• An extranodal lesion must be at least 10 mm x 10 mm.
6. Patient has low tumor burden FL defined as:
a. Serum LDH =1.5 upper limit of normal.
b. ß2-microglobulin =1.5 upper limit of normal.

7. Men and women of childbearing potential must agree to use a highly effective method of contraception throughout the study and for 12 months after the last dose of assigned treatment. A man or woman is of childbearing potential if, in the opinion of the investigator, he or she is biologically capable of having children and is sexually active.

Exclusion criteria:
Patients presenting with any of the following will not be included in the study:
1. Patients who are not candidates for rituximab monotherapy in the opinion of the investigator.
2. Evidence of histologic transformation to high-grade or diffuse large B-cell lymphoma.
3. Central nervous system or meningeal involvement or cord compression by the lymphoma (Brain imaging is not required, but may be conducted if clinically indicated).
4. Any previous history of T-cell lymphoma.
5. Subjects with = 5000/mm3 circulating lymphoma cells
6. Any prior systemic therapy for B-cell NHL, including chemotherapy, immunotherapy, or steroids. Patients may have received prior localized radiotherapy for FL (Low dose [10 mg oral prednisone or equivalent] or inhaled steroids for other conditions are acceptable).
7. Any prior treatment with rituximab.
8. Hypersensitivity to the active substances or to any of the excipients in rituximab-Pfizer or rituximab-EU.
9. History of allergy or prior hypersensitivity to murine, chimeric,
humanized, or human monoclonal antibody treatments.
10.Impaired bone marrow function as evidenced by hemoglobin < 9.0 g/dL, absolute neutrophil count (ANC) < 1.5 x 10x9 cells/L (1500/mm3) or a platelet count <75 x 10x9cells/L (75,000/mm3).
11. Symptomatic ischemic heart disease or NYHA Class II, III, or IV congestive heart failure.
12. Active infection with tuberculosis (TB). Patients with evidence of latent TB or a history of TB must have completed treatment or have initiated treatment for at least 1 month before the first dose of study treatment (Day 1). TB testing is required only if it is required by local regulations or practice.
13. Positive test for hepatitis B surface antigen (HBsAg), hepatitis B core
antibody (HBcAb), or anti-hepatitis C antibody (HCVAb), or seropositivity
for human immunodeficiency virus (HIV).
14. Any other active uncontrolled infection. Patients with an infection
must have initiated a course of treatment with an effective antimicrobial
a minimum of 7 days before the first dose of study treatment (Day 1)
and be free of symptoms from the infection.
15. Any history of another cancer during the last 5 years with the
exception of non-melanoma skin tumors, in situ cervical carcinoma, or in
situ breast cancer treated with curative intent with no history of
metastatic disease.
16. Administration of a live vaccine = 6 weeks before first dose of study treatment (Day 1).
17. Major surgery =28 days before first dose of study treatment.
18. Anticipated need for concomitant administration of any other experimental drug, or a concomitant chemotherapy, anticancer hormonal therapy, radiotherapy, or immunotherapy during study participation.
19. Participation in other studies involving investigational drug(s) (Phases 1-4) within 4 weeks or 5 half-lives, whichever is longer, before the current study begins and/or during study participation.
20. Any other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study.
21. Patients who are investigational site staff members directly involved in the conduct of the trial and their family members, site staff members otherwise supervised by the investigator, or patients who are Pfizer employees dir
