This is a Randomized, Double-blind, Multi-center, Multi-national Trial to Evaluate the statistical equivalence of efficacy, safety and immunogenicity of SAIT101 Versus Rituximab as a First-line Immunotherapy Treatment in asymptomatic patients with Low Tumor Burden Follicular Lymphoma.

This is a Randomized, Double-blind, Multi-center, Multi-national Trial to Evaluate the statistical equivalence of efficacy, safety and immunogenicity of SAIT101 Versus Rituximab as a First-line Immunotherapy Treatment in asymptomatic patients with Low Tumor Burden Follicular Lymphoma. Patients will be randomized in a 1:1 ratio to receive study drug once a week for 4 weeks, and will then be followed up for up to 52 weeks after the first dose. Randomization will be stratified by inclusion in the PK/PD sub-population and Follicular lymphoma international prognostic index 2 (FLIPI-2) score.

Visits are scheduled at Weeks 1, 2, 3, and 4 (study drug infusion visits), and then at Weeks 5, 12, 20, 28, 36, and 52 (i.e., End of Study \[EOS\]). Efficacy response assessments will be performed at Weeks 12 and 28, while safety assessments will continue until end of Study (EOS).

The primary objectives is to compare the efficacy of SAIT101 with rituximab licensed in the European Union (hereafter designated MabThera®, brand name in EU) when administered as a first-line immunotherapy in patients with low tumor burden follicular lymphoma (LTBFL) and the secondary objectives is to evaluate SAIT101 versus MabThera® with respect to safety and tolerability, immunogenicity and Pharmacokinetics (PK)/Pharmacodynamics (PD) in a sub-population of patients.

All AEs were coded using the Medical Dictionary for Regulatory Activities (MedDRA) v22.1. If an AE changed from non-SAE to be an SAE, it was treated as a new event and was counted as 2 events in the AE summary. A treatment-emergent AE (TEAE) was defined as any AE with an onset date on or after the date of the first dose of study treatment until Week 28, or the End of Study (EOS) visit, if earlier.

The ECOG score is used in the evaluation of cancer patients and can help with prognosis and management of the malignant condition because performance status is highly correlated with survival. A higher ECOG rating score generally equates to a worst outcome. ECOG scores 0 and 1 are defined as:

ECOG Score 0: Asymptomatic (Fully active, able to carry on all pre-disease activities without restriction);

ECOG Score 1: Symptomatic but completely ambulatory (Restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature.

Ann Arbor staging is the staging system for lymphomas, both in Hodgkin's lymphoma and non-Hodgkin lymphoma.

Stage I indicates that the cancer is located in a single region.

Stage II indicates that the cancer is located in two separate regions, an affected lymph node or lymphatic organ and a second affected area.

Stage III indicates that the cancer has spread to both sides of the diaphragm.

Stage IV indicates diffuse or disseminated involvement of one or more extralymphatic organs.

Ann Arbor Staging

Ann Arbor staging is the staging system for lymphomas, both in Hodgkin's lymphoma (formerly designated Hodgkin's disease) and non-Hodgkin lymphoma (abbreviated NHL). It was initially developed for Hodgkin's, but has some use in NHL. It has roughly the same function as TNM staging in solid tumors

Ann Arbor Clinical Stage (CS) as obtained by doctor's examination and tests, An Arbor Pathological Stage (PS) as obtained by exploratory laparotomy with splenectomy.

Type of Ann Arbor Staging

Follicular Lymphoma International Prognostic Index (FLIPI) score of 0 to 1 is considered "low risk" with a 10 year overall survival of 70%. A score of 2 is considered "intermediate risk" with a 10 year overall survival of 50%. Finally, a score of ≥ 3 is considered "high risk" with a 10 year overall survival of 35%.
