Untreated FolliculaR Lymphoma Treated With OBinituzumAb in a Non-interventional Study (URBAN)

PFS was defined as the time from the date of treatment initiation until the first documented PD measured by routine clinical care or death from any cause, whichever occurred first. According to standard Cheson criteria and Deauville 5-point scale, PD was defined as 20% increase in the sum of LD of target lesions; for small lymph nodes measuring < 15 mm post-therapy, a minimum absolute increase of 5 mm and the LD should exceed 15 mm; the appearance of a new lesion; any bone marrow involvement and any FDG-PET results. Kaplan-Meier estimate of the PFS2 rate at 2 years (that is, the estimated percentage of participants with PFS2 at Year 2) is presented.

Kaplan-Meier estimate of the PFS3 rate at 3 years (that is, the estimated percentage of participants with PFS3 at Year 3) is presented.

TTNT was defined as the time to initiation of subsequent systemic anti-cancer therapy following initiation of obinutuzumab containing therapy. Participants who did not start subsequent systemic anti-cancer therapy were censored at the date of the last study visit.

OS was defined as the time from initiation of study treatment to death from any cause. Participants who were still alive at the time of analysis and participants who were lost to follow-up were censored at their last time known to be alive.

TTLCB was defined as the time from first dose to loss of clinical benefit as assessed by the treating physician (single or multiple reasons possible: e.g. PD, deterioration in Eastern Cooperative Oncology Group Performance Status (ECOG PS), death, other). Participants who did not lose clinical benefit were censored at the date of the last study visit. Participants without post-baseline tumor assessments were censored at the time of their baseline visit unless death occurred prior to their first scheduled tumor assessment.

ORR was defined as the percentage of participants with a complete response (CR) or partial response (PR) at mid and end of induction (6 months), and during and after maintenance therapy (24 months), as per clinical practice, with and without FDG-PET. Per standard Cheson criteria and Deauville 5-point scale, CR was defined as complete disappearance of all target lesions \& all nodes with long axis < 10 mm or ≥ 30% decrease in sum of LD of target lesions with normalization of FDG-PET (Deauville score 1-3); no new lesions \& no bone marrow involvement. PR was defined as ≥ 30% decrease in sum of LD of target lesions but not a CR; positive FDG-PET (Deauville score 4-5); no new lesions and any bone marrow involvement. The Deauville 5-Point Scale is based on visual interpretation of FDG uptake. Scale ranges from 1 to 5, where 1 (best)=no FDG uptake; 2=FDG uptake ≤ mediastinum; 3=FDG uptake > mediastinum but ≤ liver; 4=FDG uptake moderately > liver; 5 (worst)=FDG uptake markedly > than liver.

An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.

An SAE is any AE that meets any of the following criteria: is fatal; life-threatening; requires or prolongs inpatient hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect in a neonate/infant born to a mother exposed to study medicine and is a significant medical event in the physician's judgment.

IRRs were defined as all AEs that occurred during or within 24 hours after study treatment infusion and were judged to be related to infusion of study treatment.

PFS=time from the date of treatment initiation until the first documented PD measured by routine clinical care or death from any cause, whichever occurred first. Per standard Cheson criteria \& Deauville 5-point scale, PD=20% increase in sum of LD of target lesions; for small lymph nodes measuring <15 mm post-therapy, a minimum absolute increase of 5 mm \& the LD should exceed 15 mm; appearance of a new lesion; any bone marrow involvement \& any FDG-PET results. The FLIPI tool predicts the prognosis of participants diagnosed with FL. Prognosis depends on 5 FLIPI risk factors: age >60 years, Ann Arbor stage III-IV, hemoglobin (Hb) level <12 grams per deciliter (gm/dL), >4 nodal areas \& raised lactate dehydrogenase (LDH) levels. Each factor was given a point if it was positive. FLIPI score range from 0-5 where 0-1 = low risk; 2=intermediate risk and 3-5=high risk. Higher score indicates worse prognosis. Participants who were event-free at 2 years, stratified by FLIPI score are presented.

PFS was defined as the time from the date of treatment initiation until the first documented PD measured by routine clinical care or death from any cause, whichever occurred first. PD was defined as outlined in the description of outcome measure 1 (POD24). ECOG-PS assessed participant's performance status on a 5 point scale where 0=fully active, able to carry on all pre-disease activities without restriction; 1=restricted in physically strenuous activity, but ambulatory, able to carry out light/sedentary work; 2=ambulatory, capable of all self-care, but unable to carry out any work activities (>50% of waking hours); 3=capable of only limited self-care, confined to bed/chair (>50% of waking hours); 4=completely disabled, cannot carry on any selfcare, totally confined to bed or chair and 5=Dead. Higher score=lower performance. Data for participants who were event-free at 2 years, stratified by ECOG-PS score are presented.
