• Evidence of significant, uncontrolled concomitant diseases that could affect compliance with the protocol or interpretation of results or that could increase risk to the patient, including renal disease that would preclude chemotherapy administration or pulmonary disease (including obstructive pulmonary disease and history of bronchospasm)
• Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection (excluding fungal infections of nail beds) at study enrollment, or any major episode of infection requiring treatment with IV antibiotics or hospitalization (relating to the completion of the course of antibiotics) within 4 weeks prior to Cycle 1, Day 1

• Patients with occult or prior HBV infection (defined as positive total hepatitis B core antibody \[HBcAb\] and negative HBsAg) may be included if HBV DNA is undetectable. These patients must be willing to undergo monthly DNA testing.
• Receipt of live-virus vaccines within 28 days prior to the initiation of study treatment or need for live-virus vaccines at any time during study treatment
• Recent major surgery (within 6 weeks prior to the start of Cycle 1, Day 1) other than for diagnosis

Más betegség

• Known hypersensitivity to any of the study drugs
• History of other malignancy that could affect compliance with the protocol or interpretation of results
  • Patients with a history of curatively treated basal or squamous cell carcinoma or Stage 1 melanoma of the skin or in situ carcinoma of the cervix are eligible.
  • Patients with a malignancy that has been treated with surgery alone with curative intent will be included. Individuals in documented remission without treatment for (\> / =) 2 years prior to enrollment may be included at the discretion of the investigator.
• Clinically significant history of liver disease, including viral or other hepatitis, current alcohol abuse, or cirrhosis
• Presence of positive test results for hepatitis B virus (HBV), hepatitis B surface antigen (HBsAg), or hepatitis C (HCV) antibody
• Patients who are positive for HCV antibody must be negative for HCV by polymerase chain reaction (PCR) to be eligible for study participation
• Known infection with human T-cell leukemia virus 1 (HTLV-1)
• Patients with uncontrolled HIV infection
• Malabsorption syndrome or other condition that precludes enteral route of administration
• Known allergy to both xanthine oxidase inhibitors and rasburicase

Laborértékek

• Pregnant or lactating, or intending to become pregnant during the study Women of childbearing potential must have a negative serum pregnancy test result within 21 days prior to initiation of study drug.

Egyéb

• Richter's transformation confirmed by biopsy

• Signed Informed Consent Form
• Ability and willingness to comply with the requirements of the study protocol
• Patient must have diagnosis of CLL that meets published 2008 IWCLL NCI-WG criteria.
• Patient must have relapsed/refractory disease with an indication for treatment.
• Patient must have an Eastern Cooperative Oncology Group (ECOG) performance score of ≤ 2
• Adequate hematologic function (unless caused by underlying disease, as established by extensive bone marrow involvement or as a result of hypersplenism secondary to the involvement of the spleen by lymphoma per the investigator) defined as follows:
  • Hemoglobin (\> / =) 9 g/dL
  • Absolute neutrophil count (\> / =) 1.0 x 109/L
  • Platelet count (\> / =)75 x 109/L
• Adequate renal function, as indicated by:
  • Calculated creatinine clearance ≥ 30 mL/min using 24-hour Creatinine Clearance or modified Cockcroft-Gault equation (eCCR; with the use of ideal body mass \[IBM\] instead of mass)
• Adequate liver function, as indicated by:
  • AST or ALT (\< / =) 2.5 x ULN
  • Total bilirubin \< 1.5 x ULN (or (\< / =) 3 x ULN for patients with documented Gilbert syndrome)
• Female patients who are not of child-bearing potential and female patients of child-bearing potential who have a negative serum pregnancy test within 3 days prior to Cycle 1, Day 1.
• Patients with HIV infection could be included in the study, as long as their disease is under control on anti-retroviral therapy. Precautions should be taken to modify their HAART regimen to minimize drug interaction
• Warfarin is considered a cautionary medication. Patients on warfarin will be encouraged to replace warfarin with other anticoagulants if possible. If it is not possible or patient is not willing to switch, they could still be included in the study with caution.
