Laboratory Biomarker Analysis

This phase II trial studies the side effects and how well fludarabine phosphate, cytarabine, filgrastim-sndz, gemtuzumab ozogamicin, and idarubicin hydrochloride work in treating patients with newly diagnosed acute myeloid leukemia or high-risk myelodysplastic syndrome. Drugs used in chemotherapy, such as fludarabine phosphate, cytarabine, and idarubicin hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Gemtuzumab ozogamicin is a monoclonal antibody, called gemtuzumab, linked to a antitumor drug, called calicheamicin. Gemtuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as CD33 receptors, and delivers calicheamicin to kill them. Colony-stimulating factors, such as filgrastim-sndz, may increase the number of immune cells found in bone marrow or peripheral blood and may help the immune system recover from the side effects of chemotherapy. Giving fludarabine phosphate, cytarabine, filgrastim-sndz, gemtuzumab ozogamicin, and idarubicin hydrochloride may kill more cancer cells.

PRIMARY OBJECTIVES:

I. Evaluate the safety of a regimen incorporating fludarabine phosphate (fludarabine), high-dose cytarabine, filgrastim-sndz, gemtuzumab ozogamicin and idarubicin hydrochloride (idarubicin) in patients with untreated inv(16) or t(8;21) acute myeloid leukemia (AML).

II. Evaluate the complete remission rates achieved in this population with this regimen.

SECONDARY OBJECTIVES:

I. Assess the proportion of patients with untreated inv(16) or t(8;21) AML who, having entered complete remission (CR) on this regimen, remain alive in CR two years from CR date.

II. Assess whether the quantitative polymerase chain reaction (Q-PCR) results can be used in detecting relapse in these patients.

OUTLINE:

REMISSION INDUCTION: Patients receive filgrastim-sndz subcutaneously (SC) once daily (QD) beginning on day -1 and continuing until blood count recovery. Patients also receive fludarabine phosphate intravenously (IV) over 30 minutes on days 1-5, cytarabine IV over 4 hours on days 1-5, gemtuzumab ozogamicin IV over 2 hours on day 1. Patients not in remission after their first induction therapy may repeat remission induction therapy.

POST-REMISSION THERAPY: Patients receive filgrastim-sndz SC on day -1, fludarabine phosphate IV over 30 minutes on days 1-3, cytarabine IV over 4 hours on days 1-3, gemtuzumab ozogamicin IV over 2 hours on day 1 of courses 1 or 2 and 5 or 6, and idarubicin hydrochloride IV over 30 minutes on days 2 and 3 of one post-remission course (post-remission courses 3 or 4) determined by the treating physician after discussion with the PI if suboptimal qPCR response (qPCR \> 0.01 after post-remission cycle 2 or 3). Treatment repeats every 4-6 weeks for up to 6 courses in the absence of disease progression or unacceptable toxicity.

FURTHER MODIFICATION OF POST-REMISSION THERAPY: Patients older than 60, with significant comorbidities, experiencing life-threatening complications, prolonged cytopenias, or not achieving complete molecular response may receive decitabine IV over 1 hour daily for 5 days after discussion with the principal investigator. Treatment repeats every 4-6 weeks for up to 12 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 months for 2 years.

Eric JOURDAN, MD,PhD

Core binding factor (CBF) acute myeloid leukemias (AML) include AMLs carrying the t(8;21) translocation as well as AMLs carrying either the inversion of chromosome 16 or translocation t(16;16). CBF-AMLs are characterized by their high sensitivity to standard chemotherapeutical agents, especially to cytarabine when administered as high-dose bolus infusions, and thus by a relative good prognosis. However, relapse rates are still comprised between 30 and 50% in these patients, even if overall survival may reach approximately 65% due to the potential salvage of late relapses.

The primary purpose of the protocol is to compare two modalities of timed-sequential induction in order to improve the results of the treatment of CBF-AML patients. This protocol also includes the biological characterization of the heterogeneity of these diseases (gene mutation and transcription profiles), as well as a centralized minimal residual disease monitoring and centralized evaluation of pharmacogenetic polymorphisms.

Core binding factor (CBF) acute myeloid leukemias (AML) include AMLs carrying the t(8;21) translocation as well as AMLs carrying either the inversion of chromosome 16 or translocation t(16;16). CBF-AMLs are characterized by their high sensitivity to standard chemotherapeutical agents, especially to cytarabine when administered as high-dose bolus infusions, and thus by a relative good prognosis. However, relapse rates are still comprised between 30 and 50% in these patients, even if overall survival may reach approximately 65% due to the potential salvage of late relapses. Initial high white blood cell count, activating mutations of cKit, Ras, and FLT3 genes, and persistence of high minimal residual disease (MRD) levels (as evidenced by AML1-ETO or CBFb-MYH11 specific RQ-PCR tools) are the main bad-prognostic factors in patients with CBF-AML.

This project includes a new single French protocol to treat patients with CBF-AML who represent approximately 15% of all AML patients. This common protocol has been elaborated by the two main French cooperative groups for adult AML (ALFA and GOELAMS). In addition to a unique specific therapeutical strategy, this protocol includes the biological characterization of the heterogeneity of these diseases (gene mutation and transcription profiles), as well as a centralized MRD monitoring and centralized evaluation of pharmacogenetic polymorphisms. This project which is well-positioned in the international competition, will use many platforms of the POLECANCER with the following objectives : 1) to improve the results of the treatment of CBF-AML patients; 2) to organize a French clinical and biological network on CBF-AML with the aim to test new targeted therapeutical agents (tyrosine kinase and/or farnesyl transferase inhibitors) in the next future.

TREATMENT DESIGN Induction course Systematic timed-sequential induction (arm A) DAUNORUBICINE (DNR): 60 mg/m2/day IV (30 min), Day 1, 2, and 3 CYTARABINE (AraC): 500 mg/m2/day Continuous infusion, Day 1 to 3 DAUNORUBICINE (DNR): 35 mg/m2/day IV (30 min), Day 8 and 9 CYTARABINE (AraC): 1 gr/m2/12 h IV (2h), Day 8, 9, and 10 Response-adapted timed-sequential induction (arm G) DAUNORUBICINE (DNR): 60 mg/m2/dayIV (30 min), Day 1, 2, and 3 CYTARABINE (AraC): 200 mg/m2/dayContinuous infusion, Day 1 to 7

Peripheral blood and bone marrow evaluation at Day 15. The following second induction course will be administered in patients with persistent marrow disease at Day 15 :

DAUNORUBICINE (DNR): 35 mg/m2/day IV (30 min), Day 16 and 17 CYTARABINE (AraC)1 gr/m2/12 h IV (2h), Day 16, 17, and 18 Persistent marrow disease at Day 15 is defined by more than 10% leukemic blasts in a non aplastic or non very hypoplastic bone marrow aspiration sample.

Salvage course In patients not reaching CR after the first induction course (either SI or TSI), a salvage course will be administered. Salvage therapy should not be initiated before Day 35 of arm A and Day 42 of arm G.

CYTARABINE (AraC) :3 gr/m2/12h IV (2h), Day 1, 3, 5, and 7 AMSACRINE : 100 mg/m2/day IV (30 min), Day 5 to 7 G-CSF lenograstim : from Day 8 until myeloid recovery (\> 500 PMN/µL)

Consolidation cycles Three monthly cycles of consolidation will be administered in all patients reaching hematological CR after induction or induction + salvage.

CYTARABINE (AraC): 3 g/m2/12h IV (2h), Day 1, 3, and 5 G-CSF lenograstim : from Day 8 until myeloid recovery (\> 500 PMN/µL)
