4.1. Evidence of progressive marrow failure as manifested by the development of, or worsening of, anaemia and/or thrombocytopenia.
4.2. Massive (i.e. 6 cm below the left costal margin) or progressive or symptomatic splenomegaly
4.3. Massive nodes (i.e. 10 cm in longest diameter) or progressive or symptomatic lymphadenopathy
4.4. Progressive lymphocytosis with an increase of more than 50% over a 2-month period or lymphocyte doubling time (LDT) of less than 6 months as long as the lymphocyte count is over 30 x 10^9/L
4.5. A minimum of any one of the following disease-related symptoms must be present:
4.5.1. Unintentional weight loss more than or equal to 10% within the previous 6 months.
4.5.2. Significant fatigue (i.e. Eastern Cooperative Oncology Group PS 2 or worse; cannot work or unable to perform usual activities)
4.5.3. Fevers of greater than 38.0°C for 2 or more weeks without other evidence of infection
4.5.4. Night sweats for more than 1 month without evidence of infection

6. World Health Organisation (WHO) performance status (PS) of 0, 1 or 2
7. Able to provide written informed consent
8. Biochemical values must be within the following limits within 14 days prior to randomization and at baseline:
8.1. Alanine aminotransferase (ALT) 3 x upper limit of normal (ULN). Aspartate aminotransferase (AST) 3 x ULN.
8.2. Total bilirubin = 1.5 x ULN, unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin
For the genetically high-risk pathway
1. TP53 abnormality confirmed by central laboratory
2. At least 18 years old (no upper limit)
3. Meeting all the inclusion criteria for the standard risk pathway stated, with the exception of ‘considered fit for treatment with FCR as determined by the treating clinician’

7. Concomitant warfarin or equivalent vitamin K inhibitor - added 29/06/2017: or other oral anticoagulant treatment; anyone requiring anticoagulation treatment for greater than 6 months is not eligible for trial entry
8. Pregnancy, lactation or women of child-bearing potential unwilling to use medically approved contraception whilst receiving treatment and for 12 months after treatment with rituximab has finished, or 30 days after treatment with ibrutinib has finished, whichever is latest. Women must agree to not donate eggs (ova, oocytes) for the purposes of assisted reproduction
9. Men whose partners are capable of having children but who are not willing to use appropriate medically approved contraception whilst receiving treatment and for 12 months after treatment with rituximab has finished, or 3 months after treatment with ibrutinib has finished, whichever is latest, unless they are surgically sterile
10. CNS involvement with CLL
11. Symptomatic cardiac failure not controlled by therapy, or unstable angina not adequately controlled by current therapy (in patients with a significant cardiac history the left ventricular function should be assessed and patients with severe impairment should be excluded)
12. Respiratory impairment (bronchiectasis or moderate COPD)
13. Other severe, concurrent diseases or mental disorders that could interfere with their ability to participate in the study
14. Inability to swallow oral medication

16. Known HIV positive
17. Positive serology for Hepatitis B (HB) defined as a positive test for HBsAg. In addition, if negative for HBsAg but HBcAb positive (regardless of HBsAb status), a HB DNA test will be performed and if positive the subject will be excluded
18. Positive serology for Hepatitis C (HC) defined as a positive test for HCAb, in which case reflexively perform a HC RIBA immunoblot assay on the same sample to confirm the result
19. History of prior malignancy, with the exception of the following:
