A Study of Polatuzumab Vedotin (DCDS4501A) in Combination With Rituximab or Obinutuzumab Plus Bendamustine in Participants With Relapsed or Refractory Follicular or Diffuse Large B-Cell Lymphoma

An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. AEs were reported based on the National Cancer Institute Common Terminology Criteria for AEs, version 4.0 (NCI-CTCAE, v4.0).

The number of participants with positive results for ADA against pola at Baseline and at any of the post-baseline assessment time-points were reported. Participants positive at any post-baseline time points were post-baseline evaluable participants determined to have "Treatment-induced ADAs" or "Treatment-enhanced ADA" during the study period. Treatment-induced ADA = negative or missing baseline ADA result(s) and at least one positive post-baseline ADA result. Treatment-enhanced ADA = a participant with positive ADA result at baseline who has one or more post-baseline titer results that are at least 0.60 titer unit (t.u.) greater than the baseline titer result. Treatment emergent ADA is the sum of treatment-induced ADAs and treatment enhanced ADAs. Values have been rounded off to the nearest whole number.

CR was assessed by IRC at PRA according to Modified Lugano Response Criteria (MLRC). Per MLRC, CR based on PET-CT was defined as complete metabolic response (MR) in lymph nodes and extralymphatic sites (ELS) with a score of 1, 2, or 3 with or without residual mass, on 5-point scale (5PS) where 1=no uptake above background; 2=uptake ≤ mediastinum; 3=uptake > mediastinum but ≤ liver; 4=uptake moderately > liver; 5=uptake markedly higher than liver and/or new lesions no evidence of fluorodeoxyglucose (FDG)-avid disease in bone marrow. Bone marrow is normal by morphology; if indeterminate, immunohistochemistry (IHC) negative. As pre-specified in the protocol data reported is combined for Arms G and H. The analysis was done 6-8 weeks after Cycle 6, Day 1 (each cycle is 21 days for DLBCL cohorts and 28 days for FL cohorts) or after final dose of study treatment.

The TINAS is an 11-item questionnaire that assesses the severity of neuropathy-related symptoms in the last 24 hours. The 11 items assessed were: hot/burning sensations in hands/feet, sensations pins and needles arms/legs, numbness or tingling in hands/feet, sensations of electric shock, pain when touching cold things, cramps in hands/feet, discomfort when touching things, discomfort skin contact with something, trouble grasping small objects, trouble walking loss feeling legs/feet, difficulty balance loss feeling leg/feet.
