Brief Summary
This study evaluates the addition of Atezolizumab to current therapy of Rituximab, Gemcitabine and Oxaliplatin (R-GemOx) for patients with relapsed or refractory Diffuse Large B-Cell Lymphoma (DLBCL) ...
Detailed Description
Rituximab is a chimeric mouse/human monoclonal antibody that binds to CD20, on pre-B and mature B lymphocytes and eliminates these cells potentially via a number of different mechanisms. The R-GemOx ...
Eligibility Criteria
Inclusion
- Histologically proven CD20 +ve diffuse large B-cell lymphoma with sufficient diagnostic material, obtained either at diagnosis or relapse (the latter is preferable) that is available to forward to the Haematological Malignancies Diagnostic Service (HMDS) for gene expression profiling and central pathology review. (See screening procedure for details on biopsy requirements)
- Refractory to, or relapsed following, first-line or second-line treatments with rituximab concurrently with anthracycline or anthracenedione-based chemotherapy (etoposide or gemcitabine allowed if comorbid).
- Refractory disease must fulfil one of the following:
- Continuing partial response (PR) from termination of first-line treatment. It is strongly recommended the lymphoma be reconfirmed by biopsy however, if these procedures are deemed to be inappropriate, the CI may determine eligibility following review of the imaging results and disease history.
- Continuing stable disease (SD) from termination of first-line treatment. Reconfirmation of the lymphoma by biopsy (preferred) is recommended but not mandatory.
- Progressive disease (PD). Biopsy or reconfirmation of the lymphoma is recommended but not mandatory.
- o Not eligible for high-dose therapy with peripheral blood progenitor cell rescue at Investigator discretion as a result of:
- Age
- Co-morbidity
- Previous HDT. Rationale to be clearly documented on eCRF and medical notes.
- Baseline FDG-PET scans must demonstrate positive lesions compatible with CT defined anatomical tumour sites.
- CT/PET scan showing at least:
- 2 or more clearly demarcated lesions/nodes with a long axis \>1.5cm and short axis ≥1.0cm OR
- 1 clearly demarcated lesion/node with a long axis \>2.0cm and short axis ≥1.0cm.
- Resolution of toxicities from previous therapy to a grade that in the opinion of the investigator does not contraindicate study participation.
- Patients aged 16 years or over.
- Willingness to participate in appropriate pregnancy prevention measures.
- Female patients who are fertile and of childbearing potential must have a negative serum or urine pregnancy test during screening (within 14 days prior to the start of trial treatment) and agree to use two highly effective forms of contraception (oral, injected or implanted hormonal contraception and condom; an intra-uterine device and condom) effective from the first administration of all study drugs, throughout the trial and for 12 months after last dose of study therapy are considered eligible. Unless they are surgically sterile or ≥ 2 years after the onset of menopause.
- Male patients with partners of child-bearing potential who agree to take measures not to father children by using one form of highly effective contraception (oral, injected or implanted hormonal contraception and condom; an intra-uterine device and condom) effective from the first administration of all study drugs, throughout the trial and for 12 months after last dose of study therapy are considered eligible. Male subjects must also refrain from donating sperm during this period. Unless they are surgically sterile.
- Men with pregnant or lactating partners must be advised to use barrier method contraception (for example: condom plus spermicidal gel) to prevent exposure to the foetus or neonate
- Written informed consent using current version of Protocol, Patient Information Sheet and Informed Consent Form.
- ECOG performance status ≤3
Exclusion
- Received any of the following treatments within two weeks prior to start of study therapy (unless otherwise stated):
- Anti-cancer cytotoxics (excluding corticosteroids)
- Radiotherapy unless it is to a limited field to control life/organ-threatening symptoms.
- DLBCL that is refractory to or relapsed within 3 months of a gemcitabine regimen for DLBCL
- Major surgery within 4 weeks of registration.
- Treatment with any known non-marketed drug substance or experimental therapy within 5 terminal half-lives or 4 weeks prior to registration.
- History of stroke or intracranial haemorrhage within 6 months prior to registration.
- Pre-existing peripheral neuropathy grade \>2.
- Clinically significant cardiac disease including unstable angina, acute myocardial infarction within six months prior to registration, congestive heart failure (NYHA III-IV), a current LVEF of \<40%
- Significant concurrent, uncontrolled medical condition that in the opinion of the investigator contraindicates participation in this study
- Known lymphoma involvement of the CNS.
- Known or suspected hypersensitivity to study treatments that in the opinion of the investigator contraindicates their participation. Patients with known history of idiopathic pulmonary fibrosis, organizing pneumonia (e.g., bronchiolitis obliterans), drug induced pneumonitis or idiopathic pneumonitis, or evidence of active pneumonitis will be excluded from study participation.
- Known HIV positivity; positive serology for Hep B (defined as positivity for Hepatitis B surface antigen (HBsAg) or Hepatitis B core antibody (anti-HBc)) or C; chronic or current infectious disease (except evidence of prior vaccination).
- Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection or any major episode of infection requiring treatment with IV antibiotics or hospitalization within 2 weeks of the start of Cycle 1. Suspected active or latent tuberculosis needs to be confirmed by positive interferon gamma (IFN-gamma) release assay.
- Other past or current malignancy within 2 years prior to registration unless in the opinion of the investigator it does not contraindicate participation in the study. Subjects who have a history of completely resected non-melanoma skin cancer, or successfully treated in situ carcinoma, are eligible.
- Screening laboratory values:
- platelets \<75x109/L (unless due to lymphoma involvement of the bone marrow)
- neutrophils \<1.0x109/L (unless due to lymphoma involvement of the bone marrow)
- creatinine \>2.0 times upper normal limit (unless due to lymphoma or unless creatinine clearance \>60mL/min (should be calculated using Cockcroft and Gault equation))
- total bilirubin \>1.5 times upper normal limit (unless due to lymphoma or a known history of Gilbert's disease, no higher than \>3 times upper normal limit)
- ALT/AST \>2.5 times upper normal limit (unless due to lymphoma, no higher than \>5 times upper normal limit)
- alkaline phosphatase \>2.5 times upper normal limit (unless due to lymphoma, no higher than \>5 times upper normal limit)
- Subjects known or suspected of being unable to comply with the study protocol.
- Pregnant or lactating women. Women of childbearing potential must have a negative pregnancy test at screening.
- History of autoimmune disease, including but not limited to myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, vascular thrombosis associated with antiphospholipid syndrome, Wegener's granulomatosis, Sjögren's syndrome, Guillain-Barré syndrome, multiple sclerosis, vasculitis, or glomerulonephritis (Patients with a history of autoimmune-related hypothyroidism on a stable dose of thyroid replacement hormone will be eligible as will be patients with controlled Type I diabetes mellitus on a stable dose of insulin). Patients with eczema, psoriasis, lichen simplex chronicus, or vitiligo with dermatologic manifestations only (e.g., patients with psoriatic arthritis are excluded) are eligible for the study provided all of following conditions are met:
- Rash must cover \<10% of body surface area
- Disease is well controlled at baseline and requires only low-potency topical corticosteroids
- No occurrence of acute exacerbations of the underlying condition requiring psoralen plus ultraviolet A radiation, methotrexate, retinoids, biologic agents, oral calcineurin inhibitors, or high potency or oral corticosteroids within the previous 12 months
- Patients who have previously undergone allogeneic transplantation.
- Vaccination with a live vaccine within 28 days of study treatment or anticipation of need for such a vaccine during the course of the study and up to 5 months after the last dose of atezolizumab.
