (CNS) involvement
Patient has known hypersensitivity to the components of study drug or its analogs
Uncontrolled congestive heart failure, unstable angina pectoris
Uncontrolled cardiac arrhythmia
History or current evidence of a myocardial infarction during the last 6 months
corrected Q-T interval (QTc) prolongation > 450 msec (Bazett's Formula)

Patient with poorly controlled diabetes defined as HBA1C > 9%
Patient is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the study
