  Purpose

The goal of this clinical research study is to find the highest tolerable dose of fludarabine and cytarabine that can be given in combination with oxaliplatin and rituximab in the treatment of chronic lymphocytic leukemia (CLL), prolymphocytic leukemia, or Richter's transformation. Once the highest tolerable dose for this drug combination is found, the next goal of the study will be to find out if this combination therapy is effective in shrinking or slowing the growth of these diseases.

Primary Outcome Measures:
  • Maximum Total Tolerated Dose (MTD) of Daily Combination Fludarabine 30 mg/m^2 and Cytarabine 500 mg/m^2 Among 3 Dose Levels (Dose Level 1: 2 Days, Dose Level 2: 3 Days or Dose Level 3: 4 Days) [ Time Frame: Up to 36 weeks (6 cycles each 4-6 weeks) ] [ Designated as safety issue: Yes ]
    Maximum dose levels for Phase I determined among three possible dose levels of Fludarabine and Cytarabine in combination with fixed doses of Oxaliplatin and Rituximab. Fludarabine and Cytarabine Dose Level 1: Days 2-3 (2 Days); Dose Level 2: Days 2-4 (3 Days); and Dose 3: Days 2-5 (4 Days). MTD is dose level at which less than 2/3 or 2/6 participants experience dose limiting toxicities (DLTs). The number of days of fludarabine and cytarabine administration increased simultaneously. Participants received a subsequent cycle of treatment with 1 additional day of fludarabine and cytarabine treatment no less than 4 weeks from the initiation of the previous cycle if no drug-related grade 3 or 4 non-hematologic life-threatening adverse events, and drug-related non-hematologic toxicity resolved to baseline or < grade 2. A maximum of 6 cycles were administered.


Secondary Outcome Measures:
  • Overall Response: Number of Participants With Complete Remission, Nodular Partial Remission, and Partial Remission [ Time Frame: Up to 36 weeks (6 cycles each 4-6 weeks) ] [ Designated as safety issue: No ]
    Overall Response includes Complete remission (CR), nodular partial remission (nPR), and partial remission (PR) in high-risk, previously untreated participants with Chronic Lymphocytic Leukemia treated with CFAR using National Cancer Institute - Working Group response criteria. CR defined as zero nodes, Liver/spleen not palpable, zero symptoms, polymorphonuclear leukocyte (PMN)>1,500/uL, Platelets >100,000uL, Hemoglobin (untransfused) >11.0g/dL, Lymphocytes <4,000/uL and Bone Marrow Aspirate biopsy <30% lymphocytes with no lymphocyte infiltrate; PR defined as nodes >/= 50% decrease,Liver/spleen >/= 50% decrease, symptoms not applicable, PMN >1,500/uL or >50% improvement from baseline, Platelets 100,000uL or >/=50% decrease improvement from baseline, Hemoglobin (untransfused) >11.0g/dL or >50% improvement from baseline, Lymphocytes >50% decrease and Bone Marrow Aspirate biopsy Not Applicable for PR; with nPR defined same as PR but with <30% lymphocytes with residual disease on biopsy.

  Hide Detailed Description

Detailed Description:

Cytarabine is designed to insert itself into DNA (the genetic material of cells) and stop the DNA from repairing itself.

Oxaliplatin is designed to kill cancer cells by damaging their DNA.

Fludarabine is designed to make cancer cells less able to repair damaged DNA. This may increase the likelihood of the cells dying.

Rituximab is designed to attach to lymphoma cells, which may cause them to die.

During the Phase I portion of the study, researchers will be testing different doses of the study drug combination. Oxaliplatin and rituximab will be given at the same dose level. However, fludarabine and cytarabine will be given daily for 2 days to the first 3 participants, daily for 3 days to the next 3 participants, and daily for 4 days to the next 3 participants. Although the plan is to treat 3, up to 6 participants may be treated in each of these groups.

If participants who receive the fludarabine and cytarabine for 2 or 3 days do not experience intolerable side effects, after the second cycle they may receive the next higher dose (an additional day of fludarabine and cytarabine) for the following cycles.

Once the highest tolerated dose of fludarabine and cytarabine given in combination with oxaliplatin and rituximab is found, the next group of participants entering the study will take part in the Phase II portion of the study. Participants in the Phase II portion will receive the study drugs at the highest tolerated dose found in the Phase I portion of the study. The goal of this part of the study is to look at how effective the drug combination is in treating patients with Richter's syndrome, prolymphocytic leukemia, and aggressive, relapsed, or refractory CLL. The same dose levels for all 4 drugs will be used throughout the Phase II portion of the study, unless intolerable side effects occur. In that case, the dose may be lowered or the treatment may be stopped.

  • Each cycle will be repeated every 4-6 weeks, depending on your blood counts and your medical condition.
  • You will receive oxaliplatin through a needle in your vein over about 2 hours on Days 1-4 of every 28-day study "cycle."
  • You will receive rituximab by vein over about 4-6 hours on Day 3 of the first cycle and on Day 1 on every cycle after that.
  • Starting on Day 2, you will receive fludarabine by vein over about 30 minutes and cytarabine by vein over about 2 hours for 2, 3, or 4 days.
  • On Day 6, you will receive peg-filgrastim subcutaneously (through a needle just under your skin) to help increase your white blood cell count.
  • On the days that you receive the study drugs, you will also be given fluids (such as saline) by vein to keep you from becoming dehydrated. If you receive the treatment as an outpatient, this means that the visit may take up to 8 hours.
  • Additional drugs will be given before each dose of rituximab to lower the risk of side effects. If side effects do occur, rituximab may have to be stopped until the side effects go away, at which point the drug may be restarted. This may make your time in the outpatient area longer.
  • The first study cycle will be given at MD Anderson. Depending on your response, up to 5 more cycles will be given either at MD Anderson or at home with your regular doctor.
  • Every 1-2 weeks, blood samples (about 1 teaspoon each) will be drawn for routine tests.
  • At the end of every cycle, you will have a physical exam and blood (about 1 teaspoon) will be drawn to determine whether you should receive another cycle.
  • You will have a bone marrow biopsy/aspirate at the end of the 3rd and 6th cycles. The biopsy at the end of cycle 3 will be used to determine if you are responding to treatment and will determine whether you should continue to receive the study drug combination.

You may remain on study for up to 6 cycles. You will be taken off-study early if the disease gets worse or intolerable side effects occur.

Once you are no longer receiving treatment, you will have an end-of-treatment visit. At this visit, you will have a physical exam and blood (about 1 teaspoon) will be drawn for routine tests.

If you achieve remission, after your last cycle is complete, you will have blood drawn (about 2 teaspoons each) every 3 months for routine tests. These tests will continue for as long as you are in remission.

This is an investigational study. Fludarabine, cytarabine, oxaliplatin, and rituximab are all FDA approved and commercially available. The use of these drugs together is investigational. Up to 102 patients will take part in this multicenter study. Up to 90 will be enrolled at The University of Texas (UT) MD Anderson Cancer Center.

  • Oxaliplatin, fludarabine, cytarabine or rituximab intolerance.
  • Pregnancy or lactation.
