Alisertib in Treating Patients With Myelofibrosis or Relapsed or Refractory Acute Megakaryoblastic Leukemia

Not Applicable

Conditions: Acute Megakaryoblastic Leukemia
Myelofibrosis
Primary Myelofibrosis

Interventions: Drug: Alisertib
Other: Laboratory Biomarker Analysis
Other: Pharmacological Study

Registration Number: NCT02530619

Lead Sponsor: Northwestern University

Brief Summary: The purpose of this study is to evaluate the safety of alisertib and its effect, bad and/or good, on acute megakaryoblastic leukemia (AMKL) or myelofibrosis (MF). The study drug, alisertib, is an investigational drug. An investigational drug is one that has not been approved by the U.S. Food and Drug Administration (FDA). Alisertib has shown evidence in the lab that it may have an effect on a type of cell that produces platelets. This cell is called a megakaryocyte and it is known to be defective (doesn't work well) in both AMKL and MF.

Detailed Description: PRIMARY OBJECTIVES:

I. Determine the safety profile of alisertib in patients with acute megakaryoblastic leukemia (AMKL) and in patients with myelofibrosis (MF).

SECONDARY OBJECTIVES:

I. Determine preliminary efficacy of alisertib in both populations.

TERCIARY OBJECTIVES:

I. Describe pharmacodynamics (PD) effects of alisertib in peripheral blood and/or bone marrow samples.

II. Evaluate the relationship between biomarker expression levels and response to alisertib.

III. Evaluate reduction in splenomegaly by palpation (MF arm only). IV. Evaluate improvement in MF symptoms (MF arm only), as assessed by the Myeloproliferative Neoplasm Symptom Assessment form (MPN-SAF).

V. Assess change in bone marrow fibrosis in patients in the MF arm.

OUTLINE:

Patients receive alisertib orally (PO) twice daily (BID) on days 1-7. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at approximately 30 days and 6 months.

Safety Profile of Alisertib Per NCI's Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0.	From time of treatment to 6 months post discontinuation (range of cycles attempted 1 to 29, median 7.5 cycles, 1 Cycle = 21 days)	Adverse events will be defined as those included in CTCAE v 4.0. The AEs that were determined to be at least possibly related to study drug and graded 3, 4, 5 are included here. Grade 1 (mild): the event causes discomfort without disruption of normal daily activities. Grade 2 (moderate): the event causes discomfort that affects normal daily activities. Grade 3 (severe): the event makes the patient unable to perform normal daily activities or significantly affects his/her clinical status. Grade 4 (Life-threatening): the patient was at risk of death at the time of the event. Grade 5 (fatal): the event caused death. All patients who received at least 1 dose of alisertib were considered evaluable for this endpoint.

Secondary Outcome Measures

Name	Time	Method
Response to Treatment	Baseline to up to 6 months after the last dose of treatment	Serial blood and/or bone marrow samples will be collected at specific timepoints for each disease to determine response to alisertib treatment.
