• Target Recruitment: 978

Inclusion Criteria

1. Subjects with a diagnosis of CD20/and CD22-positive, follicular grade 1-3a lymphoma, who have received 1 or 2 prior regimens, at least 1 of which should have contained administration of rituximab (either as a single agent or in combination). Diagnoses made within 1 year of randomization do not need to be repeated. Maintenance therapy with rituximab should be considered part of the preceding induction regimen.

2. Prior CD20 and /CD22-immunophenotyping of tumors to document B-cell NHL. If such prior documentation is not available, then the immunophenotype of the current disease must be documented by fine-needle aspirate or biopsy, or by circulating CD20 and/CD22-positive NHL cells from peripheral blood before randomization.

3. Age 18 years or older.

4. Eastern Cooperative Oncology Group (ECOG) performance status = 2.

5. Life expectancy = 12 weeks.

6. Absolute neutrophil count (ANC) = 1.5 x 109/L (1500/mL) and platelets = 75 x 109/L (75,000/mL).

7. Serum creatinine = 1.5 x the upper limit of normal (ULN) and urine protein to creatinine ratio of = 0.2.

8. Total bilirubin =1.5 x ULN, AST and alanine aminotransferase (ALT) = 2.5 x ULN.

9. At least 1 measurable disease lesion that is = 1.5 cm x 1.5 cm by computed tomography (CT) or magnetic resonance imaging (MRI) at the time of inclusion, in an area of no prior radiation therapy, or documented progression in an area that was previously irradiated.

10. Negative serum pregnancy test performed within 1 week before administration of the first dose of test article if the subject is a woman of childbearing potential (if the subject is male, this criterion is considered to be met). A woman of childbearing potential is defined as one who is biologically capable of becoming pregnant. This includes women who are using contraceptives or whose sexual partners are either sterile or using contraceptives.

11. Willingness of male and female subjects who are not surgically sterile or postmenopausal to use medically acceptable methods of birth control for the duration of the study, including up to 12 months after the last dose of test article. Sexually active males and females using oral contraceptive pills should also use barrier contraception.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range
F.1.3 Elderly (>=65 years) yes

Exclusion Criteria

1. Subjects with a prior allogeneic hematopoietic stem cell transplant (HSCT).

2. Subjects with clinical evidence of transformation to a more aggressive subtype of lymphoma or gradestage 3B follicular lymphoma.

3. Subjects with prior autologous transplant within 6 months before administration of the first dose of test article.

4. Prior treatment with anti-CD22 antibodies or any previous radio-immuno therapy.

5. Subjects whose disease is primary rituximab refractory, meaning that they did not have a CR or PR or that they experienced disease progression within 6 months after their first dose of rituximab or rituximab containing treatment regimen.

6. Subjects whose disease is otherwise rituximab refractory, meaning that they did not have a CR or PR or had disease progression within 6 months after their first dose of rituximab within their second course of rituximab or rituximab-containing treatment regimen.

7. Major surgery, not related to debulking surgical procedures, within 21 days before screening.

8. Chemotherapy, cancer immunosuppressive therapy, radiotherapy, growth factors (except erythropoietin), or investigational agents within 28 days before administration of the first dose of test article. Subjects receiving high doses of corticosteroids must have had their doses tapered to a stable and acceptable level (i.e. physiological replacement dose) at least 28 days before administration of the first dose of test article. On dose days, subjects should not take any corticosteroids apart forfrom the premedication and corticosteroids included in the prescribed chemotherapy regimen described by the protocol, as well as any corticosteroids needed for physiological replacement.

9. Prior chemotherapy with nitrosoureas or mitomycin C within 6 weeks before administration of the first dose of test article.

10. Subjects who are not eligible for at least 1 of the 2 treatment options in arm 2.

11. Cardiac function, as measured by left ventricular ejection fraction (LVEF), is outside of the institutional limits of normal.

12. Female subjects who are pregnant or breastfeeding (if the subject is male, this criterion is considered to be not met).

13. Central nervous system (CNS) NHL; a lumbar puncture is not required unless CNS involvement with NHL is clinically suspected.

14. Subjects with known systemic vasculitides (eg, Wegener's granulomatosis, polyarteritis nodosa, systemic lupus erythematosus).

15. Known seropositivity for human immunodeficiency virus (HIV); current or chronic hepatitis B or hepatitis C infection.

16. Subjects with a history of veno-occlusive disease or chronic liver disease, such as cirrhosis or chronic hepatitis due to any cause, or are suspected of alcohol abuse.

17. Subjects with > grade 1 neuropathy.

18. Unstable or severe uncontrolled medical condition (eg, unstable cardiac function, unstable pulmonary condition, uncontrolled diabetes) or any important medical illness or abnormal laboratory finding that would, in the investigator’s judgment, increase the risk associated with the subject’s participation in the study.

19. Any evidence of serious active infection (ie, requiring an intravenous [IV] antibiotic or antiviral agent).

20. Concurrent active malignancy other than nonmelanoma skin cancer or carcinoma in situ of the cervix.

21. Subjects with previous malignancies are eligible provided that they have been disease free for 5 years or more. Subjects with a history of basal cell or squamous cell carc
