Study type
Description of intervention(s) / exposure
Treatment: Drugs - Durvalumab
Treatment: Other - Radiotherapy

Experimental: Radiotherapy plus Durvalumab - A minimum of 3 patients will initially be enrolled in each cohort of this arm. Patients will be allocated to a radiotherapy dose and site cohort from the schedule at registration. There will be no intra-patient dose or site escalations.
Cohorts will escalate in number of anatomical sites of radiotherapy and dose of radiotherapy given subject to safety. Durvalumab will be administered at a fixed dose every 4 weeks IV.

Treatment: Drugs: Durvalumab
All patients will receive:
Day 1-Day 5: External Beam Radiotherapy to target site(s)-daily for 5 days (i.e. 5 fractions).
D2: Commence durvalumab. Continue 4-weekly until disease progression. Patients can continue until a second radiological progression if clinical benefit is ongoing.

Treatment: Other: Radiotherapy
All patients will receive:
Day 1-Day 5: External Beam Radiotherapy to target site(s)-daily for 5 days (i.e. 5 fractions).
D2: Commence durvalumab. Continue 4-weekly until disease progression. Patients can continue until a second radiological progression if clinical benefit is ongoing.

Primary outcome [1] 0 0
Number of participants treated with radiotherapy and durvalumab with treatment-related adverse events as assessed using CTCAE v4.0. To determine the maximum tolerated dose (MTD). - A minimum of 3 patients will initially be enrolled in each cohort, if none of the first 3 patients experiences a dose limiting toxicity (DLT), the doses in that cohort will be deemed safe and tolerable and escalation may continue. DLTs will be grade 4 neutropenia or thrombocytopenia, grade 3 hemolysis, grade 4 immune related AEs.
If 1 of the first 3 evaluable patients in a cohort experiences a DLT, the cohort will be expanded to at least 6 patients. If there are no further DLTs in the first 6 DLT-evaluable patients, the doses in that cohort will be deemed safe and tolerable and escalation may continue.
If a DLT is observed in = 33% of patients (e.g., 2 or more of up to 6 patients), the dose combination at which this occurs will be considered intolerable and the MTD will have been exceeded for radiotherapy If the MTD is exceeded in any cohort, the highest dose combination at which fewer than 33% experience a DLT will be declared the combination MTD.

Key inclusion criteria
1. Male or Female subjects aged 18 years weighing more than 30 kg

2. Histologically proven CD20-positive relapsed or refractory diffuse large B cell
non-Hodgkin lymphoma (DLBCL) either de novo or DLBCL transformed from follicular
lymphoma, according to the current World Health Organization classification26 on
tissue biopsy. Archived tissue is permitted however must have been obtained after the
last known therapy. The Trial Management Group retains the option to limit the number
of participants enrolled with transformed FL.

3. At least 1 line of previous treatment for lymphoma which must include a CD20
monoclonal antibody such as rituximab, with no curative option as determined by the
investigator. Prior radiotherapy is permitted.

4. Not eligible or not willing to receive high-dose (myeloablative) chemotherapy (HDC)
and autologous stem cell transplant (ASCT) OR has received prior ASCT.

5. Eastern Collaborative Oncology Group performance status 0, or 1, unless attributable
to lymphoma in which case patients of performance status 2 are also eligible.

6. Patients must have measurable disease (at least one bi-dimensionally measurable site
of disease that has not been previously irradiated OR has progressed after
radiotherapy: nodal disease >1.5 cm or an extranodal lesion > 1.0 cm in longest
perpendicular diameter). At least three disease sites must be FDG-avid on PET imaging
AND amenable to radiotherapy according to local radiation oncology investigator

7. One site of disease must be amenable to biopsy. It is preferable that this is a site
not planned for radiotherapy, but not mandated. A fresh tumor biopsy collected during
screening and /or archival tumor tissue collected after the last relapse/disease
progression (material which has been collected before the last line of treatment is
not accepted). In addition, a sufficient amount of the material is required for
acceptance of the archival material. If neither condition occurs, a fresh tumor biopsy
needs to be performed as stated above.

8. Adequate bone marrow function with platelets > 50 x109/l; neutrophils > 1.0x109/l at
the time of study entry unless attributed to bone marrow infiltration by lymphoma.

9. Adequate renal function defined by an estimated creatinine clearance = 30 mL/min
according to the Cockcroft-Gault formula (or local institutional standard method).

10. Adequate hepatic function defined by a total bilirubin level = 2 × the upper limit of
normal (ULN) range (excluding Gilbert's disease where a level of = 3 ×ULN is
acceptable) and AST and alanine aminotransferase (ALT) levels = 2.5 × upper limit of
institutional normal range unless attributed to lymphoma.

11. No concurrent uncontrolled medical condition as determined by the investigator.

12. Life expectancy > 3 months.

13. Negative blood pregnancy test at screening for women of childbearing potential.
Effective contraception for both male and female subjects if the risk of conception

(Note: The effects of the trial drug on the developing human fetus are unknown; thus,
women of childbearing potential and men must agree to use effective contraception,
defined as 2 barrier methods, or 1 barrier method with an intrauterine device, or use
of oral female contraceptive. Should a woman become pregnant or suspect she is
pregnant while she or her partner is participating in this trial, the treating
physician should be informed immediately. Effective contraception at least 30 days
prior and up to 3 months after treatment is required for all women of childbearing
potential and male subjects will be advised not to father a child during the 3 months
after treatment completion. Male subjects will be requested to seek advice on
conservation of sperm prior to treatment.)

14. Signed written informed consent before any trial-related procedure is undertaken that
is not part of the standard patient management.
Minimum age
18 Years
Maximum age
