Study of Cyclophosphamide, Hydroxydaunorubicin, Oncovin, Prednisone (CHOP) With Ofatumumab in Patients With Richter's Syndrome
This trial is active, not recruiting.
|Sponsor||University of Oxford|
|Start date||April 2011|
|End date||February 2015|
|Trial size||35 participants|
|Trial identifier||NCT01171378, 2009-016459-23, OCTO_018, OFT113560|
The purpose of this study is to evaluate Ofatumumab in combination with CHOP (cyclophosphamide, hydroxydaunorubicin (doxorubicin), Oncovin (vincristine), and prednisone/prednisolone, the standard chemotherapy treatment) in induction and maintenance treatment of Richter's Syndrome. This study aims to evaluate the overall response rate to CHOP-O (CHOP in combination with Ofatumumab) according to the Revised Response Criteria for Malignant Lymphoma. The hypothesis would be that treatment with CHOP-O for Richter's Syndrome (RS), shows a difference in overall survival (more people living longer), when compared with the standard treatment of CHOP-R (CHOP chemotherapy plus Rituximab).

Male or female participants at least 18 years old.
- Signed written informed consent prior to performing any study-specific procedures
- Patients with B-CLL and newly diagnosed not previously treated and biopsy proven DLBCL Richter's transformation
- 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.
- 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.
- Women of childbearing potential not willing to use adequate contraception during study and for 12 months after last dose of Ofatumumab. Adequate contraception is defined as abstinence, hormonal birth control or intrauterine devices.
|Official title||Single Arm NCRI Feasibility Study of CHOP in Combination With Ofatumumab in Induction and Maintenance for Patients With Newly Diagnosed Richter's Syndrome|
|Principal investigator||Anna Schuh, MD, PhD, MRCP, FRCPath|
|Description||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. CHOP is the acronym for a chemotherapy regimen, cyclophosphamide, hydroxydaunorubicin (doxorubicin), Oncovin (vincristine), and prednisone/prednisolone) and the R stands for the monoclonal antibody, Rituximab. Ofatumumab, a next generation monoclonal anti CD20 antibody, has proven single agent activity in relapsed/refractory B-CLL and other non-Hodgkin lymphomas. In addition, it has shown a favourable safety profile in the maintenance setting. Therefore, we propose to evaluate Ofatumumab in combination with CHOP in induction and maintenance treatment of patients with RS. The primary objective of the study will be to evaluate overall response rate (ORR) to CHOP-O (CHOP chemotherapy plus Ofatumumab) according to the Revised Response Criteria for Malignant Lymphoma (Cheson). Secondary objectives will be feasibility of recruitment, progression free survival and overall survival, the clinical benefit and changes in patient reported outcome measures, safety and tolerability. This is a multi-centre non-randomised Phase II National Cancer Research Institute (NCRI) feasibility study in 35 patients with newly diagnosed Richter's Syndrome in the UK. CHOP-O will be given for six cycles followed by six cycles of Ofatumumab maintenance treatment every eight weeks and a three months follow-up period. The total duration of recruitment will be 24 months starting from the opening of the first site.|
