Study information
Scientific title
Single arm NCRI feasibility study of Cyclophosphamide, Hydroxydaunorubicin, Oncovin, Prednisone (CHOP) in combination with Ofatumumab in induction and maintenance for patients with newly diagnosed Richters syndrome
Acronym
CHOP-OR
Study hypothesis
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 NCRI feasibility study in 35 patients with newly diagnosed RS 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.
Richters 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. The pathogenesis 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, the aim of this study is to evaluate Ofatumumab in combination with CHOP in induction and maintenance treatment of patients with RS.

Condition
Topic: National Cancer Research Network; Subtopic: Haematological Oncology, Lymphoma; Disease: Leukaemia (chronic), Lymphoma (non-Hodgkin's)
Intervention
CHOP-O (CHOP with Ofatumumab), Subjects will be given CHOP in combination with ofatumumab (CHOP-O).
CHOP-O is CHOP (cyclophosphamide, hydroxydaunorubicin (doxorubicin), Oncovin (vincristine), and prednisone/prednisolone) in combination with the monoclonal antibody, ofatumumab.
The first 4 infusions of CHOP will be weekly. CHOP-O will be given every 3 weeks for six cycles during induction. Subjects will then receive ofatumumab maintenance treatment once every eight weeks for 6 cycles.; Follow Up Length: 3 month(s); Study Entry : Registration only
