This could be influenced by the quality of the individual CAR-T infusion product. To shed some light on this, clinical outcome was correlated to characteristics of CAR-T infusion products.\n\nIn this phase II study, patients with B-cell lymphoma (n = 23) or leukemia (n = 1) received one or two infusions of third-generation CD19-directed CAR-Ts (2 \u00d7 108/m2). The clinical trial was registered at clinicaltrials.gov: NCT03068416. We investigated the transcriptional profile of individual CD19 CAR-T infusion products using targeted single-cell RNA sequencing and multicolor flow cytometry.\n\nTwo CAR-T infusions were not better than one in the settings used in this study. As for the CAR-T infusion products, we found that effector-like CD8+CAR-Ts with a high polyfunctionality, high cytotoxic and cytokine production profile, and low dysfunctional signature were associated with clinical response. An extended ex vivo expansion time during CAR-T manufacturing negatively influenced the proportion of effector CD8+CAR-Ts in the infusion product.\n\nWe identified cell-intrinsic characteristics of effector CD8+CAR-Ts correlating with response that could be used as an indicator for clinical outcome. The results in the study also serve as a guide to CAR-T manufacturing practices.", "doi": "10.1158/1078-0432.CCR-23-0178", "pmid": "37540566", "labels": [], "xrefs": [{"db": "pmc", "key": "PMC10570681"}, {"db": "pii", "key": "728314"}, {"db": "ClinicalTrials.gov", "key": "NCT03068416"}, {"db": "figshare", "key": "20208764"}], "notes": [], "created": "2026-08-20T12:12:20.782Z", "modified": "2026-08-20T12:12:21.097Z"}]}
