1. Signed written informed consent.
2. Male or female subjects aged =18 years of age.
3. Histologically confirmed, Grade 1-3a, previously untreated, CD20-positive, LTB-FL as per Groupe D’Etude des Lymphomes Folliculaires (GELF) based criteria. Subjects must have sufficient tissue samples available for the central pathology review (Section 8.1.1), and a centrally-confirmed diagnosis prior to being randomised. Should a subject be eligible as per the central imaging review but not as per the Study Centre Review the subject will be considered eligible if confirmed both by the Investigator and the Medical Monitor. For any other disagreement in eligibility the subject will be considered ineligible.
4. Ann Arbor Stage II to IV.
5. ECOG status of 0 to 1.
6. Low tumour burden follicular lymphoma defined as:
· As per central radiological assessment, nodal or extranodal mass involvement with diameter measuring <7 cm
· As per central radiological assessment, involvement of =3 nodal sites with diameter measuring >3 cm
· Absence of systemic symptoms or B-symptoms* (asymptomatic)
*B-symptoms defined as weight loss >10% within last 6 months, recurrent or continuous night sweats, intermittent or continuous fever recorded as axillary or oral temperature >38°C for at least 3 days
· As per central radiological assessment, absence of splenomegaly (defined as spleen size higher than 16 cm by computed tomography [CT] scan)
· Absence of risk of vital organ compression based on clinical finding
· Absence of leukemic phase (leukemic phase defined as a count >5,000/µL of circulating tumour cells)
· Absence of clinically significant cytopenias (defined as a platelet count of <100,000/µL, haemoglobin <10 g/dL, or absolute neutrophil count <1,500/µL)
· Absence of clinically significant serous effusion based on clinical examination and CT scan
· Serum LDH not higher than the upper limit of normal (ULN) by local laboratory.
7. Subject has at least 1 measurable tumour mass in 2 dimensions as per central radiological assessment, and the mass must be:
· Nodal lesion >15 mm in the longest dimension; or
· Nodal lesion >10 mm to =15 mm in the longest dimension and >10 mm in the shortest dimension; or
· Extranodal lesion with both long and short dimensions =10 mm.
8. Creatinine clearance =45 mL/min as calculated by the Cockcroft-Gault method.
9. Aspartate transaminase, alanine transaminase, alkaline phosphatase values =3 × ULN, total or conjugated bilirubin values =1.5 × ULN.
10. Life expectancy =3 months.
11. Able to comply with the study protocol.
12. If female subject, then subject should be non-pregnant, non-lactating. Adequate contraception or post-menopausal/non-childbearing status. Women of childbearing potential must practice effective birth control for the duration of the study and for 12 months after the last study drug dose. For this same duration, male subjects participating in the study should avoid passing the semen to female partners during sexual intercourse.
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 184
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 100
1. Prior use of rituximab or any CD20 monoclonal antibody for any reason.
2. Any contraindication to the use of rituximab.
3. Any prior therapy for follicular lymphoma (including but not limited to chemotherapy, radiotherapy).
4. Subjects who, in the opinion of the Investigator, require additional concomitant treatment for lymphoma.
5. Evidence of histologic transformation to high grade lymphoma or diffuse large B-cell lymphoma.
6. Known Central Nervous System (CNS) involvement by lymphoma. (Note: CNS imaging is not required unless clinically indicated).
7. Subjects on chronic supra-substitutive doses (defined as doses in excess of 7.5 mg per day of prednis one or prednis one equivalent for a period longer than 3 weeks) of systemic glucocorticoids.
8. Prior malignancy (including recurrence) within 5 years of screening, other than non-melanoma skin cancer or intraepithelial cervical neoplasia, which should have been successfully treated more than 1 year before study inclusion.
9. Subjects with any of the following: known seropositivity for or history of active viral infection with human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg) positive or hepatitis B core antibody positive, hepatitis C virus (HCV) antibody positive.
10. Subjects with positive serological test for hepatitis B surface antigen HBsAg), hepatitis B core antibody (HBcAb) or hepatitis C virus (HCV) antibody can only be included in the study if any of the following is fulfilled.
-Subjects with a negative HBsAg and positive total HBcAb must have a HBV deoxyribonucleic acid (DNA) level <20 IU/mL (or 112 copies/mL) by polymerase chain reaction (PCR) to participate in the study. In addition, it is required for these subjects to follow consultation with a hepatologist /relevant expert regarding initiation,monitoring, and use of HBV antiviral therapy and the subject must be willing to undergo PCR HBV DNA testing during treatment and agree to receive treatment as indicated. HBV DNA re-test will be performed as per the
schedule of assessments (ref. table no. 1-1) and further as needed, at the discretion of the Investigator.
-Subjects with a positive test because of HBV vaccination may be included (i.e., HBsAg negative, anti-HBs+, HBcAb–).
-Subjects positive for HCV antibody are eligible only if the PCR test for HCV ribonucleic acid (RNA) is negative.
11. Subjects with active tuberculosis (TB). Subjects 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 drug (Day 1). If latent TB is suspected based on clinical or epidemiological grounds, it should be further investigated using the tuberculosis testing as appropriate following local practice or investigator judgment.
12. Subjects who have received a live vaccine within last 3 months of the first administration of study drug. [Note: A need may arise for trial subjects to
receive vaccine against COVID-19 while being a part of the study. All such decisions will be taken at the discretion of the Investigator in consultation with the CRO / Sponsor after due consideration to subjects’ safety, national health policy of the respective country and overall need by the subject for such vaccine during the time of study participation].
13. Subjects with an active uncontrolled infection requiring systemic treatment at Screening or history of documented recurrent clinically significant infection within 6 months o
