A Phase Ib/II, Open-Label, Multicenter, Randomized, Controlled Study Investigating the Safety, Tolerability, Pharmacokinetics, and Efficacy of Mosunetuzumab (BTCT4465A) in Combination With CHOP or CHP-Polatuzumab Vedotin in Patients With B-Cell Non-Hodgkin Lymphoma

This study will evaluate the safety, pharmacokinetics, and preliminary efficacy of
mosunetuzumab in combination with cyclophosphamide, doxorubicin, vincristine, and prednisone
(M-CHOP) and, subsequently, in combination with cyclophosphamide, doxorubicin, and prednisone
(CHP) plus polatuzumab vedotin (CHP-pola) in participants with relapsed or refractory (R/R)
B-cell non-Hodgkin lymphoma (NHL), and in previously untreated participants with diffuse
large B-cell lymphoma (DLBCL).


Inclusion Criteria for Phase Ib and Phase II Portions

- At least one bi-dimensionally measurable nodal lesion, defined as > 1.5 cm in its
longest dimension, or one bi-dimensionally measurable extranodal lesion, defined as >

therapy

- Treatment with at least one prior CD20-directed therapy

- Group B only: no prior treatment with polatuzumab vedotin

Inclusion Criteria for Phase II Portion

Participants must also meet the following criteria for study entry in the Phase II portion:
