Description of intervention(s) / exposure
Treatment: Drugs - Cevostamab
Treatment: Drugs - Tocilizumab

Experimental: Arm A: Single Step Dose Escalation for Cevostamab - Study drug will be administered intravenously on a 21-day cycle. The step-up dose will be given on Cycle 1 Day 1 and the target dose will be given on C1D8. Subsequently the target dose will be administered on Day 1 of each 21-day cycle.

Experimental: Arm B: Double Step Dose Escalation for Cevostamab - In Cycle 1, participants will receive 2 step-up doses and a target dose. The step-up dose will be given on Cycle 1 Day 1 and C1D8. The target dose will be given on C1D15. Subsequently the target dose will be administered on Day 1 of each 21-day cycle.

Experimental: Arm C: Single Step Dose Expansion for Cevostamab - The single step dose expansion stage of the study may use the dosing and assessment schedule from the single dose escalation arm in Cycle 1, based on data from Arm A.

Experimental: Arm D: Double Step Dose Expansion for Cevostamab - The double step dose expansion stage of the study may use the dosing and assessment schedule from the double step dose escalation arm in Cycle 1, based on data from Arm B.

Experimental: Arm E: Expansion Phase for Tocilizumab Pretreatment - All participants will receive a single dose of tocilizumab intravenously. An additional dose of tocilizumab may be instituted as premedication for subsequent Cycle 1 dose(s) of cevostamab and Cycle 1 cevostamab doses for other treatment arms.

Experimental: Arm F: Single Step Dose Expansion for Cevostamab - The single step dose expansion stage of the study may use the dosing and assessment schedule from the single dose escalation arm in Cycle 1, based on data from Arm A.

Experimental: Arm G: Double Step Dose Expansion for Cevostamab - The double step dose expansion stage of the study may use the dosing and assessment schedule from the double step dose escalation arm in Cycle 1, based on data from Arm B.

Experimental: Arm H: Triple Step Dose Escalation for Cevostamab - In Cycle 1, participants will receive 3 step-up doses and a target dose. The doses will be given on Cycle 1 Days 1, 2-4, 8, and 9-11. Subsequently the target dose will be administered on Day 1 of each 21-day cycle.

Experimental: Arm I: Triple Step Dose Expansion for Cevostamab - The triple step dose expansion stage of the study may use the dosing and assessment schedule from the triple step dose escalation arm in Cycle 1, based on data from Arm H.

Experimental: Arm J: Expansion Phase for Tocilizumab Pretreatment - All participants will receive a single dose of tocilizumab intravenously. An additional dose of tocilizumab may be instituted as premedication for subsequent Cycle 1 dose(s) of cevostamab and Cycle 1 cevostamab doses for other treatment arms.

Experimental: Arm K: Compressed Double Step Dose Expansion for Cevostamab - In Cycle 1, participants will receive 2 step-up doses and a target dose. The doses will be given on Cycle 1 Days 1, 4, and 8. Subsequently the target dose will be administered on Day 1 of each 21-day cycle.


Treatment: Drugs: Cevostamab
Cevostamab will be administered intravenously on a 21-day cycle, up to a total of 17 cycles.

Treatment: Drugs: Tocilizumab
Tocilizumab will be administered as premedication during Cycle 1.
