E.3 | Principal inclusion criteria |
Subjects eligible for enrollment in the study must meet all of the following criteria:
1. Small lymphocytic lymphoma (SLL), lymphoplasmacytic lymphoma, marginal zone lymphoma, and follicular lymphoma; grades 1, 2 and 3A, defined according to World Health Organization guidelines. Subjects with a diagnosis of SLL who have a peripheral blood monoclonal B lymphocyte count of ≥5,000/µL are considered to have CLL and are not eligible for this study.
• Tumor verified to be CD20+ positive from a previous or current tissue biopsy.
•CT imaging in screening phase (based on local evaluation) showing 2 or more clearly demarcated lesions/nodes with a long axis >1.5 cm and short axis ≥ 1.0 cm or 1 clearly demarcated lesion/node with a long axis >2.0 cm and short axis ≥1.0 cm (Section 6.2.5 of Study Protocol). CT imaging performed at screening as baseline image.
2. Indolent B-cell NHL with failure to achieve at least a partial response lasting 6 months beyond the end of treatment with rituximab or a rituximab-containing regimen (See Section 6.2.5.4– Section 6.2.5.5 of study protocol for details on response criteria), i.e.:
•Stable disease (SD) after rituximab or a rituximab-containing regimen (imaging will support this finding. NOTE: in cases of SD after rituximab monotherapy as induction treatment, the minimum time to confirm SD by imaging is 60 days from start of first rituximab infusion) or,
• Disease progression during or within 6 months of treatment with rituximab or a rituximab-containing regimen. Imaging must support this finding and will be done ≤ 6 months after the last infusion of rituximab. Note: Subjects must have received a minimum of 4 rituximab infusions as monotherapy or 3 infusions as part of rituximab-containing combination regimens
3. ECOG Performance Status of 0, 1, or 2
4. Age ≥ 18 years
5. Life expectancy of at least 6 months
6. Signed written informed consent prior to performing any study-specific procedures
French subjects: In France, a subject will be eligible for inclusion in this study only if either affiliated to or a beneficiary of a social security category |
|
E.4 | Principal exclusion criteria |
Subjects meeting any of the following criteria will not be enrolled in the study:
1. Grade 3b FL or evidence that the indolent lymphoma has transformed to aggressive lymphoma as verified by biopsy confirmation
2. Previous autologous stem cell transplant in the last 6 months or previous allogeneic stem cell transplant at any time.
3. High dose steroids ≥ 25 mg prednisolone/day (or equivalent) for 7 consecutive days, given as concomitant medication, within 3 months prior to randomization. No more than 10 mg prednisone daily at the time of randomization
4. Prior bendamustine treatment within 1 year of randomization not resulting in a CR or PR for at least 6 months
5. Prior use of any monoclonal antibody (other than anti-CD20) within 3 months prior to randomization
6. Known central nervous system (CNS) involvement by indolent lymphoma
7. Other past or current malignancy. Subjects who have been free of malignancy for at least 5 years, or have a history of definitively treated non-melanoma skin cancer, or successfully treated in situ carcinoma, are eligible*
8. Chronic or current active infectious disease requiring systemic antibiotics, antifungal, or antiviral treatment such as, but not limited to, chronic renal infection, chronic chest infection with bronchiectasis, tuberculosis, and active Hepatitis C
9. Clinically significant cardiac disease as judged by the investigator including unstable angina, acute myocardial infarction within 6 months of randomization, congestive heart failure, and arrhythmia requiring therapy
10. History of significant cerebrovascular disease or event with significant symptoms or sequelae
11. Significant concurrent, uncontrolled medical condition that in the opinion of the investigator or GSK medical monitor contraindicates participation this study
12. Positive serology for Hepatitis B (HB) defined as a positive test for Hepatitis B surface antigen (HbsAg). In addition, if negative for HBsAg but Hepatits B core antibody (HBcAb) positive (regardless of HBsAb status), a HBV DNA test will be performed and if positive the subject will be excluded
● Consult with a physician experienced in care and management of subjects with Hepatitis B to manage/treat subjects who are anti-HBc positive
● If HBV DNA is negative, subject may be included but must undergo HBV DNA monitoring (see Section 6.5.7.1 of study protocol). Prophylactic antiviral therapy may be initiated at the discretion of the investigator
13. Current active liver or biliary disease (subjects with Gilbert’s syndrome or asymptomatic gallstones, liver metastases related to indolent NHL or otherwise stable chronic liver disease per investigator assessment, are eligible)
14. Known human immunodeficiency virus (HIV) positive
15. Screening laboratory values:
● platelets < 100 x 109/L (unless due to indolent lymphoma involvement of the bone marrow)
● neutrophils < 1.5 x 109/L (unless due to indolent lymphoma involvement of the bone marrow)
● Serum creatinine > 1.5 times the institution’s upper limit of normal (ULN); subjects with a serum creatinine > 1.5 ULN will be eligible if the calculated creatinine clearance [Cockcroft, 1976] or creatinine clearance from a 24- hour urine collection is 40 mL/min
● Total bilirubin > 1.5 times ULN (unless due to liver involvement by FL or Gilbert’s disease)
● Transaminases > 3 times ULN
16. Known or suspected hypersensitivity to ofatumumab, bendamustine, or mannitol
17. Treatment with any known non-marketed drug substance or experimental therapy within 5 terminal half-lives or 4 weeks prior to Visit 1, whichever is longer or currently participating in any other interventional clinical study
18. Known or suspected inability to comply with study protocol
19. Lactating women, women with a positive pregnancy test at Visit 1 or women (of childbearing potential) as well as men with partners of childbearing potential, who are not willing to use adequate contraception from study start through one year following last treatment dose. Adequate contraception is defined as abstinence, oral hormonal birth control, hormonal birth control injections, implants of levonorgestrel, estrogenic vaginal ring, percutaneous contraceptive patches, intrauterine device, and male partner sterilization if male partner is sole partner for that subject. The double barrier method can be used in regions where considered acceptable and adequate (condom and/or occlusive cap plus spermicidal agent, as per local acceptable standards)
*Subjects can participate in the study if in the opinion of the investigator and medical monitor it is thought not to affect the subject’s safety, the conduct of the study or the interpretation of the data |
