What was measured

PFS is defined as the time from JCARH125 infusion until the earliest date of disease progression or death from any cause. Progressive disease (PD) is defined as (1) Increase of ≥25% from lowest confirmed response in one or more of the following: Serum M-protein absolute increase ≥0.5 g/dL; Serum M-protein increase ≥1 g/dL, if the lowest M component was ≥5 g/dL; Urine M protein absolute increase ≥200 mg/24 h; the difference between involved and uninvolved FLC levels absolute increase \>10 mg/dL; Bone marrow plasma-cell percentage irrespective of baseline status absolute increase ≥10%. (2) Appearance of a new lesion(s), ≥50% increase from nadir in SPDd of \>1 lesion, or ≥50% increase in the longest diameter of a previous lesion \>1 cm in short axis. (3) ≥50% increase in circulating plasma cells (minimum of 200 cells μL) if this is the only measure of disease.

Analysis population: All participants who received conforming JCARH125 cell product at the recommended phase 2 dose and have measurable disease at the last disease assessment prior to receiving JCARH125 infusion in phase 2 and in phase 2a
