1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

backgroundSequential CD19 and CD22 chimeric antigen receptor (CAR)-T cell therapy offers a promising approach to antigen-loss relapse in relapsed/refractory (R/R) B-cell acute lymphoblastic leukemia (B-ALL); however, research in adults remains limited.

methodsThis study aimed to evaluate the efficacy and safety of sequential CD19 and CD22 CAR-T cell therapy in adult patients with R/R B-ALL between November 2020 and November 2023 (ChiCTR2100053871). Key endpoints included the adverse event incidence, overall survival (OS), and leukemia-free survival (LFS).

resultsTwenty-three patients with a median age of 58.1 years (range 25.9-75.0) were enrolled. High-risk cytogenetic and genomic aberrations were identified in 43.5% of patients, and five patients had baseline extramedullary disease (EMD). The median interval between the two infusions was 3.8 months. Grade ≥ 3 hematological adverse events occurred at comparable rates after both infusions. Cytokine release syndrome was observed in 78.3% and 39.1% of patients after CD19 and CD22 CAR-T therapy, respectively. Two patients experienced grade 2 immune effector cell-associated neurotoxicity syndrome (ICANS) during CD19 CAR-T, and no ICANS was reported during CD22 CAR-T. The median OS was not reached with a median follow-up of 19.4 months (range 8.7-45.6), while the median LFS was 20.8 months. OS and LFS rates were 91.3% and 67.1% at 1 year and 58.6% and 47.0% at 2 years, respectively. Eight patients experienced relapse, with the cumulative incidence of relapse being 28.6% at 1 year and 42.5% at 2 years. Higher baseline leukemia burden (≥ 64% bone marrow blasts) and the presence of EMD were significant risk factors for inferior OS and LFS, respectively.

conclusionsSequential CAR-T cell therapy demonstrated durable efficacy and a manageable safety profile in R/R B-ALL, providing a viable option to address antigen-loss relapse and improve long-term outcomes in high-risk adult patients.
