Arm Intervention/treatment
Experimental: Part I: Dose-escalation of RO7122290
The dose-escalation of RO7122290 will use a QW dosing schedule of RO7122290 in combination with a Q3W dosing interval for cibisatamab with obinutuzumab pre-treatment. The starting dose for RO7122290 will be 35 mg, which represents the human equivalent dose for the minimal pharmacologically active dose (1 mg/kg) in mice.
Drug: RO7122290
RO7122290 will be administered using a QW (Part I) or Q3W (Part I or Part II) schedule in combination with 100 mg cibisatamab Q3W with obinutuzumab pre-treatment. The maximum dose of RO7122290 to be explored in combination with cibisatamab with obinutuzumab pre-treatment in this study is 500 mg for the QW dosing interval (Part I) or 1500 mg for the Q3W dosing interval (Part I or Part II).

Drug: Cibisatamab
Cibisatamab will be administered to participants at a fixed dose of 100 mg Q3W (100 mg on Day 1 of each 21-day cycle).

Drug: Obinutuzumab
Obinutuzumab will be administered as a split dose over two consecutive days (1000 mg on Day -13 and Day -12) or as a single dose given in 1 day (2000 mg on Day -13) at the Investigator's discretion.

Experimental: Part II: Dose-expansion of RO7122290
Part II of this study will evaluate selected dose levels of RO7122290 from Part I (a QW RO712290 administration in combination with a Q3W cibisatamab administration with obinutuzumab pre-treatment) in a Q3W regimen in combination with a Q3W cibisatamab administration with obinutuzumab pre-treatment.
Drug: RO7122290
RO7122290 will be administered using a QW (Part I) or Q3W (Part I or Part II) schedule in combination with 100 mg cibisatamab Q3W with obinutuzumab pre-treatment. The maximum dose of RO7122290 to be explored in combination with cibisatamab with obinutuzumab pre-treatment in this study is 500 mg for the QW dosing interval (Part I) or 1500 mg for the Q3W dosing interval (Part I or Part II).

Drug: Cibisatamab
Cibisatamab will be administered to participants at a fixed dose of 100 mg Q3W (100 mg on Day 1 of each 21-day cycle).

Drug: Obinutuzumab
Obinutuzumab will be administered as a split dose over two consecutive days (1000 mg on Day -13 and Day -12) or as a single dose given in 1 day (2000 mg on Day -13) at the Investigator's discretion.




Primary Outcome Measures :
