Oxaliplatin, Fludarabine, Cytarabine and Rituximab in Richter's Syndrome, Refractory CLL and PLL

This study has been completed.

M.D. Anderson Cancer Center Identifier:
First received: March 23, 2007
Last updated: October 25, 2011
Last verified: October 2011

Primary Objectives:

  1. Determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of oxaliplatin in combination with fludarabine, Ara-C and rituximab in patients with Richter's transformation, prolymphocytic leukemia (PLL), or refractory/relapsed B-cell chronic lymphocytic leukemia (CLL).
  2. Assess the complete response (CR) and partial response (PR) rate to combination therapy of oxaliplatin, fludarabine, Ara-C and rituximab in patients with Richter's transformation, PLL or refractory/relapsed B-cell CLL.
  3. Determine the safety and toxicity profile of combination therapy of oxaliplatin, fludarabine, Ara-C and rituximab in patients with Richter's transformation, PLL or refractory/relapsed B-cell CLL.

Secondary Objectives:

  1. Determine the duration of response, failure-free survival, and overall survival.
  2. Determine the incidence of infections (bacterial, fungal, and viral) in patients with Richter's transformation, prolymphocytic leukemia or refractory/relapsed B-cell CLL treated with rituximab, oxaliplatin, fludarabine and Ara-C; monitor immune parameters such as T cell counts and immunoglobulin levels; and monitor Epstein-Barr virus (EBV) status.
  3. Characterize the pharmacodynamics of oxaliplatin in leukemia cells with respect to total adduct formation, cross-link formation and excision deoxyribonucleic acid (DNA) responses. Compare these parameters in cells from the same patient after treatment with oxaliplatin in combination with fludarabine and Ara-C.

Primary Outcome Measures:
  • Maximum Tolerated Dose (MTD) Oxaliplatin [ Time Frame: From treatment onset to end of each cycle of treatment (every 21 days) ]
    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 Measures:
  • Number of Participants With a Complete Response or Partial Response [ Time Frame: 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.

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Histologically or cytologically confirmed Richter's transformation, fludarabine-refractory chronic lymphocytic leukemia or prolymphocytic leukemia.
  2. Patients must be 18 years of age or older.
  3. Patients must have a performance status of 0-2 (Zubrod scale).
  4. Patients must have adequate renal function (serum creatinine below or equal to 2mg/dL or creatinine clearance greater than 30mL/min), unless renal dysfunction is considered due to organ infiltration by disease.
  5. Patients must have adequate hepatic function (bilirubin less than or equal to 2.0 mg/dl; Serum glutamic oxaloacetic transaminase (SGOT) or serum glutamic pyruvic transaminase (SGPT) less than or equal to 3 times the upper limit of normal (ULN) for the reference lab unless considered due to leukemia or congenital hemolytic disorder (for bilirubin).
  6. Female patients of childbearing potential (including those <1 year post-menopausal) and male patients must agree to use contraception.
  7. Patients must sign an informed consent indicating that they are aware of the investigational nature of this study in keeping with the policies of the hospital.
  8. Patients must have platelet counts greater or equal to 20,000, unless due to disease involvement, or autoimmune disorders.

  3. Pregnancy or lactation.
  4. Chemotherapy and/or radiation therapy within 4 weeks.
  5. Medical condition, including mental illness or substance abuse, deemed by the Investigator to be likely to interfere with a patient's ability to sign informed consent, cooperate and participate in the study, or interfere with the interpretation of the results.
