Siltuximab

Multiple myeloma patients with persistent grade 1 CRS/ICANS for 12 hours or grade ≥2 CRS/ICANS after CAR-T therapy will receive Siltuximab (11 mg/kg) immediately. If symptoms persist for another 12 hours, repeat Siltuximab and corticosteroids are allowed. If unresolved or worsened, rescue therapy with tocilizumab, corticosteroids, or other medications will be given.
