1. Systemic inflammation in patients with severe neurotoxicity (NTX).
Systemic inflammation in patients with severe neurotoxicity (NTX). A, Severe NTX associated with higher peak CAR T expansion (vector copy number per mL) in blood. B, Maximum temperature, serum CRP, and ferritin are shown for patients at the indicated time windows after CAR T-cell infusion. C, Volcano plots visualizing the relative significance of serum cytokines associated with severe NTX by pre-lymphodepletion, day 3 after infusion, and peak after infusion during the first 28 days. Cytokines with P < 0.05 are indicated in red. D, Serum cytokine concentrations within indicated time windows comparing grade 0–2 versus grade 3–4 NTX for significant cytokines in C. All are maximum cytokine concentrations within the indicated time window except for EGF, which is minimum cytokine concentration. For B and D, Within each time window, the y-axis shows the mean ± SEM of the values for all patients according to the NTX severity. P values were determined using the Kruskal–Wallis test. ***, P < 0.001; **, < P < 0.01; *, 0.01 < P < VCN, vector copy number; Pre-LD, prior to the start of lymphodepletion chemotherapy; d0, prior to CAR T-cell infusion; d, days after CAR T-cell infusion; G, grade.
