The goal of this clinical research study is to learn if the combination of Gleevec (imatinib mesylate) and low doses of Cytarabine (ara-C) may help to control leukemia while causing fewer side effects than standard high dose chemotherapy.

Primary Outcome Measures:
  • Efficacy of a combination of imatinib and low dose ara-C in elderly or high-risk patients with AML and MDS, as measured by the rate of early mortality or progression. [ Time Frame: April 2007 ]

Secondary Outcome Measures:
  • Rate of overall response, including CRp and PR. [ Time Frame: April 2007 ]
  • To determine the safety profile of this combination. [ Time Frame: April 2007 ]
  • To determine the impact on long-term survival of this therapy. [ Time Frame: April 2007 ]
  • To determine the duration of responses obtained with this therapy. [ Time Frame: April 2007 ]
  • To determine the impact of this therapy in cognitive function. [ Time Frame: April 2007 ]
  • To determine the effect of this approach in quality of life of this patient population. [ Time Frame: April 2007 ]
  • To determine the overall costs (health economic analysis) associated with this combination therapy. [ Time Frame: April 2007 ]

Detailed Description:

Imatinib mesylate is a drug that blocks a certain protein. This protein is thought to be important in the growth of leukemia cells. Ara-C is a chemotherapy drug that has been used for many years to treat AML and MDS.

Imatinib mesylate (Gleevec) is a protein-tyrosine kinase inhibitor that inhibits the Bcr-Abl tyrosine kinase, as well as the receptor tyrosine kinases for platelet- derived growth factor (PDGF) and stem cell factor (SCF), c-Kit, and inhibits PDGF- and SCF-mediated cellular events. c-Kit is expressed in over 90% of patients with AML.

The treatment of AML for patients age 65 or older with AML or high-risk MDS (age ³ 60 if high-risk cytogenetics) have a poor prognosis with induction chemotherapy. Response rate is no more than 45% with an induction mortality of at least 25%, and 1-year survival no better than 20%. Indeed, most patients in these age groups are not even offered therapy and are managed with supportive care only. Thus, new therapies that are better tolerated are needed.

Imatinib alone can induce response in nearly 20% of patients, and there is synergy with low concentrations of ara-C. In this study we plan to investigate the combination of imatinib and low-dose ara-C.


Ages Eligible for Study:   60 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients who are not candidates for intensive chemotherapy with any of the following diagnosis: 1. AML or MDS (with >/=5% blasts) age >/= 65 years old (or age >/= 60 if high-risk cytogenetics), or 2. AML or MDS (RAEB or RAEBT) of any cytogenetic group age 60 or older with minimally treated disease who have relapsed disease or are refractory to therapy and not likely to require cytoreductive therapy within one month, and, or 3. CMML.
  • Patients with WHO performance status of 0 to 2
  • Patients must have recovered from prior cytotoxic chemotherapy; treatment with hydrea is allowed up to 24 hours prior to day 1 of study drug administration
  • Written informed consent obtained according to local guidelines
  • Patients must have a serum creatinine of </= 1.5 x ULN, SGPT </= 3 x ULN and total bilirubin </= 2.0 x ULN.
  • Patients with >/= 20% blasts positive for c-kit (CD117) (except for CMML)
  • Postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential.
