Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Clofarabine has demonstrated anti-cancer activity through inhibition of DNA synthesis and repair, induction of apoptosis, and possibly through other mechanisms. Numerous responses have been observed after treatment with clofarabine in heavily pre-treated relapsed/refractory patients with ALL, AML and high risk MDS.
In the present proposal, the investigators will study the clinical and laboratory effects of 2 different dosages of clofarabine in patients who have failed the hypomethylating agent, 5-azacytidine. This study will recruit patients who have received at least six cycles of 5-azacytidine without response or whose disease has progressed or relapsed while on 5-azacytidine. The first cohort of patients will receive clofarabine 10 mg/m2/day for five days and the second cohort of patients 5 mg/m2/day for five days, both every four to six weeks. The investigators will determine the frequency of response to the two dosages of nucleoside analog in this group of patients. Measurement of responses will include improvement in the peripheral blood count, reduction in the blood and platelet transfusion need and eradication of cytogenetically abnormal clones. Successful completion of this study will define the position of clofarabine in MDS in the era of epigenetic targeting.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study will recruit patients who have received at least six cycles of 5-azacytidine without response or whose disease has progressed or relapsed while on 5-azacytidine. The first cohort of patients will receive clofarabine 10 mg/m2/day for five days and the second cohort of patients 5 mg/m2/day for five days, both every four to six weeks. The investigators will determine the frequency of response to the two dosages of nucleoside analog in this group of patients. Measurement of responses will include improvement in the peripheral blood count, reduction in the blood and platelet transfusion need and eradication of cytogenetically abnormal clones.
* Primary Objectives
1. To determine the frequency and duration of peripheral blood responses to IV clofarabine in MDS patients who have failed 5-azacytidine
2. To determine the frequency and duration of bone marrow responses to IV clofarabine, including CR + PR
* Secondary Objectives
To determine whether clofarabine exhibits a DNA hypomethylating property

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
10 mg/m2 group
Patients were treated with Clofarabine 10 mg/m2 daily x 5 days per cycle. Cycles were intended on being every 28 days but this was flexible due to the bone marrow neding to recover from each cycle before strting the next one. Neulasta was given on day 5 of each cycle. Patients were treated until disease progression, or intolerable toxicities.
Clofarabine
10 mg/m2 x 5 days per 4 to 6 week cycles
5 mg/m2 group
Patients were treated with Clofarabine 5 mg/m2 daily x 5 days per cycle. Cycles were intended on being every 28 days but this was flexible due to the bone marrow neding to recover from each cycle before strting the next one. Neulasta was given on day 5 of each cycle. Patients were treated until disease progression, or intolerable toxicities.
Clofarabine

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* ECOG Performance status of 0 - 2
* Recombinant erythropoietin is allowed, if the patients are already receiving erythropoietin. G-CSF can be given during the neutropenic stage following therapy since this would not affect evaluation of response because the response will be made based on CBC and bone marrow changes upon recovery from clofarabine.
* Patients must have been at least four weeks after the last course of 5-azacytidine
* Age over 18 years
* Have adequate renal and hepatic functions as indicated by the following laboratory values:
* Serum creatinine 1.0 mg/dL; if serum creatinine 1.0 mg/dL, then the estimated glomerular filtration rate (GFR) must be 60 mL/min/1.73 m2 as calculated by the Modification of Diet in Renal Disease equation where Predicted GFR (ml/min/1.73 m2) = 186 x (Serum Creatinine)-1.154 x (age in years)-0.023 x (0.742 if patient is female) x (1.212 if patient is black)
* Serum bilirubin ≤1.5 mg/dL × upper limit of normal (ULN)
* Aspartate transaminase (AST)/alanine transaminase (ALT) 2.5 × ULN
* Alkaline phosphatase 2.5 × ULN
* Capable of understanding the investigational nature, potential risks and benefits of the study, and able to provide signed informed consent.
* Female patients of childbearing potential must have a negative serum pregnancy test within 2 weeks prior to enrollment.
* Male and female patients must use an effective contraceptive method during the study and for a minimum of 6 months after study treatment.
Exclusion Criteria
* Prior clofarabine therapy
* Life expectancy of less than 3 months due to other intercurrent illness.
* Current concomitant chemotherapy, radiation therapy, or immunotherapy other than as specified in the protocol.
* Use of investigational agents within 30 days or any anticancer therapy within 4 weeks before study entry with the exception of hydroxyurea. The patient must have recovered from all acute toxicities from any previous therapy.
* Have any other severe concurrent disease, or have a history of serious organ dysfunction or disease involving the heart, kidney, liver, or other organ system that may place the patient at undue risk to undergo treatment.
* Patients with a systemic fungal, bacterial, viral, or other infection not controlled (defined as exhibiting ongoing signs/symptoms related to the infection and without improvement, despite appropriate antibiotics or other treatment).
* Any significant concurrent disease, illness, or psychiatric disorder that would compromise patient safety or compliance, interfere with consent, study participation, follow up, or interpretation of study results.
