What was measured

BOR=CR/PR per PET-CT/CT per MLRC. CR per PET-CT=complete MR in lymph nodes \& ELS, score=1, 2,3 with/without a residual mass on 5-PS; 1=no UT above background; 2=UT≤mediastinum;3=UT\>mediastinum but ≤liver;4=UT moderately\>liver;5=UT markedly higher than liver \&/or new lesions;no evidence of FDG-avid disease, bone marrow morphology=normal;if indeterminate, is IHC negative.PR per PET-CT=partial MR in lymph nodes \& ELS, score=4 or 5, reduced UT than BL \& residual mass of any size;residual UT\>UT in normal marrow but reduced than BL.CR per CT=complete radiologic response with target nodes/nodal masses regressed to ≤1.5cm in LDi \& no ELS of disease, absences of non-measured lesion;organ enlargement regressed to normal;no new lesions;bone marrow= normal;if indeterminate, is IHC negative.PR per CT=≥50% decrease in SPD of up to 6 target nodes \& extranodal sites;non-measured lesions=absent/normal/regressed/no increase;spleen=regressed by ≥50% in length beyond normal, no new lesions.

Analysis population: ITT population included all randomized participants in Phase II NF Cohort irrespective of whether or not they received the study treatment. As pre-specified in the protocol data reported is combined for Arms G and H. Values have been rounded off to the nearest whole number.

Groups in this outcome

Arm G+H (Phase II NF Cohort): Pola+BR in DLBCL

Participants with DLBCL received pola, 1.8 mg/kg, as IV infusion on Day 2 of Cycle 1 (each cycle is 21 days), and thereafter on Day 1 of Cycles 2 to 6. Participants also received bendamustine 90 mg/m\^2, as IV infusion on Days 2 and 3 of Cycle 1, and thereafter on Days 1 and 2 of Cycles 2 to 6 and obinutuzumab 1000 mg, as IV infusion on Days 1, 8, and 15 of Cycle 1 and on Day 1 of Cycles 2 to 6 in combination with pola.
