| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| To evaluate the efficacy of fostamatinib (200 mg bid) in patients with relapsed or refractory DLBCL, by assessing overall response rate (ORR) |  | 
| E.2.2 | Secondary objectives of the trial | 
| * To evaluate ORR and durable response rate (DRR) of patients with two distinct molecular subtypes of relpased or refractory DLBCL; B-cell receptor activation positive (BCA+) and B-cell receptor activation negative (BCA-). Several BCA signatures may be considered and selected signature(s) will be evaluated in a further study * To further evaluate the efficacy of fostamatinib (200 mg bid) in patients with relapsed or refractory DLBCL, by assessing duration of response (DoR) & progression free survival
 * To further evaluate the safety and tolerability of fostamatinib (200 mg bid) in the treatment of patients with relapsed or refractory DLBCL
 * To characterise the pharmacokinetics (PK) of R940406 (R406), the active metabolite of fostamatinib
 
 |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria |

 * Measurable disease as defined by Cheson et al 2007 criteria
 * One fresh pre-treatment excisional or core needle biopsy from suitable and accessible site
 * World Health Organization (WHO) performance status 0 to 1
 |  | 
| E.4 | Principal exclusion criteria | 
| * Treatment with nitrosurea, mitomycin C, investigational agents or study drugs w/in28 days of first dose of study treatment, any other chemotherapy, immunotherapy or anticancer agents w/in 3 weeks of first dose of study treament, previous fostamatinib * With the exception of alopecia, any unresolved toxicities from prior therapy or surgery greater than Common Terminology Criteria for Adverse Events (CTCAE) Grade 1
 * Uncontrolled hypertension (defined as >140mmHg systolic and/or > 90 mmHG diastolic at baseline with or without antihypertensive therapy)

 4) Safety will be assessed in terms of adverse events, other significant adverse events,  laboratory data/vital signs collected at all visits (Week 0, 1,2,3,4,8,12,16,20,44)
 5) Before dosing, and at 1, 2, 4 and 8 hours after dosing on days 1, 8, and 29 and at each clinic visit every 8 to 16 weeks.  Pts who have dose reduced will have one post dose PK sample drawn 1 to 4 hours after receiving their first treatment at lower dose leve
