Clofarabine plus cytarabine in patients with previously untreated acute myeloid leukemia and high-risk myelodysplastic syndrome Clinical Trials References presented on Clinical Trials Search isn't meant to be a substitute for proven healthcare advice, trips or professional assistance using a genuine physician. We are not docs. Always confer with your physician about Clofarabine plus cytarabine in patients with previously untreated acute myeloid leukemia and high-risk myelodysplastic syndrome conditions. Clinical Trials Search.org is a site devoted to listing clinical research studies in human subjects. Clofarabine plus cytarabine in patients with previously untreated acute myeloid leukemia and high-risk myelodysplastic syndrome Clinical research trials and Clofarabine plus cytarabine in patients with previously untreated acute myeloid leukemia and high-risk myelodysplastic syndrome healthcare trials happen in hundreds of localities throughout the United States of America. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials usually evaluate the potency of new drugs. The propose of the studies / projects is to answer particular human health questions. Clinical trials are a popular way for mDs, government agencies, and private sector companies to detect cures for all sorts of conditions, such as Clofarabine plus cytarabine in patients with previously untreated acute myeloid leukemia and high-risk myelodysplastic syndrome. Clofarabine plus cytarabine in patients with previously untreated acute myeloid leukemia and high-risk myelodysplastic syndrome Clinical Trials and other clinical trials allow volunteers to acquire healthcare treatment choices before they are available to the general public. Some times the subjects recieve professional assistance for free, and every now and again they are compensated for their time. Sometimes there is a cost for a Clofarabine plus cytarabine in patients with previously untreated acute myeloid leukemia and high-risk myelodysplastic syndrome clinical trial. Subjects frequently obtain the most expert healthcare possible for their Clofarabine plus cytarabine in patients with previously untreated acute myeloid leukemia and high-risk myelodysplastic syndrome condition. Risks are a reality, nevertheless, and can include more or frequent doctor trips, medical risks (possibly life-threatening), and/or the treatment being uneffective. Trials are federally governed with stern guidelines to protect clinical trials patients.

Clofarabine plus cytarabine in patients with previously untreated acute myeloid leukemia and high-risk myelodysplastic syndrome
For Condition: Leukemia, Myeloid,Myelodysplastic Syndromes
Status: Suspended
Sponsor(s): M.D. Anderson Cancer Center , ILEX Products
Synopsis: The goal of this clinical research study is to learn if clofarabine, when given in combination with ara-C (cytarabine), can help to improve the disease's response to therapy and to increase the duration of response in patients who are 50 years or older with leukemia. The safety of this combination treatment will also be studied.
Details: The treatment of acute myeloid leukemia (AML) in older patients has not improved significantly in recent years when compared with the considerable progress that has been made in younger patients. Hence, new drugs and approaches are needed in this poor-prognosis group of patients with AML. Nucleoside analogs are among the most active antileukemic agents available. Clofarabine was synthesized as a rational extension of the experience with other deoxyadenosine analogs. Clofarabine is converted to the monophosphate form by the enzyme deoxycytidine kinase which represents the major metabolite of clofarabine. Phosphorylation of clofarabine is substantially more efficient than that of other nucleosides such as fludarabine and so is intracellular retention of the triphosphate form of clofarabine. Mechanisms of action include inhibition of DNA synthesis, inhibition of DNA polymerases, and potent inhibition of ribonucleotide reductase (RNR) resulting in depletion of normal nucleotides and increased DNA uptake of the analog. Single agent clofarabine has shown activity in phase I studies in AML and ALL. As a potent inhibitor of RNR, however, clofarabine is ideal to be incorporated into biochemical modulation strategies such as have been tested and validated with fludarabine and ara-C in AML. By combining clofarabine with ara-C, inhibition of RNR by clofarabine will result in a drop of deoxynucleotides causing a decrease in the feedback inhibition of deoxcycytidine kinase which is the rate-limiting step in the synthesis of ara-CTP leading to increased retention of ara-CTP. Therefore, the activity of clofarabine and ara-C in leukemic cells would be complemented by a biochemical synergism between these agents that should result in better clinical efficacy. We have established the safety of the combination in salvage patients with acute leukemias.
Eligibility:
Study Type: Interventional,Treatment,Non-Randomized,Open Label,Historical Control,Single Group Assignment,Safety/Efficacy Study
Minimum Age/Maximum Age: 50 Years/74 Years
Genders: Both
Protocol Entry Criteria: Inclusion: 1. Previously untreated acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS) (> 10% blasts). Prior therapy with hydroxyurea, single agent chemotherapy (e.g. decitabine), hematopoietic growth factors, biological or “targeted” therapies are allowed. 2. Age > 50 years to < 74 years (diploid cytogenetics) and < 69 years (abnormal cytogenetics). 3. ECOG performance status = 2. 4. Sign a written informed consent form. 5. Adequate liver function (total bilirubin < 2mg/dL, SGPT or SGOT < x 4 ULN) and renal function (serum creatinine < 2mg/dL). 6. Male and female patients who are fertile agree to use an effective barrier method of birth control (ie, latex condom, diaphragm, cervical cap, etc) to avoid pregancy. Female patients need a negative serum or urine pregnancy test within 7 days of study enrollment (applies only if patient is of childbearing potential. Non-childbearing is defined as >= 1 year postmenopausal or surgically sterilized). 7. Patients who are considered to require immediate induction (rapidly rising WBC >/= 50,000 and/or organ involvement as per the assessment of the treating physician) can be treated without final cytogenetic results and pretreatment assessment of cardiac ejection fraction (MUGA or echocardiogram) if by history and physical examination patients have = NYHA class II disease. Exclusion: 8. AML with the following cytogenetic abnormalities: t(15;17), t(8;21), inv(16). Cytogenetic results do not need to be available if immediate induction is required (see inclusion #7). 9. Cardiac ejection fraction < 30%. Pretreatment assessment of ejection fraction is not necessary if immediate induction is required as long as by history and physical examination patients have = NYHA class II disease (see inclusion #7). 10. Active and uncontrolled infection or any other severe concurrent disease considered life-threatening, or which, in the judgement of the investigator and after discussion with the Principal Investigator, would make the patient inappropriate for entry into the study.
