2. Eastern Cooperative Oncology Group performance status 0-2.

3. Patients must have a confirmed diagnosis of lymphoma that is relapsed and/or
refractory after at least 2 prior chemotherapeutic regimens and for which no curative
option exists. Patients with Waldenstrom's macroglobulinemia are not eligible for
enrollment in this study. Patients with Hodgkin lymphoma are considered eligible for
this study.

4. Suitable venous access for PK and pharmacodynamic evaluations.

5. Female patients who are post menopausal, surgically sterile, or agree to practice 2
effective methods of contraception or abstain from heterosexual intercourse.

abstain from heterosexual intercourse.

6. Voluntary written consent must be obtained.

7. Adequate blood and chemistry values during the screening period:

- Absolute neutrophil count (ANC) ≥ 1,500/mm3; platelet count ≥ 100,000/mm3.

- Total bilirubin must be ≤ 1.5 × the upper limit of the normal range upper limit
of normal (ULN).

- Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) must be ≤ 2.5
× the upper limit of normal (ULN). AST and ALT may be elevated up to 5 times the
upper limit of normal if their elevation can be reasonably ascribed to the
presence of metastatic disease.

- Calculated creatinine clearance ≥ 30 mL/minute.

Exclusion Criteria:

1. Peripheral neuropathy ≥ Grade 2.

2. Female patients who are lactating or have a positive serum pregnancy test during the
screening period .

10. Evidence of current uncontrolled cardiovascular conditions, including cardiac
arrhythmias, congestive heart failure (CHF), angina, or myocardial infarction within
the past 6 months.

11. QTc > 470 milliseconds (msec) on a 12-lead electrocardiogram (ECG) obtained during
the screening period.

12. Known human immunodeficiency virus (HIV), hepatitis B or hepatitis C positive.

13. Any serious medical or psychiatric illness that could, in the investigator's opinion,
potentially interfere with the completion of treatment according to this protocol.
