The RaDD study: This phase I trial is assessing simultaneous radiotherapy and immunotherapy (with durvalumab) in patients with relapsed Diffuse Large B Cell LymphomaPhase I Dose Escalation Study of Radiotherapy and Durvalumab in Relapsed/Refractory Diffuse Large B-cell Lymphoma (DLBCL)

Clinical summary

Summary

Patients enrolled in this trial will be allocated to a radiotherapy dose and site cohort at registration. There will be no intra-patient dose or site escalations. The number of anatomical sites and dose of radiotherapy will be escalated subject to safety. A fixed dose of durvalumab will be administered intravenously every 4 weeks.

Eligibility

Inclusion

  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 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). At least three disease sites must be FDG-avid on PET imaging AND amenable to radiotherapy according to local radiation oncology investigator review.
  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 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.

Exclusion

  1. T-cell lymphoma, Hodgkin lymphoma.
  2. Central nervous system, meningeal or spinal cord involvement by lymphoma.
  3. Prior therapy with any antibody or drug targeting T-cell coregulatory proteins (immune checkpoints) such as PD-1, PD-L1, or cytotoxic T-lymphocyte antigen-4 (CTLA-4).
  4. Patients with active autoimmune disease that might deteriorate when receiving an immunostimulatory agent:

i) Subjects with diabetes type I, vitiligo, psoriasis, hypo- or hyperthyroid disease not requiring immunosuppressive treatment are eligible ii) Subjects requiring hormone replacement with corticosteroids are eligible if the steroids are administered only for the purpose of hormonal replacement and at doses ≤ 10 mg or 10 mg equivalent prednisone per day iii) Administration of steroids through a route known to result in a minimal systemic exposure (topical, intranasal, intro-ocular, or inhalation) is acceptable.

e) Current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab. The following are exceptions to this criterion: i. Intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection) ii. Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisolone or its equivalent iii. Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication)

.iv.Patients requiring steroids for symptom control during the screening period may receive a single course of prednisolone at a dose of up to 100mg daily (or equivalent) for a maximum of 5 days at the discretion of the local PI. Steroids must not be given within 5 days of radiotherapy. Note that steroids are optimally avoided due to the potential for reduction in durvalumab activity

f) Known severe hypersensitivity reactions to monoclonal antibodies (Grade ≥ 3 NCI-CTCAE v 4.03), any history of anaphylaxis, or uncontrolled asthma (that is, 3 or more features of partially controlled asthma) g) Past history of interstitial lung disease. h) Prior organ transplantation, including allogeneic stem-cell transplantation i) Prior malignancy active within the previous 2 years except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the prostate, cervix, or breast.

j) Major surgery for any reason, except diagnostic biopsy, within 4 weeks of enrolment and/or if the subject has not fully recovered from the surgery within 4 weeks of enrolment k) Any other serious active disease, including but not limited to; i) clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke (< 6 months prior to enrolment), myocardial infarction (< 6 months prior to enrolment), unstable angina pectoris, congestive heart failure (New York Heart Association Classification Class ≥ II), or serious cardiac arrhythmia requiring medication (including QTc prolongation of > 470 ms and/or pacemaker) or prior diagnosis of congenital long QT syndrome.

ii) uncontrolled active infection, iii) uncontrolled diabetes (e.g., haemoglobin A1c ≥ 8.5%) l) Known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS), Hepatitis B virus (HBV) or hepatitis C virus (HCV) infection at screening (positive HBV surface antigen or HCV RNA if anti-HCV antibody screening test positive) m) Medical or psychiatric conditions that compromise the patient's ability to give informed consent.

o) Subject is pregnant, lactating or unwilling/unable to use adequate contraception p) Subject weighs less than 30kg
