ClinConnect Summary

Richter's Syndrome (RS) is a high-grade transformation that occurs in 5-15% of patients with B cell chronic lymphocytic leukaemia (B-CLL). RS is a complication of B-CLL in which the leukemia changes into a fast-growing diffuse large B cell lymphoma (DLBCL). The pathogenesis (mechanism by which the disease is caused) of RS is poorly understood and predictors of transformation and response to treatment are unknown. Management of RS remains unsatisfactory; the mean overall survival of patients treated with conventional chemo-immunotherapy such as CHOP-R is 8 months from the end of treatment.

• • Computerized tomography (CT) scan performed within 6 weeks prior to starting treatment.
• • ECOG (Eastern Cooperative Oncology Group) Performance Status of 0, 1, 2 or 3
• • Age 18 years and over.
• Exclusion Criteria:
• • CHOP or CHOP-like anthracycline containing treatment for DLBCL within 6 months prior to registration.
• • Known central nervous system (CNS) involvement of B-CLL.
• • Any malignancy that requires active treatment with the exception of basal cell carcinoma and non-invasive squamous cell carcinoma.
• • Chronic or ongoing active infectious disease requiring systemic treatment such as, but not limited to, chronic renal infection, chronic chest infection with bronchiectasis, tuberculosis and active hepatitis.
• * Subjects meeting any of the following criteria must not be enrolled in the study:
• • Positive serology for Hepatitis B (HB) defined as a positive test for HBsAg (the surface antigen of the Hepatitis-B-Virus). In addition, if negative for HBsAg but HBcAb (Hepatitis B core Antibody) positive (regardless of HBsAb status), a HB DNA test will be performed and if positive the subject will be excluded. Consent will be sought prior to any test being performed.
• • Clinically significant cardiac disease including unstable angina, uncontrolled congestive heart failure, and arrhythmia requiring therapy, with the exception of extra systoles or minor conduction abnormalities.
• • Significant concurrent, uncontrolled medical condition including, but not limited to, renal, hepatic, haematological, gastrointestinal, endocrine, pulmonary, neurological, cerebral or psychiatric disease.
• • History of significant cerebrovascular disease in last 6 months.
• • Known Human immunodeficiency virus (HIV) positive.
• • Known or suspected hypersensitivity to components of investigational product.
• • Patients who have received treatment with any non-marketed drug substance or experimental therapy within 4 weeks prior to Visit 2 (start of treatment, cycle 1, day 1).
• • Current participation in any other interventional clinical study.
• • Patients known or suspected of not being able to comply with a study protocol (e.g. due to alcoholism, drug dependency or psychological disorder).
• • Breast feeding women or women with a positive pregnancy test at screening.
