Biomarkers in Predicting Treatment Response to Sirolimus and Chemotherapy in Patients With High-Risk Acute Myeloid Leukemia

Brief Summary
This pilot phase II trial studies whether biomarkers (biological molecules) in bone marrow samples can predict treatment response to sirolimus and chemotherapy (mitoxantrone hydrochloride, etoposide, and cytarabine \[MEC\]) in patients with acute myeloid leukemia (AML) that is likely to come back or spread (high-risk). Sirolimus inhibits or blocks the pathway that causes cancer cells to grow. Adding sirolimus to standard chemotherapy may help improve patient response. Studying samples of bone marrow from patients treated with sirolimus in the laboratory may help doctors learn whether sirolimus reverses or turns off that pathway and whether changes in biomarker levels can predict how well patients will respond to treatment.

Outcome Measures
Primary Outcomes (2)
Biochemical Response
Defined by change in phosphorylated ribosomal protein S6 (pS6) positive blasts, measured as the % reduction in pS6 positive blasts from baseline to day 4. Biochemical response will be described by mean, median, standard deviation, range and coefficient of variation. The association between biochemical response and clinical response will be tested by Fisher's exact test.
Baseline to day 4
Clinical Response
Clinical response was assessed at Day 45 using IWG criteria: Complete Remission (CR), CR with incomplete platelet recovery (CRp), CR with incomplete hematologic recovery (CRi), Partial Remission (PR), or No Response (NR). CR requires normalized blood counts and bone marrow blasts \<5%. CRp meets CR except platelet recovery; CRi meets CR except incomplete neutrophil/platelet recovery. PR is ≥50% reduction in marrow blasts to 5-25% with partial blood count improvement. NR indicates failure to meet these criteria. Tumor response per RECIST v1.0: CR = disappearance of all target lesions; PR = ≥30% decrease in sum of longest diameters; Overall Response = CR + PR. Progression = ≥20% increase in sum of longest diameters, measurable increase in non-target lesion, or new lesions.

Study Arms (1)
Sirolimus, MEC chemotherapy
EXPERIMENTALPatients undergo collection of bone marrow samples prior to sirolimus dosing on day 4 and within 1 week and no later than day 45 of hematologic recovery. Patients receive sirolimus PO on days 2-9 (loading dose on day 1 only), and standard MEC chemotherapy comprising mitoxantrone hydrochloride IV over 15 minutes, etoposide IV over 1 hour, and cytarabine IV over 1 hour every 24 hours on day 4-8.

Eligibility Criteria
You may qualify if:
- Patients must have histologic evidence of high risk acute myeloid leukemia defined as one of the following:
- Primary refractory non-M3 AML
- Residual leukemia after a minimum of 2 prior courses of chemotherapy (Same or different)
- Evidence of leukemia recurrence after a nadir bone marrow biopsy demonstrates no evidence of residual leukemia.
- Evidence of leukemia after induction therapy which, in the opinion of the investigator, would be appropriate for reinduction with sirolimus/MEC therapy.
- Relapsed non-M3 AML
- Previously untreated non-M3 AML age \>60 with no evidence of favorable karyotype defined by presence of t(8;21)(q22;q22) \[AML1-ETO\], inv16(p13;q22), or t(16;16)(p13;q22) \[CBFβ;MYH11\] by cytogenetics, FISH, or RT-PCR
- Previously untreated secondary AML (from antecedent hematologic malignancy or following therapy with radiation or chemotherapy for another disease) with no evidence of favorable karyotype defined by presence of t(8;21)(q22;q22) \[AML1-ETO\], inv16(p13;q22), or t(16;16)(p13;q22) \[CBFβ;MYH11\] by cytogenetics, FISH, or RT-PCR
