      Trial Summary

      This study will evaluate the safety, pharmacokinetics, and preliminary efficacy of mosunetuzumab following first-line diffuse large B-cell lymphoma (DLBCL) immunochemotherapy in participants with a best response of stable disease or partial response, or in elderly/unfit participants with previously untreated DLBCL, or subcutaneous mosunetuzumab in combination with polatuzumab vedotin IV in elderly/unfit participants with previously untreated DLBCL.

      A Phase I/II Trial of Mosunetuzumab (BTCT4465A) as Consolidation Therapy in Patients With Diffuse Large B-Cell Lymphoma Following First-Line Immunotherapy and as Monotherapy or in Combination With Polatuzumab Vedotin in Elderly/Unfit Patients With Previously Untreated Diffuse Large B-Cell Lymphoma

      Eligibility Criteria

      All Gender
      ≥ 18 Years Age
      No Healthy Volunteers
      Inclusion Criteria

      Inclusion Criteria for All Cohorts

      • 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 > 1.0 cm in its longest diameter
      • Adequate hematologic function
      • Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1, or 2; with the exception of South Korea, where participants 80 years or older with ECOG >/= 2 will not be eligible

      Inclusion Criteria Specific to Cohort A

      Participants in Cohort A must also meet the following criteria for study entry:

      • Histologically confirmed DLBCL according to World Health Organization (WHO) 2016 expected to express the cluster of differentiation-20 (CD20) antigen
      • One prior therapy with any systemic anthracycline-based chemoimmunotherapy containing regimen for previously untreated DLBCL
      • Best response of SD or PR to prior systemic chemoimmunotherapy at the end of induction treatment in accordance with the Lugano 2014 criteria

      Inclusion Criteria Specific to Cohorts B and C

      Participants in Cohorts B and C must also meet the following criteria for study entry:

      • Previously untreated, histologically confirmed, DLBCL according to WHO 2016 classification
      • Age >/= 80 years, or
      • Age 65-79 years and considered ineligible for chemoimmuotherapy (R-CHOP) with at least one of the following: Impairment in at least two activity of daily living (ADL) components as defined in the protocol; impairment in at least two instrumental ADL components as defined in the protocol; cumulative illness rating scale - geriactic (CIRS-G) score of at least one cormorbidity with a severity score of 3-4 or a score of 2 in >/= 8 comorbidities; impairment in cardiac function, renal function, liver function, or other comorbidities such that the participant is unfit for full-dose immunochemotherapy, such as rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP)
      • Participants with an initial ECOG performance status of 3 may be considered during screening if the performance status is DLBCL-related and if pre-phase treatment during the screening phase (not more than 100 mg/day up to 7 days prior to Cycle 1 Day 1) results in an improvement of ECOG performance status to </= 2 prior to enrollment
