Evidence of progressive marrow failure as manifested by the development of, or worsening of, anaemia and/or thrombocytopenia. b. Massive (i.e. 6 cm below the left costal margin) or progressive or symptomatic splenomegaly. c. Massive (i.e. 10 cm in longest diameter) or progressive or symptomatic lymphadenopathy. d. Progressive lymphocytosis with an increase of more than 50% over a 2-month period or lymphocyte doubling time (LDT) of less than 6 months from a baseline value of at least 30x10^9/l and not due to causes other than CLL e.

No prior cytotoxic or targeted therapy for CLL (prior localised radiotherapy is allowed). 3. Full-dose R-FC considered inappropriate for at least one of the following reasons a. Age 75 or greater b. WHO performance status 2 or 3 c. Cardiac impairment (NYHA class II) d. Respiratory impairment (bronchiectasis or moderate COPD) e. Renal impairment (estimated Glomerular Filtration Rate (eGFR) 10-30 ml/min) f. Any other significant co-morbidity or factor that makes R-FC inappropriate 4. Considered able to tolerate Chl at the dose used in the LRF CLL4 trial (10mg/m2 d1-7) 5.

Exclusion criteria: 1. Neutrophil count less than 1.0 x 109/l or platelet count less than 50 x 109/l unless due to CLL 2. Uncontrolled auto-immune haemolytic anaemia or thrombocytopenia 3. Active infection 4. Seropositivity for HIV, HCV or HBV (surface antigen and core antibody) 5. Severe renal impairment (eGFR less than 10ml/min) 6. Serum bilirubin more than 1.5 the upper limit of normal unless due to CLL or Gilbert’s syndrome. 7. Serum ALT or AST more than 2.5 the upper limit of normal unless due to CLL 8.

Severe cardiac disease including unstable angina, acute myocardial infarction within six months prior to study entry, congestive heart failure (NYHA III-IV) and arrhythmias (excluding extrasystoles or minor conduction abnormalities) unless controlled by therapy. 20. Any serious underlying medical or psychological conditions, which could impair the ability of the patient to participate in the trial or compromise ability to give informed consent 21. Treatment within a clinical trial within 30 days prior to trial entry. 22. Adult patient under tutelage (not competent to sign informed consent). 23. Pregnant or lactating women. 24. Women of childbearing potential, including women whose last menstrual period was less than one year prior to screening, unable or unwilling to use adequate contraception from study start to one year after the last dose of protocol therapy.

Design outcomes

Primary

MeasureTime frame
Secondary Objective: To compare between the two treatment groups: a. Response including MRD negativity b. Duration of response c. Overall survival d. Time to treatment failure e. Toxicity f. Treatment dose administered g. Quality of life h. Health economic analysis i. Co-morbidity assessment j. Frailty assessment k. Predictive value of biomarkers In addition, treatment outcome will be analysed across biological subgroups defined by co-morbidity/frailty scores and laboratory biomarkers. ;Primary end point(s): Progression-free survival (progression or death from any cause).;Timepoint(s) of evaluation of this end point: End of trial.;Main Objective: To assess whether progression free survival (PFS) time (i.e. the length of time during and after medication or treatment during which the disease being treated does not get worse) using ofatumumab plus bendamustine is longer than that using ofatumumab plus chlorambucil.
