* 3 cycles (cycle=21 days) of mosunetuzumab with DHAX salvage chemotherapy (selected at the discretion of the treating physician).
* The first 3 patients in each arm will receive Dose Level 1 along with standard dosing of DHAX. The rate of dose-limiting toxicities will determine whether the subsequent 3 patients in each arm are enrolled at Dose Level 1, or alternatively at Dose Level -1.
* For patients tolerating Cycle 1 of treatment, Cycles 2 and 3 will consist of mosunetuzumab administered as a single dose on Day 1 along with DHAX. Patients will undergo PET-CT restaging prior to Cycle 3, and those achieving a CR (or PR, at their physician's discretion) will receive the Cycle 3 dose of mosunetuzumab and DHAX, followed by standard of care stem cell mobilization and autoSCT. Patients with SD or PD after restaging will discontinue study treatment.

* 3 cycles (cycle=21 days) of mosunetuzumab with ICE salvage chemotherapy (selected at the discretion of the treating physician).
* The first 3 patients in each arm will receive Dose Level 1 along with standard dosing of ICE. The rate of dose-limiting toxicities will determine whether the subsequent 3 patients in each arm are enrolled at Dose Level 1, or alternatively at Dose Level -1.
* For patients tolerating Cycle 1 of treatment, Cycles 2 and 3 will consist of mosunetuzumab administered as a single dose on Day 1 along with ICE. Patients will undergo PET-CT restaging prior to Cycle 3, and those achieving a CR (or PR, at their physician's discretion) will receive the Cycle 3 dose of mosunetuzumab and ICE, followed by standard of care stem cell mobilization and autoSCT. Patients with SD or PD after restaging will discontinue study treatment.

This is a two-arm, open-label, phase Ib single-site study with expansion cohorts testing the addition of mosunetuzumab to intensive platinum-based salvage chemotherapy in patients with relapsed/refractory aggressive B cell lymphoma intending to pursue consolidative autoSCT. The hypothesis of this study is that mosunetuzumab can be safely combined with platinum-based salvage chemotherapy in this patient population, and that this approach may outperform chemoimmunotherapy approaches that instead incorporate rituximab retreatment. The enrolling physician's choice of the chemotherapy backbone will determine a patient's assigned study arm (Arm A = DHAX, Arm B = ICE). The two arms will accrue patients to phase Ib and expansion cohorts as well as be analyzed independently.

Mosunetuzumab in Combination With Platinum-Based Salvage Chemotherapy in Autologous Stem Cell Transplant-Eligible Patients With Relapsed/Refractory Aggressive B Cell Lymphoma

A Phase Ib Study With Expansion Cohorts Evaluating the Safety and Efficacy of Mosunetuzumab in Combination With Platinum-Based Salvage Chemotherapy in Autologous Stem Cell Transplant-Eligible Patients With Relapsed/Refractory Aggressive B Cell Lymphoma

-Treatment-emergent adverse events (TEAE) are defined as adverse events possibly, probably, or definitely related to mosunetuzumab that occur on or after first dose of study treatment.

-As determined by PET-CT after Cycle 2 (PET2) of study treatment per Deauville 5-point scale (Lugano 2014 criteria).

* ORR: Number of participants with complete response (CR) and partial response (PR)
* As determined by PET-CT after Cycle 2 (PET2) of study treatment per Deauville 5-point scale (Lugano 2014 criteria).

-Defined as the time from start of study therapy to the first occurrence of disease progression as determined by the investigator with use of the Lugano Response Criteria or death from any cause.

-Overall survival (OS) is defined as the time from start of study therapy to death from any cause.

Tocilizumab is recommended for treatment of grade 2 CRS and required for grade 3 or 4 CRS. Tocilizumab should be administered by IV infusion for a maximum of 4 doses.
