  • Response [ Time Frame: 6 months ]
    Assessed by cytogenetics/fluorescence in situ hybridization (FISH) and flow cytometry of blood and bone marrow samples. The response criteria defined by Cheson et al. will be used in this study. These criteria are: morphologic leukemia-free state; morphologic complete remission (CR); cytogenetic CR (CRc); molecular CR (CRm); morphologic CR with incomplete blood count recovery (CRi); partial remission (PR); treatment failure; recurrence (progressive disease).
  • Incidence of Greater Than or Equal to Grade 3 Toxicity [ Time Frame: Up to day +100 after end of therapy or until the patient received an alternative treatment for leukemia, whatever happens earlier ]
    Toxicities will be graded using the National Cancer Institute (NCI) Common Toxicity Criteria version 3.0.
  • Maximum Tolerated Dose [ Time Frame: 6 months ]
    A bayesian approach to estimate the MTD of bendamustine associated with a CR rate of at least 40% and with <30% grade 3-4 non-haematological toxicity was used (Wathen et al, 2008).The MTD of bendamustine in combination with idarubicin was determined after two cases of grade 3 toxicity were noted in the three patients entered at the 75 mg/m2 dose. The DLTs were congestive heart failure and mucositis in one patient each. Patients subsequent to this were treated at the 60 mg/m2 bendamustine dose.
  • Median Survival [ Time Frame: 5 years ]
    In a five year following, the median survival was obtained.
  • Maximum tolerated dose of bendamustine hydrochloride (for the entire study) [ Time Frame: 16 months ]
    Cohorts of 3 patients will be assessed for both toxicity (<30% grade 3-4 non hematologic) and response (>40% CR). If parameters are met Bendamustine dose will be escalated to the next higher dose. There are 4 dosing stages, and more than 1 cohort of 3 patients may be needed to fully determine outcome prior to escalation. We estimate 2-3 months per cohort, therefore conservative estimate is that in 16 months of this 24 month study, dose escalation element of the study will be complete.
  • Complete response rate (on a per patient basis) [ Time Frame: 8 weeks ]
    For each patient treated, CR will be measured during the first and second cycles. IF the patient fails to achieve CR in the first cycle, they may continue to receive a 2nd cycle. If a patient fails to achieve CR by the end of the 2nd cycle, the patient will move on to alternatives to this therapy. Therefore the CR rate per patient will be completely determined by the 8 weeks, the time required for 2 cycles to be administered and followed. For the entire study, the CR rate will be determined only after the final patient has been treated. Therefore study CR rate time frame is 27 months.
  • Toxicity [ Time Frame: 4 weeks per patient ]
    For each patient treated, toxicity will be measured during each of the three possible cycles. Initial dose limiting toxicity will be determined within 4 weeks of each bendamustine dose cycle. The acute toxicity in each patient therefore will be expected to be completely assessed 28 days after their final bendamustine dose cycle, in their 1st, 2nd, or 3rd cycle, depending. For the entire study, the toxicity rate will be determined only after the final patient has been treated. Therefore the study toxicity assessment time frame is 27 months.

In a five year following, the disease free survival was obtained.
  • Disease-free survival [ Time Frame: 36 months following final patient treatment ]

Bendamustine and Idarubicin in Treating Older Patients With Previously Untreated AML or MDS
Safety and Clinical Activity of Treanda® (Bendamustine HCL) and Idarubicin in Combination Therapy for Patients Age >= 50 With Previously Untreated Acute Myeloid Leukemia and High Risk Myelodysplastic Syndrome
This phase I/II trial is studying the side effects and best dose of bendamustine hydrochloride when given together with idarubicin in treating older patients with previously untreated acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Drugs used in chemotherapy, such as bendamustine hydrochloride or idarubicin, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more cancer cells


I. The maximum tolerated dose (MTD) that is associated with a complete remission (CR) rate of at least 40%, and a rate of grade 3-4 extramedullary toxicity < 30% in patients aged 50 or older with previously untreated AML or high-risk MDS.


I. The disease-free survival (DFS), and overall survival (OS) after therapy at each level of the dosing strategy.

OUTLINE: This is a phase I, dose-escalation study of bendamustine hydrochloride followed by a phase II study.

Patients receive bendamustine hydrochloride intravenously (IV) on days 1-5 and idarubicin IV on days 1 and 2. Treatment repeats every 28 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years and then annually thereafter for 3 years.
