Anti-CD19 antibody cotreatment enhances serial killing activity of anti-CD19 CAR-T/-NK cells and reduces trogocytosis.
Article in Blood, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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.
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
abstractAnti-CD19 chimeric antigen receptor (CAR)-engineered T and natural killer (NK) cell therapies have revolutionized the treatment of B-cell malignancies, but challenges including CD19 antigen loss greatly hinder their full therapeutic potential. Here, we revealed that cotreatment with anti-CD19 monoclonal antibody enhances antitumor activity of anti-CD19 CAR-T and -NK cells. Even though the treated antibody interferes with CD19 antigen binding of CAR, it significantly induces rapid detachment of anti-CD19 CAR effector cells from target cells, facilitating improved serial killing. This reduced interaction between CAR effector cells and target cells also leads to the alleviation of CAR-mediated trogocytosis. Interestingly, cotreatment with anti-CD19 antibody reveals time-dependent effects on the antitumor activity of anti-CD19 CAR-T cells, characterized by a reduction in early T cell activation followed by sustained high activity during prolonged exposure to target cells. This temporal modulation ultimately results in enhanced antitumor potency in vivo. These findings underscore the improved therapeutic efficacy achieved by combining anti-CD19 antibody with anti-CD19 CAR-T or -NK cells against B-cell malignancies.
