Not accepted
You may be eligible if
1. Patients with histologic diagnosis for one of the following histologies according to the World Health Organization: documented at initial diagnosis or at relapse:
* Previous indolent lymphoma (follicular lymphoma, marginal zone lymphoma, including extranodal MALT lymphoma, lymphoplasmacytoid lymphoma) with transformation to diffuse large B-cell lymphoma at relapse (biopsy proof of transformation is mandatory);
* Follicular lymphoma grade 3B;
* Biopsy proof of disease at initial diagnosis is mandatory. A biopsy at relapse is mandatory. A histological diagnosis (core or excisional biopsy) is strongly encouraged; a cytological diagnosis is acceptable only in the event that tissue cannot be obtained.
Patients must be CD20+ in order to be eligible for the study.
2. Clinically and/or radiologically measurable disease (1 site bidimensionally measurable). Measurements/ evaluations must be done within 28 days prior to registration.
Baseline FDG-PET scan, if available, must be positive (known FDG-avid lymphoma)
3. Patient must have had at least one previous regimen of therapy for their disease. Patients must have relapsed or progressed after R-CHOP chemotherapy or equivalent.
4. Patient age is ≥16 years. Patients older than 70 years of age are not recommended for this study. (Note that the lower age limit at each centre will be determined by that centre's policy regarding the age at which an individual may sign his or her own consent.)
5. ECOG performance status of 0, 1, 2 or 3.
6. Patient must be considered fit for intensive chemotherapy and ASCT and an appropriate candidate to receive salvage chemotherapy and ASCT.
7. Laboratory Requirements: (must be done within 14 days of registration)
Hematology:
* Granulocytes (AGC) \> 1.0 x 109/L (independent of growth factor support)
* Platelets \> 100 x 109/L (50 x 109/L if bone marrow involvement by lymphoma, independent of transfusion support)
Biochemistry:
* AST and ALT \< 3x ULN
* Serum total bilirubin \< 1.5x ULN (≤ 5x ULN if Gilberts Disease)
* Serum Creatinine \< 1.5x ULN (or estimated GFR of ≥40 mL/min/1.73m2 using Cockcroft Gault formula)
* International normalized ratio (INR) \> 1.5 × the ULN in the absence of therapeutic anticoagulation
* Partial thromboplastin time (PTT) or activated partial thromboplastin time (aPTT)
* \> 1.5 × the ULN in the absence of a lupus anticoagulant
8. A Women of childbearing potential (WOCBP) is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) and is not postmenopausal. Menopause is defined as 12 months of amenorrhea in a woman over age 45 years in the absence of other biological or physiological causes. Women of child bearing potential (who are heterosexually active) and men (who are sexually active with WOCBP), must be practicing a highly effective method of birth control (Pearl Index \<1) such as oral contraceptives, intrauterine device, sexual abstinence or barrier method of contraception in conjunction with spermicidal jelly during study treatment and in female patients for 18 months after end of antibody treatment Men must agree to not donate sperm during and after the study. These restrictions apply for 18 months after the last dose of study drug.
Women of childbearing potential must have a pregnancy test taken (either by serum beta-human chorionic gonadotropin \[β-hCG\]) or urine) and proven negative within 14 days prior to registration.
Women who are pregnant or breastfeeding are ineligible for this study.
9. Patient consent must be appropriately obtained in accordance with applicable local and regulatory requirements. Each patient must sign a consent form prior to enrollment in the trial to document their willingness to participate.
10. Patients must be accessible for treatment and follow-up. Patients randomized on this trial must be treated and followed at the participating centre. Investigators must assure themselves the patients randomized on this trial will be available for complete documentation of the treatment, response assessment, adverse events, and follow-up.
11. Protocol treatment is to begin within 5 working days of patient registration
8. Patients who have been vaccinated with live, attenuated vaccines within 4 weeks prior to registration.
9. Known history of stroke or intracranial hemorrhage within 6 months prior to registration.
10. Clinically significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias, congestive heart failure, or myocardial infarction within 6 months of Screening, or any Class 3 (moderate) or Class 4 (severe) cardiac disease as defined by the New York Heart Association Functional Classification.
11. Any serious active disease or co-morbid medical condition, including psychiatric illness, judged by the local investigator to preclude safe administration of the planned protocol treatment or required follow-up.
12. Any other serious intercurrent illness, life threatening condition, organ system dysfunction, or medical condition judged by the local investigator to compromise the subject's safety, preclude safe administration of the planned protocol treatment or required follow-up, including (for example):
* Active, uncontrolled bacterial, fungal, or viral infection, history of chronic or recurrent infection
* Clinically significant cardiac dysfunction or cardiovascular disease.
You may not be if
1. Patients who have been previously treated with obinutuzumab.
2. Life expectancy \< 90 days
3. Patients with a history of other malignancies, except: adequately treated non-melanoma skin cancer and superficial bladder cancer, curatively treated in-situ cancer of the cervix or breast, or localized excised prostate cancer, other solid tumors curatively treated with no evidence of disease for \> 5 years.
4. Active and uncontrolled central nervous system involvement, meningeal or parenchymal. Patients with CNS disease at initial presentation and who are in a CNS CR at the time of relapse are eligible. MRI scanning and / or lumbar puncture should be performed if there is clinical suspicion of active CNS disease.
5. Patients with symptoms suggestive of Progressive Multifocal Leukoencephalopathy (PML).
6. Major surgery performed within 4 weeks prior to registration.
