Experimental: Part 1: Dose Escalation r/r NHL - Dose finding in participants with r/r NHL: the study will explore different doses of glofitamab in the induction period, starting at a dose of 70 mcg administered in combination with standard of care doses of G/R CHOP and R-CHOP every 3 weeks (Q3W). Participants with r/r NHL will receive 6 cycles of induction treatment (G/R-CHOP). Glofitamab will be administered using step-up dosing for Cycle 2 on Days 8 and 15, followed by single doses on Day 8 for Cycles 3-6. Participants who achieve a complete response (CR), partial response (PR), or stable disease (SD) at the end of induction (EOInd) may optionally receive post-induction treatment (referred to as maintenance) with glofitamab alone.

The use of G versus R in Cycle 1 will be compared in parallel dose escalation cohorts.

Experimental: Part 2: DLBCL G/R-CHOP - Participants with untreated DLBCL will receive G-CHOP or R-CHOP in Cycle 1, followed by G/R-CHOP + glofitamab for subsequent cycles. Glofitamab will be administered using step-up dosing for Cycle 2 on Days 8 and 15, followed by single doses on Day 8 for Cycles 3-6 (up to 8). The starting dose of glofitamab for each arm may be one or more levels below the MTD/OBD determined in Part I.

Experimental: Part 2: DLBCL Pola-R-CHP - Participants with untreated DLBCL will receive Pola-R-CHP + glofitamab on Day 1 of each 21-day cycle for a maximum of 6 cycles. Glofitamab will be administered using step-up dosing for Cycle 2 on Days 8 and 15, followed by single doses on Day 8 for Cycles 3-6. The starting dose of glofitamab for each arm may be one or more levels below the MTD/OBD determined in Part I.

Summary
Brief summary
This is a phase 1B, multi-center, dose-finding study of glofitamab administered in combination with obinutuzumab (Gazyva; \[G\]), rituximab (R) and standard doses of CHOP (G/R-CHOP or R-CHOP) in participants with r/r NHL and G/R CHOP or Pola-R-CHP in participants with untreated diffuse large B-cell lymphoma (DLBCL). Evaluating the safety, preliminary activity, pharmacokinetic (PK), and pharmacodynamic effects of this combination will be the main objectives of this study. The study is divided in two parts:

* Part I: Dose finding in participants with r/r NHL; test use of G vs R in Cycle 1
* Part II: Dose Expansion. The maximum tolerated dose or optimal biological dose (MTD or OBD) will be further assessed in participants with untreated DLBCL (\>18 years of age with an age-adjusted International Prognostic Index (IPI) of 2-5). Glofitamab will be studied in combination with R-CHOP and Pola-R-CHP.
