Brief Summary:

The primary objective for this study is to determine the safety profile of radiotherapy and durvalumab, a PD-L1 inhibitor.

Primary endpoint:

Toxicity, drug pharmacokinetics (PK), maximum tolerated dose (MTD) and recommended phase two dose (RPTD) of simultaneous radiotherapy plus durvalumab in patients with relapsed or refractory DLBCL or FL.

Secondary endpoints:

  • ORR
  • Progression-free survival
  • Overall survival

Exploratory endpoints include description of biological effects of combination radiotherapy plus durvalumab (Imaging results, immune function, PK and PD-see 'research methodologies') and in the PET-Sub-Study, biodistribution of 89Zr Durvalumab and 89Zr-IAB22M2C.

Condition or disease Intervention/treatment Phase
Diffuse Large B Cell Lymphoma Follicular Lymphoma Drug: Durvalumab Radiation: Radiotherapy Radiation: Radiotherapy (cohort 6 only) Phase 1

Detailed Description:

Diffuse large B cell lymphoma (DLBCL) and Follicular Lymphoma (FL) are the most common non Hodgkin lymphomas. Standard first line treatment achieves cure in approximately half of patients. However 30% die from relapsed lymphoma.

Durvalumab (an antibody which blocks programmed cell death ligand 1) and other immunotherapies fight cancer by blocking barriers to immune system activity. Immune control of lymphoma provides the prospect of cure, even when chemotherapy has failed. Radiotherapy has striking effects on the immune system and can boost responses to these immunotherapies. The effect of concurrent radiotherapy and durvalumab in DLBCL and FL is unproven.

This study will evaluate the safety and effect of simultaneous radiotherapy plus durvalumab (a PD-L1 inhibitor) in relapsed DLBCL and FL patients.

Arm Intervention/treatment
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.

Drug: 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.

Other Name: MEDI4736

Radiation: 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.

Radiation: Radiotherapy (cohort 6 only)

Cohort 6 patients (only) will receive:

Day 8-Day 10: External Beam Radiotherapy to target site(s)- daily (ie. 5 further fractions to a total of 10 fractions)

Primary Outcome Measures :
  1. 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). [ Time Frame: First 28 days of treatment ]

    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.

Secondary Outcome Measures :
  1. Response rates (according to the Lugano classification for Response Criteria for Non-Hodgkin Lymphoma) [ Time Frame: 0-12 months ]
    Response rates

  2. Progression free survival [ Time Frame: From ceasing treatment annually up to 5 years ]
    Progression free survival in patients who cease treatment due to toxicity.

  3. Overall survival [ Time Frame: Every 6 months from PD up to two years. ]
    Overall survival

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

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

Histologically proven CD20-positive relapsed or refractory diffuse large B cell non-Hodgkin lymphoma (DLBCL) either de novo or DLBCL transformed from any indolent B-non-Hodgkin lymphoma (including Richter's transformation) Or follicular lymphoma grade 1-3A, or Grade 3B, according to the current World Health Organization classification 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 a specific histology.
  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. Patients with DLBCL must not be eligible or 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).

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.

  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 exists.

(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.) n) Signed written informed consent before any trial-related procedure is undertaken that is not part of the standard patient management.
