PRIMARY outcome

Timeframe: From treatment onset to end of each cycle of treatment (every 21 days)

Population: Of the 48 study participants, 19 were enrolled in the Phase I MTD group and included in the MTD analysis.

MTD defined as dose level at which 2/3 or 2/6 participants experience Dose Limiting Toxicity (DLT), where DLTs are any oxaliplatin-related ≥Grade 3 non-hematological toxicity involving a major organ system (brain, heart, kidney, liver, lung) in the National Cancer Institute (NCI) Version 3.0 toxicity scale.

SECONDARY outcome

Timeframe: Evaluation every 3 cycles of treatment (28 days per cycle), approximately 90 days

According to International Workshop Response Criteria for Non-Hodgkin's Lymphomas: Complete remission (CR) defined as \> 30% lymphocytes in the bone marrow, recovery of blood counts and no clinical symptoms; and Partial remission (PR) defined as \> 50% decrease of clinical symptoms from baseline and recovery from blood counts.
