The Maximum Tolerated Dose (MTD) of Oral Clofarabine in Adult Patients With Relapsed CD20+ Non-Hodgkin Lymphoma(NHL) 14 days for up to 8 cycles (1 cycle equals 14 days on drug, 14 days off drug) for a total of up to 224 days [clinicaltrials_resource:784f522f535fd1e2d8d60625a9c7dce4]

Initially, 3 patients will be enrolled into a dose level during the dose-escalation portion: If no patient experiences dose-limiting toxicities during the first 4 weeks, then 3 patients will be enrolled into the next dose level. If one of the three patients develops dose-limiting toxicities, then 3 additional patients will be enrolled in that cohort. If none of the additional 3 patients experiences dose-limiting toxicities, then further dose-escalation occurs. If one additional patient experiences dose-limiting toxicities, then the maximum tolerated dose is exceeded.
