Patient-reported symptom burden, neuropathy, and physical condition/fatigue as measured by the EORTC-QLQ-NHL-HG29 questionnaire. The EORTC-QLQ-NHL-HG29 is the NHL-aggressive module of QLQ-C30; and it consists of 5 scales: Symptom burden due to disease and/or treatment (7 items), Neuropathy (2 items), Physical condition/Fatigue (5 items), Emotional impacts (4 items), and Worries/Fears health and functioning (11 items). Items are rated using a 4-point response scale ("not at all," "a little," "quite a bit," and "very much"). A higher score for all the multi-item scales and items represents a higher level of symptomatology or problems.

Patient-reported global health status (GHS), role, and physical function as measured by the EORTC-QLQ-C30 questionnaire. The EORTC QLQ-30 contains 30 questions that incorporate 5 functional scales (physical functioning, role functioning, emotional functioning, cognitive functioning, and social functioning), 1 global health status scale, 3 symptom scales (fatigue, nausea and vomiting, and pain), and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). The participant answers questions about their health during the past week. There are 28 questions answered on a 4-point scale where 1 =Not at all (best) to 4 =Very Much (worst) and 2 questions answered on a 7-point scale where 1 =Very poor (worst) to 7 =Excellent (best).

Number of participants with TEAEs, including laboratory values, vital signs, electrocardiogram results, and physical examination findings, graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) v5.0.
