Brief summary

Oral clofarabine is related to two intravenous chemotherapy drugs used for this disease and works in two different ways. It affects the development of new cancer cells by blocking two enzymes that cancer cells need to reproduce. When these enzymes are blocked, the cancer call can no longer prepare the DNA needed to make new cells. Clofarabine also encourages existing cancer cells to die by disturbing components within the cancer cell. This causes the release of a substance that is fatal to the cell. This trial studies the efficacy of oral clofarabine in the treatment of relapsed non-Hodgkin lymphomas.

Detailed description

* Each treatment cycle lasts four weeks during which time the participant will be taking study drug for the first three weeks only. Participants will be supplied with a study medication-dosing calendar for each treatment cycle. * Clofarabine is a tablet that will be taken orally in the morning once daily on days 1 through 21 of each 28-day cycle. Participants can receive up to a total of 6 cycles if they do not experience any unacceptable side effects and if their cancer does not get worse. * The following tests and procedures will be performed at specified intervals through out the treatment period: blood tests, physical examinations, vital signs, radiological exams and urine tests.
