What was measured

Time to first onset of Grade ≥2 CRS in participants receiving prophylactic anakinra relative to onset of Grade ≥ 2 CRS in participants treated at the RP2D(s) in the Phase 1 dose escalation portion of the trial. Time to onset is calculated from the latest JCARH125 infusion prior to the first onset of Grade \>= 2 CRS. CRS grade is defined by the most severe symptom (excluding fever). Grade 2=moderate; Grade 3=severe; Grade 4=life-threatening

Analysis population: All participants with grade ≥2 CRS who received at least one infusion of JCARH125 (and at least one dose of anakinra as prophylactic intervention for phase 1 Anakinra) at dose level 600 x 10\^6 in phase 1 and in phase 1 Anakinra

Groups in this outcome

Phase 1 600 x 10^6 Cells

JCARH125 IV at dose level 600 x 10\^6 consisting of CD3+CAR+T cells

Phase 1 Anakinra 600 x 10^6 Cells

2 doses of 100 mg anakinra administered subcutaneously (SC) for 5 consecutive days + JCARH125 IV at dose level 600 x 10\^6 consisting of CD3+CAR+T cells
