Study Endpoints
Primary Endpoints
Incidence of all-grade cytokine release syndrome
Up to 28 days after beginning treatment

The primary objective is to evaluate the feasibility and efficacy of prophylactic administration of siltuximab prior to infusion of the first dose of epcoritamab with the purpose of preventing all-grade CRS, as measured by incidence of all-grade cytokine release syndrome.

Secondary Endpoints
Incidence of grade ≥ 2 cytokine release syndrome
Up to 28 days after beginning treatment
Incidence of all grade and grade ≥ 2 ICANS after siltuximab prophylaxis
Up to 28 days beginning treatment
Incidence of adverse events during Cycle 1 (Day 1 - 28)
Up to 28 days after beginning treatment

ArmTypeDescription
Prophylactic siltuximab + epcoritamabEXPERIMENTALSiltuximab Administration: • Participants will receive a single dose of prophylactic siltuximab, 11mg/kg, started 1 hour prior (+/- 60 minutes) to the infusion of epcoritamab. There is no planned dose escalation of siltuximab and epcoritamab dosing will be done following the standard planned ramp-up over the course of the first 3 weeks Epcoritamab Infusion: • The treatment regimen of epcoritamab is done in 28-day cycles. Epcoritamab is to be administered by subcutaneous injection. Participants can be treated for up to 24 cycles. Participants who achieve complete remission at the time of their disease response assessment after 12 cycles may be considered for early discontinuation of treatment.
