Interventions and Outcome Measures

Arms

experimental: Teclistamab/Tocilizumab

Participants will receive step up dosing of Teclistamab following the recommended dosage of TECVAYLI™ USPI followed by weekly dosing for twelve 28-day cycles, until disease progression, unacceptable toxicity, or the EOT (end of Cycle 12). Teclistamab dosing may be reduced to once every 2 weeks for participants who achieve partial response (PR) or better after 6 months of therapy.

experimental: Talquetamab/Tocilizumab

Participants will receive step up dosing of Talquetamab following the recommended dosage of TALVEY™ USPI followed by every 2 week dosing for six 28-day cycles, until disease progression, unacceptable toxicity, or the EOT (end of Cycle 6). Talquetamab dosing may be reduced to once every 4 weeks for participants who achieve very good partial response (VGPR) or better after Cycle 4. Participants in the talquetemab arm cannot be re-screened for or re-enrolled into the teclistamab arm.

experimental: Teclistamab/Oral Dexamethasone

Participants will receive step-up dosing of Teclistamab followed by weekly dosing for two cycles, every other week during Cycles 3-6 and once every 4 weeks from Cycles 7 through 12 until disease progression, unacceptable toxicity, or the EOT (end of Cycle 12). Teclistamab dosing may be reduced to once every 4 weeks for participants who achieve very good partial response (VGPR) or better starting with Cycle 3.

Interventions

Teclistamab

Teclistamab will be administered subcutaneously at step-up doses on Day 1, Day 4 and Day 8, one week after first treatment dose and weekly thereafter. In participants who have a partial response (PR) or better after 6 months of therapy, dosing frequency may be reduced to every 2 weeks.

Talquetamab

Talquetamab will be administered subcutaneously at step-up doses on Day 1, Day 4, Day 8 and Day 15, one week after first treatment dose and every 2 weeks thereafter. In participants who have a very good partial response (VGPR) or better after Cycle 4, dosing frequency may be reduced to every 4 weeks

Tocilizumab

Tocilizumab will be administered as a pretreatment medication in advance of administration of the first step-up dose of teclistamab or talquetamab on Cycle 1 Day 1.

Oral Dexamethasone

Oral dexamethasone will be administered as a pretreatment medication every 12 hours in 3 doses (PM/AM/PM) following each step-up dose and the first full dose of teclistamab in Cycle 1. A total of 9 doses of oral dexamethasone will be administered.

Primary outcome measure

  • Incidence of CRS of any grade during the first two cycles [ Time Frame: From first dose of teclistamab or talquetamab, from Day 1 first step-up dose to the end of Cycle 2 (each cycle is 28 days) ]
