 | 
 
 
 | 
| E.4 | Principal exclusion criteria | 
•	Received previous treatment with clofarabine •	Current concomitant chemotherapy, radiation therapy, or immunotherapy •	Prior radiation therapy to the pelvis •	Currently participation in other investigational drug studies or having received other investigational drugs within the previous 30 days •	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. In particular: a) New York Heart Association classification stage II, III, or IV congestive heart failure; b) Coronary artery disease or arteriosclerotic cardiovascular disease (angina, myocardial infraction) within 3 months of first dose of study drug; c) Any other primary cardiac disease that, in the opinion of the investigator, increases the risk of ventricular arrhythmia. •	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 medical condition that requires chronic use of oral high-dose corticosteroids (in excess of 1 mg/kg/day) (low-dose corticosteroid for pre-medication purposes are allowed). •	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 •	Diagnosis of another malignancy, unless the patient has been disease-free for at least 5 years following the completion of curative intent therapy with the following exceptions: Patients with treated non-melanoma skin cancer, in-situ carcinoma or cervical intraepithelial neoplasia regardless of disease-free duration are eligible for this study if definitive treatment for the condition has been completed; Patients with organ-confined prostate cancer with no evidence of recurrent or progressive disease based on PSA value are eligible for this study if hormonal therapy has been initiated or a radical prostatectomy has been performed •	Had currently active gastrointestinal disease, or prior surgery that might affect the ability of the participants to absorb oral Clofarabine. •	Had prior treatment with a known nephrotoxic drug within 2 weeks of the first dose of study drug, unless the participants had a calculated GFR >30 at 2 time points no <7 days apart during the 2-week period prior to the first dose of study drug. •	Positive human immunodeficiency virus (HIV) test. •	Female patients who are pregnant/breastfeeding.
